"Weather-Tite was recommended to me by a contractor who I trust to evaluate and repair water and moisture issues that I was having in my garage. Bob and his crew did a phenomenal job!! My husband and I are beyond thrilled with the results! They are professional, courteous, and fastidious. Half of my garage is underground, as there is a hill in my front yard leading up to the house. The repair involved excavating dirt along the front of my house next to the garage foundation wall down to the drain pipe, repairing cracks and holes, applying waterproofing and more. The interior wall was cleaned and drylock masonry paint was applied. My landscaping on the outside had to be removed and then put back. They did such a good job that you couldn't even tell it had been moved at all. We also had Bob and his crew complete a second job for us. This involved excavating another trench but in the back of the house along 16 feet of the foundation, replacing a drain pipe and waterproofing. They were at our house for three days. During that time and after we had torrential rain and everything stayed dry!!! I highly recommend Weather-Tite Waterproofing, Inc.!"

"Had a Sump Pump and French Drain installed, Mold Removal and a major repair to a foundation wall. Absolute Waterproofing and Renovations were highly recommended to me by a gentleman that does business with them everyday. Lou and his guys came when he said they would, finished when they said they would. They protected my house from dust and dirt by covering everything with plastic. The price was the most reasonable in comparison. They were professional, clean and trustworthy. They actually found a gold wedding band that was missing for months and were honest enough to return it to us. I'm 100% satisfied with the the work that was done and highly recommend them!"

"They explained their system and the installation process in detail. They were very flexible and worked with our schedule to finish installation of French drain system before sale of house. Extra foundation work was needed, and they did that as fast as possible"

"I can't say enough good things about American A-1 Waterproofing. Roland and his team were amazing. I had originally opted to go with another contractor to install a French drain and sump pump, but after exposing the foundation, they got spooked and said they wouldn't perform the work. Roland came by and assured me his team could get the work done and they did not disappoint. Through the initial estimate, permitting, construction and final sign off, Roland and his team were communicative, prompt, clean, and extremely professional. It was an absolute pleasure to work with them!"

"Alec was professional and explained what needed to be done to clear the lavatory drain with an electric snake. He installed new angle stop for lavatory. He supplied and installed two supply lines for the faucet. The old valves were rusty and did not work like they used to. Alec said the old valves could leak in the future, and we did not want that to happen. They arrived on time and continued working until the job was complete."

"I had a great experience with this company installing my new boiler. Their pricing was fair compared to other estimates I received. Dave walked me through the entire process and answered all my questions, and his team came in and did a great job with the installation. With so many scammers out there, I truly felt comfortable working with this company and will absolutely use them again in the future."

Foundation Drain Installation FAQs, answered by experts

Costs depend on pump type, labor, and site-specific requirements like excavation or drainage lines.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

The type of stormwater drainage system you need depends on your area’s storm severity and frequency. Your property’s location should also be considered, including the surrounding soil type, nearest roads, existing drainage systems, and slopes and hills. Your property’s structure, such as decks, walkways, crawl spaces, and foundation, also affects what drainage system will work the best.

Yes, professionals ensure proper grading and drainage to prevent water pooling.
