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!

Bathroom Fitting- 25 Nov 2020
Alex provided a great service. He came round on time to view the job, gave a detailed and competitive quote and built the bathroom exactly to spec. He was keen to ensure I was happy with all aspects of the installation with regard to both materials and workmanship and even carried out some small additional activities not included in the original quote. He was polite, hard working and very experienced. He also cleaned up the house at the end of each day. I am really pleased with my bathroom and would thoroughly recommend him to anyone.

CAD / Drawings- 20 Aug 2019
I hired Mr Simon Javens of JavensDesign and found him to be very professional and able to turn around a difficult planning application accurately and quickly complete with fully CAD design specifications. He is willing to go the extra mile to liaise with third party agencies, be it the Council or previous structural surveyor(s) and architect(s). A very pleasant chap indeed. You will not regret hiring his services. I received excellent advice in every step of the journey - Simon is very knowledgeable and willing to help. I would recommend him 100% and will definitely use him again. Thank you Simon!

Extensions- 31 Aug 2024
BS Loft Conversions are reliable, honest and operate with integrity. I recommend them to anyone who is looking for some building work whether they are big or small projects. They arrive on time, work hard and leave the site clean and tidy. Anxehlo always takes the time to answer any questions we may have and talks us through the process before providing us with all the options available from repair, replacement or re-instatement. As a novice to a huge development, it was difficult to find builders you can trust but, Anxhelo made that process easier, restoring our faith in construction work.

Restoration & Refurbishment- 2 Apr 2026
Really pleased I chose Leigh Matthews for this job. We were taking over a building that was unoccupied for 18 months and there were some issues with that, The team were excellent, and they finished the 4-week job on time, and right on budget. They were helpful and considerate and left the premises clean and tidy. They were also able to help out with some problems with the plumbing that were not in the original scope. I loved the way they did the estimate and the invoicing. Breaking all the items down into the individual tasks and at the end of each week, itemising which tasks were complete and a %age on those in progress. I would not hesitate to employ them again
