Retrofit Double Glazing for Welwyn Garden City properties
Retrofit Double Glazing in Welwyn Garden City is rarely a catalogue job. Because the area is mainly garden city stock, Georgian market town frontages and commuter-belt detached housing, no two openings measure quite the same. moderate rainfall with cold inland frosts is the local complication, and frost damage to end grain and swelling on unbalanced-finished units is what it eventually causes. In practice that means reworking the rebate so a sealed unit fits without bulking the section.
Nothing goes into manufacture until a surveyor has checked each opening on site. Tell us what you are working with and we will put a fixed figure in writing.
A local consideration we always raise: garden city areas carry design codes that restrict window style changes.
