At Bay Area Mold Pros, we complete hundreds of mold inspections around the San Francisco Bay Area every year, and at most of our inspections we determine that ground water is contributing to mold growth within the home being inspected. Ground water issues can be addressed with a combination of solutions such as French drains and sump pumps. These systems seek to divert water away from the perimeter of the home, or to remove it (via electric pump) once it has made its way past the perimeter of the home.
One of the most common issues we identify at Bay Area Mold Pros, when inspecting the home’s exterior, is that one or more rain leaders that are draining the roof water are depositing it directly adjacent to the home’s foundation, often on the “high” side of the lot. This condition is exactly the opposite of what we want to see in terms of how rain water is dealt with. Very large amounts of water can be discharged from these rain leaders, since the rain water that they are collecting might be coming from several hundred square feet of roof surface.
The solution to this condition is actually pretty simple. By connecting the bottom of the rain leaders to flexible or rigid plastic pipes, the water from these rain leaders can be re-directed around the home to another part of the property, ideally, at a lower elevation than the elevation occupied by the home. Although this won’t have any affect on the naturally-occurring ground water that surrounds the home, it will prevent the rain water that is coming from the roof from exacerbating the ground water problem present around the home.
At Bay Area Mold Pros we are experts in the construction-related issues which often underlie mold growth problems.

Tyson holds his own license as a general contractor, and owns his own construction company, Tyson Bruce Construction. Both Rick and Tyson are also Certified Mold Inspectors. But what separates Bay Area Mold Pros from every other mold inspection company in the San Francisco Bay Area is the fact that Rick and Tyson have been building and remodeling homes throughout the San Francisco Bay Area for a combined seventy-plus years. So if you suspect a mold-growth problem in your home in the San Francisco Bay Area, give us a call at Bay Area Mold Pros!
The tenants living in this home in Oakland came home to a flooded basement. They notified their landlord, who sent a plumbing crew out within a day to shut off the water and to repair the broken supply line.
The landlord then had the water pumped out of the basement and brought in fans to dry out the space, assuring the tenants that this would, “…prevent a mold problem.” Well, the standing water dried out, but the tenants believed that they could smell mold and they decided to call out Bay Area Mold Pros for an inspection.
I immediately detected a very strong smell of mold growth, and I took several moisture readings with a variety of meters. I found that both the framing atop the foundation, and the drywall covering this framing, were saturated with water. I could see mold growing on both surfaces, and took air samples throughout the basement.
The lab found high levels of mold spores in every major category, including a fairly high level of marker spores, identified by the lab as Stachybotrys.
This case illustrates what can happen when an inadequate remediation occurs. Many homeowners believe that they can perform their own mold remediation by simply drying out an area that had been subjected to a water-intrusion event. But it’s not that simple. Effective remediations include not just a drying-out process, they involve an appropriate cleaning of all affected surfaces, as well as a proper cleaning of the air through the use of both air scrubbers and machines which utilize negative-air pressure to transfer the mold spores to a location outside of the home.
Property owners who try to save the costs of professional remediations are engaging in a “penny-wise and pound-foolish” approach to what can often be a serious problem. It’s much better to handle any potential mold growth problem as quickly and as effectively as possible as soon as the problem is discovered. Half-measures and money-saving schemes will likely results in what happened in this home…a science project!
