Question 4

What is secondary glazing and why choose it?

Accepted Answer

Secondary glazing involves installing a discreet internal window that sits inside your existing window frame. It's ideal for heritage properties where external changes aren't permitted, offering up to 70% noise reduction and 20% improvement in thermal efficiency. It's particularly popular in conservation areas like Mayfair and Kensington where planning restrictions apply. Prices start from £350 per window.

Question 5

How long does a window installation take?

Accepted Answer

Standard luxury window installations typically take 1-2 days per window depending on complexity. Heritage sash window restoration can take 3-5 days per window. Full architectural glazing projects (skylights, glass roofs) typically require 2-4 weeks including planning, fabrication, and installation. We work discreetly around your schedule to minimize disruption.

Accepted Answer

We install electrochromic smart glass that transitions from clear to opaque at the touch of a button, perfect for privacy without curtains. We also offer self-tinting glass that responds to sunlight, heated glass for winter condensation control, and switchable privacy glass for bathrooms and offices.
