About RenoQuant
RenoQuant gives European homeowners free, accurate tools to estimate renovation costs — before they talk to a single contractor. We believe that knowing what a project should cost is the first step toward getting fair quotes and avoiding overpaying.
Our calculators cover 18 project types from painting a bedroom to installing solar panels. Every estimate is grounded in real market data: Eurostat construction cost indices, manufacturer pricing, and — increasingly — crowdsourced cost reports from homeowners who've completed their projects.
How We Research Costs
Official Statistics
Eurostat construction cost indices (CC-BY-4.0) provide country-level baselines. We index 18 EU/EEA countries quarterly.
Market Prices
Material costs are sourced from manufacturer catalogues and major retailers, updated at least twice a year per region.
Homeowner Reports
We're building a crowdsourced cost database. When at least 5 anonymized reports exist for a region, we show real-world price ranges alongside our baseline estimates.
