JEREMY THE WINDOW GUY
Honest help for homeowners who want better windows - without the pressure.

If your windows are drafty, outdated, hard to open, or just making your house feel older than it should - you’re in the right place.
I’m Jeremy Stroik, though a lot of folks know me as Jeremy the Window Guy. I work with homeowners across Oshkosh, Neenah, Menasha, Appleton, Fond du Lac, Omro, Winneconne, New London, Waupaca, Berlin, Green Lake, and the greater Fox Valley area to help them make smart, low-pressure decisions about replacement windows with a little door talk sprinkled in too.
This page isn’t here to drag you into a three-hour sales pitch. It’s here to help you get to know who I am, why I do this, and why I’m proud to help homeowners through Duncan’s Window & Door.
WHY HOMEOWNERS LIKE WORKING WITH ME
Clear answers. Good communication. No weird pressure.
Let’s be real - replacing windows is not exactly how most people want to spend their free time.
It’s a big decision. There are a lot of options. And if you’ve already gotten quotes, you probably know some companies make the process feel way more stressful than it needs to be.
That’s not how I do things.
When I show up, my goal is simple: make the process feel clear, honest, and easy to understand.
I want homeowners to feel like they can ask questions, think things through, and make the right decision for their home without feeling pushed into something they’re not ready for.

That’s the stuff people seem to appreciate most
about working with me:
-
I explain the process in a way that makes sense
-
I communicate well and follow up when I say I will
-
I answer questions without making people feel dumb
-
I stay organized and keep things moving
-
I care about making the process feel seamless and stress-free
At the end of the day, I’m not trying to “close” you. I’m trying to help you feel confident about what you’re doing in your home.

WHY I WORK WITH
DUNCAN’S WINDOW & DOOR
Because I trust the people, the process, and the work.
I get asked this sometimes - and it’s a fair question.
Yes, I work for Duncan’s Window & Door. I also help drive a lot of the voice behind our Facebook content and messaging. But the bigger reason I’m proud to be connected to Duncan’s is simple:
I trust the people behind the name.
That matters to me.
Because if I’m going to walk into your home and attach my name to a project, I need to believe in the team doing the work. I need to know the craftsmanship is real. I need to know people are being treated well. And I need to know that if something needs attention, the company is going to show up and make it right.
That’s what I’ve seen here.
What I like about Duncan’s:
-
Free Estimates
-
Strong communication
-
Respectful, detail-oriented crews
-
Real craftsmanship
-
An in-house team that shows up when they say they will
-
People who care about doing the job right
I’ve seen what happens behind the scenes, and that’s why I feel good saying this: if you’re thinking about replacing windows, I’d be honored to help you through Duncan’s.
WHAT I HELP HOMEOWNERS WITH

Replacement windows first - and a little door talk too.
Most of the time, people reach out because something already feels off.
Maybe the windows are drafty.
Maybe they’re fogging up.
Maybe they stick.
Maybe certain rooms are always too cold in the winter or too warm in the summer.
Maybe the house just feels tired and ready for an update.
Replacement Windows
This is the main thing I help homeowners with.
If your windows are worn out, inefficient, or making your home less comfortable than it should be, I can help you sort through your options and figure out what actually makes sense for your house, your budget, and your goals.
A Little Door Talk Too
Windows are the main focus here - but if your project also includes a front door, patio door, or another entry point, I can help with that conversation too.

WHAT REAL HOMEOWNERS ARE SAYING
Kathy Schrader
"Extremely happy with Duncan’s Window & Door! Jeremy was great with our quote and with explaining the entire process. They were very comparable to the other companies that came out for quotes. The crew was wonderful to work with. Very respectful and detail oriented. We would highly recommend them to anyone we know looking to replace their windows!”
Colette Ramsey
“Highly recommend this company! Jeremy, Ben, and Micah were fantastic to work with... professional, friendly, and great communicators throughout the entire process. They paid attention to every detail, showed up when they said they would, and delivered excellent results. I wouldn’t hesitate to work with them again or recommend them to others.”
Brandon Ruis
“Duncan’s Window & Door LLC is in a tier of its own as far as I’m concerned. Jeremy was awesome getting us started with the process and answering all of our questions we had along the way. He was well organized and made the process a breeze... Their character and work shines a bright light on the company.”
Katie Willers
“We have been working with Jeremy at Duncan’s Window and Door and it was an absolute dream.
