Windows and baths built for the Island City
Wilmington earned its nickname, the Island City, from the island that splits the Kankakee River right at the edge of downtown. The original 1926 alignment of Route 66 runs through town, and the Gemini Giant now stands at South Island Park. Homes here tell that long story: 1890s and early-1900s houses near the historic downtown, brick bungalows and mid-century ranches on generous lots, and newer builds in subdivisions like Shadow Lakes. Old or new, these are houses people keep for the long haul.
Excel serves Wilmington from our headquarters in Tinley Park, about 30 miles northeast, covering the 60481 area as part of our Chicagoland service area. We've built windows, doors, siding, and baths since 1982 — decades of doing it once and doing it right. Replacement windows from Soft-Lite, ProVia, Sierra Pacific, and Pella suit both a downtown bungalow and a Shadow Lakes ranch. Add ProVia entry doors, CertainTeed and LP SmartSide siding, and Excel Shower & Bath remodels, and you have the full line — free in-home consultation, the same crews job after job, backed by our 5-year labor warranty.

Wilmington — common questions
Reviewed August 2026
Does Excel really serve Wilmington?
Yes — Wilmington is part of our Chicagoland service area. We're headquartered in Tinley Park, and we schedule free in-home consultations across the southwest suburbs, including Wilmington. One call confirms your date.
Who actually does the installation?
The same installation crews, job after job — not a rotating cast off a day-labor board. They know our products and our standards, and our 5-year labor warranty stands behind their work.
How much will my project cost?
It depends on the product and the size of the job, so we don't quote blind. The in-home consultation is free: we measure, show you the options, and leave a clear written proposal — no pressure. Financing is available; ask about options.
Do you serve Wilmington and the 60481 area?
Yes. Excel covers Wilmington and the 60481 ZIP from our Tinley Park headquarters, about 30 miles northeast, as part of our Chicagoland service area. We offer free in-home consultations for replacement windows, doors, siding, and bath remodels. You pick a time, we measure, and you get a clear written quote with no obligation.
What windows work best for older homes near downtown Wilmington?
Many houses near the historic downtown date to the 1890s and early 1900s, so replacement windows need to fit odd, older openings. We custom-measure Soft-Lite, ProVia, Sierra Pacific, and Pella windows to match. They cut drafts and run easier than the originals, while keeping the look right for a bungalow or a century-old two-story.
Can you remodel a bathroom in a Wilmington ranch or bungalow?
Yes. Excel Shower & Bath fits tub-to-shower conversions and full bath remodels into ranches, bungalows, and newer subdivision homes alike. We use Onyx Collection and Bath Concepts solid-surface walls with Moen fixtures — no tile grout to scrub, no liners over old surfaces. Most installs wrap in days, backed by our 5-year labor warranty. Free in-home consultation to start.
