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

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.

Specialists in replacing roofs, slates or tiles. I source and supply all materials saving the customer time and hassle researching the materials. All of the materials I use are of the highest standard. I always supply samples of tiles or slates to ensure we get what suits best for your property and price range. I also do new build houses from wall plate to finish and fit fascia boards and soffits. Other jobs we regularly complete include full loft Conversions and replacement of old roof windows due to them becoming drafty or if they have been fitted for 25 years and over and need a upgrade. All of my jobs are completed to a high standard and come with a 10 year warranty.
