What customers say

Reviews from homeowners we have worked for

  • ★★★★★ 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.

Sand Springs homes, three eras

Which Sand Springs house is closest to yours?

Sand Springs grew from a 1911 townsite to 19,873 people in 2020, and its owners tend to stay: about four in ten moved in before 2010, so a warranty that runs while you own the home has time to matter.

  • A white clapboard farmhouse with a trimmed front porch, two porch swings, double-hung windows and a carved wood front door between climbing vines

    Older home

    A farmhouse or cottage from the early decades

    About one Sand Springs home in four, 26.1 percent, was built in 1959 or earlier, and 624 of them before 1940. A house this old predates 1978, so a paid contractor disturbing its painted window frames falls under EPA's lead rule; Andrey and Vadim are EPA lead-safe certified renovators.

    • Built before 1978: EPA's lead rule applies
    • Arched and circle-top window shapes
    • Storm doors for the front step
    Storm doors
  • A one-story tan brick ranch home with a carport, wood shutters and a covered front porch behind a wide green lawn

    1960s to 1980s

    A brick ranch from the growth years

    Sand Springs went from 7,754 people in 1960 to 15,346 in 1990, and homes from those three decades make up 34.5 percent of the city's housing today, 2,861 in all. The 1970s alone added 1,236, and the ones built before 1978 fall under EPA's lead rule too.

    • Gentek coverage while you own and live there
    • Sliding or hinged doors for the back patio
    • 1-year workmanship warranty from us
    Patio doors
  • A new white two-story home with board-and-batten and shingle siding, black shutters and a two-car garage beside a fresh lawn

    Newer home

    A house from the 1990s on

    39.3 percent of Sand Springs homes were built in 1990 or later, and the 2000s were the busiest decade, with 1,295. If you bought one from its first owner, ask whether the window warranty was transferred: Gentek's can pass to a new owner once, within 30 years, with the new owner paying a prorated share from year 11.

Sand Springs, then and now

Charles Page's town, and the storms it has seen

What the Oklahoma Historical Society, the Census and NOAA's storm records say about Sand Springs, and which part of a new window each warranty covers when the weather turns.

Who covers which part of a Gentek vinyl window
1 2 3 4 5 6

Gentek covers

  1. Vinyl frame and sashes

    Gentek's lifetime limited warranty covers them for as long as the original owner owns and lives in the home. Factory exterior colors are covered for 10 years.

  2. The glass seal

    A failed seal on the sealed glass unit, the kind that lets fog in between the panes, falls under the same lifetime limited warranty.

  3. Lock and moving parts

    The moving parts are covered too, and Gentek pays the labor for the first year after the window is installed.

  4. The screen

    The screen is part of the same warranty, under the same original-owner terms.

We cover

  1. The installation

    Our 1-year workmanship warranty covers how the window was put in. Gentek's warranty leaves out installation and caulking.

Not covered

  1. Glass broken by hail

    Gentek's separate glass breakage warranty sends a new sealed glass unit when glass breaks or cracks, but it excludes acts of God such as hail, floods and fire. The homeowner pays shipping and handling, and installation is not included.

Gentek's terms as written in its Lifetime Limited Warranty for windows and patio doors (effective June 1, 2019) and its Lifetime Limited Glass Breakage Warranty (effective February 1, 2021), single-family homes only. Not to scale. Sources: Gentek, Lifetime Limited Warranty (2019) and Lifetime Limited Glass Breakage Warranty (2021); T Town Windows & Doors, 1-year workmanship warranty.

Window replacement contractors

Warranty answers to get in writing

A new window or door usually carries two warranties: the maker's on the product and the installer's on the work. Ask any Sand Springs contractor these, us included.

  • Which warranty covers the installation, and for how long?

    A window maker's warranty is about the product. Gentek's lifetime limited window warranty does not cover installation or caulking, so the work itself needs a warranty of its own.

    Our answer: Our workmanship warranty covers the installation for 1 year.

    Gentek, Lifetime Limited Warranty (2019)

  • Whose lifetime is the lifetime warranty?

    The FTC's guide to federal warranty law notes that "lifetime" can mean the life of the product, as long as the first buyer owns it, or the buyer's own life. Gentek's runs as long as the original owner owns and lives in the home.

    Our answer: Every manufacturer warranty is passed on to you and explained, Gentek's included.

    FTC, Businessperson's Guide to Federal Warranty Law; Gentek

  • What happens to the warranty if I sell the house?

    Gentek's window warranty can be transferred once, within 30 years, and the new owner pays a prorated share from year 11. Its glass breakage warranty cannot be transferred at all.

    Check first: Keep the warranty papers and the install date with your house records for the next owner.

    Gentek, Lifetime Limited Warranty and Glass Breakage Warranty

  • Does any of it cover hail?

