Window Replacement

Replace old, drafty windows with energy-efficient, beautiful new units

A window replacement project usually starts with a specific frustration — a drafty window, a failed seal that fogs in the winter, a sash that won't stay open — but most homeowners come out the other side realizing how much older windows were quietly stealing from them: comfort, energy savings, sound isolation, and curb appeal. Replacing them restores all of it in one project.

Dynasty Restoration handles window replacement across the full quality spectrum: premium vinyl, fiberglass, and clad-wood windows from Pella, Andersen, Marvin, and leading mid-market vinyl manufacturers. Every project includes precise measurement, a transparent written quote with NFRC performance data, and professional installation with proper flashing and insulation.

What's Included in a Window Replacement

Pre-Install Measure

Every opening measured to 1/16" for proper fit. Ordering from a bad measure is the #1 cause of window project delays.

Proper Flashing

Head, jamb, and sill flashing installed in the correct sequence so water drains out of the wall, not into it.

Insulation & Air Sealing

Low-expansion foam between frame and rough opening; backer rod and sealant at interior and exterior perimeters.

Interior & Exterior Trim

All finished trim installed and caulked so the window is ready for paint — no construction gaps visible.

Written Workmanship Warranty

Every install backed by a written labor warranty on top of the manufacturer's window warranty.

Debris Removal

Old windows, packaging, and debris removed daily. Driveway and walks swept with a magnet to catch fasteners.

Picking the Right Window for Your Home

Window selection comes down to three decisions: frame material (vinyl, fiberglass, or clad wood), operation style (double-hung, casement, sliding, etc.), and glass package (double vs. triple pane, Low-E coating, argon or krypton fill). We walk through each with you, explain the tradeoffs in plain English, and quote two or three options at different price points so you can see the value at each tier. No hard sell, no mystery pricing.

Frequently Asked Questions About Window Replacement

How much does window replacement cost in Chicagoland?
Quality mid-market vinyl replacement windows typically run $700–$1,200 per opening installed, depending on size and operation style. Clad-wood and premium fiberglass lines are $1,200–$2,200+ per opening. Whole-house projects commonly bundle at a better per-opening rate.
How long does the installation take?
A typical 2-person crew installs 8–12 pocket replacement windows per day. Whole-house projects usually complete in 2–4 working days depending on size and window style.
Do new windows really save on energy bills?
Yes — especially when replacing single-pane, aluminum-framed, or pre-2000 double-pane windows. The comfort improvement (no cold drafts, no hot afternoon west sides) is immediate; energy bill savings typically show up in the first winter and summer.
Will I need to repaint interior trim after install?
For pocket replacements, usually not — we preserve and reuse existing interior trim. For full-frame replacements, new interior trim is installed in primed condition; paint is a simple follow-up.
