As the colder months approach, your home’s glazed doors, whether bi-folds, sliding doors, or patio systems, become more than just an elegant feature. They act as an important barrier between your home and the elements, helping to retain warmth and prevent unwanted draughts.

At YES Glazing Solutions, we’ve spent over 25 years installing and maintaining high-performance glazing across the UK, and we know that a little preparation before winter can make all the difference.

In this guide, we’ll take you through the best ways to prepare your glass doors for the colder weather, ensuring they continue to perform efficiently, look their best, and last for years to come.

Winter weather often reveals small issues that can go unnoticed during warmer months. Dirt and debris can collect in tracks, preventing doors from gliding smoothly. Seals can wear down over time, allowing cold air and moisture to seep through. Mechanisms can stiffen or become misaligned, making operation difficult, and condensation can build up if ventilation isn’t managed properly.

By taking some time to care for your bi-fold and sliding doors before temperatures drop, you can prevent costly repairs, extend the life of your system, and maintain energy efficiency throughout winter.

Start by giving your doors a thorough clean. Use a soft, dry cloth to remove dust from the glass and frame surfaces, beginning inside and then working outward to avoid spreading dirt indoors. For the glass itself, a mild window cleaner or a simple mix of water and white vinegar works well. Spray the cleaner onto a microfibre cloth instead of directly onto the glass to prevent overspray, and then polish it dry for a streak-free finish.

Next, focus on the tracks, hinges, and rollers. These components often collect dirt, leaves, and grit, which can restrict movement. A vacuum with a narrow nozzle or a small cleaning brush can easily remove any debris. If your doors feel stiff, never force them, instead, check that the track is completely clear.

Once the visible dirt is gone, clean the frames and gaskets with warm, soapy water and a soft cloth. Avoid using harsh chemicals or abrasive pads, as these can damage the finish. Wiping down the seals and gaskets will also help you spot any cracks or areas of wear that might need attention.

Lubrication is another crucial step. Apply a silicone-based lubricant to the hinges, rollers, and lock mechanisms to ensure smooth operation. Make sure to clean off any old grease first so that the new lubricant can work effectively.

After cleaning and lubricating, check the alignment of your doors. They should open and close smoothly and sit evenly within the frame. If they don’t, a small adjustment to the rollers or hinges can often fix the issue. While you’re inspecting, take a close look at the seals around the doors. If you notice any cracks or gaps, it’s best to replace them before the colder weather sets in, as they play a vital role in keeping out draughts and moisture.

Homes are naturally more humid in the colder months, especially when windows are kept shut. To reduce condensation, use trickle vents if your system has them, or briefly open your windows or doors each day to allow moisture to escape. Modern thermally-broken frames and energy-efficient glass can help, but proper ventilation is still essential for keeping your glazing clear and performing well.

Finally, know when to call in the professionals. If your doors have serious alignment issues, cracked glass, or persistent operational problems even after cleaning and lubrication, it’s best to contact YES Glazing Solutions.
