Chimney Waterproofing

Complete sealing for tiled & metal sheeted chimneys — stops leaks at the source.

— Service Overview

Chimney Waterproofing done properly — once.

Chimneys are the single most common leak point on Cape Town roofs. We strip back failed flashings, prime the substrate, apply Uniflash membrane around the base, then finish with a rubberized topcoat for a watertight, weather-resistant seal that lasts 10+ years.

Do you work in winter?

Yes — but we need a dry weather window of 24–48 hours for primer and membrane to bond. We schedule around the forecast.
