Customer feedback for Basement Systems varies by dealer location, but the brand maintains a strong reputation overall. Reviews for the company’s individual contractors praise the professionalism of contractors, the effectiveness of the systems, and the cleanliness of installation crews. Negative reviews cite scheduling issues and high prices. While many concerns seem to arise from installation issues, reviewers note that contacting the company directly was key in solving their problems.
“I had a significant issue with an independent installer of their product (a full crawl space encapsulation, including vapor barrier, insulation, drainage, and sump). Basement Systems reached out to that independent installer and achieved resolution within less than an hour. I had been trying for nearly 8 weeks, 4 with no response. I respect a business which stands behind its product and can exert pressure on it’s affiliates to perform. If you have an issue with an installer of a Basement Systems product, it is worth your while to reach out directly to Basement Systems to determine whether they can help.” — Google Review
“Basement systems did the water guard, vapor barrier, a super sump with battery back up and installed 3 windows and sun wells. Very happy with the job and the customer service. Had torrential rain twice since then and basement is completely dry.” — Trust Pilot Review
“The best part is that Basement Systems covers the warranty of the systems even if the waterproofing company that did your job goes out of business- they’ll just send over another company under their name to keep maintaining your systems and such. All of the companies under Basement Systems get trained very well and get trained the same way so I would trust them over all other waterproofing companies.” — Reddit Review

Before investing in basement waterproofing, crawl space encapsulation, or foundation repair, homeowners often have questions about cost, timelines, warranties, and what to expect from the process. Basement Systems operates through a network of independent local dealers across North America, which means pricing, services, and policies can vary by location — but the company’s nationwide standards and product quality remain consistent.
Below are some of the most common questions people ask before hiring Basement Systems, along with detailed answers and quick tips to help you make an informed decision.
Most basement waterproofing or crawl space encapsulation projects are completed in one to three days, depending on the size and complexity of the job. Foundation repairs can take up to a week or longer if the damage is severe, excavation is required, or specialized materials are needed. Your local dealer will provide a more accurate timeline after the on-site inspection.
Quick Tip: Schedule your project during a stretch of dry weather if possible — it can speed up the work and reduce delays.
Basement Systems offers transferable lifetime warranties on many of its systems, including the WaterGuard® interior drainage system and the CleanSpace® crawl space encapsulation system. This means the warranty stays with the home even if it is sold. Some services or products may have different coverage terms, so it’s best to review your dealer’s specific warranty documents before work begins.
While most quotes from Basement Systems dealers are comprehensive and itemized, additional costs can arise if unexpected issues are uncovered during installation — such as the need for excavation, mold remediation, or structural reinforcement. Asking for a full written estimate and discussing potential contingencies with your dealer can help you avoid surprises.
Quick Tip: Ask your dealer to outline “possible add-on costs” during the estimate so you can budget for worst-case scenarios.
Yes. Many Basement Systems dealers partner with third-party financing companies such as Morehouse Finance to offer payment plans, including low-interest and no-interest promotions for qualified customers. Terms and availability vary by dealer, and all financing is subject to credit approval.
Basement Systems is unique in its national network of certified local dealers who receive ongoing training in specialized systems. While some competitors focus solely on one aspect — like foundation repair or drainage — Basement Systems offers a comprehensive suite of services, including waterproofing, foundation repair, mold treatment, and crawl space solutions.
Quick Tip: If you’re getting multiple quotes, compare the scope of services — not just the price — to see which provider offers the most value.
In most cases, yes — particularly if your basement or crawl space has stored items in the work area. Your dealer may request that you clear the space ahead of time to allow safe and efficient access for the installation team. Some dealers can assist with moving items for an additional fee.
You can request a free, written estimate by calling your local dealer or filling out the online form on the Basement Systems website. A trained specialist will visit your home, inspect the problem area, and provide a detailed proposal outlining recommended solutions and associated costs.
Yes. Basement Systems specializes in crawl space encapsulation using products like CleanSpace® vapor barriers, drainage matting, and sump pump systems designed to keep moisture out. Encapsulation not only eliminates standing water but also helps control humidity, prevent mold growth, and improve indoor air quality.
Quick Tip: Ask about adding a dehumidifier to your encapsulation system — it can help maintain long-term moisture control.
Absolutely. Many older homes have unique waterproofing and foundation challenges due to aging materials, outdated drainage systems, and structural wear. Basement Systems’ dealers are trained to address these issues with customized solutions, whether that means installing modern waterproofing systems, reinforcing foundations, or improving ventilation and insulation in crawl spaces.
Quick Tip: If your home is more than 50 years old, ask for a full foundation inspection as part of your estimate to catch hidden issues early.
Basement Systems is a trusted, high-quality provider for homeowners who need reliable waterproofing and foundation repair services. With decades of experience, exclusive technology, and a network of vetted dealers, the company delivers lasting solutions — albeit at a premium price.
The company is best for homeowners who want long-term protection, are dealing with major moisture or structural issues, and are willing to invest in premium systems. It’s not necessarily ideal for small repairs or low-budget projects.
