Siding & Windows Group

What Siding & Windows Group does

Siding & Windows Group is a privately held, founder-owned exterior remodeling contractor headquartered in Glenview, Illinois, operating under the legal name Siding & Windows Group LTD. Founded in 1984 by current Owner & Operator Greg Bednarski, the company specializes in full building-envelope installation services — siding, replacement windows, entry and patio doors, residential and commercial roofing, composite and wood decking, and insulation — for residential and multifamily customers across the Chicago metropolitan area. It is staffed by 101-250 employees and runs three physical offices in Glenview, Chicago, and Wheaton, with a direct field-sales motion (in-home consultations, phone, and web quote requests) and no dealer or retail intermediary.

The core technology is skilled installation rather than software. The company holds tier-one manufacturer credentials, most notably James Hardie Elite Alliance Contractor status, alongside GAF, Owens Corning, Malarkey Emerald Pro, Marvin Authorized Replacement, Pella Certified, TimberTech Platinum Pro, ProVia Certified Professional, and Vinyl Siding Institute certification. Products are sourced from James Hardie, Marvin, Pella, Alside, Simonton, ProVia, Versetta Stone (Boral), Longboard, TruExterior, Mastic (Ply Gem), GAF, Malarkey, McElroy Metal, DaVinci, TimberTech, Azek, Progressive Foam, and InSoFast. Pre-sales tools include the Renoworks design center, James Hardie and Alside color visualizers, and a TimberTech deck visualizer; there is no proprietary software platform, no API, and no AI/ML layer disclosed.

Revenue is generated entirely from professional installation services priced per project. Publicly disclosed pricing benchmarks include $14-$20 per square foot for James Hardie siding installation with most full projects ranging $25K-$60K+, and $311-$507 per unit for fiberglass window installation. Customer financing is offered through Synchrony, including 0% for 18 months, to support larger project tickets. Customer segments are predominantly residential homeowners (including historic-home restoration), with a secondary multifamily and commercial property-owner vertical, served through 500+ five-star reviews, GuildQuality Guild Master distinction, BBB accreditation, and a formal customer referral program.
