Plastering- 16 Mar 2020
Almed and his team came over to see the two bungalows and gave me a quote and was more reasonable than other quotes I had previously. Almed started the job and stated exactly what he was going to do from the beginning to the end of the job. He is a very professional and knowledgeable person and he and his team did a outstanding plastering job on my two bungalows and I’m very happy with the job and will highly recommend him for future projects. Thanks Zai

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.

Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

Two rooms in one day. The work was done to a high standard and everything fit as it should. He left the job tidy and neat, when I walked into the room, it was if the floor had laid itself. We also hired him to install a double glazed window for us, again work done excellently and no less left

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.

A great experience. Work was completed quickly and to a good standard with an unexpected extra (sorting out the electrics for a light in the crawl space). Most tidy builders I have ever employed. Quick responses and good communication. I'd happily use Prime Contractors again

Extensions- 21 Apr 2019
The initial job was to complete a ground floor extension and house refurbishment. The job covered kitchen extension, underfloor and central heating, re-pluming, laying flooring, stair refurbishment, downstairs WC, patio, painting/decorating and much more then i can remember. I posted the job on Mybuilder and got several quotes from different firms. I was impressed with Dariusz as he requested the plans in advance of attending and provided a quote that was reasonable, before moving forwards I asked if I could see/visit a couple of jobs that Dariusz had completed recently which he arranged the feed back from ex-customers was excellent and the work was competed to a impressive standard. I was very impressed with Dariusz and his team, anything he was unsure of regarding the design he would ask before moving forward any surprises that cropped up with he dealt with, the team where clean and tidy. We are extremely happy with the work completed, guest that visit always mention the quality of the finish. I have recommended Dariusz to friends and family as well as use him for other jobs we have since planned. I would like to thank Darisuz and his team for all there hard work!

Handyman- 12 Oct 2018
The flat was left in a very bad state after the tenants left. Marius was able to undertake all the jobs, from changing carpets, redecorate, repairs and clean up. Also gave good advice as I was not able to attend the site in person so Marius kept me updated with photos. The price was also good. Thank you. Will use these guys again.

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!
