Painting & Decorating- 13 Nov 2025
The team did a solid job on our extension. They were on time, kept the place organised, and stayed easy to reach throughout the project. The extension came out exactly as agreed and the finish looks clean. They also took care of a few extra jobs for us, including painting the exterior, laying new slabs in the garden, and putting down new grass. The whole place looks tidy and well put together now. I would be happy to use them again.

Joinery & Cabinet Making- 9 Dec 2024
Very impressed by Eugene's work. I hired him to build a bin shed for my front garden. He took the time to understand what I wanted and work out how he could combine the look I was after with a stable structure. I am so pleased with my new shed. Eugene is trustworthy and reliable and I will hire him for other work in the future

He started the job but went away without finishing it just because he couldn't fix the hinges, which wasn't a rocket science. I would never hire him again.

We did not go ahead with this job as we did not purchase the property, however, Craig and his team phoned me and explained to me over the phone what is needed and provided me an estimate over the phone which is what I was looking for. This helped me and put in to context what I was dealing with. Thanks very much.

What experience do you have with similar extensions in Hatfield?

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 Hatfield extension builder’s ability to deliver a result that meets your expectations.
