External Wall Insulation in Gwynedd

S&K Property Investments & Improvement carries out external wall insulation throughout Gwynedd — one accountable team from first survey to final finish.

You get a straight assessment, a fair fixed price, and work carried out when we say it will be. Solid-wall and hard-to-heat homes lose a lot of warmth through the walls. External wall insulation (EWI) wraps the outside of the building in insulation and a fresh render or cladding finish — cutting bills, warming rooms and transforming the look in one job.

Our external wall insulation service in Gwynedd includes

• Insulation boards fixed to external walls
• Mesh, basecoat and weatherproof finish
• Silicone render or cladding top-coat
• Detailing around windows, doors and eaves
• Warmer rooms and lower heating bills
• Refreshed exterior appearance

We fix insulation boards to the wall, reinforce with mesh and basecoat, and finish in a durable render or cladding. It is ideal for solid-wall properties that cannot take cavity insulation, and it keeps the disruption outside.
