How to include a subcontractor price in your quote
Your sub sent a price, and you need to turn it into a quote the homeowner can understand. Before you include a subcontractor price in your quote, give every exclusion an owner and a place in the document. This guide gives you a worksheet and wording you can use on the next proposal that lands in your inbox.
Their number is not your number until you have read what they left out. If you promise a finished room while their proposal excludes patching, painting, and debris removal, those tasks still need someone to do them. Copying the total alone can leave you carrying work you never priced.
Save the complete proposal. Then build the client quote from the included work, the missing work you will supply, and the work the client has agreed to keep outside your scope. Add markup after that review.
Read the scope before using a subcontractor price in your quote
Start with the actual proposal, including its last page and any referenced attachments. A total pasted from a text message does not tell you enough about the work behind it.
Check the address, rooms, drawing revision, quantities, materials, and finish selections. A proposal for the earlier layout may be perfectly clear and still be wrong for the quote you are writing now.
Read phrases such as “by others,” “owner supplied,” “existing conditions,” and “excluded” as unfinished assignments. Each needs a decision. For example, “fixtures by owner” leaves separate questions about purchasing, delivery, compatibility, and installation. Do not assume the sub meant all of them.
AIA’s instructions for its contractor-subcontractor agreement call for a precise scope, with references to relevant drawings, specifications, modifications, and accepted alternates. That is a useful standard for reviewing even a short residential proposal: identify exactly which work the price covers. AIA A401 instructions
Keep the source proposal unchanged in your job records. Use a separate worksheet for your decisions so you can distinguish what the sub offered from what you later promised the homeowner.
Give every exclusion somewhere to go
An exclusion from the sub’s price is not automatically an exclusion from your client quote. You may need that work to deliver the result you are selling.
Use this table while reading the proposal.
| What the proposal says | Decision to make | Where it goes |
|---|---|---|
| Work included in the sub total | Confirm it matches the current scope | Included trade work in your quote |
| Work excluded, but needed for your promised finish | Price it through your crew or another sub | Your own priced line or another priced trade line |
| Work the homeowner will arrange | Confirm responsibility and timing with the homeowner | Specific client-facing exclusion |
| Optional work the homeowner has not selected | Keep it outside the base total | Separately priced option, if you have a price |
| Work with an unclear boundary | Ask the sub to clarify | Hold the affected price until resolved |
| Hidden work that cannot yet be defined | State the known scope and the approval boundary | Written condition for assessing and pricing additional work |
“By others” is not a finished entry in your worksheet. Replace it with a named party: your crew, another subcontractor, or the homeowner.
If nobody owns a task needed for completion, the quote is unfinished. A general contingency does not resolve who will perform it, what finish they owe, or when they must arrive.
Also check for double counting. If your demolition line already includes debris removal, do not add it again because the trade proposal excludes hauling. Reference the existing line in your worksheet so the exclusion has a home without creating a second charge.
Worked pass: move one proposal into the client quote
The following is a scope exercise, not a sample trade price. Use the amounts from your actual proposal and your own estimate in the blank fields. No dollar figures or markup percentages are suggested here.
Assume you are reviewing a plumbing proposal for a bathroom remodel. For this example, the proposed scope includes the listed rough-in and fixture installation. Its exclusions are wall opening, wall repair, painting, debris hauling, fixture purchase, and replacement of concealed damaged piping outside the listed work. These are example terms, not a claim about what plumbers normally include.
First, record the sub total as S. Keep the proposal date and revision beside it. Do not change S to hide the extra work you are adding.
Next, decide what belongs in your bathroom scope. In this worked pass, your crew will open the walls, restore the agreed wall surfaces, paint those repaired surfaces, and haul the resulting debris. The homeowner will buy the agreed fixtures. Concealed damaged piping outside the listed work remains outside the base quote and needs a defined review and approval step.
| Entry from the example proposal | Your decision | Client quote treatment | Amount to enter |
|---|---|---|---|
| Listed plumbing work | Use the sub’s confirmed scope | Included plumbing line | S: actual sub total |
| Wall opening excluded | Your crew performs it | Separate wall-opening line | A: your estimated cost |
| Wall repair excluded | Your crew performs it | Separate wall-repair line | B: your estimated cost |
| Painting excluded | Your crew paints the agreed repaired surfaces | Separate painting line | C: your estimated cost |
| Debris hauling excluded | Your crew handles the specified debris | Separate hauling line | D: your estimated cost |
| Fixture purchase excluded | Homeowner purchases agreed fixtures | Exclusion with supply responsibilities | Outside this quoted total |
| Concealed damaged piping excluded | Assess if discovered; obtain approval before additional work | Specific exclusion and change boundary | Outside this base total |
| Contractor markup | Apply your chosen method to the stated cost base | Separate markup line in this worked quote | M: calculated markup amount |
Your worksheet’s cost subtotal is S + A + B + C + D. The quoted amount for this example package, before any applicable tax or separately stated charges, is that subtotal plus M.
