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!

Carpentry- 17 May 2026
Raghbir did an excellent job and completed the work on time, exactly as agreed. What stood out most was his honesty and professionalism there were no hidden charges or unexpected costs, which can often happen with some tradesmen. He also didn’t cut corners and delivered quality workmanship throughout. I would highly recommend him for any carpentry work.

Conversions - General- 14 Oct 2018
Noel and Dan did a very good job converting our shed into an office. They were always on time, were very good at communicating, and always cleaned up after themselves at the end of each day. There was a problem with an electrician who let them and us down - prolonging the job by a few weeks. However, their own work was excellent and to time, and we are enjoying the fruits of their labour. I would very happily recommend them (although perhaps not the electrician!).
