Before we quote in Aberystwyth
Surveys in Aberystwyth also cover the surrounding SY23 district and towns such as Llandrindod Wells and Newtown. Aberystwyth sits around 51 miles from Llanelli. 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 solid-walled homes in Aberystwyth, we check wall thickness and age first to confirm there's no cavity to fill.

Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.

Solid wall insulation in Aberystwyth: questions
Does solid wall insulation cause condensation?
It can if detailed poorly, particularly internally. A condensation risk check for the proposed build-up and careful detailing at joists, reveals and corners avoid it.
Is solid wall insulation worth it?
For many solid-walled homes it's one of the biggest single improvements to comfort, because the walls are often the largest heat-loss area. Savings depend on the home and heating, so we don't promise a figure.
Can I do one wall at a time?
Yes. Many owners start with the coldest or most exposed elevation, often a gable end.
