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.

Very pleased with their service! Jason was great, he was the only plasterer to recommend different things to save both time and money with an excellent result. All the plasterers were a pleasure to deal with and worked very hard! I can't recommend them highly enough. They managed to get to us within a couple of days as we felt our job was urgent and even came out to quote on a Sunday! Very happy customer! Thanks all!

RS Property did a brilliant job on my bathroom; very professional and good communication with Roger throughout the project. I gave them a tight timeline and challenging materials and they worked well to get the job finished earlier than expected. They even took my bath and WC back to B&Q when they saw a small crack in them! Would highly recommend RS Property
