Rule of thumb: A remodel or addition quote is never an emergency.
The full list, in the guide's words

Safety first: If a ceiling, floor or wall is sagging, cracking or leaning, or water is getting into the structure, move people out of the area and get a pro out right away. Call 911 if anyone is in danger.

Emergency: call now

  • A sagging ceiling or floor, a failed beam or support, a leaning wall, or a deck pulling away from the house
  • Water getting into the structure: an open roof in rain, a flooding basement, a burst pipe behind new work
  • Storm or tree damage that leaves the home open to the weather

Within a day or two

  • A stalled active project
  • A failed inspection that blocks the next step
  • A leak at a new window, door or flashing with no structural risk

Can wait: schedule it

  • Quotes for remodels, additions and basement finishing, and design questions
  • Punch-list and warranty callbacks, and material and timeline questions

This is general guidance, not a diagnosis. If anyone is in danger, call 911 first.

Know what you're looking at

Red flags

4 of 12

  • A one-paragraph scope

    It should list what's in, finishes, what's out.

  • Money ahead of finished work

    Payments should follow completed stages.

  • No written change orders

    Extras agreed out loud get billed later.

  • Work before the permit

    Ask to see the permit before work starts.

8 more red flags

  • Not saying how subcontractors and suppliers get paid, or not offering lien waivers when you pay.

  • Pressure to sign today, or a price that is only good right now.

    A fair quote is still fair tomorrow.

  • No written quote, or a quote that is a single total with no detail about what is included.

  • A large payment up front, or a request for cash only.

    Some states limit how much a contractor can ask for before work starts.

  • A license number that does not check out.

    Where your state licenses this trade, look the number up yourself on the state licensing board's site.

  • No proof of insurance.

    Ask for a certificate sent to you directly by the insurer or the agent.

  • A price far below every other quote, followed by extras once the work has started.

  • Someone who knocks on your door uninvited, or who will not give recent local references.

Where homeowners say it goes wrong

  • No-shows for scheduled estimate appointments
  • Projects that blow past the timeline with no communication
  • Surprise costs and change-order sticker shock with no upfront clarity
  • Fear of getting scammed, abandoned mid-project, or hit with a lien
  • Vague quotes with no detail on scope, materials, or what's included

Ask every contractor

  1. What is in the written scope, which items are allowances, and what do you assume for each one?

  2. What is the payment schedule, tied to which finished stages, and will I get lien waivers with each payment?

  3. Who is on site each day, which parts does your own crew do versus subcontractors, and how do you handle changes and delays?

2 more questions

  1. Are you licensed where this work requires it, and insured? Can I see the license number and a certificate of insurance sent to me by your insurer?

  2. What exactly does the warranty cover, for how long, and who honors it (you, the manufacturer, or both)? Will you put it in writing?

Permits

Work like this usually needs a permit.

Remodels, additions, structural changes and most plumbing and electrical changes are commonly permitted and inspected. Additions and conversions typically end with a final sign-off or certificate of occupancy.

  • Your building department decides what applies at your address. Rules differ by city and county, and HOA, condo or historic-district rules can add more.
  • Ask who pulls the permit. Normally the licensed contractor does and the price includes it. If a contractor asks you to pull it in your own name, ask why: it can shift responsibility for the work to you.
  • If you are unsure, call your local building department before you sign. Unpermitted work can cause problems with insurance and when you sell.

Paying for it

Before you finance anything6 basics, then the financing guide

Most home projects can be paid in cash or financed. A few basics before you sign anything:

  • Ask for the cash price and the financed price in writing, for the same scope of work. They can differ, because a financing fee (sometimes called a dealer fee) may be built into the financed price.
  • Compare the total you will pay over the whole loan, not just the monthly payment.
  • Read the fine print on same-as-cash and zero-interest offers, especially what happens if the balance is not paid in full by the end of the promotional period.
  • PACE financing is repaid through your property tax bill and can place a lien on your home. Read the terms closely, and consider asking your mortgage servicer how it is treated, before you agree.
  • Utility and state programs sometimes offer low-rate loans for efficiency work. Check yours before accepting the contractor's offer.
  • Take loan paperwork home and read it. A sign-it-today loan is a reason to slow down.
