“Failing to plan is planning to fail.”

Growth is a good thing, but it brings its own obstacles. As we continue to grow, we need to be intentional, organized, and prepared. Success will come from planning ahead, communicating clearly, and solving problems before they become bigger issues. Growth is an opportunity, but only if we lead through it well.

Welcome Steve and Jenny from Appleton to the Duncan’s world’s best customers family!

They chose Duncan’s Window and Door for beautiful new entry doors and Larson storm doors after meeting with other companies that only threw them a price without even showing them the products.

That’s what makes Duncan’s different.
We’re your neighbors. We live here, work here, and serve here. Thank you for trusting Duncan’s with your home!

This Memorial Day, we honor the heroes who gave everything for the freedoms we enjoy every single day. Behind every flag flying proudly is a story of courage, sacrifice, and a family forever changed.

Today is more than a long weekend. It is a reminder that freedom comes at a cost paid by brave men and women who never made it home. Their sacrifice will never be forgotten, and their legacy lives on in the country they fought to protect.

As we gather with loved ones, let us pause to remember those who made the ultimate sacrifice and keep their families in our prayers.

From our family at Duncan’s Window & Door to yours, thank you to our fallen heroes. We remember you today and always. 🇺🇸

🥩 NO GIMMICKS. JUST FREE MEAT. 🥩

At Duncan’s Window & Door, we believe supporting local should be simple. ❤️

So this Friday & Saturday, we’re teaming up with another incredible family-owned business - Beck’s Meat Processing-to give back to the community that supports us every day.

📍 Available at ALL 3 Beck’s locations:�• Clairville Road�• Downtown Oshkosh�• Kaukauna

🔥 FIRST 20 customers at EACH location on Friday 22nd & Saturday 23rd: That’s 120 family’s getting some high quality meats for free.

Buy 2 pounds of hamburger, sausage, or wieners…�👉 Duncan’s Window & Door will buy your OTHER 2 pounds.
That’s FOUR pounds for the price of TWO. 🥩🥩

Because quality matters.
Just like Duncan’s believes in quality windows and doors, Beck’s believes in quality meats. Since 1996, Terry & Carol Beck have built Beck’s into a trusted local favorite known for quality products, clean facilities, and friendly service.

That’s local supporting local. 👊
Thank you for trusting Duncan’s Window & Door with your homes and families over the years. This is one small way we can give back.
