Luan did my flat roof with the new material EPDM. Luan did a clean, neat job and approx two years later the roof looks just as good and no leaks even after some heavy stormy weather. Luan will respond to any questions in a short frame of time and has a pleasant manner. However he does like plenty of English tea.

Luan and his team were excellent - they arrived early and set to work immediately, keeping everything tidy as they went. Communication has been prompt leading up to the work. Would highly recommend!

Luan has done a great job with replacing our garage roof. Good communication, neat and tidy and great work. I can thoroughly recommend using Luan for local building work. Thanks Luan, top work.

Leo and his team are excellent workers. Very thorough, neat and efficient. Leo has painted lots of parts of my house, fitted a new bathroom and also carried out many different maintenance jobs - roofing, plastering, guttering, etc. He is happy to help and I thoroughly recommend him and his team!
Client · Sarah Hargrave
I initially employed Luan to paint a couple of rooms after my pipes burst. Impressed with his work ethic and his prices,and then employed him to rip out a damaged bathroom and fully replace it. I fully recommend him to anyone looking at employing him - He is easy and fun to work with. Kept my close throughout the project informing me of issues and giving me enough information to make decisions when needed. He was tidy, polite, always on time, went out of his way to go to shops and find the right parts- very committed to the end result. I will be using Luan in my next project(s)!
