What We Offer

Our Services

Window Installation & Replacement

Whether you're upgrading for energy efficiency, comfort, or curb appeal, we deliver precise measurements and a flawless fit. We work with a wide range of styles and materials to ensure your new windows complement your home while providing long-lasting performance.

Exterior Door Installation & Replacement

From entry doors to patio and sliding glass doors, our focus is on security, durability, and style. Every installation is completed with careful attention to detail, proper sealing, and a clean finish that performs reliably in all seasons.

Custom Fit for Existing Homes

No two homes are the same. We specialize in adapting modern windows and doors to fit existing structures including older homes with unique or non-standard openings. We deliver seamless results with minimal disruption.

Energy-Efficient Upgrades

Our energy-efficient window and door solutions are designed to reduce drafts, improve insulation, and lower energy costs. We guide homeowners through the best options, focusing on performance, comfort, and long-term value.

Professional Trim & Finishing Work

A quality installation goes beyond the product itself. We offer detailed interior and exterior trim work: clean caulking lines, precise finish carpentry, and final detailing, so every project looks as good as it performs.

Full-Service Installation Experience

From the first conversation to the final walkthrough, we take care of everything. We show up on time, keep your home clean, communicate clearly, and don't leave until you're happy with the result.

Our Story

Meet Barbara Wendt

Hi, I'm Barbara Wendt. I'm the proud owner of Wendt Windows & Doors, a Wisconsin native, and someone who understands just how much a home means to the people inside it.

For over 20 years, I've worked in this industry with one goal in mind: to help families feel safe, comfortable, and proud of where they live. This work is personal to me. I've been married for over 30 years, I'm a mother of two amazing children, and a proud Mimi who treasures every moment with my grandchildren. Those roles have shaped the way I treat every customer who trusts me with their home.

I built this company from the ground up with hardworking families in mind. The kind of people who value honesty, expect quality, and deserve to be treated with respect. As a woman-owned business, I bring a different perspective. I pay attention to the details, listen first, and follow through on every promise. No pressure. No shortcuts. Just genuine service and craftsmanship you can count on.

"Built with heart, for the hearts inside."

When you choose Wendt Windows & Doors, you're not just getting experience. You're getting someone who truly cares about doing the job right, treating you fairly, and helping you create a home you love coming back to.
