Conversions - General- 29 Sep 2022
The job - gutting our living room. Tearing down the ceiling, removing all old wallpaper and ripping up the floor in order to insulate and add lighting. While we were doing this, we decided to replace the main steel in the living room (which was oversize and impacted the floor height in the guest room) and do remedial works in the guest room. The steel replacement was not time budgeted, but Oli and Tony didn’t hesitate to quote,To make time for us and bring in the structural engineer. Probably added 3 weeks to their time on site. The trades they brought in (plumbing for heating, electrician for downlighters, structural engineer and plasterers) were all professional, did an excellent job and were all unfailingly polite. It was easy to build a good, positive relationship with them, to the point we felt comfortable giving them the keys to the house so they could work while we went away for two weeks. They sent photos of their progress and showed up and worked as if we were there. I was very impressed by the state of the house when we got back. They watered our plants (I didn’t ask) and they cleaned the hallway so that it was spotless. They did a good job for a fair price, and were always cheerful and open to conversation. They came back to do a few snagging items without being chased (this is a huge thing for me, after having chased many builders to finish bits and pieces). I would definitely use them again.

Extensions- 29 Sep 2020
Kevin and his team are without a doubt the best bunch of workers you will ever meet. They work around the clock to keep us on target for the build dates. Their work is perfect and they left us with a a tidy site once they were finished. If you are having any work being done then give these guys a shout. Just keep them going with Coffee and a greggs sausage roll and they will just keep working. Happy to show you their work if you want. Thank you Kevin, Dave and Al. You made our dream home a reality. Will call on you again when we extend the kitchen 😀

Groundwork & Foundations- 21 Aug 2026
Excellent Builder I would highly recommend Louis. He was very polite, professional and really cracked on with the job from the start. He worked hard and did his absolute best to fix the poor and unfinished work left by the previous builder. His attention to detail and attitude were excellent, and I really appreciate the effort he put in. Great job, Louis!

What qualifications and experience do you have as an extension builder in Wallingford?

An extension builder in Wallingford should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Wallingford extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Wallingford?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Wallingford extension builder’s ability to deliver a result that meets your expectations.
