How the scorecards work

Each number comes from public Google data on the date shown. Rating is the live Google star average. Review volume is how many customers have rated the business, compared with other Denver mold and restoration firms. Confidence weighs the rating by that volume, so a 4.9 from hundreds of people counts for more than a 5.0 from a few. Recency reflects how lately customers are still leaving reviews. No business can pay to change these numbers.

What drives mold removal pricing in Denver (2026)

Reviewers on this page describe prices as reasonable for some jobs and higher for others, and none of them name a price for mold work alone. The size of the affected area, whether testing comes first, how much drywall or carpet must be torn out, and whether you need a whole-home treatment all move the quote. Ask each firm for an itemized written estimate.

Mold help across the Denver area

The firms here work from Denver, with Pure Maintenance of Colorado based in Arvada and serving the Denver metro and northern Colorado. If you’re searching for mold removal near me, each listing shows a phone number and directions so you can call the closest option.

Questions to ask before you book mold work

  • Do you test for mold yourselves, or work from a separate inspector’s report?
  • Will you fix the water source or only the mold, and who covers the rebuild afterward?
  • How will you contain the work area so spores don’t spread to the rest of the house?
  • Will there be a clearance test when you finish, and who performs it?
  • Can I have an itemized written estimate that separates drying, mold removal and repairs?

Frequently asked questions

Should the company that tests for mold also be the one to remove it?

Reviews on this page show both routes. One Pure Maintenance of Colorado reviewer worried about a conflict of interest, interviewed two other firms, and still hired Pure for the remediation after its testing. Another reviewer said an independent inspector had missed mold that Pure later found. Ask any firm whether it tests, whether it also removes, and how it keeps those two roles honest.

Do these Denver firms also deal with the leak that caused the mold?

Google lists every firm on this page as a water damage restoration service, and their sites or reviews cover water extraction and drying along with mold. Colorado Cleanup Services and Water Damage, Inc. both list water, fire, sewage and mold on their sites.

Does it matter that Pure Maintenance of Colorado is in Arvada?

Its site says it serves the Denver metro and northern Colorado, and its reviewers describe whole-home jobs in the area. Its listed hours are Monday to Friday, so ask about scheduling if the problem can’t wait for a weekday.

Will insurance cover mold cleanup after a leak?

That depends on your policy and the cause of the water, so ask your insurer. Reviewers of Colorado Cleanup Services and Restoration 1 of Central Denver say those teams worked with their insurance companies, while one Restoration 1 customer chose to pay out of pocket.

Where to start

Call Colorado Cleanup Services first if mold followed a flood and you want a large, busy crew, or Pure Maintenance of Colorado if testing and a full remediation plan come first. Whoever you pick, get the mold scope, the testing plan and the rebuild split out in writing.
