Bricklaying- 13 Jul 2025
Excellent completed work from Walid. Friendly, fast and polite communication with every question I asked, the work was booked in quickly and completed, and Walid even added in additional work when I asked him, with very fair pricing. I highly recommend Walid and have asked him to quote for some new work.

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.

Roofing (Flat)- 15 Apr 2016
An honest builder, came an inspected the roof and advised that not the whole roof needed replacing, only the section that was damaged needs to be replaced (other builders who inspected the roof advised the whole roof would have to be replaced) Quote received within 24 hours and once this was accepted gave me a start date. Email received the day before start date that his team will be on site the next morning. Received photos of the roof before and after, very pleased with the job. I will keep his contact details in my diary, will always approach him first for any building work required in the future.

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!

Conversions - General- 30 May 2013
Dave Phillips was brilliant. Friendly and accommodating, nothing was too much trouble. He converted our garage into living space, always solving the small problems builders face as they make progress. He has a really good network of reliable specialists for electrical, plastering...etc, all of whom he has known for decades. A perfect example of excellent small business. I have already recommended him to our friends and family, as a result he has lots of new business keeping him busy. Our friend's house needed full refurb, some very serious work, and Dave was available on the phone 24/7 when not at their house. As soon as we can afford to do more work on the house, Dave will be our first choice builder, in fact, we will wait until he is available to do any future work on our property.
