To quote a construction job, start with a site walkthrough, create a material takeoff, estimate labour hours, and then factor in overhead. Afterward, add a fair markup to cover your profit margin. Remember to account for pricing volatility with change-order clauses.

Pricing anxiety is common for new tradespeople. If you quote too low, you risk looking inexperienced, or worse, operating at a loss. Give a price too high and your clients might walk away. 

Knowing how to quote construction jobs isn’t just about being confident. You need to calculate materials, estimate labour, cover overhead costs, and apply the right profit margin formulas. Set quotes that reflect your value and keep your construction company growing. 

Start With a Site Walkthrough

The site walkthrough is a pre-estimate visit where you inspect the physical job site before preparing a quote. As a tradesperson, you’re assessing the feasibility of the proposed work based on site conditions, access, and client expectations. It’s a good opportunity to mention potential roadblocks, adjustments, additional steps, or calculate possible unexpected expenses that might come up during execution.

The walkthrough affects your final quote by:

  • Confirming that measurements and layout match the blueprints or drawings
  • Flagging potential labour or material overages
  • Identify potential unexpected costs like equipment access or weather protection

Document your visit with notes and photos. They’re useful for scope review, planning, and pricing justification.

Material Takeoff

Material Takeoff (MTO) is the process of listing and quantifying the raw materials required to complete a construction job. The name implies you’re “taking off” materials from blueprints line by line. Create a cost estimate detailing sheet count, length, or volume for lumber and drywall.

Your MTO will become the foundation for your overhead construction estimate. You need an accurate, specific reference to order the right quantities from suppliers, avoid waste overruns, and justify material costs. Otherwise, you’ll be left guessing figures.

Here are the best practices for making a more accurate material takeoff:

  • Pull quantities from blueprints or on-site measurements.
  • Use tools, spreadsheets, or construction job price calculators to streamline the estimating process.
  • Keep track of supplier variations in cost.

Flag lead times or delivery issues. Some items take longer to arrive, so make sure to manage client expectations. Additionally, account for pricing volatility. Material costs, especially lumber, drywall, copper, and steel, can fluctuate weekly based on demand and supply chain issues. Check with multiple suppliers and consider adding a buffer or clause for material price adjustments, especially for long-term construction projects.

Estimate Labour Hours

After the site walkthrough and material takeoff, begin estimating labor costs by calculating the work hours for each task. To determine a reasonable, accurate estimate, account for the following: 

  • crew size
  • skill level
  • task complexity
  • site conditions

Labour is a variable factor in estimates, influenced by project scope, crew size, and task complexity. Accurate hour estimation is important for profit and managing client expectations for detailed breakdowns.

Here’s how to set fair, reasonable timelines while maintaining profit margins:

  • Factor in site-specific delays. Tight access, limited power, or weather can hinder crew movement.
  • Account for learning curves. Adjust timelines for new hires or apprentices as they may need more time. 
  • Use unit productivity rates. Typically, installation takes one hour per 100 square feet of drywall or 30 minutes per outlet box, then scale by quantity.
  • Reference time logs from similar jobs in the past. Old time sheets reveal workflow factors; use them to estimate labour accurately.

Always inform clients of any changes in estimates to avoid them feeling blindsided.

Add Overhead Construction Costs

Your MTO includes direct project costs but excludes business overhead, which you must calculate to maintain profitability. This refers to the indirect, additional costs not tied to a specific project’s scope, which include what you pay for:

  • insurance premiums
  • fuel
  • phone bills
  • tool wear-and-tear
  • employees

These figures don’t need to be explicitly indicated in your estimate. Build them into your pricing structure as a percentage of your total job cost. Here are some best practices when making computations:

  • Track all recurring business expenses, including rent, insurance, phone bills, software subscriptions, and ad spend.
  • Log job-specific overhead separately when applicable. If you leased a piece of equipment solely for one job, record it under that project. It’ll keep you from inflating your overhead.
  • Calculate your break-even rate by dividing total monthly overhead by billable hours.
  • Review and adjust rates quarterly as your costs change over time.
  • Factor in tool depreciation and future equipment upgrades.

Pro Tip: Record everything, from recurring bills to one-off fees. The more accurate your records, the easier it is to quote jobs accurately and stay profitable long-term.

Apply Margin vs. Markup

As a construction business owner, knowing the difference between margins and markups is crucial. Margin refers to the profit you keep from the selling price. Meanwhile, the markup is the rate at which you increase your costs to determine the selling price.

Here’s how you can get the final price you charge the client:

  1. Start with your Material Takeoff total (e.g., $1,800).
  2. Add your labour cost estimate (e.g., $2,500).
  3. Factor in overhead as a percentage (e.g., 15% of the combined total).
  4. Apply markup to reach your target profit margin.
Category Cost
Materials $1,800
Labour $2,500
Overhead (15%) $645
Subtotal $4,945
Markup (25%) $1,236.25
Final Estimate $6,181.25

FAQs About How to Quote Small Construction Jobs

A quote is a formal offer given after the tradesperson and client have reviewed the job scope. It protects both you and the other party from miscommunication. It sets clear pricing expectations before work starts to prevent scope creep, payment delays, and, in some cases, legal disputes.

Several factors affect labour cost when setting construction quotes. Factor in your crew’s size, individual hourly rates, the estimated hours to perform each task, and the contingency buffer. Compute the labour burden, including indirect costs like WSIB premiums (in Ontario), insurance, benefits, and payroll taxes, which can cost around 20% to 40% of base wage.

Before delivering a quote for construction work, you need to prepare specific technical details. Conduct a site walkthrough, do a material takeoff, estimate labour hours, adjust the timeline, determine the payment terms, compute reasonable profit margins, and secure financing considerations. This gives clients a clear breakdown while protecting your bottom line.

In Summary

  • Start with a site walkthrough to assess access, layout, and scope before quoting.
  • Do a material takeoff to list, count, and cost every item needed from your blueprints.
  • Estimate labour hours based on crew size, task complexity, and past job data.
  • Consider insurance, fuel, and tool depreciation in pricing.
  • Understand margin vs. markup to calculate a price that reflects value.
  • Account for unforeseen circumstances and pricing volatility by adding buffers.
