WHEN REPLACEMENT MAKES SENSE

If more than 40 % of a frame has rot or the window has been hacked for uPVC, a hand-crafted replica delivers better long-term value. Benefits include:

  • 40 % + of the frame is rotten or already altered by uPVC.
  • Conservation officers allow like-for-like replicas with slim glazing.
  • Long-term energy savings outweigh restoration costs.

MANUFACTURE & INSTALLATION

Survey and measure → three-week workshop build in Lenzie → one-day fit per window across Helensburgh, Rhu, Kilcreggan and Dumbarton.
