"
was responsive when i called and was prompt when he came over for the estimate. He is personable and honest. He explained what he was going to do and why doing" it that way was the best way to do it. On the day of the insulation he and his crew showed up on time (a little early even), were quick, efficient, courteous and thorough. They had to cut a hole in my ceiling and didn't make any mess. They worked around the HVAC unit that is in my attic and showed me their work when they were done. I didn't get any other quotes to compare prices but I was comfortable with his price.

"We discovered that we had no insulation below a cantilevered floor off the back of our kitchen, and we were losing a lot of heat as it got colder. We called Davenport and several other" DC licensed insulation companies for estimates. Davenport came quickly and gave us an estimate in October. The person who came out to do the estimate,
Klakring, seemed knowledgeable and friendly, and he gave us several options at different price points to solve the problem. He also took a look at some other areas where we had questions about insulation and was happy to answer our questions without trying to sell us unnecessary products like other companies. They were patient with us as we got several other estimates and did not employ any high pressure sales tactics. For various reasons, we waited until February to schedule the installation, and Davenport honored the quote from October and were able to schedule quickly. The price would have been lower, but our job was smaller than their mandatory minimum for the cost of bringing out the spray foam equipment and crew. Compared to other estimates we received, though, the price, even with the mandatory minimum, was still quite reasonable. The workers were punctual, clean, and respectful, and they finished quickly. There are a few spots where the foam insulation is not as thick as the rest, but overall, we were very pleased with the results, particularly the marked difference in the temperature of the floor, which is now the same temperature as the floor in the rest of the house above the conditioned basement. We would definitely go with Davenport again for any future insulation needs.

The Angie's List Guide to Winter Maintenance

It's the time of year when the winter weather can take a toll. Follow this winter maintenance checklist to protect your home, your car and your health.

Without proper insulation and venting in your attic, icicles can form on your eaves, leading to a damaging ice dam on your roof, says Neubecker. (Photo courtesy of Angie's List member Donna B. of Mendota Heights, Minn.)

Avoid ice dams with proper attic insulation

Do you have icicles forming on your eaves and gutters and ice collecting on your roof? An ice dam can cause serious problems without proper insulation.

Google and read about it. Some people swear by it, though their comments sound suspiciously like they were all written by the same person. Some call it a rip off - expecially people paying $6000-8000 for what would normally be a $1,000 range job.

I would not call it an outright fraud as they are providing a product that has some potential merit in the right application, but from a technical standpoint it sounds suspicious. They claim a 1/4 mat with doiuble sided foil facing is R-16 insulation. This at least is deceptive - they appear to be saying its radiant heat reflective properties give the equivalent of R-16 insulation, because there is NO WAY 1/4" foam is going to yield R-16 in an ASTM test for insulation, which is a thermal conductivity test. Would be lucky to get R-2 or so as an insulator, so this is basically a radiant barrier. Competing products from national brandname manufacturers list R value of 3.8-4.2 for one inch mats, so the equivalent for this 1/4" mat would be expected to be in the R1 range.

Properly installed, with ventilation on BOTH sides, it can be slightly effective in reducing radiant heat loss from the house, and more effective in reflecting heat in the attic from coming down into the house. However, from a thermodynamic and vapor control standpoint, they are trouble unless their integration into the house envelope is designed VERY carefully. Short explanation:

1) for keeping heat in the house, if they are installed above the attic floor insulation they can slightly limit air loss through the ceiling, and reflect radiant heat back down, resulting in warmer insulation, hence a warmer ceiling - but not as marked an improvement as added insulation would give.

2) for keeping attic heat from getting into the ceiling, they do reflect back a good portion of the radiant heat coming from the roof sheathing. This reduces the attic floor insulation surface temperature, so can reduce air conditioning cost. it does increase teh temperature in the attic, which can be very bad for support timbers and the roof sheathing.

3) the worst thing about how this type of foil radiant barrier is used is that, unless it has free air space on both sides, it acts as a vapor barrier. In the typicall application as a blanket over attic floor insulation, it traps any moisture coming up from the house, and can cause mildew and rot, especially in climates where the outdoor temperature gets quite cold.

4) the attic fans are generally a last resort measure - the normal house does much better, at no energy cost, using ridge vents with adequate eave openings to provide ventilation and cooling in the attic.

5) their effectiveness in winter heat diminshes rapidly with time - tests of attic radiant barriers show they lose about half their effectvieness within 5 years, because even a light dust coating greatly reduces their ability to reflect radiant heat, and greatly increases the absorption of heat from the hot air above them.

6) pay attention to cost - from what I see, their installed cost is many times the cost of normal insualtion or radiant barrier placement.

I would say, in summary, buyer beware, and I would be inherently leery of a product being sold the same way timeshares and "secret" moneymaking schemes are.

