How our numbers work

  1. 1. Sourced prices. Unit prices come from published 2025–2026 cost guides and city-level data, cross-checked against at least two independent sources whenever possible. Every page lists its sources with retrieval dates.
  2. 2. Real quantities. You enter measurements — the calculator adds material waste, converts to billable units and multiplies by local unit prices.
  3. 3. Honest ranges. You get a low–mid–high range, not a fake precise number, because that's what real quotes actually do.
  4. 4. Quarterly refresh. Prices are re-checked every quarter and each page shows its update date. Estimates are for planning purposes only. Actual prices vary by project details — always confirm with on-site quotes from licensed contractors.
