Draughty Window

A draughty window is a common issue where cold air seeps into your home, often described as a window not sealing properly or cold air coming through the window. This can make rooms feel chilly, increase heating bills, and sometimes lead to a rattling window during windy weather. At Window Repairs Sutton, we specialise in diagnosing and fixing these problems for uPVC windows in Sutton.

What This Usually Means

A draughty window typically signals that the seal between the window sash and frame has failed, allowing unwanted air exchange. You might notice a constant chill near the window, even with heating on, or feel a breeze on your hand when testing. In severe cases, it could accompany a rattling window, pointing to movement in the frame or hinges.

This symptom often worsens in winter, making your home less energy-efficient. It’s not just uncomfortable—drafts can contribute to condensation and mould over time. Early attention prevents bigger issues like frame warping.

Common Causes

Several factors cause a draughty window in uPVC systems, which we repair regularly.

• Worn or compressed weatherseals: Rubber seals degrade over 10-15 years from weather exposure and daily use, cracking or flattening.
• Frame misalignment: Settling buildings or worn hinges cause the window to sit off-kilter, creating gaps.
• Loose or faulty hinges: Friction stays or hinges that have seized allow the sash to shift, leading to poor closure.
• Damaged locks or handles: These prevent proper compression against seals, exacerbating drafts.

We focus on uPVC window repairs and don’t handle sash windows, sliding windows, tilt and turn, inward opening, or wooden frames. With 10+ years’ experience and public liability insurance, our DBS-checked technicians address these root causes efficiently.

Safe Checks Before Booking

Before calling for window repair, perform these straightforward, safe checks to confirm a draughty window.

• Hold your hand near the closed window frame on a breezy day—feel for air movement, especially at edges or corners.
• Use lit incense or a damp tissue; watch for smoke deflection or tissue movement indicating cold air coming through the window.
• Visually inspect seals for cracks, gaps, or brittleness; gently press the sash to check for play.

Avoid forcing adjustments yourself, as this risks further damage to hinges or locks. Note any rattling window, which suggests mechanical issues. These steps help pinpoint if it’s window adjustment or seals needed.

If checks confirm the problem, explore our symptoms page for related issues like misted units.

Likely Fixes

Most draughty window problems stem from seals or alignment, both fixable without full replacement. Here’s a decision guide to the right solution:

• Seals feel perished or flat? Replace with new draught excluders and weatherseals—a quick, cost-effective uPVC window repair.
• Window doesn’t close squarely or rattles? Book window draught proofing and alignment, including toe and heel adjustment for proper sealing.
• Hinges or stays sticking? Opt for hinge replacement alongside alignment to stop movement and drafts.
• Handle or lock not engaging fully? Handle or lock repairs ensure compression, eliminating gaps.

Our services cover uPVC window repairs, draught proofing, adjustment, and hinge replacements. Local to Sutton and fully insured, we prioritise practical fixes.

FAQs

What causes cold air coming through a window even when closed?

Cold air coming through a window usually results from worn weatherseals or misalignment, preventing a tight seal. Less commonly, it’s due to hinge wear allowing sash movement.

Can I fix a draughty window myself?

DIY might involve cleaning seals, but replacement or adjustment requires tools and expertise to avoid damage. Professional uPVC window repair is safer for lasting results.

How much does window draught proofing cost?

Costs vary by window size and issue—seals are cheaper than full alignment. Contact us for a no-obligation quote tailored to your Sutton property.

Does a rattling window always mean drafts?

Often yes, as loose components create gaps, but it could be isolated to hinges. Our checks diagnose both.

Do you repair draughty wooden or sash windows?

No, we exclude sash windows, sliding, tilt and turn, inward opening, or wooden window repairs. We specialise in uPVC systems.

How quickly can you fix a window not sealing properly?

We aim to respond promptly as a local Sutton service, but no fixed timelines—contact us to discuss.
