Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!

Dmitry

Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

I had my timber casement windows refurbishment done by GW Windows and Glazing. They replaced all glass, sanded frames, new window furniture (fasteners and stays), putty and 3 coats of paint. I am extremely happy as the windows should last another 10 years before any future maintenance for 1/5th of the price for double glazing. Family run business with over 100 years experience combined between the team. Loved working with them. Extremely happy. Highly recommended for a reasonable quote.
