Conducting an inspection for moisture intrusion in a home can allow for possible issues to be recognized before they end up being expensive repairs. A thorough assessment of the home’s structure, foundation, and building envelope can help reveal to you areas where water damage is frequently overlooked within a structure. It is important to note that moisture issues affect both site-built and manufactured homes in much the same ways, meaning there are many commonalities in what we will find, and how we should go about remediating the situation.
Whenever a home inspection is ordered for an evaluation of any locations where moisture intrusion is seen to be present, the proper methods and tools should be utilized to understand and determine the needs of, and extent of remedial action required.
If only a small location is impacted, restricted removal may not be possible. The degree of extraction needs should be identified by a certificated individual with experience working on issues such as these.
This issue will generally begin around the outer envelope of the structure. This type of moisture intrusion is typically found in dealing with a building’s walls when some element of the wall’s structural components has actually stopped working. Water will move through the wall over time from the outside to the interior surface area where paint damage will typically result. Water caught behind the paint, wallpaper, or products connected to the wall can cause mold development.
Figure out the kind of pipeline and the area of the break. Make a suitable home inspection demand to the Treatment Plant or the proper department. The level of removal is based upon a variety of aspects consisting of the contents of the pipeline that broke and the length of time that passed from the real pipeline break until its discovery.
Moisture intrusion can be the reason for serious structural problems, in addition to health conditions for the home’s residents. Inspectors must have at least a fundamental understanding of how moisture might enter into a structure, what locations, and where issues frequently take place.
Any permeable product that has actually entered contact with sewage-tainted water is treated as though it were polluted and should be removed and/or disposed of immediately. This consists of carpet, drywall, and ceiling tiles along with other products such as books and paper items.
Water invasion of this type generally leads to water-damaged ceiling tiles. The primary step in dealing with the concern is to figure out the source of the water issue. Remediation efforts demand repair requests be made to the Treatment Plant or the proper department for corrective action as quickly as an item is found.
These issues need to be separately evaluated so that proper corrective action can be taken. Consistently removing the defective or damaged paint and repainting the interior surface areas do not do anything to remedy the issue.
Non-porous products can generally be cleaned up and sterilized.
Water harmed ceiling tiles require to be changed as quickly as possible. Damaged ceiling tiles must not be left in location due to the high likelihood of mold development at the site of the damage. In most cases, mold development will take place on the backside of the tile well before it shows up on the front side.
Locations impacted by a sewage system line back-up requirement to have limited tenancy up until the issue is attended to and the site cleaned up. Demands for a home inspection must be made to the Treatment Plant or the suitable department for instant restorative action.
Typically speaking, any water-damaged ceiling tiles will need to be changed. Water harmed drywall will need to be examined and perhaps changed. If the carpet has been damp for less than 48 hours and it is damp due to classification 1 water, you should be able to save the carpet if you can completely dry it up as quickly as possible. This will help prevent moisture from remaining in the carpet, adding to the overall moisture content of the indoor air. However, this choice is made on a case by case basis.
Periodically, water will get in structures from the exterior due to improper drainage or especially heavy rains and lousy grading of the land surrounding the home. Water entering the house due to flooding is thought to have the very same classification as sewage-tainted water. Thus, the exact same suggestions for remediation should be used.
Once the clog has been cleared, and you have been notified by the city the issue has been remedied, it should be fine to begin clean-up of the affected areas.
If moisture intrusion damage is found on a wall in the home, the building material or product connected to that wall needs to be disposed of. Furnishings and other products ought to not be positioned directly up against a problem wall if you do not want them to get contaminated.
EH&S should be called to evaluate the afflicted location and to identify the level of removal that is required.
Ceiling tiles should never be painted over to conceal water discolorations or other kinds of damages. Every once-in-a-while, you will run into what is called a “painted pig.” A painted pig is a rundown property that has had a decent coat of paint slapped on to look worthy of selling for more profit.
If ceiling tiles are found to currently be covered in mold, or have a moist, musty smell to them, they should be removed immediately. Remediation needs to be done when the afflicted location is empty. The mold-infested tile ought to be gotten rid of with a minimum amount of disruption and disposed of in a sealed bag to avoid the circulation of any spores in your home.
