You’ve seen the stains. You smell something off. Maybe someone in your house can’t stop coughing, or your allergies have been worse since you moved in. You need to know if it’s mold, what kind it is, and how bad the problem really is.
That’s where professional mold testing comes in. We use moisture meters and infrared cameras to find mold hiding behind walls, under floors, and in places you’d never think to check. Then we collect samples and send them to a certified lab for analysis. You get a detailed report showing exactly what’s growing, how much of it there is, and whether it’s a health risk.
No more guessing. No more wondering if that dark spot is just dirt or something worse. You’ll have documentation you can use for insurance claims, real estate transactions, or just peace of mind. And you’ll know exactly what needs to happen next—whether that’s targeted removal, fixing a leak, or improving ventilation.
We’ve been helping Feltonville homeowners figure out their mold problems for years. We know this neighborhood—the older homes built in the 1940s, the humidity that settles in during Philadelphia summers, the basements that never quite dry out.
Our team uses state-of-the-art equipment and works with certified laboratories to give you accurate results. We’re available around the clock because mold doesn’t wait for business hours, and neither do water leaks or flooding. When you call, you’re talking to people who’ve seen hundreds of homes just like yours and know what to look for.
We’re not here to oversell you or scare you into services you don’t need. We’re here to tell you what’s actually happening in your home so you can make the right call.
First, we come to your home for a thorough inspection. We’re looking at visible mold, but also checking areas where moisture tends to hide—behind appliances, around windows, in crawl spaces, near plumbing. We use moisture meters to measure humidity levels in walls and floors, and infrared cameras to spot temperature differences that indicate water intrusion.
If we find signs of mold or moisture problems, we collect air and surface samples. These go to an independent, certified laboratory for analysis. The lab identifies the specific mold species and measures spore counts in your air. This matters because not all mold is the same—some types are more concerning than others.
Within a few days, you get a detailed report. We walk you through what it means in plain language. If remediation is needed, we explain what that involves and give you an upfront estimate. If the problem is minor, we’ll tell you that too. The goal is to give you enough information to make a smart decision about your home and your family’s health.

You get a certified inspector who knows what to look for in Feltonville’s older housing stock. Many homes here were built before modern ventilation standards, which means they’re more prone to moisture buildup. We understand how these homes breathe—or don’t—and where problems typically develop.
Your inspection includes moisture mapping, air quality sampling, and surface testing in suspected areas. We document everything with photos and detailed notes. The laboratory analysis identifies specific mold types, including black mold and other potentially harmful species. You receive a written report that’s clear enough for you to understand but detailed enough to satisfy insurance companies or real estate attorneys.
We also identify the moisture source. That’s critical. Mold is a symptom, not the disease. Whether it’s a leaky pipe, poor drainage, inadequate ventilation, or humidity from Philadelphia’s climate, we find what’s feeding the problem. Because if you don’t fix the source, the mold will just come back after you clean it up.
Most residential mold testing runs between $300 and $600, depending on your home’s size and how many samples we need to collect. A basic inspection with a few air samples costs less than comprehensive testing of multiple rooms with both air and surface samples.
Here’s what affects the price: square footage, number of suspected areas, accessibility of spaces we need to check, and how many lab samples you want analyzed. We offer free initial inspections so we can give you an accurate estimate before you commit to anything.
If you’re dealing with insurance, we can help document everything properly. Many policies cover mold testing when it’s related to a covered event like a pipe burst or storm damage. We work with insurance companies regularly and know what documentation they need.
The on-site inspection typically takes one to three hours, depending on your home’s size and complexity. We’re thorough—checking basements, attics, crawl spaces, behind appliances, and anywhere else moisture might hide.
Lab results usually come back within three to five business days. Some labs offer rush processing if you’re in a time-sensitive situation, like closing on a house sale or dealing with a health emergency.
Once we have results, we schedule a follow-up call or meeting to review everything with you. We’ll explain what the numbers mean, show you where problems are, and discuss your options. The whole process from initial call to having a complete understanding of your situation usually takes about a week.
You can, but here’s what you’re giving up: accuracy, context, and a real plan. Home test kits can tell you if mold spores are present, but they can’t tell you if the levels are actually dangerous, what species you’re dealing with, or where the moisture source is.
Professional testing uses calibrated equipment and certified laboratories. We know how to collect samples properly so results are reliable. We also know what we’re looking at—whether that discoloration is mold, mildew, or just dirt. And we can find hidden mold that you’d never catch with a DIY kit.
Most importantly, we identify why you have mold in the first place. A test kit might confirm you have a problem, but it won’t tell you about the leaking pipe behind your wall or the ventilation issue in your bathroom. Without fixing the source, you’re just going to keep dealing with the same problem over and over.
In Feltonville’s older homes, we most often find Aspergillus, Penicillium, and Cladosporium. These thrive in damp environments and are common in basements, bathrooms, and areas with poor ventilation. Aspergillus can trigger allergic reactions and respiratory issues, especially in people with asthma or weakened immune systems.
Stachybotrys, commonly called black mold, shows up less frequently but is more concerning when it does. It needs sustained moisture to grow, so we typically find it after water damage that wasn’t properly dried, or in areas with ongoing leaks.
The specific type matters because it tells us about the moisture conditions in your home and potential health risks. Some molds are relatively harmless at low levels. Others can cause serious respiratory problems, especially with long-term exposure. That’s why we send samples to a certified lab instead of just guessing based on appearance.
No, you can stay home during testing. The inspection process is non-invasive and doesn’t disturb mold in a way that would increase your exposure. We’re not tearing into walls or stirring up large amounts of spores—we’re carefully collecting small samples for laboratory analysis.
That said, if you have severe mold allergies or respiratory issues, you might be more comfortable stepping out for a few hours. Some people are sensitive enough that even the process of inspecting moldy areas can trigger symptoms.
If we do find significant contamination and recommend remediation, that’s a different story. Depending on the extent of the problem, you might need to stay elsewhere during the removal process. But for testing itself, there’s no need to pack a bag or make other arrangements.
Mold testing tells you what’s growing in your home, how much of it there is, and whether the levels exceed safe thresholds. It gives you objective data about your indoor air quality and identifies specific problem areas. That’s how you know if your home is safe—or what needs to happen to make it safe.
The lab report includes spore counts and species identification. We compare those numbers to established guidelines for indoor air quality. If levels are elevated, we explain what that means for your health and what remediation steps make sense.
Testing also gives you a baseline. If you’ve had mold removed, follow-up testing confirms the remediation worked and spore counts are back to normal levels. If you’re buying a home in Feltonville’s older housing market, testing before you close protects you from inheriting someone else’s moisture problem. It’s documentation that either gives you peace of mind or tells you exactly what you need to fix.
