What Is a Fixed-Price Remodeling Contract? (A Homeowner's Guide)

A fixed-price contract is an agreement where the contractor commits to completing the defined scope of work for a set dollar amount. Unlike a cost-plus contract where the final cost is determined by actual expenses, a fixed-price contract gives the homeowner a known number before construction begins. The contractor agrees to deliver everything in the scope for that price. If their labor or material costs run higher than anticipated, that is the contractor's problem to manage, not the homeowner's.

Budget predictability is one of the biggest concerns homeowners have going into a remodel. Stories of projects that started at one price and ended at a much higher number are common, and they almost always involve one of two problems: either the contract was cost-plus, or it was technically fixed-price but the scope was so loosely defined that change orders filled in the gaps.

A well-structured fixed-price contract solves the first problem. A detailed scope of work attached to that contract solves the second. Together, they give the homeowner a reliable number to plan around and a clear standard to hold the contractor to.

• Material Cost Increases: If lumber, tile, or cabinets go up in price after the contract is signed, the contractor absorbs that difference in a true fixed-price agreement.

• Labor Overruns: If the work takes longer than the contractor estimated, their cost increases. Your price does not.

• Contractor Inefficiency: The contractor has a financial incentive to work efficiently because overruns come out of their margin, not your pocket.

• End-of-Project Surprises: With a fixed price and a detailed scope, there should be no unexplained additions to your final invoice.

No. Changes you initiate as the homeowner after the contract is signed are handled through change orders, which document the change and adjust the price accordingly. What a fixed-price contract protects you from is the contractor coming back mid-project to say that something they should have known about when they priced it is going to cost more. Legitimate unforeseen conditions, like discovering unexpected structural damage behind a wall, may warrant a change order. But those should be rare in a project that went through a thorough planning phase.

An estimate is a preliminary number based on incomplete information. It is subject to change and carries no contractual weight. A fixed-price contract is a legally binding commitment to deliver a defined scope for a defined price. Never confuse the two. If a contractor gives you an estimate and asks you to sign a contract, read the contract carefully to confirm it is actually fixed-price and not just cost-plus with an estimate attached.

Our fixed-price construction contract is signed only after the Planning and Design phase is complete. That means the scope is fully documented, materials are selected, and every trade has been accounted for before we commit to a price. The number you receive at the end of planning is not a range or an estimate. It is a defined construction price based on a real project. That sequence is what makes it actually fixed.
