Extensions- 8 Feb 2020
Absolutely brilliant. Andrea is so knowledgable, and her attention to detail is incredible. It’s really so reassuring to be able to leave everything to such a consummate professional, knowing that she can be trusted to raise with you any and all decisions in good time (even the most minor ones!). So relieved to have gone through such a big project with so little stress!

Bathroom Fitting- 7 Aug 2023
We asked Richard to remove our old bathroom suite and replace it with an ensuite shower (not a wet room). Richard listened to what we were looking for in our ‘dream’ shower room and gave suggestions on layout, design and tile styles and colour ways. He has a good eye for Co-ordination and made some great suggestions for wall tile and flooring ideas. Shower installed was of a high specification and is fabulous! Extractor fan and ceiling lights also installed. Richard is a hard working craftsman who does the job to a good standard. As with any construction work there was some disruption but Richard took our two cats into account when going in and out of our property. Yes it did get dusty but what can you expect when building works happen?! Richard finished the job and left our ‘site’ in a very clean state with all building materials removed. We’ve asked Richard to come back and renovate our downstairs cloakroom next. Highly recommend!

I chose Baladine because it is a small local company and has experience and knowledge of this area. The bungalow renovation has taken over a year to complete and inevitably there have been challenges along the way, which have been overcome on both sides with patience, humour and co-operation. I found the trades people skilled and efficient and would work with them again. Overall it has been an interesting experience and I would have no hesitation in recommending them or working with them again on future projects.

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.

Extensions- 11 May 2026
These guys are the real deal. So very impressed with the work that that have done. You can tell a lot about a building company with what condition they leave the building site and they left it spotless and very clean. Which lends itself to the high level of craftmanship they have put into converting my brick shed into a gym. Nothing is a problem for them and they turn up on time when they say they are and crack on with it. Mark offers recommendations for the work and due to this what I initially requested is even better than I expected. It has been a real pleasure having them on site and would offer them future work for sure.
