How do I bid on a construction job correctly?

Bidding a residential remodel correctly is a skill that takes most contractors years to develop. Homeowners benefit from understanding what proper bidding looks like — it helps them evaluate bids and avoid lowball traps.

Proper bidding process (what good contractors do):

1. Complete drawings and specifications review — read every page. Identify ambiguities. Ask questions before bidding.

1. Site visit — see the actual conditions. Measure critical dimensions. Identify unique challenges (access, demo complexity, utility locations).

1. Scope of work checklist — itemize every trade, every deliverable. Nothing gets priced without being on the list.

1. Quantity takeoffs — count every square foot of flooring, every linear foot of baseboard, every receptacle, every light fixture.

1. Subcontractor bids — solicit from plumbing, electrical, HVAC, specialty trades. Verify each sub's scope matches yours. Include sub bids in total.

1. Material cost calculations — get current supplier quotes for major items (cabinets, counters, tile, fixtures). Assume 5-10% markup for material handling.

1. Labor cost calculations — hours per task × hourly rate (including burden: taxes, insurance, benefits). Typical framing carpenter burdened rate: $75-$125/hour depending on market.

8. Overhead and profit (OH&P): - Overhead: office costs, trucks, insurance, supervision not charged direct to jobs. Typically 10-20% of labor + materials. - Profit: owner compensation beyond overhead. Typically 10-15% on residential remodel.

1. Contingency — percentage for unknowns and risk. 5-15% depending on project type. Historic remodels and 1920s homes warrant higher contingency.

1. Permit and soft costs — include permit fees, architect fees if managing, engineering, surveys.

1. Review and cross-check — compare to similar past projects. Identify outliers.

Typical bid format (what homeowners should expect):

• Cover letter with scope summary.
• Detailed scope of work by trade.
• Allowance schedule (tile allowance $X/sqft, plumbing fixture allowance $X).
• Exclusions (what's NOT included).
• Draw schedule proposal.
• Timeline with major milestones.
• Assumptions and clarifications.
• Total contract price.
• Terms and conditions.

Red flags in bids:

• No detailed scope — just "kitchen remodel: $65,000."
• No allowances — "finishes included" usually means low-grade.
• Significantly lower than other bids — scope is missing.
• Significantly higher than other bids — may be accurate, or may be over-building risk.
• Missing trades — verify plumbing, electrical, HVAC all accounted for.
• No timeline.
• No exclusions list — means there's no clarity on what IS included.

Why lowball bids fail:

• Contractor misses key scope items; ends up at true cost via change orders.
• Contractor cuts corners on labor quality.
• Contractor uses cheaper materials.
• Contractor is in financial stress and may abandon if cash runs out.

What homeowners can do:

1. Get 3-5 bids from qualified contractors.
2. Reject the highest and lowest outliers unless there's clear reason.
3. Ask each bidder to walk through their line items.
4. Compare scopes side-by-side; identify what one included that another didn't.
5. Interview bidders in the middle of the range.

Pro perspective (if you're a contractor):

• Bidding is a cost of sales. Bidding too many jobs without winning wastes time.
• Win rates of 20-30% are healthy; higher win rates mean you're underpricing.
• Lose on price, win on value — compete on scope clarity, warranty, references, not lowest price.

AskBaily's matching process avoids the multi-bid treadmill — we route homeowners to one qualified, verified contractor who has visibility into project scope and pricing. Contractors get actual-fit leads instead of bidding 5 jobs to win 1. See /for-pros for the contractor-side framework.
