What Crawley Homeowners Say About Our Loft Conversion Specialists
L-shaped dormer extension on our 1970s detached in Crawley. Sound insulation between floors took the noise from upstairs to inaudible. Came in at £75800 across 14 weeks. Crash deck during construction kept the rest of the house liveable throughout.
Used BestBuilders to find a loft specialist near Crawley - two of the four quoters were FMB-registered, picked the most thorough one. Architect, structural engineer and party-wall surveyor all coordinated by the contractor. Three trades on site at any time but the foreman ran the schedule like clockwork. Final bill £60480. Acoustic floor performance has solved the upstairs noise issue.
Eighteen months in and we still cannot believe how much daylight that L-shape pulls in. Builder we found via BestBuilders in Crawley flagged a hidden joist problem early and budgeted for it before contracts. Total £66120. Loft is now the favourite room in the house bar none.
