What homeowners tell others about us
- ★★★★★ 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!

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.

Sapulpa homes, decade by decade
Find your Sapulpa house
Sapulpa's houses run from 1920s bungalows near downtown to ranches built after the war, and each era asks something different of a new window.
-
1920s bungalow
A bungalow from the brick and oil years
Around downtown about 1 in 3 homes date from 1939 or earlier. The Craftsman bungalow was the main style for modest homes from 1905 through the 1920s, with its windows set in groups. In the historic district, the City's guidelines ask for repair first and a replacement that matches the original in size and design.
- Historic district: a Certificate of Appropriateness first
- Keep each grouped opening its original size
- Gentek's Craftsman grid pattern
-
1940s cottage
A small cottage from the 1940s
Only about 3 percent of Sapulpa's homes, roughly 300, date from the 1940s. For postwar houses, the Oklahoma SHPO counts replacement windows that match the original size and configuration as a change that typically keeps a home's historic integrity, and altered window openings as one that takes it away.
- Divided panes: Colonial grids or Simulated Divided Lites
- Same opening size, same pane pattern
- A storm door for the front step
-
1950s ranch
A ranch from the postwar years
The 1950s and 1960s added 2,072 of Sapulpa's homes, about 1 in 5. The Oklahoma SHPO describes the ranch as low with wide eaves, its windows in metal or wood double-hung, casement, sliding and awning types, and a large picture window on the front as a common sight.
- A Gentek picture window for the front
- ENERGY STAR asks Sapulpa ZIPs for U-0.28 or lower
- Sliding or French doors to the back yard

Brick, glass and the railroad
The railroad reached Sapulpa in 1886, the Sapulpa Pressed Brick Company opened in 1898, and by the 1920s the town had four glass plants. Oil at Glenn Pool in 1905 nearly doubled the town, from 4,259 people in 1907 to 8,283 in 1910, and it reached 10,533 by 1930.

The oldest homes ring downtown
In Census tract 213, which takes in downtown and City Hall, about 1 in 3 homes were built in 1939 or earlier. Across the city the median home dates from 1977, and 55 percent of Sapulpa's 9,817 homes went up before 1980.

A National Register downtown
Downtown Sapulpa, on Historic Route 66, became a National Register historic district in 2002, and the City's historic zoning dates from a 1989 ordinance. Of the 208 buildings in today's downtown code area, 68 percent predate the Great Depression.
-
Historic houses have window rules
For a contributing house in the historic district, the City's guidelines say to repair windows rather than replace them. A replacement should match the original in size and design, wood is preferred, other materials must be paintable, and grids between the glass should not be used, though staff may approve easier-care materials.

Window installation for older homes
Six checks to keep your house's look
Before you order windows for a Sapulpa house built before about 1970, go through these with any installer, us included. Each one comes from the City, the state preservation office or the window maker.
-
Is the house in Sapulpa's historic district?
The Historic Preservation Commission's application says the listed work must be approved before it starts, and any change to approved work needs a new Certificate of Appropriateness.
Check first: Call the City at (918) 224-3040 with your address before anything is ordered.
City of Sapulpa, Certificate of Appropriateness application
-
What pattern do the windows have now: grouped, divided or picture?
A Craftsman bungalow's windows were set in groups, a Colonial Revival house usually had divided panes in one or both sashes, and a ranch often had a picture window on the front. That pattern is much of what gives each house its look.
Check first: Walk around the outside with your installer and note each opening's type and pane pattern before choosing.
Oklahoma City survey for the SHPO (2023); Oklahoma SHPO housing context (2014)
-
Will each new window fill the opening at its original size?
The Oklahoma SHPO counts replacement windows that match the original size and configuration among changes that typically keep a postwar home's integrity, and altered openings among those that do not. Sapulpa's district guidelines also ask for a match in size and design.
Check first: Ask whether any opening will be made smaller with filler, and by how much.
Oklahoma SHPO; City of Sapulpa
-
Which grid pattern, and where does it sit?
Gentek Signature Elite grids come in Colonial, Craftsman, Prairie, Diamond and Double Perimeter patterns sealed between the panes, or as Simulated Divided Lites with grids on both faces of the glass. Sapulpa's district guidelines say grids between the glass should not be used there.
Our answer: We bring samples and brochures to the house, so you can see the options next to your own windows.

