What Colorado requires

  • Many cities license general contractors locally — Denver does through Community Planning and Development. Check your city's contractor lookup.
  • If plumbing is moved or added, the plumbing work must be done by a state-licensed plumber under DORA rules. Ask who that will be.
  • Most remodels that change plumbing, electrical or walls need a permit. Ask who pulls it and when inspections happen.

Before you hire: the checklist

  1. Look up the license (state or city) and match the name to the company on your quote.
  2. Get a certificate of insurance sent directly from their insurance agent, naming you as certificate holder.
  3. Get a written, itemized contract before any deposit.
  4. Confirm who pulls the permit and when inspections happen.
  5. Pay in stages, and ask for lien waivers from the contractor and major suppliers as you pay.
  6. Check confirmed past jobs — not just star ratings.
  7. For walk-in tubs and accessible showers, ask about the water heater capacity needed to fill the tub, door-seal warranty, and grab-bar blocking inside the wall.
  8. Get a line-item quote: demolition, materials, plumbing, electrical, permits and disposal listed separately.

Red flags

  • Cash-only, or a big payment before any work starts.
  • No written contract, or pressure to sign today.
  • Asks you to pull the permit yourself.
  • The license name doesn't match the business name on the quote.
  • Can't produce a current insurance certificate.

Questions homeowners ask

How do I check if a bath remodeler is legit in Colorado?

Check any license on the state or city lookup, ask for a current certificate of insurance, and look for customer-confirmed jobs. ProveHound shows all three with links and check dates.

Should I pay a bath remodeler up front?

Avoid paying in full up front. A reasonable deposit with the rest tied to milestones and final inspection protects you. Ask for lien waivers as you pay.

What should a bath remodeler quote include?

Scope, materials with brands and models, permits, timeline, payment schedule and warranty — all in writing.
