Insulation reviews in Washington


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.

It went very well. They showed up exactly when they said they would and it took exactly as much time as they said it would and cleaned up completely afterwards. The insulation made the third floor cooler and solved the drippy HVAC problem we had due to an uninsulated unit. I would recommend them for anyone looking to get better insulation. They were responsive and pleasant to deal with.

I called
Washington Insulation Contractors Provider Name Locked
to set up an appointment for their staff to come to my house and give me an estimate for attic insulation. Because of my work schedule and their availability, I set up an appointment for three weeks later (

19). However, I called a week later and the representative told me that they could come earlier on
Washington Insulation Contractors Provider Name Locked
10. Although it meant having to take off from work earlier, I agreed and set up the appointment. On the day of the appointment, I called to ask around what time they would be coming to my house. Good thing I called as I wasn't even on the schedule, even though I had spoken to the same representative both times. He apologized for the mistake and said that I was on the schedule for the original appointment date of
Washington Insulation Contractors Provider Name Locked
19. That was three days ago, and I'm still waiting for them to show up. I understand that mistakes are made and agreed to the rescheduled appointment after the representative apologized. However, not showing up or calling, particularly after the first incident, indicates a lack of responsiveness and poor customer service.

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.

, was very responsive from the beginning to the end of the process. He came out for a free estimate and quickly arranged for his crew to come out to perform the actual work. The crew, including foreman,

was our contact, conducted the audit and the follow up consultations.
He dedicated a fair amount of time to conduct the edit and walk me through what was happening and what the various steps he was taking were designed to do, as well as real-time feedback as he was conducting it.
It took a few days for
Washington Insulation Contractors Provider Name Locked
to get back to us after the initial online contact, but once we connected,
Washington Insulation Contractors Provider Name Locked
was outstanding--very responsive, willing to work with me to find a time that worked for the audit, and even managed to do a last minute rescheduling so we could beat the snow blizzard.
The subsequent scope of work estimate was thorough, detailed, and very specific, broken down by item and the cost of those items.
We have not moved forward with the repairs, as the job is more significant than we had anticipated before conducting the audit. We knew we had problems, but had no idea what was going on behind the walls, Sigh. The result of a terrible, previous contractor.
Given the amount of the job, we feel we probably need to get another quote just for comparison. But we may just end up going with

was just outstanding and assured us

(and him) would oversee the project from A-Z, and the crew performing it is an in-house crew. After our last experience, that is an important detail.

I've tried calling, emailing, filling out online contact 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
Washington Insulation Contractors Provider Name Locked
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
Washington Insulation Contractors Provider Name Locked
(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. Had i not gotten the 3rd recommendation, i would be dealing with roofer to install ice shield (pieces of metal best installed at the time of a new roof that are placed two to three shingles in and exten outside of the roof or
Washington Insulation Contractors Provider Name Locked
and inhibit the formation of ice dams. Apparently, the are used frequently further north where there is more cold and snow. It would like have been expensive as my roof is new and shingle would have had to be removed and new ones installed. In fact, i have a few appointment to

came out for the estimate and we could tell he really knew his stuff. He gave a fair price for quite a bit of work and wrote a detailed quote/contract. We paid the deposit and his crew of two people came out. His crew was incredibly nice and WOW did they work hard. The crawl space was very difficult to move in and they really went after it. They stayed late and let me check things and point out a few spots I wanted some more foam.
After the job i noticed some cold air was blowing out a hole in the upstairs wall above the crawl space (we had a burst pipe which was why we needed the new insulation).

came out at no charge and worked for 3 hours sealing every little hole we could find.
