About HouseWarmth
Practical property insight for warmer, more efficient homes.
We turn a verified address and building footprint into an easy-to-understand attic insulation report.
Our purpose
Make the first insulation conversation more useful.
HouseWarmth gives homeowners and tenants a fast starting point before a professional site inspection. The result is based on the flat building footprint, with a map that can be adjusted when source data needs correction.
We do not claim to replace an on-site inspection. Instead, we organize the property information so the customer and contractor can discuss scope, R-value choices, and next steps with better context.
Responsible estimatesClear limitations and on-site verification reminders.
Property-specific dataReal footprint geometry rather than a generic calculator.
Comfort-focused planningSimple R-value comparisons for insulation decisions.
How data is used
A clear, three-stage measurement process
2. Find the footprint
OpenStreetMap is checked first, followed by Microsoft building data.
3. Build the report
Area, perimeter, property details, estimates, map, and PDF are prepared.
