Our Story
Over two decades helping Michigan homeowners make better decisions about their homes — and the reputation to prove it. This is the story of Jeff Haring and how a classroom career became The Window Professor.
The Name Behind the Brand
Before Jeff Haring ever measured a window or swung a hammer, he stood in front of a classroom. Jeff spent years as a high school teacher — and when he made the move into home improvement, he brought the one thing that almost nobody in the trades ever does: the instinct to teach first and sell second.
"I'm not a salesman. I never have been. My job is to help you understand what you're buying and why it's right for your home. If I do that well, the rest takes care of itself." — Jeff Haring, Founder
Homeowners started calling him "the professor" not because it was on a truck door — it was because sitting across from Jeff at their kitchen table felt different from every other contractor they'd met. He explained the difference between product grades. He told them what questions to ask competitors. He was honest about what their home actually needed — and honest about what it didn't.
That's not a tagline. It's the literal reason his company is called what it is. The name came from customers. That's the kind of name you can't buy.
That philosophy built a company from the ground up — and it's what still drives every estimate, every install, and every follow-up call today. When Jeff shows up at your door, you're not getting a salesman who went into contracting. You're getting a teacher who knows his craft inside and out — and will make sure you do too.
Jeff Haring started his career in a classroom — a real one. He was a high school teacher. And when he eventually made the move into home improvement, he carried that identity with him.
Most contractors walk into an estimate with a goal: close the job. Jeff walks in with a different goal: make sure the homeowner actually understands what they're buying. He'll explain the difference between product lines. He'll tell you what the cheaper option gets you and where it falls short. He'll point out things other contractors might gloss over — not because it helps him close faster, but because he believes an informed homeowner makes a better decision.
When you hire The Window Professor, you're not getting a salesman who learned the trades. You're getting a teacher who mastered them — and will make sure you understand every decision along the way.
What You'll Actually Notice
Jeff doesn't just quote jobs. He explains what you're buying, why it matters for your specific home, and what questions you should be asking any contractor you talk to. That education isn't a tactic — it's just how he was built.
The Window Professor runs experienced, full-time installation teams who do this work every single day. When your project starts, the people who show up are the same people who finish it. No strangers, no surprises.
Windows. Siding. Decks. You don't have to coordinate multiple contractors with multiple timelines. The Window Professor handles all of it — which means someone's always accountable for the full scope of the job.
Jeff's teams have been working in the same communities, on the same streets, for over two decades. That local track record means we know the specific challenges and building conditions in your area — and we're not going anywhere.
