Why the Questions You Ask Before Signing Matter So Much

Hiring a contractor for a major home project — a kitchen remodel, a roof replacement, an addition — is one of the larger financial decisions most homeowners make outside of the purchase itself. Yet many people spend more time researching a new appliance than they do vetting the tradesperson who will be working inside their home for weeks or months.

The good news: a focused set of questions, asked before any contract is signed, can significantly reduce the risk of disputes, delays, and costly surprises. This guide lays out the questions that matter most and explains why each one earns its place on your list. For a broader look at getting a project ready to launch, see our guide on planning a home renovation.

Core Questions Every Homeowner Should Ask

The following practices represent the questions and checks that experienced homeowners and consumer protection agencies consistently recommend. Work through each one before you commit to any contractor, regardless of how the initial impression feels.

1

Verify license and insurance before any other conversation proceeds.

An unlicensed contractor cannot legally perform regulated work in most states, and an uninsured one exposes you to liability if a worker is injured on your property. Confirming both upfront filters out unqualified candidates immediately.

Example: Ask for the contractor's license number and verify it through your state's licensing board website. Request a certificate of insurance naming you as an additional insured, and call the insurer directly to confirm the policy is active.
2

Request references from at least three comparable recent projects and actually contact them.

References reveal patterns — consistent lateness, communication problems, or substandard finishes that a polished sales pitch will never surface. A contractor confident in their work will provide references willingly.

Example: Ask each reference specifically: Was the project completed on time and on budget? How did the contractor handle unexpected problems? Would you hire them again?
3

Require a written contract that details scope, materials, timeline, and payment terms.

Verbal agreements are nearly impossible to enforce. A detailed contract creates a shared record of expectations and gives both parties recourse if something goes wrong.

Example: The contract should list every major task, the specific materials to be used (including brand or grade where relevant), milestones tied to payment, the start date, and a projected completion date.
4

Ask explicitly who will be on-site doing the work — and who supervises subcontractors.

Many contractors win work themselves but delegate most of it to subcontractors you've never vetted. This isn't always a problem, but you deserve to know, and you should confirm that subcontractors are also properly licensed and insured.

Example: Ask: 'Will you personally be on-site daily, or will a crew lead be running the job? Are your subcontractors covered under your insurance policy or their own?'
5

Clarify the payment schedule and never pay the full amount upfront.

Paying in full before work is complete removes your primary form of leverage and is a hallmark of fraudulent operators. A reasonable deposit (commonly 10–30% depending on project size) is standard; subsequent payments should be tied to completed milestones.

Example: A typical payment structure might be: 20% at signing, 30% when framing is complete, 30% at rough inspections, and the final 20% after a satisfactory walkthrough and sign-off.
6

Confirm who is responsible for obtaining permits and scheduling inspections.

Unpermitted work can create serious problems when you sell your home, file an insurance claim, or need future repairs. In most jurisdictions, the contractor of record is responsible for pulling permits — but this should be explicit in your agreement.

Example: Ask: 'Will you obtain all required permits before work starts, and will you handle inspection scheduling?' If a contractor suggests skipping permits to save money, treat that as a significant warning sign.
7

Ask about the warranty on both workmanship and materials before you sign.

Problems with construction work often appear weeks or months after completion. Understanding what is covered, for how long, and how to make a claim protects you against defects that weren't visible at project close.

Example: A reputable contractor should offer at least a one-year workmanship warranty as standard. Separately, ask for documentation of manufacturers' warranties on major materials like roofing, windows, or flooring.

Red Flags to Watch For

Even with the right questions, a contractor's responses matter as much as the questions themselves. Watch for these warning signs during your conversations:

  • Pressure to decide immediately — a reputable contractor will give you time to compare bids and review a contract carefully.
  • Cash-only payment demands — this limits your dispute options and may signal an attempt to avoid a paper trail.
  • Vague or verbal-only scope descriptions — if a contractor resists putting specifics in writing, that reluctance will likely continue throughout the project.
  • Suggesting you skip permits — this puts legal and financial liability squarely on you as the homeowner.
  • Unusually low bids — a quote significantly below others often reflects missing scope, inferior materials, or unlicensed labor.

Permit Requirements Vary by Location

Licensing and permit rules differ significantly from state to state and even between municipalities. What requires a permit in one county may not in another. Always verify local requirements directly with your city or county building department before work begins. See our guide on planning a home renovation for more on this groundwork.

If you're financing your renovation through a personal loan or line of credit, review your borrowing terms with the same care you apply to your contractor contract. Our personal loan pre-application checklist can help you prepare.
