Is it bad for your health to have standing water in the basement? - Reader Question

The longer water sits in the basement or crawl space, the more time it has to contribute to the conditions of the home.

Water that sits in an area like the basement, doesn't move, doesn't filter, and is allowed to do so, can breed problems.

Water normally carries bacteria and other microscopic organisms with it. Standing water allows these bacteria to multiply in your home. As water evaporates these bacteria can become air born which will effect your air quality. Standing water also directly effects the amount of moisture in a basement or crawl space which will, again, effect your indoor air quality.

A basement that has an increased level of moisture has an increased chance of harboring mold colonies. Mold requires cool, damp and dark conditions to thrive in addition to a food source. A food source for mold is anything that can be organically decomposed or digested by the mold (wood, cardboard, paper, clothing, pictures, wood stairs, etc.)

Dealing with water quickly is the key to success:
As I mentioned, the longer the water stays untouched in the basement, the more of a chance it will effect, and the longer it will have the ability to effect the indoor air quality of the basement and the home.

Moping up, dry "vac-ing", and drying out the area will help you gain back control of the usable space. Run a dehumidifier and turn the heat on to warm up the basement - this will help the water to be moved off of the floor or the basement.


Don't let the water sit
Move the water, clean it up
Dry out the space - dehumidifier, heat and fans.

The longer the water sits the longer it has to cause problems in the basement - especially in a finished basement.

If your basement or crawl space has even a brief history of this occurring, seriously consider having a GrateDrain system installed in the trouble spots to help keep this from happening again.

Turning the Heat on in winter will show you the actual air quality of your Basement

How would turning the heat on upstairs have anything to do with the air quality of basement? It’s an interesting concept, but it’s one that many air quality experts, including Craig Clark from Ocean State Air in Rhode Island, deals with every winter.

We all know that the condition of the basement affects the air quality in the rest of the home. Lingering water, moisture and water damage, mold or other pollutants in the basement can influence the quality of the air and aggravate sensitivities in the homeowners.

Moisture problems that go unchecked in the summer don’t feel as serious in the winter. The cold air, for the most part, masks the issues in the basement. Humidity and excess moisture build up are as tangible in the winter as they are in the summer months that are naturally humid.

This becomes the combination to cause issues.

Turning on the heat forces warm air through your home, and in many cases your basement as well. This can awaken any unaddressed moisture issues again in the winter. With warm moist air now back again in the basement during winter, people with respiratory issues can be affected again when they least expect it.

“It’s not uncommon for an entire house to get sick because of poor air quality issues in the winter that could have been avoided by addressing them in the summer,” says Craig Clark, president of Ocean State Air in Rhode Island.

“Correcting an air quality issue in the home can avoid complications in months where normally there isn’t a problem.

“If you maintain the Relative Humidity, you can control the dew point and prevent the mold growth on cold surface areas.

“When homeowners turn the heating system on for the first time with mold contamination inside the HVAC system, the dried up mold becomes aerolized and can cause substantial discomfort to persons with mold allergies. A non-viable mold spore or mold fragment can cause as much discomfort as a viable spore or fragment.”

The World Heath Organization back in August finally announced its findings about increased illness in buildings with air quality issues. Occupants of a building with moisture issues are 70% more likely to become ill than occupants of buildings with proper air quality.


Like always, make sure to have your home inspected to make sure that you don’t have moisture or a mold issue. With this new pattern in New England it might be a good idea to have an inspection before cranking the heat this winter.

Basement Mistake pt3 – Thinking that a basement is not part of the house.

Now this might sound down right silly, but many homeowners and even contractors actually treat the basement almost as if it wasn’t really part of the house. You might be saying “well that’s just silly!” and you would be right. The basement is the space created under your home by the walls of your foundation. Since it’s a closed in space, it is very much a part of your home and regularly contributes to the air quality and health of the rest of the home.


Foundation is sick, home is sick.
Movements in the soils around the foundation make the walls move, bricks buckle, or cause cracks in the basement walls. These movements also affect the home directly on top of it by causing ceiling and wall cracks, doors to stick and windows to get shifty. It’s not only connected in a physical way, but is also connected with airflow.

