Considering replacing your windows but unsure about the process, duration, or timing?

From your initial quote to your final install, we’re with you every step of the way, so you know exactly what to expect and when. When considering a window replacement project, be sure to choose a company that values your business and treats you with respect. 

Here’s what to know.

What Is the Typical Window Replacement Process Like?

While every company is different, most professional window replacement projects follow a few key steps:

  1.  Initial Consultation & Quote:
    A knowledgeable consultant visits your home to understand your goals, inspect your current windows, take measurements, and answer your questions. You’ll get a detailed, written quote with options tailored to your needs and budget.
  2.  Final Measurements & Order:
    Once you decide to move forward, an installer typically returns to take exact, final measurements to ensure a precise fit. Your windows are then custom-built for your home.
  3. Installation Day:
    On installation day, the crew arrives on time, protects your home and belongings, removes the old windows, installs the new ones, and ensures everything is properly sealed, level, and clean. Most standard projects are completed in one to two days, depending on how many windows you’re replacing and the installation application. Bigger projects and/or custom projects can take more time.

Afterward, they’ll walk you through a final inspection and show you how to operate and care for your new windows.

When’s the Best Time to Replace My Windows?

One of the most common myths about window replacement is that it can only be done in mild weather.

In truth, professional installers can replace windows year-round, even in hot summers or cold winters.

In extreme temperatures, crews take extra care to minimize air loss by replacing one window at a time and working quickly. Many homeowners find that the energy savings from new windows start showing up on their utility bills right away, even if they are installed mid-winter or mid-summer.

So, the best time to replace your windows? Simply when you need them.

Do I Have to Replace All My Windows at Once?

Not necessarily. Some homeowners choose to replace every window at once for a uniform look and maximum efficiency. Others prefer to spread the project over time, starting with the oldest, draftiest, or most visible windows first.

Both approaches work, and many companies offer flexible financing to make either option easier on your budget. Be sure to ask about phased installation plans and how pricing may vary if you split the project. [link to finance article]

How Long Does the Entire Process Take?

From the day of your consultation to the final installation, most projects take about 4–6 weeks, though timelines can vary slightly depending on factors like:

  • The time of year (busy seasons may take longer)
  • Specialty or custom window styles
  • Manufacturer lead times (This can be the most significant factor in process time; check with the company to see if they make their own windows, or rely on a large brokerage company)

Once your custom windows arrive, installation itself is usually quick, often 1–2 days, depending on the size of the job.

Throughout the process, a good company will keep you informed so you always know what to expect next.
