"ErieHome waterproofed my basement. The crew was polite, kind, and came in, did an excellent job in 3 days by digging a trench on the inside of the basement, removing the dirt from the bottom of the foundation, installed corrugated tubing, rock and then cement. They also installed a Humidex airpurifier and new sump pump with a backup pump. They cleaned up afterward. Any questions I had were answered in a respectful manor. I now have peace of mind knowing that I no longer have to monitor weather forecasts for rain or have to clean up anymore incoming water. The system is warranted for the life of the house and included within the price, which increased the value of my home."

"I hired them to repair a crack in my basement wall that had a small leak. They were very professional. They filled the crack with foam injections and backed their work with a 5-year transferrable warranty. I had discussed this with other companies that wanted to charge me thousands of dollars and dig up my foundation for a little crack. These guys were good, quick, efficient and helpful. They gave me other tips for finishing my basement while they were there. Overall it was a great experience and I highly recommend them."

"We had a challenging project with water removal and structural support issues. Our crew of Tim (Foreman), Marq, Jayshawn, and Devon worked diligently to install a new drainage system and support beam for the house, spending late nights to get the job done. Thanks to (Manager) Cornell for his assistance on this complex project. Matt E"

"We had a basement that always had water in it almost year round. We decided to sell the house and move to North Carolina. Still trying to sell the home we decided to have a French Drain System put in with a bleeder line, as it would not sell as it was. The Stay Dry team was excellent from start to finish. Their team was professional and was accommodating to the fact that we needed to keep the home clean due to selling it and took extra steps to ensure no contamination spread to the rest of the house. After the job was done I have had zero issues with water and we are closing on our home today. Thank you so much for your hard work and courtesy Stay Dry! Pictures below are just after washing and cleaning. It appears wet but was completely dry the next day."

Basement Waterproofing questions, answered by experts

Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

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.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.
