"Chris and his crew did what they said they would do, when they said they would do it, and in a way that left me 100% confident that the mold was gone. Chris stayed in touch with me every step of the way and explained, in laymanâ s terms, what had been found and what he and the crew would do about it! I strongly recommend the Clean Air Crew."

"Ross and his team did an AMAZING job waterproofing my basement! I was worried about the process because my basement is finished but they walked me through it all and left my home ready for the next rains! I highly recommend this company! They will be doing some foundation repairs for me here in the near future as well!! Canâ t wait to work with them again!"

"Kim and their crew did a great job. Kim listened to our concerns and came up with the proposal. She was available to answer any questions we had before making a decision. They started the work immediately and finished right away. We have not had any heavy rain since the work was done, so we do not know if it fixed our problem or needed modifications. That remains to be seen."

"Bought this in the spring to use before burning in the fall/winter.  Ended up moving in December and did not use it.
I'm wasn't sure how to score a company I didn't use (and not reviewing isn't really an option), so I just picked a score consistent with the average rating.

Basement Waterproofing questions, answered by experts

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.
