Retrofit Double Glazing for Blackburn properties
Getting Retrofit Double Glazing right in Blackburn depends on detail that a price list cannot capture. Most of what we survey locally is cotton-town terraces, Pennine stone cottages and Fylde coast resort stock, which is not built to any modern module. With high rainfall inland and severe wind exposure on the Fylde coast in the mix, wind-driven rain penetration at meeting rails and sill joints is a question of when rather than whether. In practice that means reworking the rebate so a sealed unit fits without bulking the section.
The survey happens before manufacture, which is why our units fit without packing or trimming. Rough dimensions and a couple of photographs are enough for us to price it properly.
Worth knowing locally: coastal Fylde stock needs the same specification discipline as the South West.
