Basement Waterproofing Cost Factors
Basement waterproofing contractors in Minneapolis look at factors like basement size, signs of basement water damage that are already present, your home's orientation, and your budget when making suggestions.
Basement Size
The cost to waterproof a basement falls between $3 and $10 per square foot on average, although where in this range your pricing falls depends largely on the type of waterproofing method you choose. In any case, large spaces require more time, labor, and material to waterproof than small spaces. Therefore, the larger your basement, the more you can expect to pay for waterproofing for any given method.
Below is a breakdown of how much you might spend for a range of basement sizes.
| Basement Size (Sq. Ft.) | Average Cost Range |
|---|---|
| 300 | $600–$1,800 |
| 500 | $1,000–$3,000 |
| 700 | $1,400–$4,200 |
| 900 | $1,800–$5,400 |
| 1,000 | $2,000–$6,000 |
| 1,200 | $2,400–$7,200 |
| 1,500 | $3,000–$9,000 |
| 1,700 | $3,400–$10,200 |
Interior vs. Exterior Waterproofing
Depending on where your basement water issues are stemming from and what solutions your expert recommends, you may need either interior or exterior waterproofing services. Some homes require both. Interior basement waterproofing is often more affordable because it doesn’t involve excavation and backfilling. Something like installing damp-proofing around the exterior of your foundation would require a lot of digging, which drastically increases labor costs.
You’ll spend an average of $3,000 on interior waterproofing services, while extensive exterior services will cost an average of $7,000.
Waterproofing Method
As mentioned above, professionals can waterproof your basement from the exterior or the interior. Exterior methods are more effective because they’re preventative, but they’re also more expensive because they tend to require excavation, which is time-consuming. The table below includes a list of basement waterproofing methods along with cost ranges for each.
| Waterproofing Method | Interior or Exterior | Average Cost Range |
|---|---|---|
| Sump pump | Interior | $500–$1,100 |
| French drain | Exterior | $9–$95 per linear foot |
| Subfloor drain tile system | Interior | $25–$55 |
| Dehumidifiers | Interior | $400–$850 each |
| Vapor barrier | Interior | $700–$1,700 |
| Weeping tiles (interior French drain) | Interior | $50–$80 per square foot |
| Baseboard channels | Interior | $22–$23 per linear foot |
| Yard grading | Exterior | $1,250–$2,000 |
| Underground downspout | Exterior | $150–$1,200 |
| Gutter system | Exterior | $3–$28 per linear foot |
| Liquid membrane waterproofing | Exterior | $1.50–$4 per square foot |
