Why Fall Is a Smart Time to Check Your Crawlspace for Mold & Moisture in Western North Carolina

As temperatures begin to cool across Morganton, Burke County, and Western North Carolina, homeowners start preparing their homes for fall and winter. HVAC systems get switched from cooling to heating, leaves begin accumulating around foundations, and windows stay closed more often.

But there is one part of the home that is easy to forget: the crawlspace.

After months of summer heat, humidity, condensation, and rainfall, fall can be an excellent time to check your crawlspace for moisture problems and conditions that may contribute to mold growth.

At CleanTech, we have provided professional indoor environmental services since 1994, including mold inspections and mold remediation throughout Morganton and surrounding areas.

Why Crawlspace Problems Can Become Noticeable in the Fall

Western North Carolina's warm, humid summers can create challenging conditions underneath a home.

Moisture may enter a crawlspace through several sources, including:

• High outdoor humidity

• Plumbing leaks

• HVAC condensation

• Poor drainage around the foundation

• Ground moisture

• Missing or damaged vapor barriers

• Water intrusion

• Improper crawlspace ventilation

  
  

A crawlspace does not necessarily have to contain standing water to have a moisture problem. Elevated humidity and damp building materials can also create conditions favorable for mold growth.

By fall, these conditions may have existed for weeks or months without the homeowner realizing there is a problem.

1. Look for Visible Growth on Floor Joists and Wood

One of the first places to inspect is the wood framing underneath the home.

Look carefully at floor joists, subflooring, support beams and other wood surfaces.

Discoloration or unusual growth on these materials may warrant further investigation.

However, appearance alone cannot reliably tell you exactly what a substance is. If you are concerned about possible mold growth, a professional inspection can help evaluate the conditions in the crawlspace and determine appropriate next steps.

2. Pay Attention to Musty Odors

Have you noticed a musty or earthy odor inside your home?

Don't automatically assume the source is somewhere in the living area.

Odors originating in a crawlspace may sometimes become noticeable inside the home, particularly around floors, plumbing penetrations, ductwork or other openings between the crawlspace and living space.

A persistent musty smell can be a reason to investigate for excess moisture or possible mold growth.

3. Check the Vapor Barrier

A crawlspace vapor barrier helps limit moisture coming from exposed soil beneath a home.

Take a look at yours.

Is it torn?

Are large areas of soil exposed?

Has it shifted out of position?

Is water collecting on top of it?

A damaged, incomplete or improperly installed vapor barrier may reduce its effectiveness at controlling ground moisture.

CleanTech provides crawlspace inspections and vapor barrier services for homeowners dealing with moisture-related concerns.

4. Look for Plumbing and HVAC Moisture

Some crawlspace moisture problems come from surprisingly small sources.

A slowly leaking plumbing connection or condensation line can introduce moisture underneath a home for an extended period before anyone notices.

Check around:

• Plumbing pipes

• Drain lines

• HVAC equipment

• Condensation lines

• Ductwork

• Areas directly underneath kitchens and bathrooms

Even a relatively small leak can keep nearby wood or insulation damp.

5. Check for Wet or Sagging Insulation

Crawlspace insulation can also provide clues.

Insulation that is wet, sagging, falling down or visibly stained may indicate that moisture is present or has been present previously.

Simply replacing damaged insulation without determining where the moisture came from may leave the underlying problem unresolved.

Finding the source of the moisture is an important part of addressing crawlspace conditions.

6. Look Around the Foundation After Heavy Rain

Water does not always originate inside the house.

Walk around the exterior of your home and look at how water drains away from the foundation.

Check gutters and downspouts and look for areas where water collects near the house.

Poor exterior drainage can contribute to crawlspace moisture, particularly during periods of repeated rainfall.

The goal should be to direct water away from the foundation, rather than allowing it to collect beside or underneath the home.

Why Check the Crawlspace Before Winter?

Fall provides homeowners with an opportunity to identify moisture concerns that may have developed during the warmer months.

Once colder weather arrives, many homeowners spend less time inspecting the exterior and underneath their homes.

Finding a problem now may give you an opportunity to determine:

Where is the moisture coming from?

Is there visible growth that needs professional evaluation?

Does the vapor barrier need attention?

Is there a plumbing, HVAC or drainage problem contributing to the moisture?

Most importantly, addressing the source of moisture is an essential part of managing a mold or moisture problem.

Cleaning visible growth without addressing the conditions that allowed it to develop may not solve the underlying issue.

Buying a Home This Fall? Don't Forget the Crawlspace

Fall is also a busy time for real estate transactions throughout Morganton and Western North Carolina.

If you're purchasing a home with a crawlspace, consider taking a closer look underneath the property.

A home can appear clean and well maintained upstairs while moisture problems are developing underneath the floor.

Warning signs may include visible growth, standing water, damp wood, damaged insulation, musty odors, plumbing leaks or an inadequate vapor barrier.

When concerns are discovered, a professional mold inspection can provide additional information about conditions in the property.
