Keep it Dry - Dehumidify!

"All Building Science Experts Now Say That Vented 

Dirt Crawlspaces Are A Bad idea!"

The Solution:

  1. Installation of permanent commercial Dehumidification System to dry everything out & keep it dry permanently
  2. Sanitize, clean and seal all wood under flooring
  3. Our appropriate size area liner is installed below dehumidifier to protect it and help create vapor drive condition for the whole space

I have been involved in many aspects of the Indoor Air Quality business and Healthy Homes for over 30 years. The Raleigh, NC area and Southeast coastal areas such as Jacksonville, Fl have one big thing in common: significant water table issues. Raleigh has clay soil and many springs so consequently builders, for many years, have preferred houses on crawlspaces. Other coastal areas oftentimes have problems with rising water tables from storms, etc. Either way, these issues make crawlspace houses very vulnerable to moisture damage and resulting microbial increase such as mold in the house. I believe the Turners Underseal System is ideally suited to fixing your crawlspace problems and keeping it dry permanently. It's all about you breathing healthy air. - Chris Turner -

Moist Crawlspaces could be hazardous to your health

ALL dirt crawlspaces are moist because of ground water evaporation and foundation vents.

Dust mites, mold and other toxins are the most common allergens present in high humidity environments.

You MUST keep the relative humidity below 50% to solve these problems! 

Crawlspace moisture is your enemy and we need to stop it

See Failed Encapsulation below from one of our competitors

The entire industry of “crawlspace  encapsulation “ is based on one main point: the entire crawlspace is sealed off from the outside and from the ground with plastic. However, this is completely untrue. Every “encapsulated” Crawlspace I have ever seen has many leaks and that is a huge problem. The installed plastic causes a large buildup of a toxic stew underneath releasing all of the resulting contaminants right into the crawlspace and into the house. How is it possible that this idea ever got popular? “Encapsulation “is one of the biggest gimmicks in the history of residential construction. Chris Turner

Is it a Miracle?.................

Susan just called. She had been previously diagnosed with mold illness including sinus headaches. After having our Crawlspace Dry System installed three months ago, she now says that she has not had a single headache since.  Victory!

We just finished a Dry Crawlspace job at a home off of Falls of Neuse Rd. This crawlspace was extremely damp and dripping off ductwork like crazy. Today is Sunday and I went inside it to take pictures. Oh! it smells much better and it is completely dry. Our installer, Luis is fantastic.

Luis says that he loves our dry crawlspace system so much that he doesn't watch much football anymore. He really enjoys watching his guys fix the crawlspaces and take out bad insulation much more.

Heather at W.W. Builders just informed us that the home we installed The Dry system in Ortega for them has been what seems to be a miracle. The absolutely nasty wood floor cupping has completely settled down to where you can't even tell it had a problem in just 3 weeks!

I just stopped by a residential job site that Karl Hague with the mold remediation company was doing insurance work for a slow bathroom leak that did extensive damage to the floor above the crawlspace. He said the damage was much worse because of the spray foam on the subfloor that kept water and moisture on the wood. He said that if there was no spray foam and it had our Dry System the damage would have been much less.

KC Bell says: "Turners Underseal has been a great company to work with. Professional and prompt from start to finish-Chris answered all my questions and educated me on crawlspace air handling. The air ducts and dry system have made an immediate difference in our homes comfort. The musty smell is gone, and the air is fresh and dry. I give them the highest recommendation."

Great news, we just checked the humidity in David Foerster's crawlspace because the wood flooring guy wants to redo the floor on the 1st floor. We put the dehumidification system in the crawlspace a year ago and everything feels dry and registers very dry. This system works every time.

Indoor Air Quality tip:  Always use semi-gloss paint on the walls of your bathrooms for better air quality.

FYI: Encapsulated crawlspaces have an inherent flaw. Because they are not sealed, (they have tiny holes in the liner, seam tape, around piers and walls) microbial colonies can multiply in areas underneath the liner and then release toxins and odors into the crawlspace and in the house.

We are getting fantastic results from the Installation of our Commercial Crawlspace Dehumidification System. Due to year around humidity from dirt crawlspaces in our area, our dehumidifiers improve air quality for the entire home. Keep it dry from the bottom up.

Did you know that moisture pouring into your home from the dirt crawlspace is a major cause of wood floor cupping? Your air conditioning system also has to work harder because of the moisture.

"One thing that I have noticed directly after we have applied Turners Underseal wood sealer in crawlspaces is how much better everything smells."  Chris Turner

Here is another very good reason never to put spray foam insulation in a crawlspace.  If  termites, especially the aggressive Formosan termites were to infest the subfloor, an inspector would never be able to see the evidence with the wood covered in foam.


It is sometimes necessary to have our ducted dehumidifier to dry out a wet crawlspace before treatment, as in this case.
