Arwel stood out from the other contractors who applied to do the job because he visited before quoting and made some additional recommendations. He replaced guttering, some loose root tiles and also recommended that we use some protective edging that he also installed. Roof looks great.

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.

Very pleased with the work done, entire large garage roof replaced, Jordan and the team were very professional and hard working, got the job done sooner than expected as they worked longer days to get it done for us. Jordan took time to listen to our needs and our budget and did his upmost to keep the costs very affordable, without sacrificing on the quality of the work. Each day they ensured everything was clean and tidy. Would highly recommend and definitely use again if needed. Very happy customer
