K&H Custom Window Treatments has been covering the windows of businesses in Pennsylvania since 1986. That’s a lot of shades, blinds, drapes, privacy curtains, and stage curtains – enough to guarantee that you’ve seen our work in one venue or another. Our work can be seen in corporate offices, healthcare facilities, senior living facilities, education facilities, restaurants, and apartments.

Like most good things in life, the K&H story begins with hard work, persistence, and a really great mom. Sandy Kuhns and her mother, Norma Heller, began the business with $500, a well-worn sewing machine, a dad, Donald, in the stage-rigging business, and solid accounting know-how. Although most early clients were residential, they soon worked their way into commercial projects by persistently calling on contractors and bidding jobs. Just getting their foot in the door took determination as Sandy recalls the challenges of being females in a predominantly male-owned business. Their professionalism and consistent effort paid off. Forty years later, the first contractor to take a chance on the young business remains one of their strongest clients.

When the PPL Building lit up on Thanksgiving Eve, we all knew the holidays had begun in the Lehigh Valley. What many people don’t know is that K&H played a special role in ushering in this holiday tradition. In the 1930’s, PPL started the popular display using light bulbs and a colored cellophane wrap in each window. Then, after an 18-year hiatus, they turned to K&H to reinstitute the holiday light tradition in 1990. Sandy remembers, “We were given only a few weeks to come up with a method for projecting the color outside the building.” After noticing several businesses with lit awnings, Sandy realized that back-lit awning fabric could be used to produce the color effects here as well. Now, all they had to do was plan the designs, buy the fabric, manufacture, and install all those shades — in two weeks! The plan was a success and the colored shades remained in place, undergoing enhancements like LED lighting and computerized timers over the years. This long standing holiday tradition ended in 2025 but it remains a beloved memory both for Lehigh Valley residents and the team at K&H.

K&H is still a family enterprise, along a team of diligent and dependable employees. Although Norma is no longer with us, Sandy remains the President and Design Director. Sandy’s two brothers, Mark Heller and Craig Heller dedicated their careers to the family business as well. Mark retired at the end of 2019, after more than 20 years as estimator, project manager, and partial owner for K&H. Craig retired in 2024 after serving as our lead installer, technician, and stage curtain expert for over 36 years. Craig also took on an ownership role within the business and devoted his time to its success before his passing in 2026.

Drew Heller, Mark’s son, joined the ownership team of K&H in 2021 after 15 years of working in the company. He started as an installer and then moved to Project manager and Estimator. He currently serves as our Commercial Operations Director. Mark Heller Jr., Mark’s son, has also assisted the team with installations and estimating over the years. In 2026, Sandy’s two daughters Lauren Konkel and Alyssa Kuhns both joined the business with plans to continue the family legacy of providing quality custom window treatments for the Greater Lehigh Valley.
