Extensions- 21 Nov 2021
Lewis and his team have been absolutely amazing from beginning to end. We wanted to knock through our dining room and kitchen wall to make a large family living space and utility area at the back of our garage. They supported us through all the drawings and building control regs. Always at the end of the phone for any advice. They remained on budget and on time, even when we asked for some extras to be done along the way Lewis was always happy to accommodate what he could. It was clear that his intention was not only to meet our expectations but to exceed them. We are very grateful for the hard work Newbridge developments put into to help us achieve the home we wanted. I would highly recommend them to anyone.

Groundwork & Foundations- 28 Nov 2025
I needed a 1.5ft deep and1 1ft wide French drain installed around the perimeter of my house to prevent bridging of the damp proof course. Karl has been absolutely amazing throughout, from the first contact where he was very responsive and described exactly what the work would consist of. When the work was done, Karl sent me photos (I live far away from where the work was being down) and a video, and the work was done to an incredibly high standard. I would highly recommend Karl, and he will now be my go-to person for any groundwork jobs that I have in the future.

Plastering- 19 May 2026
Mike has just plastered my bedrooms, bathroom and hall and stairs ceilings. I have no hesitation in recommending him to other people. It was refreshing to have somebody who is conscientious and arrives on time. He always replies when you leave him a message and the quality of his work is excellent. I found his costs to be very competitive and nothing is too much trouble. I have already recommended him to my daughter and one of my friends and will contact him again when I need more work doing.

Conservatories- 24 Jul 2025
I posted the required work for my conservatory roof and received interest from 11 companies. My conservatory is relatively big and a very odd shape. Out of the 11 companies, 4 would not undertake the work, 4 would only work on renovating the current roof, and 2 just didn’t take on board my request quoting something totally inappropriate. Scott came to view the job and was confident in being able to meet my requirements and expectations. He talked me through the work that would be involved and how he would achieve this. His openness, honesty, and guidance gave me the confidence to choose him to undertake the work. He arrived ahead of the scheduled date and got down to work straight away. He kept us informed every step of the way with what was happening, completing the work in the agreed timescales. Scott and his team did a quality, first-class job on the new roof, which I am extremely satisfied with. I cannot thank him enough for what he did and would wholeheartedly recommend him.

Handyman- 7 Mar 2021
I would highly recommend Dan Wright without hesitation. Dan was extremely helpful before my job started, suggesting solutions and messaging beforehand to ensure everything was on track. On site, Dan was hardworking and adaptable, another job came up while he was here which he negotiated there and then and added to his list, he worked efficiently and fast, advising along the way and nothing was too much trouble. If, like me, you are dubious of finding the right handyman, rest assured you really won't find anyone better, he even got my 17 year old son helping out which is saying something! 😁. You really won't regret appointing this guy!
