Window installer reviews

Reviews of Andrey and Vadim's work

  • ★★★★★ 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!

  • ★★★★★ 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.

Three kinds of Owasso house

Find your Owasso house

Owasso's homes went up in three rough waves, and the window and siding questions are different for each one.

  • A long one-story ranch with painted siding, dark shutters and a covered front porch with two front doors, its windows lit at dusk

    Older Owasso home

    A ranch from Owasso's first suburban years

    About 2,600 Owasso homes were built before 1980, most of them in the 1960s and 1970s, when the town grew from 2,032 people to 6,487. Lead paint is the question on any house built before 1978: the EPA's rule covers paid work that disturbs old painted window frames and trim, and both brothers hold EPA lead-safe renovator certificates.

    • Built before 1978? Ask about lead-safe work
    • Ask what is under the old siding before it comes off
    • A storm door for the front porch
    Replacement windows
  • A two-story home with blue-gray lap siding, navy shutters, a small columned front porch and a two-car garage

    1990s house

    A 1990s house on the Tulsa County side

    The 1990s added 2,846 homes to Owasso, and the median home in the Tulsa County part of the city was built in 1999. A house that age may still have the windows and the siding it was built with, so if both are on your list, ask for one plan that covers the windows, the flashing around them and the siding together.

    • Windows and siding on one plan
    • Ask how the wrap and flashing are handled
    • Vinyl or James Hardie, side by side
    Siding
  • A two-story home with a stone front gable, shake and board-and-batten siding, black shutters and a covered front porch

    2000s or newer

    A newer house on the Rogers County side

    On the Rogers County side of Owasso, the median home was built in 2008. On a house this young you may be replacing only a few windows or adding a patio door while the siding stays, so ask how the new window's flashing and trim will meet the siding that is already there.

    • Check the window maker's warranty first
    • A new patio door for the deck
    • Ask how the siding meets the new trim
    Patio doors

Owasso homes and how they grew

A Tulsa bedroom town that built fast after 1990

Census and state history figures for Owasso, the City's own rules, and what goes around a window when the siding comes off.

Around one window with the siding off: what goes on, in order

From outside

Sheathing House wrap 123456

Cut through the top

Outside Inside Siding Trim Drip cap Wrap flap Top flashing Flange Window Water runs off 775653

  1. House wrap first

    The weather barrier goes on the wall before the window. Andersen's guide folds its sides into the opening and cuts a flap above the top, taped up out of the way for now.

  2. Flashing at the bottom

    A strip of flashing tape goes across the bottom of the opening and up its corners, so the sill is sealed before the window sits on it.

  3. The window, set in sealant

    A bead of sealant runs along the top and sides of the opening, the window goes in on shims, and it is fastened through its nailing flange.

  4. Side flashing

    Flashing goes over each side flange and laps over the bottom piece, never under it, so water running down stays on the outside.

  5. Drip cap, then top flashing

    A drip cap goes across the top in sealant, then flashing over its leg and over the side pieces. Andersen warns that side flashing must never reach above the top flashing.

  6. Wrap flap down

    The flap of house wrap cut above the window folds back down over the top flashing, and its cut edges are taped.

  7. Trim and siding last

    Then trim or J-channel, then siding. The VSI bends the top J-channel's tab down over the side pieces; James Hardie leaves a gap between plank and trim, then caulks it.

  • From Elm Creek to a Tulsa bedroom town

    The settlement began as Elm Creek in 1881 and took the name Owasso in 1900. It had 431 people in 1950. Then in 1952 its first new tract addition, Raywood, brought 68 homes, and the Oklahoma Historical Society says Owasso quickly became a bedroom community for a Tulsa that was growing north.

    Source: Oklahoma Historical Society, Encyclopedia of Oklahoma History and Culture, Owasso

  • Nearly half its homes date from 1990 to 2009

    Owasso went from 11,151 people in 1990 to 28,915 in 2010, and the houses kept pace: Census estimates count 2,846 homes from the 1990s and 4,836 from the 2000s, 7,682 of the city's 16,231. The median Owasso home was built in 2001.

  • The Rogers County side is the newest

    Most of Owasso is in Tulsa County, but the 2020 Census counted 4,138 residents and 1,598 homes in the city's Rogers County part. Homes there are the youngest in town: the median one was built in 2008, against 1999 in the Tulsa County part, and about 94 percent date from 2000 or later.

  • What the City's permit list names

    Owasso's Building Division asks for a residential building permit for any structural construction, alteration, remodel or reconstruction, and requires one for a re-roof. Window and siding replacement are not named, so ask the Building Division about your job first. Once an application is complete, residential review takes 7 to 10 business days.

    Source: City of Owasso, Building Permits and Inspections; Residential Building Permit form (updated February 2025)

  • Door-to-door sellers need a city license

    Owasso requires solicitors to buy a Solicitor's License, which includes a criminal background check for every salesperson, and to carry it along with ID. Residents inside the city limits can also join the City's No Knock List, which keeps solicitors other than non-profits from their door.

Siding contractor

Five questions for a windows-and-siding job

Replacing windows and siding at once, or one after the other? Put these to any contractor in Owasso, us included. Each comes from a maker's instructions, a warranty or a City of Owasso rule.

