exposed dirt crawl space

View all posts by Michael Church . Kansas. If fixing your crawl space can make the home cleaner, healthier and more energy efficient, why wouldn't everyone fix their crawl spaces right now?

We also have a few small places of surface mold growth.

Also should we remove the plastic too? Getting rid of mold and moisture should not only reduce musty odors but also enhance the indoor air quality in your house.

The Journal of toxicological sciences 39, no.

When given the chance, we all like to help save natural resources and help the planet. Sure Chris,By covering part of a dirt floor with poly sheeting you reduce the moisture uptake into the building and reduce mold and moisture problems.But in my OPINION it would be odd to do just part of the proper job.And yes, as your question implies, we cannot assume that 80% coverage would reduce the problem by 80%.Think of it this way:Suppose you cover 80% of the dirt with poly and then next year find that water is entering the crawl space, perhaps even puddling atop the poly.

If every crawl space in the U.S. and Canada was fixed, these homeowners would save 27 billion dollars in energy costs each year, every year.We all like to invest money wisely, save energy and live comfortably.

Adding gutters plus downspouts that get water 10-12 ft away and to a location where it keeps going would be very important - but if the home is unattended the gutters will clog and spill over at the foundation all over again.

(Mar 18, 2015) Travis Simons said:I didn't know that putting a ground cover would reduce moisture from capillary rise by up to 90 percent. In terms of environmental impact, over the course of 8 years, an encapsulated crawl space can help save 400,000 cubic feet of natural gas (or oil) and prevent 26 tons of carbon dioxide (CO2) from being released into the atmosphere from your home.

Most of the time, the cost of the repair is a big deterrent. What should I do? (Apr 14, 2015) lexi63 said:should a water barrier ( large black plastic ) , be put over saturated ground ?

What are your thoughts?

If mold or mildew grows in your crawlspace, a musty stench will invade your home.

Within the same period, 5,100 tons less carbon dioxide would be released into the atmosphere. We have had our entire crawl space worked on.

Would it be worthwhile to add gutters to make sure that water is taken away from the house?

In 2013 Mlhaupt (2013) pointed out that there was actually rather little research on the respiratory hazards of offgassing from such material. Hi,

That's an approach I've followed successfully in the past.

Michael Church has been involved with indoor air quality since 2005 and feels the unhealthy crawl space is one of the major problems causing poor indoor air quality.

If they were heated by oil, they will save 18,000 gallons each year or 450,000 gallons over 25 years.

Waterproof the inside of the garage and the crawl space with a water management system.

Is this normal?

Tons of franchise opportunities are now available.

Do I have to pull away the fiberglass and attach the plastic sheet to the wall underneath somehow? This brings in cold air from the outside into the house during the winter.

Too often people blame a spring or rising ground water but fail to see roof spillage by the foundation.

Over 75,000 crawl spaces were already fixed using something called the CleanSpace Crawl Space Encapsulation System. Georgia &

If so, pleasecontact usto schedule your assessment. Many homeowners try to keep the cold air out by insulating the floor above the crawl space with fiberglass batts.

This way they can place all the mechanical, plumbing, and other eyesore building materials in the crawl space while saving money in the construction process. (Mar 31, 2013) Patti said:When I moved in the partially covered dirt crawl space was dry with no water issues.

What is the best way to remove construction debris, sawdust, etc.

In this case should we increase ventilation?

Your crawl space can be a haven for pests & other insects if it has holes in the foundation, damaged or missing access vents, or poorly installed doors.

This would cost less than half of the "full encapsulation" procedures.

Any break in the moisture path is helpful in controlling moisture in a building, but it is even more critical to understand that unless soil is covered in a typical (damp or wet) crawl space, the combination of temperature differences, humidity differences, and air movement upwards out of the crawl area, make the crawl space a water pump pushing moisture up into the building. Black plastic was laid up to the block walls. I believe that i have a spring that introduces the water to the crawlspace. Vapor barriers are usually installed in dirt crawl spaces and are essential to help control moisture but are only one piece of the puzzle. I am purchasing a home built in 1980, the current heat pump is junk so I thought I would remove all the old ducting and encapsulate the crawl space before I replace the heat pump. Insects and other pests love dark and damp places, and they move right in.

