I was very pleased with Jez - his quick response to the posting and clear communication. He came the next morning and finished the job very quickly. His invoice was clear and less than expected. He was reliable and more helpful than he needed to be, following up with really detailed information over email about some things that were discussed during the job. Quick, reliable and someone we feel we can trust with more work in the future.

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.
