"First of all let me preface by saying that I purchased this home on foreclosure and it had been neglected for several years, including the gutters which is what" caused the leak in the foundation wall. Because the problem was allowed to continue for so long it had spread to all of the drywall in the basement. A-1 came in and removed the bottom two feet of drywall, vapor
, and insulation from all the exterior walls of my basement they also removed a few rotted spots of the framing and painted a couple small patches with a mold and mildew resistant paint. The whole process took approximately a week and the did an excellent job of cleaning up after themselves. After the crew left we noticed a couple patches of the block that still had mold stains on them, when I contacted them about this they came out again and painted the block in those spots. Maybe I am naive about this, but I think that it would have been
to paint all of the exposed studs and blocks to hopefully prevent any future issues. The workers that came to my house were barely out of high school, but they were professional although I don't know how experienced they were. Overall it was an unexpected expense so I am not happy about it, but they did an ok job. I still think they were a little overpriced, but I didn't have time to get multiple quotes.

Mold in a basement is a common problem. My company helps people with this every day. Some of the answers you received were helpful but not all the information is correct. First, you need to eliminate the two main ingrediants that mold needs to survive. The first one is water intrusion. This is a must. I am assuming you have no water intrusion as you make no mention. The second componant that needs to be eliminated is moisture. Moisture is also humidity. Basements need to be kept airtight in the summer months. Some folks have posted that you need air flow in your basement. Nothing could be furthur from the truth. When you open any windows for example, not one micron of air goes out of the basement, Warm humid air is sucked into the basement. Houses suck air into the basement and it meets the cool surfaces and skyrockets humidity. The windows must be kept closed and a dehumidification device installed to ensure humidity stays below 60% humidity. The dehumidifier should be energy star rated and purchasing a seperate humidity guage is a must to monitor the unit's progress. We like to keep our customer's basements at 50% humidity. This eliminates the smell that is active mold spore growth. Once the water and humidity is brought under control. Remove the organic materials that have mold on them. Walls, sheetrock and studs that have been affected. Follow the advice of previous posts as you must ensure that you do not affect the rest of the home. Once removed, install new walls using as much inorganic material as possible. We also install vapor barrier over the walls and seal the floors to stopwater vapor transmission into the basement. Poly plastic is not a acceptable vapor barrier. It is not "zero-perm" and will still allow moisture transmission. It will also crack and break into pieces over the years. A PVC liner rated "zero-perm" is the correct product in this application. Depending how large the basement is and if it is sectioned off will determine the dehumidifier strength. We use the Santa Fe line of dehidifiers as they are super energy efficiant and work like a dehumidifier on steriods. I hope this helps and I wish you the best in Basement Health!

Is the cabin conditioned year round or at all?

 

Are there any grading or moisture issues that are allowing bulk moisture into the crawl?

 

Conditioning the crawl is usually the best answer but if it is sporadic use and/or makes better sense to leave as a vented space, you need to do the following for optimum performance:

 

- Install a vapor barrier across the floor.  Seal all piers and penetrations as well as seal to the stem wall.

- Insulate the underside of the floor and ideally thermally break the floor joists from the earth.

- This is best accomplished by covering the floor joist with a rigid foam and sealing all the seams.

When you say vented to the roof, do you mean into the attic UNDER the roof, or through the roof with a duct up through a roof jack into a roof hood ? Hopefully the latter, otherwise you have the likely source of the problem.

You are clearly getting moisture in this area still, so more insulation will not help and may hurt - insulation does not stop moisture but does trap it, particularly if you add enough tht the freezing front moves well down into the insulation, so vapor coming up from the house freezes in the insulation (making it wet when it thaws) rather than venting into the attic and evaporating from there.

You need an expert check on the bathroom area - that the fan unit and any light fixtures are tighly sealed to the vapor barrier. Usually they are installed with about a 1/4-1/2 inch void all around for ease of installation, and not sealed at all, so moist bathroom air vents around themm into the attic.

Then the fan unit needs checking for openings - many have openings in the plastic or metal case from manufacturing that are not sealed but should be. Do NOT use any type of unit that, because of big lights or heat lamp, says it has to be vented and cannot be sealed in, because moist air goes right up through it.

Then the duct from the fan up through the roof needs checking for leaks (and should be insulated, at least if your attic goes below freezing ever), and should have a roof jack where it penetrates the attic - a rubber seal in a metal plate that fits tightly around the duct, so the air blown into the vent hood on the roof cannot circulate back down into the attic. Most installers just cut about a 1 foot opening in the roof (especially if they can install the duct that way without having to crawl around in itchy attic insulation), run the duct up through it into the roof hood, and walk away. That leaves that big opening in the roof sheathing for the wet air and condensation in the hood to corculate right back down into the attic. Some installers (like my house whenn I first bought it) really take the easy route and don't even connect the duct to the hood - they just terminate it a foot or so below the sheathing so ALL the moist air goes into the attic.

