Crawl-space (ground) insulation

With ground insulation an insulating layer is applied to the floor of the crawl space, usually insulation chips or beads levelled into a covering layer. The layer insulates and at the same time slows the damp rising from the ground — which is why ground insulation is often chosen precisely for damp crawl spaces.

For an average home you pay € 800 to € 1,800, including labour and materials. Because the material is blown or poured in, ground insulation also works in low crawl spaces where floor insulation will not fit. Mention in your request whether water ever stands in the crawl space: with structural water the company first advises on the cause.

Ground and floor insulation are regularly combined with cavity-wall insulation in a single job — the company is there with its equipment anyway, which lowers the price per measure.
