Window installer reviews
What customers say about the crew
- ★★★★★ 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.

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!

Shawn Y.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!
Landy P.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.

Tulsa houses by era
Which Tulsa house is yours?
Tulsa's houses changed as the city grew south, and the rules and questions that come with new windows change with them.
-
Older midtown home
A home from Tulsa's oil-boom years
In the 74104 and 74120 ZIP areas, about half the homes were built in 1939 or earlier. If yours is in one of Tulsa's eight historic preservation districts, exterior changes need a Historic Preservation Permit first, and a replacement window must match the original's sash design, size, muntin pattern and glass area.
- Check your address on the City's historic districts map
- Double-pane glass is allowed in the districts
- Brady Heights and Elmwood also require the original material
-
Postwar ranch
A ranch or cottage from the postwar years
Heading south from midtown, the median home in the 74114 ZIP area was built in 1954 and in 74105 in 1964. A house from before 1978 can have lead paint on its window frames and trim, and the EPA requires anyone paid to disturb it to be certified: Andrey and Vadim are EPA lead-safe certified renovators.
- Same-size windows need no City of Tulsa building permit
- Ask how lead-safe work is set up before the job
- A new entry or storm door fits these porches too
-
South Tulsa home
A South Tulsa house from the 1980s or 1990s
In the 74133 and 74137 ZIP areas, three in four homes were built in 1980 or later, and the median homes date from 1989 and 1990. Away from the historic districts, the questions are about performance: the U-factor and solar heat gain printed on each window's label.
- ENERGY STAR asks windows here for U-0.28 or lower
- Oklahoma's code maximum is U-0.35
- Patio doors and storm doors for the back and front

- 74114 1954 87.2% built 1979 or earlier
- 74105 1964 79.1% built 1979 or earlier
- 74136 1980 49.5% built 1980 or later
- 74133 1989 75.1% built 1980 or later
- 74137 1990 75.6% built 1980 or later

Oil filled the oldest neighborhoods
Oil at Red Fork in 1901 and Glenpool in 1905 turned Tulsa into a boomtown of 18,182 people in 1910 and 141,258 by 1930, the Oklahoma Historical Society records. That growth still shows in the houses: about half the homes in the 74104 and 74120 ZIP areas were built in 1939 or earlier.

Eight districts need approval first
Brady Heights, Gillette, North Maple Ridge, Swan Lake, Yorktown, Tracy Park, Elmwood and the Council Oak Tree Site have historic preservation zoning. There the Tulsa Preservation Commission approves exterior work before it starts, each window replacement needs a window survey, and an application usually goes to two meetings.

-
Same-size windows skip the city permit
Outside those districts, the City of Tulsa lists replacing existing windows of the same size and location among the jobs that need no building permit. Doors are not on that list, and a larger or brand new opening is a different job, so ask the city before work starts.
-
The numbers on a window label
Tulsa County is in climate zone 3A. Oklahoma's 2024 residential code, in force since September 14, 2026, sets a maximum window U-factor of 0.35 in that zone, while ENERGY STAR asks windows for Tulsa's region for 0.28 or lower and a solar heat gain coefficient of 0.23 or lower.
Window replacement contractor
Six questions to ask before you sign
Ask any Tulsa contractor these, us included. Each one comes from a city, state or federal rule, or from what a homeowner needs to know.
-
Who installs the windows: your crew or a subcontractor?
The company that sells a job is not always the one that installs it, so ask by name who will be working in your house.
Our answer: Our own crew, with no subcontractors. Andrey and Vadim supervise and work on site.
-
Is my house in a historic preservation district?
In Tulsa's eight HP districts the Preservation Commission approves exterior work before it starts, and each window replacement needs a window survey with the application.
Check first: Look up your address on the City of Tulsa's historic districts map.
Tulsa Preservation Commission
-
Was the house built before 1978?
The EPA's lead rule covers anyone paid to disturb painted surfaces in a home built before 1978, such as old window frames and trim, and requires them to be certified.
Our answer: Andrey and Vadim are EPA lead-safe certified renovators, through July 2030.
U.S. EPA, Renovation, Repair and Painting Program
-
What are the U-factor and SHGC of this exact window?
Oklahoma's code allows up to U-0.35 in Tulsa's climate zone, while ENERGY STAR's limits for the region are U-0.28 and an SHGC of 0.23, so the label shows which one you are buying.
Check first: Ask for the rated numbers of the window on your quote, not the brand's best line.
OUBCC IRC 2024 rule; ENERGY STAR Version 7.0
-
Same size, or a new opening?
The City of Tulsa needs no building permit to replace windows of the same size and location. A larger window or a new door opening is not covered by that.
Check first: Ask who applies for the permit if your job needs one.

