Slim Cavity Glazing for Welwyn Garden City properties
Slim Cavity Glazing is one of those jobs in Welwyn Garden City where the survey decides everything. Property here runs to garden city stock, Georgian market town frontages and commuter-belt detached housing, and each of those brings its own set of dimensions. With moderate rainfall with cold inland frosts in the mix, frost damage to end grain and swelling on unbalanced-finished units is a question of when rather than whether. The value is in getting a sealed unit into a historic sightline without bulking it out, not in the timber bill.
Manufacture only starts once the survey figures are agreed with you in writing. 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.
