As temperatures begin to drop, condensation makes a return to our homes.
You may notice it first thing in the morning: a misting across the glass. Moisture gathering on colder surfaces.
Condensation forms when warm, moisture-filled air inside the home meets a colder surface. Cooking, showering, drying clothes, breathing, all add moisture to the air. The problem often becomes more noticeable once windows and doors are closed and the heating goes back on.
A small amount of condensation on the inside of the glass does not mean there is anything wrong with your front door. However, it is worth keeping an eye on where the moisture appears and if it keeps returning.
Here are a few simple things to check:
- Wipe away condensation rather than allowing water to sit.
- Use extractor fans when cooking or showering.
- Open windows briefly each day to allow moist air to escape, particularly in bedrooms, kitchens and bathrooms.
- Avoid blocking air vents or trickle vents.
- Leave a little space between furniture and external walls so air can circulate.
- Check that door seals remain intact and that the door continues to close smoothly and evenly against the frame.
It is also important to identify exactly where the moisture is forming.
Condensation on the room-facing surface of the glass is usually linked to indoor humidity and the temperature of that surface.
Moisture trapped between the panes of a glazed unit could indicate that the sealed unit requires professional inspection.
Water gathering around the threshold during rain may be water ingress rather than condensation. If this happens, take photographs before wiping it away and contact the company that installed the door.
A well-fitted, thermally efficient front door can help reduce draughts and cold spots, but even the best-performing door cannot remove excess moisture from the air inside your home.
So, as condensation season approaches, keep an eye on your entrance. A few small changes to ventilation and everyday habits may be all that is needed to keep your door area dry, comfortable and ready for winter.