I would also check the kitchen and any other bathroom fans for the same leak sources or improper installation, and make sure all vent pipes are intact to above the roof, and that there are no furnace or HVAC ducts disconnected or damaged that could be adding moisture.

Also look around all roof penetrations for ducts and pipes for staining on the underside of the sheathing, which would be indicative of roof hood or jack leaks that should be repaired. (Hopefully, with a new roof you would not have any).

The area most affected should have the insulation moved away and checked to see if the vapor barrier has holes or tears, openings around pipes, ducts, light boxes or wiring, or was maybe totally torn out by some prior workman. If your vapor barrier is not effective, moist household air will move into the attic almost year around, but especially in cold weather, carrying moisture into the attic, where it will condense and cause mold.

Also - if you have a fireplace chase (wood boxout around metal chimney) in that area, it may connect to the house in the firebox area and be open to the attic (which is a real fire spread hazard but for some reason is not contrary to code), letting household air flow by that route.

The mold should be brushed and vacuumed away, then treated - there are commercial sprays that are fungicides that commercial mold and mildew removal contractors have, a sprayed chlorine bleach and borax solution has also been shown to work but you would have to have an air supplied respirator and chemical suit to work with that, which only professional remediation contractors have. Do NOT paint the area - especially the underside of the roof sheathing and trusses. They needs to be able to breathe, not have any moisture from above locked in.

Stains in the attic (assuming this is an unoccupied area) can be bleached, and then if you want the evidence to go away and make it easier to tell if there is new staining or mold, sanded to remove the worst of them.

Stains on areas visible from the outside like walls and rafters can be treated with Chlorine bleach (beware of dripping on good finishes below), painted with Kilz or similar anti-fungal primer, then painted. Stains on the underside of the sheathing visible in the soffit area can be bleached and then when dry, sanded away.

Ventilation is essential, but without removing the source of most the moisture you will not win this war no matter how many times you battle it.

While I would guess the fans and vents are the problem, is there anything different about the attic ventilation to this area versus the other parts of the roof - soffit covers, blocked eave openings, insulation-clogged bug screening or soffit cover openings, lack of air chutes or eave baffles, insulation pushed up against eave opening or up against roof, horizontal blocking that prevents or obstructs airflow, no ridge vent above it, etc ?

If you are not able to find an obvious source of the moisture, I woud consider getting a thermal IR scan of the attic. For typically about $200-300 an energy conservation expert with thermal scanner can scan the attic (might have to be done at night or VERY early morning if done in summertime, to accentuate the temp difference between house air and attic air, unless you have AC in which case turning the AC down low and blower on full can work by pushing cold air rather than hot up through any gaps or voids. If you have that done, check on price to add in the rest of the house too - probably not more than about $100 more, and can show you where your air leaks and poor insulation air. You should try to get one who can provide the entire scan to you on CD or DVD, so you can review it in the future. Here is a link to some images so you know what I am talking about -

Call in the professionals.

There is no sense addressing the mold issue until you resolve the basement leaks.

High ground water that is seeping into your basement is going to lead to long term, serious damage to your foundation and basement walls.  Any mold you remove will just keep coming back.  The first question is the age of the home and whether or not you have working perimeter drain tile installed.  If you home is pretty old (30+ years) it is possible you do not have a drainiage system, or the system is clogged / deteriorated beyond function.  For a newer home, perimeter drain tile was a requirement, but doesn't mean it was installed properly.

I recommend you hire a licensed architect to review your house's construction, the site and look for indications that a drainage system is in place and functioning.  They should be able to find out where the drain comes out, and to check it (after a rain or by doing a water test) to see if it is working.  If it is working, it is possible your system is undersized or only failing in a specific area.  It is also possible a second, lower water table exists that is below your current drain system.  A site change, to change the current flow of ground water or above ground water may resolve your issue as well.  Something as simple as a new drainage ditch, retention pond or higher grades around your building may resolve your issue.

Working with a professional will prevent you from worrying about a 'draingage expert' recommending a high cost repair when another option may be available.

Some drainage people will propose installing a new perimiter drain inside your basement walls.  This system gets the water that gets through the walls and under the floor, and carries it back out.  This is a last ditch idea.  The best method, to solve the issue for good, is to dig back down to your footers, repair the waterproofing on the wall, then place drainage board over it (this protects the waterproofing while allowing moisture a travel path to your drain tile).  Then place gravel fill with geo-fabric over it, then backfill.  Now, no matter how much water you have in your ground, it will be directed away from your basement.

A sump pump in the basement to handle flooding or low water tables below your basement slab will augment this system.

