A front door you are proud to open
We look at your door and its frame with you, explain fiberglass, steel and wood in plain words, and our own crew installs the door you choose.
The front door is the first thing a guest sees and the one you lock every night. When it lets in drafts, sticks, or will not latch without a shove, you feel it every day.
We look at the door, the frame and the threshold with you first. Sometimes the trouble is weatherstripping or a loose hinge; when it is time for a new door, we explain fiberglass, steel and wood side by side so you do not pay for more than your house needs.
An entry door can stand alone or come with glass sidelights beside it and a transom above. Then there is what the door is made of. Here is each one.
Seen from outside, each door in its trim with its glass, the way it would look on your house.
One door in its frame. The common size is 36 by 80 inches.
A tall, narrow glass panel beside the door for light in the entry.
Glass on both sides, which makes the whole entry wider and brighter.
A glass panel above the door, for light without glass beside it.
Two doors that open from the middle, for a wide, grand entry.
Glass on both sides and above: the most light an entry can have.
Three materials, each with its own strengths. Fiberglass and steel are compared side by side further down.
Fiberglass
Resists dents and can look like painted or stained wood. A windowless fiberglass door insulates to about R-5 to R-6. It can crack under an extreme impact.
Steel
Usually the lowest-cost door, with the same R-5 to R-6 insulation. It dents, and a scratch rusts unless it is repainted.
Wood
The classic look, and the highest upkeep. A windowless wood door insulates to about R-2 to R-3, and moisture is its enemy.
Sizes: Therma-Tru's dimensional data. Insulation and upkeep: Bob Vila (2025) and HomeGuide. The brand for your door is chosen with you at the estimate.
Short answer: Replacing a single front door costs $500 to $2,500 or more installed, by HomeGuide's national figures. The door alone runs about $200 to $1,000 for a basic steel door, $700 to $3,000 for steel with decorative glass and sidelights, $300 to $2,000 for fiberglass and $500 to $2,500 for solid wood.
What a single front door costs installed, then the door alone by material and the labor on top. These are national figures, not our prices: the cheapest steel door is not what most homeowners end up paying.

Each sidelight adds $500 to $1,500 or more installed, and a transom window $200 to $1,000 or more for the part alone, by HomeGuide.
A sound frame can stay if the new door is exactly the same size. Otherwise a prehung unit replaces both.
We start by looking at your door with you, and explain what fits.
Replace the front door
Most front doors are replaced as a prehung unit: the door already hung in its own frame, with the sill, threshold and hinges installed, so the old door and frame come out together and nothing is pieced.
Back and side doors
Back and side doors get the same choices as the front: fiberglass, steel or wood, with glass or without, single or double.

Most front door trouble starts in one of six places. Here is what you notice, and whether it usually means a repair or a new door.
You notice: soft wood or rot at the bottom of the frame.
A sound frame can stay if the new door is exactly the same size. A rotting one goes, and a prehung door brings a new frame with it.
You notice: the door sags and rubs at the top on the latch side.
Loose hinge screws let a door drop. Police guidance is at least one 3- to 4-inch screw in each hinge, reaching the wall stud.
You notice: dents, cracks, warping or a finish that keeps peeling.
Steel dents and rusts once scratched; fiberglass can crack under an extreme impact. A warped slab will not seal again, and that is a new door.
You notice: drafts, or daylight around the edges and under the door.
The seals wear out long before the door: InterNACHI says exterior door weatherstripping may need replacing every five to eight years.
You notice: you have to lift or push the door to lock it.
Usually a sagging door or a strike out of line. The deadbolt should throw at least 1 inch into a strike held with long screws.
You notice: water under the door, or a soft sill below it.
A worn sweep is a small fix. A rotted sill means the frame is going, and a prehung door replaces the sill and threshold together.
Not sure which it is? On your free estimate we look at the door with you and tell you straight whether a part would fix it or it needs a new door.
Windowless fiberglass and steel doors insulate about the same. They differ in price, dents and upkeep.

Police crime-prevention guidance starts with the frame, not the lock. Seen from above, here is where a deadbolt holds, and why the screws behind the strike plate matter.
The bolt should reach at least 1 inch into the frame. Lock grades run from ANSI/BHMA Grade 1, the highest and mostly commercial, to Grade 3.
The metal plate the bolt slides into. A heavy-duty, four-screw strike plate spreads a kick across more of the frame.
Strike plates and hinges are often held by short screws that stop in the thin wood jamb. Seattle Police guidance says to take them out and replace them.
Screws of 3 to 4 inches reach through the jamb and shims into the wall stud. Police guidance says a heavy-duty strike plate held this way will deter or prevent most through-the-door forced entries.
Ask about your door's lock and frame on your free estimate. We look at the deadbolt, the strike and the frame with you and explain what would make them stronger.

