"They came out promptly and discussed the situation. They had a few suggested approaches, but they seemed a bit ad-hoc, although they would probably work. Finally quoted a significant" excavation job, concrete pour, and support pier replacement. Nothing wrong with this but it was more expensive than other quotes. Took some time (a few weeks) and a reminder call before they got back to me with the final quote after the initial visit. I did discuss some other drainage issues around the house and they gave some helpful and honest advice.

It’s easy to do, but forgetting your crawl space can have plenty of negative consequences for the rest of your home from poor air quality to high energy bills.

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!

Where is the home located, what is the exterior wall construction and type, how is the space heated?

 

It could be a whole host of different scenarios that would generate that result.  It is nearly impossible to tell but I would say that most basement moisture problems are a result of bulk moisture intrusion or condensation issues. 

 

Given the deep and hard winter this year, it could be a condensation issue that hadn't previously been shown.

This is a great family-run business. I feel like these guys have fair pricing and do good work, both of which seem to be a rarity among foundation contractors. I always recommend them whenever someone says they're having foundation problems.

Excellent job! I could barely even tell that they had dug a big trench through my yard that day- took great care in placing the dirt/did to the side and put it all back in place. Took care in the house to not track mud. Nice guys too.

personnel were efficient and accurate in assessing the situation to start with. Two other contractors and one pest control company also assessed the situation and missed what

was the only company that was accurate in their assessment. Their price was reasonable. The workmen were efficient and professional. They placed tarps to prevent tracking dirt through the house. They were appropriately suited up to go into the crawlspace. They brought out more than 10 large garbage bags of debris! The pest control company that quoted for "pest mitigation and debris cleanout" didn't even recognize the piles of pine

It went great.

and all of his employees were incredibly fair, nice, honest, and non-alarmists. They did not try to talk us into doing more than was necessary and saved us a lot of money. The work was done incredibly fast and well. They cleaned up after themselves better than any other contractor we have had. We would use them in the future for sure!

When I discovered mold and water damage in my garage and basement, I first contacted a specialist to remove the damaged sheetrock and carpet; then I had to find someone to mitigate the damage. I had no idea what was causing the water damage. The first two firms I called were going to charge me nearly $10,000 for a package of remedies, including water guards, special basement walls, a sump pump and de-humidifier. A third contractor recommended, for $7500, that he dig a trench outside the house and waterproof the foundation. Given the conflicting information, I decided to contact one more waterproofing specialist. That was when I contacted

was the only person who took the time and effort to figure out the source of the problem--a broken pipe from a faucet outside the house which was rarely used, and which is why it had gone undetected. He came to my house 3 times (and sent another worker once) to figure it out, and did not try to sell me anything. In fact, he didn't get a single dime for his efforts since a plumber was needed--the plumbing bill was $468.22. The only thing

and his crew did a great job at a very reasonable price.
We had an upper story added to our house during an extensive remodel in 1995. We had cut into an existing concrete retaining wall to create a garbage can area and support for a new front porch. The new porch foundation and wall began to separate a few years ago and then recently got much worse. I had 5 or 6 contractors take a look at it. Bids were very high. None of the solutions completely addressed the issue. We had almost given up but we worried that the wall was either going to collapse or the porch was going to start sagging. We were scheduled to move for an overseas posting within the next few weeks for the next 18 months. I was worried something catastrophic was going to happen in our absence. I was having nightmares about it.

had a decisive plan on the spot. He had full confidence that he could fix the problem once and for all. This is not the feedback I got from the other contractors.
He and

in the office accommodated our rushed schedule. The crew was always punctual and cleaned up nightly from what was a very messy project.

was on site several times a day to check on progress. He is very pleasant to talk to and always available for questions. During the demo he pointed out the previous cinder block portion of the wall had been filled with dirt and not concrete the engineering had called for. I had permits and everything. It was a horrible job. I had even talked to the contractor who did the original work. I am so happy I didn't pay him a second time for such poor work.
The replacement wall section will outlast the house! It is solid concrete with plenty of rebar. They slurried the old and new wall surfaces together. Cosmetically, the wall never looked this good. His men also did a beautiful job replacing all of the trim that had to be removed to gain access to the structural posts. They even caulked and painted. I was expecting to have to do that myself. This is one of the few times a contractor didn't leave me with a to do list after they were finished. I greatly appreciate that.
The temporary support posts needed to stay in place while the concrete cured. We had already left and was concerned they would be there for a long time.

came the next week and removed them as promised.
I will use

again when we return. I don't say that very often. Luckily, the biggest project on our list turned out to be the easiest contract of them all!
