"Minor initial scheduling hiccups, but on the day of the work Mr. Vance was extremely professional and friendly. He helped us to find the best location for our radon remediation system and start-to-finish the whole install is so much higher quality than I expected. He did an incredible job and the improvement to our air quality is amazing. I am so impressed with the level of detail he put into every aspect. I would definitely recommend!"

"The owner of Valley Mold Remediation came to my home for no cost to check my basement for mold. There were signs of mold at one of our basement windows. He used a tool that checks for dampness and determined the mold was just on the surface and had not spread under the walls. He also checked out double doors for dampness and did not find them to be of concern. He showed me where the seal on our window was gaping, allowing some moisture to cause the mold that I saw and even measured the windows in case I wanted to replace them. (He doesn't do windows, he was just being helpful) I felt comfortable with this man in my home and certain that he was being honest. If I ever do have a mold problem, I will definitely call his company."

"Ms. Raspa has surpassed all my expectations.  She completed a mold test after a remediation project to ensure its success.  Not only did she provide the results promptly, but she has advised us on a number of things including building materials that can contain VOC's, dehumidifiers, and various ways to prevent mold.  She is very professional and makes herself available for consult/ questions!  Would definitely recommend her!

"Bill Hawk is easy to communicate with.  I left a lock-box on the back door, they came out, and did the work while I was at work.  They coordinated with Geller Labs to have them come out and perform a final air test for me.  They did a great job cleaning up.

Mold Testing and Remediation FAQs, answered by experts

Yes, mold can easily grow under your hardwood floors, especially if your house has recently flooded or if there is a leak from a pipe under the floor. Hardwood floors can trap moisture beneath them, creating the perfect environment for mold to grow. Similarly, mold can also grow under your wood floor’s surface paint.

If you see black stuff under your vinyl flooring, it’s probably mold. There is a chance it could just be dirt, dried-out adhesive, or slight water damage, but some of those are causes for mold growth, so you should remove it immediately anyway. In some older homes, it could be black mastic asbestos. If you think it could be this–you guessed it–call a pro.

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.

Mold thrives in high-moisture environments, whether that’s steady leaks or just high condensation. Around the house, common causes of mold include leaky pipes, a leaking roof, high humidity, poor ventilation, a damp basement, rotting food in the fridge, wet clothing and towels not hung properly for drying, a leaking foundation, and a leaky air conditioner.

And, of course, if your home suffers from flood damage, you stand the risk of developing mold in the aftermath. That’s why it’s important to act quickly at the first sign of mold.

While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.
