Whether it's a hairline settlement crack or a wider stair-step pattern showing wall movement, the right repair depends entirely on getting the diagnosis right before anyone reaches for resin.

Four commitments that separate a properly trained foundation crack repair crew from a generalist showing up with a truck and a hope.
Classification includes checking for horizontal displacement, stair-stepping in block walls, and correlating with any door or window frame misalignment.
A crack actively letting water through moves to priority scheduling — most Lyndhurst, VA service areas see a technician within hours for active intrusion.
Structural cracks requiring engineering evaluation are priced separately and clearly, never bundled silently into a standard injection quote.
Carrying both means the crew matches the material to the actual crack condition rather than using whatever's on the truck that day.
Each service below is scoped specifically to foundation crack repair, not a generic waterproofing menu with the name swapped in.
For cracks actively passing water, polyurethane injection resin is pumped in under pressure, where it expands to fill the full depth and width of the crack, including hairline branches a surface patch would miss.
This method is reserved for cracks confirmed as non-active — injecting epoxy into a still-moving crack just cracks the epoxy itself.
Stair-step cracking in block or brick foundation walls typically signals soil pressure or settlement issues beyond what injection alone resolves.
This is a specialized repair beyond simple crack injection, and we walk you through the engineering rationale before recommending it.
We evaluate downspout extensions, soil slope, and window well drainage as part of a complete crack repair, not an afterthought.
Four steps, start to finish — from the first call to a properly classified and injected crack.
Active water intrusion is flagged for priority same-day or next-day scheduling.
Most Lyndhurst, VA crack evaluations are scheduled within a few days for non-emergency cases, faster for active leaks.
You'll see the classification explained in plain terms — why this crack is a polyurethane candidate versus needing a structural referral.
Repairs carry a written warranty against re-leaking at the treated location.
