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.

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.

In total 4 ridge tiles were broken, old tiles kept to show us the fault. New tiles in place and look very good. Extra work requested on the conservatory to fix leaks, still waiting to see if this has worked, but feel confident. A very good job done in the required time.

M&A Property Specialists LTD is a family run business covering all aspects of Joinery and Building works. We thrive on the quality and finish of the projects we undertake. We have our own architects and structural engineers who provide all the required details for extensions, conversions and new builds. APL also organise all site visits with building inspectors to give customers peace of mind and a hassle free service. At M&A we use our own 3D CAD system in order to design any new kitchens we are to supply and install, we can include these in to Architecht plans to give you a visual of the room once completed. All our kitchens are high standard and all our doors we use are FIRA gold approved, we mainly use painted doors but if you want a more of a budget door we can use the vinyl wrap doors. About myself: I have been in the Joinery and building industry for 20 years with a huge vast experience in all trades and I know what to expect from various tradesmen from a finishing point. All electrical work and gas work is all completed by approved and qualified tradesmen. My main trade is joinery but in the 20 years of being in the building game I have gained the experience in each aspect in the building game which has its advantages when project managing a job whilst being on site working. M&A look forward to providing competitive quotations for our customers and working with yourselves as we have just came back to rated people. Payments to M&A can be made via Bank transfer, Cash or Credit/Debit card

Nigel visited us to assess the work and quote for the job. He turned up on time and was pleasant to deal with and answered all our questions. He also contacted us prior the starting the job to arrange a date and time. Unlike other tradespeople he turned on time on each of the 3 days it took to complete the work. The work was of a high standard and we were kept informed of progress as the work progressed. I have already began a discussion with Nigel regarding another project.
