Extensions- 30 Dec 2021
Its been a pleasure having Albi and his team build our extenstion. Excellent job done (we had a 32 sq m extension for a new kitchen/dining room and the build was seamless). Good workmanship and genuinely easy to interact with. Albi kept to the timelines, offered good suggestions and delivered excellently. Albi and his team are reliable and provided a competitive fair price. They would be here early (7.30 - 5) 6 days a week and were a genuine pleasure to deal with. They were neat (even covering our drive with mdf panels to protect it from rubble) and then pressure washing it clean at the end. Works included Foundations Construction work Skylights Roof structure and roofing Windows/Bi fold door Exterior render Insulation Woodwork - doors, architraves, skirting Plumbing Electrics Plastering Paint Flooring (wood & tile) Tiling Installing kitchen
