Cavity insulation for new builds and extensions in Dalkeith

Looking for cavity insulation for new builds and extensions in Dalkeith? We survey first, name the installer, their scheme registrations and the guarantee on the quote, and only then book the work. For new walls the cavity is insulated as it is built, using full-fill mineral wool batts or partial-fill boards fixed to the inner leaf.

Cavity insulation for new builds and extensions for Dalkeith properties

We cover Dalkeith and the EH22 postcode district, including nearby Musselburgh, Livingston and Bathgate. It is about 18 miles east of Livingston.

Where a Dalkeith property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. If a wall in Dalkeith is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.

Wind-driven rain is the first thing the surveyor weighs up. Lothian has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

For regulations, in Dalkeith no building warrant is needed for insulation within a wall, but the work must meet the building standards.

What we work from

Your architect's or designer's specification and the energy calculation for the job. We match the product, thickness and fixing to that spec, keep cavities clean as the walls rise, and fit cavity trays, closers and stop ends where shown so the building control inspection goes smoothly.