?

Obviously this is not a timely response to the initial question. However, for those who may be reading these answers at a later time, a couple of added thoughts:

1) the radiant barrier being discussed is basically heavy-duty metal foil or metallized surface on a plastic sheet, intended to reflect RADIATED heat (infrared radiation - think heat light, or heat you can feel at a distance radiated from a fireplace), the same way a mirror reflects light. Radiated heat is how a standard oven broils and how steam and hot water baseboard heat predominately work.

2) you generally should do NOT place a radiant barrier over the insulation that lies between and over the joists in a normal attic, especially in a region where the attic temperature can frequently reach condensation temperature (below about 45-50 degrees) - it may reflect back some of the house heat that is coming up from the house, but by destroying most of the temperature gradient from the house to the attic air destroys much of the driving force that moves moisture to the attic air and subsequent venting. Between that greater heat and the fact the barrier is also a moisture barrier, that makes a perfect condition for mold and rot in your insulation and attic wood, and has become quite an issue in energy upgraded homes because of retrofits that cut off airflow outside the insulation, but do not cut off the moisture source leaking thorough from the house. The proper and ONLY place for a vapor barrier in a normal attic insulation system is on the pressurized and normal warm, humid side of the insulation zone - directly above the ceiling drywall in the top floor, fastened to the UNDERSIDE of the ceiling joists or trusses, NOT anywhere above that. Perforated barriers are supposed to reduce this tendency, but the perforation area percentage is so small that typically they still act as a vapor varrier, just not a totally effective one.

3) radiant barriers reflect radiated heat ewith up to 99% efficiency but have basically zero resistance to CONDUCTION (body to body heat transfer at points of contact - think heat transfer from your warm hand to a frozen cold drink can, or hot pavement heat transfer to the bottom of your feet) - so there needs to be an air gap between the radiant barrier and the hot item passing the heat to it, otherwise the heat will just pass through it by conduction. Therefore, applying it directly to the sheathing (above or below) or manufacturing it directly on the surface of the sheathing defeats its purpose, even though this is commonly done.

4) there is a lot of discussion, particularly in the professional design community, about attic radiant heat barrier effectiveness and problems. Because they are being installed on the bottom of the sheathing or underside of roof joists, they act as a heat trap for the energy being conducted through the roof which would normally radiate into the attic air or be transferred by CONVECTION (fluid flow heat transfer) to the attic air, and be vented through roof vents, ridge vents, gable vents, etc. By trapping that heat, they are causing the underside of the shingles and particularly the felt and sheathing to get a lot hotter than they otherside would, essentially changing it from a system where the shingle top surface might reach 120-180 F and the inside surface of the sheathing about 80-140F in the summer, to making the entire roof system equal to the outside surface temperature. This causes more rapid shingle deterioration and cracking, and makes the felt or plastic moisture barrier under the shingles brittle and subject to failure.

Also, any moisture above the radiant barrier (from roof leaks or humid air coming into the area) is prevented from evaporating by the attic airflow which would normally remove it, so it starts acting like a steamer. I have seen both wood and metal lofts and attics become a major mold farm in months because of this effect, and a couple of roofs which started sagging due to rotted sheathing within 2 years of reroofing with tightly adhered radiant barrier. Some radiant barriers are vapor-permeable to reduce the moisture issue, many are not, but few actually are effective in letting moisture freely escape.

Having seen these products in use, and having analyzed and specified building products for use from the Middle East to the Arctic for decades, and having a Masters in Arctic Engineering (a degree predominately in energy conservation and heat flow), my personal opinion is that these radiant barriers will be banned by code within 10-15 years for unheated (so-called "cold" roofs) roofs, because they just do not use the principles of thermodynamics correctly. For more info on this issue Google the following search phrase  - moisture trapping by radiant attic barriers       and read the government (not the manufacturer) literature on the issue.

5) Unfortunately, the right way to handle this issue is to put the radiant surface on the OUTSIDE of the house - by using reflective materials on the roofing material. This is already done with flat roofs, house trailers, and industrial structures by spraying with alumiunum paint, and a few brands offer reflective aggregate shingles that are slightly more reflective and radiant than normal shingles. People obviously do not like this reflective surface from an aesthetic standpoint, though with solar cells coming into more general use this may soon be more widely adopted. The idea should be to keep the solar energy from penetrating into the building envelope at all, not try to re-reflect it away after it has penetrated throguh the roof system.

The sprayed-in foam has a couple of issues you need to be aware of:

6) it needs to be the low-pressure expanding type mixed for use around window frames, as fully expanding foam can bow joists or trusses and pop drywall ceilings free as it expands, and non-expanding foam actually shrinks as it cures, leaving gaps for air and heat flow alongside the ceiling joists.

