You’ve noticed the smell. Maybe someone in your house can’t stop coughing. Or you’re about to close on a property and the inspector found moisture in the basement.
Here’s what you actually need: answers. Not a visual once-over. Not someone telling you “it looks fine.” You need to know if mold is there, what kind it is, and whether it’s affecting your family’s health.
That’s what mold testing does. We take air samples from inside your home and compare them to outdoor levels. We use moisture meters and thermal imaging to find hidden problem areas. Then we send everything to an independent lab that identifies the exact species and concentration levels.
You get a full report. No guessing. No maybes. Just data you can use to make the right call about remediation, insurance claims, or whether to walk away from a deal.
We’ve been serving South Philadelphia for over 15 years. We’re not a franchise following a script from another state. We know this area the rowhomes with shared walls, the basement moisture issues from being near the Delaware, the humidity that hits every summer and doesn’t let up.
We’ve done over 2,000 mold inspections across the Philadelphia region. We’re certified through InterNACHI as mold inspectors, and we’ve spent more than two decades in construction, so we understand how buildings work and where problems hide.
You’re not getting a salesperson. You’re getting someone who’s seen this before and knows how to handle it.
First, we walk through your property and do a complete visual assessment. We’re looking for visible mold, water stains, discoloration, and any signs of moisture intrusion. We check basements, crawl spaces, attics, HVAC systems, and anywhere else mold likes to grow.
Then we use moisture meters and infrared cameras to measure humidity levels and find hidden moisture behind walls or under floors. High moisture means high risk, even if you can’t see mold yet.
Next, we take air samples from multiple rooms in your home and compare them to an outdoor baseline. This tells us if your indoor air quality is worse than it should be and what types of mold are present. We also take surface samples if we find visible growth.
All samples go to an independent certified lab for analysis. You’ll get a detailed report within 3-5 business days that identifies specific mold species, their concentration levels, and whether they pose health risks. If you need results faster for a real estate closing, we can expedite lab processing for an additional fee.

Every inspection includes a full visual assessment of your property, moisture readings throughout the home, and professional air sampling. We use thermal imaging cameras to detect temperature differences that indicate moisture problems. We test multiple areas to get an accurate picture of your indoor air quality.
South Philadelphia’s climate makes mold testing especially important here. The humidity during summer regularly exceeds 60%, and older rowhomes weren’t built with the ventilation systems we have today. Basements stay damp. Shared walls trap moisture. Poor drainage around foundations leads to seepage.
You also get documentation that works for insurance claims and real estate transactions. If you’re buying a home in South Philadelphia, mold testing gives you leverage to negotiate repairs or walk away if the problem is too big. If you’re selling, it proves your property is clean and prevents deals from falling apart at the last minute.
We respond the same day for urgent situations. If you’ve had a water leak, a pipe burst, or flooding, waiting even 48 hours gives mold time to start growing. The faster you test, the faster you know what you’re dealing with.
Most residential mold inspections in South Philadelphia run between $300 and $600, depending on the size of your home and how many samples we need to take. A typical rowhome inspection falls in the $400-$500 range.
That includes the visual inspection, moisture readings, air sampling, lab analysis, and a full written report. If you need expedited lab results for a real estate closing, that adds to the cost, but standard turnaround is 3-5 business days.
Some companies offer free inspections, but they’re usually tied to remediation services, which means they have a financial incentive to find problems. We keep testing separate so you get unbiased results. You’re paying for accuracy, not a sales pitch.
In South Philadelphia’s humid climate, we most commonly find Aspergillus, Penicillium, and Cladosporium. These species thrive in the moisture conditions created by our warm summers and damp winters.
Aspergillus grows in areas with high humidity and poor ventilation think basements, bathrooms, and around HVAC systems. Penicillium shows up on water-damaged materials like drywall, carpets, and insulation. Cladosporium is often found on wood surfaces and in areas with condensation problems.
Not all mold is dangerous, but some species produce mycotoxins that cause respiratory problems, headaches, and allergic reactions. That’s why lab testing matters. A visual inspection can’t tell you if the mold in your basement is harmless or something that needs immediate remediation. The lab report identifies the exact species and concentration levels so you know what you’re dealing with.
Standard lab analysis takes 3-5 business days from the time we collect samples. The lab needs time to culture the samples and identify specific mold species under a microscope.
If you’re in the middle of a real estate transaction and need results faster, we can request expedited processing. That usually cuts the turnaround to 24-48 hours, but it costs extra because the lab prioritizes your samples.
Once results come back, we’ll walk you through the report and explain what it means. You’ll see exactly which mold species are present, their concentration levels compared to outdoor air, and whether remediation is necessary. We don’t just hand you a report and disappear we make sure you understand what you’re looking at and what your next steps should be.
If you can see mold, you already know you have a problem. The question is whether testing still makes sense, and the answer depends on what you’re trying to accomplish.
Testing tells you what type of mold you’re dealing with and whether it’s producing toxins that could affect your health. It also helps you understand the extent of contamination visible mold is often just the surface issue, and air testing reveals whether spores have spread to other areas of your home.
For insurance claims, you’ll almost always need lab-confirmed results. Insurance companies don’t pay out based on photos or visual inspections alone. They want documentation from a certified lab showing what species are present and at what concentration levels. Testing also gives you a baseline so you can verify that remediation actually worked. After cleanup, we can retest to confirm spore counts are back to normal levels.
It depends on what caused the mold. If it’s from a sudden, accidental event like a burst pipe or storm damage, most policies will cover testing and remediation. If it’s from long-term neglect, poor maintenance, or ongoing moisture problems you didn’t address, they’ll likely deny the claim.
Insurance companies want to see documentation. That means you need a professional mold inspection with lab results showing what species are present and how bad the contamination is. We provide detailed reports that meet insurance requirements, and we can work directly with your adjuster to answer questions and provide additional documentation if needed.
Keep in mind that some insurers won’t cover homes with known mold problems, and a history of mold claims can make it harder to get coverage in the future. That’s why catching problems early matters. If you address moisture issues before mold takes hold, you avoid the insurance headache entirely.
Common symptoms of mold exposure include persistent coughing, sneezing, headaches, difficulty breathing, nose bleeds, and worsening asthma. If multiple people in your household are experiencing these symptoms and they improve when you leave the house, mold could be the cause.
Studies show that up to 21% of asthma cases are linked to mold exposure. Damp indoor environments increase the risk of respiratory symptoms, especially in children and people with existing sensitivities. The problem is that symptoms are often vague and easy to dismiss as allergies or a cold that won’t go away.
Mold testing gives you a definitive answer. If lab results show elevated levels of Aspergillus, Penicillium, or Stachybotrys (black mold), and your family is experiencing health issues, you have a clear connection. That’s when remediation becomes urgent not just to protect your property value, but to protect the people living in your home. The longer you wait, the worse the health effects can get, and some respiratory issues become chronic even after the mold is removed.
