You can’t see mold growing behind drywall. You can’t smell it under flooring. But you’re probably wondering if it’s there especially if you’ve had water damage, noticed a musty smell, or you’re buying an older home in Holmesburg.
Most homes here were built between 1940 and 1969. That’s decades of potential leaks, outdated ventilation, and moisture buildup. Add Philadelphia’s average humidity of 67% year-round, and you’ve got conditions where mold doesn’t just grow it thrives.
Professional mold testing gives you clarity. Air sampling captures airborne spores from hidden colonies. Moisture meters and thermal imaging show you where water is pooling inside walls or under floors. You get lab results in 3-7 days, with documentation that tells you exactly what you’re dealing with and what it means for your health and your home.
Early detection saves money. Mold remediation costs between $1,373 and $3,325 on average, but severe cases can exceed $6,000. Catching it early keeps a small problem from becoming an expensive one. It also protects your property value homes with visible mold or a history of moisture issues can lose 20-37% of their market value.
We’ve been testing and removing mold in Holmesburg and the surrounding Philadelphia area for over 15 years. We’re not a franchise. We’re a local team that responds within 24 hours, shows up when we say we will, and gives you straight answers about what’s happening in your home.
We know this area. We know how basements flood after heavy rain. We know how summer humidity gets trapped in older rowhouses with poor airflow. We know the difference between surface mold you can wipe away and a hidden problem that needs professional attention.
You’ll work directly with our certified inspectors who use moisture meters, infrared cameras, and air sampling equipment not guesswork. We send samples to independent labs, not in-house testing that might have a conflict of interest. And we’ll walk you through the results in plain language, so you know what’s actually wrong and what it’ll take to fix it.
First, we walk through your home and look for visible signs discoloration, water stains, warping, or that musty smell that won’t go away. We check basements, crawl spaces, attics, bathrooms, and anywhere water tends to collect or ventilation is poor.
Then we use detection tools. Moisture meters measure water content inside walls and floors. Thermal imaging cameras show temperature differences that indicate hidden moisture. Infrared technology helps us see problem areas you can’t access without tearing into drywall.
If we find elevated moisture or visible growth, we take samples. Air sampling captures spores floating in your indoor environment. Surface sampling collects material from suspected mold colonies. These samples go to an independent, certified lab for analysis not an in-house facility.
You get results in 3-7 business days. The report includes lab findings, photographs, moisture readings, and our professional interpretation. We’ll tell you what type of mold is present, the concentration levels, whether it’s a health concern, and what remediation steps make sense. If the results show you’re fine, we’ll tell you that too. If there’s a problem, we’ll explain your options without pressuring you into unnecessary work.

You get a full visual inspection of your property, including areas most homeowners don’t think to check. We’re looking at HVAC systems, window seals, plumbing fixtures, and anywhere condensation or leaks create moisture problems.
We use professional-grade equipment: moisture meters, thermal imaging cameras, and infrared detection tools. These aren’t available at hardware stores. They’re designed to find problems before they become visible like elevated humidity levels behind walls or under flooring.
Air and surface samples are collected based on what we find during the inspection. Samples are sent to a certified laboratory for analysis, and you receive a detailed report with photographs, lab results, and moisture readings. The report also includes health implications based on mold type and concentration, so you’re not left wondering what the numbers mean.
Philadelphia’s climate makes mold testing especially important here. Humidity levels hit 72% in September, and the area’s frequent rain keeps moisture levels high for weeks after storms. Local spore counts can exceed 6,000 spores per cubic meter after severe weather a level considered “very high” for respiratory risk. If you’re in an older Holmesburg home with brick construction and limited airflow, your risk is even higher.
We also provide documentation that meets Pennsylvania Department of Health standards and insurance requirements. If you’re filing a claim or selling your home, you’ll have the proof you need.
Most professional mold inspections in the Philadelphia area range from $300 to $600, depending on the size of your home and how many samples need to be tested. Larger homes or properties with multiple suspected areas will cost more because they require additional air or surface samples.
We provide free estimates upfront, so you’ll know the exact cost before we start. No hidden fees. No surprise charges after the report comes back.
Some homeowners skip testing to save money, but that’s a gamble. If you have mold and don’t catch it early, remediation costs jump fast anywhere from $1,373 to over $6,000 depending on how far it’s spread. Testing is the cheaper option when you’re trying to avoid a bigger problem down the road.
