Install Replacement Windows in Fall or Winter

Of course, there are times when you can’t get around a cold-weather installation. If your window is broken or cracked, you can’t exactly wait around until spring to put in a new one. If that’s the case in your home, all is not lost. You just need to take a few precautions to make sure that the window is replaced safely.

  • Have your contractor come on a sunny, warm day if possible. Schedule the job for mid-morning—this will give the materials a chance to warm up and expand. Be wary about a rainy forecast—some sealants need up to 24 hours to set before they can be exposed to water. If it has recently rained, ask your contractor to allow the exterior surfaces to dry before beginning the project.
  • Make sure your contractor applies silicone-based caulk around the window instead of latex or acrylic. Not only will it more readily adhere to the window in colder temperatures, it’s also better at waterproofing and weatherization—which will make your heating and cooling work more efficiently and save you money on your energy bills, too.
  • For exceptionally high performance, ask your contractor to use sealant that has high joint movement capability. This is usually expressed as a measurement on the bottle—a caulk with plus or minus 25 percent movement will perform better when installed in cold weather than one with plus or minus 12 percent.


If you have to do your replacement in the dead of winter, have the contractor work on one window at a time to keep your home from becoming an icebox. If you’re installing a larger window or the types of windows that have multiple panels of glass—such as a bay window—ask the contractor to cover the width of the opening with floor-to-ceiling plastic, so you can help root out drafts while the installation is in progress. And close off interior doors that lead to the room—that way, you can limit the effects to just one part of your home and keep the rest of your home nice and warm.

Warm Months

You won’t be letting in chilly drafts that will force you to pump up your heat—and therefore your heating bill! This is especially true if you’re replacing multiple windows. Late spring, throughout the summer, and early fall are great times to have windows installed, but this is when most people have replacement windows installed. If you don’t mind competing a little bit to schedule a date to have your windows put in, here are a few of the things you should know about warm month installations.

There are several reasons to do your window replacement when it’s warm.

  • Warm months are great because they are warm, right? Well, the warmth can put some people off to having windows installed, especially if it is the middle of the summer. It isn’t as easy keeping the hot out as it is to keep the cold out. Why? Because hot is often accompanied by humidity. Fortunately, the ease of access that warm months provide makes warm month installations even faster than cold month installations, and your installer will have those windows in fast.
  • Some people worry about heavy rains or thunderstorms keeping them from getting their windows in. This is definitely something to think about in the warm season. Rain can cause window installations to be harder to schedule, but scheduling early can help to avoid the complications foul weather can throw into the mix.

Preparing for Window Installation

No matter what time of year you schedule your home windows replacement, the project will come off a lot better if you prepare for the job before your contractor arrives. Here’s a handy checklist that will make installation run as smoothly as possible:

  • Cut back any tree branches or shrubs that may create obstacles for your installer, particularly in the spring and summer when foliage is full and more likely to get in the way.Window installer with window
  • Clean the area surrounding the window, since dust and pollen on uncleaned surfaces can mix with caulk and cause problems in spring and summer.
  • Purchase several drop cloths and floor-to-ceiling plastic sheeting to protect your home from dust, paint, and debris—and to keep heating and cooling from escaping while the contractors work.
  • Remove windows, curtains, blinds, and any other window treatments to avoid damage.
  • Clear furniture away from the windows—but avoid creating an obstruction between the window and the front door. Your installer should be able to enter and exit your home without having to navigate an obstacle course.
  • If you have a security system with window sensors, deactivate it before your contractor begins working.
  • Keep pets secured in a room away from the work. Installers are hauling heavy materials in and out of your home and may not have time to keep an eye out for Spot.
