“Tom was great to work with; I called him specifically about a moisture inspection. He took the time to talk to me throughout the process to let me know exactly what he was doing. I’ve never had that type of experience with an inspector & appreciated the time so much. I feel like that is super unique in his business. Would highly recommend using him for your next home inspection!”

Standard Moisture Intrusion Investigation

$250

This service includes a limited investigation of a specific part of a property. It includes identifying the source of a moisture problem (if possible) using special moisture-detecting equipment such as thermal imaging cameras, moisture meters, and hygrometers. You will receive an email summary of our findings, photos depicting areas of concern, with clear, easy-to-read recommendations within 24 hours. This investigation typically takes about an hour on-site. (If this investigation is added to a home inspection service, the fee is reduced to $150.)

Comprehensive Moisture Intrusion Investigation

$450

This service goes above and beyond our standard moisture intrusion investigation by digging deeper into multiple areas of the property. This may include investigating the attic, exterior, crawl space, basement, bathrooms, and the roof if necessary. We have industry-leading equipment such as thermal imaging cameras, moisture meters, and professional hygrometers, with the ability to access many hard-to-reach points in your property where moisture may be entering. Your report will include a detailed summary of our findings, photos depicting areas of concern, and clear, easy-to-read recommendations. This investigation usually lasts 2-3 hours on-site; you can expect to receive your report within 48 hours.

FREQUENTLY ASKED QUESTIONS

What is moisture intrusion?2020-02-16T11:57:58-06:00

The term refers to unintended moisture that enters through the “Building Envelope”.  The building envelope consists of the exterior shell of your home that’s designed to repel the elements. Examples include: the roof, basement, windows & doors, exterior walls and the drainage plane, foundation waterproofing, exterior house wrap, ice and water shield, and roofing felt, that is behind the exterior finishes. Moisture intrusion can be obvious and easily found or very subtle and require instruments and testing to locate the source.

How is moisture entering my home?2020-02-16T12:03:53-06:00

There are three main “moisture transport vehicles” that create avenues and allow water into your home.

1. Bulk Water Movement

The most common moisture intrusion issues I see in Twin Cities’ homes are a result of “bulk moisture movement”, also known as liquid flow (rain, snow, ground water). This type of intrusion is typically immediate, easily discovered and also the most damaging. Three conditions are required to allow bulk moisture flow into a building: 1) a source of water 2) an opening or failure in the drainage plane of the building and 3) a driving force such as gravity or pressure.

2. Capillary Action

Capillary action refers to the ability of water to travel up against the pull of gravity through a porous material. It works because the friction of the moisture against the wall surface (adhesion to the wall) actually exceeds the cohesive forces between the water molecules. Although not as serious as bulk water movement, capillary forces are both destructive and secretive, since they often work and accumulate in commonly unobserved areas. They can potentially cause significant damage over a period of time without a homeowner’s knowledge.

3. Air Transported Moisture and Diffused Air Flow

Air-transported moisture (water vapor hitchhiking on air) can leak into, or out of buildings. Both uncontrolled pressure sources (wind) and controlled sources (fans and air handlers) can move significant amounts of moist air past a home’s exterior through openings and improperly flashed transitions. A similar process known as “diffused air flow” forces small amounts of moisture in the form of water vapor to pass directly through a building’s envelope. The amount of diffused air flow (vapor) that occurs in a home is determined by two things: the driving force that pushes it and the permeability of the building material the vapor is passing through.

I think my home has a moisture issue, what’s next?2020-02-16T12:10:07-06:00

Eliminating moisture intrusion sources as early as possible is critically important in caring for your property. Examine your house regularly to look for any new staining or moisture. Sometimes, your nose can be a good guide. If you smell a musty odor, follow your nose and see if you can find a probable cause.

If you know moisture is coming in, but can’t find it, it’s time to bring in the professionals.  The longer you wait to solve a moisture intrusion source, the more expensive the fix becomes.

I’m worried that moisture is leading to mold growth, what should I do?2020-02-16T12:18:06-06:00

Branch Property Investigations performs mold testing in residential homes and commercial buildings. So what makes our company unique? We apply 20+ years experience as a mold remediator and water loss specialist to identify likely locations for mold growth. If desired, we can perform a detailed moisture investigation of the entire home as an added service to mold testing. It is important to not only find the mold problem but also understand why it is growing and to eliminate the moisture source so it won’t reoccur. We don’t perform remediation work so we don’t have any conflicts of interest.
