What’s actually slowing this PC down?

Before you sign, make sure the contract spells out the work, materials, exclusions, total price, schedule, payment milestones, and process for approving changes. Confirm the contractor’s identity and qualifications, read the warranty and cancellation terms, and check your state and local requirements. A detailed written agreement should match the estimate and every promise you intend to rely on.
What should a home renovation contract include?
Read the contract alongside the estimate, plans, specifications, and product selections. The California Contractors State License Board (CSLB) sums up a thorough agreement this way: “A thorough contract tells how the work will be done, when it will be done, what materials will be used and how much it will cost.” Its guidance is specific to California, but the underlying questions help homeowners review a proposed scope anywhere.

Work, materials, and exclusions
Describe the work in enough detail that both sides can tell what is included. “Remodel kitchen” or “install cabinets” may leave important choices unresolved. Identify the rooms and tasks, products or materials, finishes, and any plans or specifications that define the job. CSLB gives the example of naming the particular cabinets rather than simply saying “install kitchen cabinets.”

If the contractor or homeowner is responsible for permits, say so and verify the requirement with local authorities. The FTC flags a contractor telling the homeowner to obtain required permits as a potential warning sign.
#1 Best Overall
Price and schedule
Check the full contract price against the estimate. Clarify whether it includes labor, materials, taxes, disposal, and any allowances or contingencies, and make sure the way the price is calculated is understandable. If the estimate and contract differ, ask for an explanation and a corrected written document before signing.
Include estimated start and completion dates, along with how schedule changes will be handled. Dates may be estimates rather than guarantees, so ask what circumstances can affect them and how you will be notified.
Payment milestones
Make the deposit, progress payments, and final payment terms clear. Each progress payment should be tied to an identifiable milestone rather than an arbitrary date; for larger jobs, the American Bar Association (ABA) advises planning payments after completion and approval of major phases. Do not pay the entire price before the work is complete. Deposit limits vary, and some states cap them, so check the applicable rule with your state or local consumer agency.
If financing is involved, review any separate loan or financing agreement on its own terms. The FTC advises against accepting a loan without understanding its terms and whether you can make the payments.
How to check the contractor and compare bids
Confirm who is signing
Check that the agreement names the actual contracting business and includes its address, phone number, and license information where required. Confirm who is authorized to sign for the company. Verify the license with the relevant state or county authority, and ask for proof of insurance. The FTC recommends considering only licensed and insured contractors.
Check references and available complaint information. Read reviews critically, and search the business name with terms such as “complaint” or “scam.” Get multiple written estimates and compare what each one includes, not just the headline price. Ask contractors to explain substantial price differences; the lowest estimate may reflect a narrower scope, different materials, or other assumptions.
Compare bids on matching assumptions
Use the same project scope as the basis for each comparison. Check named materials and product quality, exclusions and allowances, total price, schedule, payment milestones, permit responsibilities, warranty coverage, and contractor credentials. If one bid leaves a major item unclear, ask for a written clarification before treating the bids as comparable.
How should changes and promises be documented?
Any promise made in a conversation or call about scope, labor, materials, or cost should appear in the written agreement or an attached document. Do not rely on an oral assurance that conflicts with the signed terms.
Agree on a written change-order process before work begins. A change order should describe the requested work, its price and schedule effect, and who must approve it. Require approval before the extra work proceeds so the parties have a shared record of what changed and what it will cost.
What to review in warranties and dispute terms
Distinguish the contractor’s workmanship warranty from any manufacturer warranty covering products. For each, identify who is responsible, how long coverage lasts, what is excluded, how to make a claim, and any notice deadlines or required method for reporting a defect. A product warranty does not necessarily cover installation work, and a service contract is not automatically the same as a warranty.
Read the dispute provisions, including any required mediation or arbitration, and understand how they work before you sign. Some builder warranty arrangements offer or require mediation or arbitration. For a large, complicated, financed, or disputed project, consider having a local attorney review the proposed agreement; CSLB likewise notes that a homeowner may wish to review a contract with an attorney.

Cancellation rights and signing precautions
Read the entire agreement and every attachment. Fill in all blanks before signing, and do not sign a document you have not read or do not understand. Do not let a salesperson pressure you to sign immediately. The FTC identifies pressure, demands for full payment up front or cash only, and contractor-arranged financing as potential scam signals.
The FTC describes a three-business-day cancellation notice for qualifying contracts signed in the home or away from the seller’s permanent place of business. That period does not apply to every renovation contract; whether a cancellation right applies depends on the transaction and applicable law. Check the terms and local rules rather than assuming a universal cooling-off period.
If the salesperson spoke with you in a language other than English, ask whether local law entitles you to receive a translated copy before signing the English version.
Which rules depend on where you live?
Contract requirements, licensing, deposit limits, permits, cancellation rights, and language rules vary by state and locality. Federal Trade Commission guidance is a starting point, not a substitute for checking local requirements. For example, CSLB says written contracts are required for California home-improvement projects over $500 in combined labor and materials costs. That California threshold is not a nationwide rule.

If a problem later arises, the FTC suggests first trying to resolve it with the contractor and following phone conversations with a written letter. Keep notes and copies; if that does not resolve the issue, contact your state attorney general or local consumer protection office. USAGov’s state attorneys general directory and company complaint guidance explain where to start.
