Caulking & Grout Repair
Caulking, Re-Caulking & Grout Refresh
Mildewed tub lines, cracked kitchen seams, peeling shower corners — removed and re-laid for a clean, watertight finish.
About this service
Caulking and grout repair across Nassau County, Suffolk County, and Queens. Old caulk pulls away, grout cracks, mildew darkens corners — and water finds the gaps. We strip old caulk and grout completely, prep the joint, and lay a clean bead of mildew-resistant silicone or fresh grout, depending on the joint.

Questions
Caulking & Grout Repair FAQs
How often should I re-caulk my shower?
Most silicone caulk lasts 3–5 years in a regularly used shower before discoloration or pulling sets in.
Can you remove black mildew from my grout?
We treat surface mildew and re-seal. Deep, stained grout usually needs to be ground out and replaced — quoted on-site.
Will my shower be usable that same day?
Silicone needs 24 hours to fully cure before water exposure. We mark the area and leave instructions.
