Tony is possibly the best option you have. He is genuine, trustworthy, a man of his word and prices competitively. Even if he isn't the cheapest quote you get you should still try to employ him as he won't let you down. He's been doing this sort of thing since he was a young lad, and even though he's still relatively young in the scheme of things do not be fooled, he knows his stuff. It has been an absolute pleasure having Tony do our extension, and I am very happy to have anyone over who wants to take a look to discuss the quality of his work before proceeding with him. And no, this is not a plant! I am just a very happy customer.

Landscaping- 1 Dec 2020
Arron and his business partner Mark were extremely professional in their approach, their work was "spot on". Customer Service was important to them and was delivered to a high standard. They were flexible too and willingly did those little extras that always seem to crop up. We'd not come across them before so were delighted with the above. Of course we would recommend them.

I had Stephen do many jobs for me, complete bathroom renovation, complete kitchen renovation, spiral staircase up into attic room creating beautiful underneath for storage, all which he designed himself. He plastered many walls and ceilings and laying wood flooring in my living area and replacing many doors. The work Stephen has carried out for me is outstanding, he is very professional in all duties of work. He is a very reliable worker, always on time and never missed a day. He is also a very clean worker which is important when customers are still using they homes to live In while work is being caried out. I would definitely recommend Stephen and will be using him myself in the future.

I originally booked multiple building companies for a quote for my home improvements. Carl was friendly on initial meeting and give me good explanation on how best to carry out my project with the maximum impact to use my space. He was very efficient in getting back to me with his quotes and I could clearly see the breakdown of each individual project. The timescales that he recommended were also managed within the given timeframe that was advised. The company was very clean and tidy and always made sure that any rubbish was taken and disposed of the same day. The quality of the workmanship was very good and I feel that the standard of finish for the end results were also very good.

Extensions- 15 Dec 2024
Fantastic company!!! From start to finish, Philip and his team have been friendly, polite and are clearly very experienced experts at what they do. Excellent industry knowledge enabled them to navigate some unforeseen complications with minimal fuss and cost. Finding a builder can be a very stressful process, as there’s a lot of choice and it’s probably the second biggest investment you’ll make, only second to the actual house itself. They’ve been absolutely brilliant, with almost daily updates on their progress and plans for what they’re going to do next. Made us feel very confident in allowing them to do what they do best without a single worry. Another thing to mention is the sheer speed at which these guys get the job done. Philip makes sure that he throws as many skilled men as he can at each stage of the build to ensure that it’s competed without delay. Does pouring the foundations on the second day on site sound like a great achievement?? It certainly does to me! Would recommend to anyone. Pick these guys, you’ll be glad that you did!

Extensions- 3 Oct 2022
The Guys were great, excellent work, put the hours in to get the job done, 99% of the work is done they're just coming back to install the windows once they've been manufactured. But the rest of the work, I can't fault it having had a terrible experience whilst building the house a few years ago these guys went above and beyond, and proved there are good builders around. Great attention to detail and skilled. Would happily recommend them and use them again on future building projects.

Plastering- 4 Sep 2020
Living room walls and ceiling plastered. Communication leading up to the job and during was great. Richard was great to deal with. Started first day and arrived early which is always a good sign. I went away for a few days whilst work being done and Richard kept me informed and sent through pictures and video. Really, really pleased with finish and can’t wait for it to dry out now. Cleaned up once finished too. Richard to come back to finish off once other works done and this hasn’t been a problem with him either. Would definitely recommend.
