Our Reputation. The Result of Years of Superior Service.
For decades, QDH has been providing its solid customer base with doors and frames and an impressive inventory of commercial door hardware. With more than 25 years of experience, QDH has earned an industry wide reputation for customer service that has made QDH a trusted and recognized commercial door hardware industry resource.
Our 25,000 square foot New York facility is stocked with door hardware items from the most popular brands, as well as those difficult-to-find hardware items, that few other companies carry.

Simple... Not Easy
Customer satisfaction- it seems like such a simple goal. But it actually takes hard work and dedication to meet that goal for each and every one of our customers. This simple concept is the reason Quality Door & Hardware first opened its doors back in the 80’s. Our founder, Jeffrey Dinardo Sr., saw an opening in the market for a hands-on, customer-focused organization that would treat each of its customers to professional, quality service. Jeff  recognized the importance of providing businesses with a commercial door and hardware company they could trust and rely on. Now, tens of thousands of customers later, Quality Door & Hardware’s reputation continues to grow with every satisfied customer.

Our Values
It comes down to values. At QDH, we truly value you, the customer. We place you first, in every situation. Whether you need advice, guidance, support...whatever it takes to ensure that you end up with the product you need, when you need it. We treat all of our customers with caring professionalism and a sincere interest in your success.

The Quality Difference
We refer to these value added services as "The Quality Difference" - a combination of customer service, after-sale support, and as much extra value as we can possibly provide. Our goal is to ensure that you return to QDH for all your commercial hardware needs.

QDH is pleased to have the opportunity to earn your business by having you call or visiting us at our web site. We hope that you like what you see, and that you will join our thousands of other satisfied customers by making QDH your industry resource for commercial door hardware. We invite you to experience the difference that "Quality" can make in your business.   Thank you.
