Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!

Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

GMS

Cellar & Basement Conversion

Gareth, the proprietor of GMS is a qualified wood machinist by trade and has over 25 years’ experience working within the construction industry. Gareth first started the business in 2005 with a view to provide clients across North Wales and Cheshire with kitchens. In the last 10 years the business has diversified and now accommodates a scheme of works within construction from kitchens to bathrooms, gardens to bedrooms, fire and flood damaged properties and more. Gareth employs several staff and subcontracts to NICEIC registered Electricians and GAS SAFE registered gas engineers. Therefore, GMS can offer project managing and the client only needs to converse with one trade [GMS] rather than multiple. Thus, taking the stress out of the job.

We asked Valon to lay porcelain slabs along the border of our garden. He responded to our request quickly and popped around beforehand to view the garden. His quote was less than anyone else’s and despite allowing one day to complete the work, it took 1.5 days and he didn’t charge us any more. His workmanship was of a high quality and we would highly recommend him. He also undertakes building work as well as gardens so he will definitely be out go to person in future

Needed some internal work, including walls and chimney removal. Price was competitive and the work was excellent. Turned up on time, kept us informed and no hidden extras! Not only was the work first class he also took the hassle of building control, submitted the documents and when the inspector wanted an extra bracket for the chimney, he was there, as arranged 2 days later to fit it. If anyone is thinking of needing building work, make sure you include Kevin in your plans.
