When you’ve invested in high-quality double glazing for your home, it’s only natural to want to keep it in top condition for years to come. While our expertly crafted installations are designed to stand the test of time, a little routine care can go a long way. Whether you’re in the heart of Sheffield or the surrounding areas, these double glazing maintenance tips will help you protect your investment, keep your home energy-efficient, and ensure everything continues to look and perform as it should.
Understanding the benefits of double glazing
Double glazing offers multiple benefits beyond just enhancing your home’s appearance. One of the most notable advantages is improved energy efficiency—A-rated windows can reduce heating bills by up to 20%, according to the Energy Saving Trust. By preventing drafts and retaining heat, quality double glazing plays a vital role in making homes warmer and more cost-effective to run.
In addition to thermal performance, double glazing contributes to a quieter living environment by reducing external noise by up to 60%, making it ideal for busy neighbourhoods or roadside properties. These energy-saving and sound-insulating features not only bring comfort but also enhance your home’s value, giving it an edge should you ever decide to sell. Quality home improvements like these help maximise both kerb appeal and market desirability.
Regular cleaning and upkeep
Keeping your double glazing clean isn’t just about maintaining appearances—proper cleaning is essential for long-term performance. Start by using a mild soap solution and a soft cloth when cleaning the glass. Harsh chemicals or abrasive tools can scratch the surface or compromise the glazing layers.
Don’t forget the frames and sills, which are often exposed to the elements. Giving them a thorough clean at least twice a year will help prevent dirt and grime build-up. Periodically inspect the seals and gaskets too—these components help keep your home weatherproof and energy-efficient. If you spot any signs of wear or damage, it may be time for a replacement to prevent future issues like draughts or leaks.

Checking for condensation issues
Condensation can be more than just an annoying side effect of temperature changes—it may indicate problems with your glazing. If you see moisture inside your double glazing panes, it’s a likely sign that the seal has failed, allowing air and moisture to enter the unit.
Home humidity levels above 60% often lead to these kinds of issues—so monitoring with a hygrometer is always a smart move. To reduce the likelihood of condensation, ensure your home has proper ventilation and consider using a dehumidifier in certain rooms. Taking control of moisture in the air not only protects your glazing but also reduces the chances of damp or mould forming in the home.
Maintaining window and door locks
Your windows and doors aren’t just visual features—they’re essential to your home’s safety. That’s why lock and hinge maintenance is such an important aspect of double glazing care. Each year, lubricate all moving parts using a silicone-based lubricant to keep them operating smoothly.
During your inspections, be vigilant about signs of rust, wear, or loosening. These should be addressed quickly, as compromised hardware can lower security and affect the alignment of the entire frame. Simple checks and maintenance can prolong the lifespan of these vital components and give you peace of mind when it comes to your home’s safety.

Even with the most diligent DIY efforts, professional servicing is key to safeguarding your double glazing over the long term. We recommend scheduling an inspection every 5 to 10 years to identify any hidden issues and ensure optimal performance.
