What Croydon Homeowners Say About Our Loft Conversion Specialists
L-shaped dormer extension on our 1930s semi in Croydon. Steel beam over the new opening replaced two existing partition walls in one go. Came to £85870 for the lot. Permitted Development application submitted by them, approved within 8 weeks.
Used BestBuilders to find a loft specialist near Croydon - two of the four quoters were FMB-registered, picked the most thorough one. Smoke alarms tied into the existing system - one less commission visit. Spec sheet was 14 pages long - left zero room for surprise extras. Final bill £46760. Snagging fully resolved within 10 days of completion.
Eighteen months in and we still cannot believe how much daylight that L-shape pulls in. Builder we found via BestBuilders in Croydon reused some original roof timbers as feature beams - a clever bit of design. Total £69640. Family of five now comfortable in a house we nearly outgrew.
