What Should You Put in Writing Before a Major Home Repair Begins?

You may have compared bids, checked references, and chosen the contractor who seems best suited to the repair. The estimate may list a price, a few materials, and an expected start date. That can feel like enough to move forward—especially when the roof, plumbing, structure, or another essential part of the home cannot wait.

But the document that helped you choose a contractor is not necessarily the agreement that will govern the project. Before demolition or material orders begin, the written record needs to explain what will be done, who is responsible for each task, when funds can be released, and what happens if the work does not follow the plan.

What turns an estimate into a project agreement?

The agreement should identify the parties, the property, the total price or pricing method, and all incorporated documents. Attach the final scope, drawings, product schedules, selections, allowances, exclusions, and any proposal you intend to control the work. If documents conflict, say which one prevails.^[1]

Describe the result precisely enough that completion can be observed. Name brands, model numbers, grades, dimensions, colors, installation standards, and who supplies each item where they matter. Identify what existing conditions are assumed, how concealed damage will be handled, and which work is expressly outside the price. An allowance is not a final price; state its amount, what it covers, and how an overage or unused balance will be treated.

The contract should also assign permits, inspections, debris removal, cleanup, protection, and restoration. Confirm required licensing and insurance separately, then make continuing coverage contractual responsibilities.^[2] Your own insurer should know about a major renovation because the work can change property and liability risks.^[3]

How should scheduling, access, and communication work?

Put the expected start, substantial-completion, and final-completion dates in writing, along with legitimate reasons dates may move and how delay notice must be given. Identify working hours, planned shutdowns, material lead times, and any phases during which kitchens, bathrooms, entrances, heating, cooling, water, or security will be unavailable.

Access deserves its own terms when you live alone. State who may enter, how keys or codes are controlled, whether subcontractors may be onsite without the contractor, which rooms are off-limits, and how the home will be secured each day. Name one contractor contact and the channel for routine updates, urgent damage, schedule changes, and decisions that need your approval.

A realistic schedule protects both sides better than a date that assumes nothing will change. The contract does not need to eliminate uncertainty. It needs to show how uncertainty becomes notice, a documented decision, and—when appropriate—an adjusted price or completion date.

What must happen before money moves?

How should payment and change orders be controlled?

Tie the deposit and progress payments to identifiable materials or observable milestones rather than calendar dates alone. State what evidence supports each invoice, how long you have to review it, what amount may be withheld for incomplete or defective work, and which payment methods are permitted. Deposit limits, lien rules, required notices, and waiver forms vary by state, so local counsel should review a material project before you sign.

Require appropriate lien releases from the contractor and, when applicable, from subcontractors and suppliers as payments are made. A release must fit the payment and applicable law; it is not merely a receipt.^[4] Final payment should wait for agreed completion evidence, correction of the punch list, warranties, permit closeout, and final releases.^[5]

Require every change to describe the revised work, price, and schedule effect before changed work begins. Standard construction practice treats a change order as a written modification of the existing agreement.^[6] Also identify any narrow emergency authority the contractor may have to prevent immediate property damage when you cannot be reached.

Dovetail Principle: A Plan Is Built on Decisions You Can Stand Behind

A repair agreement is not about distrusting the contractor or predicting every hidden condition. It is the record of the decisions you are willing to authorize: the intended result, the limits on access and spending, the evidence required for payment, and the path for changes or problems. When those decisions are visible before work begins, you are less likely to negotiate them while part of your home is already open.

What proves the project is complete?

Define substantial completion separately from final completion if you will begin using the space before every detail is finished. The completion package may include signed inspection approvals, photographs, test results, as-built information, product manuals, warranty documents, receipts, a corrected punch list, and confirmation that keys or codes have been returned or changed.

Write down the warranty period, what is covered, who responds, how a claim is submitted, and the deadline for correction. Add the process for notice of breach, an opportunity to cure when appropriate, suspension or termination, dispute resolution, attorneys’ fees if applicable, and the law or venue governing the contract. These terms deserve legal review because state law can change both the available remedies and the enforceability of the language.

Before authorizing work, read the agreement and every attachment as one document. You should be able to point to what will be built, who handles each operational responsibility, what unlocks each payment, how a change becomes authorized, and what proves the contractor has reached final completion. The estimate helped you select the contractor. The complete agreement should now govern performance and payment.
