How long does it take to fit double glazing?

The installation of double-glazed uPVC windows and doors can significantly enhance a home’s energy efficiency and value. The process usually takes between one to three days, depending on several factors:

  • Removal of Old Windows: This initial step involves taking out existing windows and preparing the openings for new units.
  • Installation of New Frames and Glass Panes: New uPVC frames are installed, followed by the fitting of double-glazed glass panes, often to replace old windows such as sash windows.
  • Variables Affecting Time: The number of windows, their sizes, the complexity of the designs, and any custom specifications can extend the installation period.
  • Extra features: If the job is more complicated, such as when you’re fitting a conservatory, this can extend the time by quite a lot.

How much do uPVC windows and doors cost?

The cost of uPVC windows and doors varies widely based on several factors including the type, size, and specific features of the products, as well as the complexity of the installation process. Here’s a more detailed look at the potential costs involved:

  • Price Range for uPVC Windows: Typically, individual uPVC windows cost between £150 to £900 each. The wide range in prices can be attributed to differences in window sizes, styles (such as casement, sash, or tilt and turn), and the glazing options chosen (double vs. triple glazing).
  • Average Costs for a Standard Home: For a typical three-bedroom house, replacing all windows with standard white uPVC casement windows might cost around £4,000. This price includes both the cost of the windows and the labour for installation.
  • uPVC Doors: Prices for uPVC doors start from around £500 and can go up to £1,200 or more for enhanced security features, bespoke colours, or glass panel inserts.

Additional Cost Factors:

  • Installation Complexity: Costs can increase based on how easily accessible the windows or doors are, and whether any additional structural modifications are needed. For example, enlarging an existing window opening or converting a window into a door will add to the cost.
  • Geographic Location: Installation costs can also vary by region, with urban areas and the south of England typically having higher rates due to increased labour costs.
  • Customization: Custom colours, unusual sizes, or special patterns in glass (like frosted or tinted) can significantly increase the price. Additionally, enhancements such as noise reduction technology or high-security locks will also contribute to a higher cost.
  • Energy Efficiency: Higher-specification windows with advanced energy-saving features, such as argon gas-filled units or low-emissivity (Low-E) coatings, while more expensive, can provide substantial savings on energy bills in the long run.

Find your perfect fitter today

How do I know if the job has been done well?

To ensure high-quality installation of uPVC windows and doors, look for the following signs:

  • Sealed Joins: Check that the joins between the glass and frame are tightly sealed without any gaps.
  • Energy Efficiency Rating: The windows should have a low U-value, typically around 1.3-1.5 W/m²K, indicating good insulation.
  • Reduction in Energy Bills: Over time, you should notice a decrease in your energy costs, reflecting the efficiency of the new installations.

The best way to ensure a job gets finished properly is to take a look through previous reviews, as well as ask to have a look at old work. At Rated People, you can make the right choice based on a tradesperson’s past reviews, and read through our window fitters page to find out the types of questions you should be asking beforehand.

Other uPVC FAQs

Is it illegal not to have a FENSA certificate?

A FENSA certificate is required for new window and door installations as proof of compliance with building regulations in England and Wales. Not having one can be problematic during property transactions.

Is double glazing fitted from inside or outside?

Double glazing can be fitted from either inside or outside, depending on the property structure, the type of windows, and the preference of the installer.

How messy is window replacement?

Window replacement can be quite messy, involving the removal of old frames and possibly some minor building work. However, professional fitters will ensure that the area is cleaned up after the installation.

HEX360 was founded in 2015 by Craig Lewis with the solid foundation that a degree in construction management provides. Before launching HEX360, Craig’s former life saw him working at Princess Yachts, where he founded his skills and acquired his particular attention to detail – but if you’ve reached this page, you probably aren’t interested in hearing Craig’s life story… you’re really interested in finding out what makes HEX360 different to all the other construction companies out there. So read on and discover our difference. Working with most construction companies can feel a bit like finding your way in the dark – you just don’t know where to go to get the information you need. The stereotypical construction company that makes matters so confusing and complicated that everything they say goes over your head is, unfortunately, not just a myth. They’re out there, and they’re confusing clients as we speak. So, it’s no wonder that so many people put off their project or come to a grinding halt partway through – after all, it can all feel just too overwhelming. Luckily, HEX360 is here to change your perceptions and prove that not all construction companies are the same. We’re dedicated to working with you, not for you, and that means taking a collaborative approach right from the get-go. With our 8-step process, we’ll clearly outline every stage of your project so you won’t feel overwhelmed, and thanks to our use of in-house project management software, you’ll have complete transparency for every aspect of your project. We are committed to flexibility, accessibility, and approachability so your project can run smoothly, whether you’re updating your kitchen, renovating or extending your entire home or developing a large commercial property. You’re more than a number on a spreadsheet to us, and we never bite off more than we can chew. Our attention and efforts are solely dedicated towards you and your project during your time with us. Unlike with some construction companies, once we begin work on your project we don’t simply move on to our next. We provide industry leading account management during the full life cycle of the project, meaning you aren’t forgotten about once you sign on the dotted line.