Fixing your crawl space is a one-time investment that will help you accomplish all of these things -- and after 8 years, it is free! We have no relationship with advertisers, products, or services discussed at this website.

We can not run heat in the crawlspace year round since we only use the house in Summer.

(July 24, 2015) JohnHomeowner said:Can I use my heat pump to supply conditioned air beneath the house? I notice though that it is squishy in some places when I walk on the ground cover. Shouldn't the barrier cover the entire ground under the house.

It costs a lot of money to build basements or level uneven soil so the home builder created the elevated home design on a crawl space.

They were all built according to building codes, yet they are highly dysfunctional.

In 8 years you will not only have all your money back, but you will have enjoyed a more comfortable and healthier home. Don't solely rely on a cheap loose-laid vapor barrier to control humidity in your dirt crawl space.

to sort this out and offer sound advice. ** Warranties vary by product and service. common sense tells me the ground shoild be as dry as possible to do this procedure , not do half the job, install water barrier, then allow flooding to take place then close the crawl space up with saturated ground .

We have no standing water but the block walls do show signs of moisture in spots.

We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. Theyll be able to get water easily through condensation, puddles, and other sources. You will be unnecesssarilyi increasing heating or cooling costs; why not just seal the area, put down a poly vapor barrier, and run a dehumidifer? How to get that out?

Raising the whole structure to provide room below. The hardwood floors are to beautiful to cover. Seal openings in the mobile home floor that could permit moisture or mold passing up into the occupied space; Inspect and complete any missing insulation under the floor.

Crawl space dehumidifiers are often overlooked, but they are our #1 recommended appliance to install in a moist crawl space. But don't forget to check outdoors for other water sources. This brings in cold air from the outside into the house during the winter.Many homeowners try to keep the cold air out by insulating the floor above the crawl space with fiberglass batts.

I have a partial encapsulation and treated mold and fungus in 2017.

The insulation is not in an enclosed cavity where it can do any good.

I got a confirmation from one of the companies that the dehumidifier size was proper for my crawlspace and positioned correctly. I am on a grade with a positive drain that works and have never seen any standing water in the crawl space but my cinder blocks are wet all the way to the rim board in the crawl space.

Moisture makes it sag and gravity pulls it to the ground, creating gaps for air to leak through. We would like to reduce crawl space humidity but the cost of "encapsulation" is very high and we are searching of other less costly reasonable options if they exist.

Or use the SEARCH BOX found below to Ask a Question or Search InspectApedia. Thanks Dan.

I guess my question is: does 80% coverage give a 80% reduction in moisture, or will it be significantly less effective due to the uncovered areas?

On 2019-04-28 by (mod) - off-gassing from poly crawl space barriers may be toxic.

Andy I'm mixed up - is it a crawlspace or a basement?

Is it possible that part of your crawlspace was not accessible?

Serious problems require professional attention. In your question we are literally stuck between a rock and a hard place - rocky ground under the home, only 5" of clearance at the low end - and a wood floor above.

yes I can certainly best practice to cover all of the crawlspace floor and even to run slightly up the walls of the crawlspace.

Don't solely rely on a cheap loose-laid vapor barrier to control humidity in your dirt crawl space.

If you notice white or chalky markings on your foundation walls, its a good sign that theres a lot of standing water in your crawl space.

Hello Pam, it would be a good idea to look at your crawl space and garage from several areas.

I am not in your area of service, I live in Montpelier, VA.

When this humidity is absorbed by wood building materials in the crawl space and the rest of your home, it can be a disaster once mold and wood rot fungus begin destroying the foundation. If on top of the plastic, collect and bag the debris then sweep and vacuum up the sawdust. The problem is that the air in a house flows from the bottom to the top.

