Trade guide

Demolition & Disposal

Tearing out interiors, non-bearing walls and concrete, plus dumpsters and hauling. Careful demo protects what stays and finds hazards before they spread.

What the work involves

  • Protecting the rest of the home and controlling dust
  • Shutting off and capping utilities
  • Removing materials and sorting debris
  • Dumpster or haul-off
  • Leaving the area safe for the next trade

What should happen, step by step

Use this as a checklist while the job is underway. If a step is skipped, ask why.

Durations are typical planning ranges from Corky's field experience, not guarantees. Weather, inspections, material lead times and surprises behind walls change them.

How long it usually takes

Interior demo for a room is often a day or two. Concrete removal and larger tear-outs take longer, depending on equipment and disposal.

Plan your dates with the Project Timeline Planner

General guidance only. Your contractor's written schedule is what counts.

Inspections to expect

  • Usually part of the remodel permit
  • Asbestos notifications/abatement where required

Which inspections apply depends on your city or county. Ask your contractor to share each passed inspection result. Understanding permits & inspections

Payment schedule

Often part of the larger remodel payment schedule; standalone demo is usually paid on completion.

  • Pay a modest deposit, then progress payments tied to finished, visible milestones (e.g., 'rough-in passed inspection'), never to dates alone.
  • Keep payments at or behind the work completed - you should never have paid for much more than has been done and delivered.
  • Hold the final payment until the final inspection is passed, the punch list is finished and you have lien waivers.
  • Avoid cash. Pay by check or card so there is a record, and get a receipt for every payment.
  • Deposit limits vary by state: California, for example, caps a home improvement down payment at 10% of the price or $1,000, whichever is less. Arizona has no single statewide percentage cap that we are aware of, so negotiate it and put it in the contract. Check your state's rules.

Red flags & common rip-offs

  • Demolishing without testing for asbestos in older materials
  • Removing a wall without confirming it isn't load-bearing
  • No utility shutoffs
  • Debris left on site or dumped illegally
  • Surprise 'extra load' charges not in writing
  • Demo starts before testing in older homes

Also watch for the general warning signs: large upfront payments, cash-only, no written estimate, pressure to sign today and no proof of license or insurance.

Questions to ask before you sign

  1. Will you test for asbestos and lead first?
  2. How will you protect the rest of my home?
  3. Is the dumpster and disposal included, and what are the weight limits?
  4. What if you find damage behind the walls?
  5. Who confirms walls are non-bearing?
  6. Will you photograph anything unexpected before we decide how to fix it?

Get the answers in writing, in the contract. Always ask for the contractor's license number and proof of insurance, and check the license with your state or local licensing agency. How to hire a contractor · Quick question? Contractor's Desk ($5)

Warranty

Ask who pays if demo damages things that stay (floors, fixtures).

Expect two kinds of warranty: the manufacturer's product warranty (shingles, windows, fixtures, equipment) and the contractor's workmanship warranty on the installation. Get both in writing with the length, what is covered and how to make a claim. Many product warranties require registration or installation per the manufacturer's instructions. In Arizona, a homeowner can file a workmanship complaint against a licensed contractor with the Registrar of Contractors within two years of the last work performed on a remodel or repair.

DIY vs. hire out

Usually OK to DIY

  • Removing non-hazardous finishes (carpet, trim) in newer homes

Hire a licensed pro

  • Walls, anything with possible asbestos/lead, concrete, anything near utilities

Some work legally requires a licensed contractor and a permit even on your own home. Check your state and city rules.

Permits to expect

Demolition is often covered under the remodel permit; structural demo and some asbestos work require specific approvals and notifications. Permit rules are set by your city, county and state, so they vary a lot. Call or check the website of your local building department before work starts. When a permit is required, the licensed contractor usually pulls it in their own name.
