Real reviews from Leigh & Co customers in Burgess Hill and the surrounding villages — left on Google by homeowners we fitted kitchens and garden rooms for.
Google Reviews · Burgess Hill
“Leigh and the team fitted our Howdens kitchen around a chimney breast no other fitter wanted to touch. Scribed perfectly, the quartz island is seamless, and they hoovered every afternoon. Genuinely nice to have in the house.”
“We needed a proper home office, not a shed. The garden room is warm in January, cool in summer, and the cedar looks better the rainier it gets. Worth every penny.”
“They beat our Wren fitting quote and the joinery is noticeably sharper. Curved units, undermounted sink, all the electrics signed off. One team, start to finish — no subcontractors.”
“A proper room at the bottom of the garden — bifolds, full glazing, wired for everything. Leigh talked us out of an expensive mistake on the orientation too. Honest advice, rare thing.”
“Tidiest builders we've had in the house in 20 years of renovations. Fixed price, no surprises, and the painted shaker looks stunning against the oak floor.”
“Our walls are famously wonky and the curved cream units are scribed so cleanly you'd never know. Granite templated on site and fitted the same week. Faultless.”
