"The entire waterproofing job was done in 5 days, Monday to Friday. There was a lot of work that needed to be done and it was quite extensive. All work was done according to the original quote plus there was an additional work that needed to be done that was not picked up by the original quote. We had expected some unforeseen "surprises" due to the horrible condition of the basement walls and knew in advance that this may happen. (and it did) Aside from that, everything was done according to contract and a few extra things were done that we were not charged extra for. That was a very nice gesture on the part of Stay Dry Waterproofing. We would highly recommend using Stay Dry Waterproofing to fix up your basement issues. Pictures submitted here only show one side of the basement. The entire perimeter of the basement was worked on and waterproofed."

"We just had Jayson Wright, Service Manager, to our residence to do an inspection of our egress window and a potential water issue on one of the basement walls. Jayson did an excellent job and explained everything that we were concerned about. I fully recommend Jayson Wright and Groundworks for any and all basement issues involving waterproofing."

"Mid-State Basement Systems came highly recommended by a good friend from Buffalo, NY and they did not disappoint. From start to finish they were very professional yet personable. Larry & Phil in the initial stages of the basement inspection and a reasonable quote. Silvino and his team who done the actual work was incredible, done with absolute excellence. They were here when they said they would be and finished the job a day ahead of schedule. I am thoroughly pleased with this company, first class. I highly recommend them if you need work done on your basement.******"

"Some of the negative problems a mess was left big chuncks of concrete under my furniture some stuff wasn't covered properly. Something very sentimental to me got broke i got told 'm sorry that happened they were told to becareful due to breakable items. They offered to come back & clean up all the mess that was left & fix some other issues. The two guys who came back for my concerns were very nice & respectful & addressed & fixed the issues. The installation team was very friendly as well but was the ones that left the mess & broke a item of mine I've had for 10 yrs. So very heart broke over that. Now just waiting to see how my basement holds up when it rains heavey or for days at a time."

Basement Waterproofing questions, answered by experts

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

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.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.
