Long-life coatings that protect and transform your home
Super-hydrophobic coatings, masonry paint and render protection systems that keep your walls dry, warmer and looking their best for years.
Weatherproofing and refresh for masonry, render and pebbledash
Modern wall coatings do more than paint — the best products are breathable and super-hydrophobic, letting the wall release moisture from inside while shedding rainwater on the outside. That means drier walls, better insulation performance and less risk of frost damage.
We work with tested coating systems suited to your wall type, whether that's smooth render, pebbledash, brick or stone. Every job starts with a survey of the existing walls, and any repairs are completed before coating so the finish lasts.
Choosing the right system matters — a cheap masonry paint over damp or crumbling render will fail within a couple of winters. We only specify systems with genuine, insurance-backed manufacturer warranties.

A complete exterior wall coatings service under one roof
Everything you need for this area of your property, delivered by qualified specialists — with one point of contact from assessment through to sign-off.
Super-Hydrophobic Coatings
Advanced breathable systems that repel water while allowing walls to release trapped moisture. 15–25 year warranties.
Premium Masonry Paint
Traditional high-build masonry paint in a wide colour range, applied over full preparation and primer.
Render Repair
Cracked, blown or crumbling render cut out and made good before any coating goes on — the difference between a finish that lasts and one that fails.
Pebbledash Sealing
Consolidating primer and coating systems specifically for tired pebbledash — no need to strip and re-render.
Colour & Finish Choice
Wide standard palette plus bespoke colour matching from an existing sample or paint reference.
Thermal Benefits
Dryer walls insulate better — a dry brick wall retains significantly more heat than the same wall soaked through.
Water beads and rolls off — that's what a proper coating looks like
The difference between a real weatherproofing coating and standard masonry paint is visible from day one. Rain beads on the surface and runs off rather than soaking in, keeping the wall behind dry through every British winter.
Because the coating is breathable, any moisture already inside the wall from the previous winter can escape as vapour — so you dry the wall out rather than sealing damp in.
- Repels rain and driving weather
- Breathable — no trapped moisture
- UV-stable — colour holds for years
- Self-cleaning — dirt washes off

The exterior is what protects everything inside
Wet walls waste heat
A damp brick wall can lose up to a third more heat than the same wall dry — a real hit to energy bills every winter.
Kerb appeal drives value
The outside of your home is the first thing buyers, neighbours and valuers see. A crisp, uniform finish transforms perception.
Prevents costly repairs
Coatings stop rain penetration, frost damage and render blow-out — all far cheaper to prevent than to repair later.
Frequently asked questions
How long do exterior wall coatings last?+
Quality breathable coating systems typically carry manufacturer warranties of 15–25 years when properly applied. We'll share exact figures for the system we recommend.
Will a coating trap moisture in my walls?+
The systems we use are breathable — they let water vapour escape from inside while blocking rain from outside. That's the difference between the right coating and cheap masonry paint.
Can you match my existing colour?+
Yes, coatings are available in a wide range of colours and can usually be matched to existing paintwork or a specific sample.
Do I need to move out during the work?+
No — coating work is entirely external and doesn't affect access to the property. We work around your daily routine.
Is scaffolding included in the price?+
Yes, any scaffolding or access equipment needed is included in your fixed written quote — no bill-shock extras.
Can you coat over existing paint?+
Often yes, provided the existing paint is sound. If it's flaking or unstable we'll remove it as part of the preparation — we'll assess this at the survey stage.
