3 Things to Consider When Replacing Windows During the Fall

When the temperature drops, many homeowners seem to think that certain home improvement projects can no longer be undertaken unless it’s an emergency. While the warmer seasons are arguably the most ideal time of the year to replace your windows, there really is no reason why you can’t have energy-efficient windows installed during the fall if you are working with an experienced contractor. Here are a few things you should consider if you are leaning towards replacing your windows this autumn.

Replacing Windows

1. Scheduling

If you are looking to have your windows replaced this fall, be sure to have your contractor come by on a warm, sunny day if possible. You should schedule the job mid-morning to give the materials a chance to warm up and expand. Keep in mind that some sealants need at least 24 hours to set before being exposed to water so be wary of rain.

2. Caulking

There are many caulks available on the market, but for a fall windows installation project your best bet is to go with a silicone-based product instead of latex or acrylic. Silicone-based caulking has more effective adhesion in colder temperatures and is also better at waterproofing and weatherization.

3. Joint Movement

For better results, ask your window contractor to use a sealant that has exceptionally high joint movement. Joint movement capability is usually expressed as a measurement that is labeled on the bottle. A caulk that is labeled as minus 25% movement will perform better during a cold-weather installation.

"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!"
