What to Expect During a New Window Installation: A Step-by-Step Walkthrough
A new window installation is one of the more impactful upgrades you can make to your home, but if you’ve never been through the process before, it’s natural to wonder what exactly happens on the day your crew shows up. We’ve been doing this for over two decades in Marietta, GA and throughout metro Atlanta, and we find that homeowners feel a lot more comfortable when they know what to expect from start to finish. So here’s an honest, straightforward walkthrough of how a professional window installation actually goes.
Before Anyone Picks Up a Tool
Good preparation makes the whole project smoother. A day or two before installation, it helps to clear the area around each window, move furniture a few feet back, take down any window treatments, and remove fragile items from nearby shelves. Our crews are careful and respectful of your home, but giving them clear access from the start means less time and less stress for everyone involved.
On the morning of installation, your crew will do a quick walkthrough with you, confirming which windows are being replaced and reviewing any specific details from your order. This is a great time to point out anything you want them to know about your home before work begins.
Removing the Old Windows
The first physical step is taking out your existing windows. This involves carefully removing the interior trim, then pulling out the old window unit from its frame opening. Our team works methodically here. Depending on how the original windows were installed and the age of your home, this part can take anywhere from fifteen minutes to a little longer per window.
Once the old unit is out, we inspect the rough opening carefully. This is something that separates a quality installation from a rushed one. We check for any signs of water damage, rot, or compromised framing. If we spot anything that needs addressing, we’ll let you know right away rather than covering it up and moving on.
Installing the New Window
With a clean, solid opening ready, the new window goes in. We set the unit level and square, which is critical. A window that isn’t perfectly plumb and square will have problems over time, whether that’s difficulty opening and closing, air leaks, or water infiltration. Our crews, some of whom have more than 20 years of field experience, take this step seriously because it’s where craftsmanship really shows.
Once the window is positioned correctly, it’s secured, shimmed where needed, and sealed around the perimeter. For homeowners in Atlanta, GA and the surrounding communities, proper sealing matters a great deal given our humidity and seasonal temperature swings. We use flashing and weatherproofing materials to create a tight barrier against moisture and air.
As an authorized Andersen installer, we follow the specific installation requirements for Andersen windows, which matters for both performance and warranty protection. Whether you’re getting a classic double-hung, a picture window, or a sliding unit, the installation process is customized to the product and your home’s specific conditions.
Finishing and Cleanup
After the window is in and sealed, interior trim is reinstalled or replaced as needed. Your crew will also do a final check on the operation of each window, making sure it opens, closes, and locks the way it should. Before we leave, we clean up the work area and haul away the old windows and any debris. We think it’s only right that your home looks better when we’re done, not like a job site.
What Happens After Installation
Once everything is installed, we’ll walk through the completed work with you so you can see the results and ask any questions. We cover warranty details at this point too. Our installations come backed by both product and labor warranties, so you have real peace of mind going forward.
If you notice anything in the days after installation, whether it’s a question about how a window operates or something you just want a second set of eyes on, don’t hesitate to reach out. We serve homeowners across Marietta, Atlanta, Roswell, Kennesaw, Alpharetta, Acworth, and surrounding areas, and standing behind our work is something we take genuinely seriously after more than 40 years in this industry.
