Bradley worked on my house extension doing all the brickwork professionally with high quality workmanship. Upon completion I asked Bradley to stay on independently and lay my patio with surrounding brickwork. Again a superb professional job.

Extensions- 19 Apr 2024
We greatly appreciate the professionalism and quality of workmanship by Ian and the build team over the Winter in completion of our extention. The team worked hard to make sure there was minimal disruption to the lives of my elderly parents during the build and showed flexibility in additional out of scope carpentry and steelworks. We are completely delighted with the overall vaulted ceiling ensuite room extensions.

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.

Conversions - General- 28 Jul 2023
From the first day to the last during 3 weeks Jack and his team were consummate professionals. They worked around us respectably as a family with young kids and involved us in decisions that some builders might consider minor (location of sockets, radiator, colour of brickwork etc), explaining their progress every step of the way. Unlike some builders they stayed almost every day to see our project through, and at the end our garage conversion we saw it was is everything we dreamed of and more. Thank you we couldn't have expected better.

Latest review:
Andy built a large single story extension at the back of our house in 2013. It is a contemporary design with two sets of large bi-fold doors, two roof lights with a modern rubber roof and zinc fascia. The work included laying a new patio and tiling inside also. A number of internal walls had to be removed so quite a complex job. This is the fourth project that Andy has completed on our house - prior works were bedroom and office extensions, wall removal in kitchen and exterior retaining wall. I have always been delighted with Andy's work hence using him for all of our projects on this house. He is very skilled, sets very high standards for both himself and any trades he brings in, has an amazing work ethic and is a builder that you can trust. I am more than happy to be a reference for Andy.
