How to write a contractor estimate
- Visit the job first. Measure, take photos and look for problems (water damage, peeling paint, rotten wood) before you give a price.
- List each part of the work on its own line. Labor, materials, prep work, cleanup. Clients trust estimates they can understand.
- Write the scope clearly. Say what is included (for example, "two coats on walls and ceilings") and what is not ("drywall repairs over 1 sq ft are extra").
- Set a deposit. Many contractors ask for 10% to 50% before starting, especially to buy materials. Check your state's rules: some limit how much you can ask upfront.
- Give the estimate an expiration date. Material prices change. 15 to 30 days is common.
- Ask the client to sign. A signed estimate shows the client agreed to the price and the scope before you started.
Estimate, quote or bid: what's the difference?
People use these words loosely. In general, an estimate is your best calculation of the cost and can change if the job changes. A quote is usually a fixed price for a defined job. A bid is the price you submit when a client or company is comparing several contractors. Whatever you call it, write down the scope and the conditions so there are no surprises.
Write it in Spanish, deliver it in English
Open the Spanish version of this tool and pick the job descriptions from the list: they appear in English on the estimate. The document labels (valid until, deposit required, client acceptance…) also follow the language you choose. Text you type yourself, like the scope of work, appears as written; you can choose "Both (English / Spanish)" so your client can read the main parts.
What to include in the scope of work
- The areas or rooms included, and the ones that are not.
- Materials: brand or quality level, and who buys them.
- Preparation and cleanup.
- Approximate start date and how long the job will take.
- How changes are handled ("extra work will be quoted separately before it is done").
- Payment schedule: deposit, progress payments and final payment.
- Warranty on your work, if you offer one.
Frequently asked questions
Is the estimate legally binding?
A signed estimate is evidence that the client agreed to the price and scope, but contract rules vary by state. For large jobs, many states require a written contract with specific terms. Check your state's contractor licensing board.
How much deposit should I ask for?
It depends on the job and your state. Deposits of 10% to 50% are common, and some states set a maximum for home improvement work. Enter the percentage and the estimate calculates the amount.
Can I turn the estimate into an invoice?
Yes. Your business details are shared between both tools on this device. When the job is done, open the invoice generator and add the final work and prices.