Hello Sam, sounds like you have a lot of information to digest and I hope this helps. Also, if your sub-floor insulation is damp or there is mold on the joists, remove it and install foundation wall insulation, preferably termite resistant foam board or insul-barrier (links to our diy store for wall insulation: https://diy.crawlspaceninja.com/wall-insulation/). I need a bit more info. Dehumidifiers in Dirt Crawl Spaces

You are starting at the right place by stoping outside sources of water entry or moisture entry into the crawl area, particularly roof drainage and surface drainage defects. Is there benefit in covering most, but not all, or the crawl space dirt floor with poly sheeting? Good luck! Would this be a reasonable approach? Can I put carpet over vapor barrier in the crawl place?

My plan is to remove all floor insulation, install polystyrene foam boards along the foundation wall and then encapsulate. We live in Canada where it is hot and humid in the summer months and very cold in the winter months. In this video, building scientist Larry Janesky explains how crawl spaces work, why they cause so much energy waste and why fixing a dirt-floored, vented crawl space is one of the "Ideas Worth Sharing."

2. more likely: carefully removing the flooring from above to give working space, preserving the floor boards, installing plastic over the ground, inspecting for insect and rot damage and repairing as needed, then solid foam insulation between the floor joists, then floor replacement. Are we looking at the top of the foundation wall in your photo - bottom of photo is top of concrete block wall? If you don't fix it now, you will be overpaying for heating and cooling every month and in 8 years you would have spent the full amount that the repair would have cost while living in discomfort.

"Encapsulation" without cleaning and without fixing the source of mold growth in a building would be an improper approach. That's why we want the moisture barrier to be complete and not leaky. Put gravel over barrier in winter when building house a lot of water got in. any suggestions? My footer is above grade in other words I cant put it beside the footer. But it's a terrible idea: Why would you want to put carpet into a place that's at risk of collecting dampness, insects, mice, or other pests? Crawl space encapsulation is an efficient method of preventing termites and other pests from entering your home. Do you need help with crawl space encapsulation in Alabama,Georgia, Delaware, North Carolina, Tennessee, Kentucky, or South Carolina? That may mean a combination of a more informed examination of where water is coming from and how to direct it away from the building (start with roof and surface runoff), combined if necessary with far more costly excavation and installation of waterproofing under and around the foundation - converting it into a boat, and capped by great attention to detail to make sure that once your boat has been built, there are no leaks into it from above (roof, plumbing, windows, doors, siding, etc.). What Next? There is some moisture showing on the cinderblock around the crawlspace.

Science of the Total Environment 409, no. The best solution for these problems is Crawl space encapsulation.

Termites are the most common of these insects. Mold and mildew thrive in crawl spaces, causing a slew of additional problems.

Vapor barriers are usually installed in dirt crawl spaces and are essential to help control moisture but are only one piece of the puzzle.

They make homes uncomfortable, unhealthy and cost homeowners a lot of money by significantly increasing their heating and cooling expenses.

These questions and answers about poly or other ground covers in crawl spaces were posted originally at CRAWL SPACE GROUND COVERS - you'll want to read through Steve's advice given there.

My crawlspace walls have pink fiberglass insulation atrached to them. Gutter screens can reduce but not eliminate the frequency of gutter cleanout needed.

And with proper cleaning encapsulation is often not necessary.

An intercept drain on the upslope side of the building can intercept groundwater and direct it away; A swale on the upside of the home can intercept and reroute surface runoff, though in heavy frozen snowfall it may stop working; If water stains are high on the foundation wall I'd start with roof runoff control and a swale. That would put a little heat into the basement or crawl area too. Yet this video shows that fixing your crawl space is not only a good idea, it is an excellent investment that, on average, will pay for itself in about 8 years, in energy savings alone!
