"I recently had the pleasure of working with Stay Dry Waterproofing and I can confidently say that they are the best waterproofing company in town. From start to finish, their team of experts were professional, knowledgeable, and attentive to my needs. The project manager, Brock, was fantastic to work with. He took the time to thoroughly explain the waterproofing process and answered all of my questions with patience and expertise. He also provided a detailed timeline for the project, which helped me plan accordingly. The installation crew arrived on time and worked diligently to complete the project on schedule. They were respectful of my property, kept the work area clean, and were mindful of noise levels. Overall, I was extremely satisfied with the quality of work and level of service provided by Stay Dry Waterproofing. My basement is now completely dry and I have peace of mind knowing that my home is protected from water damage. I highly recommend this company to anyone in need of waterproofing services. They truly deserve 5 stars!"

"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 FAQs, answered by experts

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.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn’t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a flood wall around the house if you live in a flood-prone area.
