Basement Moisture Sealing: Top Four Steps to Sealing Basements

Basements can let in water, especially during heavy rains. Sealing basements from excess moisture is a great way to add an extra layer of protection against the elements. Problems resulting from water leaks and moisture damage can result in thousands of dollars worth of damage. Here are some tips that will help you seal your basement properly.

1- Moisture can enter your basement in a variety of different ways. When you are sealing your basement you need to keep this in mind. Water can enter your basement through cracks in the concrete, especially during heavy rains. Also, since concrete is porous, it allows a certain amount of water vapor into your basement. To combat the water vapor, people often use a humidifier. However, this method only masks the problem. Sealing the basement offers a much more lasting solution.
2- To seal the basement properly you need to first make sure that all sources of moisture inside the basement are eradicated. One common way moisture forms in the basement is through the dryer vent. Make sure the vent releases the moisture outside. The second way is through the air conditioning ducts. Make sure you insulate them properly to prevent any condensation from forming.
3- The next step to sealing basements is to make sure any rainwater that falls doesn’t go near the foundation. You may need to install a series of gutters and drains to accomplish this, depending on your situation.
4- After you divert the rainwater away from the foundation, the next step to sealing foundations is to make sure openings for any pipes, ducts, etc are properly sealed. Do a thorough inspection of all pipes and ducts to make sure nothing is leaking. Although you may not see any leaks, keep in mind that even the smallest bit of moisture can be damaging, so seal everything with the proper caulking material. Also make sure you caulk and seal any holes in the corners and in the ceiling.
It may take a while to find every area that needs to be sealed, but the more meticulous you are the better your chances of finding everything. After you seal everything, it is a good idea to install a humidifier for extra insurance. If you have a recurrent problem with flooding, it is also a good idea to purchase and install a sump pump.
