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.

Messed me around for weeks and then on the day job was due to start, they said they couldn't come. Very disappointed in the level of service. Avoid.

From the very first conversation, Karl has been great to deal with. Any discussions about the job were clear and I felt confident throughout the time the job lasted. The project started on time and despite the weather the job was completed in good time. Plus an excellent result as well. Very pleased.
