Cavity-wall insulation in Ede

In Ede prices start from € 820 per job for an average home. 1970s-80s family homes on the edge of the Veluwe: built just before the insulation requirement and thus rewarding retrofit candidates.

Your request goes straight to local professionals in and around Ede; they respond as soon as possible and you compare up to 3 quotes and decide.

For an average home you pay € 1,500 to € 3,000, including labour and materials. Floor insulation costs € 1,200 to € 2,800, crawl-space (ground) insulation € 800 to € 1,800 and an insulation survey with thermal scan € 95 to € 250. The facade surface drives most of the price: a terraced house has two facades to insulate, a detached home four.

That mainly depends on the construction year. Cavity walls came into use from roughly 1920; older homes often have solid walls without a cavity. Between about 1920 and 1975 the cavity was usually left uninsulated — the classic retrofit candidate. After 1975, insulation at build became increasingly common. The installer checks beforehand with a borescope inspection: if the cavity is wide enough, clean and dry, it can be filled.

The installer drills small holes in the mortar joints of the outer facade, injects the insulation material into the cavity and then neatly finishes the holes. Everything happens from the outside: nothing needs altering indoors and in most homes the work is completed in one day.

There is no single best material for every home: EPS beads, glass-wool flakes and PUR foam each have their own price, insulation value and application. Which one fits depends on the width and state of the cavity — the installer assesses that during the borescope inspection. Ask each quote for a short justification of the material choice, so you can compare them fairly.
