3 Signs It’s Time to Replace Your Sliding Patio Doors

So how do you know whether you should repair or replace your door? In today’s post, Renewal by Andersen® of San Antonio shares some red flags that indicate it’s time for a new door installation:

  1. Excessive Air or Water Leakage

If there are gaps around your doors, this is bad news on many levels. First, it causes indoor air to leak out of your home, which means your HVAC system has to compensate, leading to inflated energy costs. Second, breaches in your door can cause water to infiltrate the inside of your home, damaging your valuables. Third, insects can exploit such holes, leading to an infestation in your home.

To determine if you’re due for a replacement, consult with proven experts in patio and entry doors like Renewal by Andersen® of San Antonio.

  1. Difficult Operation

Consider getting new sliding doors if your existing ones need more than one person to operate. When the door panels stick, it usually means they are misaligned from their tracks. Continuing to use them may only compound the issue.

In addition to inconvenience, jerky doors can make your home less safe. They need to open and close smoothly to provide an easy means of egress and ingress in case of emergency.

  1. Poor Energy Efficiency

Buying ENERGY STAR®–certified patio doors can reinforce your house’s thermal enclosure system, regulating your home’s indoor climate. Look for gliding units with over 50% glass with ratings of a 0.30 U-factor or less and a 0.25 SHGC or less. This combination of energy ratings meets the requirements of the Southern Climate Zone, where Bexar, Medina and Comal counties are located. If your current sliding doors lack key design elements like multiple panes, they can’t truly enhance thermal insulation and prevent extreme solar heat gain.
