Restoration & Refurbishment- 15 Feb 2020
I found Craig to be a great bloke from start to finish. Turned up promptly to look at and quote for the job and was early on both days when working on it. His workmanship and quality is first rate and the attention to detail is fantastic. He is very tidy as he works, cleaning as he goes. Would recommend Craig and have no hesitation in using him again.

Extensions- 11 Jul 2018
I decided to build a garden room and received a number of quotations from various builders. I decided to go with Rod Hall of Lux Building Services for a number of reasons. 1. On meeting Rod me and my wife felt very comfortable and Rod discussed our plan in fine detail, in addition Rod introduced ideas of his own which had no cost implication but did in fact improve the final plan. 2. Rod was very fair and honest with his costings and this was confirmed at the completion of the project (no hidden costs). 3. Rods attention to detail and work ethic was outstanding and kept me and my wife informed throughout the project. 4. The materials used were of the highest quality sourced at the best price so we had no complaints. All in all a pleasure to have had Rod take on our project and we are more than pleased with the results......a very good job to a very high standard. I would without a doubt recommend Lux Building Services to family and friends. Pete.

Tiling- 8 Jan 2026
While this tradesman appeared to know what he was doing, he didn't. He requires 50% upfront which should have set off alarm bells, but he said he needed that for the materials. When I pointed out issues with the job, he became aggressive cornering a lone female tenant in the bathroom demanding payment or he would rip everything out of the bathroom. I paid as I was frightened for the safety of the tenant and I was managing the job remotely. I only viewed the job in person today and the workmanship is terrible, he didnt even fix the leak coming down the back of the bath, he put so much silicone around the extractor fan (due to cutting the panelling too short), that the electrician cannot get the extractor out to fit a new one. The panels he fitted have been cut too short with the gaps stuffed with silicone, which doesn't adhere to the bath so water leaks out. Do not use him

We got a cracking good job from Andy and his team on our 1st floor extention in Longbenton. They were all reliable good tradesmen and nice lads to deal with. Andy also had good ideas while doing the work and any extras that we wanted were swiftly dealt with. We would gladly recommend Andy and his team to carry out any building project for clients and we also found Andy's estimates for our building project to be very competitive. We would certainly use him again for any future work on our property.
