Summer in Surrey & the Case for Draught Proofing

Every year, Surrey experiences hotter summers with sudden heatwaves and increasingly unpredictable weather. Homeowners who used to worry mostly about cold draughts now find themselves struggling with sweltering rooms, relentless sunlight, and higher energy bills just to stay comfortable. Many families in Guildford, Woking, and the surrounding areas notice that by midday, upstairs bedrooms and south-facing lounges become stifling, while any attempt at cooling seems to vanish in a matter of hours.

If this sounds familiar, you’re not alone. A growing number of local residents are looking for effective ways to keep cool and reduce costs without running fans or air conditioning non-stop. The answer? Window draught proofing. It might sound like a solution for winter, but it’s actually a summer game-changer too.

Why Draught Proofing Works Year-Round

All-Season Benefits

Most people think of draught proofing as a cold-weather fix, but in reality, draughts work both ways. They let precious warm air escape in winter, and just as easily let cool air leak out in summer. So sealing up those gaps can make the difference between a bearable house and one that feels like a greenhouse.

Local Perspective

In Surrey, traditional houses with sash or casement windows are especially vulnerable to leaks, but even modern uPVC frames can develop air gaps over time. Also, while new-builds are supposed to meet the latest efficiency standards, real-world surveys show that even recently installed windows can have draughts problems. It’s no wonder many local homeowners treat draught proofing as a necessary upgrade. 

The Science of Draughts: What Actually Happens

Airflow and Pressure Differences

Draughts are a physical process driven by pressure differences between indoors and outdoors. In summer, the “stack effect” can pull warm air up through a house, creating negative pressure that literally sucks in hot air from outside, and often through the smallest window gaps. Thermal imaging shows just how much air can leak even from “closed” windows.

Where Draughts Hide

You may  be surprised by the number of places air can sneak through:

• Around the window frame and sash
  
• Through loose or shrunken gaskets (especially on uPVC)
  
• Via trickle vents left open (or fitted poorly)
  
• At meeting rails and beads
  
• Around handles, locks, and hinges
  
• Through glazing bars, mastic, or perished sealant

Understanding where air escapes is the first step in choosing the right draught proofing solution for your home.

How Draught Proofing Windows Makes Summer Bearable

Locking in the Cool

Anyone who’s invested in a good fan, air conditioning unit, or just loves throwing open windows on a summer evening knows how precious a cool breeze can be, but what happens next is key: if your windows and doors aren’t properly sealed, all that comfort can disappear in a very short space of time.

Research and real-life stories show that well-sealed windows can keep a room up to 4°C cooler at the hottest part of the day, simply by preventing overnight and early-morning cool air from leaking out.

Reducing Bills

With every passing year, Surrey’s energy prices seem to rise and so does the temptation to rely on expensive cooling devices. According to the Energy Saving Trust, draught proofing windows and doors is one of the simplest ways to reduce unnecessary energy use in both summer and winter.

For a family using air conditioning (portable or fixed), blocking draughts can reduce run times considerably, saving both money and the environment. 

Allergy, Dust, and Pollen Reduction

Summer in Surrey means hayfever season for thousands of residents. Unsealed windows allow pollen, dust, and pollution to drift inside even when you think everything’s shut tight. Draught proofing windows may keep the temperature down but it also helps allergy sufferers breathe easier.

UPVC Window Draught Proofing: Not Just for Old Houses

The Myth of Maintenance-Free uPVC

uPVC windows are often sold as “fit and forget,” but the reality is that gaskets and seals have a lifespan. Sunlight, fluctuating temperatures, and general wear cause gaskets to shrink, harden, or lose their elasticity. Even the tiniest gap lets in draughts, insects, and moisture, which is something many Guildford and Farnham homeowners discover after just a few years.

To give you some idea, the average lifespan of uPVC window gaskets is 8–12 years. Beyond that, seals can start to fail and cause draughts that are especially noticeable on windy or very hot days.

