What Basingstoke Homeowners Say About Our Loft Conversion Specialists
Dormer loft conversion on our 1970s detached in Basingstoke. Sound insulation between floors took the noise from upstairs to inaudible. Came in at £75500 across 14 weeks. Twelve-year structural warranty in writing on the new beam.
Used BestBuilders to find a loft specialist near Basingstoke - three quotes within 48 hours, all itemised properly. 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 £60200. Stamp duty saved by extending up rather than moving up.
A year on, the new loft bedroom is the favourite room in the house. Builder we found via BestBuilders in Basingstoke flagged a hidden joist problem early and budgeted for it before contracts. Total £65800. EPC went up to a B - the new insulation spec made all the difference.