7) being closed-cell it is essentially impervious to moisture, so the vapor barrier on the house side has to be EXCELLENT (incuding sealingof all penetrations), or it will trap household moisture escaping into the attic and promote mold and rot in the ceiling drywall and joists.

8) it tends to bleed chemical fumes into the house for a long period of time (can be noticeable for years), which may be objectionable to some people from an odor or environmental standpoint, and especially should be considered if any residents have severe allergy issues or respiratory problems.

9) I emphatically recommend AGAINST use of sprayed-in foam between ceiling joists or truss members in any area that can have cold attic air that could cause moisture condensation in the insulation, though this is probably not a significant problem where you live, assuming your Dallas is the city in Texas. For essentially year-around air-conditioned homes in hot climates, the problem can actually be condensation of attic air moisture on and in the colder ceiling surface insulation and on cold attic runs of air conditioned air, so attic ventilation becomes a critical issue to remove the moisture before it condenses.

In summary, having seen an awful lot of attic moisture and thermal problems, my personal recommendation would be to ensure excellent sealing of the house from the attic, use normal UNFACED fiberglass insulation, and instead of a radiant barrier ensure adequate full-attic ventilation. If you decide to got with a radiant barrier, then I would recommend a perforated one, sloping up towards the sides a foot or two and stopping a foot or so clear at the sides so moist air under it can escape to the roof joist spaces and be vented from the attic. I have seen this done several times with a fine nylon net strung above the insulation in the attic, supporting the barrier, resulting in something very similar to the double-roof system used in bedouin tents, where airflow between the two layers keep the hot air away from the living space.

A couple of comments about what Jim said:

1) Regarding type of insulation, in cold winter environments: Cellulose and fiberglass are actually about comparable in R value when installed - blown in cellulose runs from 3.2-3.8 R value, fiberglass batt 2.9-4.3 R value depending on manufacturer and whether hig-density or low density, high-efficiency or standard, according to official Department of Energy publications. Measured values in attic test cases, in areas with a true winter, after 10 years showed a decrease from 3.4 (in the test case) down to 2.1 for cellulose, and 3.5 to 3.3 for fiberglass batt, due to packing or matting. In an attic environment, there WILL be condensation or frost on the insulation at some point during the year (assuming an area with true winters) and in highly insulated houses commonly for a substantial time period each winter. Fiberglass packs down slightly from that weight but mostly rebounds, cellulose packs down and mats and does not substantially recover, so over the years cellulose loses 1/3 to close to 1/2 its insulation value, fiberglass about 10%.

2) a note on radiation barriers attached to the bottom of the rafters - there are a lot of installers and homeowners making two major mistakes with this product that can cause major trouble: First, be sure to terminate it short of the eave openings. I have seen cases where it was carried all the way out to the fascia board, thereby blocking all airflow on the underside of the roof. Even carrying it all the way to the eaves along the bottom of the rafters will block off ventilation to the main attic area. You have to leave the air space between the rafters open to full airflow from the soffit/eave area ot the ridge vent. Second, do NOT run it continuous from eave to eave across the full width of the attic - leave a gap about a foot wide under the ridge vents so warm and moist air in the attic can vent through the ridge vent. Closing the ridge vent area off with the radiant barrier effectively puts a vapor barrier around the main attic area, causing retention of the moisture which WILL accumulate there, promoting mold.

Steve made a good point.  Also, while it isn't required to remove the old insulation you can check the ductwork, wiring, etc. with the old stuff removed,  You can also spray foam around all openings and holes in wall top plates to better seal your home as Steve was pointing out.  My concern is the potential for mold spores you mentioned in your question.  If you suspect there are any get a good company in to remove the old and clean the attic.  Another concern is asbestos.  Your home is old enough you could have it in there and that's worse than mold if released into the air.

It's nice when things go better than expected. The salesperson had told us that it might be necessary to cut several holes in our ceiling in order to properly blow the insulation needed into all portions of our attic/crawl space. In fact, the service team handling this job was able to do it without any damage to ceilings. They were in and out of the house in less than three hours and the resulting warmer rooms were evident immediately.

