Side Note: Crawl Space

Wood + Water = BAD NEWS

Exposed earth contributes a lot of water vapor into the crawl space air.  The earth is damp and as that damp soil dries into the house.  In climates where there are dirt crawl spaces, you can never dry the earth, and this invisible stream of water vapor from the exposed earth in a crawl spaces continues forever.

There are several ways water gets into a house.  Groundwater seeps, leaks or could even rush into many crawl spaces.  It can enter under the footing, between the footing and the walls, right through block walls, and through cracks in poured walls.  After it seeps in, it just lays there in puddles, slowly evaporating upward into the house.

Some of the common symptoms of a crawl space moisture problem are:

  • Mold or moisture damage in the crawl space or living area
  • Musty odors in the living area
  • Condensation (“sweating”) on air conditioning duct work or equipment
  • Condensation on insulation, water pipes or truss plates in the crawl space
  • Buckled hardwood floors
  • High humidity in the living area
  • Insect infestations
  • Rot in wooden framing members

These symptoms are most often noticed in the humid spring and summer seasons but can occur at any time of the year. Often, the heating and air conditioning contractor is the first person the residents call to deal with the problem. Typically though, the problem is not due to a failure of the air conditioning system; it results from poor moisture control in the crawl space.

Side Note: Just Add Water

In this week’s Side Note, we switch gears from basements to crawl spaces. Since air flows upward into the upper levels of your home from the crawl space, it brings the humidity from the crawl space with it. The effects on your home include:

  • Dust Mites
  • Sticking (swollen) doors and windows
  • Smelly, Damp Carpets
  • Buckling hardwood floors
  • Frost or Condensation and mold on the inside of windows in cool weather
  • Increased energy bills

While damage in the crawl space itself can be obvious, the list above represents many of the effects that can happen UPSTAIRS that you may not associate with your wet or damp crawl space.

Fixing your crawl space is one home repair expense that you can’t afford not to make.

Side Note: Basement Waterproofing – Inside Strategies

In previous posts we’ve covered a few exterior options to protect your basement.  Now let’s review what options you have inside!  By installing a drainage system around the inside of the basement along the wall, you can capture water at the most common point of entry – the floor/wall joint.  Capturing water from the walls can prevent the center of the floor from leaking by intercepting the water at the perimeter.

There are advantages to an interior drainage system.

  1. Accessibility
  2. Affordability
  3. Quick Installation
  4. Serviceable
  5. IT WORKS!

Even in basements that are already finished, it is still much easier to waterproof from the inside than the outside.  Most Full-Time basement waterproofing companies offer interior drainage systems – – – each with their differences. Watch for our next Side Note where we cover the different interior waterproofing options.

Side Note: Outer Limits

By now we’ve learned that there are two types of basements – the ones that already leak and the ones that will eventually leak.  If the soil around the foundation of your home is pitched toward the foundation, it is a good idea to change the grade by adding dirt so that the soil slopes away.  Do not use sand or mulch which may absorb and hold water rather than water flowing away.  Don’t rely on grading alone to protect your foundation and keep your basement dry.

Try to keep any added dirt or additional landscaping 4″ below any siding.  If the siding is close or touching the soils it may rot, creating a new set of issues.  Proper grading as well as the proper use of gutters and downspouts will be a great help to your overall dry basement project.  Don’t rely on clean gutters alone to keep your basement dry.

Side Note: Dry Basement

Buyers expect a dry basement.  No one wants to buy a home with a wet basement.  These days most states have disclosure forms that would require the seller to details a series of questions about the property…one of which is water in the basement.  Home inspectors are trained to find this sort of defect during a standard inspection.  A keen eyewall-floor-joint-basement-water1 for moisture problems can save you time and money.

There’s simply no way to hide a wet basement.  Buyers will often view a wet basement as a “Fixer-Upper” and lower their offer…sometimes up to 10%.  On a $150,000 house, that’s $15,000!  The moral of the story – – Fixing your wet basement is a lot cheaper than not fixing it.

Stay tuned for more information on basement waterproofing!

Side Note: Basement Space

Build-a-Basement-DesignEven though it may not be counted in the actual square footage of your home, your basement is VALUABLE space!  What can you do with your basement?  How about a Playroom for the kids, a Party Room or Family Room?  A home gym to keep you fit and healthy, or maybe a craft room for your creative side?  All of this and more could be possible.

You’re not going to finish your basement you say?  Even an unfinished basement is valuable space.  All the “stuff” that you would normally put into a dry, unfinished basement is now taking up finished space.  It’s crammed into the closets, the spare room, and the garage.  Taking some simple steps to drying and waterproofing your basement, you can move all that “stuff” downstairs and reclaim your finished space.

Keep up with our new series Side Note for more great basement information.

Side Note: Radon Gas & Waterproofing

Radon Gas is a naturally occurring radioactive gas that comes from radium deposits in the earth’s crust.  If present in the soil under your home, it can get sucked into your house via the basement or crawl space.

DON’T PANIC!  It’s fairly common and easy to get rid of.

Some people that know “a little”, think that basement waterproofing systems and radon mitigation systems are incompatible.  While it is true that gaps, cracks and hols in the basement floor and walls need to be sealed as part of the strategy to get rid of Radon, this can be done without compromising the waterproofing system.
