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.

After initially posting for a small garden job at home, instead spontaneously requesting a quote to inspect the condition of a roof on a commercial property. Jesse recommended installing replacement rain goods. These works led to the discovery of a serious issue, that he and his team were immediately able to address, using incredibly high standards of workmanship, culminating in a substantial roof upgrade. Jesse and his team were professional, courteous and extremely tidy. I am delighted with the outcome.

Bellhurst Construction gave me a very detailed quote and were able to start the job promptly. Darrel worked with me on adjusting he quote in order to prioritise the things that needed the most attention. We were held up a few days by the weather initially, but once things were underway I was very happy with how things progressed. The team were polite and worked hard through some of the hottest days of the year! The end result is wonderful and really makes the most of the garden.

DO NOT EMPLOY THIS BUILDER!! He has laid my wood flooring onto carpet without my knowledge and now the floor is ruined. He took on the job even though he wasn't qualified or capable of given that he told me he was,and has then stated that I told him to lay down the wood flooring onto carpet. I can CATEGORICALLY deny that. He now will not answer my calls to discuss this. UNPROFESSIONAL, RUDE AND A LIE.
