Windows Cost Factors in Illinois
Window replacement costs in Illinois depend on the number of windows, frame material, glass package, and installation complexity. Here are typical per-window ranges for Illinois homeowners:
- Vinyl double-hung (double-pane): $600 – $1,200 per window installed
- Fiberglass double-hung (double-pane): $900 – $1,800 per window installed
- Wood/clad double-hung (triple-pane): $1,200 – $2,500 per window installed
- Specialty windows (bay, bow, picture): $1,500 – $5,000+ depending on size and configuration
A typical Illinois home has 15-25 windows, making a whole-home replacement project range from $10,000 to $50,000+. Weatherguard recommends full-frame replacement over insert (pocket) replacement because it allows us to inspect and repair the rough opening, add proper insulation and flashing, and ensure the tightest possible air seal.
Comparing Windows Options
Choosing the right windows for your Illinois home involves evaluating frame materials, glass packages, and performance ratings. Here's how the key options compare:
Full-Frame vs. Insert Replacement: Full-frame replacement removes the entire window including the frame, allowing inspection of the rough opening, proper insulation, and new flashing. Insert replacement slides a new window into the existing frame, which is faster but sacrifices glass area and may hide underlying moisture damage. Weatherguard recommends full-frame for Illinois homes.
Double-Pane vs. Triple-Pane: Triple-pane windows offer 20-30% better insulation than double-pane and significantly reduce outside noise. In Illinois's climate with extreme cold, triple-pane windows dramatically reduce condensation and cold spots near windows. The upgrade typically costs $75-$150 more per window.
Vinyl vs. Fiberglass vs. Wood: Vinyl frames are the most affordable and lowest maintenance. Fiberglass offers superior strength and thermal performance with a paintable exterior. Wood provides the most classic aesthetic with the best insulating properties but requires periodic maintenance. Clad wood (wood interior, aluminum or fiberglass exterior) offers the best of both worlds.
Storm Damage and Windows in Illinois
Illinois's severe weather — including hail, high winds, heavy snow, and ice storms — can cause significant damage to your home's windows. When storm damage strikes, Weatherguard Construction provides rapid-response assessment and repair services throughout Illinois. Our experienced team documents all damage thoroughly, works directly with your insurance company, and advocates on your behalf to ensure your claim covers the full scope of necessary repairs.
We maintain emergency response capability year-round and can typically provide a damage assessment within 24-48 hours of a major storm event. Our goal is to restore your home to pre-storm condition quickly and professionally while making the insurance process as stress-free as possible.
Our Windows Process
Weatherguard follows a proven, systematic process for every windows project to ensure consistent quality and customer satisfaction:
- In-Home Consultation: A Weatherguard window specialist visits your home to evaluate existing windows, measure each opening, discuss frame materials and glass options, and provide a detailed written estimate.
- Factory Order: Your custom-sized windows are ordered directly from the manufacturer. Lead times are typically 4-8 weeks depending on the brand and specifications selected.
- Pre-Installation Inspection: Before installation day, our project manager confirms all measurements, reviews the installation plan, and coordinates access and timing with you.
- Old Window Removal: Our crew carefully removes the existing window and frame, then inspects the rough opening for any moisture damage, rot, or structural issues. Any problems are repaired before proceeding.
- Installation & Sealing: The new window is set, leveled, shimmed, and secured. We apply premium flashing tape, spray foam insulation, and backer rod with caulk to create an airtight, waterproof seal around every window.
- Interior & Exterior Trim: New interior casing and exterior trim are installed for a finished look. We can match your existing trim profile or upgrade to a new style.
- Final Testing & Walkthrough: Every window is tested for smooth operation, proper locking, and seal integrity. We demonstrate hardware features and maintenance procedures, then complete a final walkthrough.
