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!

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.

Specialists in replacing roofs, slates or tiles. I source and supply all materials saving the customer time and hassle researching the materials. All of the materials I use are of the highest standard. I always supply samples of tiles or slates to ensure we get what suits best for your property and price range. I also do new build houses from wall plate to finish and fit fascia boards and soffits. Other jobs we regularly complete include full loft Conversions and replacement of old roof windows due to them becoming drafty or if they have been fitted for 25 years and over and need a upgrade. All of my jobs are completed to a high standard and come with a 10 year warranty.

Ian came round to take a look at a damp patch that had started showing up on one of the utility room walls. He turned up on time, was really friendly, and clearly knew what he was talking about. He gave everything a proper check over and explained what was likely going on in a way that actually made sense. He didn’t try to make a mountain out of a molehill or push for any unnecessary work—just gave honest, practical advice on what to do next. Really appreciated how straightforward and helpful he was.
