Jack came and quoted to lay a new patio and a shed base. He listened to exactly what I wanted (something other workmen didn’t do!) and came back with a very reasonable quote and said he would complete the job on a weekend as I wanted it done asap. From start to finish Jack was really polite and friendly and worked really hard to get the job finished - so much so, I’m adding more bits to the garden and will get Jack back over to do it!

Extensions- 31 Jul 2026
Dan, is an immense organiser, everything on site runs like clockwork. He’s neat and tidy, and cleans up daily. The tradesmen he hires are top notch and all love working with him. The job is well thought out from start to finish and he considers your needs throughout as well. For example we had a kitchen extension and he made sure at the end of each day we had running water and a hob! Very courteous. He keeps you well informed of what’s going on day to day, and presents exemplary work before the building inspector. Lee, his right hand man, is equally as thorough and they make a wonderful team. Every aspect of the build is well thought out. All of the materials arrive on time. Tradesmen are booked in advance and are always punctual. Our build ran like clockwork. We had progress chats every evening on the phone and the plan for the days ahead. Dan likes to keep you well informed of everything going on, and will give expert advice on any snags throughout. Would 100% recommend him.

Extensions- 10 Sep 2019
Do not hesitate to use these guys. Nothing is too much for them. Rob and his team built my kitchen extension and I am over the moon with the work. Rob is a perfectionist and from day 1 was personable, professional and 100% trustworthy. The plumber, electrician, bricklayer, tiler and carpenter that were used were top class. They all made the whole process so easy. I would wholeheartedly recommend this company and their team. If you would like to come and have a nose, just let the company know and I am happy to show you their work. Any changes that we made along the way were taken on board and everything is perfect and exactly as we wanted. The guys never cut corners. Thank you for our beautiful extension. It has changed the way we live for the better.

Bathroom Fitting- 9 Feb 2019
Andrew did a fantastic job in installing a new bathroom floor and bath suite. As the bath had leaked below, he also replaced the ceiling. The quality of work is fantastic, whilst at the same time cleaning up after completion of works. I would definitely hire Andrew again as the standard of work is incredible.

What experience do you have with similar extensions in Hertford?
