Strong local matches
Best for: Northern NJ homeowners dealing with water damage or mold who want a locally owned restoration company with in-house testing, a 29-minute average response time, and 311 reviews at 4.9 stars.
Service area: PDQ is headquartered in Boonton, NJ and serves Northern New Jersey. Their website lists specific service pages for Bridgewater, Montclair, Livingston, Randolph, Allamuchy, Allendale, Alpine, Andover, and dozens of other towns across Morris, Bergen, Essex, Passaic, and surrounding counties. The claimed coverage area is broad for a single-location company.
Review snapshot: Leo Trinidad, Mike Moughrabie, and David Rebolledo draw consistent praise for fast response and clear communication across 311 reviews at 4.9 stars. But one recent reviewer cited poor work quality with no specifics, making it hard to evaluate (1 one-star review found).
Best for: Toms River-area homeowners dealing with basement water problems who also need mold remediation and want an owner-operated company with financing options and a transferable warranty.
Service area: Guru Waterproofing is based in Toms River, New Jersey (Ocean County), with a Manahawkin address also referenced on their BBB profile. They claim to serve all of New Jersey across northern (Bergen, Union, Essex, Hudson, Morris, Passaic, Sussex, Warren counties), central (Hunterdon, Somerset, Mercer, Union, Ocean, Monmouth, Middlesex counties), and southern regions (Atlantic, Burlington, Camden, Cape May, Cumberland, Gloucester, Salem counties). That is 22 counties covering the entire state, which is a very broad claim for an owner-operated company.
Review snapshot: Mike G gets consistent praise across dozens of reviews for hands-on involvement and competitive pricing, with Vincent and Kevin also noted. But 3 of 72 reviews are 1-star, citing license concerns, warranty non-responsiveness, and sloppy work.
Best for: Morris County and Essex County homeowners who want an owner-operated restoration company that handles water damage and mold removal under one roof, with flexible payment options.

The Phillipsburg reviewer is notable since that town is over an hour west of Dover.
Review snapshot: Tal draws consistent praise for honest assessments and telling people when no work is needed. But with zero 1-star reviews across 46 total, the review profile is unusually clean and hard to stress-test.
