QUESTIONS PEOPLE ASK US
How long does installation take?+
Most installations are completed in a single day. We show up on time, do the work, and clean up after ourselves.
Do you subcontract the installation?+
Never. Every installation is done by our in-house crew — the same guys who've been doing this for decades.
How much does a security storm door cost?+
Pricing depends on the style, size, and features you choose. We offer 50+ options at different price points. Request a free estimate — no obligation, no pressure.
What areas do you serve?+
We serve all of Chicagoland and Northwest Indiana. Based in Cicero, IL — Oak Park, Berwyn, Elmwood Park, La Grange, Riverside, and everywhere in between.
How does the process work?+
Easy — our representatives will come to you at no additional charge. We'll measure your door frames, walk through styles and color options in person, and give you a transparent quote on the spot. No salesman pressure, no surprises.
Will a storm door help with drafts and energy bills?+
Yes. Our doors use magnetic weatherstripping and adjustable thresholds to create an air-tight seal. Customers regularly tell us their drafts are gone and their heating bills dropped.
What's the difference between steel and aluminum storm doors?+
Steel is significantly stronger and more durable. Our 22-gauge steel doors are up to 60% stronger than standard aluminum options.
How long does it take to get my door after ordering?+
Lead times vary based on style and customization, but most orders are ready within 3-6 weeks. We'll give you a clear timeline with your estimate.
