I highly recommend William Haykal. We hired him to renovate our entire 2 bedroom, 2 bathrooms flat, he’s done the job in just 19 days and the end result is simply stunning. His attention to details, craftsmanship, and professionalism exceeded my expectations. From the initial consultation to the final touches, he made the process seamless and delivered outstanding results. I couldn't be happier with his work!

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.

Coming from a family of plumbers and electricians, he was immersed in the construction industry from an early age. Over the years, he has refined his skills across multiple trades, including plumbing, electrical works, bespoke cabinetry and kitchen installations.

Conversions - General- 28 Jun 2026
We recently had our detached single garage converted into a fully usable room by Agron and his team, and we couldn't be happier with the result. The project involved replacing the garage door with matching brickwork, raising the roof, installing new windows and a door, insulating the garage, plaster boarding and skimming throughout, and rendering and painting the exterior. The work was completed to an exceptionally high standard. Agron and his team were fantastic from start to finish. They were incredibly friendly, professional and hardworking, completing the project quickly without ever compromising on quality. Communication was excellent throughout, they kept us updated on progress and always made sure we were happy with how the project was proceeding. They were also very accommodating and happy to adapt to any requests or changes we made along the way, making the whole process stress free. The attention to detail and pride they took in their work really shows in the finished result.

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!
