Breakdown of Costs

Exterior Waterproofing Cost: Prices range from $70 – $350 per linear foot. This method is the most effective strategy to keep water from infiltrating your home. It requires substantial excavation to expose the foundation, repair the crack, and waterproof the area.

Interior Waterproofing Cost: Typically costs between $65 – $130 per linear foot. This is a suitable option if the problem is inside the home and cannot be addressed from the outside. We ensure a drainage system is installed inside the basement to keep water away from the foundation.

Foundation Repair Cost: Depending on the severity of damage, the cost of foundation repair usually falls between $3000 – $9500.

Sump Pump Installation Cost: To lead water away from your basement effectively, we provide sump pump installation and replacement services. Costs vary based on the sump pump model and location, ranging from $650 to $3600.

Window Well Installation Cost: This service, crucial for preventing water accumulation around basement windows, costs between $80 – $350, depending on size and project complexity.

Mold Removal Cost: Removal of mould, often left undetected until late stages, can cost anywhere from $2000 – $150,000. The price varies depending upon the severity of the mould infestation.

Crawl Space Encapsulation Cost: Installing an air-tight vapor barrier system and a dehumidifier in the crawl space can decrease moisture levels and reduce the risk of mould, costing on average $10 per square foot.

Internal Crack Repair Cost: Cracks can materialize in your basement’s concrete floors and walls and are repaired using hydraulic cement or epoxy injection methods. Prices fall anywhere from $75 to $750 depending upon the size of the crack.
