Dealing With Water Under Pier And Beam House

The most common causes of water under your pier & beam house include:

  • The exterior water is not being redirected away from your home in the form of a slope, resulting in the water running towards your home and gathering beneath it. 
  • Leaking pipes could be why there has been collecting water beneath your home since it is not a place you commonly check for leaks. 
  • You do not have a drainage system established. Most houses need some sort of drainage system since water is bound to end up underneath your home if there has been heavy rain.

Apart from Repairing any Plumbing leaks & Drying them out with fans ,the main way to ensure there is no damage done by rainwater is to have a proper drainage system.

This will ensure that if there is large rainfall or flood it would not cause any damage to the beams beneath your home. 

Many people opt for a natural drainage system by having a slope from beneath their home to the exterior, naturally draining water.

But there are also systems you can install, like the “French Drainage System,” to ensure there is no buildup of water beneath your home.

Preventing Standing Water under Pier & Beam House:

As they say, “Prevention is better than cure.”

  • Make sure that you have all the possible drainage systems in place to prevent the water from staying beneath your pier and beam home. 
  • Ensure that you have a professional come and inspect the beams of your house after you have experienced a leak or a flood
  • Ensure that you have a sump Pump on hand in case of emergency to pump the water away if it’s not draining itself.
  • Try to get your hands-on a moisture barrier.

It would be a good idea to do additional research on underground drainage systems and what it entails.

Or contact a professional that will be able to inform you which systems should be put in place to ensure the crawlspace under your pier & beam home stays dry.

The most common underground drainage system for pier&beam houses is when water seeps through the soil into underground pipes, distributing the water elsewhere. 

Ensure that these pipes are of good quality and will be adequate for the area you live in.

Ideal Moisture Under Pier & Beam Houses

Too much water is not a good thing, but too little is also not beneficial to the soil beneath your home that holds the beams in place. 

Ideally, the moisture level in your crawl space beneath your pier and beam house should be no higher than 55%.

If, however, the humidity does reach above that level, fans can be a highly effective and quick fix to drop the humidity to a reasonable amount. 

When To Call a Professional:

You have attempted the above methods but have seen 0% improvement. It may be time to call a professional.

On the other hand, you may have tried a few techniques and see that the water has cleared up, but something still seems off, and you are unsure if your beams have been damaged. 

Here is how to know when you should call a professional:

  • You have tried everything, but the water isn’t drying up. 
  • You have realized there is a horrid odor starting to form beneath your home. 
  • If the water damage is due to leaking pipes,
