Residential window replacement in Tulsa
Windows that look right and work again
A window that fogs up between the panes, lets in a draft, or will not open is usually the reason to call. Sometimes it is only a few windows.
We look at every window with you, tell you which ones really need replacing, and fit the right window to each opening, so you never pay to replace a good one.

Vinyl replacement windows in Tulsa
Every window style, installed
We install every style, from double-hung to bay, bow and garden windows and custom shapes. Whatever you order, we install.
Window styles
Here is what each style is and when it fits. We bring samples and brochures so you can see them at your house.
-
Double-hung
Both sashes slide up and down, so you can open the top, the bottom, or both for airflow.
-
Single-hung
The bottom sash slides up while the top stays fixed. A simple, classic look.
-
Casement
Hinged on one side and opened outward, so the whole sash swings open to catch a breeze.
-
Awning
Hinged at the top and opened outward from the bottom. Often set above or below a larger window.
-
Gliding
A sash slides sideways instead of up and down. Good for wide openings where a crank or lift is awkward.
-
Picture
A fixed window that does not open, made for light and the view.
-
Bay
Three windows set at angles so the window pushes out from the wall, adding light, a view and a little floor space.
-
Bow
Four or more windows in a gentle curve, a softer, rounder version of a bay.
-
Garden
A small box window that projects out from the wall, with a sloped glass top and a deep shelf, made for plants and fresh herbs all year.
-
Specialty shapes
Arches, circles, angles and fully custom windows for openings that are not rectangles, like an arched window over a door.
Frame materials
What the frame is made of decides how it holds up and what it needs. Here is what we install.
-
Gentek (our main line) and ProVia Endure
Vinyl
Gentek Signature Elite, our main line, and ProVia Endure are both vinyl windows. Each comes with a lifetime glass breakage warranty from its maker, which we pass on to you.
-
Andersen 100 Series
Fibrex composite
A blend of wood fiber and thermoplastic polymer that Andersen says is twice as strong as vinyl, with a finish that never needs painting.
-
By order
Another brand in mind?
Whatever window you order, we install it. Ask about another brand and we will explain how it compares before you choose.

Signs of failing windows
Signs a window is done
- Fog or moisture trapped between the panes
- A draft you can feel next to a closed window
- A sash that sticks, will not stay up, or will not lock
- A soft, rotted, or warped frame
- A room near the windows that never feels comfortable
Window glass options
The glass does most of the work
A window is mostly glass, so the glass package decides how much heat gets through. Here are the main Gentek Signature Elite options, with Gentek's own numbers.
- U-factor
- How easily heat passes through the whole window. Lower keeps winter heat inside.
- SHGC
- How much of the sun's heat comes through. Lower keeps summer heat outside.
BarrierXP
A Low-E coating that reflects heat, argon gas between the panes and a warm-edge spacer.
U-factor 0.29
SHGC 0.28
BarrierXPsc
Like BarrierXP, with a Low-E coating made to block more of the sun's heat.
U-factor 0.29
SHGC 0.21
Triple-pane
Three panes, two Low-E coatings, two spaces of argon and a stainless steel warm-edge spacer.

Insert or full-frame
Insert or full-frame: how to choose
Beyond the style, every replacement window goes in one of two ways. Here is the difference in plain words, so you can weigh it before we come over.
Keeps the old frame
Insert replacement
The old sashes come out and the new window fits inside the existing frame, so your trim and siding stay put. Andersen calls it the least disruptive option, and it only works when the frame is in good condition.
Replaces the frame
Full-frame replacement
The old window and its frame come out, and a new window with its own frame goes into the opening. It is the choice for a frame that is rotted, warped, out of square, or leaking air or water.
QuestionInsert replacementFull-frame replacement
What comes out The old sashes The whole window and frame
Frame it needs Sound, square, no leaks Fine for rotted, warped, or leaking frames
Trim and siding Stay as they are Not peeled back (flangeless)
Daylight A little less glass More glass than an insert
Cost Lower Higher
Insert and full-frame replacement at a glance (based on Andersen)
What about new-construction windows? A window with a nailing fin that sits under the siding, so using one as a replacement means peeling back siding or building a buck inside the opening. It is made for new walls and big remodels.

