Cold weather and holiday plans put a deadline on many window projects. You can get new windows installed before winter if you place your order 8 to 10 weeks ahead. That is the timeline we give every homeowner, from the day you order to the day your windows go in.
Weather, special order products, and the size of your project can all stretch that schedule. Here is what affects your installation date and how we keep projects moving.
How Long Does It Take to Get New Windows Installed Before Winter?
Timing is the first thing to think about when you start a window project. Most homeowners have a date in mind, such as a holiday gathering, a wedding, or the start of cold weather.
Our Standard 8 to 10 Week Timeline
We tell every homeowner to expect 8 to 10 weeks from order to installation. Many of our projects are finished in 6 to 8 weeks. We still prepare you for the longer timeline so your plans hold up.
Finishing early is a bonus. Our goal is to never run past the estimate.
Order Early to Get New Windows Installed Before Winter
Count backward from your target date. If you want everything done before a family event or the first freeze, place your order at least 10 weeks ahead. That buffer gives us room to handle the factors we can’t control.
Pro Tip: Let us know about any special order options before you set your date. Some glass types and frame colors add time to the schedule.
What Can Delay Your Window and Door Project
Some factors are outside our control. Knowing them upfront helps you plan a realistic installation date.
Rain on Installation Day
Say your windows arrive 6 or 8 weeks after ordering and your install is on the calendar. If it rains that day, we will not open up your home. We reschedule instead.
We book our crews about a week out, so the very next day is usually taken. A single rainy day can push your project back further than you might expect.
Special Order Products and Custom Doors
Certain options take longer to produce. These include:
- Leaded glass and designer glass
- Black frames, which are very popular inside and outside right now
- Tempered glass
Entry doors are highly custom, so we quote 8 to 10 weeks for those as well. The more ornate the door, the longer it can take.
Key Takeaway: Weather and specialty products are the two biggest reasons a window replacement runs past its original date. Order early if you want black frames or leaded, designer, or tempered glass.

How We Schedule Multi-Day Installations
Larger homes often need several days of work. Our scheduling process protects your home and keeps your project on track.
Keeping Your Project Consecutive
For a big job, we might set aside five days at your house. We usually don’t book that crew for the following week until we know how your project is going.
Here is how that works:
- We reserve the full five days for your home.
- On day two or three, we check the forecast and our progress.
- If the weather looks good and the work is on pace, we finish within the five days.
- If rain is forecast every day, we keep the following schedule open so your project can run long without a gap.
We never remove windows in the rain. Neither of us wants that liability. We also avoid splitting your install across scattered days, such as Monday and then Thursday. Working consecutively gets your project completed sooner.
When Exceptions Come Up
Occasionally, we make a firm commitment months in advance. One example is a family returning from a winter away who needs windows in before an anniversary party.
If the job before theirs runs into weather delays, we let the homeowner on that job know upfront which day we must step away. Then we return right away to finish their project.
Pro Tip: If your home needs a multi-day installation, ask us how the forecast could affect your schedule. We will keep you updated from the first day to the last.
Book Early for a Smoother Installation
Early planning is the simplest way to avoid delays on a window replacement before the cold sets in.
The Short Answer
Yes, you can have your windows replaced before winter. Plan on 8 to 10 weeks from order to installation, and allow extra time for rain delays, black frames, specialty glass, or custom doors.