-
New siding on an older house: what changes?
For National Register purposes, the Oklahoma SHPO lists modern siding such as vinyl among changes that take away a postwar home's integrity, and the City's district guidelines ask owners to keep the original cladding and match it in size, shape, finish and color if it must go.
Check first: If the district or a future listing matters to you, settle that before choosing vinyl or James Hardie siding.
Oklahoma SHPO; City of Sapulpa
-
Triple-pane glass, or Simulated Divided Lites?
Gentek's brochure says its Simulated Divided Lites, the grids fixed to both faces of the glass, are not available with triple-pane glass packages, so the look of true divided panes limits which glass can go with it.
Check first: Ask for the glass package and the grid type on every line of your quote.

Front door installation
Doors that suit the house's era
What to look for on each kind of door in Sapulpa, from ENERGY STAR's numbers to the City's historic district guidelines.
-
Entry doors
ENERGY STAR sorts swinging doors by how much glass they have. A door with up to 900 square inches of glass, such as one with a row of small panes across the top, needs a U-factor of 0.23 or lower and a solar heat gain coefficient of 0.23 or lower.
In Sapulpa's historic district: a replacement keeps the original opening and should be similar to the original door in style, glazing and pane layout.
Entry doors -
Patio and French doors
Sapulpa's ZIP codes 74066 and 74067 are in ENERGY STAR's South-Central zone, where a sliding glass door is held to the window limits: a U-factor of 0.28 or lower and an SHGC of 0.23 or lower. A hinged door that is more than half glass has the same two limits.
Patio and sliding doors -
Storm doors
A storm door goes in front of the entry door you keep, so an original bungalow or cottage door can stay where it is behind new glass or a screen.
In Sapulpa's historic district: original doors should be repaired rather than replaced, and original door openings should not be altered.

Sapulpa window and door questions
Asked about Sapulpa's older houses
Do I need a permit to replace windows in Sapulpa?
The City of Sapulpa says its Building Inspection Department issues building, sign and trade permits and that permits and inspections are required in most cases. Its page does not list window replacement as exempt, so call Building Inspection at (918) 248-5910 with your address and the job before work starts. In the historic district, the Historic Preservation Commission also approves the work first.
Which building code does Sapulpa use?
Sapulpa uses the 2024 International Residential Code as adopted by the State of Oklahoma, effective September 21, 2026, according to the City's adopted building code notice. The same notice adopts the 2024 International Existing Building Code, and the City's own changes are in Chapter 5 of the City Code.
Is my house in Sapulpa's historic district?
Sapulpa's historic zoning began with a 1989 ordinance centered on downtown, and the downtown was listed on the National Register as a historic district in 2002. The City's 2023 downtown code covers the area from the train tracks south to Thompson Avenue and west to mid-block between Poplar Avenue and Mounds Street. Ask the City about your address, because in the district the Historic Preservation Commission approves exterior work with a Certificate of Appropriateness before it starts.
Can I put vinyl windows in a Sapulpa historic house?
For a contributing house in Sapulpa's historic district, the City's design guidelines prefer wood replacement windows and say other materials must be paintable if approved, though staff may approve non-traditional materials with maintenance, durability or cost advantages. Grids between the glass should not be used. Those guidelines cover the historic district, not the rest of Sapulpa.
What windows did Sapulpa's older houses have?
Sapulpa's older houses had different windows in each era. Craftsman bungalows, the main style for modest homes from 1905 through the 1920s, have their windows set in groups; Colonial Revival houses usually have double-hung windows with divided panes in one or both sashes; and postwar ranches often have a large picture window on the front, with double-hung, casement, sliding or awning windows elsewhere. About 11.5 percent of Sapulpa's homes were built in 1939 or earlier.
Does vinyl siding change an older house's historic standing?
For National Register purposes, the Oklahoma SHPO lists installing modern siding such as vinyl among the changes that take away a postwar home's historic integrity. In Sapulpa's historic district, the City's guidelines ask owners to keep the original cladding and to match it in size, shape, finish and color if it has to be replaced. We install both vinyl and James Hardie siding, so ask about each at the estimate.
How far is Sapulpa from T Town Windows & Doors, and is the estimate free?
Sapulpa is about 13 miles from downtown Tulsa in a straight line, and the estimate at a Sapulpa address is free. We have no showroom; samples and brochures come with us to the house, and we go over each window and door with you there.
Who installs the windows on a Sapulpa job?
Every window and door on a Sapulpa job is put in by T Town Windows & Doors' own crew; no part goes to a subcontractor. Brothers Andrey and Vadim Napelenok run the company from Tulsa, have 17+ years in windows, doors and siding, and supervise each job and help on site. Both hold Renewal by Andersen Certified Master Installer certificates, Level 2, and every install carries our 1-year workmanship warranty.
