Loft Conversion- 20 Jan 2026
I have chosen Byron and his company to complete my loft conversion. Job was completed within given time frame. Byron and the team were polite and hard working. During the building time, any issues found by myself were addressed and rectified as much as possible. At the closing weeks of my project, I have asked Byron to complete additional carpentry tasks. He found the time to accommodate my requests. Job had some messy stages but Byron was always trying to leave site clean as much as it was reasonably possible. Thank you for your work and I would be happy to hire you again in the future.
