Frequently asked questions

The cost depends on the insulation method, the surface area and the condition of the property. For an old house without a cavity wall, this often means exterior wall insulation, interior wall insulation or roof insulation. A smaller insulation job often costs around €400 to €1,000, while multiple walls or a larger project usually ranges from €1,500 to €5,000 or more. Façade finishing, repair work or custom details can increase the price.

A smaller insulation job can often be completed within one working day. For multiple walls, roof insulation or exterior façade finishing, you should usually allow 2 to 5 working days.

The professional checks where most heat is being lost and determines which insulation method suits the property. The wall, roof or interior surface is then prepared and insulated, with attention to moisture, ventilation and a neat finish.

Zoofy works with checked professionals who are reviewed by previous customers. This helps you get support from someone experienced in insulating older homes.
