No. 12684765 Working in Harlow ## What it's like fitting glazing in Harlow Harlow is the most architecturally distinctive area we work in. Frederick Gibberd's master plan delivered a town where modernist 1950s–1960s housing dominates, and original Crittall-style steel-framed windows are still in service on a meaningful proportion of properties — much of it now in serious need of replacement. Modern aluminium replacement frames replicate the slim sightlines of the original Crittall installs without the cold-bridging or corrosion. We've done this kind of replacement repeatedly across CM18, CM19 and CM20. Old Harlow and parts of Sawbridgeworth are conservation areas where character must be preserved — careful timber-effect replacements are usually the route. Harlow Council is the local authority.

What we see locally ## Common double glazing problems in Harlow Patterns that come up specifically because of Harlow's housing stock — typical property age, build style, and local exposure. ### End-of-life Crittall steel windows Original Harlow Crittall is corroded, cold and frequently single-glazed. Slim-frame aluminium is the modern equivalent that respects the original look. ### Flat-roof rooflights leaking at flashing Common on 1960s extensions where the flashing was never properly dressed. Re-detail at the time of replacement is essential. ### Cold-bridging on original 1960s frames Single-glazed steel frames lose huge heat. Replacement A-rated argon units transform thermal performance and dramatically reduce condensation. ### Listed/conservation restrictions in Old Harlow Old Harlow conservation rules limit external changes. Careful timber-effect replacement is the usual route — we'll confirm what's permitted at survey.
