Providing the Best Products, Industry-Leading Warranties, and Unmatched Customer Service
We’re a Window and Door Company Like No Other
Kempenfelt Windows & Doors’ founder, Robert Maslen, started his home renovation career over three decades ago. By 1994, he recognized Barrie needed a local window company to serve its expanding community and offer high-quality, Canadian-made windows. He knew that a great product was only as effective as its installation, and he set out to provide it.
Over the years, the company expanded its offering to include patio, entry, and garage doors, rebranding as ‘Kempenfelt Windows & Doors.’ Our energy-efficient solutions withstand Ontario’s harsh weather, making us the trusted standard for quality products and exceptional service. We believe our vinyl windows are the best on the market, which is why we’ve been selling them since day one and bought into Euro Vinyl Windows.
Our commitment to exceptional quality and service has led to the well-known ‘Signs You See Everywhere.’ We’ve won a Readers’ Choice every year since 1999 and have been voted #1 multiple times by Best in Barrie, Barrie Today, Top Choice, and Three Best Rated awards. As Robert says, “We want what’s best for you, not just what’s best for us!”








Growing the Business with Canadian-Made Products You Can Trust
Co-owner Tony Miceli joined Kempenfelt in 2006 with more than 20 years of hands-on industry experience.
Working with Robert, Tony has enhanced operations and introduced new processes to reinforce the company’s commitment to customer satisfaction. “We train every team member to care for your home like we would our own. That’s why we spend time consulting with you on your project before we even begin showing you products. We want to ensure we get it right for you and your family.”
With a service area that spans from Orangeville to Keswick and Vaughan to Muskoka, our staff has grown from just a few to a team of more than 50 people.
