How to Write a Scope of Work
That Prevents Disputes

Why Scopes Matter More Than Price

A handshake deal works until it doesn't. And it usually stops working right about the time the customer says "I assumed you were going to paint after you patched the drywall" or "Aren't you going to haul away the old materials?"

A written scope of work protects both you and the customer. It sets clear expectations, prevents misunderstandings, and gives you documentation if things go sideways.

What Every Scope Should Include

1. Detailed Description of Work

Be specific. Not "bathroom remodel" but:

• Demo existing tile in shower area (walls and floor)
• Install cement board backer on shower walls and floor
• Waterproof shower pan and walls with RedGard membrane
• Install 12x24 porcelain tile on shower walls (to ceiling height)
• Install 2x2 mosaic tile on shower floor with linear drain
• Install new shower valve (Moen Posi-Temp, chrome)
• Install frameless glass shower door (48" opening)

The more specific you are, the less room there is for "I thought that was included."

2. Materials and Specifications

Specify exactly what materials you're using:

• Tile: Daltile Exquisite 12x24, color "Chantilly White"
• Grout: Mapei Keracolor U, color "Silver"
• Fixture: Moen Posi-Temp valve, model T2152, chrome finish

If the customer wants to upgrade materials mid-job, you have a baseline to calculate the upcharge from.

3. Exclusions (This Is Critical)

The exclusions section is where you protect yourself. Explicitly list what you are NOT doing:

• Painting (by others)
• Electrical work beyond existing circuits
• Mold remediation if found behind existing tile
• Replacement of subfloor if rotted (will be quoted separately)
• Towel bars, toilet paper holder, and accessories (by others)
• Plumbing beyond shower valve and drain connection

Every item on this list is something a customer might reasonably assume is included. Spell it out.

4. Timeline and Schedule

• Estimated start date: [date]
• Estimated completion: 8-10 working days
• Working hours: Monday-Friday, 8am-5pm
• Access requirements: Bathroom must be cleared before start date

5. Payment Terms

• 50% deposit upon acceptance
• 25% at rough-in completion
• 25% at final completion
• Payment methods accepted: Check, Zelle, credit card (3% fee)

6. Change Order Process

This is the part most contractors skip and later regret:

"Any changes to this scope of work must be agreed upon in writing before work begins. Additional work will be quoted separately and requires written approval before proceeding. Verbal requests for changes are not binding."

Real Example: Electrical Panel Upgrade Scope

Here's what a complete scope looks like for a common job:

Scope of Work — 200 Amp Electrical Panel Upgrade

Included:

• Remove existing 100A panel and all breakers
• Install new 200A Square D Homeline panel (40-space)
• Install new 200A main breaker
• Re-land all existing circuits on new breakers
• Install new grounding electrode system (2 ground rods)
• Label all circuits at panel
• Pull required electrical permit
• Schedule and pass city inspection

Excluded:

• Meter base replacement (utility company responsibility)
• Any new circuits beyond existing
• AFCI/GFCI upgrades beyond what code requires for panel replacement
• Drywall repair if wall opening is required
• Service entrance cable replacement (if required, quoted separately)

Price: $2,400 | Timeline: 1 day | Payment: 50% deposit, 50% at completion

The Bottom Line

A good scope of work takes 10 extra minutes to write. It saves you hours of arguments, thousands in unpaid extras, and the stress of "he said, she said" disputes. Be detailed. Be explicit about exclusions. Get it in writing. Your future self will thank you.
