By L&K Environmental | Denver's Trusted Mold Inspection & Clearance Experts

If you’re a homeowner, contractor, or property manager in the Denver Metro area, chances are you’ve dealt with mold at some point — whether from a basement flood, roof leak, or winter ice damming. And if you’ve hired a mold remediation company, you might be shocked to learn that many Denver mold remediation projects fail their final clearance inspection.

At L&K Environmental, we specialize in third-party mold inspections and post-remediation clearance testing across Denver and the Front Range. We’re often the final checkpoint before a property can be restored or reoccupied — and we’ve seen firsthand why so many projects fail. The good news? With a little more attention to detail, most of these failures are completely avoidable.

What We Look for During Mold Clearance in Denver Homes and Properties

When we perform a mold clearance inspection in Denver, Lakewood, Aurora, Arvada, Highlands Ranch, or any surrounding suburb, we’re looking for more than just "no mold." A proper clearance inspection ensures the environment is clean, dry, and safe — for your family, your tenants, or your clients.

Here’s what our team checks for on every project:

• No visible dust or debris — Drywall dust, wood particles, screws or nails in studs all indicate incomplete cleaning.
  
  
• No visible mold or water staining — Especially on framing, subflooring, or joists. Stains can signal a lingering moisture issue or missed material.
  
  
• Fully sealed containment zones — We verify containment is intact with no airflow from neighboring units, basements, crawlspaces, or exterior sources like window wells.
  
  
• Dry conditions throughout — We use moisture meters to ensure previously wet materials (like sill plates and studs) are 100% dry.
  
  
• No leftover tools or trash — Anything left behind in containment is a red flag for quality control — and a potential contamination source.

Why Mold Clearance Fails So Often in Denver

‍

We get it — Denver is a fast-moving construction and renovation market. Whether it’s a house flip in Wheat Ridge or a basement rehab in Centennial, there’s pressure to get the job done fast.

But this rush is exactly what causes clearance failures.

Here’s what we commonly see in failed mold remediation projects around the Denver area:

• Drywall dust or debris left behind — Even small particles can cause failed air quality tests.
  
  
• Containment leaks — Gaps that allow air from nearby units, garages, or crawlspaces to mix with the cleaned area.
  
  
• Wet framing — Especially during winter or spring when drying conditions are slower.
  
  
• Cutting corners on protocol — If all water-damaged materials weren’t removed, mold can return quickly — even after a “cleaning.”
  
  

Clean, HEPA Vacuum, Repeat — The Formula for a Fast, Affordable Pass

‍

Here’s what we recommend to all Denver mold remediation contractors and DIY homeowners:

Clean thoroughly, HEPA vacuum, and repeat.

This simple, repeatable process may take a bit more time upfront, but it saves hours — even days — in the long run. Many companies rush the first clean, only to fail clearance and spend more time and money doing it all over again. It’s avoidable. We’ve seen it hundreds of times.
