Plastering- 23 Dec 2016
Denis did a good job plastering and retiling a small area of my kitchen. He responded to my ad promtly, came round the next day to quote and carried out the work 2 days later as requested. He was professional, polite and left my kitchen clean and tidy after the work was done. I'm happy to recommend him and would contact him again if needs be.

Piotr's work is really good. I did four or five kitchens with him and I did recommend him to him to another builder friend of mine and they are happy with his work - no complaints. He arrived on time so there were no delays. I too am very pleased with his work and would of course use him again when I have some stone work to be done.

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
