Lebanon, VA ( 5 Layered Walls)

This Crawlspace was different. The front wall of the crawlspace was thin and totally above ground with many intrusions. We literally started seeing snakes BEFORE we got into the crawlspace. Homeowner complained of high heating & cooling cost and thought it might be due to the Vent Fan that had been installed nearly a decade ago. It wasn't the fan. It was a Tjernlund V2D fan and they only use 0.06 amps. The heating and cooling loss was due to the stack effect and a totally exposed front wall. We opted to use 3 layers of Reflectix with 2 layers of 12 mil poly between each layer. His heating bill went down 25% and that was after we removed 800 pounds of floor insulation that was totally ruined.

The client is a regular. They purchase homes, repair them, and sell them. we This job was a 20 mil Poly with a dehumidifier. It required lots of extras that most firms won't do. We replaced the rusted dryer vent, we repaired and replaced the wired netting holding up the insulation. We  blanketed the water heater. We replaced a downspout and routed the rainwater away from the house. We put a handle to hold onto as you  enter the hilly crawlspace. We installed the condensate pump in such a fashion that their air handler could share it. We met Best Buy at the site to install the dryer.  We handle EVERYTHING that involves the crawlspace for this real-estate investor.

Foam Board Adhesive

They never should have insulated the floors inside of crawlspaces. The battle is between the walls of the crawlspace and the weather outside. This Brief video shows ho well we adhere the foam board to the walls in a crawlspace.

Did you know that we can put 2 inch foam board on all the outside walls, install a full system and still cost less than the bigger firms can just put poly on the walls and floor? 

This is name-brand insulation too. Owens-Corning.

Completed Encapsulation 

Not shown in this video was the 20 hours spent on clean out and prep work done before the first piece of poly was put down. There were large solid clay humps near every pier. There was a strong mildew odor and there was almost a truckload of trash and organic material. This video shows a basic repair kit, with a roll of material, scissors, 4 inch waterproof tape and everything needed for a patch. Right beside the crawl door was our 20 year warranty that covers everything wall to wall. The warranty stays with the home.

A Simple Ground Cover/ Fan (Knoxville,TN)

Homeowner chose not to cover the walls as they had almost no moisture in them and he had a fear of having a foundation problem (cracks in the block) and not being able to see it if the poly covered the walls. The ground is the number one offender in his case, so we did a ground cover with a small lip on the walls and piers

Using a Household Dehumidifier in an Encapsulation

The Video Explains the Conditions in Which a Household Dehumidifier CAN be used in Conjunction with an Encapsulation. This Job Came via Another Client Referra​l

Before Video (Meadow Lane)

We got a call from this client after he called an A/C firm for something happening in the crawl space. The A/C technician had used our service only a month earlier. We get 90% of contacts by one client rferring another one. This hame was in good condition except for excessive moisture . Steps had been taken by the homeowner to rid the problem. The rainwater across the rear wall had been routed away from the home and a second layer of contractors plastic had been put down. On the first day of insulation, we were soaking wet from vapor and droplets on the vents and the plastic. This is the condition of the crawlspace before anything had been done by our firm.

After Video (Meadow Lane)

Compare this to the "Before" video listed above. No more warm, moist air coming in through the vents, causing the A/C ducts to sweat. On average, for every 1000 square feet of ground in a crawlspace, as much as 14 gallons of moisture is rising up every day. With 20 mil Silverback poly on the floor, this homeowner wont have either of those moisture issues again. EVER !! You know what? The homeowner didn't pay anything for this encapsulation. The value of this home rose immediately by more than the amount he wrote a check for. And over the course of the next 4 years, the energy savings from this system will even cover the check. 


Asheville, North Carolina 12 Mil Poly

This job was quite a challenge. Thankfully, the homeowner was a builder and quite saavy and even taught us a thing or two.  Our clients really are "The Educated Buyer" that tend to look things up online and then compare what we sell to what they have learned. As a builder, he had access to an electrician. He got his own vent fans and removed block to install the fans.

UtilliTech Condensate Pump

I can't tell you how many $15,000 DryZone systems I have seen with a 20' X 20" puddle of 2" deep water in the crawlspace because they used some $25 condensate pump. Even made a few videos. The High Quality UtilliTech l Pump will last the life of the 20 year warranty and then some. It goes for $77+tax but at least it wont fail.