    Gentek's glass breakage warranty excludes acts of God, hail among them, and NOAA's records show hail up to 3 inches across around Sand Springs in 2015. James Hardie's HZ10 siding warranty, by contrast, names hail among what it covers.

    Check first: Ask your homeowner's insurer how it handles hail damage to windows and siding.

    Gentek; James Hardie HZ10 warranty; NOAA Storm Events Database

  • Who pays the labor on a warranty claim?

    Gentek covers labor for the first year after installation. Under its glass breakage warranty the new glass unit is free, but the homeowner pays shipping and handling and the installation is not covered.

    Check first: Ask what it costs to have a warranty part put in after the first year.

    Gentek warranties

  • Can I read the warranties before I sign?

    The FTC's guide says a seller who sells warranted products in your home must offer you copies of the written warranties before the sale is completed.

    Check first: Ask for the maker's warranty and the installer's warranty with the quote, and read what each one leaves out.

    FTC, Pre-Sale Availability Rule (16 C.F.R. Part 702)

Entry door installation

The doors that face the Sand Springs weather

Whose warranty stands behind each kind of door, and what the City asks before a bigger door job.

  • Dark stained double entry doors with divided glass panels on a covered porch with gray siding, white columns and two wicker chairs

    Entry doors

    An entry door's warranty comes from its maker, so the brand on the quote sets the terms. Widening the opening is a bigger job than a swap, and the City of Sand Springs says a building permit is needed before alterations or remodeling begin.

    Entry doors
  • A white hinged glass patio door with a transom above it, open from a dining room with wood floors onto a deck

    Patio and sliding doors

    Gentek's lifetime limited warranty covers its sliding patio doors: the frame and panels, the rollers and lock, seal failure and the screen, with labor for the first year. Its glass breakage warranty leaves patio doors out.

    Patio and sliding doors
  • A full-view glass storm door at the top of dark front steps on a cream lap-siding cottage, between a cedar porch post and wood shutters

    Storm doors

    A storm door takes the rain, wind and debris before the entry door does, Pella says, which helps that door's finish last. Pella also warns that its glass traps heat, and suggests skipping one if the porch gets more than a few hours of direct sun a day.

Sand Springs window questions

Warranties, permits and storms

Do you replace windows in Sand Springs?

T Town Windows & Doors replaces windows in Sand Springs, about 8 miles west of downtown Tulsa in a straight line. Brothers Andrey and Vadim Napelenok run the company from Tulsa, and their own crew installs Gentek Signature Elite vinyl windows, the Andersen 100 Series and other brands by order, along with entry, patio and storm doors and vinyl or James Hardie siding.

Is the estimate free in Sand Springs?

Estimates in Sand Springs are free. There is no showroom, so we come to the house with samples and brochures, look at each window and door with you, and explain what each opening needs. The visit covers everything we install: windows, entry, patio and storm doors, and siding.

What warranty comes with new windows in Sand Springs?

New windows from T Town Windows & Doors come with two warranties. Our own 1-year workmanship warranty covers the installation, and the manufacturer's warranty is passed on to you and explained. On Gentek windows that is a lifetime limited warranty on the frames, sashes, moving parts, screens and glass seal for as long as the original owner owns and lives in the home.

Does a window warranty cover hail damage?

Hail damage to window glass is not covered by Gentek's glass breakage warranty, which excludes acts of God such as hail, floods and fire. That warranty covers glass that breaks or cracks for other reasons, with a new sealed unit sent at no charge, though the homeowner pays shipping and handling and the installation. For hail, ask your homeowner's insurer how it handles windows.

Can the Gentek window warranty be transferred to a buyer?

Gentek's lifetime limited window warranty can be transferred to a new owner once, within 30 years, and after the transfer the new owner pays a prorated share from year 11. Gentek's glass breakage warranty is different: it cannot be transferred and lasts only while the original buyer owns and lives in the home.

Do I need a permit to replace windows in Sand Springs?

A Sand Springs building permit is required before alterations or remodeling begin, the City's permit guideline says, while cosmetic work and routine repair and maintenance can go ahead without one. The guideline does not name window replacement either way, so call Neighborhood Services at (918) 246-2572 about your job, especially if an opening gets bigger.

How often does hail hit Sand Springs?

Hail an inch or larger was reported around Sand Springs eight times from 2015 through 2024, on four separate days, according to NOAA's Storm Events Database. The largest, 3 inches across, fell on March 25, 2015, the day an EF2 tornado tracked from Keystone Lake to the south side of town.

Do you install James Hardie siding in Sand Springs?

James Hardie fiber cement is one of the two sidings T Town Windows & Doors installs in Sand Springs, along with vinyl. Oklahoma is in Hardie's HZ10 zone, and its HZ10 siding carries a 30-year non-prorated warranty that names hail among what it covers, while tornadoes, floods and severe weather are listed as acts of God it excludes.
