Gas Work- 7 May 2019
Jason was a breath of fresh air. He is highly professional, totally ethical and has great integrity. Unlike many engineers who took no time in quoting me for a brand new boiler,Jason checked the boiler to accurately ascertain what precisely was wrong with it in order to determine whether a new boiler was necessary at all. He identified the problem to an external loose valve above the boiler which was leaking. He kindly tightened the valve and stopped the leak. My sincere thanks to Jason for saving me in excess of £3000.00!

Restoration & Refurbishment- 28 Apr 2024
I highly recommend these people if you want to be fleeced, taken advantage of, treated appallingly and work left unfinished. The standard of work is below average. If you want high quality finishing do not come here. I’ve had to spend a lot to redo a lot of their mistakes and mess. If Jerzy could charge you for every single nail he would, so beware. And when you challenge, they get aggressive and nasty. Very unprofessional. Do yourself a favour and keep away. So thanks Jerzy and co for a load of stress and rubbish. I am happy to talk to anyone and advise against these people.

Extensions- 26 Sep 2022
Excellent work with the garden office/gym. Finished really nicely and exactly what we were looking for. Took quite a while but well worth the wait. We requested a labour quote and worked with Alf on a receipts basis for material and other costs. This worked out perfectly for us both. Alf's initial estimate of the materials cost was virtually spot on, which is very impressive given the inflation rate for building materials. Thanks again for all your hard work!

Extensions- 6 Oct 2022
I was lucky enough to have Haroun on this project of side extension and outside building. He is such a professional guy and always committed to do his work up to the standard. He has been very nice to us and always responded whenever asked to do additional jobs. He is very honest and trustworthy and his team has been very wonderful. I'm very happy with work he did in the house and would hire him again should the necessity arise in future.
