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.

The team that worked on our build have worked extremely hard since starting and their attention to detail is excellent, the team really cared about the quality of their work which showed in the end result. They were always very friendly and tidy throughout the build, very pleased!

Excellent plasterer and renovator. Years of experience in all aspects of building works. Confident and competent to transform any property. Passion for gardening/maintenance of properties inside and out.To me the first impression is a lasting impression. Most small jobs can be estimated via pictures makes life simpler for most working people. 50% of the job as a deposit to secure a job and 50% when finishing Is usually expected. Of course there are Exceptions for different jobs. Thank you very much for reading have a fabulous day.

Kris from KPT Building was excellent. He was very prompt and worked quickly and neatly. He and a colleague took out our shower cubicle and fitted a new shower tray, replumbed the toilet and cleared a blocked pipe in the loft. It took less than 8 hours! He managed to salvage the old shower cubicle and refitted it perfectly. He was very efficient and we would highly recommend him.
