Frequently Asked Questions
Window & Door FAQs
How much does it cost to replace windows in the South Chicago suburbs?
Window replacement typically ranges $600–$1,500 per window depending on size, material, style, and installation needs. Larger custom units or bay/bow windows cost more. We provide free, no-pressure quotes so you always know your exact price before we begin.
Do you offer free estimates or quotes?
Yes. All quotes are 100% free, include measurements, product recommendations, and a written price guarantee.
What affects the price of new windows the most?
The biggest factors include window size, frame material (vinyl, fiberglass, wood), glass options, and the installation method. Homes with older or original windows may also require minor carpentry work.
Do you offer financing or monthly payment plans?
Yes. We offer flexible financing options to make your project affordable—often with low-monthly-payment plans.
Will new windows help lower my utility bills?
Absolutely. New ENERGY STAR–rated windows significantly reduce drafts and heat loss, especially in Chicago winters. Most customers see a noticeable drop in heating and cooling costs.
How long does window installation take?
Most homes can be completed in one day, depending on how many windows you’re replacing. Larger or more complex projects (bay/bow windows) may take slightly longer. The timeline will be covered during the purchase and planning process.
Can you install windows and doors during winter?
Yes. Window replacement is done year-round, even in cold weather. We install one window at a time to keep your home comfortable.
Do you handle trim work, caulking, and cleanup?
Yes. We handle interior and exterior trim, insulation, caulking, cleanup, and disposal of your old windows and doors. Your home is left clean when we’re finished.
Do I need to be home during the installation?
We only require someone home at the start and finish of the project. We work cleanly and efficiently throughout the day.
Can you replace just the glass instead of the whole window?
No, in most cases, if you have drafty or aging windows, a full replacement is the best long-term solution.
What types of windows do you install?
We install all popular styles, including double-hung, casement, sliders, bay, bow, picture, awning, and specialty shapes. We also install both replacement and new-construction windows depending on your project.
What window material is best for Chicago’s climate?
Vinyl and fiberglass windows are typically the best performers for Midwest temperature swings. They offer excellent insulation, durability, and low maintenance.
Are your windows ENERGY STAR rated for our region?
Yes. All windows we install meet or exceed the latest ENERGY STAR requirements for the Northern Climate zone, which includes Illinois.
Do new windows reduce drafts and outside noise?
Yes. Modern windows are designed to seal tightly and reduce both air leakage and sound transfer, especially when using double- or triple-pane glass.
What’s the difference between double-pane and triple-pane windows?
Triple-pane windows add an extra layer of insulation and gas fill. They offer better energy efficiency and noise reduction, especially helpful in busy neighborhoods or near main roads.
Do you have before-and-after project photos?
Yes. We have a full gallery (https://www.welshwindowsplus.com/resources/gallery)featuring homes throughout the South and Southwest Chicago suburbs, including Tinley Park, Orland Park, Joliet, Oak Lawn, Frankfort, Alsip, and more.
Do you serve my area?
We serve all of the South Chicago suburbs including Tinley Park, Orland Park, Frankfort, Mokena, Joliet, New Lenox, Oak Lawn, Alsip, Palos Heights, Palos Park, and surrounding communities.
Are your installers certified or factory-trained?
Yes. Our in-house installers are fully trained, certified, and experienced in proper Midwest installation methods.
Do you install new-construction windows for additions or remodels?
Yes. We work with homeowners, builders, and contractors to supply and install new-construction windows for remodels or new builds.
What types of entry doors do you install?
We install fiberglass, steel, and wood entry doors, along with sidelights, transoms, and sliding or hinged patio doors.
What’s the difference between steel, fiberglass, and wood entry doors?
• Fiberglass: Best mix of durability, insulation, and low maintenance
• Steel: Very strong and cost-effective
• Wood: Beautiful and customizable, but requires more maintenance
Will a new entry door help with drafts?
Yes. Modern doors are insulated and designed with tight weatherstripping to eliminate air leaks around your entryway.
Can I customize the look of my door?
Yes. Choose from endless colors, glass designs, hardware, finishes, and security upgrades—including multi-point locks and smart options.
What warranties come with new windows?
We offer industry-leading manufacturer warranties plus our own workmanship guarantee. This covers both the product and the installation.
How long do modern windows last?
Most high-quality windows last 25–30+ years with minimal maintenance.
How do I know when it’s time to replace my windows or door?
You may notice:
• Drafts or cold spots around windows/doors
• Fogging between glass panes
• Higher utility bills
• Difficulty opening or closing windows
• Rotting wood or visible damage
• Outdated or original windows from 20+ years ago
If any of these sound familiar, it’s likely time for an upgrade.
Will new windows increase my home’s value?
Yes. Window replacement is one of the highest-ROI home improvements, improving both curb appeal and energy efficiency.
