Landscaping- 16 May 2024
We hired Albion Groundworkers to take on our garden and driveway project. They are a very hardworking bunch of guys who do not slack when it comes to quality! They arrived everyday on time and worked extra to make sure the job was completed in the estimated timeframe. Armir was my main point of contact and he was always there to answer questions and provide advice where necessary. They were very mindful of my neighbours and ensured the site was left clean and tidy before leaving. It is a family run business and they take a lot of pride in their work. I would highly recommend anyone to use them and I have already had so many compliments from family and friends!

Restoration & Refurbishment- 5 Apr 2025
Where do I begin? So Alex and his team has pretty much renovated two flats including external work such as roofing. The work involved was quite challenging as the building has a lot of damp / mould / leaking issues. Alex’s attitude towards resolving every matter was exemplary. He would take his time to explain his strategy to tackle each and every problem in a very metholodical way. I have never seen anything like it. I am so pleased with Alex’s work and so are my tenants who live in the flats. I would highly recommend Alex, especially for tougher jobs!

What experience do you have with similar extensions in Middlesex?

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