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.
