“All windows and a garden door replaced by a very knowledgeable 'crew', all of whom have been with the company for many years. That is something very rare these days, and speaks volumes. Could only recommend ALL of them.”

Window Repair Specialists and Glaziers in London
Average rating: 5 out of 5 stars17 February 2025
“Our project at High Wycombe was a challenging one as we were dealing with major delays due to contractor related issues. Despite these challenges, Dan who spearheaded his team of installers, led by Ben, showed a lot of patience and skill managing the difficult situation and made every effort to ensure that the installation went ahead with the required precision and quality that IQ Glass advocates. He went out of the way to help us with storage, extra site visits, and countless calls with the builders for advice on preparation for the precise openings. Thank you very much Dan! I would also like to thank Josh, Katie, Lottie, Scott and Steve for all their help and support throughout the project. I hope to work with IQ Glass again in the future.”

Glazier or Window Installer FAQs
Double glazing refers to the construction of windows or doors using two panes of glass separated by a gap. This gap, often filled with air or an insulating gas, provides better insulation compared to single glazing, improving thermal efficiency and reducing heat loss. Double glazing also helps to reduce external noise and enhance security. It is a common feature in modern homes and buildings, contributing towards your homes energy efficiency.
Specialist London window companies and fitters can diagnose problems and prescribe a choice of remedies while keeping in mind factors such as the style of your property, ease of operation, budget, noise reduction, thermal efficiency (the lower the U-value, the better), durability and maintenance. It is a balancing act that only a glaziers can deftly strike. Most London window companies will be able to take care of both supplying and fitting your new or replacement windows, but if you have already purchased your windows from a window manufacturer then you can find a London fitter to just take care of the installation.
Like most professions, window companies and fitters often have specialisms. The London glaziers you choose should reflect the types of new and replacement windows you are seeking, for example:
  • uPVC or PVCu window manufacturers will be able to assist in upgrading your windows with the latest technology. uPVC offers a cheap, energy efficient and low maintenance option.
  • A period window specialist will have particular expertise in how to deal with period windows. Together with his team of glaziers and joiners, can reinvigorate your period windows, help install secondary glazing, or provide authentic replacement windows.
  • If you are looking to add windows to your roof as part of a loft conversion then you should look for window companies with knowledge of roof windows or Velux windows. They will help you select the correct number of roof windows to maximise the light in your attic space whilst maintaining affordability.
