High-Level Mastic Repairs for Commercial Buildings

Published 24 August 2026

Written by Next Level Sealants

Commercial façades, cladding and window perimeters need high-level mastic repairs that last.

Why commercial buildings need high-level mastic repairs

Office blocks, apartments, hospitals and retail buildings have large areas of external sealant. When it fails, water can track into the building, damage interiors and create costly maintenance issues. Catching it early avoids bigger problems later.

Access options for commercial work

Commercial buildings often have busy surroundings, restricted ground space or tenants using the building. Rope access can reduce disruption in the right circumstances. MEWPs and scaffolding are also used where appropriate. The choice is made after a site-specific risk assessment.

Materials and standards

Commercial mastic repairs use sealants chosen for the joint size, expected movement, exposure and substrate. We select the right product for the application and prepare the joint before application. Work is documented with risk assessments and method statements where required.
