Posted by: KC Construction | Serving the Carolinas with Mold Remediation and Crawl Space Repair

Hey folks!

Mold is one of those problems that creeps up on homeowners and leads to a lot of uncertainty and one of the most common questions we hear is: “Can I get rid of mold myself?” It’s a fair question, and we thought it was time to start a transparent conversation about what you can do on your own and when it’s time to call a professional.

Short Answer: Yes, Sometimes But It Depends on the Severity​

If you catch mold early say, a small patch on your bathroom tile or under the sink you might be able to handle it yourself with proper precautions. But for larger infestations, hidden mold, or anything tied to moisture damage, it’s safer and more effective to bring in trained pros.

What We See in the Field at KC Construction​

Here’s what our mold remediation team typically encounters:

• 40% of our mold calls start with failed DIY attempts
• 70% of large mold growth is tied to crawl space moisture or poor ventilation
• 90% of homeowners underestimate the spread of hidden mold

We’ve been helping homeowners across the Carolinas for years, and if there’s one thing we’ve learned it’s that mold is sneaky, and DIY jobs often stop at the surface.

When DIY Might Be Enough​

Here’s when you might be able to remediate mold yourself:

The mold-affected area is less than 10 square feet
It’s not caused by ongoing leaks or crawl space moisture
You can see and access the entire mold patch
You’re using proper PPE (mask, gloves, goggles)
There’s no musty odor indicating hidden growth


Pro Tip: Use a solution of water + detergent (not bleach) to clean mold off hard, non-porous surfaces. And make sure the area dries completely after.

When to Call in the Pros (Like Us)​

You should bring in a professional mold remediation team like KC Construction if:

The mold covers a large area or keeps coming back
It’s inside walls, HVAC ducts, or crawl spaces
You smell musty odors but can’t see visible mold
There’s water damage, structural decay, or health symptoms involved
You're unsure of the mold type (some can be toxic)

We’ve seen DIY jobs that left mold hiding behind drywall or under floorboards causing more damage (and more expensive repairs) down the line.

Real-Life Example​

Case: Crawl Space Mold in Columbia, SC

A homeowner tried to clean surface mold using store-bought sprays. A month later, the musty odor came back stronger.

Our inspection revealed:

• High humidity in the crawl space
• Insulation soaked with moisture
• Mold spreading behind the vapor barrier

Solution: Full crawl space remediation, dehumidifier installation, and mold-resistant encapsulation. The odor disappeared, and air quality inside the home drastically improved.

Common Myths About DIY Mold Removal​

Myth 1: “Just spray bleach and you’re done.”
Reality: Bleach doesn’t penetrate porous surfaces, and can actually worsen mold problems.


Myth 2: “If I can’t see mold, it’s not there. "Reality: Mold often grows in hidden spaces
inside walls, attics, and crawl spaces.


Myth 3: “A fan will dry it out.”
Reality: Air movement can actually spread mold spores to new areas of your home.
