3 Mistakes to Avoid When Replacing Your Windows

Most windows are built to last. In fact, the average window can be expected to last roughly 10 to 20 years before it starts to deteriorate. Be that as it may, no matter how durable your windows are, they will eventually need to be replaced. If the seals are beginning to weaken or if you notice that your utility bills have suddenly skyrocketed without any drastic changes in energy consumption, then you definitely should consider having them replaced. If this is the case for you, here are three things that you should avoid when shopping around for replacement windows.

3 Mistakes to Avoid When Replacing Your Windows

1. Making Your Decision Based on Price Alone

At first glance, all windows may look the same. However, you definitely get what you pay for when it comes to replacement windows. As mentioned above, your windows will protect you and your family for decades to come, which is why you should not skimp on them. Purchasing an inferior product that is likely to fail prematurely might actually end up costing you more money in the long run.

2. Not Doing Proper Research

Window technology has improved by leaps and bounds over the last few years, so it is important to do your research before purchasing new ones. These days, there are many glazing options, finishes and security features to choose from so be sure to do your due diligence before pulling the trigger.

3. Replacing Your Windows Yourself

Some articles and videos on the internet will have you believe that replacing your windows is easy. Unfortunately, this is far from the truth. If you do not have any experience in replacing windows, we highly recommend hiring a professional to do the job to avoid costly mistakes.

"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!"
