External Wall Insulation Dartford

Warmer walls, lower bills

External wall insulation (EWI) fixes an insulating layer to the outside of the property, then finishes it with a protective render or cladding system. Because the insulation sits outside the wall rather than inside, it doesn't eat into room space, and it helps keep the existing structure warmer and drier.

What it actually helps with

• Reduces heat loss through solid or poorly insulated walls
• Helps eliminate cold bridging, a common cause of damp and mould
• Can meaningfully lower heating bills over time
• Refreshes the exterior appearance at the same time

Particularly worth considering for

Older properties with solid walls and no cavity tend to see the biggest benefit from EWI, since they typically lose the most heat through the walls. We'll assess your property's construction during the free survey and give you an honest view on whether it's a good fit.