  • Do the windows go in before the siding?

    In Andersen's instructions for a flanged window, the house wrap and flashing go on around the window before anything covers the wall, and the Vinyl Siding Institute's manual prepares windows and doors before any siding goes up.

    Check first: Ask for the order of work on your house, wall by wall.

    Andersen; Vinyl Siding Institute

  • Is the house wrap being replaced or patched?

    James Hardie's instructions require a weather barrier, installed with flashing at openings and joints as local code requires, and Hardie's siding warranty does not cover water getting in or an install that skips its instructions.

    Check first: Ask what happens to the wrap when the old siding comes off.

    James Hardie, HZ10 instructions and limited warranty

  • How is a window that stays in place flashed?

    For a nail-fin window already in the wall with no flashing, the Vinyl Siding Institute calls for sill flashing at least 9 inches wide running 9 inches past each side, side flashing to about 8 1/2 inches above the top, and top flashing about 1 inch past the side pieces.

    Check first: Ask which windows keep their frames and how each one gets flashed.

    Vinyl Siding Institute

  • Who covers a leak around the window?

    Gentek's lifetime limited warranty does not cover installation or caulking, and Hardie's warranty leaves out water infiltration, so a leak at the joint comes back to whoever installed it.

    Our answer: Our 1-year workmanship warranty on the installation, and each maker's warranty passed on to you and explained.

    Gentek and James Hardie warranties

  • Can I see your city solicitor's license?

    Owasso requires anyone selling door to door to hold a city Solicitor's License, which comes with a criminal background check, and to carry it with ID.

    Check first: Ask to see it at the door, or call the City Clerk's office at 918-376-1502.

Patio door replacement

The three doors on an Owasso house

Every door sits in the same wall as the windows and the siding. What to know about each one when the outside of the house is being redone.

  • A stained wood front door with six glass panes at the top, open to a small foyer with a carpeted staircase

    Entry doors

    Where new vinyl siding meets a front door, the Vinyl Siding Institute's manual frames the opening with J-channel, the top piece's tab bent down over the side pieces so water is carried past the door instead of behind the siding.

    Entry doors
  • A white hinged glass door with a grid of panes opening onto a wood deck from a house with dark red lap siding

    Patio and sliding doors

    For flashing a door, the Vinyl Siding Institute points installers to the door maker's own instructions and ASTM E2112, the standard practice for exterior windows, doors and skylights. Gentek's patio door warranty covers the door, not its installation or caulking.

    Patio and sliding doors
  • A white storm door with a half-round window at the top, over the front door of a house with gray vertical siding

    Storm doors

    Pella measures for a new storm door between the edges of the trim or brickmould around the front door, at the top, middle and bottom, and takes the narrowest. If new trim is going on around the entry, the storm door is sized to that trim.

Owasso window and siding questions

Asked about Owasso houses

How far is Owasso from Tulsa?

Owasso is about 13 miles from downtown Tulsa in a straight line, and the Oklahoma Historical Society places it on U.S. Highway 169, six miles north of Tulsa's city limits. T Town Windows & Doors is based in Tulsa, its own crew does the work in Owasso, and estimates here are free.

Which county is Owasso, OK in?

Owasso is mostly in Tulsa County, with a newer part in Rogers County. The 2020 Census counted 34,102 residents in the Tulsa County part and 4,138 in the Rogers County part, where homes are younger: the median one was built in 2008, against 1999 on the Tulsa County side.

Should windows or siding be replaced first?

When both are being replaced, the installation guides put the windows in before the siding. Andersen's instructions flash a flanged window into the house wrap, and the Vinyl Siding Institute's manual prepares windows and doors before any siding goes up. The trim and siding then lap over the flashing, so water runs off instead of behind them.

What is window flashing?

Window flashing is the tape or metal around a window opening that sends water back outside. In Andersen's order it goes on from the bottom up: sill flashing first, side flashing lapped over it, then a drip cap and top flashing over the side pieces, with the house wrap folded down over the top.

Do I need a permit to replace windows or siding in Owasso?

The City of Owasso asks for a residential building permit for structural construction, alteration, remodel or reconstruction, and requires a permit for a re-roof, but its list does not name window or siding replacement. Call the Building Division at City Hall, 918-376-1540, about your job before work starts.

How do I stop door-to-door salespeople in Owasso?

Owasso residents inside the city limits can sign up for the City's No Knock List, which bars solicitors from their door, except non-profits such as schools, churches and youth groups. Every licensed solicitor receives a copy of the list and must carry a city Solicitor's License, which includes a criminal background check.

Does T Town Windows & Doors install siding in Owasso?

T Town Windows & Doors installs vinyl siding and James Hardie fiber cement siding in Owasso, along with replacement windows and entry, patio and storm doors, all with its own crew and no subcontractors. Brothers Andrey and Vadim Napelenok run the company, supervise each job and help on site.

What warranty comes with new windows and siding?

T Town Windows & Doors gives a 1-year workmanship warranty on its installation, and the makers add their own. Gentek's lifetime limited warranty covers its vinyl windows for the original owner, though not installation or caulking, and James Hardie's HZ10 siding warranty runs 30 years, not prorated. We pass each one on and explain it.
