This Oakland California home experienced a leak in the plumbing which upon first appearances did not appear to have caused much damage; however, mold remediation by Environmental CPR was necessary as you will see below.
This laminate hardwood floor may not look damaged but there is a hint of what's lurking under the flooring. There is mold growth at the base of the drywall which indicates that the floor was probably wet and that water probably got under the laminate flooring.
After pulling up one strip of the laminate flooring up against the wall, it is now obvious that there is severe mold growth under the laminate flooring. As you can see in the photo below, the laminate wood floor was installed over a vinyl-plastic cushion and that was installed over some type of felt paper which is now so moldy as to be stuck to the concrete underneath in most areas.
The plastic underlayment and the finish on the laminate flooring both act as moisture barriers so that when water gets below the underlayment, the water will have a very hard time evaporating. Placing a paper product on top of the concrete is a really bad idea since if it gets wet, mold will grow. And since the water really can't evaporate very quickly, the mold will continue to grow as long as the paper remains wet.
In this house in Oakland, CA, we wound up removing all of the laminate wood flooring and cutting the drywall two feet up from the floor. Yes, there was mold in the wall cavity on the wood studs and on the drywall.
With the laminate wood floor and the underlayment pulled up, what remained was a black moldy paper that was stuck right to the concrete. You can see the severe mold growth in the photo below as well as the ducting for the HEPA air filtration device required during mold remediation. The output of the HEPA air filtration device is ducted outside in order to create negative air pressure in the remediation areas so that air is always drawn into the mold remediation area, HEPA filtered, then blown outside; this prevents the spread of mold spores to other areas of the house.

When you hire a mold remediation company, always ask if they will guarantee that their work will pass a mold clearance test by a qualified third-party mold inspector or industrial hygienist.
Just this week I put bids for mold remediation work on three properties that have already had mold remediation work performed but by companies that do not guarantee that the property will pass a mold clearance test when the work is complete.
What does this mean? It means a lot of wasted money and time as the mold will now have to be remediated properly. Doing a poor job on the initial remediation can actually make the situation worse by spreading mold spores throughout the entire house instead of containing it to one room.
This is the case for two of the properties I recently encountered in Oakland, CA, and Berkeley, CA. Both initially had mold in just one room but due to poor work practices, the mold spores were not contained during remediation and released into the home environment and into the HVAC system. What was basically just a one-room remediation effort is now a whole house effort at about triple the cost of what it would have been initially if done properly.
You get what you pay for. If you don't get a guarantee that the remediation work will pass a clearance test then you may wind up doing the remediation effort all over again with a greater scope of work and a much bigger cost!
