How to Write a Service Contract for Repairs

Handshake deals cost contractors thousands of dollars every year. A client who “didn’t know” the price would go higher, or one who disputes the scope of work, or a job where what counts as “finished” was never defined — these disputes are almost entirely preventable with a written service contract.

This guide covers what a solid home repair service contract must include, how to write one, and a free template structure you can adapt for your business.

Why a Written Service Contract Matters

A written contract serves three functions:

1. Legal protection: If a dispute goes to small claims court or civil court, a written contract is your primary evidence. Without it, it’s your word against theirs.

2. Expectation alignment: Most contractor-client disputes aren’t about bad faith — they’re about different mental pictures of what was agreed. A contract forces both parties to see the same picture before work starts.

3. Professionalism signal: A contractor who shows up with a written contract is immediately more trustworthy than one who doesn’t. Clients who are serious about quality value this.

The 10 Must-Have Clauses

1. Parties and Date

Identify who is entering the agreement:

• Contractor name, business name, address, license number (if applicable), and contact info
• Client name and property address
• Date the contract is signed

2. Scope of Work

This is the most critical section. Be specific to the point of avoiding any ambiguity:

Bad: “Paint master bedroom” Good: “Apply two coats of client-provided Sherwin-Williams paint (color: Agreeable Gray SW 7029) to all four walls and ceiling of master bedroom (approx. 280 sq ft). Does not include trim, closet interior, or door painting.”

For repairs, include:

• What problem you’re addressing
• The specific materials you’ll use (brand, model, size where relevant)
• What the finished state will look like
• What is explicitly NOT included (to prevent scope creep disputes)

3. Project Timeline

• Start date: The date you’ll begin work (or the date you’ll contact them to schedule, if scheduling hasn’t been finalized)
• Estimated completion date: Honest estimate. Include a caveat for unforeseen conditions (“Completion is estimated at X business days from start, subject to conditions not visible until work begins”)
• Work hours: When your crew will be on site (this matters for homeowners with schedules or HOA restrictions)

4. Contract Price

State the total price clearly:

• Fixed price: “Total contract price: $X, inclusive of all labor and materials listed herein”
• Time and materials: “Billing at $X per hour labor plus materials at cost + X% markup. Estimated total: $X–$Y”

For fixed-price contracts, include a note about what triggers price changes (change orders — see clause 7).

5. Payment Schedule

Define payment milestones explicitly:

Example payment schedule:

• 20% deposit upon contract signing: $X
• 30% at project start (first day of work): $X
• 30% at midpoint milestone (e.g., rough-in complete, demo complete): $X
• 20% final payment upon completion and client acceptance: $X

Never accept 50%+ upfront for a job you haven’t started — it creates trust problems and, if something goes wrong, leaves you exposed.

6. Materials and Substitution

Specify:

• Who supplies materials (you or the client)
• Brand and model where relevant (especially for fixtures, hardware, appliances)
• What substitution policy applies if specified materials are unavailable: “If specified materials are unavailable, Contractor will notify Client and obtain written approval before substituting comparable materials of equal or better quality”

7. Change Order Process

Changes to scope are inevitable on real jobs. Define the process:

“Any changes to the scope of work described in this Agreement must be documented in a written Change Order signed by both parties before additional work begins. Change Orders will include: description of additional or modified work, price adjustment, and any timeline impact. Work performed without an approved Change Order will not be compensable.”

This single clause prevents more disputes than any other part of the contract.

8. Warranty and Defects

State your workmanship warranty explicitly:

• “Contractor warrants all work against defects in workmanship for [1 year / 2 years] from date of completion”
• “Manufacturer’s warranties on materials and fixtures are separate from this workmanship warranty and are the manufacturer’s responsibility”
• “Warranty is void if work is modified by parties other than Contractor”

9. Dispute Resolution

Many contractors add a clause specifying how disputes will be resolved:

• Mediation first, before litigation
• Jurisdiction (the county where disputes will be filed, if they go to court)
• Attorney’s fees provision (the losing party pays — this provision is standard in Texas contracts)

10. Signatures

Both parties sign and date. Digital signatures (via DocuSign, HelloSign, or similar) are legally valid in Texas under the E-SIGN Act.

Client Communication Around the Contract

How you present the contract matters as much as what it contains:

• Present it as standard practice: “Here’s my standard agreement for this scope of work” — not as a sign of distrust
• Walk them through it: Briefly explain the scope, payment schedule, and change order process. Clients who feel rushed through a contract are more likely to dispute later.
• Get signatures before starting: No work begins without a signed contract. This is non-negotiable.

Frequently Asked Questions

Do I legally need a written contract for home repair work in Texas?

Texas law does not require a written contract for most residential repair work. However, Texas does require written contracts for home improvement loans, certain roofing work over $1,000, and some other specific situations under the Texas Property Code. More importantly, without a written contract, you lose most of your practical legal protection if a dispute arises. Always use written contracts.

What should I do if a client refuses to sign a contract?

A client who refuses to sign a basic service agreement is a red flag. Legitimate clients who have hired contractors before understand and expect written agreements. If someone insists on a handshake deal, ask why — the answer is usually revealing. If they won’t sign, you have two options: walk away (usually the right call on larger jobs) or assess the specific risk and decide whether to proceed with a written document signed only by you (detailing your understanding of the scope).

How do change orders protect me as a contractor?

Change orders protect you by documenting additional scope in writing before you perform the work. Without a signed change order, a client can legitimately claim they didn’t authorize additional work and refuse to pay for it. Courts typically rule in favor of clients on undocumented scope changes. A consistent change order process also prevents scope creep — where small additions accumulate into significant unpaid work.

Should I use a contract template or hire a lawyer to draft one?

For most residential repair work, a well-drafted template adapted to your specific services is sufficient. Many state contractor associations offer contract templates. For larger projects ($50,000+) or commercial work, having a Texas construction attorney review your template is worth the investment — perhaps $200–$500 for a review. An attorney can also catch state-specific legal requirements you may have missed.

What happens if a client doesn’t pay after the job is complete?

Your first step is a formal written demand (certified mail). If that fails, Texas law provides contractors with mechanics lien rights — the ability to file a lien on the property if you haven’t been paid for work performed. Texas has strict notice and timeline requirements for filing liens (notice must be sent to the owner and any lenders within specific deadlines). A Texas construction attorney can walk you through the mechanics lien process for unpaid work. For smaller amounts, small claims court (up to $20,000 in Texas) is a faster and cheaper option.