-
What does the warranty cover, and who honors it?
There are usually two: the installer's workmanship warranty and the maker's product warranty, each with its own terms.
Our answer: A 1-year workmanship warranty from us, and every manufacturer warranty passed on to you and explained.
Door installers
Entry, patio and storm doors for Tulsa homes
What to know about each door in Tulsa, from the historic district rules to the ENERGY STAR numbers.
-
Entry doors
ENERGY STAR sets limits by how much glass a door has: a U-factor of 0.17 or lower for a solid door, and 0.23 or lower with a solar heat gain coefficient of 0.23 for a door that is up to half glass.
In a historic district: a replacement door should suit the home's architectural style, and new door and sidelight glass must be clear.
Entry doors -
Patio and sliding doors
A door that is more than half glass is held to the same limits as a window in Tulsa's region: a U-factor of 0.28 or lower and a solar heat gain coefficient of 0.23 or lower. Turning a window into a door is a new opening, so check the city's permit rules first.
Patio and sliding doors -
Storm doors
A storm door adds a glass or screen panel in front of the entry door you already have, so the door itself stays where it is.
In a historic district: a storm door must keep the original door in view and cannot be unfinished or clear-finished metal, and commission staff can approve it.

Tulsa window and door questions
Asked about Tulsa houses
Which Tulsa neighborhoods have historic preservation zoning?
Eight Tulsa areas have historic preservation zoning: Brady Heights, the Council Oak Tree Site, Gillette, North Maple Ridge, Swan Lake, Yorktown, Elmwood (the Patrick J. Hurley Mansion) and Tracy Park, zoned in 2022. Being listed on the National Register of Historic Places is separate from HP zoning, so check the City's map for your own address.
Can I put vinyl windows in a Tulsa historic district?
Tulsa's historic district guidelines for windows do not name vinyl. They say a replacement for a deteriorated historic window must match the original in sash design, size, shape, muntin pattern, location, glazing area and tint, and double-pane glass may be used. Brady Heights and Elmwood also require the original material, and the Tulsa Preservation Commission decides each application.
How long does a Historic Preservation Permit take in Tulsa?
A Historic Preservation Permit application in Tulsa typically goes to two meetings: first the HP Permit Subcommittee, then the full Tulsa Preservation Commission, which approves or denies it. If it is approved, the permit is usually issued within a few business days. Storm windows and storm doors can be approved by commission staff instead.
Do I need a permit to replace a front door in Tulsa?
A front door replacement in Tulsa is not on the City's list of jobs that need no permit, which names same-size windows but not doors. The City's general rule says a building permit is typically needed to build, remodel, move or repair windows or doors, so call the City's Building Permit Center about your door before work starts.
What U-factor should new windows have in Tulsa?
Oklahoma's 2024 residential code sets a maximum window U-factor of 0.35 in climate zone 3, which includes Tulsa County. ENERGY STAR's Version 7.0 limits for the South-Central region, which also covers Tulsa County, are tighter: a U-factor of 0.28 or lower and a solar heat gain coefficient of 0.23 or lower.
Who installs the windows when you hire T Town Windows & Doors?
T Town Windows & Doors' own crew installs every window and door, with no subcontractors. The company is run by brothers Andrey and Vadim Napelenok, who have installed windows, doors and siding around Tulsa for 17+ years and supervise and help on site. Both hold Renewal by Andersen Certified Master Installer certificates, Level 2.
Do you bring samples to my house in Tulsa?
Yes, T Town Windows & Doors brings samples and brochures to your Tulsa home, because there is no showroom to visit. We look at each window and door with you, explain the options in plain words, and estimates around Tulsa are free.
What warranty comes with a T Town Windows & Doors install?
Every T Town Windows & Doors install comes with a 1-year workmanship warranty, and the manufacturer's warranty is passed on to you and explained. For Gentek windows that includes a lifetime limited warranty for the original owner, and its glass breakage coverage excludes acts of God such as hail.