Lab results typically come back in 3-7 business days. That’s how long it takes for a certified lab to analyze air and surface samples, identify mold species, and measure spore concentrations.
You’ll get a detailed report that includes lab findings, photographs from the inspection, moisture readings, and a professional interpretation of what the results mean for your health and your home. We don’t just hand you raw data we explain it in plain language.
If we see something during the inspection that raises immediate health concerns like visible black mold or severe water damage we’ll communicate that right away. You won’t have to wait a week to know if there’s an urgent issue. But for confirmed species identification and concentration levels, lab analysis is the only reliable method, and that takes a few days.
You can buy DIY mold test kits at hardware stores for $10 to $50, but they’re not reliable. Most kits only test surface samples, which means they miss airborne spores and hidden growth. They also don’t tell you what type of mold you have or whether the concentration is actually a problem.
Professional testing uses calibrated equipment moisture meters, thermal imaging, air sampling pumps that detect mold you can’t see. We’re trained to know where to look: inside HVAC ducts, behind baseboards, under sinks, in crawl spaces. Those are the places homeowners miss.
The lab analysis matters too. A certified lab identifies the specific mold species and measures spore counts per cubic meter. That tells you whether you’re dealing with common mold that’s not a big deal or toxic varieties that need immediate remediation. DIY kits don’t give you that level of detail. If you’re buying a home, filing an insurance claim, or dealing with health symptoms, you need documentation that holds up and that requires a professional inspection.
Musty smells that don’t go away are the most common sign. If you’ve cleaned, aired out the space, and the odor keeps coming back, there’s likely mold growing somewhere you can’t see.
Visible discoloration on walls, ceilings, or around windows is another red flag especially if it’s black, green, or brown. Water stains, peeling paint, or warping materials also indicate moisture problems, which create perfect conditions for mold growth.
Health symptoms are a big one. If you or your family are experiencing headaches, coughing, skin rashes, or allergy-like symptoms that get worse at home and better when you leave, mold exposure could be the cause. People with asthma or weakened immune systems are especially sensitive.
You should also test after any water damage flooding, roof leaks, burst pipes, or even prolonged high humidity from a broken HVAC system. Mold can start growing within 24-48 hours of water exposure. Even if you dried everything out, hidden moisture behind walls or under flooring can lead to long-term problems. Testing confirms whether you caught it in time or if there’s still an issue.
It depends on what caused the mold. If mold resulted from a sudden, accidental event like a burst pipe, roof damage from a storm, or an appliance leak most homeowners insurance policies will cover testing and remediation.
If mold developed because of long-term neglect, poor maintenance, or ongoing moisture issues you didn’t address, insurance typically won’t cover it. That’s considered a maintenance problem, not a covered peril.
The key is documentation. If you’re filing a claim, you need a professional inspection report with lab results, photographs, and moisture readings that meet insurance standards. That’s what proves the mold is related to a covered event and not something that’s been growing for months or years.
We work directly with insurance companies and provide the documentation they require. We’ll walk you through the claims process and answer questions about what’s covered. Even if insurance doesn’t cover the full cost, catching mold early and getting it properly documented protects your home’s value and keeps a small claim from turning into a bigger one later.
A mold inspection is a visual assessment. We walk through your home, look for visible signs of mold or moisture damage, and use tools like moisture meters and thermal imaging to detect hidden problems. An inspection tells you where mold is likely growing and what’s causing it.
Mold testing goes further. It involves collecting air or surface samples and sending them to a lab for analysis. Testing identifies the specific type of mold, measures spore concentration levels, and confirms whether what you’re seeing (or smelling) is actually mold or something else.
You don’t always need testing. If there’s visible mold and an obvious moisture source like a leaking pipe you can often move straight to remediation. But testing makes sense in a few situations: when you smell mold but can’t find it, when you’re buying or selling a home, when someone in your household is experiencing unexplained health symptoms, or when you need documentation for an insurance claim.
In Holmesburg, where most homes are older and humidity is consistently high, testing is especially useful. It gives you a full picture of your indoor air quality and helps you make informed decisions about remediation so you’re not guessing or overpaying for work you don’t actually need.
