Frequently Asked Questions
What does the Complete Renovation Works include?
The Complete Renovation Works is the most comprehensive window refurbishment option, building on the Four-Treasure Works (replacing hinges, handles, internal and external sealant strips and silicone waterproofing) with full-flat waterproofing. Refurbished old windows achieve results comparable to new ones, at a more affordable cost.
How much does the Complete Renovation Works cost, and is there a warranty?
The Complete Renovation Works starts from about HKD $2,000 per window, depending on the number and condition of windows, and comes with a 3-year waterproofing warranty. After an on-site assessment the technician provides an itemised, transparent quote with no hidden charges.
Complete renovation or full window replacement — how do I choose?
If the frame is still structurally sound, complete renovation (accessory replacement plus full waterproofing) achieves results comparable to new windows at lower cost; if the frame is deformed or badly damaged, or you want a different style, a full aluminium window replacement is better. The technician advises based on the actual condition.
