Render Repair in Gwynedd
Cutting out blown, hollow and failed render and making good to match the existing finish.
Getting render repair right in Gwynedd depends far more on the substrate and the exposure than on the product name.
The prevailing picture in Gwynedd is slate and stone cottages, quarry housing and exposed coastal properties. That means extreme driving rain on slate and stone construction comes up more here than almost anywhere else. The area sees among the highest rainfall in the UK with severe exposure, which is the single biggest factor in how long any render lasts here.
Local factor. Snowdonia records some of the highest rainfall in britain, and any non-breathable render on stone here will trap water within a single winter.
Is render repair right for a Gwynedd property?
Choose repair over a full re-render when failure is localised, the bulk of the elevation is sound, and the cause can be fixed.
That decision gets made at the survey, not on the phone. We will tell you plainly if a different system would serve the building better — including when a cheaper one would.

FAQs
Render Repair in Gwynedd — questions
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
Can you render over existing render?
Sometimes, if the existing coat is completely sound and well-bonded. We hammer-test it first. Anything hollow has to come off, because covering failure just hides it.
Are you insured?
Yes — full public liability cover, and we can send the certificate before we start. We are happy to provide RAMS for commercial and contractor work.
What areas do you cover?
We work UK-wide, with teams across England, Scotland, Wales and Northern Ireland. If we are not the right firm for your location we will tell you rather than waste your time.
How do I know if my render has blown?
Tap it with your knuckle or a small hammer. Solid render sounds dull and dense; blown render sounds hollow and drummy. Bulging and hairline map-cracking are other signs.
Will the repair match my existing render?
We colour and texture match as closely as possible, but weathered render never matches fresh render exactly. On a visible front elevation, rendering the full wall gives a cleaner result.
