"Weep holes” are drilled into any concrete blocks and the company's “Rigid Sealer,” a waterproofing membrane, is placed onto interior walls as needed.

Frequently Asked Questions
What Are the Best Methods of Basement Waterproofing?
The best method of basement waterproofing is largely dependent on your home and the severity of your moisture problem. There are many options when it comes to waterproofing the bottom level of your home, and most basement waterproofing companies will be able to recommend the best fit after an in-home consultation. The most common outdoor basement waterproofing methods are optimizing soil grade, installing new drainage systems, and creating water-tight barriers to act as dams. Inside, waterproofing methods often include sump pumps, foundation coatings or sealants, and/or dehumidifiers.
How Much Should Basement Waterproofing Cost?
Basement waterproofing ranges widely in cost, so if you have a hefty project in mind, it’s a good idea to get more than one estimate before committing to any work. Full-scale basement waterproofing can be priced between $3 and $12 per square foot, based on our research, bringing the total cost up to many thousands of dollars. Smaller maintenance issues or preventative measures may be less expensive.
Is Waterproofing a Basement Worth the Cost?
Waterproofing your basement protects against mold, which can be harmful to your health, and rot, which can be detrimental to your home’s structural integrity. Choosing to waterproof your basement may be costly, but it protects you against higher costs (and potentially dangerous) problems later on. Basement waterproofing companies like Ameri-Dry offer warranties that last for the life of the structure, which can add value to your home when it’s time to sell. Overall, it is usually worth it to fix your basement moisture issues before they become a larger problem.
How Long Does Basement Waterproofing Last?
Most basement waterproofing systems last for a maximum of about 10 years. That said, if you shop around for a company with a lifetime warranty, you may be able to cash in on free or low-cost ongoing maintenance that will keep your basement dry without added costs.
How Do I Choose a Waterproofing Company for My Basement?
To choose a waterproofing company for your basement, start by reviewing providers in your area with good, consistent reviews, information about courteousness, honesty, and efficiency, which can be hard to gauge with just a quote. If you’re facing a significant expense, try to get quotes from more than one company: This will help you avoid paying for services you don’t need and confirm whether any large undertakings are necessary to solve your issue.
Once you’ve settled on a provider, ask questions about potential extra costs, warranty coverage, timeline, and any potential mess or wreckage that might render part of your home or yard temporarily unusable.
To choose the best basement waterproofing companies, we looked first for businesses with a footprint in at least half a dozen states that might be available to help a large number of readers, prioritizing companies like Basement Solutions, which boasts nearly 200 contracting partners.
