Mastic & Silicone Sealant Specialist in Portsmouth

Being based here means we can usually get to a Portsmouth job quickly, and small domestic resealing work often gets fitted in within the same week.

A lot of local housing stock is Victorian and Edwardian terracing with later bathrooms and kitchens fitted into it, so joints are rarely square. Beads are sized to the gap rather than forced into a standard width.

Coastal exposure matters here. External joints on Portsea Island take salt air and wind-driven rain, so external work uses low-modulus weather-resistant sealant and correctly backed joints.