Fill every amount with a supported estimate before sending. A blank does not mean zero. If wall repair will come from another sub, get that price rather than treating the work as free because you have not assigned it yet.
This is the same discipline used in how to estimate a remodel: identify the work, assign the cost, and keep uncertainty visible.
Copy the decisions into plain client wording
The worksheet is for you. The homeowner needs a clear description of what they are buying and what they must arrange.
Here is wording you can adapt for the worked pass. Replace every bracketed field before sending, and retain only statements that match the actual job.
Plumbing: Includes [specific rough-in work] and installation of [listed fixtures] in [named bathroom], based on [drawing or scope revision]. Wall opening: Includes opening [identified wall areas] to provide access for the listed plumbing work. Wall repair: Includes closing those openings and finishing the repaired surfaces to [specified finish]. Painting: Includes [specified preparation and paint coverage] on [identified surfaces]. Debris removal: Includes removal and disposal of debris generated by the wall-opening and repair work listed above. Homeowner-supplied fixtures: Fixture purchase is excluded. The homeowner will supply [fixture list], with models confirmed for compatibility before purchase and delivery required by [agreed milestone]. Installation of those agreed fixtures is included in the plumbing line. Concealed piping: Replacement of concealed damaged piping outside the listed plumbing scope is excluded from the base quote. If discovered, we will document the condition and provide the proposed additional scope, price, and schedule effect for written approval before performing that additional work. Contractor markup: [Amount], calculated on [identified cost subtotal].
Be specific about the finish boundary. “Patching included” leaves room for disagreement about sanding, texture, primer, and paint. Write the finish you priced.
If you exclude painting entirely, say who will arrange it and where your repair work stops. Do not describe the room as fully finished while leaving that boundary buried in an attachment.
Confirm unclear terms with the sub
Send a short clarification message before you commit to the homeowner. You can copy this version:
Subject: Scope confirmation for [job address] I am preparing the client quote from your proposal dated [date], revision [revision]. Please confirm that your total includes [specific listed work] and installation of [agreed homeowner-supplied fixtures]. I have wall opening, wall repair, painting, and the specified debris hauling assigned to my crew. Please confirm the access and wall-opening requirements you need before starting. Your proposal excludes concealed damaged piping outside the listed scope. Please confirm how you will report that condition and price any proposed additional work before proceeding. Please send a revised proposal if any of these points change your scope or total.
Keep the reply with the proposal. If the clarification changes the price or work, use the revised document as your source. A useful answer should settle the boundary, not merely say “looks good.”
Also confirm when the price expires and whether the sub’s schedule fits your planned sequence. Do not promise a start date based only on having received a price.
Add markup after you have priced the missing work
Markup belongs after scope review because the sub total may cover only part of the package you are selling. If you apply it to S and forget A through D, you still have unpriced work.
For the worked quote above, keep markup as a separate line. That lets you check the underlying cost subtotal and the amount added without blending them together. This example’s separate line is a way to show the calculation, not a claim that every quote must disclose the sub’s purchasing price.
Use the contractor markup vs margin guide for the math. Choose your own pricing method and cost base; do not borrow a percentage from this example.
Keep markup, tax, and any separately charged work distinct in your calculation. If a proposal leaves tax treatment unclear, resolve it before copying the total into your estimate.
Check the handoffs before sending
The remaining gaps often sit between two scopes. The sub needs access, your crew creates it, and someone must restore the surface afterward. Review those handoffs explicitly.
Read the completed quote against the source proposal once more. For each exclusion, point to its priced line, its existing scope line, or its explicit client-facing exclusion. Check that homeowner-supplied items have a delivery responsibility and that unfinished decisions have not slipped into a fixed total.
Then read it as the homeowner. They should be able to tell what room and finish the price delivers without decoding the sub’s shorthand.
