Window Installation & Replacement in Whampoa Garden

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.

uPVC/vinyl is the value pick: good insulation, low maintenance, mid-range look. Aluminium gives slim frames and durability (thermally broken frames fix its insulation weakness) at a higher price. Timber looks best and suits period homes but needs maintenance and costs most. Warranty and installer quality matter more than brand marketing.

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.

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.

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.

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.
