What Crawley Homeowners Say About Our Garage Conversion Specialists
Single garage to utility room on our Crawley 1950s cottage. New steel beam over the new opening to the existing house. Came in £512 under quote thanks to a simpler floor build-up. Specified U-values better than minimum for thermal comfort.
Compared two FMB garage conversion specialists in Crawley through BestBuilders. Engineer signed off the new beam dimensions before the steel was even ordered. Final spec £25520. Skip changeovers timed for weekends, never an issue with the road outside. New room is the most-used part of the whole house now.
Eighteen months post-completion, no damp issues despite the original suspect slab. Builder we found via BestBuilders in Crawley persuaded us into a wider opening to the original house - flow is so much better. Total £29340. Working from home is so much better with the proper office light.
