Cleaning the Air you Breathe

​No matter how large or small, water damage presents problems that – left untreated – can harm your health.

J&M Keystone, Inc. can help with your mold problem by:


  • Testing the indoor air quality
  • Removing all mold and disposing of it properly
  • Treating all contaminated areas with biocides


Most mold remediation projects are the result of:



  • Excessive humidity levels
  • Improper water damage remediation
  • Poor air circulation Water occurrence


Health Risks:


  • Mold contamination can cause headaches, drowsiness, muscle aches, upper respiratory problems, nose bleeds, or even coughing up blood. This can result in transmitting further illness to people occupying the infected area.


Mold growth can begin within 72 hours of water contact with a building if left unnoticed or improperly extracted. The mold growth may or may not be visible from inside the infected area. The mold contamination may stay hidden within the walls, under the floor, or above the ceiling.

No matter how severe the damage, it’s in the owner’s best interest to employ a professional mold remediation specialist to carry out the restoration process. Insufficient techniques and incomplete removal by unqualified contractors can potentially cause ongoing damage after the treatment and result in more cost to the owner.
