Why location matters
One country choice controls currency, units and local cost adjustment
A Dallas, Texas estimate is shown in US dollars and uses the Texas state planning factor. A Manchester estimate is shown in pounds sterling and uses the North West England regional factor. City selection labels the market; it does not claim a separate city price. There is no currency selector to mismatch.
United Kingdom
GBP estimates, metric units and regional labour multipliers covering England, Scotland, Wales and Northern Ireland.
United States
USD estimates, US customary units, all 50 states plus Washington, DC, and major cities in every state.
Quote-ready scope
Each result is paired with cost drivers and a checklist so competing contractor quotes can be compared on the same scope.
Editorial standard
Useful estimates, not false precision
Home improvement prices vary with labour availability, access, permits, taxes, product choice and hidden conditions. Our ranges are intentionally broad enough to be honest, with the assumptions stated beside each calculator. The result is a planning figure, not a binding quote.
