Commercial window replacement in Tulsa at a glance

Morgan Windows replaces windows in offices, churches, schools, retail centers and other commercial buildings across Tulsa and Northeastern Oklahoma. We bid each job opening by opening, install with our own crew, plan the work around the hours your building is open, and back every install with a 5-year workmanship warranty.

Pricing
Bid per project, line by line for each opening. Size, performance class, glass, access and work hours set the number. We send a written bid, not a phone guess.
Products
We are not tied to one manufacturer. We install the window your architect or spec calls for, or help you pick one when there is no spec.
Timeline
Custom windows usually arrive about 2 to 4 weeks after order. Your bid states the lead time for the exact product and how many openings we finish per day.
Warranty
Our 5-year workmanship warranty on the install, plus the manufacturer's warranty on the window, passed on to the owner.

By the numbers

Tulsa-area windows, doors and siding from a crew you can reach.

One local crew bids, schedules and installs every opening, and answers for it afterward.

Office, church and school window replacement

Every Kind of Building Has Its Own Rules

The windows may look alike from the parking lot. The schedule, the safety rules and the people inside do not.

Two-story office building with rows of windowsOffice window replacement

Offices and professional buildings

Medical, dental, legal and general office space. Work is usually phased suite by suite or after hours so phones stay answered and patients are not walking past an open wall. We match glass tint and frame color so new and old elevations look like one building.

Brick church with a white steepleChurch window replacement

Churches and fellowship halls

We schedule around services, weddings and funerals, and most church jobs are the clear windows in offices, classrooms, gyms and fellowship halls. Stained and leaded glass is art, and its repair belongs to a stained glass studio. If old storm glazing over it is fogged or yellowed, read the stained glass notes below before anyone replaces it.

Brick and glass school buildingSchool window replacement

Schools, preschools and daycare

Most school work is planned for summer and holiday breaks. In buildings built before 1978 where young children spend regular time, federal lead-safe rules apply to window replacement, and glass near doors and floors in halls and gyms often has to be safety glazing.

Small-town retail storefront with a flag out front at duskRetail

Retail and strip centers

Punched windows, transoms and the glass beside entrances in strip centers and stand-alone stores. We work with property managers on multi-tenant centers so each tenant gets notice and keeps a working entrance.

Metal shop building with a steel door and overhead door

Shops, warehouses and light industrial

Office fronts on metal buildings, clerestory windows and fixed glass in shop offices. Access by lift is common here, and it is priced into the bid.

Stained glass windows in a church

Stained glass and protective glazing

The National Park Service guidance on historic stained and leaded glass (Preservation Brief 33) is the best plain-language reference we know of. Its main points for a church board:

Protective glazing is a trade-off
An outer layer of glass or plastic can shield stained glass from wind, impact and UV light. It can also trap heat and condensation, add stress to the lead, and hide the window from the street.
It must breathe
The guidance says protective glazing should be ventilated, set in its own frame about 5/8 inch to 1 inch from the leaded glass so it can be removed for maintenance, and checked so condensation never collects on the window.
Glass or plastic
Plastic panels are light and strong but scratch, haze and yellow over time and move a lot with temperature. Glass costs more to install but does not bow, scratch or haze. Laminated glass adds impact resistance.

Start With the Situation That Sounds Like Your Building

Most commercial buildings stay open while we work. The written scope says which openings, in what order, on which days.

Open for business

The building stays open

We phase the work by floor, wing or elevation so only a few rooms are affected at a time. Each opening is closed and weather-tight before the crew leaves for the day.

  • Phasing plan in the bid
  • Work areas taped off and cleaned daily
  • Early, late or weekend days priced in when needed

What Building Owners Call Us About

Commercial bids are a large share of our work right now. The calls usually start with one of these problems, and the fix has to fit around people who still need to use the building.

Commercial window performance classes

R, LC, CW and AW: What the Class on the Label Means

Windows sold in North America are tested to one standard, AAMA/WDMA/CSA 101/I.S.2/A440, also called NAFS. It sorts windows into four performance classes. Each class has a minimum performance grade (PG), a number tied to the design pressure the window was tested to, in pounds per square foot. If your architect wrote a class and grade into the spec, that is what we bid.

