Why should I be concerned about my crawl space? – Mimi from Tarzana

Crawl spaces should be inspected frequently. We’ve seen some severe damages to properties related to leaky crawl spaces, whether it’s from drain lines, water pipe leaks, or rain/sprinkler water intrusion.

This being neglected, we have seen severe mold & fungus that cause destruction to wood framing and impact indoor breathing space.

How do you inspect a crawl space? – Manuel from Northridge

The type of inspection depends on the nature of the concern or issue.

Most frequent concerns

Sewer odor: With sewer odors or rotten egg smells, we perform a full crawl inspection under all bathrooms, kitchen, and plumbing. We run water to every fixture to see if there are any leaks.

We also inspect the soil to see if there is standing water.

Mold: We inspect all wood framing and perform moisture readings to suspect areas.

It’s important to also remove any insulation that mold & moisture can be hiding behind.

Part of the Los Angeles crawl space inspection should include a mold air test inside to determine if cross-contamination has occurred.

It’s imperative to determine if there is moisture anywhere, as mold cannot breed without it.

A swab analysis is also a great way to determine if there is mold present and how active it is.

Real estate sale: If your buying or selling a property, and the Home Inspector found issues in the crawl space, then more than likely you’ll need a crawl space pro to figure out what the issue is.

Crawl space cleaning: We get a lot of professionals that work under crawl spaces who bring to the property owners’ attention about their crawl spaces.

Pest control, heating & air companies, plumbers, etc. – all require at times a clean crawl space in order to perform their install or repairs.

Plumbers, for example, will not go under a crawl space with standing sewer water and do repairs, until the drain water is completely extracted.

Where it’s not free, is when there is diagnostic work or inspecting to determine what the conditions are using tools and reporting those findings.

Crawl space leak detection

When finding any leaks in Crawl space, it takes the right tools and proper techniques.

The first steps are testing all the plumbing, flushing all the toilets, and running showers, tubs and sinks.

Then you run a camera through drain lines that dive into the soil and check the air conditioning system, drain pan & drain line. Check for signs of foundation leaks and gas line leaks – check for rusty gas pipes. You also want to check dryer vent lines leaking into crawl space with massive amounts of lint.
