Clearance Testing & Certification in Colorado

Cleaning is not clearing

A property is not remediated because a crew was there for four days. It is remediated when post-decontamination samples come back under 0.5 µg/100 cm² and certification is issued. Everything before that is work in progress.

This matters commercially, not just legally. Without clearance documentation you will run into: lenders declining to finance, buyers walking or demanding enormous concessions, title companies flagging the file, insurers refusing to bind coverage, and — if the property was under a county health department order — the order simply staying open.

Why third-party clearance is worth paying for

A remediation contractor sampling their own work has an obvious conflict of interest, and sophisticated parties know it. Independent clearance testing by a separate certified consultant removes that objection entirely.

We include third-party clearance by default on every remediation, and we recommend you insist on it from any contractor you hire — including one that isn't us. If a company resists independent verification of their own work, that tells you something.

What clearance sampling covers

• All previously contaminated areas, sampled at defined 100 cm² locations
• HVAC returns, supply registers and plenum surfaces
• Areas adjacent to contamination, to verify nothing migrated during work
• Limited-exposure areas (attic, crawlspace) against the 4 µg/100 cm² threshold
• Previously painted or encapsulated surfaces against the 1.5 µg/100 cm² threshold
• Where P2P manufacturing occurred: iodine, lead and mercury vapor thresholds

Your certification package

On passing results you receive, as a single organized package:

• Baseline pre-remediation lab results
• The written remediation work plan
• Phase-by-phase photo documentation
• Hazardous waste disposal manifests
• Independent post-decontamination clearance lab results
• Written certification that the property meets 6 CCR 1014-3 cleanup standards

Hand this to a lender, an underwriter, a buyer's attorney or a health department and the conversation ends. Keep a copy permanently — it follows the property, and it is what converts a contaminated-history disclosure into a resolved one.

We also clear other contractors' work

If someone else did your remediation and you need independent clearance testing, we do that as a standalone service from $550. We will sample it honestly — which means if it fails, we tell you it failed and show you where.

If it does fail, you are in a much stronger position than you were an hour earlier: you have documentation to take back to the contractor who did the work, and a specific map of what they missed.

If a property fails clearance on our work

Clearance is a lab result, not a conversation — so we published exactly what happens when it goes the wrong way. This is the three-clean guarantee:

1. First clean — backed. We remediate, then independent clearance sampling decides whether it passed. No opinions, just the lab result.
2. Second clean — steeply discounted. If clearance fails on work we performed, we come back at a steep discount off the original price. We stand behind our primary remediation rather than charging you full freight to fix it.
3. Third clean — free, or minimum charge. If the first and second cleans both fail for any reason, we come out a third time free, or a minimum company charge based on room count and property size. At that point the problem is ours to solve, not yours to keep paying for.

It is also the reason we would rather over-scope HVAC on the front end than argue about it on the back end. A second visit costs us more than doing the ductwork properly the first time.
