ABOUT JANTEK INDUSTRIES, LLC

Established in 1995, Jantek was determined to be an industry leader in the vinyl replacement window and patio door industry. The goal was to build a company that makes the window and patio door buying and installation process easy, trustworthy, and reliable.

The business model was built around manufacturing well made, custom sized, energy efficient replacement windows and sliding patio doors at a fair price to their customers. Jantek does not use hard-sell or deceptive sales tactics.

To do this, an expert team was assembled that included, engineers, product specialists, and installers. Manufacturing was streamlined to ensure their products were accurate and turned around quickly.  

                                    TELE-ESTIMATE

In 2019 Jantek was met with a new challenge when in home estimating was temporarily prohibited. But Jantek was in a unique position; because they manufactured and installed their own brand of vinyl replacement windows and sliding patio doors, and there is no middleman to contend with, they could accurately quote costs without having to visit the home. The on-line TeleEstimate form takes less than 5 minutes to complete and doesn't require measurements to get you a quote. 

ENERGYMISER

Jantek rolled out their EnergyMiser product line in 2022 as part of their continuous improvement, comprehensive approach to manufacturing. EnergyMiser combined intelligent engineering with superior materials. Multi-chamber, reinforced frames, fusion welding, and triple pane low-E glass are just some of what allows Jantek to achieve their superior ratings.

Jantek continually improves their product lines and processes. Scroll down to read the reviews and see for yourself why Jantek is considered one of the best replacement window companies in the area.

What Our Customers Have To Say

I had windows installed by a different company a couple of years ago and the process was very time consuming and painful. Every company would not give a price over the phone or internet which resulted in a couple of hours of high pressured sales pitches. When I needed to replace my sliding patio door I knew I didn't want to go through my previous experiences and remembered my neighbor used Jantek and was completely satisfied with their work. So I submitted an online request for a quote, and received it within 24 hours. I went into the Medford showroom to check out the product and was pleased with the quality of the door. Within a couple of weeks I had a new well-crafted sliding door for the holidays. Ryan who installed the door did a great job. I highly recommend Jantek Windows and I am completely satisfied!
