My Patio Glass Door has Condensation—Should I Keep or Replace?

Patio door interiorPatio glass door condensation is like an annoying case of seasonal allergies, but for your home. Vastly different indoor and outdoor temperatures, such as what might occur during the hottest summer months and coldest winter months, is often the culprit behind moisture build-up on your glass installations.

Continual condensation may have you wondering if your patio glass door has a defect. However, it’s important to understand that glass can’t generate condensation itself, rather interior and exterior condensation results from drastically different temperatures inside and outside of the glass panes.

If it is warmer inside than outside, condensation may form on the inner glass layer. If it is warmer outside than inside, condensation may form on the outer glass layer. Luckily, there are several simple and quick fixes you can try to help reduce and prevent condensation.

To Keep or To Replace Your Patio Glass Door?

You want to avoid mold growth on your window coverings and a number of infrastructure problems such as:

  • Peeling paint

  • Rotting wood

  • Buckling floors

  • Deteriorating insulation, paneling, and window sills

So, should you keep or replace your patio glass door if it has interior condensation?

“Laboratory testing shows that modern double-paned windows with low-e glass and argon gas allow about 37% relative indoor humidity without condensation (at 70 F inside, 0 F outside). Old single-pane windows only allow about 12% relative indoor humidity.” -

If you’ve ever heard of the expression “If it ain’t broke, don’t fix it?” Similarly, unless there’s condensation between your double pane patio glass door or you are trying to maximize your energy savings by upgrading from single pane to double pane patio glass doors, you shouldn’t need to replace your doors.

There are several ways you can control, reduce and even prevent condensation from forming on your patio glass door. Here’s three tips to get you started:

1. Open your windows

This will help to even out the inside and outside temperatures and circulate the moisture produced from cooking, showering, ironing etc. in your home

2. Invest in a dehumidifier

You can shop for a dehumidifier, such as Damprid, on Amazon or at your local department store to help absorb moisture inside your home and reduce condensation on your patio glass door.

3. Balance your thermostat

Try to create a temperature inside your home that is comfortable but not drastically different from the outside temperature.
