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.
