Crawl Space Maintenance
When Under Means In
If your home has a crawl space, it's a good idea to have a good look at the space several times a year.
Your crawl space is part of the building envelope and your home environment. You need to have it tested for radon gas, and take note of any flooding issues—either from ground water or plumbing leaks. If you see any water in your crawl space it is prudent to have it evaluated right away.
I recommend that crawl spaces be checked professionally every year along with the homeowner examining the area every six months; however, sump pumps in the crawl space require even more frequent inspections.
If your crawl space has not been inspected in for 5 or 10 years—an immediate inspection is crucial.
What to Look For
The most common problems found in Portland area crawl spaces are due to dampness. The first thing to inspect is the 6 Mil plastic vapor barrier. In order to avoid dampness in your crawl space you need to make sure the vapor barrier covers the dirt completely.
What to look for when checking your crawl space:
- Signs of rodent activity such as droppings or pulled down insulation
- Missing insulation
- Loose joist brackets
- Openings in or broken air ducts
- Signs of dry rot or water damage
- Evidence of insect damage
