Used BestBuilders to find a loft specialist near Cowes - final pick was the team with the longest workmanship guarantee. Dual-purpose handrail to the new staircase doubles as the loft balustrade. Daily 5pm sweep-up, weekly progress meeting, never once felt out of the loop. Final bill £59640. Loft now genuinely feels like part of the house, not bolted on.
A full freeze-thaw cycle later, no movement around the new dormer cheeks. Builder we found via BestBuilders in Cowes incorporated soundproofing properly - we no longer hear anything from upstairs. Total £49160. Estate agent re-valued the property up by 19% with the loft included.
