Vallejo Mold Inspection

Vallejo’s location on the edge of the Bay Area means that buildings in the city are exposed to a moist climate all year round. While this keeps Vallejo much cooler than nearby cities to the east, such as Vacaville and Fairfield, the price of this cool weather is the increased potential for water damage and mold growth.

Insufficiently or improperly sealed homes can result in moisture being absorbed from Vallejo’s foggy, wet air, and into the walls and insulation of your home. Over time, this build up of moisture can create a breeding ground for mold and mildew, leading to the potential for serious structural damage, and as well as the risk of health problems for those who inhabit the affected areas.

IR Environmental is the premier provider of mold inspection and remediation services in Vallejo and throughout the surrounding area. Our inspectors and mold removal specialists are highly trained, and are constantly being educated in new ways that they can improve the effectiveness and thoroughness of the services they provide. If  you suspect that your home has issues with water intrusion or mold growth, please give us a call ASAP. We’ll be happy to explain to you our process, and what to expect. Mold remediation isn’t an easy task–let us help you get the results you desire.

Where does mold usually grow?

Some areas of homes and business buildings are more prone to water damage and mold than other areas. Usually, this is because of exposure to environmental stresses, or proximity to internal sources of water. Here are a few places in your home where you should be keeping a close eye out for water accumulation, mildew, and mold.

1. Basements and foundation crawl spaces – Water runs downhill, as we all know. So, as water accumulates in walls and on floors, it tends to settle into basements and crawlspaces. These areas usually have very poor air circulation, and so water that pools there can’t evaporate away. This can be compounded by drainage issues under and around a house that allows water to seep into these deep spaces.

2. Bathrooms – While both kitchens and bathrooms contain water sources that can spout leaks and create problems, bathrooms tend to be much smaller and more closed up than kitchens. Worse yet, when we close the door to take a shower, that small space quickly becomes filled with extremely humid air, which quickly penetrates any spaces which aren’t adequately sealed, and soaks into wallpaper and other porous surfaces. This is why some of the most obvious mold growth in a home is almost always located on bathroom walls and ceilings.

3. Attics and ceiling spaces – Vallejo isn’t known for its rain, but the frequent fog means that the outsides of homes and buildings are almost constantly exposed to moist air, which is easily absorbed into degraded roofs and beams. This can be compounded by air circulation ductwork running through attic spaces leaking moisture through gaps and cracks. The end result is the perfect place for mold to take hold.



Hi Isaac, thank you so much for coming to my apartment and checking out my children’s rooms for mold/mildew, we weren’t sure if there would be a problem after having their bathroom leak a little. Thankfully there is nothing wrong, but we wanted to be sure. Thanks again

Thank you so much Joe for all you helped us with, when we found out that we had mold we were kind of freaked out. After seeing you guys come in and take care of everything, we didn’t realize it was such a big ordeal, but you guys were great and made it really easy for us. THANK YOU!!!

Experts suspect poor waterproofing in Berkeley balcony collapse” – Los Angeles Times, June 23, 2015

Officials investigating the cause of the balcony collapse in Berkeley that killed six university students have found evidence of poor waterproofing, which led to severe molding and dry rot. Outside experts looking at drawings and photos of the balcony indicated that several design flaws contributed to the incident, including the lack of an angled slope to allow for sufficient drainage, as well as failure to install a waterproof membrane over the top of the plywood floor and support beams.

A photo of the balcony accompanying the Times Article appeared to show evidence of extreme molding throughout the balcony flooring and support beams, to the point of disintegration of the beams.
