About this company
Basement Waterproofing Solutions is a family-run waterproofing and mold remediation company based in Staten Island, with additional offices in Freehold and Cranbury, New Jersey. The Mendola family has been waterproofing basements since 1961 — three generations deep. The current operation launched in 2012 when Sal Mendola restarted the business with his sister Barbara and his son Sal Jr., after selling the original Mendola Waterproofing company in 2010.
Their core strength is basement waterproofing: French drains, sump pumps, exterior drainage, sill plate repair, and foundation crack sealing. Mold services — testing, inspection, and remediation — are a secondary line. The website mentions HEPA air filtration, antimicrobial treatments, dehumidification, and mold encapsulation as part of their remediation process. They also handle structural foundation repair and crawl space waterproofing. The team runs 15 employees.
The company holds a CMRS (Council-certified Microbial Remediation Supervisor) credential, displayed on the mold services page, and shows ACAC affiliation. They offer financing and a warranty program. Their no-pressure sales approach is emphasized on the website — they say you will have time to discuss proposals with your spouse before committing.

Review consensus
Sal gets mentioned by name in multiple reviews as honest, hands-on, and personally involved in planning each job. Steve handles assessments and is praised for thoroughness and clear communication. Julio and Martin are called out as courteous, clean field workers who explain the process. Reviewers consistently highlight punctuality, clean work sites, and fair pricing. Several repeat customers appear — Jon Salmon mentions decades of use, Dawn Marie returned for a second job, and Jim L. came back after a flooring contractor damaged their original French drain. Joseph Charneco credits the company with keeping his basement dry during a major Staten Island storm that flooded his neighbors.

Sal (owner — positive across multiple reviews), Steve (estimator/project coordinator — positive across multiple reviews), Barbara (office/operations — positive), Julio (field technician — positive), Martin (field technician — positive), Jeremy (field crew — positive), Ruben (field crew — positive), Jay (field technician — positive), Alex (field technician — positive).
Every review in the set is positive, which is unusual — but the total count is small at 26. Ask for references from recent mold-specific jobs, since most reviews focus on waterproofing and French drain installations. Request to speak with Sal directly during the estimate phase, as his personal involvement is the most consistently praised aspect of the business.
Keep in mind
- They do both mold testing and mold remediation. A company that tests for mold and then sells you the remediation has a financial incentive to find problems. Consider getting an independent mold test before committing to their remediation proposal.
- This is primarily a waterproofing company. Mold services are a secondary offering. If your mold issue is not related to basement water intrusion, a dedicated mold remediation firm may have deeper mold-specific experience.
- Their service area spans Staten Island plus a wide swath of New Jersey — from Burlington County to Morris County. Confirm they regularly serve your area and will not subcontract the work.
- With only 26 Google reviews accumulated since 2015, the review volume is low for a company that has been operating for over a decade. There is less public feedback to draw from compared to larger competitors.
