Window Installation & Replacement
New windows cut drafts, reduce energy bills, and refresh your home's exterior — installed by the same crew that handles your roof and siding.
Windows, done properly.
Old or poorly fitted windows are one of the biggest sources of heat loss in a Midwest home. Top Notch Roofing & Exteriors installs energy-efficient replacement windows as part of a whole-exterior approach — so your new windows integrate perfectly with your siding, trim, and flashing rather than being bolted in as an afterthought. We handle standard double-hung windows through custom sizes for architectural openings.
What's included
- Free in-home estimate with energy-efficiency breakdown
- Removal and disposal of existing windows and frames
- Flashing tape and foam insulation on every rough opening
- Double- or triple-pane Low-E argon-filled glass
- Vinyl, fiberglass, or aluminum-clad frame options
- Interior and exterior trim work and caulking
- Haul-away of all packaging and old windows
- Manufacturer warranty plus our workmanship guarantee
From assessment to sign-off.
- 01
Measure
We measure every opening precisely. Custom-order windows take 2–4 weeks; in-stock sizes can install sooner.
- 02
Estimate
Written quote per window and per room, so you can phase the project if needed.
- 03
Order
We order direct from the manufacturer and track delivery. Your install is scheduled after windows arrive and are inspected.
- 04
Install
One window at a time — the opening is never left exposed. Flashing, foam, and trim finished before moving to the next.
- 05
Completion
Every window opened, closed, and locked before we leave. Interior trim touched up. All packaging removed.
Honest ranges. Firm quotes in writing.
Window pricing is highly dependent on size, style, and quantity. We measure in person before quoting. Multi-window projects receive better per-unit pricing.

|---|---|---|
| Standard double-hung window (installed) | $400 – $900 | Per window, including removal and trim |
| Whole-home window replacement (average home, 12–18 windows) | $6,000 – $15,000 | Volume pricing applies |
| Picture, bay, or custom-size windows | $800 – $2,500+ | Per unit, depending on size and frame type |
