During winter, your windows will often be exposed to cold air on the outside while the water vapor from the indoor air solidifies and forms into liquid from the inside. That liquid then freezes into ice crystals and turns into frost. As the frost melts, the moisture can damage the surrounding material, creating cracks and discoloration from the varnish and paint. Mold can also grow if this isn’t handled properly, and you may end up with having to pay for a window replacement.

If left unchecked, frost can be damaging to your windows. Our team at Renewal by Andersen® of Seattle shares their insight.
Why You Should Prevent Frost From Forming
When you see frost and ice buildup from your windows, it can lead to several problems at your home, such as:
- Window Damage – The constant shrinking and swelling of your windows can crack your glass and water leak problems
- Heat Loss – This happens when the inside pane of the glass becomes frozen. This compromises its thermal protection, making you lose heat from your home.
- Mold and Health Issues – Mold can grow from the constant freezing and melting of the moisture, which can lead to lung, sinus, and other health problems at home.
How You Can Prevent Frost and Ice Buildup
One of the best ways to keep frost and ice from forming on your home’s casement and bay windows is to have them weatherized. This means hiring a contractor to caulk all the gaps in your window seals and ensure that they’re installed properly. Another way is to keep your home sufficiently warm as well as using a dehumidifier, which keeps the air dry and prevents moisture from turning into frost.
If your windows need replacing, make sure you get them double- or even triple-paned from a reputable window manufacturer. A good window company also takes care of the installation, so you can be sure that your new windows will perform as well as they’re expected to.
