Frequently asked questions
Can windows be replaced in winter or bad weather?
Yes — pros replace one opening at a time so the house is never fully open, and cold-weather installation is routine in cold climates. Sealants and foams have temperature limits, so extreme cold or rain may shift a schedule, but winter is often the quieter, cheaper season to book.
How much does window replacement cost?
Windows are priced per opening: the unit itself (frame material, glazing spec, size) plus installation labour. A standard-size replacement in an existing opening is the base case; enlarging openings, upper-floor access, bay windows and heritage styles add meaningfully. Whole-house jobs get per-window discounts.
Why is my double glazing misted up between the panes?
The sealed unit has failed and let moist air in. The fix is usually replacing just the glass unit, not the whole frame — a fraction of full replacement cost. Widespread misting across many windows of the same age suggests the batch is failing and full replacement may be better value.
How long does window installation take?
Replacing a window in an existing opening takes 2-4 hours per window for an experienced crew — a whole house is usually 1-3 days. The wait is in manufacturing: made-to-measure windows typically take 2-8 weeks from survey to fitting.
What should a window installation quote include?
Per-window pricing with glazing spec, removal and disposal of old windows, making good internal reveals and external sealing, hardware, and warranty terms for both the unit (often 10 years) and the installation. Cheap quotes commonly exclude making-good — the messiest part.
What is the Mandatory Window Inspection Scheme?
Buildings aged over 10 years can be served MWIS notices requiring windows to be inspected by a Qualified Person and repaired by registered contractors every 5 years. If you've received a notice, bundle any replacement into the compliance works.
