Homes and walls in Llandudno
As well as Llandudno itself, we quote in Colwyn Bay, Rhyl and Bangor (Gwynedd). It's roughly 40 miles from Llandudno to Wrexham, the largest town in Clwyd. North Wales has many solid stone and slate-built homes, Victorian seaside terraces and post-war council estates.
Exposure to wind-driven rain varies across Clwyd: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
For solid-walled homes in Llandudno, we check wall thickness and age first to confirm there's no cavity to fill.

Wales: planning and regulations
We check Llandudno addresses for conservation areas and listing before quoting, because Welsh permitted development rules don't cover every external change.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.
How can I tell if my walls are solid?
Measure the wall thickness at a window or door: about 225mm (9 inches) of brick usually means solid, while 260mm or more often means a cavity. On exposed brick, a pattern with bricks laid end-on (headers) every few courses points to solid construction. Stone walls are usually solid regardless of thickness. Age is a strong clue too — most homes built before the 1920s are solid-walled.

Solid wall insulation in Llandudno: questions
Can I do one wall at a time?
Yes. Many owners start with the coldest or most exposed elevation, often a gable end.
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.
