"We interviewed four builders for our rear extension. One lowballed, two wouldn't commit to a timeframe, Hartwell gave us a proper quote with a Gantt chart. Came in on time, on budget, spotless site throughout. A rare thing."Rachel Armstrong · Southborough, TN4
"Full re-roof in eight days. Warranty paperwork in my inbox the next week. Properly professional."
"Loft conversion with ensuite. Added £60k to the valuation. Would use them again for the garage next."
"Re-pointed our listed cottage. English Heritage-approved mortars, matched perfectly. Faultless."
Fifteen years on the tools before starting Hartwell in 2008. Today the team's four strong — a lead carpenter, a bricklayer, a roofer and James running the jobs himself.
Federation of Master Builders membership means every job is independently vetted. CompetentRoofer registration means our roofing work's signed off without separate LABC fees. Every extension comes with a 10-year structural warranty.
We turn down more jobs than we take. It's the only way to keep the work right.
