Best for
- Homeowners in Gloucester County, Camden County, or the Cherry Hill-to-Vineland corridor who need mold remediation tied to a water intrusion problem.
- Buyers who want a single company to handle both the moisture source and the mold removal in a basement or crawl space.
- Owners of older or historic properties in South Jersey who need masonry restoration alongside waterproofing.
- Homeowners who have been frustrated by franchise operations and want to work directly with the business owner on every step.
About this company
South Jersey Waterproofing is a waterproofing and structural repair company based in Williamstown, NJ, that also offers mold remediation and testing. Their primary identity is basement and crawl space waterproofing, foundation repair, and historical masonry restoration. Mold work is a newer addition to their service line.
What stands out is the integration of waterproofing and mold work under one roof. Because mold problems in basements and crawl spaces almost always trace back to water intrusion, they can address the moisture source and the mold in a single engagement. Their mold remediation page describes a process that includes HEPA filtration, containment barriers, and antimicrobial treatment. They also offer dehumidification systems. The historical restoration work is genuinely unusual for a company in this space — they have done projects at Pine Valley Golf Course and the Gloucester Township Municipal Courtroom.
This is a third-generation family business. The Falzarano family runs estimates, supervises jobs, and works alongside their crews. They do not use subcontractors. Multiple reviewers specifically note that the owner or a family member was on-site during their project. They claim over a century of combined experience across the family.
With a 4.7-star rating on 36 Google reviews and only one negative review in the recent window, the track record is strong for a small operation. Nearly every review names Phil by name, which is uncommon — it signals a company where you are dealing directly with ownership from estimate through completion.

Review consensus
Phil is named in the vast majority of reviews and praised for honest assessments, clear communication, and not pushing unnecessary work. Multiple reviewers note he talked them out of more expensive options or advised them to contact a previous contractor first. Crews are consistently described as punctual, efficient, and meticulous with cleanup. Several reviewers mention the family-owned aspect as a positive — they dealt with the owner directly rather than a sales rep. Tim is mentioned for responsive Sunday service calls. Pricing is frequently described as fair or the most competitive among multiple bids.
1 found across 36 total reviews at 4.7★. One reviewer (Dave Carr) describes hiring Anthony for a floor-leveling job in late 2023, paying in full upfront, and returning from seasonal travel multiple times through April 2025 to find the work still not done to contract. The reviewer reports the floor still has a slope and hardwood floors cannot be installed. The owner did not respond to this review.
The single negative review describes a different type of work (floor leveling) than the waterproofing and drainage projects that dominate the positive reviews. It also involves a different staff member (Anthony rather than Phil). This may reflect uneven quality when the work falls outside the company's core waterproofing specialty. The owner's 0% response rate on negative reviews is worth noting — the company does not publicly engage with complaints.
Phil (owner/estimator — overwhelmingly positive across 20+ reviews for honesty, communication, and hands-on involvement). Phil F (same person referenced by full initial — positive, described as easy to understand and not pushy). Tim (service technician — positive, praised for responsive Sunday service call). Anthony (estimator/worker — negative, associated with the unfinished floor-leveling complaint).
If your project is waterproofing, drainage, or crawl space mold tied to water intrusion, Phil and his crew have a strong and consistent track record. Ask to work with Phil directly. For work outside their core waterproofing specialty, get completion milestones and payment terms in writing before committing.
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 test to confirm their findings before signing a remediation contract.
- Their core business is waterproofing, not mold. If your mold issue is not related to water intrusion — say, an HVAC or roof leak — they may not be the right fit.
- They claim service across a wide swath of New Jersey and into Pennsylvania (Philadelphia, King of Prussia, Yardley). For locations far from their Williamstown base, ask whether the same family crew will handle your job.
- The one recent negative review describes a floor-leveling job that went unfinished across multiple visits over two years, and the owner did not respond to it publicly. Ask about timelines and completion guarantees in writing before paying in full.
