How do I keep my storm door from icing up?

Do you have a main door to the house and the storm door on the outside? It's possible warm air from the house is leaking past the main door and hittng the storm door causing condensation. You need to check the weatherstripping on the main door. May need to replace or install weatherstripping to prevent warm air from escaping towards the outside.

It seals very tight but in will recheck it with a smoke bomb. Thanks.

I just thought that's what they do in winter.

Hello Mag,

I fear you need to reglaze the door or replace the whole unit. The only temp. thing I could think of that will help with moisture build up and that is to place a Bowl of Salt just inside (It will draw the moisture) When full with water, empty water out and dry salt in the microwave and then place it back. repeat as and when. Otherwise buy dehumidifier packs and leave them about. Best wishes.

I have the same problem with my storm door. Most of the condensation is due to the fact that this is the door we use to take 2 dogs in and out. And the fact that northern Minnesota gets really really cold! This is a new storm door--my old one did not do this--and my inside door is also new with new weather stripping. I live with it in the winter but it drives me crazy! Since it does have 2 windows/screens that you can open and close I am considering adding a plexi glass "storm window"--there is a slot where it will fit--and perhaps that will help. I thought about sealing it with shrink wrap but the tape will not stick because of the cold and the moisture from the door window freezing and thawing.

Have you cleaned the glass with alcohol? Alcohol has a lower freezing point. You may also wish to wax the storm door frame, and check to be sure that the glass fits securely in the storm door. Is your glass a solid piece, or 2 panes (upper and lower, that slide over each other for winter use)?

We had to have a window company reglaze ours.

Try waxing to repel the water.

You could try using Shaving Foam, as they say that is good for stopping Mirrors from fogging up in Bathrooms, or maybe WD-40?

You need to drill holes at the top and bottom of the door. Drill four 3/16-inch-diameter holes, two about a half inch from the top of the door and two about a half inch from the bottom. This will allow air to circulate without reducing the effectiveness of the storm door.

Hi Mag: Maybe what works for mirrors will work for your door. Try spraying on a light coat of shaving cream and then wiping it off. Or, you can try using Rain-X, the product for car windows. Both should work :)

It sounds like condensation between your main door and the storm door. Try adding weatherstripping to the main door to stop the air leak.

A heated panel may be?

Hi Mag: What's happening is that if the sun is shining on the window when it's cold or humid out, it creates condensation. If your front door is open, then that wouldn't happen as the air wouldn't get trapped. You can put weather proofing around the door frame and maybe a sweep on the bottom of the door, but if the sun is shining on the area, it will ice up. You can wash the window with shaving cream, and that will help with the fogging.

Hi Mag, hope this helps you. Anti-frost coatings are specifically made for this and can be applied to the interior surface of your storm door to help prevent ice formation. These coatings work by reducing the surface tension of water, making it harder for frost to stick to the glass. To apply an anti-frost coating, do the following:

1. Clean the glass thoroughly with a glass cleaner and lint-free cloth.
2. Apply the anti-frost coating according to the manufacturer’s instructions, typically using a soft cloth or sponge.
3. Allow the coating to dry completely before closing the storm door.

To keep a storm door from icing up, seal air gaps with weatherstripping and caulk, lubricate the hinges and sweep with silicone spray, and reduce indoor humidity by using exhaust fans or a dehumidifier. You can also open the storm door's vent screen for a bit of ventilation or apply temporary insulation like window film.
