For 25 years, Jantek Windows has been making windows and patio doors to your specifications and installing them at your home or business. We’re celebrating this mile-marker anniversary with kudos to our employees. Everyone involved in the operation is an employee — not a contractor. That’s just one of the ways we ensure our products are the best in the industry.
We have our own 80,000-square-foot factory in Medford, NJ, where our employees work hard to make high-quality, energy-efficient windows. You don’t have to take our word, check out our Facebook page and Google Reviews on what our customers have to say .