Technical Deep Dive

There are several ways you can start draught proofing uPVC windows:

• Bubble gaskets: Common in new windows
  
• Q-Lon memory foam gaskets: Excellent memory recovery, plus outstanding thermal and acoustic performance
  
• E/P (flipper) seals: Flexible, great for moving sashes
  
• Brush strips: Good for sliding or tilt-and-turn windows
  
• Compression seals: A tight fit for older frames or those with slight warping

County Secure, can identify the correct material for each frame and guarantee a snug, long-lasting fit.

What Surrey Homeowners Experience

Professional window draught proofing delivers immediate and measurable improvements The most common feedback from our Surrey clients has been how much more comfortable their homes feel during hot spells, bedrooms stay cooler for sleep, and living areas don’t become stifling by midday. Energy bills also typically show a reduction within the first month, particularly for homes using air conditioning or fans regularly during summer heat waves.

Professional vs. DIY Draught Proofing: The Real Difference

DIY Kits & Quick Fixes

It might be tempting to pick up a foam tape kit from the DIY store and fix the various draught proofing issues yourself, but the problem lies in the fact that most DIY products wear out within a couple of years or less, especially on high-use windows, and often leave gaps that you can’t see but can definitely feel.

DIY is ideal for:

• Renters needing temporary improvement
  
• Older timber windows where full restoration isn’t possible yet
  
• Quick, low-cost comfort boost

So in summary, DIY kits may be a short term fix but professional draught proofing offers far better value over the long term.

Professional Draught Proofing

At County Secure, our window draught proofing service starts with a site survey. We make a point to check every window and door so we can identify the leaks you may be aware of along with the leaks you may not know exist. Once the survey is finished we’ll recommend the right solution for each type.

To give you some idea, our window draught proofing service may include::

• Removal of old, perished seals
  
• Cleaning and preparation of all surfaces
  
• Fitting of new, UV-resistant gaskets or brush seals
  
• Testing for air-tightness and function

Balancing Window Draught Proofing and Ventilation: Getting It Right

Why Airflow Matters Even When Sealed

A common concern is that sealing up every gap will make a house feel stuffy, damp, or unhealthy. The truth is, draught proofing blocks uncontrolled air movement (draughts), while maintaining intentional, healthy ventilation.

Modern uPVC windows feature trickle vents which are discreet slots at the top of the frame, and designed to let in just enough fresh air without wasting energy. It’s important to keep these clear and use them wisely, especially in summer when pollen or pollution can be an issue.

Smart Ventilation for the Modern Home

For best results, pair draught proofing with:

• Scheduled window openings: Ventilate at night or early morning, then seal up during the heat of the day
  
• Tilt-and-turn windows: These allow variable opening, so you can fine-tune air flow without sacrificing comfort.
  
• Passive air inlets: A great choice for allergy sufferers, offering filtered fresh air

County Secure always assesses your ventilation needs including window ventilation as part of every draught proofing project.

Security Benefits: Safer Home, Safer Summer

How Draught Proofing Supports Home Security

Loose, rattling windows are both an energy problem and a security risk. Draught proofing windows and doors naturally tightens all opening sections, making them much harder to force open from the outside. If you’re interested in having additional security, we provide a range of security product upgrades for both windows and doors.

As Secured By Design notes, visible security improvements can also deter opportunist burglars giving you added peace of mind, especially when you’re away for summer holidays.

Maintenance & Lifespan: Keeping Draught Proofing Effective

How to Inspect and Maintain Your Draught Proofing

To get the most from your investment:

• Inspect seals and gaskets annually for shrinkage, cracking, or detachment
  
• Clean with mild soap and water; avoid harsh chemicals or pressure washers
  
• Keep trickle vents free of dust and cobwebs

County Secure’s Aftercare Promise

As part of our commitment to local homeowners, we offer free follow-up checks within the guarantee period, and ongoing advice on window and door care for support.

Most professional seals will last at least 5–10 years but if you notice cold or hot spots returning, contact County Secure for an inspection.

Environmental Impact & Sustainability

Draught Proofing and the Planet

Every kilowatt-hour of energy saved through draught proofing windows and doors means fewer greenhouse gas emissions and a smaller carbon footprint. Choosing to repair and upgrade existing windows, rather than replace them entirely, is also a more sustainable choice that avoids waste and the environmental cost of new materials.
