"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."

"I had OBA install outdoor french drains and new downspouts a couple of years before they waterproofed my basement. They were the only company I could find who did it all. Basement waterproofing included removing old, putting in new: full inside perimeter drainage, enlarge sump pit, 2 sump pumps, I-beams and carbon fiber straps. Added in brand new: battery backup for sump and vapor barrier on most affected wall. When my basement got wet a year later after the work was done, they didn't hesitate to schedule someone to inspect. If was heavy condensation, barely a thin puddle compared to 2 inches of flowing water. They had to rework a 6 ft section and add cement around the I-beams, each on their own call outs. They didn't charge because I have a lifetime warranty, transferable to the next owner. I'll be working with them again soon for a professional level dehumidifier."

"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

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

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.
