How Much Does Vinyl Window Replacement Cost in Houston?
A single-hung vinyl replacement window from us costs between $775 and $2,500 across the Houston area, and that price includes installation. Where your project lands in that range depends on the window series you choose, the style and size of each opening, the glass package, and the condition of the openings once the old windows come out.
The Window Source of Houston publishes these ranges so you can plan your budget before anyone visits your home. Your free in-home consultation turns them into an exact price for your windows.
Replacement Window Prices by Series
The TWS 3000, 6000 and 9000 Series are The Window Source’s own vinyl window lines, carried by Window Source locations across the country. Each series steps up from the one before it in options and performance, and the price per window steps up with it. These are our 2026 prices for one single-hung window in each series, and every one includes installation.

What Changes the Cost of Replacement Windows
Two homes with the same number of windows can get very different quotes. These are the things that move the price, and we’ll go through each one with you at your consultation.
Window style
The prices on this page are for a single-hung window, which sits with sliders and picture windows among the least expensive styles to replace. Casements, bay and bow windows, and custom shapes take more material and more labor to build and install, so they cost more.
Size and number of windows
A larger opening needs more glass and more frame, so it costs more per window. The number of windows you replace sets the size of the whole project.
Glass package
Extra Low-E coatings, triple-pane glass and impact-rated glass each add to the price of a window. In Houston’s heat, better glass also means lower cooling bills for as long as you own the home.
Frame color and finish
Standard white frames are the least expensive. Darker exterior colors, woodgrain interiors and grids between the glass all add to the cost of each window.
Condition of the openings
Rotted framing, old water damage or an opening that’s out of square has to be fixed before the new window goes in. That repair adds labor and materials to the openings that need it.
At The Window Source of Houston, every price includes professional installation with our Leak Shield method at no additional cost. Every installation is backed by the lifetime, transferable Leak Shield Guarantee, which covers the seal, the flashing and the fit for as long as you or the next owner live in the home.
Estimate Your Project
The estimate multiplies the single-hung vinyl price range for the series you pick by the number of windows. It includes installation and leaves out repairs to damaged openings, which we can only price once we’ve seen them.

“I got several quotes, and Jairo was the only one who brought samples and took the time to give us a demonstration. The office stayed in communication with me every step of the way… Edwin’s installation team worked quickly and professionally.”
“Replacing my parents’ original builder-grade windows in their 25+ year old home was one of the best investments they’ve made… They’ve already noticed lower electric bills, less outside noise, and a cooler, more comfortable home that’s much easier to keep at a consistent temperature.”
Questions About Window Replacement Pricing
Why do you show a price range for each window?
Every home is different, and one advertised price would be wrong for most of them. Each range on this page is for one single-hung vinyl window in that series, installed. Size and glass choices move the price within the range, other styles such as casements and bay windows cost more, and your free in-home consultation narrows it all to an exact price for your windows.
Is the in-home estimate free?
Yes. The consultation and the detailed estimate are both free, and there’s no pressure and no obligation to go ahead with the project.
Does the price include installation?
Yes. Every range on this page includes professional installation and our Leak Shield installation method, which comes at no additional cost and is backed by the lifetime, transferable Leak Shield Guarantee.
Do I have to replace all my windows at once?
No. You can start with the windows that need it most and replace the rest later. If you plan to work in phases, tell us at the consultation so we can keep the series and colors consistent from room to room.
Do you offer financing?
Yes. The Window Source of Houston offers several payment plans, so you can spread the cost of a larger project over time. The current options are on our financing page.
