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.
Misclassifying a crack is the single most common mistake in this trade — treating a structural crack with the wrong material, or injecting a crack that actually needed a broader drainage fix behind it. We classify before we inject, every time.
Misclassifying a crack is the most common mistake in this trade, and it's the first thing we check on every Lexington Park, MD job.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Lexington Park, MD cracks that are currently letting water in.
A single crack repair is one of the most predictably priced jobs we do — no surprise scope creep.
Polyurethane expands to fill voids behind an actively weeping wall; epoxy is reserved for cracks that need structural bonding.
Every Lexington Park, MD 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.
We document crack width and location with photos before and after injection so you have a record of the repair.
Fast turnaround matters during a real estate transaction, and we prioritize scheduling for time-sensitive pre-sale repairs.
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.
"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."
— Lexington Park Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Lexington Park Homeowner
"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."
— Lexington Park Customer
"Fast, clean work — no mess left behind after the injection ports were patched."
— Lexington Park Homeowner
Active leaks get flexible polyurethane regardless of classification, since stopping water intrusion is the immediate priority.
We repair cracks of nearly any size — hairline cracks are often the easiest and cheapest to seal before they widen further.
Epoxy is better for structural bonding on a non-leaking crack; polyurethane is better for a crack that's actively weeping since it cures even with water present.
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.
Turnaround is usually fast enough to fit within a typical closing timeline.
