Charlotte – Triad Homeowners are Being Overcharged for Crawl Space Problems

Charlotte and Triad Homeowners are being overcharged for improperly diagnosed crawl space challenges that create more problems than they solve. A corresponding testimonial is included sharing the story.

 

I recently visited a customer in the Triad market that had some unique challenges to overcome with her crawl space. This customer had spent a fortune with a contractor waterproofing her basement and encapsulating her crawl space. A drain system was installed in the basement section connected to a sump pump. Inside the crawl space, all of the sub-floor insulation had been removed, a 20-mil liner installed over the crawl space soils, crawl space vents sealed, and a spray foam application installed along the curtain wall. See supporting photos.

Since the contractor installed the system, this customer has been experiencing odors and smells that are percolating up from the crawlspace section of the house into the living areas of the home. This 3000 ft.² crawl space basically surrounds the small basement section in a U-shaped layout. The odors were becoming so intense that the customer was reporting respiratory irritations and other health related symptoms from the off gassing of construction materials located inside the crawlspace. A basic inspection of the crawlspace section of the house confirmed the poor air quality and intense smell that was reported by the customer.

When homeowners invest in these types of systems they don't realize that the application of heavy pool liners, spray foam resins, soil gas release, and the effect of other installed construction materials present inside the crawlspace can off gas unpleasant odors inside the space and potentially percolate upwards into the living areas of the home. Because the crawlspace vents are sealed, no outside air exchange is possible to allow fresh air to integrate into the crawlspace environment and/or allow polluted air to escape outside. The heavier concentrations of construction materials installed in a crawl space only heighten the chances of polluting the crawl space environment and adjacent living areas with the contaminated air.

This customer was at wits end with this problem. She was even considering moving out of the house as a last resort. Her concern was obvious, as she could not live happily in her own home, and she could not sell the home until this problem was resolved. The customer reached out to a variety of companies to assist in diagnosing and resolving this issue with no success. Several local companies in particular attempted to sell thousands of dollars of additional products and equipment that will do absolutely nothing for the odors and smells problem that was reported. Both companies wanted to sell the client a $2500 150-pint commercial dehumidifier for the crawlspace. This advice was not only problematic, but completely ignorant of the situation at hand. The wood moisture reading at the time of the inspection was only 7% which is actually too dry.

The customer actually already has a forced air HVAC conversion that services the crawl space environment and appears to be keeping the crawl space adequately dry. This was missed by both companies.

As a matter of fact, according to the customer, wood moisture readings were never taken by the sales people from any of the visiting companies. If this was a true fact, how could a proper diagnosis of the symptoms be made? Simple. They can’t, and they didn’t. Incidentally, adding a dehumidifier into the crawl space environment on this house would only waste energy and actually over dry the floor system and potentially cause the expensive hardwoods upstairs to crack. One of the companies also proposed installing a negative air fan under the crawl space liner as a possible remedy to exhaust the smells. This recommendation is also problematic. Basically, the company recommended installing a Radon mitigation fan under the liner with the duo task of removing odors. First of all, there are no radon problems on this house. Second, a network of drain tiles installed under the liner to an exhaust fan would not carry enough CFM air flow to turn over the crawl space air environment at the necessary pace to remove the odors and smells. Especially above the sealed liner where there would be little to no effect. Not to mention there is no way to turn the fan off. Radon fans are installed to run constantly so unwanted air could be invited into the space to replace the air that is being exhausted causing potential moisture spikes during the summer months. Since this crawl space is already encapsulated, the contractor would have been forced to cut up and remove the current installed liner to install the drain tiles, and then charge for restoring the 20 mil liner to its’ original state. All in all, thousands of dollars in unnecessary work that would not have solved the problem.

 

So why was this mistake made by the crawl space science companies? Simple. Franchisees hire commissioned based sales teams. There is very little emphasis on developing advanced problem solving skills. Manufacturers and sales managers teach a canned approach or a one size fits all mentality for every situation. Sales people that are paid 100% commission have too much temptation to make a sale by embellishing symptoms, misdiagnosing symptoms and/or flat out inventing problems that are not there so they can over sell the job and make a higher commission. This kind of sales environment is not good for the consumer and actually encourages bad behavior by the franchisee.

