High-quality, energy-efficient windows in your home.
Our Window Services
Opal Exteriors provides two primary window services for Chicagoland homeowners. Both services use manufacturer-certified installation standards, premium window brands, and come backed by strong product and labor warranties. Note that we only install windows sourced through our trusted manufacturer partners — we do not install customer-supplied products.
Not sure which service you need? Window replacement (also called pocket or insert replacement) installs new window units into your existing frames — faster, less invasive, and more cost-effective when frames are structurally sound. Window installation (also called full-frame or new construction) removes the entire frame, trim, and flashing, making it the better choice for damaged frames, remodels, or new openings.
Window Replacement
The most common window service for Chicagoland homeowners. If your windows are aging, drafty, damaged, or simply outdated, replacement upgrades your home’s energy efficiency, comfort, noise reduction, and curb appeal in one project.

What is the difference between window replacement and window installation?
+
|
Window Replacement Also called pocket or insert replacement. The existing frame stays — only the window unit is replaced. Faster, less invasive, and more affordable. Best for: solid existing frames, aging windows, energy upgrades |
Window Installation Also called full-frame or new construction. The entire frame, trim, and flashing is removed. More involved but necessary for damaged frames or new openings. Best for: damaged frames, remodels, additions, new openings |
Not sure which applies to your home? Our team will assess your frames during a free consultation.
How long does a window replacement project take?
+
Most projects are completed in one to two days on-site. However the full timeline includes a manufacturing lead time of typically 4 to 10 weeks after your order is confirmed, depending on the brand and product specification.
|
1 – 5 Windows Half day – 1 day |
6 – 12 Windows 1 – 2 days |
12+ Windows 2 – 4 days |
Do new windows increase home value?
+
Yes. New windows are one of the highest-return exterior improvements a homeowner can make. Industry data consistently shows homeowners recoup 68–72% of window replacement costs at resale — and that’s before factoring in energy savings and improved comfort while you still live there.
|
Lower Energy Bills Modern Energy Star windows reduce heating and cooling costs year-round in Illinois’s demanding climate. |
Stronger Curb Appeal New windows immediately improve your home’s exterior appearance and first impression for buyers. |
|
Improved Comfort Eliminate drafts, reduce outside noise, and remove condensation issues for a more comfortable home. |
Higher Appraised Value Appraisers and buyers recognize updated windows as a quality upgrade that reflects in your home’s value. |
What window brands does Opal install?
+

|
Andersen America’s most trusted window brand. Known for Energy Star compliance, reliability, and a wide range of styles. |
Kolbe Premium wood and aluminum-clad windows built for custom design and architectural flexibility in high-end homes. |
ProVia High-performance vinyl and fiberglass windows engineered for superior insulation and Midwest weather resistance. |
Does Opal install customer-supplied windows?
+
No. Opal Exteriors only installs windows sourced through our trusted manufacturer partners. This ensures every product meets our certified installation standards and is fully covered by both the manufacturer product warranty and our 5-year workmanship warranty. Installing customer-supplied products would compromise our ability to stand behind the quality and longevity of your project.
