FAQs – uPVC Windows in Gloucester & Gloucestershire
How many years do uPVC windows last?
High-quality uPVC windows usually last 20–30 years. Their lifespan depends on the standard of installation, the type of uPVC used, local weather conditions across Gloucester and Gloucestershire, and how well the windows are maintained.
What’s the best time of year for window replacement?
Many homeowners choose spring or summer because of the milder weather, but uPVC windows can be replaced throughout the year to match the style of your home. The right time depends on your schedule, the condition of your existing windows, and how quickly you want better insulation and comfort.
How much should a uPVC window cost?
The cost of uPVC windows is influenced by several factors, including:
- The style of the window (casement, sash, bay, tilt-and-turn).
- The size and shape of the opening.
- The glazing type and energy performance level.
- Frame colour and finish.
- Security features and hardware.
- The condition of your current frames.
- Installation complexity and access to your property.
Is it worth replacing 20-year-old double glazing?
Yes. After around 20 years, windows often show signs of ageing such as weakened seals, reduced insulation, condensation between panes, or draughts. Modern uPVC windows offer much better performance, and our service includes a comprehensive guarantee, so replacing older glazing improves comfort, security, and energy efficiency.
What is the 25% glazing rule?
The 25% glazing rule refers to the idea that windows, including uPVC frames, can account for around a quarter of a home’s heat loss. Because glazing plays such a large part in energy performance, upgrading older windows, can make a noticeable difference to warmth and running costs.
Should I replace 20-year-old windows in the winter?
You can replace new windows in winter. Installation times are managed carefully to keep heat loss to a minimum, and the benefits of new energy-efficient uPVC windows are often felt immediately during the colder months.
What is the most affordable way to replace windows?
The most cost-effective approach depends on factors such as:
- Choosing simple window styles.
- Sticking to standard sizes.
- Using standard frame colours.
- Replacing multiple windows in the same installation.
- Keeping existing openings intact to reduce additional work.
How long does installation of uPVC windows usually take in Gloucester homes?
A straightforward installation of window frames takes a few hours per window. Full-house upgrades generally take a few days, depending on the number of windows, the property layout, and the condition of the frames being replaced.
