Tackling Mold In Your Crawlspace with Mike Holmes
Have you been down into your crawl space lately? Many homeowners who have them don’t know what to do with them – and if they go down there and smell something musty or find traces of mold they begin to panic. Trust me, I’ve gotten the emails. If your crawl space has mold you’re really dealing with two problems: the mold itself, and the source – which means you probably have a moisture problem.
Let’s tackle these issues one by one.
How To Get Rid of the Mold
If you have a major mold outbreak – I’m talking 10 square feet or more – call in a mold removal specialist. The problem is likely too big for you to handle on your own.
For smaller traces of mold, you can probably handle clean up yourself. Before you even start, make sure you’ve got the proper protective clothing on. When going into an enclosed space, especially, you want to make sure you’re not breathing in mold spores. So always wear your masks, gloves, and protective clothing.
Start with Concrobium Mold Control and apply it to the effected areas. For smaller, enclosed areas like your crawl space, I recommend renting a fogging machine and using the Mold Control to mist the crawl space. It will coat the area, and eliminate mold and that musty smell while leaving behind an antibacterial shield to prevent future mold growth.
Once you’ve taken care of the mold, there still may be some remaining stains in your crawl space. Using Concrobium Mold Stain Eraser will remove that embedded staining on the surface without leaving residue behind.
Areas that are prone to trap humidity, like crawl spaces and attics can be prone to mold. Placing Concrobium Moisture Grabbers XL in these areas will absorb the moisture as it enters the space, preventing mold growth.
Keep The Moisture Out & Mold From Returning
When you only deal with the mold, without fixing the source – well – you’ll get mold again and again. Depending on whether your crawl space is a cold zone or a warm zone.
If your crawl space is a cold zone, that means it shouldn’t be pulling heat from the warm air in your home. If you’re having issues with mold and moisture, you space my not be properly vented. Two vents on either side of your crawl space should be sufficient. You will also need to place insulation under the floors in your home so the hot and cold air don’t meet in the middle and create moisture. While you’re making repairs in the crawl space – double check that any piping in there is properly insulated so they don’t freeze during the winter.
If your crawl space is part of the warm section of your home, that means your space better be properly insulated so you aren’t losing heat to the outside. If it’s not properly insulated, make sure to take care of that first. I like using a closed cell, two pound spray foam because it will keep the heat in, as well as act like a vapor barrier to fight against that moisture. If you’re filling your space with batt insulation instead, make sure you also install a vapor barrier – and it needs to be on the warm side of the house.
You may think that mold and moisture in your crawl space are just a given, but the truth is, it’s not. If you understand how to prevent moisture buildup in the space, you can keep the water out and that will keep the mold at bay.
