FAQ
Frequently Asked Questions
Quick answers to the most common questions about window and door replacements.
How much do new window installations cost?
Prices vary depending on frame material (uPVC or aluminium), size, style, and glazing (double or triple). Contact us for a free, no-obligation quote and site survey tailored to your home and budget.
What is the difference between double and triple glazing?
Double glazing features two panes of glass with an insulating gas layer between them. Triple glazing adds a third pane for higher thermal efficiency and stronger noise reduction — ideal for busy South East and London streets.
Do I need building control permission to replace my windows?
Yes, replacements must meet thermal insulation and safety glass standards. As a FENSA-approved installer, Lux Windows handles compliance and registers your certification after installation.
How long does a typical window installation take?
A standard domestic replacement is usually completed by our certified fitting teams within 1 to 2 working days, keeping disruption to a minimum.
Do your installations come with a warranty?
Yes. All Lux Windows uPVC and aluminium installations come with a comprehensive 10-year warranty, plus an insurance-backed warranty for extra peace of mind.
