Surrey’s weather can take a real toll on the windows and doors that protect your home. Over time, changing weather patterns can affect how well they insulate, how they operate, and how they look.
If you have ever wondered why some windows start to mist, why doors begin to stick, or why draughts seem worse, the answer often lies in the weather. Understanding how the elements play a role can help you spot early signs of wear and know when it might be time to upgrade.
At Sheerwater Glass, we work on homes across Surrey and surrounding areas every day, so here is a clear homeowner-friendly guide to how local weather affects your windows and doors.
Temperature swings and frame movement
One of the biggest factors is temperature. Surrey experiences warm summers and chilly winters, and these shifts can cause materials like uPVC, aluminium, and timber to expand and contract.
uPVC expands slightly in the heat, which is why a door might feel a little harder to open on a hot day. As temperatures cool, it settles back into place. Aluminium handles temperature changes much better due to its stability, while timber reacts the most because it is a natural material that absorbs and releases moisture.
Over many years, constant movement can affect how well windows and doors close. If the frame no longer sits perfectly square, small gaps can appear and draughts become more noticeable. You might also find hinges and locking points becoming misaligned. Regular servicing and occasional adjustments help, but very old frames eventually reach a point where replacement gives the best long term result.
Heavy rainfall and moisture build up
Surrey sees its fair share of rain. From heavy autumn showers to long, damp spells in winter, moisture is one of the most common causes of window and door issues.
Older timber frames can absorb water, which leads to swelling, paint flaking, soft spots, or rot. If the rot sits deep in the frame, it affects both appearance and performance. Modern timber frames are treated to resist moisture far better, but older ones often struggle after years of exposure.
uPVC and aluminium do not absorb water, but seals and gaskets can deteriorate over time. When this happens, water may find its way into the frame or trickle onto internal sills. A quick inspection usually reveals cracked seals or perished rubber. Replacing these parts helps restore weather resistance, but if the frames themselves are worn out, it can be more practical to upgrade.
Prolonged damp weather can also encourage condensation inside the home. If you see moisture forming between panes of glass, it means the sealed unit has failed. The window no longer insulates effectively and should be replaced.
Wind and pressure on older frames
Blustery days are becoming more common, with stronger winds, especially during winter storms. Strong wind puts pressure on older window and door frames. If those frames have weakened over time or lack modern reinforcement, you might notice rattling, draughts, or difficulty closing them securely.
Modern uPVC and aluminium systems include internal strengthening and high quality locking points to withstand these conditions. They stay rigid, keep the weather out, and maintain a tight seal. Upgrading to newer frames often solves long standing draught issues for this reason.
Seasonal humidity and sticking doors
Humidity plays a subtle but important part in door performance. Wooden doors in particular expand when moisture in the air increases, which often causes sticking or rubbing during damp spells. Once the weather dries out, the door usually relaxes again. If the swelling becomes excessive, it may mean the door has reached the end of its life or simply needs a more stable material.
Composite doors, which combine a strong core with a weather resistant outer surface, are designed to avoid this issue entirely. They maintain their shape in all seasons and offer reliable insulation and security throughout the year.
Sunlight, fading, and heat management
On bright days, sunlight is something many homeowners want to maximise. The downside is that UV rays can affect older glazing and finishes. Faded paintwork, discoloured uPVC, and worn timber coatings are common signs of long term sun exposure.
Modern glazing is built to handle this far better. Low iron glass, coatings that reduce solar gain, and improved frame finishes help retain clarity and colour. This keeps your windows looking fresher for longer and improves comfort inside the home by controlling heat levels.
Frost, cold spells, and heat loss
Every winter brings a run of frosty mornings, and it is during these cold spells that older windows show their limitations. Single glazing, poorly insulated frames, and old seals all allow heat to escape. You may notice cold patches in certain rooms, rising energy bills, and iciness around the edges of the frame.
Modern double and triple glazing works much harder for your home. Gas filled units, warm edge spacers, and advanced coatings keep heat inside where it belongs. Homeowners usually feel the difference immediately after upgrading, especially in older Surrey properties.
What you can do to protect your home
A few simple checks go a long way. Look for misted units, cracks in seals, stiff handles, or visible gaps around frames. These are early signs that weather has taken its toll. Regular cleaning and gentle lubrication of hinges also help keep things running smoothly.
If the issues keep returning or your windows and doors are over 20 years old, replacement is usually the best way to improve energy efficiency, comfort, and security. New frames are designed for the changing climate and built to handle the weather patterns we see today.
