Why Do Our First-Time Customers Become
Lifelong Customers…

Because We Have True Passion For Quality, Value And Genuinely Care About The Outcome Of Your Project.

By Jerry Dilworth, Owner:

Thank you for taking the time to visit our website and read this letter.

I’ve been in the home improvement business since 1980. Everyone says that I am a perfectionist and I carry that into our product choices and installation techniques. When I started doing jobs for people in the Western Suburbs, I learned what was important to them. In addition to the quality of the work I did, it was the clean-up and respect I showed for their home and personal property. I accomplished this by taking as much care as possible to service their personal needs both inside and outside their home with pets, furniture, flooring and protecting flower beds & bushes, etc. Whatever it is that we do, it is always done the best.

I never set out to be the biggest company; my goal was and is to be the best. Without sounding like we are bragging, over 97% of our business is from referrals. I understood early that if on every job we impress the customer beyond their expectations, we would never be without work. Thinking about all the benefits of doing business with Dilworth, one of the biggest things that stands out is making sure our customers have a good experience before, during and after the sale. It is our philosophy that in taking care of people, people take care of you. When I opened Dilworth Windows & Doors in Westmont in 1993, I brought that passion to this company—and I made sure to build a team that has that same goal.

At Dilworth, we have ONE priority: Taking care of our customers. Our unwavering mission is to provide the best possible door and window replacement in Naperville, Downers Grove, and all of the surrounding areas. That means installing only industry-leading products. That means having our own crew of talented, experienced, and professionally-trained employed installers, instead of outsourcing the labor to unreliable subcontractors. That means providing honest, fair pricing and a Lifetime Installation Warranty.

Unlike many contractors, I didn’t “fall into” home improvement—it is my passion. And it’s the same for everyone on the Dilworth team. So if you’re looking for a window and door company near Naperville, Darien and the surrounding areas, look no further. We would enjoy discussing your project with you.

Thank you for your time.
