Increased Property Value
Homes with modern double glazing tend to fetch higher prices when sold because:
- Buyers appreciate the long-term savings on energy bills.
- New homeowners won’t need to replace old windows, making the property more move-in ready.
Environmental Impact
Double glazing isn’t just a financial investment; it’s an eco-friendly option. By improving insulation, you’re using less energy, which contributes to:
- Lower CO2 emissions
- Sustainable living practices, which many homeowners are prioritizing.
Choosing the Right Double Glazing
This section guides you through the decision-making process when choosing a double glazing solution and provider. It will help you make an informed decision based on material types, styles, and installer qualifications.
Types of Double Glazing: Materials and Styles
When selecting double glazing near me, it’s important to choose the right type of material and style that suits your needs. Here’s a comparison to help you understand the benefits and costs of each option:

Frequently Asked Questions (FAQ)
When considering double glazing, it’s normal to have questions about the process, costs, and benefits. Below, we answer some of the most common questions to help you make an informed decision.
1. How long does double glazing last?
Most double glazing units are designed to last between 20 and 35 years, depending on the materials used, the quality of the installation, and how well they’re maintained. UPVC and aluminum frames are particularly durable, requiring minimal upkeep, while timber frames may need more frequent maintenance to extend their lifespan.
2. Can I repair misted double glazing, or do I need to replace it?
In some cases, misted double glazing can be repaired by resealing the unit or inserting a dehumidifier. However, if the seal is severely damaged, it’s often more effective to replace the glass unit. Repairing the seal typically costs between £50 and £150, while replacing the unit can cost between £100 and £300 per window.
3. How much does double glazing cost?
The cost of double glazing depends on several factors, such as the material, window size, and type. On average:
- UPVC windows cost between £250 and £400 per window.
- Aluminum windows range from £500 to £700.
- Timber windows can cost between £900 and £1,500 per window.
Larger homes or specialized glazing (such as soundproof or frosted glass) will increase the overall cost. Be sure to get multiple quotes for an accurate estimate.
4. Can I install double glazing in a listed building or conservation area?
Yes, but you may face restrictions. Listed buildings and conservation areas often have rules about altering the appearance of windows. In such cases, secondary glazing—which involves adding an additional pane inside your existing windows—can be a suitable solution. This provides the benefits of double glazing without altering the external look of the building. Always consult with your local planning authority before making changes.
5. What are the benefits of triple glazing over double glazing?
Triple glazing offers enhanced insulation compared to double glazing, making it especially effective in very cold climates. The extra pane of glass provides:
- Better thermal efficiency: Reduced heat loss, keeping homes warmer.
- Improved noise reduction: Triple glazing is excellent for blocking out external noise.
However, it is more expensive than double glazing, and for most homes in the UK, high-quality double glazing is sufficient for energy savings and noise reduction. Triple glazing typically costs about 30-50% more than double glazing.
6. How long does it take to install double glazing?
The installation process usually takes between 1 and 2 days for an average-sized home. Larger or more complex installations, such as those requiring scaffolding or specialized glazing, may take longer. Most installers will provide an estimated timeframe based on the number of windows and the complexity of the installation.
7. Will double glazing improve my property’s value?
Yes, installing double glazing can increase the value of your property, particularly if your current windows are outdated or inefficient. Potential buyers are often attracted to homes with modern, energy-efficient windows, as they reduce energy bills and improve comfort. According to estate agents, homes with modern double glazing can see a 5-10% increase in property value.
8. Does double glazing reduce condensation?
Double glazing helps to reduce condensation by creating an insulating barrier between the warm air inside your home and the cold air outside. However, if condensation forms between the panes of glass, it’s a sign that the seal is broken and the unit needs repair or replacement. To prevent internal condensation, ensure your home has adequate ventilation, especially in areas with high humidity like kitchens and bathrooms.
9. Is double glazing environmentally friendly?
Yes, double glazing is considered environmentally friendly because it helps to reduce energy consumption by improving insulation. By retaining heat in winter and keeping homes cool in summer, double glazing reduces the need for heating and air conditioning, leading to lower carbon emissions. Additionally, many double glazing materials, such as UPVC, are recyclable.
10. Can I get a warranty for my double glazing?
Most reputable double glazing companies offer a 10 to 15-year warranty on their products, covering issues like defective materials, seal failure, and installation errors. Be sure to read the warranty carefully to understand what is covered and for how long. Some companies also offer extended warranties or service plans for added peace of mind.
11. What should I look for in a double glazing installer?
When choosing an installer, prioritize the following:
- Certifications: Look for companies accredited by FENSA, TrustMark, or Checkatrade.
- Customer Reviews: Check online reviews to ensure previous customers were satisfied with the quality of the installation.
- Warranties: A solid warranty on both materials and labor is crucial.
- Free Quotes: A reputable company should offer a free, no-obligation quote and a clear breakdown of costs.
Also, consider asking for recommendations from friends or family who have had positive experiences with local installers.
