You can’t see mold spores. You can’t measure chemical compounds with your nose. And you shouldn’t have to guess why your kids keep coughing or why that musty smell won’t go away.
Indoor air quality testing gives you the full picture. We’re talking about lab-grade analysis that identifies exactly what’s floating around your home mold, allergens, volatile organic compounds, particulate matter. The stuff that makes people sick but stays invisible until someone actually tests for it.
Here’s what changes after testing: you stop wondering. You know if there’s a mold problem, where it’s coming from, and how serious it is. You know if your HVAC system is circulating contaminated air. You know whether that renovation project released chemicals into your home. And most importantly, you know what to do next not because someone’s trying to upsell you, but because the data tells the story.
We specialize in historic properties throughout Old City, PA. We understand how 18th-century construction behaves, where moisture hides in older buildings, and why your home’s air quality issues are different from a house built in 1995.
Old City’s colonial-era homes weren’t designed with modern ventilation. Add Philadelphia’s humid summers and aging infrastructure, and you’ve got the perfect recipe for air quality problems. We’ve tested hundreds of properties in this area, and we know what to look for before we even walk through your door.
You’re not getting a franchise crew reading from a script. You’re getting professionals who live and work in this market, who understand the specific challenges your building faces, and who can explain what’s happening in plain terms.
First, we walk through your property and talk about what you’ve noticed symptoms, smells, visible issues, whatever brought you to this point. That conversation matters because it tells us where to focus.
Then we set up air sampling equipment in key areas of your home. We’re collecting samples that get sent to a certified lab for analysis. Depending on what we’re testing for, we might also take surface samples, check humidity levels, and inspect areas where moisture tends to accumulate in older buildings basements, crawl spaces, around windows, near plumbing.
The lab processes everything and sends back a detailed report. We review that report with you and explain what it means in normal language. If there’s a problem, we tell you how serious it is and what your options are. If the air quality is fine, we tell you that too. The goal is clarity, not drama.

Our interior air quality testing covers the contaminants that actually matter in Old City homes. We test for mold spores because older buildings with poor ventilation are breeding grounds. We check for allergens and particulate matter that worsen asthma and respiratory issues. We measure volatile organic compounds that off-gas from building materials, furniture, and cleaning products.
Old City’s building stock comes with specific risks. Aging HVAC systems circulate unfiltered air. Basement moisture seeps into living spaces. Renovations on historic properties can disturb decades of settled dust and contaminants. We account for all of it.
You’ll receive lab results that show exactly what’s in your air and at what concentration. We’ll explain whether those levels are safe, borderline, or need immediate attention. And if remediation is necessary, we’ll walk you through the process without the sales pitch just honest guidance on how to fix the problem and prevent it from coming back.
You need testing if you’re experiencing unexplained health symptoms persistent coughing, sneezing, headaches, or allergy flare-ups that get worse indoors. You need it if you smell mustiness but can’t locate the source. You need it if you’ve had water damage, even if it was cleaned up quickly.
Old City properties have additional risk factors. If your home was built before 1900, has original plaster walls, uses an older HVAC system, or has a basement that feels damp, your indoor air quality is likely compromised. Philadelphia’s humidity creates ideal conditions for mold growth, and historic buildings weren’t designed with modern air circulation in mind.
Testing is also critical during real estate transactions. Pennsylvania regulations require disclosure of known air quality issues, and buyers increasingly request testing before closing. If you’re selling or buying property in Old City, professional testing protects everyone involved.
Comprehensive indoor air testing identifies mold spores, which are the primary concern in older Philadelphia homes. We’re looking at spore counts and types some molds are relatively harmless, others produce toxins that cause serious health problems.
Beyond mold, we test for particulate matter dust, pollen, pet dander, and other allergens that accumulate in poorly ventilated spaces. We measure volatile organic compounds, which are chemicals released by paints, adhesives, cleaning products, and building materials. High VOC levels cause headaches, dizziness, and respiratory irritation.
Depending on your specific concerns, we can also test for radon (common in basements), carbon monoxide (from faulty heating systems), and formaldehyde (often present in older insulation and pressed wood products). The testing protocol depends on your building’s age, your symptoms, and what we observe during the initial inspection.
The on-site portion takes about two to three hours, depending on your property size and how many areas we’re sampling. We’re not rushing through it we need accurate samples from multiple locations to get a complete picture of your indoor air quality.
Lab analysis typically takes three to five business days. We use certified labs that specialize in indoor air quality, not quick-result kits that give you partial information. Once we receive the lab report, we schedule a follow-up consultation to review the findings with you.
That consultation is where the real value happens. We’ll walk through every result, explain what the numbers mean for your health and your property, and discuss your options if problems are identified. You’ll leave that conversation knowing exactly what’s happening in your home and what needs to happen next.
Air quality testing is completely non-invasive. We’re collecting air samples using specialized equipment that doesn’t damage walls, floors, or finishes. There’s no drilling, no cutting, and no disruption to your property’s historic features.
Surface sampling if needed involves gently swabbing areas where we suspect contamination. We’re talking about a cotton swab on a small section of wall or baseboard, not removing material or disturbing original plaster. The process is designed to gather data without impacting your home’s integrity.
Old City homeowners are understandably protective of their properties, especially if they’ve invested in restoration work. We’ve worked in dozens of historic buildings throughout Philadelphia, and we understand the importance of preserving original materials while still getting the information you need to maintain a healthy indoor environment.
First, we explain exactly what the results mean. Not every mold finding requires full remediation, and not every elevated reading means your home is unsafe. Context matters, and we’ll give you an honest assessment of severity before discussing solutions.
If remediation is necessary, we’ll outline the scope of work what needs to be removed, what needs to be cleaned, and what building issues need to be addressed to prevent recurrence. Mold doesn’t grow without moisture, so fixing air quality problems means fixing the underlying causes, not just treating symptoms.
We handle mold remediation and air quality solutions in-house, but you’re not obligated to use our services. You’ll receive a complete report that you can take to any qualified contractor. Our goal is to give you the information you need to make informed decisions about your property and your family’s health.
Testing costs depend on property size, the number of samples needed, and what contaminants you’re testing for. A basic mold inspection with air sampling for a typical Old City rowhome runs differently than comprehensive testing for a multi-unit building or commercial property.
We provide upfront pricing after an initial consultation no surprises, no hidden fees. You’ll know exactly what you’re paying for and why each test matters before we start. Some homeowners only need targeted testing in specific problem areas. Others benefit from whole-house assessment, especially if they’re experiencing symptoms throughout the property.
Here’s what testing isn’t: it’s not an unnecessary expense if you’re dealing with health symptoms or visible moisture issues. Indoor air quality problems don’t improve on their own, and they typically get worse over time. Early detection through professional testing prevents more expensive problems down the road and protects your family from ongoing exposure to harmful contaminants.
