We recently had Landi around to quote on a number of jobs we needed doing around our house. We booked him to fix our roof, which was leaking water - he and his team did an absolutely fantastic job. They were responsive, thorough and did a great job. We won't hesitate to recommend him to anyone and get him back for any work we need doing.

Restoration & Refurbishment- 13 Aug 2019
David and his team were excellent. They are always on time and very professional. They always cleared up at the end of the day thereby leaving very little dust or dirt around the house. No query or issue was ever insurmountable; the answer was always "no problem", which was a joy to hear when having such a large project to do. Each different team i.e. electrician, plumber, arrived exactly on schedule so there were never any delays. The end result was amazing. I highly recommend David and his team.

Extensions- 14 Feb 2021
Adam and the DJ Russell team have been great, I cannot recommend them highly enough. The job started on the 3rd of November 2020 and was completed on the 3rd of February 2021. All the neighbourhood have been impressed with the speed and accuracy of workmanship displayed. From the general builders (Bruce, Martin and Steve) to the brickies (Paul, Matt and Steve) and to the carpenters (Paolo and Dominic) through to the electricians (Max and his team) and the plumbers (Mark and Jack) and last but not least the plasterers (Gary and Craig) they all have kept me occupied with producing huge quantities of tea and coffee (-: but most of all they have constructed a quality extension for our home. Thank you for all your hard work and professionalism.

What experience do you have with similar extensions in St Albans?

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