Company History

Almost 70 Years of Dedication to Beauty and Performance

Family owned and managed since its establishment more than half a century ago, the Semling-Menke Company operates under a single guiding philosophy: to produce the best quality windows and patio doors possible.

Innovation at the forefront of advancing technology is part of how generations of the Semling family have achieved this goal. As importantly, performance and beauty in the final product is determined by attention to detail at every stage of production. From selecting the wood, to doing our own millwork and laminating, through every phase of construction, our state-of-the-art designs are expertly crafted by skilled employees. All of the extra effort ensures your utmost satisfaction when you select Semco.

We're Proud Of Our Products And The People Who Produce Them.

Because the Semling name goes on each and every product we produce, we are more than a little particular about how each product is designed, what materials go into it, and how it is assembled into the finished product. That is why we carefully design each window and door to provide maximum performance over many years.

We do this by using only the finest materials that we produce ourselves, or have made to our exacting specifications by outside suppliers.

We then combine state-of-the-art and quality design with expert and careful assembly by skilled employees with generations of manufacturing experience.
