What we look for in Rhyl
We also cover Colwyn Bay and Llandudno, close to Rhyl. It's roughly 28 miles from Rhyl 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 homes in Rhyl, the survey starts with the wall itself: solid brick, stone or concrete, and whether any old render is sound enough to insulate over.

Planning and building control in Wales
We check Rhyl addresses for conservation areas and listing before quoting, because Welsh permitted development rules don't cover every external change.
Welsh Building Regulations expect walls to be upgraded when a substantial area is renewed, and building control signs the work off.
What does the survey check before EWI is specified?
- Wall construction and condition, including any damp, cracking or loose render
- Ground levels and the damp-proof course, so the system starts above splash height
- Eaves depth, verges and whether the roofline needs extending
- Window positions, cill depths and reveal space
- Services on the wall: gas, electric meters, flues, soil pipes, satellite dishes and lights
- Planning and Building Regulations position for your property and nation

External wall insulation in Rhyl: questions
Does external wall insulation cause damp?
Not when it is specified and detailed properly. Problems usually come from poor detailing: no starter track above the damp-proof course, gaps at cills and penetrations, or a vapour-closed system on a wall that needs to breathe. The survey checks moisture, ground levels and the wall type before a system is chosen.
Can EWI go over pebble dash?
Usually yes. The dash is tested for adhesion and hollow areas; sound dash can be insulated over with additional mechanical fixings, while loose areas are removed first.
How much does external wall insulation cost?
Our guide price for EWI is £105–£170 per m² of wall depending on the system, plus scaffolding. A typical three-bed semi with EPS and silicone render comes to roughly £10,200–£17,700 for the whole house, including scaffold. Installing insulation in a home is zero-rated for VAT until 31 March 2027, so that's the total. You get a fixed written price after a free survey.
