How much does concrete floor crack injection cost in New York?
Honest answer: it depends on the scope. Most concrete floor crack injection jobs start at free estimate, but the final price comes down to the size of the job, the materials you choose, access and site conditions, and whether any permits are involved. In New York, older buildings and tighter access can add labor, which is exactly why we quote a firm, flat rate after we see the job — never a vague hourly guess over the phone.

Common Questions
Frequently Asked Questions
Can any concrete slab be polished to a mirror finish?
No — soft or patched slabs may not take high grit. We test hardness and set a realistic sheen target.
Epoxy peeling — what usually caused it?
Poor prep, moisture, or oil. We won’t coat over failed contamination without mitigation.
How long before cars can drive on epoxy?
Product-dependent; often 48–72 hours for light traffic — stated on the system data sheet we follow.
Is grinding noisy/dusty?
Yes without controls. We use vacuums and containment; still plan neighbor notices in multi-family.
Polish vs epoxy for a loft living space?
Polish keeps concrete character and breathability; epoxy/overlays hide defects and add color. Choice follows slab condition and design.
Do you fix cracks first?
Structural vs cosmetic cracks are assessed differently. Cosmetic chase-and-fill is common before polish/coat.
