Expansion & Control Joint Sealants

Mersco Miami installs and replaces high-performance expansion joint sealants for commercial buildings, condos, HOAs, and multi-family properties across Miami-Dade and Broward County. We use flexible, UV-resistant sealants that handle Florida's extreme temperature swings without cracking or pulling away from surfaces.

Our crews work on parking garages, plaza decks, building facades, window perimeters, and concrete surfaces that require proper joint treatment. Whether you need new sealant installation during construction or replacement of failed joints on an aging building, we get it done right. Property managers, engineers, and building owners throughout Doral, Kendall, Hollywood, and Pembroke Pines trust Mersco Miami for joint maintenance that lasts.
