The Estimate Checklist: What to Include in Every Bid

You walk the job, picture it in your head, throw a number together, and send it off. Two weeks into the project you realize you forgot to account for demo, disposal, the permit, and the three trips to the supply house. Sound familiar?

A complete estimate isn't just about looking professional — it's about protecting yourself. Every line item you miss is money coming straight out of your pocket. This checklist covers every category you should review before sending a bid. If you need the pricing formula behind the numbers, start with how to price a job.

Materials

• Primary materials — lumber, drywall, tile, fixtures, wire, pipe, concrete, roofing, paint.
• Waste factor — 10% minimum, 15% for tile and hardwood, 20% for trim and specialty cuts.
• Fasteners, adhesives, connectors, hangers, and brackets.
• Consumables — blades, sandpaper, drill bits, caulk, tape, drop cloths, cleaning supplies.
• Specialty items with long lead times — windows, cabinets, custom fixtures, special-order tile.
• Delivery charges, fuel surcharges, and minimum-order fees.
• Volatility buffer — 2-4% on materials prone to price swings before purchase.

Labor

• Actual work hours — be honest, not optimistic.
• Setup and cleanup time every day.
• Drive time to and from the job.
• Time for material runs and supply-house visits.
• Subcontractor labor plus coordination time.
• Inspection wait times and re-inspections if applicable.
• Punch list and callback buffer — 1-2% of labor.

Site Work and Prep

• Demolition and removal of existing materials.
• Dump fees, dumpster rental, and disposal costs.
• Site protection — drop cloths, plastic sheeting, floor protection, corner guards.
• Moving or covering furniture and belongings.
• Temporary supports, shoring, or bracing.
• Dust barriers and containment for occupied homes.
• Tree or shrub protection, driveway protection, sidewalk protection.

Permits and Compliance

• Building permits — include the fee and the time to pull it.
• Inspection fees and re-inspection fees.
• HOA approval requirements and timelines.
• Code-required upgrades discovered during work.
• Engineering or architectural drawings if required.

Logistics and Overhead

• Dumpster or trailer rental.
• Equipment rental — scaffolding, lifts, compactors, generators, specialty tools.
• Portable toilet for multi-day jobs.
• Parking and access fees.
• Insurance cost allocation.
• Temporary power, water, or heat.

Subcontractors and Suppliers

• Sub quotes — electrical, plumbing, HVAC, roofing, concrete, flooring.
• Sub markup for coordination, liability, and scheduling.
• Supplier backup — who is the alternate if your primary is out of stock?
• Lien waiver process and payment terms.

Project Closeout

• Final cleanup and debris removal.
• Touch-up materials and time.
• Client walkthrough and punch list time.
• Warranty callback buffer — 1-2% of total.
• Final photos or documentation.

What to Exclude (and Say So)

A strong estimate says what's not included just as clearly as what is. This is your shield against scope creep and disputes. List exclusions like:

• Permit fees if the homeowner is pulling the permit.
• Structural repairs not visible during the walkthrough.
• Mold, asbestos, or lead remediation.
• Moving furniture or storing belongings.
• Landscaping, paving, or work outside the defined area.
• Owner-supplied materials that you are not responsible for.

The Pre-Send Checklist

Before you hit send on any bid, run through these final questions:

1. Did I include waste and consumables, not just the big-ticket items?
2. Did I account for setup, cleanup, and drive time?
3. Did I include overhead and profit as separate line items or loaded rates?
4. Did I list what's not included?
5. Did I set an expiration date for the proposal?
6. Did I specify deposit and payment terms?
7. Did I include a change-order clause?
8. Would another contractor looking at this bid question any number?

The Bottom Line

Print this checklist out. Tape it to your dashboard. Run through it before you send every single estimate. The five minutes it takes will save you hundreds — or thousands — on every job. And once the estimate is done, make sure you protect the scope with a written change order process so those numbers don't get eaten by 'while you're here' requests.
