Homes in Delft
Delft has around 106,000 inhabitants. Characteristic: steep roofs in the listed centre, flat roofs on the post-war walk-ups and well-insulated new builds in the university quarter: attic and roof work differs sharply by neighbourhood. This partly determines the price and approach of the job.

Frequently asked in Delft
What does attic-floor insulation cost in Delft?
In Delft prices start from € 1070 per job for an average home. Steep roofs in the listed centre, flat roofs on the post-war walk-ups and well-insulated new builds in the university quarter: attic and roof work differs sharply by neighbourhood.
How fast do professionals respond in Delft?
Your request goes straight to local professionals in and around Delft; they respond as soon as possible and you compare up to 3 quotes and decide.
What does roof insulation cost?
That depends heavily on the measure. Insulating the attic floor costs on average € 1,000 to € 2,500 for an average home and is the fastest, cheapest option for an unused attic. Insulating the sloped roof from the inside costs € 2,500 to € 8,000 per job (roughly € 50 to € 100 per m²), including the finish. Insulating a flat roof from the inside comes to € 1,500 to € 5,000 per job (roughly € 40 to € 90 per m²). An insulation survey with thermal scan costs € 95 to € 250.
Attic floor or roof slope — what is best to insulate?
That depends on what you do with the attic. If you use it only for storage, insulating the attic floor is almost always the smartest choice: cheap, fast and without a finish, because the heat need go no further than the lived-in floor below. If you want to use the attic as a room, you insulate the roof slope itself, so it stays comfortable up there too. If you are unsure, an insulation survey with thermal scan reveals it.
Do you also do roof replacement or exterior insulation?
No. This site focuses on insulating from the INSIDE: the attic floor, the roof slope from the inside and a flat roof via the underroof, with the roof covering intact. Exterior insulation — tiles off, insulation underneath and a new roof covering — is a roofer's job; for that you work with a specialised roofing company.
Do you also do cavity-wall or floor insulation?
No. This site is about the roof and attic. Cavity-wall insulation (the facade), floor insulation and crawl-space (ground) insulation belong to specialised companies for the shell beneath and around the home — a different trade from roof insulation.
