How to quote a construction job (without underpricing it)
Knowing how to quote a construction job is one of the most valuable skills a tradesperson has — and one of the least taught. A good quote does two jobs at once: it wins the work, and it protects your margin once the work starts. Get it right and the job is profitable and dispute-free. Get it wrong and you either lose the bid or win a job that costs you money. Here is a clear, repeatable way to do it.
Start with scope, not price
Before you put a number on anything, write down exactly what you are pricing. What is included, what is not, and what you are assuming. Most arguments about “extras” later come from a vague scope at the start. A specific scope (“remove and dispose of the old floor, supply and fit 24 m² of engineered oak, including underlay”) is worth more than any clever pricing trick.
Price labour at your real rate
The single biggest mistake is pricing labour at your wage. Your billable hourly rate has to cover much more than pay: overhead (van, tools, insurance, phone, software), the hours you cannot bill (travel, quoting, buying materials, admin), and a margin so the business can absorb surprises and grow. As a rule of thumb, only about 50–70% of your working hours are typically billable — so your rate has to carry the rest.
Build the number in layers
- Materials: list them with quantities and add a sensible waste allowance (often around 10%).
- Labour: realistic hours × your true hourly rate.
- Margin: your profit on top — not optional.
- Contingency: on renovation and older buildings, add a buffer for what you cannot see yet.
- Tax: show it separately so the customer sees the net price and the total.
Make it itemised, not a lump sum
A single lump-sum number invites the question “why so much?” An itemised quote answers it before it is asked. When the customer can see the materials, the labour, and the scope, the conversation shifts from “is this too expensive?” to “yes, that makes sense.” Itemised quotes typically convert better and lead to far fewer disputes.
Speed wins more than polish
Customers usually hire whoever replies clearly and first. A solid quote sent the same day often beats a beautiful one that lands a week later, when they have already signed with someone else. This is exactly where templates — and increasingly AI quoting tools — pay for themselves: they let you respond while the lead is still warm without cutting corners on accuracy.
Common quoting mistakes to avoid
- Copying a competitor’s price. Their costs and billable hours are not yours.
- Forgetting non-billable time. Travel and quoting have to be funded by the hours you can bill.
- No validity period. Material prices move — state how long the price holds.
- Vague scope. The cheapest way to lose money is an unclear “included vs. excluded”.
Quote faster, win more
Once you have a repeatable method, the bottleneck becomes time. Our tools help tradespeople turn a plain-language job description into a structured, itemised quote in minutes — you review and approve before anything is sent. See how the AI tools work or book a free demo.
Frequently asked questions
How do you quote a construction job?
Break the job into labour and materials, price labour at your true hourly rate (covering overhead and non-billable time, not just wages), add a margin, then state clearly what is included, what is excluded, and how long the price is valid. A written, itemised quote wins more work than a single lump-sum number because the customer can see what they are paying for.
What should a construction quote include?
A clear scope of work, an itemised breakdown of labour and materials, the total price (with tax shown separately), payment terms, a validity period, and any exclusions or assumptions. The more specific the scope, the fewer disputes about "extras" later.
How do I avoid underpricing a job?
Price labour at your real hourly rate, not your wage — it has to cover overhead, tools, insurance, and the hours you cannot bill (travel, quoting, buying materials). Add a contingency for unknowns on renovation work, and never copy a competitor’s price, because their costs are not yours.
How fast should I send a quote?
As fast as you can while staying accurate. Customers typically hire whoever replies clearly and first, so a same-day quote often beats a more polished one that arrives a week later. Templates and AI tools help you respond while the lead is still warm.
