I have used Steven on 3 occasions now and his work is exemplary. He has rebuilt my back wall which was in danger of falling down! He has replaced my bay window roof that was leaking due to all this rain. And he has built me a new back gate. Steven is punctual, hardworking, clean and tidy. He doesn’t stop even when it’s cold and raining…or for a cup of tea!! He’s coming back to look at another job for me. I would highly recommend Steven for future work.

Extensions- 30 Dec 2018
As first-time developers, we were nervous about employing builders. If you are in a similar situation, Roy is your builder. Price-wise, he was in the middle ground of the quotes we received, but he is a complete perfectionist and the work throughout the project was of an impeccable standard. Most importantly, Roy came in absolutely on-budget. We did go slightly over, but only because we changed our mind on certain things during the project- underfloor heating (if you haven’t budgeted for it, it’s a must!). Roy’s contractors are all incredibly committed, turning up when they say they will (even Sundays) and tidying up after themselves. Equally, they were considerate with the neighbours and great with our young son. Our build presented many challenges for Roy and his team, however these were all dealt with the minimum of fuss and intrusion. Roy was always happy to answer queries, no matter how obscure and kept us informed throughout of any issues. Despite several obstacles, the work was completed on time as well. I can say with complete sincerity, that I will happily recommend Roy and would definitely employ him again for any future work.

Bricklaying- 6 Apr 2024
We are extremely pleased with our new front wall. The end result reflects high quality workmanship and true understanding of the issues that affected the original wall. Regular communication before and during the job keeping us informed of the project and deliveries. Our neighbours were equally impressed with the end result and the work completed by Woodgate Construction. Highly recommend.
