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 Gaithersburg, MD 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.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Gaithersburg, MD cracks that are currently letting water in.
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 Gaithersburg, MD Foundation Crack Repair job starts with an inspection, not a generic package — here's what that typically includes.
Structural cracks that aren't actively leaking get epoxy injection, which bonds the concrete back together rather than just sealing the surface.
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.
We document crack width and location with photos before and after injection so you have a record of the repair.
Selling a Gaithersburg, MD 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.
We also check the exterior grading near the crack, since poor drainage is often what caused it in the first place.
We explain why we're recommending one material over the other so the choice isn't a black box.
Most single-crack injections are completed in a few hours, start to finish, in one visit.

Crack classification is separate from water contamination — we assess whether the crack is structural or cosmetic based on width, pattern, and any wall bowing.
We repair cracks of nearly any size — hairline cracks are often the easiest and cheapest to seal before they widen further.
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 Gaithersburg, MD buyers, sellers, and lenders commonly request.
