"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 have an old house with part crawlspace and part basement. So, it didn't fit the waterproofing "system" some of the other companies wanted to sell me. Kyle suggested a fix that fit the specific water intrusion problem for my old house, and replaced the sump pump. This cost far less than rebuilding my basement to fit a "system". Crossroads Foundation Repair's communication and recordkeeping is very clear and professional. I would recommend this company without hesitation."

"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

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

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.
