4 Common Replacement Window Problems

Home renovations are a nice way to add a refreshing touch to your house. Even your newest additions will eventually have issues and need repairs.

4 Common Replacement Window Problems

Fortunately, it’s not something that a professional windows company like Renewal by Andersen® of St. Louis can’t fix. Here are the four most common replacement window problems to give you an idea of what you may be dealing with in the future.

1. Condensation

If you ever notice your windows becoming foggy, you may be dealing with condensation. If this happens to your window, it means that the seals in between the glass panes have deteriorated. Ice formation during extremely cold weather is also a possibility. This can be costly as this may force you to turn up your heating system, causing a hike in your electricity bill.

Having quality replacement windows installed is the solution. Along with fresh seals, make sure their warranties are valid as well.

2. Air Infiltration

Also known as air leakage, this problem arises when there are unsealed joints in a structure. When it comes to windows, this will eventually lead to unwanted cold air seeping into your home. As a result, this can also cause a significant impact on your electricity bill as you will need to turn up the heating to keep you and your family warm. This is nothing a thorough sealing can’t fix.

3. Seal Failure

Seal failure is often the cause of condensation and air infiltration of defective windows and doors. Whether because of a faulty installation process or the seal itself is not suited to your environment’s climate, seal failure is still something that you need to keep an eye out for to maintain energy-efficient windows. If you notice the beginnings of seal failure, get an expert to assist you.

4. Rot

Homeowners often opt for wood frames because of aesthetics. While pleasing to the eye, there’s also a possibility for them to decay despite excellent performance in the beginning. Prolonged moisture contact may be the cause. Once they start to decay, this may be a signal to have them replaced.

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
