Texas Office Repainting: Build a Phased Estimate Around Occupied Rooms

1. Divide the office by operational boundaries

A floor plan tells you where the walls are. The office manager tells you when those walls can be reached. Ask which rooms can close together, which activities must continue and who can authorize release of each work area. Give each phase a room list rather than a label such as “half the office.”

These are scope groups, not a promise that each takes one night. Mark ceilings, trim, doors and excluded surfaces within each phase. Confirm that work-area isolation and required access routes can coexist before treating the sequence as agreed.

2. Convert building access into usable work time

Record badge collection, security check-in, loading access, elevator availability and the time the area must be handed back. A crew admitted at 6 p.m. may still need protection and setup before application can begin. Equipment and materials also need an approved place between visits.

Suppose two painters attend a five-hour window. That is 10 labor hours. If each spends 45 minutes on setup and 45 minutes on closeout, seven of the 10 hours remain for the intervening work: two people × 3.5 hours. The three other hours are still labor you must cost.

Ask who authorizes an overrun or a postponed phase if the room is not released. Keep that decision with a named building contact. Do not assume a vacant room, working badge and available elevator will all happen automatically.

3. Coordinate ventilation and equipment protection

EPA’s Building Air Quality Action Plan, Step 6 discusses lower-emitting products, lower-occupancy work periods and ventilation arrangements for painting. Use it to frame a conversation with the facility manager; it does not supply a universal overnight reopening time.

Confirm how the building’s ventilation will operate during and after the work, who controls it and whether other occupied areas are affected. In a Texas office with scheduled after-hours HVAC, verify the actual arrangement and any approved charges. An evening booking does not establish that suitable ventilation will be available.

Assign computers, monitors, network equipment and confidential materials to the customer’s designated staff unless your contract expressly includes their handling. State what your crew protects and what the customer must disconnect or relocate. Do not drape operating equipment or change building systems without the responsible facility team’s approval.

4. Measure and purchase by phase

Measure the actual included wall surfaces, subtract the openings you are excluding and record height changes. Keep a separate finish schedule for each color and sheen. Room floor area is not a substitute for wall area, especially where glazing occupies much of one partition.

For an illustrative office, assume the measured net walls total 1,800 sq ft across the three phases. Two coats at an invented coverage assumption of 350 sq ft per gallon require 1,800 × 2 ÷ 350 = 10.286 gallons. Eleven one-gallon containers would cover that calculation before additional reserve, assuming one compatible finish and color.

Verify the actual product’s coverage, coats and container sizes; multiple colors can require more purchases because each is rounded separately. Keep primer and repairs outside the finish-paint calculation. The wall measurement example shows the underlying takeoff method.

5. Price the repeated work and confirm Texas tax treatment

Use a phase-by-phase labor worksheet, then total the job. The following invented inputs include 60 labor hours of preparation and application plus 12 for repeated setup, protection changes and handoff. They are not local rates or a promised schedule.

At a test gross-margin target of 25%, $4,000 ÷ 0.75 = $5,333.33, rounded to cents. The $1,333.33 difference is before overhead and other expenses. See the margin calculation guide. Include real purchase taxes and other applicable costs in the input figures.

Texas Comptroller guidance treats nonresidential repair and remodeling as taxable and includes repainting, while distinguishing qualifying maintenance and other exceptions. Classify the actual contract before charging tax; do not copy residential treatment into an office quote. This example stops before any customer sales tax and does not determine the project’s classification.

6. Define the handoff for each phase

Make completion review a short, repeatable process. Confirm included surfaces, the agreed finish, protection removal and any documented touch-ups. Record remaining product-specific use or cleaning restrictions separately from the crew’s departure time.

• Building contact confirms the room group is available.
• Selected products and colors match the approved schedule.
• Facility team confirms the ventilation and equipment arrangements.
• Both parties record the phase’s condition and next release decision.

If the manager adds a room or requests a different sequence, use the scope-change process to show the effect on price and visits. Review the finished document with the contractor estimate checklist. The customer needs one proposal that connects surfaces, access, phases and payment terms.

Occupied office repainting questions

Is an after-hours quote just the normal price plus a surcharge?

Build it from the actual labor, repeated setup, access and coordination costs. A flat premium can miss restricted work windows or include costs the job does not have.

Does low-odor paint mean staff can immediately re-enter?

Do not promise that from a marketing label. Follow the selected product’s instructions and the building’s agreed ventilation and occupancy plan.

Should each phase receive a separate estimate?

One estimate can contain clearly identified phases and prices. Keep additions, billing stages and acceptance records tied to that same approved scope so work is not charged twice.
