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.

A prompt response from Luke. A thoroughly decent Chap...

My names Tom, I have been in the real estate sector for over 10 years and have done everything from general property maintenance, new bathrooms, painting/decorating, demolition contracts and most recently constructed 9 ultra high spec homes. High quality and impeccable workmanship are key values to me and ensuring the client is satisfied and more with the work they are receiving. I have decided to further expand and diversify my business reaches and so my rated people account is new, however my experience in the industry is far from that. I am very well connected with all trades and can provide a top tier service for all types of project management no matter how big or small the job may be. I am also extremely capable at doing many manual labour jobs, but often favour a shorter timeline for my clients project completion and therefore prefer to draft in experienced trades to get the job completed. Above all I am very friendly, well spoken and always keen to deliver what is asked of me.

John worked extremely hard to fulfil our brief & also had great vision when considering possibilities. He understood our needs and ensured all snagging was carried out before completion. All builders are currently pushed to the limit with supplies and staffing - John managed this to the best of his ability and was always polite, helpful and friendly.

I didn't actually give the job to Smart Construction; but Aaron visited to inspect the job, and was extremely helpful, personable, and business like; he also did some research to work out the structure of my property. In the end, another firm was able to start earlier than Aaron thought they could - I'm very happy with progress; but think it's well worth speaking to Smart Construction, and wouldn't hesitate to contact them in future, if I need building work done (which I really really hope I don'tj

David, Adam and the team they employed were very good. They talked through every aspect of the job beforehand and made the costs clear in the contract. The construction was of a high quality and all done efficiently. This construction was completed during lockdown and the team adapted and communicated well throughout the process. Everyone who worked on the job was polite and friendly and professional. During the construction there were minor changes needed which were accomodated well, even after completion.