NAFS window performance classes

Minimum performance grade

R Residential
Where it is typically used
One- and two-story residential buildings, townhouses and row houses with low wind loads
What changes as you move up
Smallest test size and lowest test pressures
LC Light Commercial
Where it is typically used
Low-rise and mid-rise buildings where larger windows and higher wind loads are expected
What changes as you move up
Larger test size, higher structural and water test pressures
CW Commercial Window
Where it is typically used
Low-rise and mid-rise buildings with larger windows, high wind loads and heavy use
What changes as you move up
Adds limits on how far the frame may deflect under load
AW Architectural Window
Where it is typically used
Mid-rise and high-rise buildings with high wind loads and frequent or extreme use
What changes as you move up
Deflection limits, a water test at 20% of design pressure instead of 15%, and testing at higher air pressure

The class is a starting gate, not a building-type rule. FGIA, the group that maintains the standard, says the class is chosen from the project's performance needs, not from what the building is used for, and a lower-class window can carry a higher grade. The performance label shows class, grade and tested size together, for example "LC-PG30". NAFS does not cover storefront, curtain wall or commercial entrance systems; those are specified and tested separately.

Commercial safety glazing requirements

Where Code Requires Safety Glass

Oklahoma's statewide building code is the International Building Code (IBC). The Oklahoma Uniform Building Code Commission adopted the 2024 edition, effective September 14, 2026. Section 2406 lists the "hazardous locations" where glass must be safety glazing that passes an impact test. The common ones on a window job:

Glass in doors

Glass in fixed and operable panels of swinging, sliding and bifold doors is a hazardous location (IBC 2406.4.1), with narrow exceptions such as openings too small for a 3-inch ball to pass through.

Glass next to doors

Glass within a 24-inch arc of either vertical edge of a closed door, where the bottom edge of the glass is less than 60 inches above the walking surface (IBC 2406.4.2). Sidelites and the windows beside an entrance usually land here.

Large, low windows

A single pane is a hazardous location when all four are true: it is over 9 square feet, its bottom edge is under 18 inches above the floor, its top edge is over 36 inches above the floor, and a walking surface is within 36 inches of the glass (IBC 2406.4.3).

Marked so an inspector can see it

Each pane of safety glazing in a hazardous location must carry a permanent mark (etched, fired or similar) naming who applied it and the safety glazing standard it meets (IBC 2406.3). We order glass with the mark where code requires it.

Energy code

Replacement windows also have to meet the energy code your local building official enforces. When there is an architect or a required U-factor and SHGC, we bid to those numbers. When there is not, we show you the label numbers for each option.

Your local building official has the final say on what applies to your building, and some cities amend the state code. These are the code sections we check on every commercial window bid.

Commercial window replacement cost

How a Commercial Bid Is Priced

We do not publish a commercial price range because no two buildings are alike. Every bid is built from the same line items, and you see each one.

Per opening

Each opening is priced by size, operation (fixed, single-hung, horizontal slider, casement, awning) and frame material. Large fixed lites and mulled units cost more than a standard punched window.

Performance class and grade

A CW or AW window costs more than an R or LC window of the same size. If the spec calls for a class and grade, we price that product. If it does not, we tell you what we are bidding and why.

Glass

Low-E coatings, tint, tempered or laminated safety glazing, obscure glass and matching an existing color each change the price per opening.

Access

Ground-floor openings from ladders cost the least. Upper floors, sloped grades and openings over landscaping or walkways may need a lift or scaffold, which is a line item.

Work hours and phasing

Work done early, late or on weekends, or split into many short phases so the building stays open, adds labor. The bid shows the schedule it assumes.

Takeoff or field measure

From drawings, we price from the window schedule and confirm every size in the field before ordering. Without drawings, we measure every opening on the walkthrough.

Finish work

Interior trim, exterior cladding or brick returns, flashing, sealant and any rotted framing found in the opening. Repairs found after tear-out are shown to you before we do them.

Our published residential price ($950 to $1,250 per window installed) is for houses. Commercial openings are bid separately.

