"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.******"

"They did a fantastic job waterproofing our basement! Our basement is totally dry now, no more leaking around the foundation. They also were able to move our sump pump to a better location. I highly recommend Seagate roofing and waterproofing."

"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

To maintain an outdoor structure, perform regular inspections for damage, leaks, and weak joints. Clean the structure regularly, treat or repaint wood surfaces for weather resistance, and reinforce any weak joints to prevent deterioration and ensure its longevity.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.
