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.

They were quick to respond and to provide a reasonable estimate for how much the work would cost. Once we had confirmed the job, they were flexible in working around our dates. The work was done promptly and our tenants were very satisfied with the quality. A great job all round.

My name is Max Akkaya and my company started with plumbing and bathroom refurbishments after graduating from my NVQ level 2 course in Heating and Ventilation. In the last 20 years we have evolved into One Stop Design and Construction Ltd - a fully insured company that covers all aspects of home improvements such as loft conversions, extensions and bespoke refurbishments. I haven’t been on Rated People in a while as I have got all my work through recommendations, however I recently moved to Surrey so I am building my client base out here also. I’m straight forward, honest and pride myself to giving attention to the smallest of detail. We undertake small and last scale projects and work with a team to deliver loft conversions, extensions and bespoke refurbishments including all plumbing, electrical and gas needs.

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.

With many happy and returning customers over the last 10 years, you can be sure of being well looked after. Our aim is to provide a stress free project, delivered in a manner that I am confident will exceed your expectations. I work with a small team of trusted colleagues, who communicate and work together well.

We got Kingston Surrey Construction in to undertake a full ensuite refurbishment after too many leaks and drips over the years. They provided a competitive quote and were available to undertake the work quickly to suit our needs. They worked at a steady pace with a focus on doing it right rather than doing it quickly. Their communication was good and they were as tidy as you can be with such a job. Overall we are very pleased with the outcome of the work, many thanks.

John and the team did an outstanding job. It was easy to work with John and he was very knowledgeable, and provided very sensible advice. Other people quoted work which was over-the-top or wouldn't have solved the problem but John got right to the issue in a no-nonsense way. Quality of the work undertaken was very good, considering the age of the building and complexity. Would recommend.
