"They leveled our sagging floors beautifully and installed a drain system with a sump pump to address basement flooding issues. All was done with punctuality, precision, and professionalism. Additionally, the price was very reasonable especially compared to competitors. Highly recommend."

"It took two days to tear out the old insulation under the bottom floor and install encapsulation in the whole crawlspace. Nick and his crew did quality work getting the job completed. They also patched holes in the foundation, hauled off all the old, dirty insulation and torn vapor barrier. All-in-all a very accommodating crew."

"What a great experience! I had no hesitation hiring Josh and Sarah after meeting them and hearing their recommendations for remediation. I thought my problem was in the attic but after a thorough inspection, the issue was clearly in the crawl space. Josh, Sarah and crew were very thorough and efficient and took the time to go the extra mile to assess mid-stream to make additional adjustments. I am so pleased with the finished product. When another contractor compliments your work, that's saying something. Great job guys!"

I was extremely pleased with All Dry.  They gave me many options to fix my flooding basement problem without any high pressure sales techniques.  The crew did an awesome job and were very courteous.  I made a few changes as the install progressed and they handled everything with a smile.

There are a few companies that do the same type work and I have used 2 of them.  I would not hesitate to recommend All Dry.

Basement Waterproofing questions, answered by experts

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road.
