Markham's bungalows, Cape Cods, and ranches
Markham sits in Cook County's south suburbs, ringed by Harvey, Posen, Midlothian, and Hazel Crest. Its streets tell a clear story: Croissant Park went up in the mid-1930s, and the town filled in as a bedroom community after the war. You see it in the housing — classic brick bungalows, Cape Cods, split-levels, and ranch homes on generous lots, in pockets like Canterbury Gardens, Southtown Manor, and Country Aire Estates. On the edge of town sits the Gensburg-Markham Prairie, a National Natural Landmark and one of Illinois' last stands of native grassland.
Excel is headquartered in Tinley Park at 8049 185th St, a short drive southwest of Markham, and we've been at this since 1982. We bring free in-home consultations to town and take each house on its own terms. Older bungalows and Cape Cods often need windows that seal out drafts and cut the winter heating bill. Ranches and split-levels are good candidates for new siding or a fresh entry door. And a dated bathroom can become a safe, low-maintenance walk-in shower. Same crews, job after job.

Markham — common questions
Reviewed August 2026
Does Excel really serve Markham?
Yes — Markham is part of our Chicagoland service area. We're headquartered in Tinley Park, and we schedule free in-home consultations across the south suburbs, including Markham. 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.
Does Excel work in Markham?
Yes. Excel is based in Tinley Park, a short drive southwest, and Markham (ZIP 60428) is part of our south-suburban service area. We come to you for a free in-home consultation, measure the actual openings, and give you a written price. Windows, doors, bath, and siding are all handled by the same crews we send job after job.
What windows make sense for a Markham bungalow?
Older brick bungalows and Cape Cods around Markham were built before modern insulated glass, so drafts and high heating bills are common. Our main line is Soft-Lite, with ProVia, Sierra Pacific, and Pella also available. We measure each opening, since original 1930s and postwar frames rarely match today's stock sizes, and install to seal out the cold.
Can you remodel a small older bathroom?
Yes. Many Markham homes have one original, tight bathroom, and that's exactly what Excel Shower & Bath handles. We replace a worn tub or shower with a low-maintenance Onyx or acrylic solid-surface system and Moen fixtures — no tile lines to scrub and no liners over old surfaces. Most installs wrap in days, and everything carries our labor warranty.
