Energy-efficient replacement windows from Simonton, Wincore, and the manufacturers we've trusted for three decades. Custom-measured, professionally installed, and backed by a lifetime workmanship warranty.
We've installed thousands of windows across Knox County since 1996. Same family-owned name. Same warranty. When something needs attention five years from now, you call the same number.
We don't push a single brand or style. We help you choose what actually fits your home's architecture, your light needs, and your budget — and then we install it like it's our own house.

The Knoxville classic. Both sashes open for ventilation, tilt in for easy cleaning. Best all-around choice for most homes.

Bottom sash slides up, top stays fixed. Slightly more energy-efficient and budget-friendly than double-hung.

Crank-out style for maximum airflow and unobstructed views. The best seal of any operable window type.

Architectural focal point. Adds depth, light, and seating space — and serious curb appeal.

Fixed, oversized panes that frame the view. Best for energy efficiency since there's no operable seal.

Garden windows extend outward for herbs and plants. Sliders glide horizontally — perfect over kitchen sinks.
Every window we install meets or exceeds Energy Star standards for the South-Central climate zone. For most Knoxville homes replacing 20+ year old windows, we typically see heating and cooling bills drop 15-25% the first year. We'll show you the U-factor, SHGC, and air infiltration ratings on every window we quote.
The manufacturer warrants the window. We warrant the installation — for as long as you own the home. If a sash sticks five years from now, you call us, we come fix it. No hourly rate, no service fee, no argument.
We're authorized installers for Simonton, Wincore, and several other premium manufacturers. We don't push one brand for kickbacks. We recommend what fits your home, your energy goals, and your budget. If you've gotten a quote from a one-brand company, we'll happily price the same job in two or three options so you can compare.
Most of the installers on your project are our own employees. For larger jobs that need additional skilled trades, we bring in vetted partners we've worked with for a long time — never day-labor or rotating crews. The same level of care from project one to project ten thousand.
Installed replacement window prices in Knoxville typically fall into these ranges:
These are ballpark figures. Your exact price depends on window size, frame material, glass package, and home access. We give you an itemized written quote good for 90 days — no pressure to decide on the spot.
We've refined this process across thousands of Knoxville homes. No high-pressure sales pitches. No "today only" pricing. Just a clear, predictable path from estimate to finished install.
A designer (not a commission salesperson) comes out, measures, brings samples, and listens to what you actually want. Usually within a week of your call.
Line-by-line pricing showing window models, glass packages, installation, disposal, and trim. Good for 90 days. No "sign tonight" pressure — ever.
Once you approve, we order the custom-sized windows. Typical lead time is 4–6 weeks. We schedule your install date when materials arrive — no guessing.
Our crew handles removal, install, trim, sealing, and cleanup. Most projects finish in 1–3 days. We don't leave until you're walking the house with us.
Most contractor sites hide pricing because they want to control the conversation. We'd rather you know the ballpark before we even meet.

Installed replacement window prices in Knoxville typically range from $500 to $1,200 for standard double-hung vinyl windows, and from $1,200 to $2,500 for larger or specialty windows like bay, bow, or custom-shaped openings.
Whole-house projects of 10–15 windows usually fall between $8,000 and $18,000 installed, depending on window style, frame material, and home access. We provide free in-home estimates with itemized written quotes — and the quote is good for 90 days, so there's no pressure to decide on the spot.
Most replacement window projects take 1–3 days depending on the number of windows. A typical 10-window home is completed in a single day by our crew.
The full timeline from "yes, let's do this" to finished install is usually 5–8 weeks, with most of that being lead time on the custom-sized windows from the manufacturer. We handle the entire process: removing old windows, installing the new units, finishing trim, and full cleanup before we leave.
We're authorized installers for Simonton, Wincore, and several other premium manufacturers. We deliberately don't push a single brand — different homes and budgets call for different windows.
All windows we install carry the manufacturer's warranty (typically lifetime on the frame and seal, with prorated glass coverage) plus our lifetime workmanship warranty. If a window we installed develops an issue years from now, you call us, we come fix it.
For most Knoxville homes with single-pane glass or 25+ year old windows, yes. Energy Star-rated replacement windows can reduce heating and cooling bills by 12–25% in our East Tennessee climate, where we run AC five months a year and heat for four.
Beyond the energy savings, replacement windows reduce outside noise, eliminate drafts, and add resale value. Most homeowners recoup 70–80% of the window investment at resale, according to Remodeling Magazine's annual Cost vs. Value report for the South region.
Yes. We offer several financing options including 0% promotional rates for qualified buyers, as well as longer-term installment plans. We'll go over financing options during your free in-home estimate so you can see actual monthly numbers alongside the project cost.
We don't pressure financing — many of our customers pay outright. But for whole-house projects in the $10,000+ range, financing can make the project happen this year instead of "someday."
Quality vinyl replacement windows installed correctly last 20–30 years. Wood and clad-wood windows can last 30+ years with proper maintenance. Fiberglass windows are the longest-lasting, often 40+ years.
The manufacturer warranties we work with cover most issues for the lifetime of the original homeowner, and many transfer to the next owner one time. Our workmanship warranty has no expiration — it covers our install for as long as you own the home.
Not for the whole project, but we ask that you (or someone) be home at the start so we can do a final walkthrough, confirm window placements, and review any last-minute questions. After that, you're welcome to go to work or run errands — our crew works independently and locks up if you leave.
We always do a walkthrough with you at the end so you can inspect each window before we close out the project.
We work throughout Knox County and the surrounding counties — including Fountain City, Halls, Powell, Karns, Farragut, West Knoxville, Sequoyah Hills, Bearden, North Knoxville, South Knoxville, East Knoxville, and the wider Loudon, Blount, Anderson, Sevier, Roane, Union, Jefferson, and Grainger counties.
If you're within an hour of our showroom on North Broadway, we can almost certainly help. Call (865) 689-0505 if you're not sure.
Most of our window customers eventually do siding, doors, or roofing with us too. Same crew, same warranty, one company to call.
