Two Vapor Barriers and Standing Water in Crawl Space

Tim Hance of All Islands Home Inspections discovered two (2) or more vapor barriers in a crawl space filled with water at a recent Anacortes, WA home inspection. The reason that two (2) or more vapor barriers is frowned upon is because water, if it enters the crawl space, can become entrapped between vapor barriers, prolonging evaporation time and leading to stagnant water conditions. Here in the Pacific NW, water intrusion into a crawl space or basement should be dealt with promptly as it can lead to structural damage/settling and insect activity (e.g., carpenter ants, anobiid beetles and Pacific Dampwood termites are attracted to moist areas). In this particular case, the installation of a perimeter curtain drain was recommended to the clients by a licensed contractor.

VIDEO: Standing Water in Crawl Space

Standing water was discovered at a recent home inspection on Orcas Island in the San Juan Islands. If you see standing water or water intrusion in your crawl space, it’s important to deal with it sooner than later as standing water can lead to structural settling and WDO (wood destroying insect) activity/damage in the home, together with moisture related issues within. The longer water intrusion persists, the more expensive the fix typically becomes.

Water Intrusion in Crawl Spaces

Water intrusion under homes is an issue that is somewhat common in the Pacific Northwest, but very important to repair.  Water intrusion and standing water conditions in crawl spaces are most often the result of (1) water intrusion from the exterior (e.g., failed/insufficient perimeter footing drains, gutter downspouts discharging directly adjacent the home, lack of gutters at eaves, improper grading not sloped away from the home, water intrusion directly through the foundation wall itself) or (2) a plumbing leak in the crawl space.  Less likely- and really quite rare- is a local spring underneath the home itself which, if you have one, it just needs to be directed out of the crawl space through ditching, drain rock and perforated piping.

Video: Handyman Support Posts in Crawl Space

Handyman support columns and bases were discovered under a masonry fireplace in the crawl space at a recent home inspection in Oak Harbor on Whidbey Island. Upside down CMU masonry blocks (holes should face upwards!) and aggressive shimming, together with the lack of a positive connection between the post base and above floor structure, warranted further evaluation and repair by a qualified contractor.

Video: Completely Disconnected Ducting in Crawl Space

I discovered completely disconnected ducting in the crawl space at a recent home inspection in Oak Harbor on Whidbey Island. In this particular instance, this ducting was for mechanically ventilating the crawl space area, and had no bearing on the heating system for the home. That said, because it was disconnected, clearly the ventilation system wasn’t functioning as intended or designed and required repair. I frequently discover completely disconnected ducting in crawl space areas for furnaces which significantly compromises the heating efficiency within homes and nicely heats the crawl space areas. Most often, homeowners have no idea because they rarely traverse their crawl space areas.

Video: Water Intrusion and Damaged OSB Sheathing in Crawl Space!

Water intrusion and damage were noted at OSB structural wall sheathing in the crawl space at a recent home inspection on Orcas Island in the San Juan Islands. I like to say “Water is the enemy” to my clients, because much of what I report as a home inspector in the Pacific Northwest has to do with water damage. Water can lead to structural damage, settling, mold, and insect activity/damage (e.g., carpenter ants, anobiid beetles, termites, moisture ants, rot fungus, etc.). So, if you see water intrusion, deal with it sooner than later because repairs become much more expensive with time.

VIDEO: Standing Water and NON-FUNCTIONAL Sump Pump in Crawl Space!

A non-functional sump pump and standing water conditions were discovered in a crawl space at a recent home inspection on Orcas Island in the San Juan Islands. It’s important to monitor crawl space sump pumps to ensure they’re functioning properly as standing water conditions can lead to structural settlement and insect activity/damage. Inquire with contractors about a remote monitoring system to alert you remotely to a non-functional sump pump; this will keep you from having to go into a dirty crawl space!

Video: Waterbed in crawlspace?!

The crawl space looked great, new vapor barrier installed, nice and clean. However, when I got into the deeper recesses of the crawl space, I noted it was like I was walking on a water bed! 3-4 inches of standing water was under the black plastic vapor barrier in many areas. Standing water and water intrusion in crawl spaces puts the building at risk of water, insect and structural damage and is nothing to be dismissive about. In this case, at this Orcas Island home inspection, I recommended further evaluation by a qualified contractor to make necessary repairs and eliminate water intrusion into the crawl space area.
