Stop Leaks and Draughts Before They Damage Your Home
We know how frustrating it can be to deal with leaky or draughty windows. What might seem like a small issue can quickly lead to bigger problems—water damage, mould growth, and rising energy bills. This guide explains the most common causes of leaks and draughts, how to detect them, and the solutions that will restore comfort, efficiency, and value to your home.
Why Window Leaks and Draughts Matter
Leaks and draughts are far more than just minor annoyances. When cold air seeps in during winter or hot air infiltrates your home in summer, your heating and cooling systems are forced to work harder, driving up energy consumption and utility bills. Excess moisture from leaks can also cause serious damage to your property, leading to peeling paint, warped timber, and even mould growth that threatens both your home’s structure and your family’s health.
Beyond the immediate discomfort, these problems can increase your energy bills significantly—by as much as 10 to 20 percent in older homes. Addressing leaks and draughts early not only improves the comfort of your living spaces but also protects your home’s long-term value and ensures a healthier indoor environment.
Common Causes of Window Leaks and Draughts
Several factors can cause windows and doors to lose their seal and let in unwanted air or water:
- Damaged or worn seals: Over time, rubber seals and weather stripping can crack, shrink, or detach.
- Poor installation: If a window or door wasn’t installed correctly, gaps may appear between the frame and the wall.
- Frame damage: Warped timber or corroded aluminium frames create spaces for air and water to pass through.
- Glass problems: Cracked panes or broken glazing units allow direct leaks.
- Structural movement: Houses naturally settle, and even small shifts can compromise window alignment.
- Blocked drainage channels: Modern windows have weep holes to allow water to escape; if they’re blocked, water builds up and seeps inside.
How to Detect Leaks and Draughts
Not sure if your windows are the culprits? Here are some easy ways to check:
- Visual signs: Look for peeling paint, damp patches, mould, or staining around window frames.
- Condensation clues: Fogging or water between glass panes can signal failed seals.
- The smoke test: Hold a lit incense stick or candle near the edges of a closed window. If the smoke flickers, air is getting in.
- Listen and feel: On windy days, listen for whistling noises and feel for cold air entering.
- Thermal cameras: Professional inspections can use infrared imaging to show exactly where heat is escaping.
DIY Solutions vs Professional Repairs
You might be tempted to fix leaks and draughts yourself. While temporary measures can help, they often don’t solve the root cause.
| Aspect | DIY Solutions | Professional Repairs |
| Cost | Lower upfront cost with basic materials like sealant or weather stripping. | Higher initial investment, but long-term savings through durability and warranties. |
| Effectiveness | Often temporary; may not address underlying issues such as warped frames or structural gaps. | Comprehensive solutions that tackle root causes, ensuring lasting results. |
| Skill Required | Easy to attempt, but limited to simple fixes; mistakes can make the problem worse. | Performed by licensed experts with years of experience in window and glazing repairs. |
| Durability | Short-term relief; leaks and draughts often return within months. | Long-lasting performance with high-quality materials and professional installation. |
| Time & Effort | Requires homeowner time and effort; can be messy and inconsistent. | Quick, efficient service that saves you time and provides peace of mind. |
| Warranty | No guarantees—if it fails, you’ll need to redo the work. | Professional service is usually backed by a service guarantee and manufacturer’s warranties. |
Choosing a professional solution ensures the problem is fully resolved and covered by warranty, saving you from recurring costs.
