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 job started as refurbishing a kitchen extension. Nik and his guys worked quickly and paid attention to detail. Nik came up with the best possible layout given the space. I liked the way he worked so he ended up refurbishing the whole house. He made use of the materials and fixed things that needed fixing as he went along all within the quoted price. A good honest team of builders that transformed the property.

I recently had Luke and his team widen an opening between two rooms in my property, which was a sizeable job requiring the installation of a steel beam. The work was managed efficiently, and great care was taken throughout the project. I’m very pleased with the results and would highly recommend Luke and his team for their professionalism and attention to detail.

A guy called Michael showed up, gave it all the large talk about what he would do. Gave him an address for another project also out of goodwill so he didn’t have to buy another lead. Promised to get back to me despite promising me he would return that week to do the work. Instead just ignored every phone call and message. He kept mentioning about wanting to do it in the evening…. This was impossible as it was a shopfront. Absolutely no balls, AVOID LIKE THE PLAGUE!

Andre and team did a great job with the shed /summerhouse construction, and were very accommodating with the request to build it at short notice ( (within 5 days) and alter the layout of the building to meet our requirements. Also were very friendly and professional. Reasonably priced too. Would recommend.

I contracted Alfie to refurbish a large area of Cotswold stone terrace and pathways around my home in Godalming. The terrace was a mess. Alfie and his team made a great job of removing all the old cement mortar pointing, relaying loose slabs, re-jointing and tidying up the area, including rebuilding the front door step. His young team were friendly, polite and hard working and I am happy to recommend them to anyone considering hard landscaping work. Everything was delivered to the agreed plan.
