External wall insulation & K-Rend · Watford & Hertfordshire
External Wall Insulation & K-Rendplanned for the whole exterior.
T&T Contractors provides external wall insulation and K-Rend rendering services across Watford, Hertfordshire and the surrounding areas, with the existing walls, access, preparation and intended finish considered together.
Clear before work begins
Insulation and rendering are not the same thing.
External wall insulation adds an insulating layer to the outside of a wall. Render provides the visible outer finish. Some properties may need one approach, some the other, and some a more detailed conversation about the existing condition before any work is agreed.
Existing walls
The current wall condition, access and external details help determine what needs to be assessed.
Proposed finish
Colour, texture and visible junctions should be considered as part of the whole exterior.
Preparation
The appropriate system, materials and preparation are confirmed after the individual property is assessed.
