Crawlspaces: To Vent or Not to Vent, that is the question

We have discussed mold activity at length regarding water intrusion and mold growth in basements. As we know, crawlspaces are also under the house, but are a different beast altogether. The lower building areas, such as basements and crawlspaces, most frequently develop mold amplification. We know that moisture is the limiting factor in mold growth.

So the question is: Should I vent my crawlspace or seal it up?

Historically, crawlspaces were vented by definition. Our most frequent finding has been that the ventilation is inadequate or somehow impaired. We wanted ample cross ventilation to capture and remove moisture that originated at floor level. We also recognized that because that meant bringing in outside air, there was the potential for moisture, either liquid or very high humidity, to be drawn into the space and increase the moisture load in the space.

Mold Activity in Basements: Where Does the Water Come From?

We have discussed mold activity at length in previous posts and videos. Mold contamination has become the most common indoor air quality issue we encounter, both in commercial and residential buildings. And the lower building areas, such as basements, crawlspaces and slab on grade areas, most frequently develop mold amplification. Since we know that moisture is the limiting factor in mold growth, we arrive at the following question:

Why does mold like the lower building areas and where does the moisture come from? [Read more…]

Testimonial: My wet basement is dry now!

Dear Dave,

I am writing to compliment Peter Boris and his team of “Basement Waterproofers.”

He did everything that he promised to do from A to Z in an efficient and thorough manner.

Our basement was filled with several inches of water from a recent deluge of wind and rain. The basement and its contents were almost all destroyed.

His team of professionals worked long hours and stayed till their job was completed.

He left us with virtually a new basement that was dry and clean.

I can’t. say enough about what accomplished in a relatively short period of time. I will recommend him and his team to my friends and family.

Thanks, Peter

Testimonial for Basement Technologies

Dear Mr. Kichula,

I am very pleased with the basement water control system that was recently installed for me.

I had cheaper quotes for a French drain but I was impressed with this system. Also, it looks so neat and the pump is so quiet as opposed to the noise of the old system.

Mr. Boris worked very hard and was very professional – he explained each step as he was going to do it.

I would recommend Basement Technologies anytime.

Customer Testimonial Basement Waterproofing NJ

Dear Dave:

Well it’s been a little over a year since you installed our basement waterproofing system. And after the test of time, I can state with absolute certainty that the system works flawlessly. As you know, prior to having your system our basement got wet after nearly every substantial rainfall. It was a nightmare. Everything was on stilts and we would prepare for massive cleanup jobs every few months.

Now for the first time since we purchased the house some 15 years ago, the rains can come and go and I never think about whether our basement will get wet. It is truly remarkable. I cannot recommend your system more highly. It was the best investment we’ve made in our house.

The Basement Technologies crew is on par with your technology. They were caring, courteous and conscientious. They made sure they left the basement just as they found it, aside from a little dust. They expressed genuine concern when they came across any issues and exhibited ingenuity to solve the problems with creative and now time-tested solutions.

I’ve recommended Basement Technologies to friends and will continue to do so to anyone who asks.
