Our Window & Door Installation Process
Our proven, step-by-step installation process makes it easy to get the results you want—without stress or surprises.
1. Meet with a Design & Energy Expert
It all starts with a complimentary in-home or virtual consultation. Our design and energy experts take the time to understand your style preferences, energy goals, and budget.
As part of our door and window replacement process, you’ll receive tailored recommendations and a transparent quote—no pressure, just smart solutions that fit your home.
2. Professional Project Management
Once you’re ready to move forward, a dedicated project manager will walk you through our curated selection of windows and doors. We take precise measurements to ensure a perfect fit, helping you avoid common issues like air leaks, misalignment, or costly rework later on.
3. Quality Window or Door Installation
Our certified installers follow all manufacturer specifications to ensure correct sealing, insulation, and operation. You’ll notice the difference in quieter rooms, reduced drafts, and a clean worksite that shows respect for your home.
4. Project Cleanup & Walkthrough
After installation, our crew thoroughly cleans the workspace, removing all debris, packaging, and old windows or doors. Before wrapping up, we conduct a complete walkthrough with you to ensure everything looks and functions exactly as expected. We don’t consider the job finished until you’re fully satisfied with the results.
5. Warranty & Ongoing Support
You can have peace of mind knowing your investment is protected. We offer manufacturer warranties on all Marvin and ProVia products, as well as labor warranties on our installation work. If any issues arise in the future, our support team is just a phone call away. Learn more in our resource center.

See Why Lake Forest Homeowners Choose Us
I would definitely recommend
Right from my first phone call to speak to and have a representative come out to look at what I need and would like.
Dan Brander came out and made me feel very comfortable with what he evaluated of what needs to be done, he was a great help with helping me choose the door for my needs and my wants.
I never felt any pressure to choose something, he kept me within my budget and gave me a quality product.
After the door was ordered, I received consistent messages or phone calls from Steve Greene, my project manager as to what the status was on my door.
When the door was ready to be installed, I had other projects going on with my home and they worked with me to schedule a time for installation. I received multiple reminder calls to confirm installation.
The day of installation, the door was delivered on time just as they said it would and when the installer Chris arrived, on time as well. He was very polite and professional. His work ethic was phenomenal.
I love my new door. Thanks everyone at Next Door and Window.

Frequently Asked Questions
How long do I have to wait for my new windows or doors?
Timelines can vary depending on the products you choose and the time of year. In most cases, homeowners can expect their new windows or doors to be installed about 6 to 10 weeks after purchase. Once your selections are confirmed and measurements are taken, we’ll provide a clear timeline so you know exactly what to expect at every step.
When do I need to replace my windows?
You may notice that your home feels drafty, especially near older windows, or your energy bills have increased for no apparent reason. Condensation between panes, frames that stick, or just an outdated appearance can also be signs it’s time for a change. If you’re experiencing any of these issues or would like a second opinion, our team is happy to evaluate your current windows during a consultation.
Do you replace windows in HOAs?
We do. We regularly work with homeowners in HOA-regulated neighborhoods and have a thorough understanding of the approval process. Our team can guide you through compliant design options and provide the product specifications or documentation your HOA may need for a seamless approval.
Do I need to take off work for installation?
Not necessarily. While someone over 18 must be present when our team arrives and again at the end of the installation for a final walkthrough, you don’t need to stay home all day. We’ll work efficiently and communicate throughout the process to make things as convenient as possible.
