A clear, professional approach to mold remediation & removal — tailored to your Ontario property.
Mystic Relief & Construction starts every mold project in Ontario, CA with a comprehensive inspection. We use thermal imaging and moisture meters to find hidden growth, collect air and surface samples, and wait for lab confirmation before writing the remediation plan.
Our crew sets up full containment in your Ontario home using poly sheeting, zip barriers, and negative air machines with HEPA filtration. This prevents cross-contamination to unaffected areas during removal.
We remove mold-contaminated materials, HEPA vacuum all surfaces, and apply commercial antimicrobial treatments to eliminate remaining spores and prevent regrowth.
Mystic Relief & Construction does not consider the job complete until post-remediation testing confirms safe air quality in your Ontario, CA home. We then restore all removed materials and correct the underlying moisture problem.
Answers to frequently asked mold remediation & removal questions from Ontario property owners.
Mold remediation in Ontario typically costs $1,500 to $9,000 depending on the affected area size, mold species, and accessibility. Small isolated areas cost less, while widespread contamination behind walls or in HVAC systems requires more extensive work. Mystic Relief & Construction provides free inspections with detailed estimates.
Mold removal refers to physically removing mold. Mold remediation is the complete process — containment, air filtration, removal, antimicrobial treatment, moisture correction, and clearance testing. Mystic Relief & Construction provides full remediation in Ontario because removal alone does not prevent recurrence.
Many mold species produce allergens and irritants that cause respiratory issues, headaches, and allergy symptoms. Some species like Stachybotrys produce mycotoxins that pose serious health risks. Professional testing identifies the species, and proper remediation eliminates the exposure risk in your Ontario home.
Common signs include musty odors, visible discoloration on walls or ceilings, recurring allergy symptoms, and recent water damage. However, mold often grows hidden behind walls and above ceilings. Mystic Relief & Construction provides professional mold inspections with moisture mapping and lab-tested air sampling in Ontario.
