GMS

Cellar & Basement Conversion in Gwynedd

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.

I apologise for not having posted a rating before now. I thought I had already done so. Our loft conversion has transformed how we live.The cost was fair. The work was carried out to a good standard, quickly and tidily with minimum disruption. We are happy with the result. The "Boys" were friendly and easy to have about and full of good advice. I would use Roy again and have already recommended to others.

Following some work done successfully in 2022 by this company, I reached out to have some similar work done in 2024. However, I paid a deposit for the work, the job was never started, communication stopped, despite me reaching out via phone and email, and I never received my deposit back.

Second bathroom was ripped out and left unfinished because he had an accident (different stories) and no backup crew.
