Best Overall: Basement Systems

Basement Systems

Basement Systems

Why We Chose It

Available nationwide via more than 180 local contractors, Basement Systems’ versatile waterproofing solutions have been trusted by homeowners and contractors for more than 30 years.

  • Widely available

  • Lifetime warranty on all products

  • 30+ patented waterproofing solutions

  • Service and policies vary across local providers

Founded in 1987 by Larry Janesky in Connecticut, Basement Systems now holds more than 30 patents and nearly 20 prizes for innovation in the waterproofing space. Its drainage pipes, dehumidifiers, sump pumps, and other solutions are used by nearly 200 local contractors around the country, making it one of the most widely available basement waterproofing companies out there.

Quotes vary widely based on your location, your home size, and the scale of the moisture problem in your basement. To get an accurate idea of how much a Basement Systems solution will cost, enter your ZIP code on the company website to find a local provider and schedule a free waterproofing consultation and estimate. The company also staffs a customer service telephone line to answer questions and schedule appointments.

Reviewers praise Basement Systems’ reliability, clean workmanship, and long-lasting effectiveness. Most seem to come away from their investment feeling that the basement waterproofing was money well spent. Basement Systems does protect its products with a “lifetime warranty,” but since its solutions are offered almost entirely by local contractors, the service and policies surrounding that promise may vary from place to place along with specific standards and requirements for technicians. Be prepared to discuss any urgent questions about the specifics with your local provider rather than with Basement Systems as a whole.

Best Warranty: BDry



Why We Chose It

BDry operates more than 50 locations across 24 states, boasting one of the best and most all-encompassing lifetime warranties in the industry.

  • Lifetime warranty

  • In operation since 1958

  • Costs vary widely

  • Installation time can run longer than competitors

BDry places plenty of stock in its impressive lifetime warranty: The company often points out that a home waterproofed 60 years ago could still be covered by its guarantee, a feat not many competitors can match. The company was founded in 1958 and is still going strong across more than 50 locations, with a reliable product and capable technicians that make BDry a top waterproofing choice, even beyond its formidable warranty.

To get an idea of how much BDry basement waterproofing will cost in your home, schedule a free inspection. A certified consultant will inspect your basement, take measurements, and offer an estimate depending on the size of the space and the severity of your water problem. If the job requires outside help—a plumber or an electrician, for example—BDry will refer you to an outside professional.

Should you decide to engage BDry for basement waterproofing, the installation process will likely involve temporarily removing a portion of your basement’s floor slab, creating a slope to promote drainage, drilling “weep holes” into any concrete blocks, and/or installing BDry’s “Rigid Sealer,” a waterproofing membrane, onto interior walls. BDry warns that it can take more man-hours than many competing waterproofing companies, but insists that it will be worth the extra time—something backed up by scores of positive customer reviews. You can contact BDry’s customer service by phone with any questions or schedule your consultation from 8 am. to 5 p.m., Monday through Friday.

Best Customer Service: Ameri-Dry



Why We Chose It

Ameri-Dry evaluates each home individually to recommend its best waterproofing solution, offering customers a range of options to consider before committing and a detailed work order prior to starting the job.

  • Detailed work order, walkthrough, and final inspection

  • Full “life of the structure” warranty

  • Cost hard to predict without inspection

  • Limited service area

Ameri-Dry reviewers praise the company’s efficient workmanship, courteous service, and long-lasting results—which are all important qualities in a company you trust to strengthen your home against damage. In business since the mid-1980s, the company has a presence in Maryland, Pennsylvania, Tennessee, Delaware, and Virginia. Customers in Ameri-Dry’s service area can call or book online for a free in-home inspection.

Once you engage Ameri-Dry, a technician will investigate the source of any leaks before recommending a treatment plan that takes your budget and the severity of your issues into account. Most commonly, AmeriDry will recommend installing an interior train tile system, but for extreme moisture problems, treatment can be as intensive as a total excavation—a costly, but occasionally necessary, last resort.

Before beginning work, you can count on Ameri-Dry to share a detailed work order, communicating how each point of the plan will take place and why it's necessary. Your foreman will be open and communicative throughout the process, and that over-the-top good service extends long after the team leaves your home: Ameri-Dry offers a full “life of the structure” warranty, which means it’s fully transferable (with no fees) when you sell your home—a major plus for property owners.

Most Transparent Pricing: Everdry



Why We Chose It

As one of the only basement waterproofing businesses to share an average price per square foot online, Everdry stands out for its price transparency in addition to an emphasis on interior and exterior work.

  • Many local branches share average per-square-foot pricing

  • Comprehensive approach

  • Details about warranty are unclear

  • Only 18 locations

Since its founding in 1983 in Cincinnati, Everdry has been an innovator in the waterproofing market, developing multiple patented systems and offering a wide range of services at a transparent and fair price.

Reviewers praise the company's comprehensive approach, adherence to projected timelines, and willingness to return quickly to resolve any lingering cosmetic or functional issues—even after the job is complete.

Everdry's waterproofing services generally run between $3 and $9 per square foot, and installations tend to take around two or three days. All Everdry locations extend at least a one-year warranty that is transferable if you sell your home and extendable yearly—and some locations offer free warranties with much longer durations. Customer service is reachable through a toll-free number, with waterproofing services available at 18 locations across eight states: Georgia, Illinois, Indiana, Michigan, New York, Ohio, Pennsylvania, and Wisconsin.

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 your bottom level, 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 much costlier (and potentially dangerous) problems later on. Basement waterproofing companies such as like AmeriDry 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, looking out for any 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 that have a footprint in at least half a dozen states that might be available to help the largest number of readers, prioritizing companies like Basement Solutions, which boasts nearly 200 local contracting partners. We looked at customer reviews, paying special attention to any mentions of technician behavior, timeliness, transparency, and reliability, and then considered what kind of guarantee customers could count on once the work was done. Nearly all of the top basement waterproofing companies offered some kind of warranty, with some guaranteeing their work for the lifetime of the structure in question.

We also considered customer service—including what kinds of checklists and services are in place to communicate with homeowners—and price transparency, seeking easy-to-find posts about price per square foot that could be accessed without an appointment or an in-person sales pitch.
