How to read a contractor agreement before a home renovation

Why Reading the Whole Contract Matters More Than You Think

Most homeowners skim a contractor agreement, sign it, and assume the price and start date are the only things that count. Then something goes wrong — a subcontractor damages a wall, the project runs six weeks over, or the contractor disappears after receiving a large deposit — and they discover the contract said almost nothing to protect them. Reading a renovation contract properly takes about an hour. That hour can save you thousands of dollars and months of frustration.

What follows is a systematic way to read and evaluate a contractor agreement before you sign.

Start With the Basics: Parties, Scope, and Dates

Who Is Actually Signing?

The contract should name the legal business entity doing the work — not just a person's name. "John Smith" is not the same as "Smith Construction LLC." If something goes wrong, you want to be able to hold a licensed, insured business entity accountable. Verify that the name on the contract matches the name on the contractor's license and insurance certificate. If they don't match, ask why before you go further.

Scope of Work

This is the most negotiated and most disputed section. Read it as if you know nothing about the project. Ask yourself: if a stranger read this, would they know exactly what is being built, installed, or replaced?

Vague language like "renovate kitchen as discussed" is a red flag. Good scope language specifies:

If the scope is vague, ask for a written revision before signing. Verbal assurances are nearly impossible to enforce.

Dates

Look for a start date and a substantial completion date — not just a rough timeline. Note whether the contract defines what "substantial completion" means (usually, the work is usable even if minor punch-list items remain). Also look for:

Payment Terms: The Section With the Most Leverage

Deposit Size

A deposit of 10–30% is standard for most residential projects. Be cautious about any contractor asking for more than 30% upfront, especially on a project over $10,000. Large upfront payments reduce your leverage if problems arise.

Draw Schedule

Payments after the deposit should be tied to specific milestones, not arbitrary dates. "Pay $5,000 on March 15" gives you no recourse if the work hasn't progressed. "Pay $5,000 upon completion of rough framing, verified by inspection" ties money to real progress.

Write down each milestone and ask yourself: is this milestone verifiable? Is there an objective way to confirm it's done before I release money?

Final Payment

The final payment — typically 10–15% of the total — is your most important leverage. The contract should state that the final payment is due only after:

If the contract asks for the final payment before these things happen, push back.

The Legal Sections Most People Skip

Lien Waivers and Mechanic's Liens

This is the most overlooked risk in home renovation. If your contractor doesn't pay their subcontractors or suppliers, those parties can file a mechanic's lien against your property — even if you paid the contractor in full. A lien can complicate or block a home sale.

The contract should require the contractor to provide conditional lien waivers with each payment request and unconditional lien waivers upon final payment. Ask for this language if it isn't there. In many states you can request lien waivers from subcontractors directly.

Insurance Requirements

The contract should reference — and you should separately verify — that the contractor carries:

Ask for a certificate of insurance naming you as an additional insured. Call the insurance company to confirm the policy is active. If a worker is injured on your property and the contractor has no workers' comp, you may face liability.

Change Order Process

Scope changes are inevitable on renovation projects. The contract should require that every change to scope or cost be documented in a written change order, signed by both parties, before work on that change begins.

If the contract is silent on change orders or allows verbal change orders, you are exposed. Contractors sometimes claim that requests you made in conversation added cost; if there's no written record, it becomes your word against theirs.

Dispute Resolution

Read this clause carefully. Some contracts require binding arbitration, which means you give up your right to sue in court. Arbitration can be faster and cheaper — but it can also favor repeat players (contractors) over one-time participants (homeowners). Know what you're agreeing to.

Also check whether the contract has an attorney's fees clause. Some contracts say the losing party pays the winner's legal fees; others are silent. This affects how practical it is to pursue a dispute.

Warranty and Workmanship Language

A good contract specifies a warranty period for labor — typically one year — during which the contractor will fix defects in workmanship at no charge. Materials may carry separate manufacturer warranties.

Look for:

Vague language like "contractor guarantees quality work" is not a warranty. It has no enforceable timeline or mechanism.

Permits and Inspections

The contract should clearly state who is responsible for pulling permits. In most jurisdictions, the contractor of record must pull the permit — and in most places, work done without a required permit can force you to tear it out or prevent a future sale.

If the contractor suggests skipping permits to save money, that should be disqualifying. Not only is it illegal in most cases, but unpermitted work can void homeowner's insurance claims.

Three Common Pitfalls to Flag Before You Sign

1. Missing or vague allowances. "Tile allowance: $3/sf" sounds specific, but if the tile you want costs $8/sf, you'll pay the difference out of pocket. Make sure allowances reflect what you actually intend to install.

2. No termination clause. What happens if you need to fire the contractor, or if the contractor abandons the job? The contract should specify how termination works, what notice is required, and how payment is settled for work completed.

3. Automatic dispute waiver language. Some contracts include language that says by accepting the final work, you waive all future claims. Read this carefully — it could prevent you from pursuing warranty claims later.

A Simple Review Checklist

Before signing, confirm the contract addresses all of the following:

FAQ

Should I hire a lawyer to review a renovation contract? For projects under $25,000, it's usually not cost-effective. Use the checklist above and request revisions in writing where needed. For larger projects or complex renovations (additions, full gut renovations), a one-hour consultation with a construction attorney is worth the cost.

Can I change the contract after I've signed it? Both parties can agree to modify a contract at any time, but changes must be in writing and signed by both parties to be enforceable. A verbal agreement to change terms is very difficult to prove.

What if the contractor refuses to add lien waiver language? That's a serious red flag. A reputable contractor should have no objection to providing lien waivers — it's standard practice. Refusal suggests either inexperience or that they're already anticipating not paying their subs.

Is a handshake deal or email exchange legally binding? In many jurisdictions, verbal contracts are technically enforceable for small amounts, but proving what was agreed is nearly impossible. Always insist on a written contract, regardless of how much you trust the contractor.

What if the contract is "the contractor's standard form"? Standard forms can be negotiated. Cross out language you don't agree with, initial the changes, and have the contractor do the same. Any term is negotiable until you both sign.
