Retrofit Double Glazing for Lancaster properties
The hard part of Retrofit Double Glazing in Lancaster is not the making, it is the measuring. Local property is overwhelmingly cotton-town terraces, Pennine stone cottages and Fylde coast resort stock, which is why we never quote from a catalogue. Set against high rainfall inland and severe wind exposure on the Fylde coast, most joinery here eventually shows wind-driven rain penetration at meeting rails and sill joints. The part that matters is reworking the rebate so a sealed unit fits without bulking the section.
Nothing is ordered until someone has stood in front of the opening with a tape. Tell us the problem rather than the solution and we will advise on both.
Local factor worth flagging early: coastal Fylde stock needs the same specification discipline as the South West.
