Extensions- 10 Jan 2017
I couldn't be more happy with the porch that Dave & James built for me. I have a character property and had a very specific idea of what I wanted and they got it spot on. They were extremely sympathetic to the original cottage and my new addition looks like it has been there forever. I decided to go with an Oak front door which James fitted and it's perfect. I was very pleased to see both Dave and James turn up each morning before I headed off for work so that we could have a catch up. I really, really appreciated this gesture. The work was completed on time as promised. I will most definitely be using David James Construction in the future with the landscaping of my front garden being the next project. I am so pleased to have found reliable, skilled and trustworthy tradesmen who I know I will go back to time and time again. Thank you ever so much Dave & James!

Extensions- 1 Sep 2021
I have nothing but praise for Michael and his team. The project was managed exceptionally well and Michael kept us apprised of progress, emerging issues (which were dealt with quickly and with some innovative thinking) and he was honest and candid with our choice of kitchen tile (I think his words were do you want to rethink that colour!). Michael quoted in Nov and started work in the Spring (late Mar) and held his price despite a national increase in the price of materials and reduced availability which he managed admirably. Obviously a man with a good eye; his suggestions for additional works were inspired and they have resulted in a high quality finish. Finally, it is worth mentioning the team who did the grafting! Very industrious, skilled, polite and helpful. Highly recommend Wooburn PM to anyone considering building work. :-)

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

An extension builder in Bletchley 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.

What experience do you have with similar extensions in Bletchley?

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