PRICING & ESTIMATING
How to price firestop jobs
Price a firestop job by identifying and measuring each condition, confirming the system and scope, and estimating materials, labor, equipment, access, and documentation. Add an appropriate allocation for overhead and a deliberate margin. A revenue scenario or a universal price per hole is not a substitute for that estimate.
Independent business education. Not project-specific installation instructions or a technical approval.
Two openings that look similar can have different systems, material requirements, access, and installation effort. A repeatable estimate records those differences and the assumptions behind them. It also identifies what you cannot price reliably until the project team supplies more information.
This guide provides a costing framework, not market rates or a bid for your project. All dollar figures below are invented solely to explain the arithmetic. They are not Wayne’s rates, Hilti product prices, typical job results, or a recommended margin.
Build a condition schedule
Group work by the construction, opening or joint, penetrating items, system reference, and access conditions. Count penetrations individually where appropriate and measure joints using a consistent unit. Record the location and document revisions so someone else can understand the takeoff.
Resolve missing ratings, unclear dimensions, and unmatched field conditions before treating them as a fixed-price installation. An allowance or unit rate needs a defined basis and an agreed process for variation; it should not conceal unresolved technical requirements.
Build costs from the actual work
Use current supplier quotes and your own measured production data where available. If you have no comparable data, make that uncertainty explicit and seek competent estimating help rather than copying an unsupported production rate.
- Materials: quantities for the selected systems, backing and accessories, supplier pricing, freight, and a reasoned waste allowance.
- Labor: a defensible time allowance for preparation, installation, handling, cleanup, and required records; include applicable employment costs.
- Access and mobilization: equipment, delivery, travel, setup, restricted hours, and the number of visits you have agreed to provide.
- Documentation and inspection coordination: submittals, logs, photos or labels when required, access for inspections, and closeout.
- Overhead: an appropriate allocation of business operating costs, without counting a project cost twice.
An illustrative estimate—not a price list
Imagine a clearly defined package with the following assumed costs. These are arbitrary amounts used only to demonstrate how to keep the estimate organized. The example omits project-specific taxes, financing, and risk allowances; add whatever your actual circumstances require.
| Cost category | Assumed amount |
|---|---|
| Specified materials and accessories | $600 |
| Installation labor, including preparation and cleanup | $900 |
| Project equipment and mobilization | $200 |
| Documentation and coordination labor | $100 |
| Allocated business overhead | $200 |
| Total costs included in this example | $2,000 |
Do not confuse markup with margin
Markup is measured against cost; margin is measured against the selling price. With the example’s $2,000 of included costs, a 25% markup produces a $2,500 selling price and a $500 remainder. That remainder is 20% of the selling price, not 25%.
To target a 25% margin against the same included costs, the illustrative selling price is about $2,666.67. The remaining $666.67 is not guaranteed take-home profit: any taxes, additional costs, financing, or overruns not included in the example still affect the result.
Define what costs your margin measure includes, then use it consistently. A sales markup, a job contribution margin, and after-tax business profit describe different things. Confirm the appropriate accounting treatment for your business.
Allow for coordination, uncertainty, and payment timing
A technically straightforward package can still require extra visits, waiting time, difficult access, or coordination before concealment. State the assumptions and follow the agreed change process when they no longer hold. Do not use an arbitrary contingency to avoid clarifying the scope.
Check payment milestones, retainage, material deposits, and the cost of carrying labor before payment. After completion, compare actual hours, consumption, visits, and administrative time with the estimate. Keep that information organized by comparable conditions for your next bid.
Use the bucket calculator for scenarios, not bids
The homepage calculator explores additional invoice revenue using your assumed invoice amount, number of suitable jobs, and add-on percentage. It does not count conditions, select systems, estimate product quantities, or subtract business costs.
Use it to frame a business conversation, then return to a project-specific takeoff and cost build-up before making a proposal. An annual scenario also assumes the same activity continues for twelve months; it is not a forecast of work you will win.
Frequently asked questions
- What is the standard price per firestop penetration?
- This site does not publish a universal price per penetration. A defensible unit price needs a defined condition, system, quantity, access, location, labor basis, and contract scope. A rate for one condition should not be applied to every opening.
- Is a 25% markup the same as a 25% margin?
- No. On $2,000 of included costs, a 25% markup gives a $2,500 selling price and a 20% margin against that price. A 25% target margin against those same included costs requires a selling price of about $2,666.67. These are arithmetic examples, not recommended rates.
- Does the calculator estimate my profit?
- No. It displays additional revenue before costs. It does not deduct materials, labor, rentals, overhead, taxes, or other expenses, and its example settings are not typical results or pricing advice.