Two real front doors we replaced. Pick one and drag the handle across the photo.
The owners traded a pair of iron double doors for one door with a sidelight on each side. It went into the same stone opening, with new cedar trim around it.
A full-glass door came out and an arched entry door with iron scrollwork went in. The after photo is from install day, before the trim above it was finished.

Entry door replacement costs $500 to $2,500 or more for a basic single door the same size as the old one, and $1,500 to $6,500 or more for double doors, by HomeGuide's national figures. Sidelights add $500 to $1,500 or more per side. Angi's Tulsa data for door installation of all kinds, interior doors included, shows a $1,078 average, with most jobs between $405 and $1,865. These are published figures, not our prices; your estimate is free.
Neither entry door is better for every house. Windowless fiberglass and steel doors both insulate to about R-5 to R-6, against R-2 to R-3 for wood, by Bob Vila's comparison. Steel usually costs less but dents, and a scratch rusts unless it is repainted. Fiberglass resists dents and can take a wood-grain finish, but costs more and can crack under an extreme impact.
You can replace a front door without the frame if the frame is in good condition and the new door is exactly the same size as the old one, in height, width and thickness, HomeGuide says. A soft or rotting frame, or a different size, calls for a prehung door: a new door already hung in its own frame, with the sill, threshold and hinges installed, as ProVia describes its prehung units.
Yes, T Town can add sidelights beside an entry door or widen the opening to fit a wider door. Both change the wall around the door, not only the door itself, so we look at the opening, the framing and the trim with you first and price the job after that visit.
Replacing a basic single front door with one of the same size typically takes 3 to 8 hours, by HomeGuide. Double doors, a full frame replacement, frame repairs or sidelights take longer, and painting a new door adds about an hour per side, with a day of drying between sides.
An entry door can last as long as the house: InterNACHI's life expectancy chart lists fiberglass, fire-rated steel and wood exterior doors at 100 years or more, and says exterior fiberglass, steel and wood doors will last as long as the house. The parts wear out first: InterNACHI says the gaskets and weatherstripping on exterior doors may have to be replaced every five to eight years.
Front doors commonly come 36 by 80 inches. Therma-Tru's 36 by 80 fiberglass prehung unit measures 37-5/8 by 82 inches and needs a rough opening of 38-1/2 by 82-1/2 inches, or 38-1/2 by 96 with a transom. Oklahoma's residential code (2024 IRC R318.2) requires every home to have at least one side-hinged egress door with a 32-inch clear width and a 78-inch clear height.
To make a front door more secure, anchor it to the wall framing. Seattle Police crime-prevention guidance says a four-screw, heavy-duty strike plate installed with 3- to 4-inch wood screws into the stud will deter or prevent most through-the-door forced entries, and that long screws in the existing strike plates alone will vastly improve security. A deadbolt should throw at least 1 inch. Lock grades run from ANSI/BHMA Grade 1, the highest, to Grade 3.
Yes, glass in a front door has to be safety glass. The 2024 International Residential Code, which Oklahoma adopted on September 14, 2026 (the City of Tulsa lists its own update as pending for January 1, 2027), treats glass in swinging doors as a hazardous location (R324.4.1; R308.4.1 in the 2018 edition the City of Tulsa still lists), except openings a 3-inch sphere cannot pass through and decorative glazing.
Yes, entry doors can be ENERGY STAR certified, with the limits set by how much glass they have. Under Version 7.0, a door with no glass needs a U-factor of 0.17 or lower; a door with up to half glass needs a U-factor and solar heat gain of 0.23 or lower; a door with more than half glass needs 0.28 or lower and 0.23 or lower in the South-Central and Southern climate zones. Lower U-factor means less heat escapes.
Usually yes: the City of Tulsa says a building permit is typically required to build, remodel, move or repair walls, floors, ceilings, windows or doors, and its list of work that needs no permit names same-size windows but not doors. Tulsa Development Services (918-596-9456) can confirm for your house.
T Town's own crew installs every entry door, with no subcontractors. It is a trained, long-time crew. The brothers who own the company, Andrey and Vadim, supervise the work and help with materials, and bring in extra hands they have worked with before on big jobs.
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!
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!
We got our windows installed today by renewal by Anderson‘s. Our installers were.Vadim and Andrey. They were kind, informative of what they were doing and very professional. They cleaned up everything. The windows are beautiful. We were so impressed. I wished I did this a long time ago. Thank you so much!
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.
Vadim and his team did a fabulous job. They exceeded my expectations. Windows are beautiful, functional and have transformed the look of my home.
These window installers surpass professionalism. They were prompt curtious and friendly professional. Above all they worked quietly and very efficient. Vadim and Tim were two very unique individuals. I will recommend their service to everyone. Thank you gentlemen my house is already much cooler
