Cliff, he was efficient, reliable, well priced and an excellent tradesman. We called him in to repair a chimney breast and fix our garage which was leaking. We were delighted with the work on the chimney, he is a fantastic render and plasterer. cliff is now renovating our bathroom, plus our neighbours are also putting him to work. An added bonus is he is a good communicator so he was able to work with our two very different personalities with different ideas, Cliff took it all in his stride.

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.
