Two Kinds of Lenexa Homes, Two Different Window Problems
Half of Lenexa’s homes were built before 1992 and half after, and each half has its own window problems.
North of K-10: original windows, 30 to 50 years in
Century Estates, Whispering Hills, Manchester Park, and the split-levels near Old Town went up in the 1970s and 1980s. If you still have the original windows, you likely see:
- Frames that sweat and frost up in January
- Haze between the panes you can’t wipe off
- Soft sills and sashes that won’t stay up
South of K-10 and out toward K-7: builder windows at their limit
About 4 in 10 Lenexa homes were built after 2000, many with builder-grade vinyl replacement windows now 15 to 25 years old:
- Rattling sashes and south or west rooms that stay hot
- The first foggy units on the sunniest side
Not sure which group you’re in? We’ll tell you at the consultation.
We recently had a sliding patio door, 2 exterior doors and our bay window replaced. Luke, Chris and Rosie did a great job on the work that was done. They kept me informed on progress and issues as they arose. And the finished products look great. I would definitely work with Energy Pro again.

I had a great experience with Energy Pro for the installation of my doors and windows. The complete the installation in a timely manner without compromising quality. I’m especially impressed with the warranty they offer. It’s clear the stand behind their work.

What Lenexa Weather Does to Tired Windows
Our weather is hard on windows, and the last two years proved it.
- Hail: The April 26, 2026 storm brought a severe thunderstorm warning and hail across Lenexa. Hail can break a seal that fogs weeks later.
- Heavy rain: In July 2025, Lenexa logged the county’s highest rain total at 87th Lane over Mill Creek. Poor flashing lets that water rot hidden framing.
- Heat and cold: The DOE says windows drive 25% to 30% of home heating and cooling energy use, so drafty ones keep your Evergy bill high.
Storm damage? Call your insurer first, and we’ll document what we see.
Replacement Window Options for Lenexa Homes
We carry several brands, so we fit the window to your house and budget.
Brands We Install
- Heritage by Joyce: Our most requested vinyl window, with fusion-welded, foam-filled frames and a magnetic seal that closes like a refrigerator door. Joyce rates its composite reinforcement for winds over 200 mph, and both sashes tilt in for easy cleaning.
- Vueline by Joyce: Another Joyce line built in Ohio, and a good one to compare side by side with Heritage. We’ll walk you through the differences in frame, glass and price for your home.
- Super Signature Series: Exclusive to Energy Pro, with MaxGuard 12 Thermal Glass and FiberCore reinforcement at the meeting rail, where a window takes the most stress in high wind. It’s designed to hold up to Kansas City’s weather swings.
- V Class by Sunrise: Premium vinyl from Sunrise with Low-E glass and multiple-pane options. It comes in a wide range of styles, from double-hung and casement to custom shapes.
- Marvin and Pella: For homeowners who already have a brand in mind or want fiberglass or wood options. A strong fit for homes with stained wood trim or a design that calls for a specific look.
Styles that Suit Lenexa Floor Plans
- Double-hung: Standard for most two-story and ranch homes; tilts in for easy cleaning.
- Single-hung vs. double-hung: Single-hung costs less; double-hung cleans easier and vents from the top.
- Sliders: Split-level lower rooms and wide openings.
- Casement: Over the kitchen sink, with a tight seal when closed.
- Picture, bay, and bow: Backyard-facing family rooms.
- Egress: Finished basements.
- Laminated glass: Quieter rooms near I-435 or K-10.

