What Sale Homeowners Say About Our House Extension Specialists
Rear and side extension combined on our detached new-build in Sale. Two-storey gain - utility on the ground, en-suite bedroom on the first. Cavity-tray detail done properly. £73960, staged invoicing against milestones. FMB-credentialed builder, structural calcs done in-house.
Compared four extension builders through BestBuilders for the Sale job. Selected on availability rather than price - we needed to start before winter. Sub-trades all booked in advance so no waiting between phases. Came to £80790 fitted plus the £1086 party wall fee. Moved out for two weeks during the demolition and steel install, the rest was bearable.
Six months later, no settlement cracks anywhere - foundations were clearly done right. Builder we found via BestBuilders in Sale spotted that the existing kitchen waste was undersized and corrected it as part of the works. Total £63660. Decided to stay rather than move - the extension solved the space problem entirely.
