Retrofit Double Glazing for Darwen properties
Half the Retrofit Double Glazing problems we fix in Darwen started as a sizing assumption. Given the cotton-town terraces, Pennine stone cottages and Fylde coast resort stock that dominates locally, standard sizes are the exception not the rule. The exposure here is high rainfall inland and severe wind exposure on the Fylde coast, which is exactly the condition that causes wind-driven rain penetration at meeting rails and sill joints. In practice that means reworking the rebate so a sealed unit fits without bulking the section.
Manufacture only starts once the survey figures are agreed with you in writing. Tell us the problem rather than the solution and we will advise on both.
One thing that catches people out here: coastal Fylde stock needs the same specification discipline as the South West.
