What Sunderland Homeowners Say About Our Loft Conversion Specialists
Velux-only loft conversion on our 1930s semi in Sunderland. Single large bedroom with vaulted ceiling and exposed steel beam over the new opening. Total £41200 over 11 weeks on site. Building control sign-off on the first inspection, no remedials.
Used BestBuilders to find a loft specialist near Sunderland - lead times varied from 6 to 14 weeks - we picked on availability not just price. Stairs were the tricky bit - reconfigured the landing without losing the family bathroom. Daily 5pm sweep-up, weekly progress meeting, never once felt out of the loop. Final bill £46480. EPC went up two bands thanks to the new insulation spec.
Six months on, the soundproofing on the new floor genuinely works. Builder we found via BestBuilders in Sunderland pushed back on the original architect drawings and saved us £4k of unnecessary steel. Total £50120. Stamp duty saved by extending up rather than moving up.