Energy-Efficient Windows Rated for Our Climate Zone
Lenexa sits in ENERGY STAR’s North-Central zone, where Version 7.0 requires a U-factor of 0.25 or lower and a solar heat gain coefficient of 0.40 or lower. Every window we install meets that standard.
Here is what does the work:
- Low-E glass reflects summer heat and holds winter heat
- Argon gas slows heat through the glass
- Insulated frames block cold through the vinyl
- Careful installation with foam, sealant, and flashing, so the opening doesn’t leak
Savings depend on your current windows, which way they face, and your HVAC, so we give you realistic numbers for energy-efficient windows after we see your home.
Window Replacement Cost in Lenexa
Our window replacement cost runs about $700 per opening installed for a high-efficiency vinyl window. Custom colors, wood grain interiors, and full-frame installs bring it to $1,200 to $1,400 per opening. A typical home of 10 to 15 windows often lands between $7,000 and $18,000. Your number depends on:
- Number and size of windows
- Brand, frame, and glass package
- Pocket install vs. full-frame (new construction) install
- Custom colors and finishes, like wood grain interiors or painted exteriors
- Bays, bows, and any rot repair
For the full breakdown, read our guide to the average cost of window replacement in Kansas City.
Why New Windows Cost More at Some Companies
Quotes from window companies in Lenexa can differ by more than double for the same windows, often because of national-brand markups and “sign today” pricing. Ask each one to itemize product, labor and warranty so you see what your new windows cost, not what the pitch costs.
Only the glass is foggy? If the frame still works and seals well, replacing just the window glass often runs $500 to $700 for a typical-size pane. We’ll tell you when that’s the smarter fix.
Ways to lower your cost
- Pocket install when frames are solid: Fitting the new window inside your existing frame can save $150 to $300 per window.
- Replace them together: Whole-home projects usually earn a 10% to 20% multi-window discount.
- Current offer: 10% off windows (not combined with other offers)
- Financing: Up to $75,000 through Wells Fargo and GreenSky, with approved credit
- Lenexa Exterior Grant Program: Homes built in or before 1977 and appraised at $366,000 or less may get 50% back, up to $5,000, on exterior work including windows. Prequalify before work starts; the next round opens in early 2027.
- Evergy rebates: Ask us about current Evergy rebates for insulation and air sealing around your window openings.
- Federal tax credit: The 25C window credit ended December 31, 2025.

How Your Lenexa Window Project Works
Our window installation process takes four steps, with no guesswork.
STEP 1
In-Home Consultation

STEP 2
Measure & Manufacture
You choose your brand, style, glass, and color, and you're welcome to visit our showroom. We take precise measurements, help with any HOA paperwork, and send your order to our manufacturing team. Custom windows usually take a few weeks to build.
STEP 3
Install & Cleanup
Once your windows are ready, our in-house crew with over 125 years of combined experience installs them, and most Lenexa homes are done in one to two days. We pull any city permit needed and haul away the old windows.
STEP 4
Get Peace of Mind
Your new windows are built to handle Lenexa's hail, summer heat, and January cold. We register your manufacturer warranty, and our 10-year service warranty covers the installation.

Lenexa Replacement Windows FAQs
Window replacement cost with Energy Pro runs about $700 per opening installed, up to $1,200 to $1,400 for custom colors, finishes, or full-frame installs. What new windows cost for your home depends on the brand, size, glass package, and any rot repair. A free in-home quote gives you an exact, itemized number.
A permit is required when an opening changes size or framing is involved, and the city usually reviews it in five business days. For same-size swaps, we confirm with the City of Lenexa before we start. Either way, we handle the paperwork for you.
The federal 25C tax credit for windows ended on December 31, 2025. Lenexa’s Exterior Grant Program can reimburse 50% of qualifying exterior work, up to $5,000, for homes built in or before 1977 and appraised at $366,000 or less. The next application round opens in early 2027.
Usually, yes. Windows from the early 1990s and before often have failed seals, worn balances, and glass that falls well short of today’s ENERGY STAR rules for our zone. New energy-efficient windows cut drafts and take pressure off your furnace and AC.
Spring and fall book up fastest, so late fall and winter often mean shorter waits. We install year-round and keep your home protected during the work. The best time is before a small seal or rot problem becomes a bigger one.
Most windows take 30 to 60 minutes each, and most Lenexa homes are finished in one to two days. Custom windows take a few weeks to build after you order, so plan for several weeks from quote to install day.
Replacing them together usually lowers the per-window cost and gives you matching color and glass throughout. If budget is tight, start with the failed or foggy units and the sunniest walls. We can phase the project so it still looks uniform.
Many policies cover sudden storm damage like hail, but coverage varies. Call your insurer before scheduling work, and we can document the damage for your claim. Note that work paid by insurance can’t also be reimbursed through Lenexa’s Exterior Grant.
Confirm the window contractors hold a Johnson County contractor’s license and a Lenexa business license, since the city requires both. Ask each window company for an itemized quote that separates product, labor, and warranty. Skip any price that expires when the salesperson leaves, and compare at least two quotes before you buy replacement windows in Lenexa.
