What Blackburn Homeowners Say About Our Loft Conversion Specialists
Velux-only loft conversion on our 1960s semi in Blackburn. Velux Cabrio openings double up as a balcony when fully extended. Came in at £72500 across 14 weeks. Twelve-year structural warranty in writing on the new beam.
Used BestBuilders to find a loft specialist near Blackburn - lead times varied from 6 to 14 weeks - we picked on availability not just price. Soundproofing the new floor was a priority and the spec they used genuinely works. Skip changeovers timed for weekends, never an issue with the road outside. Final bill £57400. Stamp duty saved by extending up rather than moving up.
Six months on, the soundproofing on the new floor genuinely works. Builder we found via BestBuilders in Blackburn suggested a wider staircase opening - a small change with a big impact. Total £62600. EPC went up to a B - the new insulation spec made all the difference.
