Locally Owned Window Company in Tulsa, OK
Two brothers who treat every house like a $1 million house
T Town Windows & Doors is brothers Andrey and Vadim Napelenok and the crew they trained. We have spent 17+ years installing windows, doors and siding in Tulsa.
Founded by two brothers
From installing for others to doing it right ourselves
Andrey and Vadim came to the US from Ukraine 27 years ago and have worked in construction most of their lives. Windows and doors are the part they enjoy most.
For years the brothers installed windows, doors and siding for other Tulsa companies, and went through multiple training certifications along the way. Again and again they saw cheap windows and poor workmanship sold to good people.
So they started T Town Windows & Doors together, to give Tulsa homeowners better options, better quality and better service. They walk every home with the homeowner, explain the approach, and treat every house like a million-dollar house, because it is someone's sanctuary.
- Both Renewal by Andersen Certified Master Installers, Level 2
- Both EPA RRP Certified Renovators (lead-safe), through July 2030

T Town Windows & Doors customer reviews
In our customers' words
- ★★★★★ 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.
