01 — Method
How we calculate
Our prices are supplied and fitted: materials, labour, protection, waste disposal. The estimator applies our average 2026 prices in the metropolitan area, the finish level, your options and an access factor, then the VAT rate that applies to your home.
What makes the price vary
- The condition of the substrate: a floor to reinforce, a wall to straighten.
- Access: an upper floor with no lift, narrow lofts, an inner courtyard.
- Ceiling height: above 2.50 m, more material and scaffolding.
- Surprises revealed when work opens up: services to move, old insulation to remove.
That is why we give a range: the visit replaces it with a fixed price.

04 — Frequently asked questions
The quote, in full transparency
10-year builder’s warranty: policy no. DEMO-DEC-2026-04418 (fictional), Fictional Western Builders’ Mutual, mainland France.
Consumer mediator: free recourse in case of dispute, see the legal notice.
Cooling-off period: 14 days for a quote signed at home.
The estimator keeps only the characteristics of your project (never your contact details) for 30 days on this device.
Does the online estimate commit me?
No. It is an order of magnitude to prepare your budget; only the detailed quote, prepared free of charge after the visit, commits us.
Why a range rather than a price?
The condition of the substrate, access, ceiling height or a service to move can only be seen on a visit. The range covers common cases; the detailed quote replaces it with a fixed price.
Which VAT rate?
5.5% for insulation of a home more than 2 years old (with minimum performance), 10% for improvement and fitting-out work on a home more than 2 years old, 20% for a home less than 2 years old. Since March 2025, a simple mention on the quote replaces the certificate.
Can I cancel after signing the quote at home?
Yes: a quote signed at your home after the visit is an off-premises contract, with 14 days to withdraw. If you want us to start before the end of that period, you must ask for it expressly.
How does payment work?
30% deposit on order, 40% at the start of the works (or at the end of manufacture for joinery), the balance at handover. Bank transfer or cheque: no cash payment above €1,000.
Is waste disposal included?
Yes, and every quote itemises it: estimated quantities, sorting, professional recycling centre and cost, as regulations have required since 1 July 2021.
