Arch City Window Doubles Business as Pella Certified Contractor

Siding Unlimited has long been known for high-quality exterior remodeling in Wisconsin, offering everything from windows and doors to roofing, decking and siding. But according to Eric Brown, partner at Siding Unlimited, becoming a Pella Certified Contractor brought new momentum to their already thriving business.

We spoke with Eric to learn how being a Pella Platinum Premier Certified Contractor supports his team, improves customer confidence and helps them grow year after year.

Siding Unlimited first joined the Pella Certified Contractor program because of the alignment between their brand and Pella’s product excellence. “The products Pella offers are a fantastic blend for what we do,” Eric says. “They match well with our services and allow us to move forward with confidence in the home.”

Yet, one of the biggest advantages? The power of co-branding. “We’ve used the Pella brand alongside ours in the Milwaukee and Madison markets, and that’s really boosted our success,” he explains. By combining brand recognition with their own reputation for service, Siding Unlimited creates a professional, trustworthy first impression for homeowners.

While co-branding helps drive awareness, Eric says the Certified Contractor program delivers value in many other ways too. “It’s not just about the co-op dollars — although that’s a great benefit,” he laughs. “We also gain access to tools and partnerships that support every aspect of our business, from CRM and customer communication to website strategy.”

The co-op dollars, earned based on purchase volume, help the business reinvest in marketing efforts that drive even more growth. “It’s essentially free money. Why wouldn’t you take advantage of it?”

Eric emphasizes that the value of the program goes beyond numbers. Since joining the program, he’s seen measurable growth not just in revenue, but in how his team trains and operates.

“It’s changed the way we go to work every day,” Eric says. “Our people feel proud knowing they’re part of something bigger — not just working for Siding Unlimited, but with a brand like Pella too.”

While Eric doesn’t pinpoint exact numbers, the growth is clear. “We’ve been co-branding with Pella since the beginning, but once the contractor program launched in 2017, it took things to a new level,” he says. “Since then, our business has grown immensely.”

From added credibility to expanded resources, the benefits of the program have impacted every area of the company.

One of Eric’s favorite parts of the program is the annual Pella Certified Contractor Summit. “It’s not just a few days away from home — it’s a chance to really learn and grow,” he says. From breakout sessions to informal conversations with other contractors, Eric walks away with insights he can apply right away. “We’ve made changes to our business because of things we’ve learned at the summit. It’s a valuable experience every time.”

From co-branding and co-op support to training and networking, the Pella Certified Contractor program helps contractors across the country level up their entire business.
