A fair quote starts with rigorous measurements. Performance BTP delivers reliable estimates, neither inflated nor under-priced, based on real Paris-region market rates — for professionals as for project owners.
Estimating without measurements is guessing. The measurement quantifies each item precisely: surfaces, lengths, volumes, material quantities. This is the basis that supports a defensible quote, whether for budgeting a project or for issuing a credible estimate to a client.
Performance BTP works from the real, current Paris-region price ranges. A floating estimate undermines credibility; a fair one secures margin and the client relationship. We clearly distinguish material cost, labour, and overheads.
For a contractor, accurate and fast quoting is a decisive commercial advantage: quicker estimates, controlled margins, fewer nasty surprises mid-job. It also separates serious firms from those that quote on the back of an envelope.
A precise measurement is the foundation of a reliable quote. Our method: laser surface survey (accuracy ±1%), deduction of openings according to trade rules, identification of applicable deductions per trade (in painting, openings ≥ 0.5 m² are deducted per NF P 74-201), and cross-verification (volume method vs surface method). Measurement errors are the primary cause of budget overruns and insufficient margins — a surface underestimated by 10% on one package can turn a profitable project into a loss-making one.
Our price database, updated quarterly for the IDF market, covers more than 200 work items. Key 2026 benchmarks: Painting: €18 to €45/m² painted depending on preparation quality and finish. Tiling: €55 to €180/m² fitted depending on format and material. Flooring: €65 to €220/m² fitted depending on species and grade. Electrics: €8,000 to €18,000 for a full rewire of a 60 m² flat. Bathroom plumbing: €6,000 to €22,000 for a complete renovation depending on specification. These benchmarks allow you to quickly validate whether a quote is consistent with the market — or whether something is off.
Before consulting contractors, it is useful to have an estimate of the overall budget — to know whether the project is financeable and to calibrate your spend. We produce preliminary cost estimates based on a site visit or plans, with an accuracy of ±20%. This estimate allows you to: decide whether the project is financially viable, prioritise packages according to available budget, and approach contractors with a clear idea of what you are prepared to spend — which improves the quality and comparability of quotes received.
A growing contractor was losing tenders for being too slow to quote, and shaving margins out of fear of over-quoting. Setting up a measurement method and a reference price grid let him respond faster, with secured margins — and win more profitable jobs.
For a professional, quoting is not just paperwork: it's a commercial tool. A clear, fast, fair estimate builds trust and wins jobs. Quoting blindly is gambling your margin on a coin flip.
Performance BTP provides contractors with practical tools and manuals to structure their quoting and accelerate their estimates — a direct lever for profitability and growth.
