What Boston Homeowners Say About Our Loft Conversion Specialists
Mansard-style loft conversion on our 1990s townhouse in Boston. Single large bedroom with vaulted ceiling and exposed steel beam over the new opening. £69930 across 13 working weeks. Building control sign-off on the first inspection, no remedials.
Used BestBuilders to find a loft specialist near Boston - three site visits in one week, all quotes back by the following Monday. Re-routed the existing soil stack inside a vertical chase to keep the elevation clean. Lived in throughout - they tarp'd the staircase opening every night. Final bill £59920. EPC went up two bands thanks to the new insulation spec.
Three years post-completion, zero issues, no creaks, no draughts. Builder we found via BestBuilders in Boston suggested moving the en-suite location to keep the daylight in the bedroom. Total £62280. Stamp duty saved by extending up rather than moving up.
