Reviews, straight from Google.
"James did our rear extension over 10 weeks — finished on time, on budget, and the site was tidier every Friday than some of our friends' kitchens."
"Our roof had been patched for years. Hartwell stripped and re-tiled the whole thing in 8 days. Warranty paperwork arrived the next week."
"Loft conversion with ensuite. Clear quote, no surprises, added £60k to the valuation. Couldn't fault them."
James Hartwell spent 15 years on the tools before setting up Hartwell Builders in 2008. Today the team's four strong — a lead carpenter, a bricklayer, a roofer and James managing every job.
Federation of Master Builders member. NFRC Roofing. CompetentRoofer registered. £5m public liability. 10-year structural warranty on every extension.
