Faith. Family. Community. Craftsmanship.
I’m Jeremy Stroik—husband, father, follower of Christ, and the proud community-facing voice of Duncan’s Window & Door.
My mission is simple: serve people with integrity, lead with faith, and help Wisconsin families build homes and legacies that last. I believe a home is more than a roof and walls. It’s where marriages grow, kids are raised, memories are made, and future generations are shaped.
That’s why every quote I give, every conversation I have, and every home I step into is guided by three things: honesty, excellence, and genuine care for the people inside.
At Duncan’s, I’m blessed to serve alongside true in-house craftsmen who take pride in their work—never subcontracted, never cutting corners. Together, we deliver craftsmanship like no other, backed by real warranties, real customer care, and a “no gimmicks” experience people can trust.
But windows and doors are only part of my story.
I’m passionate about strengthening marriages, supporting local businesses, encouraging families, and building a community rooted in faith, generosity, and purpose. Whether I’m filming a Legacy Dad video, praying for a family, shouting out a local shop, or helping someone navigate a home project, my goal is always the same: Leave people better than I found them.
I’m grateful to serve the Fox Valley, Oshkosh, Appleton, Green Bay, and the surrounding communities—and even more grateful for the relationships, stories, and families I get to encounter every day. Faith fuels my purpose. Family shapes my why. Community drives my mission.
Craftsmanship is the work of my hands. I’m honored to serve the world’s best customers—and to help you open the door to what’s possible for your home and your future.

Why I Trust Duncan’s Window & Door
WITH MY OWN HOME
From one homeowner to another:
here’s why I stand behind this team.
I’m “Jeremy – The Window Guy,” and most days you’ll find me helping homeowners all over the Fox Valley figure out what to do with their drafty, tired, or just plain outdated windows and doors.
I don’t just work at Duncan’s Window & Door.
I stake my name, my reputation, and my relationships on the work we do.
If you’ve ever wondered, “Okay Jeremy, but why Duncan’s?”
This page is my honest answer.
In-House Craftsmen,
Not Random Subcontractors
There’s a big difference between “some crew the company sent” and a team that actually carries the company’s name on their chest.
At Duncan’s:
-
The installers you see at your home are Duncan’s employees, not a rotating list of subs.
-
They’re trained under the same standards, leadership, and expectations I see every week.
-
They know they’re not just installing a window—they’re installing something with their name and our reputation attached to it.
That means you’re not left guessing who’s in your house or who’s responsible if something goes sideways. It’s our team, our work, and our responsibility.
No Pressure. No Games. No Sales Theater.
Built for Wisconsin Weather
(Not Just a Brochure)
If you live here, you already know: Wisconsin is not gentle on houses.
We’re talking:
-
Freezing cold winters
-
Humid summers
-
Storms that show up out of nowhere
-
Big temperature swings in a single week
The products I recommend through Duncan’s are chosen specifically for this reality—not just because they look good in a catalog.
We look for:
-
Frames and seals that actually fight drafts
-
Materials that don’t freak out when humidity hits
-
Glass that helps stabilize inside temps
-
Install methods that stand up to what our climate does year after year
If it doesn’t perform here, I’m not interested in selling it.
Energy Efficiency That Actually Makes A Difference
A window is more than “it looks nice now.”
Done right, it’s a long-term investment in how your home feels and what you pay every month.
The right setup can mean:
-
Lower monthly energy bills over time
-
Fewer drafts and fewer weird hot/cold spots in random rooms
-
A furnace and AC that don’t have to work like they’re training for a marathon
-
Comfort that doesn’t disappear every time the temperature changes
Will a single window change your life? Probably not.
Will a well-planned project across your home make a real difference? Absolutely.
Windows & Doors That Fit Your Home
Not every house wants the same look.
Some are classic. Some are modern. Some are a mash-up of “farmhouse, but make it 2026.”
One of my favorite parts of this job is helping you pick something that actually fits your home and your style, not just whatever was on sale that week.
We’ll talk:
-
Frame styles: clean and modern vs. more traditional profiles
-
Colors and finishes: outside curb appeal, inside vibes
-
Glass options: privacy, efficiency, and style
-
Hardware: the small details that finish the look
My promise? I’ll give my honest opinion and help you land on something that makes sense for your house, your budget, and your long-term plans.
One Team, One Warranty, No Finger-Pointing
Here’s something homeowners almost never ask about upfront—but it matters a lot:
When something goes wrong, who owns it?
Because Duncan’s:
-
Buys the product,
-
Installs the product, and
-
Services the product,
You’re not going to get bounced between a manufacturer, a subcontractor, and a call center.
If there’s an issue with your windows or doors, you call us.
We show up.
We deal with it.
No blame game.
No “that’s not our side of the warranty.” Just one team standing behind what we installed.

LET'S TALK WINDOWS & DOORS
Jeremy-Approved Businesses
When I recommend a business, it’s not because of a sponsorship, affiliate link, or back-room deal. It’s because they earned it the old-school way: by doing the job right, treating people well, and standing behind their work when no one’s watching.
Jeremy-Approved Businesses are companies I’d trust in my own home and with my own family. They’re customer-focused, values-driven, and deeply rooted in the communities they serve. These are the people I’m proud to point homeowners, families, and leaders toward when they ask, “Who do you actually trust?”
What makes a business Jeremy-Approved?
-
They do quality work and don’t cut corners.
-
They communicate clearly and show up when they say they will.
-
They treat customers like people, not transactions.
-
They care about faith, family, and community—not just profit.
This isn’t a paid list.
It’s a trust list.
If you’re looking for businesses built on integrity and craftsmanship, start here. And if you’re a local business owner who lives this out every day and wants to connect, I’d be honored to hear your story.
