Basement Waterproofing Cost Factors

Basement waterproofing costs in Charlotte depend on factors such as the basement size, interior vs. exterior waterproofing, and the method used.

Basement Size

The cost to waterproof a basement falls between $3 and $9 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.

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 $2,725 on interior waterproofing services, while extensive exterior services will cost an average of $6,375.

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.

Basement Waterproofing Pro Costs

In addition to supplies and tools, you’ll need to budget for labor when waterproofing your basement—because this is not a DIY-friendly task for most homeowners. That means you’ll need to hire a basement waterproofing contractor in Charlotte.

Labor Costs

On average, hiring a basement waterproofing contractor costs around $180 an hour in Charlotte. Get at least three quotes from contractors to understand how long your specific project is estimated to take and how much you’ll be charged.

Permits

Not all basement waterproofing projects require permits, but if you need to do any exterior excavation, you’ll need to apply for Charlotte’s Commercial Zoning Review, which costs $300. Your local basement waterproofing contractor should take care of this process for you.

Does Basement Waterproofing Increase Home Value?

Yes, waterproofing your basement adds value to your home. You can expect a 30% ROI upon project completion. Being able to advertise a waterproof basement in your home listing can be a big selling point when you’re ready to move.

In the meantime, a waterproof basement may be worth the cost simply because it helps you avoid the high cost of water damage restoration and mold remediation.