Questions before you replace
What people ask before they choose
How much do replacement windows cost?
The price of replacement windows mostly comes down to four things: how many windows you replace, their size and style, the window line (Gentek, ProVia or Andersen), and whether each one goes in as an insert or a full-frame replacement. We give you a price after we walk your home and look at every window together, and we point you to the option your house needs, not the most expensive one.
Should I get insert or full-frame replacement windows?
Insert replacement windows work when the existing frame is in good shape: the old sashes come out, the new window fits inside the old frame, and your trim and siding stay put. Full-frame replacement is the better choice when a frame is rotted, warped, out of square, or leaking air or water. Andersen notes that full-frame windows cost more than inserts. We look at each frame with you first.
Which is better: Gentek, ProVia or Andersen windows?
Gentek, ProVia and Andersen windows suit different priorities, so we show you all three. Gentek Signature Elite, our main line, carries Gentek's lifetime limited glass breakage warranty. ProVia Endure is also vinyl, and its warranty covers a home accident insurance does not pay for, or one under your deductible. Andersen's 100 Series is Fibrex, a wood-fiber composite Andersen says is twice as strong as vinyl.
What do the U-factor and SHGC numbers mean?
U-factor and SHGC are the two energy numbers on a window's NFRC label. U-factor measures how fast heat passes through the window, and the lower it is, the better the window insulates. SHGC measures how much of the sun's heat comes through the glass, and the lower it is, the less solar heat gets in. ENERGY STAR sets its limits for each climate zone on these numbers.
Who installs T Town's replacement windows?
T Town's replacement windows are installed by T Town's own crew, not subcontractors, trained by owners Andrey and Vadim Napelenok. Most jobs are done start to finish by one crew, and the brothers supervise and help with materials. Both brothers have completed Level 2 of Renewal by Andersen's Certified Master Installer program and are certified renovators under the EPA's lead-safe (RRP) rule.
What warranty comes with replacement windows from T Town?
Replacement windows from T Town come with two warranties: our 1-year workmanship warranty on the installation, and the manufacturer's warranty on the window itself, which we pass on to you. Gentek windows, for example, carry Gentek's lifetime limited glass breakage warranty, and ProVia's Endure warranty covers accidental glass breakage at home that insurance does not pay for. We walk you through what each one covers before you choose, and our warranty guide compares them side by side.

T Town Windows & Doors reviews
What our customers say
- ★★★★★ Replacement windows
We had an outstanding experience with Andrey, Vadim, and the entire installation team. They were professional, highly skilled, and took obvious pride in their work from start to finish. The crew arrived on time, worked efficiently, paid close attention to detail, and treated our home with care. The quality of the installation exceeded our expectations, and they made sure everything was cleaned up before they left. It’s refreshing to work with craftsmen who are knowledgeable, courteous, and committed to doing the job right. I would highly recommend Andrey, Vadim, and their team to anyone looking for top-quality window installation.
Keith N.Google review · Renewal by Andersen job - ★★★★★
Vadim & Andrey were terrific! Professional and thoughtful, took time before they got started to answer our questions and again at the end to make sure we were happy and knew how to work and care for our awesome new windows. They took the time to hear my concern about how two different windows may be ‘set back’ differently compared to the brick facade, talked to me about how they would adjust for it and executed perfectly. They do great work, things look very well finished and these guys caulk lines are second to NONE!! Thanks guys, will be recommending we get you for phase 2!
Mike B.Google review · Renewal by Andersen job - ★★★★★
We got our windows installed today by renewal by Anderson‘s. Our installers were.Vadim and Andrey. They were kind, informative of what they were doing and very professional. They cleaned up everything. The windows are beautiful. We were so impressed. I wished I did this a long time ago. Thank you so much!
Shawn Y.Google review · Renewal by Andersen job - ★★★★★ Replacement windows
Installation day I did not know what to expect. Vadim's and Andre's crew showed up shortly after 8 am. The entire 5-man crew worked diligently through the heat and high winds. They were all polite and answered any questions I had. They covered my furniture and put down carpet to protect my belongings. I was amazed at the speed and efficiency of the crew; they worked as a team and installed all 19 windows in one day. The crew vacuumed the carpet and cleaned up their work area. My previous windows were so foggy I had forgotten what a beautiful view I have of my backyard. My windows no longer sing when the wind blows and they make it much quieter. Thank you for a job well-done.

Danton V.Google review · Renewal by Andersen job - ★★★★★
Wanted to say thank you to Vadim and Andrey and their team for the great work on my new windows and door. Was told it take all day and they were finished in about 5 hours. They went over instructions on how to open and close and take the screens out, cleaned up and took all the old windows and door. I’m very impressed with their work and the windows are amazing! Once again thank you guys for the hard work and timely service!