Air from the outside of the home finds its way into the basement through the foundation walls. The air travels up and into the first floor of the home and continues to travel until it reaches a window, roof or some other opening. If the air quality in the basement is poor, than the air quality in the rest of the home is affected and changed. Mold spores, pollutants or other VOCs that have access to your basement have access to the rest of the home.

The recent epidemic of sick-house syndrome is typically caused by problems emanating from the basement. Mold and mildew can quickly turn a home from a safe haven into a place that makes it hard to breathe and can even cause neurological disorders. Leaving the home’s foundation to it’s own devices will only allow further deterioration, cracks, moisture, and problems to occur.


Like any part of your home…
…the foundation needs to be repaired and maintained. Creating a healthy and safe environment will lend itself to creating a healthy and safe home.

Leaving problems like standing water, cracks, or mold to fix themselves will only leave you in solid disappointment.

As you would have a plumber come and tend to your pipes, have a basement health contractor come and inspect the condition of your basement. Providing a Radon Test every 2 years, correcting and foundation stability issues, and attending to moisture and water control needs will have you finally sitting pretty.


Evidence that Contractors think differently about the basement.
I was even surprised to see that many contractors (who aren’t in the basement health industry) see the basement as separate from the rest of the home. Many finishing contractors will build with the same materials as they would on a 1st or 2nd floor project. Organic material such as wood and standard dry walls can turn into hazards when met with moisture issues. This proves that many finishing contractors don’t understand the basement environment and think that the foundation is a separate part of the home.

Providing the same classical finishing methods and materials to a remodeling job in the basement shows that contractors don’t always understand the problems of their materials in the foundation area. Paper-backed dry walls and insulation can feed mold problems. Wood studs can absorb moisture and introduce mold and dry rot odors to the basement. The basement requires different types of materials to be used in the basement and by not understanding this; contractors condemn their remodeling projects to eventual disaster.

The foundation itself, yes, is a separate “piece” of the home, but the conditions within it are very much connected to the rest of the home. This is why thinking this way about the basement is one of the Top 6 Most Common Basement Mistakes.

40% of the Air you breathe, YES, comes from the basement!

Percentages range, but studies all over the world support the fact that yes indeed air moves from your basement up to the rest of the home. 40% or more of the air you breathe on a regular basis comes from the basement.

That link is another one of my articles, recently published, on stack effect, and air quality in the home. Your basement's current state effects the rest of your home more than you know. And if you're looking for a good investment and project to do during these times to not only better the air in your home, but protect your basement, family, and foundation then this is a good article to read.

Indoor Air Quality; Affected by Basmenet

General studies suggest that over 40% of the air that we breathe in the rest of the house comes from the basement. In a cascading effect called Stack Effect. The air joins the rest of the air circulating in the home and eventually finds its way up and out.

However, having an untreated water issue in your basement, or uncontrolled moisture in your basement space can invite more serious matters to affect your Air Quality.

Using quality materials in moisture and water mitigation is so critical now, more than ever. Whatever you do in your basement can have health ramifications upstairs. And if you're subjected to a poor choice by someone who just wanted a check, it can harm you over a long period of time. Open back systems can actually increase the amount of Radon in a home. They can also invite bugs and other small animals to come, eat, live and defecate. Insanitary conditions this day'n'age are totally avoidable and you don't have to live with a bad choice off of someone else's ignorance.

Closed systems don't have any of these effects. There is no open aspect to them. They don't allow moisture or water through, and having a full concrete floor over the drain, small animals and insects can't find their way through. Now that you have full control over your basement moisture and water, a dehumidifier will run more effectively and efficiently. This will save you time, effort, and money, not only down stairs, but upstairs as well. Having less moisture cascading up into your living space will enable your air conditioners to work better.


Your air conditioner actually has to heat the air it takes in, which allows moisture to be removed, and then it cools the air and pumps it back into the house. The less moisture it has to remove from the air, the better it can drop the degree in the room. All of the energy can go into actually cooling the space rather than having to deal with removing moisture first. That's what makes a solid dehumidifier so important to a moisture control system in your basement. You're not only taking care of the space in the basement but minimizing the ramifications of that moisture on the money you're spending on heating and cooling the house upstairs.

A SantaFe Dehumidification Unit is a key element in any basement waterproofing or basement finishing project that you want to have done.
