It takes approximately 3 to 4 weeks to fully complete all work on a 3-bedroom semi-detached house. Typically, larger homes will take longer, but this will for part of our initial free and no obligation survey.
The length of time taken to install EFI will depend on the size of your home but, as a guide, a typical 3-bedroom semi-detached house will take approximately 3-4 weeks from assembly to the dismantling of the scaffolding.
The purpose of External Wall Insulation is to insulate solid wall properties which can be made up of brick or concrete.
Most solid wall houses were built prior to the 1920s and are comprised of the Edwardian, Victorian or Georgian times. If you’re not entirely sure, you can find out by ideally checking your deeds, or manually drilling a test hole in the wall. Another way to test whether you’re eligible for External Wall Insulation would be to measure the wall thickness at an opening. Solid walls measure in the region of 225mm thick.
Most terraced houses in the UK are made up of a solid wall construction. If you currently live in a mid-terraced property, you can still use External Wall Insulation, even if your neighbours on either side choose not to by providing a ‘stop end’ at the edge of your boundary.
