We classify every crack before injecting it — structural cracks get epoxy, active leaks get flexible polyurethane, and both get a written scope before we start.
Not every Newtonville, NJ foundation crack needs the same material or approach. A vertical settlement crack behaves differently than a stair-step block crack, and we adjust injection technique and material to match what's actually happening in the wall.
Our technicians are trained to tell a cosmetic hairline crack apart from one that signals structural movement, before recommending a fix.
Most crack injection appointments can be scheduled within a day or two of your call.
Pricing is based on crack length and injection material, quoted in writing before we drill any injection ports.
Polyurethane expands to fill voids behind an actively weeping wall; epoxy is reserved for cracks that need structural bonding.
Every Newtonville, NJ Foundation Crack Repair job starts with an inspection, not a generic package — here's what that typically includes.
Epoxy-injected cracks regain much of their original structural strength, which matters for load-bearing foundation walls.
Polyurethane cures even in the presence of water, which makes it the right call for a crack that's actively letting water through.
Stair-step cracking in block foundation walls needs a different injection port pattern than a vertical crack in poured concrete, and we adjust technique accordingly.
Vertical cracks are usually settlement-related and often isolated; horizontal cracks can indicate hydrostatic pressure pushing on the wall and get flagged for further evaluation.
Selling a Newtonville, NJ home with a flagged foundation crack? We can inspect, repair, and provide documentation for the buyer's lender or inspector.
Photos texted ahead of time help us prep for the visit and sometimes speed up scheduling.
A technician measures crack width, checks for wall bowing, and determines whether it's structural, cosmetic, or actively leaking.
We explain why we're recommending one material over the other so the choice isn't a black box.
We check the injection ports after curing to confirm the material fully filled the crack before we consider the job done.
"We were selling the house and the inspector flagged a foundation crack. They came out within two days, injected epoxy, and gave us documentation for the buyer's lender."
— Newtonville Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Newtonville Homeowner
"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."
— Newtonville Customer
"Stair-step crack in our block wall had us worried about the whole foundation. Turned out to be isolated and fixable with injection."
— Newtonville Homeowner
Crack classification is separate from water contamination — we assess whether the crack is structural or cosmetic based on width, pattern, and any wall bowing.
Catching a crack early with injection usually costs less than waiting until it's actively leaking.
We make the call on-site after inspecting the crack, not before we've seen it.
Multiple cracks or hard-to-access areas can extend the timeline, which we'll flag in the written quote.
If new movement occurs elsewhere in the wall, that's a separate issue we'd assess independently.
Yes — we provide before-and-after photos and a repair summary that Newtonville, NJ buyers, sellers, and lenders commonly request.
