Tiling- 24 Sep 2025
I hired seasouth builds because not only did he give a really reasonable quote, but he also had knowledge of tiling over retrofit underfloor heating - which other tilers seemed to be really hesitant to work with. The job was done to an excellent standard - he’s a real perfectionist. It did take a bit longer than expected, due to some floor level issues which he didn’t account for when he quoted. I was really worried about the price increasing out of my budget when we started running over time, but I was so grateful to find that he was a really honest guy who stuck to the agreed quote and didn’t try to make it my problem one little bit. He was polite and friendly throughout the whole job, turned up whenever he said he would, and kept in constant contact. Really honest (I happily left him unattended in my property). Customer service was excellent, nothing was too much trouble. 10/10 would recommend.

Please avoid this company for many reasons. There work is absolutely shocking and the owner is incompetent and should be ashamed of himself how he left my job. I’ve tried to contact Elijah and he’s blocked me, he’s an absolute disgrace. I will put up pictures of his work so you can see how bad his work is.

Extensions- 29 Nov 2023
We had the most fantastic experience with Sarunas. He was highly professional from start to finish and completed the work to the highest standard. We extended our project significantly once we realised how excellent he was and he has now renovated our whole home over an 18 month period. He was able to guide us through the process and help us make key decisions which made the experience smooth and efficient. He is extremely skilled in all aspects of building, has high attention to detail and is a pleasure to have in your home! I couldn't recommend him higher and look forward to having him back in future to convert our loft!

The refurbishment of my small one-bedroom flat took approximately 2.5 months. I compared several builders before starting the project. The price was not the cheapest and the proposed timeline was not the shortest. Though Radilina seemed to be a good project manager and liked that she works on a fixed price for each work.

Carpentry- 31 May 2017
Was really impressed with these guys. Helped me order the correct garden door and then went to pick up extra bits when the order didn't turn up correctly, for no extra cost and couldn't have been nicer about it, even though it was a pain for them. Really cheerful and helpful - nothing was too much trouble. Would use them again, for sure.

Extensions- 8 Dec 2021
Me and my wife are very satisfied with Prabbuilders work. What stands out with Prab builders is that they do every task as if they are doing it for their own house and with work they are meticulous and exceptional. What we started with and how our extension looks now is simply amazing and the way they explain about what will look good(Color/ the structure etc ) is commendable as we both were not sure what decision to make, but after completion we are overjoyed to see how excellent it turned out to be now. I would recommend them anytime based on their skill ,eye for detail, being punctual and the hard-work they invest into every task to make sure we are getting the final product the way we dreamt of.
