Kitchen Fitting- 7 Jul 2016
Excellent! We hope to use again! I cannot recommend Alex & Richard highly enough. We had a full kitchen/diner knock through and complete refit. They were an absolute pleasure to have working at our house. From the moment they came round to quote for the work, they were pleasant, prompt, clear and concise. They were able to start work quickly which was great for us. The professionalism and attention to detail was amazing. Always arriving on time, they often stayed late to complete their work which lasted just over 2 weeks. They are a credit to the building industry and themselves. Our finished kitchen/diner looks amazing. We are so pleased. Please do not hesitate to hire these guys - you won't be disappointed!

I was recommended Bear Construction by a friend, and it turned out to be an excellent suggestion. From the initial consultation with the architect to the final handover, Bear Construction provided an exceptional experience. Here are the key highlights of working with them: Smooth and Transparent Communication: Each step of the process was clearly explained, and I received daily progress updates, which I found incredibly helpful and reassuring. Respectful and Considerate Team: The work site was kept tidy and well-contained. My neighbours also mentioned how respectful the team was, which was especially important as my property is mid-terrace. Impeccable Quality and Efficiency: The project was completed to an exceptionally high standard, and impressively, it finished three weeks ahead of schedule. I couldn’t be more pleased with the results and would happily recommend Bear Construction to anyone seeking reliable and high-quality building services.

James provided a fair quote and delivered the project within the agreed budget. He kept the communication channel opened all the time, with constant updates about the progress and next steps so we knew exactly what to expect across the whole project. He was reachable through Whatsapp and happy to answer all our queries. He delivered a good quality job and we are very happy with the outcome as he managed the whole project including dealing with building control. I’d highly recommend him.

Extension Builder in Alton, South East England
I'm 48years old, English. I've been a builder for over 28 years. We mainly do extensions. We have built plenty of houses from start to finish over the years. But now prefer the slightly smaller jobs. I'm easy to talk to, and have lots of ideas if that's what you need.

Extensions- 1 Feb 2019
Extremely satisfied. He happily goes the “extra mile” and his charges for such additional work are reasonable. Inevitably the odd unanticipated item arises in the course of the work and he discusses the options rather than making up our minds for us. His dictum that he does not leave a job for another before the first job is finished is reassuring - and fact. We have been happy to contract further work to him - including hard landscaping - on the completion of the original extension work, and are equally impressed with his performance in this.

Landscaping- 26 Jun 2026
I'm really pleased with what Jason and his team did with my patio. It was a complete mess with weeds growing everywhere. They cleared them all, lifting slabs when required, pressure washed and grouted. They also did a really nice job of changing the outer line by removing some. They were polite and efficient, and really reasonably priced. I'll be asking them back to do my driveway in the near future. Fully recommend.
