Homes and walls in Milford Haven
We cover Milford Haven and nearby Haverfordwest, Carmarthen and Llanelli. It's roughly 38 miles from Milford Haven 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.
For older stone and early brick properties in Milford Haven, we look at a wood fibre and lime build-up first.

Approvals in Wales
Householder rules in Wales are similar to England's: in Milford Haven, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.
What finish goes over wood fibre?
A lime-based or mineral render designed for the system, applied over a reinforcing base coat. Lime finishes give the softer, slightly irregular texture that suits cottages and older terraces.

Wood fibre EWI in Milford Haven: questions
Can wood fibre go on a stone wall?
Yes, after levelling. Rubble stone is often uneven, so a levelling coat or adapted fixing method is used first.
Is wood fibre worth the extra cost?
On older solid walls the main benefit is moisture safety rather than raw U-value. If the wall needs to breathe, the cheaper option can cost more later.
Is wood fibre insulation fireproof?
No — it's a timber product. It chars rather than flaming readily, but it is combustible, so it's used on low-rise buildings within a tested system and never where non-combustible materials are required.
Do you cover Milford Haven?
Yes — we survey and quote wood fibre external wall insulation in Milford Haven (SA73) and nearby Haverfordwest, Carmarthen and Llanelli, with a fixed written price before any work starts.
