Frequently Asked Questions
Is there really a best month to start a renovation?
For external work, yes. Extensions, roofing, rendering and external insulation all slow down in heavy rain, and some materials need a dry curing window. Freeze-thaw cycles also damage wet mortar. For internal-only work like kitchens and bathrooms the month barely matters, pick whenever suits your household.
How recent is the weather data?
The data comes from the Open-Meteo archive, which pulls from Met Office and ECMWF observations. I average the last four years of daily readings for your postcode, so the result reflects current climate, not 30-year averages that may be out of date.
What's the recommendation based on?
A simple scoring function: low rainfall and temperatures near 15°C score highest. It finds the best three-month window. For most London postcodes that lands in April to June. Your actual window shifts based on your location.
