About this company
Basement Waterproofing Solutions is a family-run operation based in Freehold, New Jersey, with additional offices in Cranbury and Staten Island. Their primary identity is waterproofing and drainage, not mold, though they offer mold testing, inspections, and remediation as part of a broader moisture-control package. The Mendola family has been in the waterproofing trade since 1961, making this a third-generation business.
Their French drain work stands out most. The website goes into unusual technical depth on pipe orientation, iron ocher management, and trench depth, which suggests real field knowledge rather than franchise-level boilerplate. They also handle foundation crack repair, structural stabilization with steel I-beams, crawl space encapsulation, and sump pump installation and maintenance. Financing is available.
Sal Mendola Sr. started tagging along on jobs with his father in 1966 and joined full-time in 1979. After selling the original Mendola Waterproofing company in 2010, he relaunched in 2012 as Basement Waterproofing Solutions with his sister Barbara and his son Sal Jr. The company now has 15 employees.

Review consensus
Sal Sr. and Sal Jr. get the most mentions by name, with reviewers consistently noting that one or both show up for the initial inspection, explain the problem clearly, and check in during the work. Barbara handles scheduling and office communication and draws praise for responsiveness. On the crew side, Julio, Edgar, Chris, Jeremy, Nathan, Jerry, and TJ are all mentioned by name in positive reviews. Recurring themes include crews arriving on time, finishing ahead of schedule, keeping the work area clean, and delivering results at fair prices. Multiple reviewers report dry basements after heavy rain following French drain installations. Several are repeat customers returning for sump pump maintenance.
0 found across 71 total reviews at 4.9★. No recent complaints to evaluate. There are zero negative reviews (3 stars or below) in the last 18 months across 71 total reviews at 4.9 stars.
The unusually clean review record likely reflects the owner-operated structure. When the owner does the estimates, checks on work in progress, and follows up after completion, the kinds of communication breakdowns that generate most negative reviews tend not to happen. Worth noting that several reviewers mention being repeat customers, which is a strong signal for a waterproofing company since it means the original work held up.
Sal Sr. (owner, estimates and inspections — positive). Sal Jr. (owner's son, estimates and site visits — positive). Barbara/Barb (office, scheduling and payment — positive). Jeremy (initial consultations — positive). Edgar (crew leader — positive). Chris (contractor — positive). Nathan (sales rep — positive). Julio (crew — positive). Jerry (crew — positive). TJ (crew — positive).
With 71 reviews at 4.9 stars and no recent negatives, this is an unusually well-regarded operation. Ask for Sal or Sal Jr. to do your initial inspection. If you need mold work, get a separate test from an independent lab before accepting their remediation proposal.
Keep in mind
- They do both mold testing and mold remediation. That means the same company diagnosing your mold problem also profits from fixing it. Consider getting an independent mold test before committing to their remediation services.
- Their service area spans at least 10 New Jersey counties plus Staten Island. With 15 employees, response times may vary depending on how far you are from Freehold or their other offices.
- This is primarily a waterproofing and drainage company. Mold remediation is a secondary service line, so ask about the specific training and experience of the crew assigned to your mold job.
