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 Marriottsville, 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.
Misclassifying a crack is the most common mistake in this trade, and it's the first thing we check on every Marriottsville, MD job.
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.
We scope every Foundation Crack Repair job in person before quoting it, since two properties with the same symptom rarely need the same fix.
Epoxy-injected cracks regain much of their original structural strength, which matters for load-bearing foundation walls.
Cracks that are still weeping get flexible polyurethane, which expands into voids and stays flexible enough to handle minor seasonal movement.
We also check for bowing alongside stair-step cracks, since that combination can point to a bigger structural issue.
We document crack width and location with photos before and after injection so you have a record of the repair.
Selling a Marriottsville, 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.
A technician measures crack width, checks for wall bowing, and determines whether it's structural, cosmetic, or actively leaking.
You'll get a price based on crack length and material — epoxy or polyurethane — before any drilling starts.
Most single-crack injections are completed in a few hours, start to finish, in one visit.
"Crack in our basement wall had been leaking for a year before we finally called. Injection took less than an afternoon and it's been dry since."
— Marriottsville Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Marriottsville Homeowner
"Appreciated the before-and-after photos for our records in case we ever need them for a future sale."
— Marriottsville Customer
"Stair-step crack in our block wall had us worried about the whole foundation. Turned out to be isolated and fixable with injection."
— Marriottsville 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.
Turnaround is usually fast enough to fit within a typical closing timeline.
