Before we quote in Haverfordwest
As well as Haverfordwest itself, we quote in Milford Haven, Carmarthen and Llanelli. It's roughly 36 miles from Haverfordwest to Llanelli, the largest town in Dyfed. West Wales has a high share of older solid-walled and stone homes, many in exposed coastal or rural settings.
Parts of Dyfed fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
Silicone suits most rendering jobs in Haverfordwest, either on its own or over insulation.

Wales: planning and regulations
For homes in Haverfordwest, the local planning authority decides any borderline cases; changing a brick house to render, or work on flats, usually needs an application in Wales.
In Wales, insulating or re-rendering more than half of a wall's area is treated as renovating a thermal element under Approved Document L (Wales), so building control is involved before work starts.
How is silicone render applied?
On masonry, the wall is prepared and any loose material removed. A base coat with glass-fibre mesh is applied over the whole wall to resist cracking, followed by a primer and the silicone finish, trowelled to its grain size. On EWI, the same base coat, primer and finish go over the insulation boards.

Silicone render in Haverfordwest: questions
Can I paint silicone render later?
Yes, with a compatible silicone paint, though through-coloured render rarely needs it.
Does silicone render crack?
The mesh-reinforced base coat and the render's flexibility make cracking much less likely than with sand and cement, but structural movement in the wall can still show through.
Can silicone render go over old render?
If the old render is sound and well bonded, often yes after cleaning and priming. Hollow or cracked areas are cut out and repaired first.
