"It took a long time to get this scheduled because of poor communication. There were multiple times that I was told I would be emailed with either a quote or a schedule date, and I" had to call after several days of not receiving the email. When I did finally get them scheduled to come out, they did not show up at the time agreed on. When I called, the person I talked to sounded like he had no idea there was work scheduled to be done. However, he did send somebody out within the next hour or so, and I was not displeased with the work done. I was also frustrated that I was promised a 2-year warranty on the services provided, but never received any paperwork on that.

"I had a wonderful experience using
. We had a leak in our bathroom shower a few years ago. It was fixed but I was always suspicious about having a mold issue" afterward. I finally decided to have it inspected and called
at 7:30 on a Monday morning. He was at my house at 10:00 the same morning. He used a camera to look behind the tub and shower and found no mold. He was very honest and didn't charge me for the inspection. Mold is a scary thing and we were thinking the worst. We REALLY appreciate
's honesty and integrity! We would use this company again and would highly recommend it to anyone!

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.

came to our home this morning to analyze a mold situation in our kitchen. Our dishwasher had a slow leak that had caused mold to grow underneath the cabinets. Some of it is visible on particleboard bottom of a lower cabinet. Knowing that we'd be renovating our kitchen in a few years and that the mold is dormant and mostly contained behind/beneath the cabinets,

They provided excellent, professional, courteous service (all the things one would hope for) in a difficult situation. As the homeowner, I could not see the extent of the damage & repairs under the home, so confidence in their work was important. I feel very confident it was done well.

It has been excellent. They built a plastic containment area in the basement so the mold would not spread. They covered everything with plastic. They put down a runway of plastic and cardboard. They put ply-wall over the basement window with a tube to blow the dirty moldy air out the hole without getting into the room. They are A plus quality. Another company quoted $2000. My insurance agent recommend them. They were on time and professional. One day when they were getting ready to leave, they didn't try to find me but they walked out the basement door and went to the front door and rang the doorbell. I would definitely recommend them.

The inspector was very through (inspection took 3 hours). He discussed what he was looking for and why. He took picture and asked questions throughout the house. He suggested that we take a sample of mold growing on the wall along with the airborne samples. (Good thing I took his advise) The scraped sample turned out to be Stachybotrys. We decided that we did not want the house because the cleanup would be too expensive and is never a sure thing. When I asked him to recommended a company for cleanup he told me that it would be a conflict of interest to tell me. Very professional.ett
