Cardiff render repair — honest advice, lasting finishes.
If your render in Cardiff has started cracking, blowing or staining, you're not alone. It's one of the most common exterior problems we see across Wales, and almost always fixable without ripping the lot off.
Algae and green staining on render in Cardiff is mostly cosmetic, but it's a sign the surface has gone porous. Left untreated, that porosity turns into freeze-thaw damage and the kind of chunky failures that need full re-rendering.
Once we've surveyed your property in Cardiff, you get a written, fixed-price quote — broken down by elevation so you can see exactly what each part of the job costs. No surprises, no day-rate creep.

Render repair questions from Cardiff homeowners
+Do I need to re-render the whole house, or just patch it?
Almost never the whole house. Most Cardiff jobs are localised — a blown patch under a sill, cracking around a bay, an elevation that's taken the brunt of the weather. We'll only recommend full re-rendering if the existing system has genuinely failed across the board.
+Will the work be disruptive?
Render repair is external work — we don't need access inside your home unless we're chasing the cause of internal damp. Scaffold and access goes up at the start, comes down at the end, and our crews working in Cardiff keep the site tidy throughout.
+How much does render repair cost in Cardiff?
Cost depends on the failure type and how much render is affected. A small blown patch on a Cardiff semi might be a few hundred pounds; a full elevation re-render with a silicone topcoat is significantly more. We give you a fixed written price after surveying — no estimates over the phone.
+Will damp inside go away once the render is fixed?
If the damp is being driven by failed render outside — and in Cardiff that's the most common cause we see — then yes, once the wall can dry out properly the staining stops spreading and inside surfaces can be redecorated. We'll always identify the cause before quoting.
+Do you offer a guarantee?
Every render repair we carry out in Cardiff comes with a 10-year workmanship guarantee in writing. Materials carry their manufacturer warranty on top of that — typically 15 to 25 years on modern silicone systems.
