Frequently Asked Questions
Do you offer free quotes for window and door installations?
Yes. All quotations from Glitz Windows & Doors are completely free and come with no obligation. We’ll visit your property, take accurate measurements, and provide a detailed written quote. Contact us to book your free survey.
Are your windows and doors FENSA registered and compliant with UK building regulations?
Absolutely. All our installations are carried out by FENSA-registered fitters and comply with current UK building regulations, including Part L (thermal performance) and Part Q (security). You’ll receive a FENSA certificate upon completion, which is required for conveyancing purposes when selling your home.
What types of windows do you install in the Coulsdon and Croydon area?
We install a full range of window styles, including casement windows, sash windows, tilt-and-turn windows, bay windows, and bow windows. All are available in uPVC, aluminium, or timber-effect finishes with A-rated double glazing as standard.
How long does a typical window or door installation take?
Most standard window or door replacements can be completed in a single day. Larger projects — such as full house re-glazing or conservatory installations — are typically completed within 2–5 days depending on scope. We’ll give you a clear project timeline before any work begins.
Do you install bifold doors in Surrey and South London?
Yes. We supply and install aluminium bifold doors throughout Coulsdon, Croydon, Sutton, Caterham, Epsom, and Crawley. Our bifold systems are available in a wide range of powder-coated RAL colours and are thermally broken for year-round energy efficiency.
