Hot One Week, Pouring the Next – Can Your Windows Keep Up?

Posted on 3rd June 2026 at 16:56
Last week we were hunting for fans and ice lollies. This week? Back to waterproofs and wondering where summer went. 
 
Typical Britain. 
 
But while we're all used to the weather's mood swings, your windows might not be coping quite so well. 
Sudden changes from hot sunshine to cooler, wetter conditions can expose problems that have been hiding in plain sight for years. 
 
Did Your Home Turn Into a Greenhouse? 
 
During the recent warm spell, many homeowners noticed certain rooms becoming uncomfortably hot. 
If you found yourself closing blinds, opening every window in sight, or avoiding the conservatory altogether, your glazing may not be performing as efficiently as it should. 
Modern energy-efficient windows help regulate indoor temperatures, keeping homes more comfortable whatever the forecast decides to do. 
 
Now The Rain's Back... 
 
As temperatures drop and the clouds roll in, different issues start to appear: 
 
Cold draughts around windows 
Condensation on glass 
Rooms cooling down quickly 
Higher heating bills 
Windows that rattle in windy weather 
 
These are often signs that ageing windows are no longer providing the insulation your home needs. 
 
A Quick Window Health Check 
 
Ask yourself: 
 
✓ Do some rooms feel colder than others? 
✓ Are you noticing more condensation? 
✓ Can you feel draughts near windows? 
✓ Have your energy bills crept up recently? 
 
If you answered yes to any of the above, it could be time to consider an upgrade.

Choosing the right type of windows

Posted on 3rd February 2026 at 14:08
Replacing your windows is one of the most effective ways to improve comfort, energy efficiency, and the overall look of your home. But with different materials available, choosing the right type of windows is key to getting the best long-term value. 
 
Below is a simple guide to the most popular replacement window options for UK homeowners. 
 
PVCu Windows – The Popular, Cost-Effective Choice 
 
PVCu windows remain the most common choice for window replacement in the UK. They’re low maintenance, affordable, and offer excellent thermal performance. Modern uPVC designs suit both traditional and contemporary homes, making them ideal for homeowners looking to reduce heating bills without compromising on style. 
 
Best for: Energy efficiency, value for money, minimal upkeep. 
 
Aluminium Windows – Sleek and Modern 
 
If you prefer a contemporary look, aluminium windows are an excellent option. Their slim frames allow more natural light into your home while still providing strength and durability. Aluminium is also highly resistant to warping and corrosion, making it a long-lasting solution. 
 
Best for: Modern homes, large window openings, clean architectural lines. 
 
Timber Windows – Classic and Characterful 
 
For period properties or homeowners wanting a traditional finish, timber windows offer natural beauty and character. When properly manufactured and installed, modern timber frames can still deliver strong insulation and longevity. 
 
Best for: Period homes, listed-style properties, classic aesthetics. 
 
Why the Right Installer Matters 
 
No matter which window material you choose, professional installation is crucial. A reputable local window installer will guide you through the options, explain costs clearly, and help you choose windows that suit your home, budget, and style — without pressure or confusing jargon. 
 
NatCon Windows specialises in PVCu, aluminium, and timber window installation, helping homeowners make confident, informed decisions from first consultation to final fit.

1970s & 1980s Homes: Are Your Windows Letting You Down?

Posted on 26th January 2026 at 12:46
Homes built in the 1970s and 1980s make up a huge proportion of properties across Sussex, Surrey and Kent — and many of them still have their original windows or early double glazing. 
 
While these homes aren’t considered period properties, their windows are often now 40–50 years old, meaning performance can fall well short of modern standards. 
 
Why Older Windows Struggle in 70s & 80s Homes 
 
Early double glazing was a big step forward at the time, but technology has moved on significantly. Over the years, common issues include: 
 
Failed window seals, allowing heat to escape 
Condensation between panes, caused by broken units 
Noticeable draughts, even when windows are closed 
Increased outside noise 
Higher heating bills, especially during winter 
 
If you’re experiencing one or more of these issues, your windows may no longer be doing their job effectively. 
 
How Modern uPVC Windows Improve Comfort 
 
Modern uPVC double glazed windows are far more advanced than those installed decades ago. Today’s systems typically include: 
 
Low-E glass to reflect heat back into your home 
Improved spacer bars to reduce cold bridging 
Advanced sealing systems to prevent draughts and leaks 
Energy-efficient frames that won’t warp or rot 
 
For homeowners in towns such as East Grinstead, Crawley, Horsham, Tunbridge Wells and surrounding areas, upgrading windows often leads to warmer rooms, quieter interiors and better energy efficiency almost immediately. 
 
Is It Time to Replace Your Windows? 
 
If your home still has its original 1970s or 1980s windows, replacement can be one of the most effective home improvements you make. Not only does it improve comfort and reduce heat loss, but it can also refresh the appearance of your property and add long-term value.
