"Quick to respond, thorough, and reasonably priced. They acted conservatively to minimize costs - when other water remediation companies wanted to rip out drywall and counters and have them replaced, they opted to dry out as much of the affected area as possible with minimal damage. In the end, all we had to do after they dried and treated the area was fix our plumbing and replace the flooring for the area."

"In the middle of having my flooring installed, we discovered that I had asbestos in my kitchen and bathroom- the flooring installers walked out of the job immediately. I had 3 companies come and give me bids. San Diego Abatement Services was the most professional and knowledgeable. They scheduled the job the day after I called. They were polite, efficient, and did exactly what they promised to do. They were not the least expensive- but my confidence in a perfect job and the safety of my home was more important. They sent me the certificate of a clean air test so I can now finish my floors!"

"The two gentlemen from Risk Free Serv were knowledgeable and professional. They worked well together and took care of my home as if it were their own. They found mold behind the bathroom vanity and kept me informed of the process as they removed the mold, vanity, and drywall. I appreciated that they didn't try to charge me for unnecessary services as some other companies did."

Mold Testing and Remediation FAQs, answered by experts

Yes, mold in the basement of your home will affect the conditions upstairs. Mold spores can travel through the air and into the supply vents of your home’s ventilation system. It is extremely important to remove any mold in your basement as soon as possible so it doesn’t affect the health of those living in the house.

No, it isn’t. This is one of those things that needs to be dealt with immediately because mold will spread at a rapid rate and can go from just one spot on the wall to a serious health risk in a matter of days. Prolonged exposure can be extremely dangerous, so any mold issues (or even suspected mold) need to be dealt with right away. 

Several factors affect the color of mold, including humidity levels, age of the mold, and amount of light it receives. A patch of mold that starts out green may darken and turn black as it ages. A species of mold may be green if growing in one environment, but be black in another environment. Color usually isn't a reliable way to determine mold species or risk.

The most common sign of a carbon monoxide leak is the visible black soot marks on the walls near your wood stove. An excess accumulation of smoke in other rooms of your home could also indicate that your wood burning stove is leaking carbon monoxide. If you notice either of these signs or are still unsure, it’s best to leave the premises and contact your fire department to check your home’s levels. 

If you find black residue in your toilet tank, chances are it’s caused by manganese deposits from hard water and not mold growth. You can prevent these deposits from damaging your toilet by installing a water softener in your home, which also might improve the quality of your drinking water. You can also remove the deposits inside your toilet tank once every six months or so to prevent them from causing problems with toilet functionality.