I've tried calling, emailing, filling out online contact requests...you name it. These folks are either incapable of responding, are not able to respond, or don't care to respond. In short, they are not worthy of being noted with Angie's List.
I'm accustomed to long response times when dealing with a good company that is swamped with customer requests. I recognize that quality workmanship has a high demand. I have worked with a few skilled tradesmen that have reached out and explained their backlog and I have worked with them. This is not the case with these folks.
We're talking about either complete incompetence or just pure unprofessionalism, either of which would disqualify most contractors from even being listed as an option on Angie's List.
No phone call, no email, no letter...nothing...
If they can't even contact you to tell you that they're backlogged or swamped, then they don't deserve the credibility that Angie's List provides them. If they can't even communicate with potential customers that they are having trouble with staffing, equipment, office personnel, ANYTHING to explain their inability to respond to an inquiry, then they don't deserve to be on Angie's List.
I know that Angie's List has sales personnel calling these vendors to "SIGN UP" to be on their list, to be recognized as "above grade" contractors. So I'm of the mind that the only reason these folks are even showing up on Angie's List is because they're paying Angie's List to stay on.......that violates the very concept of this service.

The team showed up on time, and they were all very courteous. They paid attention to detail, and were extremly thorough, even getting insulation into a very tight spot that we didn't think they'd be able to reach. They were there for approximately 10 hours, and did a good job of cleaning up afterwards. I could feel a differnce in inside temperature right away. Just wish I had done it sooner!

First, let me say this is the third insulator on Angie's list in the space of less than a week and while the other two were rated more highly, their performance was so bad that I will have reservations about using Angie's list in the future to find a contractor or other help.
Dutch colonial, which have a fairly flat roof on top and over the
Washington Insulation Contractors Provider Name Locked
, followed by a very steep pitch downward to the gutters. These types or roofs are, apparently and according to my many Google searches, prone to ice dams. One or two roofers suggested installing an electric cord on the roof and turn it on when it snows. It was not an inexpensive fix and I have read, though not frequent, it is not without
Washington Insulation Contractors Provider Name Locked
.
I had my roof replaced with architectural asphalt shingles along with new gutters, down spouts etc. Until this winter, I never had a leak though on the few occasions it snowed, large icicles formed around the house, a sign that an ice dam had formed (ice that forms at the
Washington Insulation Contractors Provider Name Locked
of the roof and when snow behind it melts it has no where to go but under the shingles and into the house). The roofer suggested that I have the insulation checked if I continued to have problems which, this year, I did. There were minor leaks into the house during the very cold stretch when we had a small amount of snow and large icicles outside the house after the snowfall in March.
I called USA Insulation, one of the highest rated insulators on Angie's. The owner wanted to know how old the house was and looked at a picture of it on Google while we were speaking. He said with this type of house of this age (built 1957) he would not just do the crawl space but would require I have the entire house insulated which he felt was too much for me to spend if I was selling the house in a little over a year (my take, he did not want a relatively small job). He referred me to

Insulation, also highly reviewed on Angie's. A young man came out and was very pleasant but he looked at the insulation and told me it was in good shape and there was nothing further to do to improve it. I asked if he would write me a note and he said no because he might have missed something and then would be liable. I suggested he write "to the best of his ability" and that it was hard to see everything, as it was a crawl apace which would absolve him of liability but provide me with documentation that I had attempted to have it evaluated. He needed to check with his managers and I never heard back.

A friend than referred me to

(202-545-0024; 301-565-9350; 703-550-0035). I noted they were on Angie's list but while they had good ratings they were not as many or as favorable as the other two. I called and Mr.
Washington Insulation Contractors Provider Name Locked
came over the same day. He told me I had virtually no insulation under the roof. Pipes, electrical boxes, and area where mice and other small animals could enter were unprotected. He suggested doing the following:
1. Removing what little insulation was there which was, in any event, the wrong size. 2. Foam seal the exterior ceiling (around pipes, wires, ducts, electrical boxes, bath fans, and other holes and gaps. 3. Styro-Baffles installed along
Washington Insulation Contractors Provider Name Locked
to maintain airflow. 4. Bring attic insulation up to R-49 by adding 11" (R-38) cellulose fiber. 5.Staple R-38 batting to attic access door (to prevent any insulation from falling out and 6. Adding R-38 batting insulation around the access hole (to keep the door to the opening in place). Two very pleasant men came the next day and spent ~5.5 -6 hours fulfilling all aspects of the job. Though the crawl space was high up and I have problems with balance (and do not know too much about insulation) when they asked if I wanted to inspect the job I was curious so I said yes. As far as i could determine, they had done a very impressive job. Perhaps one of the nicer aspects was how pleased the man who seemed in charge of the project beamed with pleasure when I said I would like to see it as when I came down he told me with a very large small he like his customers to look at the job as takes a great deal of pride in his work. And he has very good reason to.
I am enormously please with the job that was done, the people I worked with, and the price they charge. I wish i had had this done 10 years earlier, it would have saved me a lot of money and a lot of headaches. My only question at this point is how I will be able to trust the information I find on Angie's list. It seems there should be some spot checking by professionals of jobs that are performed as anecdotal reviews are clearly not very useful. I have hear people mention that this service benefits the contractor more than the consumer and that may be the care.
