About Quinn Plastering

Over 40 Years of Quality, Trust & Craftsmanship

Quinn Plastering has been delivering high-standard plastering and waterproofing solutions throughout Pembrokeshire for over four decades. We specialise in breathable K Rend silicone render systems, fibrous internal plastering, and masonry waterproofing for both modern properties and heritage buildings.

Whether it’s a new build, a cottage restoration, or damp protection on a coastal property, our experience and technical knowledge set us apart. We use advanced render systems designed for longevity, energy efficiency, and zero maintenance — all backed by manufacturer guarantees.

Our internal plastering systems are ideal for damp-prone walls and older buildings, using breathable mortars that reduce condensation, resist cracking, and improve comfort. Unlike standard gypsum plasters, these systems are engineered to perform in moisture-sensitive environments.

We’re proud to be Sovereign Chemicals-approved contractors and have carried out specialist work for large contractors, private clients, and housing associations alike. Every job is completed by skilled tradesmen with a focus on clean workmanship and durable results.
