Restoration & Refurbishment- 23 Sep 2025
I would recommend them for similar work . It required the structural changes, overseeing plumber and electrician as needed and the carpentry, brickwork and kitchen fitting etc was all to a high standard. The workers were polite and respectful at all times.

Extensions- 24 Mar 2020
I was completely happy with the services that Jack provided. He was always prompt with communications and turned up when he said he would. He accommodated any changes to the design of our porch with no fuss, and made helpful suggestions for improvements. The price was very competitive and I have no problem with it, which came in exactly as quoted. The work was done to a very high standard, and we are really happy with the result. I would 100% recommend Jack and would definitely contact him again if we want any further work done.

Extensions- 21 Dec 2018
Well why can I say about Simon and his team..... From The moment we met Simon we knew he was the one to do our extension, he was laid back but knew what he was talking about. We sat down before the works began so that we all knew where we stood regarding cost, time and expectancy. The contact between him and both me and my partner was great, we had constant updates and new ideas thrown our way. Simon decided to change a few things from the original plans and this was definitley for the better and sailed through building control. His team were great, from the brick layers, roofers to the plumbers. His full time team of Doig, Olly and Luke were great - always polite, friendly and on time. They all did a great job and can't fault there workmanship. Nothing was too much trouble and we even asked simon to fit the kitchen aswell, which he did to a high standard. He will even fit u a cat flap if you ask him nicely :-) . Thanks all. Have a great Xmas. Xx

Extensions- 14 Dec 2017
Rob and his team were great! Without hesitation he gave us 3 references of extensions he had built locally to us all with glowing appraisals before we confirmed we were happy for him to start. He explained everything very well and was always reassuring. His timing keeping on our project even with small problems were spot on and actually finished 2/3 days before the agreed finished date. Rob and his team also supported us when we had issues with suppliers (which we sourced). Rob and his team were always polite, friendly and willing to chat over the phone at pretty much anytime. He have a dog and he was always very considerate of him during the build. I would highly recommend Belmax team and their 5 star work/service.

Conversions - General- 22 Apr 2026
Stu/GSP team have done an amazing job in converting part of our garage into a toilet and maximising the remaining space for a workshop and storage area. From the first visit we knew that Stu really understood what was required and he helped us come up with a design that was functional and achievable within our budget. Stu then delivered the build within timescales and with minimum disruption. During the work, Stuart's communication was first class, involving us in any decisions and ensuring that we were happy with the build at every stage. What impressed us most was the co-ordination of all the various jobs that needed doing - electrical, plumbing, regs etc. Even for a small job, there was a lot of "moving parts" and everything happened very smoothly from our perspective. The build quality is very good. GSP completely cleared away all the rubbish and we know that should there be any issues in the future, GSP will be there to fix them. GSP have a very satisfied customer. Thank You GSP.

Bathroom Fitting- 30 Sep 2015
Craig did an excellent job on our bathroom. The house is an old 1930s house and the old bathroom was pretty horrible. Craig (and his team), fitted the new electrics (extractor fan, towel rail), plumbed in the lot and skimmed the walls where required. The tiling is perfect. In fact, the whole finish is great. I was particularly impressed when Craig pointed out the defects in the bathroom suite we had ordered. Unfortunately the delay in getting the items replaced meant that he had to stay on the job longer than first thought, but that wasn't a problem. I will certainly use CLR Construction again if required.

Extensions- 1 Feb 2019
I have no building experience whatsoever and this was the first time I had ever had major works done on any property I owned. I had not used Prestige Builders before so as with using an unknown entity I was slightly apprehensive. I need not have been, they were very professional from the Start to the Finish of the Project. I liked the fact that they offered suggestions on how improvements could be made to my requests and ideas. All of their Staff were polite, nothing was too much trouble and they were always considerate to my Neighbours with regards to noise etc. The Job was completed on time, in budget even with me making some significant changes to my original specification and also adding to it as we went along. We are very pleased with the finished product and all my friends who have visited have made positive comments to the standard of the works. I would not hesitate in recommending them to any future customer and if I need anything else done , I will not look elsewhere.