Once you have the moisture issue resolved, then worry about stopping mold.  In the interim, any materials that are growing mold need to be removed (use protective measures).  Make sure you run a dehumidifier at all times and keep air moving by turning on the basement hvac vents or putting some fans in the area.

Working with a licensed architect will help ensure you pinpoint the exact problem, and have a knowledgable person to discuss the options with before doing any costly work.  The architect will also be able to assist with finding contractors and overseeing that the work is installed correctly (It is worthless to redo the drainage if any one area is not done correctly).  Good luck.

Olympic did a great job. They were very helpful and patient as our project took a long time (not because of Olympic - for other reasons). The price was very reasonable as well. Hopefully we won't ever have a need for mold remediation services again, but if we do, we will be sure to call them.

The job went well. The PM offered advice and explained things as they went along. He was most helpful with the insurance investigator who came to review our claim and see the remediation work and the beginning of the renovation work. Any time there was something we questioned about the work going on, the PM and/or crew was patient in answering these questions. If we noticed something we didn't like the look of in the work, the PM either explained why something was required to be done a certain way or would listen to our comments and make the changes we asked for. When the tile job in the shower first started, they had put down 2 large 2'x2' pieces when we decided we wanted the tile laid in a different pattern. The person laying the tile never complained and pulled up the tile already down and relaid them in the direction we liked better. We also changed from a full bench in the shower stall to two corner benches. They again made the change with no question and never showed any frustration with us. When we decided to use a block window in our shower instead of replacing our broken out window with a regular window that would need to be covered with privacy film, the PM realized our opening for the window wasn't a standard size opening and changing the opening size was not an option. Rather than tell us we couldn't have what we wanted, our PM took it upon himself to actually make a block window for us on his own time that fit our special sized opening. It looks great and he even matched the grill pattern on our other windows in the bathroom with the block sizes he used so our windows would have a consistent look. The work was slow due to special order items, but when the crew got to a point where they were waiting on something, they moved to another task within our project. They were never still. They showed up between 7:30 and 8:00 every morning and worked until 3:00 with only a short lunch break. They laid down brown paper and/or drop cloths on the path to their work area. They cleaned up their work area at the end of every day and pulled up the paper and/or drop cloth. We had a trip we had planned and paid for that fell in the middle of the job. The PM worked with us to ensure we didn't miss a moment of the vacation. There was also a point in our job that the crew had done all they could before our special order tile arrived (our fault since we had our heart set on something that wasn't available in-stock). We were told of the delay the Wednesday prior. The PM worked with the tile shop to put a rush on the order at no additional cost to us. He did reassign our team to another job site while we waited, but with the help of the PM, it was only 2 or 3 days instead of the 10 business days the tile shop told us to expect. The only negative I can say is that in this last job, 4 tiles had pencil

because the tile was sealed, we called and were told they would send someone out. We were asked if this could wait until someone was in our area since we live on the outer

He also gave me lots of feedback and general information on what to do next, what needed to be fixed.

We recently had water damage in our house for a second time in less than a year. With young children including a
Alton Mold Removal Experts Provider Name Locked
, I was concerned about the air quality. While there was no visible mold, I wanted to be sure that we didn't have mold spores circulating through the house.
My first point of contact was a woman in the front office (
Alton Mold Removal Experts Provider Name Locked
I think) While I don't believe she does testing herself, she was very knowledgeable and advised me to hold off on testing until we had completed the work we had planned to resolve the water issues. She also advised me on ways to minimize chances of mold developing in the meantime. It was a very pleasant and informative interaction. I got off the phone knowing exactly what they would do if I hired them and precisely the cost in addition to her recommendations for what to do while we waited for mold testing.
Once we had the work scheduled to resolve our water issue I immediately called back to schedule the air quality testing. My next interaction was with the inspector. He arrived on time and was completely professional. He explained his process and how the results would be presented very thoroughly. He gave an estimate on when to expect the result and his contact information should we have any questions.
The work was just performed and we expect the results in the next couple of days. Should there any issues with the results (when and how they're presented and/or explained), I'll update this review. However, given the service we've received thus far, I don't expect I'll need to make an update. As of now, I would highly recommend the company. I rated the price as an "A" because it seemed on par with other providers that I researched. However, to be completely fair, I did not get estimates from other companies. I was so impressed with my initial contact with this company I didn't feel compelled to do so.

spent almost 4 hours inspecting a home my husband and I have an accepted offer on. He answered all our questions throughout the inspection. He took his time and went over all areas of the home several times to make sure he did not miss anything. The report we received the next day was extremely detailed and very clear. His suggestions and thoughts were presented in a clear and easy to understand manner. He took a lot of photos throughout the inspection and included both photos and diagrams in his final report to illustrate any areas of concern. We fully understand all the issues this home has and feel very informed as we move forward in the home buying process.