Signs your commercial windows need replacing

Signs the Windows Are Costing You More Than They Save

  • Fog or film between the panes on more than a few units
  • Water stains, rotted sills or wet drywall below windows after rain
  • Sealant joints that are cracked, shrunk or pulling away from the frame
  • Aluminum frames that sweat or frost on cold mornings
  • Operable windows that no longer open, close or lock
  • Rooms that stay hot on sunny afternoons no matter where the thermostat is set
  • Cracked or unmarked glass beside doors or near the floor
  • Repeated glass replacement on the same elevation

What we need to bid commercial windows

Send These and We Can Price It

  • Building address and a contact who can open it for a walkthrough
  • Drawings, window schedule and specifications, if you have them
  • Number of openings, or the elevations involved
  • Photos of each elevation and a close-up of a typical window
  • Any required performance class, grade, U-factor or SHGC
  • Your schedule: start window, finish date, hours the building is open
  • Year built, and whether children under 6 use the building regularly
  • Bid due date and how you want it sent (owner, property manager or GC)

Commercial window installation process

From Walkthrough to Punch List

  1. Walkthrough or takeoff

    We walk the building with your facilities contact, or take off the window schedule from your drawings. We note access, work hours and anything the spec requires.

  2. Written bid

    Every opening is listed with its size, product and glass, plus access, phasing and exclusions, so you can compare it line for line with other bids.

  3. Submittals and order

    When your project calls for product data or shop drawings, we get them from the maker and send them for approval first. Windows are ordered only after sizes are confirmed in the field.

  4. Phased install and closeout

    Old windows out, openings repaired, new windows set, flashed and sealed, a few openings at a time. We walk the finished work with you, close the punch list and hand over warranty documents.

Commercial window replacement FAQ

What Building Owners and Facilities Managers Ask

How much does commercial window replacement cost?
Commercial window replacement is bid per project by Morgan Windows, priced opening by opening, because size, performance class, glass, access and work hours change the number more than they do on a house. We send a written bid that lists every opening, so you can compare it line for line. Our $950 to $1,250 per window price is for residential windows only.
Do you replace windows while the building is open?
Yes. Morgan Windows phases commercial window replacement so your building stays open, working a few rooms, a wing or an elevation at a time, and every opening is closed and weather-tight before the crew leaves. When a building cannot have work during business hours, early, late or weekend days are priced into the bid.
What is the difference between R, LC, CW and AW windows?
R, LC, CW and AW are the four performance classes in the North American Fenestration Standard, with minimum performance grades of 15, 25, 30 and 40. Higher classes are tested at larger sizes and higher pressures, and CW and AW add limits on frame deflection. The class is picked from the project's performance needs, and Morgan Windows bids whatever class and grade your spec calls for.
Can you bid commercial windows from drawings?
Yes. Morgan Windows prices commercial window packages from your drawings, window schedule and specifications, then confirms every size in the field before anything is ordered. Send the documents and your bid date, and the bid comes back with scope and exclusions in writing.
Do you replace church windows?
Yes. Morgan Windows replaces the clear windows in churches, including offices, classrooms, gyms and fellowship halls, and schedules around services and events. Stained and leaded glass repair belongs to a stained glass studio, and any protective glazing over it should be ventilated and set in its own frame, as the National Park Service recommends.
Do lead paint rules apply to replacing windows in a school or church?
They can. Under the EPA's Renovation, Repair and Painting Rule, replacing any window in a pre-1978 child-occupied facility is a renovation that must be done by a lead-safe certified firm. A building counts when the same child under 6 visits at least two days a week, at least 3 hours a day, 6 hours a week and 60 hours a year. Ask any contractor for the firm certificate before work starts.
Where is safety glass required in a commercial building?
Safety glass is required in the "hazardous locations" listed in IBC Section 2406: glass in doors, glass within 24 inches of a door edge with its bottom under 60 inches high, and large, low panes over 9 square feet near a walking surface. Morgan Windows checks each opening against these rules and orders marked safety glazing where they apply.
How long does a commercial window project take?
Most commercial window projects take a few days to a few weeks on site with Morgan Windows, depending on the number of openings, access and how the work is phased. Custom windows usually arrive about 2 to 4 weeks after order, and your bid states the lead time for the exact product.
What brands of commercial windows do you install?
Morgan Windows installs the manufacturer and product your architect or spec calls for, because we are not tied to one brand. When there is no spec, we bring options that meet the performance class, glass and budget the building needs.
