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.

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.

Chris and John and crew were hard working and brilliant. They turned up on time and made light work of putting in double steels making sure everything was done. When building control requested added work, they had no problems getting it sorted. Hard working team cleaned up each evening. Great job. Price was reasonable.
