Very happy with Rimi. He at all times came up with ideas and solutions. We had a rear garden job. Involved brick work, decking, retiling, soil work,painting, creating new landscape overall. He did it professionally and in time. He was patient with delays in material supply and kept following up. Overall quite pleased with the end result

Needed some internal work, including walls and chimney removal. Price was competitive and the work was excellent. Turned up on time, kept us informed and no hidden extras! Not only was the work first class he also took the hassle of building control, submitted the documents and when the inspector wanted an extra bracket for the chimney, he was there, as arranged 2 days later to fit it. If anyone is thinking of needing building work, make sure you include Kevin in your plans.

Fatjon / Tony and team did a fantastic job decorating my house, getting rid of damp and giving my front garden a completely new look. They re built wonky walls, rendered them and laid some amazing tiles giving an original Victorian look. Communication was excellent and there were no surprise / hidden costs at the end. All the guys at Bardhi construction were super friendly and extremely respectful of my house. They cleaned up every night and took great care of my property. I highly recommend :)
