Basement Waterproofing Cost Factors 

With no two basements in Atlanta being exactly the same, the local waterproofing pros in Atlanta, GA you hire will carefully examine your basement to get a read on the project's scope. During a consultation, a waterproofing contractor can offer suggestions for how to waterproof your basement based on your home's construction, your property's slope, existing signs of basement water damage, and the specific risks for water intrusion that exist based on your home's orientation. They'll also use your input and desired outcome to design waterproofing plans. 

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.

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.