 

The recommendation of adding a dehumidifier and/or installing negative air fans in this situation shows poor training, poor judgement, lack of education, and/or just a blatant attempt to earn a commission at the clients’ expense. Not to actually solve a complex problem with any certainty. Dehumidifiers reduce moisture. They don’t purify air, and they bleed energy. Negative air fans don’t reduce odors and smells, they create negative pressure, and bleed energy. One company even attempted to sell the customer additional waterproofing programs in the basement and crawl space environments. This diagnosis was ridiculous as the crawlspace and basement sections were completely dry at the time of the inspection. The only item discovered that needed to be addressed was a broken sump pump in the basement sump area. This is a $185 problem, and it was handled during our mobilization. The good news is there is a happy ending to the story! We were able to install a dew point Controlled Ventilation Fan System on this home to mitigate the odors and smells issue reported by the customer for a fraction of the cost proposed by others. This advanced system developed by engineers is the only product of it’s kind in the United States. This system deploys a network of low voltage fans controlled by a factor of dew point. We were able to open up a select few crawlspace vents to bring in outside air, and exhaust the smelly, stale air out in a controlled way that regulates moisture thru a network of sensors, as well as maintaining crawlspace air quality without the use of an expensive dehumidifier in most cases. No additional waterproofing products were needed on this house. Within 24 hours all odors and smells were completely eliminated to the immense joy of the homeowner. The customer now enjoys a comprehensive warranty transferable if she chooses to sell the home. The customer was completely satisfied with the results and very grateful for an accurate diagnosis. For more information on controlled ventilation systems please feel free to reach out to us for a free consultation. We are an independent network of contractors, hygienists, engineers and installers not affiliated with franchisees. We do not use commissioned based sales people for our site consultations. So remember, conduct thorough research before making decisions on crawl space science and remember, Don’t Encapsulate! Ventilate!

TESTIMONIAL

 

Hey Mike,

I have been very happy and feel like I have the freshest air in town in my home. My health is amazing and I have not had any problems with my sinuses, which is a whole new life for me.

This system makes so much more sense than anything else I researched…I love that I am getting fresh air every day especially since 60 to 70% of the air that we breath comes from under the house. I also gave your name to both of my doctors treating me throughout the last 15 years.…They said they feel like they are seeing more patients with “sick house syndrome” and like the
idea of new fresh air constantly coming into your home.

To start from the beginning.

I have had really bad chronic allergy problems since I have lived in Burlington, which was since 2002. I moved into a brick ranch style home that was built in the early 1950s. Last year in 2017, I got so sick with sinus problems, odd chronic headaches and chronic fatigue, that I did not know that I would make it. The doctors had no clue what was wrong and I had been on constant antibiotics and prednisone and nasal spray most of the year and was feeling hopeless because it was constant. I could not get any relief at all.

I found over several months and many people coming to analyze the situation that I had two problems…. fiberglass insulation was coming down abundantly from the attic into my house. Fiberglass particles were in my sinuses, my lungs and my eyes. A couple of other things added to these bizarre events. There were millions of glass particles all over the house which could only be seen when the sun hit the particles or flashlight shined on them. Since there was fiberglass in the hard casing of the air ducts for the heating and cooling system, I had all those removed, which we then found out were full of white mold. The second big problem. It is still a common practice to put fiberglass in the hard casing. Perfect for growing mold. After all the fiberglass was removed from the attic and the basement, the company I used came in and spray foamed everything. Actually, air tight. They also put a thick white plastic all through the crawl space, which looked great and felt clean. After I moved back in the house there was an odd chemical smell that infiltrated my home. I could not believe this was happening. I was considering moving out again with my 6 rescue dogs… which was a major ordeal the first time. I actually closed my business for several weeks to live in my shop. SO NOW, I had 8 to 10 different company’s or people in to my home to see what the chemical odor was…soil gas was the best guess… I later found out by taking a piece of the plastic liner from the crawl space and putting it in a jar with a lid for 5 days. I read this somewhere on the internet and am so grateful someone suggested that. After 5 days I opened the jar and that was the chemical smell that was smelling infiltrating the house. Spraying the foam in the attic and in the basement made my house so air tight I could not breathe….

I desperately searched for help and I came across a video with Michael Masserang and felt like this was a natural and clean solution that was less invasive, simple and smart. I actually begged him to come to Burlington, since they did not come this far out…to evaluate my situation and he did. We got the system installed the next week and the clean air results were immediate because it immediately brings in fresh air and circulates fresh air around the crawl space and expels it on the other side of the house…constant fresh air in….and unfresh air out…It has been the best thing
to bring in fresh air around the clock…especially with the majority of air that we breath comes from under the home. And Michael also put in a small dehumidifier back up program as well to take care of the humidity when needed.

The fresh air in my home makes up a big part of a good, healthy life…with all the obstacles and challenges with these crazy events I am in a great place with my health and the air quality of my home. I highly recommend Michael Masserang and the staff! Their solution is so natural, much less invasive, clean and smart.

Thank you,

Mary Anne Butler,
Burlington, NC
