About the people doing the work
- Do the technicians assigned to my job hold IICRC certification in mold remediation, and can I see it?
- Who will supervise on site, and will that person be there during removal?
- Do you carry general liability coverage, and can your insurer send me a certificate?
- Do you subcontract any part of the job, such as rebuild or HVAC work?
- How long have you worked in Douglas County, and do you schedule regularly in Highlands Ranch?
About the moisture source
- What do you believe caused this growth?
- How did you confirm it, with meter readings, thermal images or opening a wall?
- Is the source correction included in your scope, or do I hire it separately?
- If the source is a bath fan duct or a plumbing leak, who fixes it?

Comparing answers
A contractor who explains the source clearly, sizes containment to the job, and is comfortable with independent clearance testing is usually a stronger choice than one who leads with fear or with a single product. Be cautious if someone insists the whole house must be treated without having looked in most rooms, or pressures you to sign that day.
Ask each contractor the same questions and write their answers on the same sheet. Differences in scope matter more than differences in the final number, because a lower figure often reflects a smaller plan, not a better deal.
Common questions
Does Colorado license mold remediation contractors?
Colorado does not run a dedicated state mold license, which is why asking about training, insurance and references matters so much. Asbestos is a separate matter: if older materials such as some textured ceilings must be disturbed, Colorado requires state-certified asbestos professionals for regulated work. Check with CDPHE.
Is it a bad sign if a contractor will not give a number on the first visit?
Not necessarily. For hidden basement or wall problems, some contractors prefer to take readings, review photos and send a written scope a day or two later. That is often more reliable than a figure written on the spot.
