Crawlspaces and Dehumidifiers

A dry home requires controlling the moisture in your crawlspace.

Service technicians are people we like to trust to do their job competently but they sometimes get in a hurry.  Did they put everything back where it goes?  For instance: All of us have gotten our oil changed, right?  We like to trust them as the “experts” because changing oil is what they do all day.  How many people do we know who have said, “They forgot to put my oil cap back on!”  The same applies to your home.  You need to be able to trust that the work is complete.  Has your vapor become compromised due to someone crawling across it?  Did the cover get re-installed on that junction box?  Did they clean up after themselves or leave debris lying about? Be Informed!

The Checklist

  1. The Crawlspace door: Is it in good shape (hinges, latches, wood, etc.)?  Does it seal properly?  The crawlspace access door is your first line of defense against undesirable animals gaining entry to underneath your home.  Yikes!
  2. Fungal Growth: Any sign of fungal growth can be quickly nipped in the bud before it gets a chance to become an issue.  Fungal growth is a sure sign that your crawlspace has a moisture problem.
  3. Insulation condition: Hanging insulation can mean excess condensation is occurring in your crawlspace.  We also look for signs of rodents nesting in your warm insulation.
  4. Humidity Levels: Humidity control is key to keeping troublesome fungal growth at bay.
  5. Water Staining: Staining on your foundation walls from water/moisture is a sure sign of bigger issues. Block and brick are NOT impervious to water penetration; moisture can make its way into your crawlspace.   Is the water around your home being controlled?  We will let you know.
  6. Obvious Leaks from Systems: Leaks can become a headache if they are not caught.  Not only do leaks create unwanted moisture in a crawlspace, they cost you money…now.  Plumbing lines, water heaters and HVAC units can all create unwanted moisture issues.  Catch them quickly and have them addressed before your wallet starts dripping!
  7. Ductwork: Your ductwork is a major contributor to what you may be experiencing in your home.  A leaky seam/connection can allow “dirty” crawlspace air to be pulled into the duct from the crawlspace as the “clean” air travels through as it heats or cools your home.  Bleh!  We also inspect for compromised duct insulation and age decomposition.
  8. Moisture Levels: Moisture readings will be taken in your wooden floor system.  Elevated levels indicate a problem.
  9. Potential Hazards: Rodents are notorious for wreaking havoc in a home.  They will chew wires, plastic, ductwork…whatever they can sink their teeth into.   They also leave a mess that is potentially hazardous to humans.  Not to mention the fact that they will scare you to death if you come across one!

A clean and dry crawlspace

Since as much as half of the air in your home comes up from your crawl space, it’s important to keep this space underneath your home as dry and clean as possible. Adding a vapor barrier and dehumidifier in your crawl space is the one of the best ways to protect your home from problems caused by crawl space moisture.

Improved Air Quality

Fewer pest problems

Underneath a house, a crawl space is shown with a new vapor barrier installed on the ground. The reflective insulation on the walls and the wooden beams of the house's substructure are visible, indicating measures taken for moisture control and energy efficiency.

Automatically enroll in our Crawl Space Monitoring Program

If we perform work on your crawlspace, we will monitor it for free for as long as you’re at that property and maintain our free yearly inspection.  

Find & Stop the Water

Before modifying your crawl space, it’s important to take care of any water issues, including plumbing leaks, foundation leaks, and drainage problems to prevent water damage and keep your crawl space dry. We can help stop water from coming into your crawl space by installing a drainage system around the perimeter designed specifically for the crawl space.

Waterproof & Prevent Moisture

Often, moisture enters your crawl space through the ground. Adding a vapor barrier in your crawl space helps inhibit mold growth, wood rot, and pest infestations.  We also evaluate any air leaks that may be coming from your foundation, vents, pipes, or electrical wires.  The smallest unsealed area can cause major problems for a crawl space moisture levels!

We cover the crawl space floor and with a heavy-duty,  reinforced polymer liner vapor barrier. When installed as part of a complete sealed crawl space system, this helps provide a dry, healthy crawl space that can be safely used for storage.

  • Foundation vents and foundation penetrations must be sealed with rigid sheet foam and/or expanding fire foam.
  • Crawl space access door must be treated like an exterior door and sealed around the perimeter
  • Access holes to voids underneath porches sealed with rigid sheet foam and expanding foam.
  • A drain should be installed in the vapor barrier at the positive drain.

Dehumidifier Installation

Installing a dehumidifier will help protect your remediation investment by controlling present and future moisture levels in the crawlspace. This will help to inhibit future fungal growth from occurring. Our dehumidifiers are powerful commercial units that are specifically designed for your specific crawlspace size and deliver quiet, energy-efficient service.

  • Dehumidifiers are installed as centrally located as possible within the space
  • GFCI outlet is required
  • Dehumidifiers are not attached to the floor system, reducing any noise/vibration transfer into the living space
  • A separate condensate line and/or sump dump installed based on your space
  • Ducting of the dehumidifier is an option in situations where there is a separate area requiring dehumidified air such as an addition.
