Why Choose Dilworth?

Jerry Dilworth founded Dilworth Windows & Doors over 25 years ago and still operates it. Based on our need to put quality first, we are an "Employee Only" business (including our installers – no subcontractors). Over 97% of our new customers are referred by past customers.

Dilworth is a Window & Door replacement company. We specialize in offering the highest quality products available and combine that with unparalleled installation techniques by a trained & highly skilled installation team. We will also pre-paint or pre-stain your interior trim in any color! Famous for our service-after-the-sale, caring for our customers is what we are all about.

Our showroom, offices & warehouse have been located on 223 N Cass Avenue, in Westmont, for over 25 years. We serve all of the Chicagoland Suburbs.

Our showroom is open Monday-Thursday 10-5, Friday 10-3. Evenings and Weekends are available by appointment.

With over 500 referrals, we at Dilworth have a reputation you can trust. We work with only the most trusted brands and our installations are performed by our employees; they are not subcontracted out. We have a lifetime transferrable product and installation warranties and provide service long after the sale and installation.

We invite you to experience the Dilworth difference.

At Dilworth, the foundation of everything we do for you is built on caring.  Our philosophy is understanding your specific window & door needs and offering solutions in how to solve your problems.  From your interior & exterior design needs to specialized techniques for your installation type, Dilworth is concerned with your best interests from start to finish.  We refuse to utilize industry standard sales pressure techniques and offer a TRUE lifetime product & installation warranty.

Our caring attitude extends through our installation process.  Our installers are skilled, conscientious and detail oriented… because they are actual EMPLOYEES (not subcontractors) and an integral part of the Dilworth team.  They are trained, experienced professionals.

Subcontractors are paid by the window or door, thus their goal is to install as many as they can in a day. We pay our Dilworth employed installers hourly, so they focus on the quality of work they do, not the amount of work they can get done.

If it’s not already clear, we are a window and door company that is obsessed with doing everything right – even things that a homeowner typically won’t notice.  We never cut corners, never accept marginal work and insist that our team be neat, polite & clean; No loud radios, inappropriate language, etc., it’s just who we are.

Simply put, we do your project right the first time. Then we back it up with a TRUE Lifetime Installation Warranty on window & door replacement in Downers Grove, Darien, Naperville & Surrounding Areas.

Our Promise To You...

We use only superior and innovative products, never cut corners, prohibit sales pressure, and guarantee a fair price.

Why? Because We CARE.

If we sound like the kind of window & door company you would like to work with, then we ask you to contact us for a free, no-pressure consultation.   We would enjoy discussing your project with you.

Sincerely,

Jerry Dilworth
