Extensions- 17 Mar 2022
Tom presented a very reasonable but competitive quote and we hired him to build a storm porch (half stone, with oak joinery) for the front of our house. We are delighted with the outcome of the work, which is constructed to a very high standard (stonework wall, reclaimed tile double-hipped roof, concrete slab/step, and oak frame). Tom and his colleagues were very friendly and polite, consulted us at every decision point, and always responded to questions. Particularly important for us, they always turned up when they'd arranged to do so and informed us if they were going to be delayed. They also left the site clean and tidy promptly following the completion of the work. I would recommend Tom highly and would be very happy to engage him again.

Extensions- 10 Jan 2020
The weather wasn't too kind to Liam and Owen in the Autumn months when they were digging out the footings for our new extension, but despite the occasional delay they still managed to get on with it. Both Liam and Owen were polite and always turned up when they said they would early in the mornings. Having got the walls erected and roof on Liam liaised with the man to lay the floor screed and also the window fitters. There was a delay on one window as we wanted a bespoke window which has been made and fitted, it's exactly what we wanted, the bi-fold doors look amazing too. Liam and Owen cleared up after themselves each day, Liam arranged all the skips and rubbish clearance too. Now that it's finished, the extension will provide a huge benefit to us and we can't wait for the summer to come to put it to its full use. Bet you don't get so many cups of tea at the next job Liam! Thanks again to Liam and Owen.

Kitchen Fitting- 31 Jul 2025
I recently had my kitchen done by Ian, and I couldn’t be happier with the results. He was punctual, respectful, and worked to an exceptionally high standard throughout the project. What really stood out was his honesty—he gave thoughtful, practical recommendations that improved the overall outcome without pushing unnecessary work. I’d highly recommend him to anyone looking for quality craftsmanship and trustworthy advice.

Extensions- 1 Apr 2017
Rob and the boys did a fantastic job with our extension. We had an existing galley kitchen, and we wanted a porch/extension at the end to complete it. Rob was very flexible with changes and explained everything in simple terms to a building novice. It took around two weeks with some less than ideal weather conditions, yet this didn't massively affect progress. I also had some other work going on with the house, some of which impacted Rob, however nothing was too much of an issue. Very trustworthy, punctual, polite and does a fantastic job - couldn't ask for more really. I'll be using you again, Rob, thank you very much.

Repointing- 24 May 2026
I can't recommend Tony enough for the various different jobs he has done on my rented property. Not only has he completed them all to a very high standard but he has also provided me with regular progress updates both by message and by video and has always responded to my questions promptly. He initially responded to a request to sort out the rendering on my external wall but has subsequently mended a gutter, organised re-plastering, identified and corrected a bathroom leak, fitted an internal bannister and replaced broken glass in an internal door. He is a landlord's dream!