If large quantities of musty, moldy ceiling tiles are present in the home, a remediation expert should be called to evaluate the circumstances. Remember to make sure this has been done before beginning any type of remediation yourself!
One of the critical tools a home inspector will use while performing an inspection for excess moisture in the home is a moisture meter. A moisture meter is an electronic device that helps in finding different levels of moisture content around a home. Some moisture meters will only work properly on one type of substrate, or building material, such as wood or lumber. Other moisture meters, such as the General Brand MM Series Moisture Meter which I use in my home inspection business, are able to be set to the specific substrate type you want to be measured.
If money is an issue, there are definitely many affordable moisture meters out there, but the issue is that with the lower-priced models, you tend to only have the choice of pin or pinless moisture meters. As a home inspector, I personally prefer to use combination moisture meters as I find them to be much more versatile and handy. But if money is an issue for you, I would definitely suggest the Ryobi E49MM01 Combination Digital Moisture Meter. Ryobi is a solid brand that you can typically trust and rely on to make good, durable products, not to mention it is a multi-substrate combination meter for the price of a single-substrate pin OR pinless moisture meter.
In the northern U.S., moisture intrusion is driven mostly by relatively high indoor humidity levels. When integrated with low outside temperature levels throughout the winter season, moisture intrusion typically occurs. In the southern U.S., the issue is driven by high, outdoor humidity and low indoor temperature throughout the summer months.
The term “vapor barrier” is typically utilized in the home inspection and real estate industry; however, “vapor-diffusion retarder” is most likely more precise, because “barrier” indicates that the product will stop all moisture transfer. However, this is not the case. Any vapor-diffusion retarder product will permit the passage of a minimum amount, or a slight degree of water vapor.
The ability of an offered product to withstand the diffusion of water vapor is determined by systems called “perms,” which measure the materials, or product’s permeability. A perm at 73.4 ° F (23 ° C) is a quantitative measurement of the variety of grains of water vapor going through a square foot of product per hour at a differential vapor pressure equivalent to 1 inch of mercury (1-inch water column). Any product with a perm rating of less than one is thought of like a vapor retarder.
Vapor barriers are a vital part of moisture control for interiors. A vapor barrier is a product, generally a plastic or foil sheet, which withstands the diffusion of moisture through the ceiling, flooring and wall assemblies of a structure, making it a fundamentally different type of product than a vapor-diffusion retarder. Vapor-diffusion retarders are likewise reliable for managing moisture in basements, crawlspaces, and slab-on-grade structures.
You can typically find a myriad of different brands, thicknesses, colors, styles, and what have you else. But for the most part, you should be able to find something at your local Home Improvement Store. Or you can check out what Amazon online stocks below by clicking on either of the two links!

A roofing system leakage might cause the development of noticeable mold nests in the attic that can grow undetected. Roofing penetrations increase the probability of water leakages due to stopped working gaskets, sealants, and flashing. The variety of roofing penetrations might be decreased by a range of innovations and methods, consisting of:
Circulation plumbing lines and a pipe’s components can be the source of significant quantities of moisture intrusion. If the wall is damp and/or tarnished, water damage is likely to be current and/or in currently in development.
One of the most crucial ways of moisture management in the restroom is the exhaust fan. A non-functioning exhaust fan strains the bathroom with wet air. The absence of an exhaust fan must be called out in the inspection report.
It is common for building and design regulations to require damp-proofing of a structure’s walls and foundation. The damp-proofing will be used to extend from the top of the footing to the completed grade. Parging of structure walls ought to be damp-proofed using the following methods:
In summary, moisture can get into a structure in a variety of different methods. High levels of humidity can trigger structural problems in your home and health conditions in your body. It would do manufactured homeowners good here to note that moisture intrusion issues and solutions are very similar for manufactured and site-built homes. New construction homes are being sealed tighter and tighter anymore these days. This is in direct contrast when compared with older homes. Dealing with moisture intrusion in a home has become a much more critical endeavor than ever before. In these new construction homes, once water gets inside the building envelope, water has no way of getting back outside. This can include spills in the home, humidifiers, leaky pipes, and more. Even if it’s “just” water, make sure to clean any spills that happen inside the home immediately and thoroughly.
