About us
Quietly fixing the draughtiest homes.
Cavity Wall Insulation is a team of surveyors and fitters who only do one thing: install insulation properly. No upsells, no clip-board high-pressure sales — just considered recommendations and tidy workmanship.
What we believe
British housing stock is some of the oldest in Europe. Most homes were never designed for the energy prices, weather extremes or carbon expectations of today. We exist to bring those homes up to a standard their owners can be proud of — warm in winter, cool in summer, and cheaper to run year-round.
How we work
- • Every job starts with a free local survey. No quote is ever issued without a real human visit.
- • We specify materials that match the building — breathable boards on solid walls, mineral wool in lofts, bonded bead in cavities.
- • Our installers are directly employed or long-standing partners. No anonymous sub-contractors.
- • Every job comes with a written guarantee and clear sign-off documentation.
