Is unseen mold putting your home—and health—at risk?
Mold problems can go unnoticed for years, but their effects on your property and indoor air quality are serious. At Keystone Castle Inspections, we provide certified mold testing services across the Greater Pittsburgh area, offering detailed lab-backed results and expert insight to help you make confident decisions—whether you're buying, selling, or staying.
What Is Mold Testing—and Why Is It Important?
Mold testing evaluates the presence and concentration of mold spores in the air and on surfaces inside your home. It’s a critical service for identifying environmental health risks and ensuring your home’s air quality is safe for you and your family.
At Keystone Castle Inspections, we test for common mold types found in Western Pennsylvania and assess risk levels based on lab results, visual inspection, and environmental conditions like humidity or water intrusion. While we do not offer mold remediation, our reports give you the clear information needed to take next steps with confidence.
How Mold Impacts Indoor Air Quality
Mold growth is often triggered by moisture—whether from plumbing leaks, poor ventilation, or Pittsburgh’s humid climate. When mold becomes airborne, it can:
Trigger allergy or asthma symptoms
Affect immune-compromised individuals
Lower the overall air quality in your home
Even new or remodeled homes aren’t immune—mold can hide behind drywall, under flooring, or in HVAC systems. That’s why proactive testing is so valuable.
Common Mold Types in Pittsburgh Homes
In homes we inspect across Allegheny, Butler, and surrounding counties, we frequently detect:
Aspergillus – A common indoor mold that can affect respiratory health
Penicillium – Often found on water-damaged materials, this mold spreads quickly and can trigger allergy symptoms
Stachybotrys (Black Mold) – Typically found in damp, poorly ventilated areas; associated with more severe health risks
Our testing identifies these species through lab-confirmed analysis, giving homeowners a clear picture of what they’re dealing with.
The Mold Testing Process
1. Visual Assessment
We start with a walkthrough of the property to identify visible mold and moisture-prone areas like basements, attics, or around HVAC units.
2. Sample Collection
We collect both air and surface samples from key areas of concern. This might include vents, walls, or other areas where mold is suspected but not visible.
3. Lab Analysis
All samples are sent to a certified third-party lab. Results typically arrive within a few business days and include:
Mold species identification
Spore counts
Risk interpretation based on EPA and industry standards
4. Report Delivery
You’ll receive a comprehensive, easy-to-read report within 24 hours of lab results, detailing findings and recommendations. If mold is detected, the report provides clear guidance to discuss with your chosen remediation contractor.
