Licensed Waterproofing in Edmond, OK

The most common causes are poor exterior drainage (grading that slopes toward the foundation), clogged or missing gutters and downspouts, hydrostatic pressure from a high water table, foundation cracks, failed or missing waterproofing membranes, and condensation. Most basement water issues involve multiple contributing factors that need to be addressed together for effective resolution.

Exterior waterproofing involves excavating around the foundation to apply waterproof membranes and install drain tile at the footing level. It stops water before it enters. Interior waterproofing manages water that has already entered by collecting it with interior drains and routing it to a sump pump. Exterior is more effective but significantly more expensive and disruptive. Many projects use a combination approach.

Costs vary widely. Interior drainage and sump pump systems typically range from several thousand to ten thousand dollars. Exterior foundation waterproofing for a full perimeter can cost fifteen to thirty thousand dollars due to excavation requirements. Crawl space encapsulation typically costs five to fifteen thousand dollars. Minor crack repairs may cost several hundred dollars each.

Crawl space encapsulation involves sealing the crawl space floor and walls with heavy-duty vapor barriers, sealing vents, insulating walls, installing drainage if needed, and adding a dehumidifier. This converts a damp, vented crawl space into a dry, conditioned space that eliminates moisture problems, improves indoor air quality, and can reduce energy costs by 15 to 20 percent.

Yes. A dry basement or crawl space with a professional waterproofing system adds usable square footage and eliminates a major buyer concern. Homes with documented waterproofing systems and transferable warranties sell more easily and for higher prices. Conversely, evidence of water damage or active moisture problems is one of the most common deal-breakers in real estate transactions.
