How to Write a Construction Contract That Actually Protects You

Most contractors have been burned by a job that went sideways — a customer who disputed the scope, refused to pay for extra work, or withheld final payment over a punch list item that had nothing to do with the original agreement. In almost every case, the root cause is the same: the contract wasn't specific enough.

A contract that says "install hardwood flooring in living room and hallway, $4,200" is not a contract. It's a number on a page. When the customer says "I thought that included the closets" or "I expected you to move the furniture," you have no protection.

What a real construction contract needs

A contract that protects you needs to answer these questions unambiguously:

**What exactly are you doing?** The scope of work should be specific enough that a stranger reading it could understand exactly what's included and what's not. "Install 800 sqft of LVP flooring in the living room, dining room, and hallway as shown on the attached floor plan. Includes subfloor preparation for areas within normal tolerance. Does not include furniture moving, removal of existing carpet, or installation in bedrooms." That's a scope. "Install flooring" is not.

**What are you not doing?** Exclusions are as important as inclusions. List them explicitly. Customers fill in gaps with assumptions, and their assumptions are almost always more favorable to them than to you. If you're not doing demo, say so. If you're not doing painting, say so. If subfloor repairs beyond a certain threshold are extra, say so.

**What does it cost and when is it due?** Payment terms should be specific: deposit amount, when the deposit is due, when the balance is due (upon completion, net 30, etc.), and what happens if payment is late. Include a late payment fee — even if you never enforce it, it signals that you take payment terms seriously.

**How are changes handled?** Every contract should include a change order clause stating that any changes to the scope of work must be agreed to in writing before the work is performed, and that the customer is responsible for the cost of approved changes. This is your protection against scope creep.

**What happens if there's a dispute?** Include a dispute resolution clause. Many contractors use binding arbitration rather than litigation — it's faster and cheaper. Specify the governing law (your state) and the venue.

The clauses most contractors forget

**Concealed conditions.** "If conditions are discovered during the work that were not visible or known at the time of this agreement and that materially affect the cost of the work, Contractor will notify Owner and provide a written change order before proceeding." This covers you when you open a wall and find mold, or tear off a roof and find rotted decking.

**Access and delays.** "Owner agrees to provide Contractor with reasonable access to the work area. Delays caused by Owner's failure to provide access, by other contractors, or by conditions beyond Contractor's control may result in additional charges and/or schedule adjustments." This covers you when the customer's other contractor is in the way or the customer isn't ready when they said they'd be.

**Substantial completion.** Define what "complete" means. "The work shall be considered substantially complete when all major scope items are finished and the space is usable for its intended purpose. Minor punch list items remaining at substantial completion do not entitle Owner to withhold payment." This prevents customers from holding final payment hostage over a missing outlet cover.

**Lien rights.** Include a notice that you have the right to file a mechanic's lien if payment is not received. In most states, you're required to provide this notice anyway — but having it in the contract makes it clear you know your rights.

Getting the contract signed before you start

A contract that isn't signed before work begins is a contract that may not be enforceable. Get the signature before you order materials, before you schedule the crew, and before you do any work on-site.

Electronic signatures are legally valid in all 50 states under the E-SIGN Act. There's no reason to require an in-person signature — it just creates friction and delays. Send the contract, get it signed electronically, and keep a copy.

How Vevvo handles contracts

Vevvo lets you send contracts for electronic signature directly from the platform — no DocuSign subscription, no PDF emailing back and forth. Your contract template is stored in the system, attached to the job, and the signed copy is saved automatically when the customer signs.

When a dispute arises six months later, you pull up the job in Vevvo and the signed contract is right there — along with the estimate, the change orders, the photos, and the invoice history. That's the paper trail that protects you.
