Every inspection includes the full visual and thermal walkthrough, moisture readings, and a written report. Air and surface sampling are quoted separately based on how many rooms you want tested, so you control the cost. Here is what comes standard.
We inspect the basement, crawl space, attic, bathrooms, kitchen, and any room with water history. Every area gets checked for staining, warping, musty odors, and visible growth. This takes 45 to 90 minutes depending on property size.
A thermal imaging camera reveals temperature differences behind walls that signal hidden moisture. A moisture meter confirms the reading on drywall, framing, and subfloor. This is how we find leaks you cannot see.
When we suspect moisture inside a wall cavity, we insert a boroscope through a small access point. It shows us the back of drywall and framing without demolition, so you know whether the problem is surface-level or structural.
We pull outdoor control samples plus indoor air samples, and swab visible growth. Samples go to an accredited lab under chain of custody. Results identify species and compare indoor spore counts to the outdoor baseline.
Your report includes photos, moisture maps, lab results, species identified, and a plain-language summary. It is formatted for homeowners, real estate agents, and insurance adjusters. We send it by email within 24 hours of receiving lab results.
After the report lands, we walk you through it by phone or on site. We explain what the numbers mean, whether remediation is needed, and what the next step looks like. No pressure, no upsell, just clear answers.
Mold Inspection and Testing Philadelphia PA is a diagnostic service that locates moisture problems, confirms whether mold is present, and identifies the species so you know what you are dealing with. We do not just look at the visible spot. We trace the water that fed it, check hidden cavities with a boroscope, and measure moisture content in drywall, framing, and subfloor. Air samples and surface swabs go to an accredited lab, and you get a written report with lab results, photos, and a moisture map.
Philadelphia homes get mold for predictable reasons. Row homes in Fishtown and Kensington deal with crawl space moisture and foundation leaks after heavy rain. Older Center City and Queen Village properties have stone foundations and unsealed basements that sweat all summer. Attic condensation shows up in Chestnut Hill and Mount Airy after cold snaps. If you need professional mold testing near me Philadelphia, that is exactly the call we handle, and we can usually schedule same-day mold testing Philadelphia when you reach us before noon.
Five steps, one visit in most cases, and a written report with lab results. Here is exactly what happens from the first phone call to the final walkthrough.
Schedule
Call or book online — a real human picks up and confirms a 2-hour arrival window.
Diagnose
Licensed tech inspects on-site, then walks you through the cause and your options.
Fix
The job is completed to code and done right the first time — no shortcuts, no surprises.
Guarantee
Every job backed by a written workmanship warranty — and we stand behind it.
Thermal Imaging Camera
Reveals temperature differences behind walls, ceilings, and floors that signal hidden moisture. It finds leaks and wet cavities without cutting open drywall.
Moisture Meter
Confirms moisture content in drywall, framing, subfloor, and insulation. Readings above 16 percent indicate conditions that support mold growth.
Boroscope
Slides into wall cavities through a small access hole to show the back of drywall and framing. It confirms whether growth is surface-level or inside the assembly.
Air Sampling Pump and Cassettes
Pulls measured volumes of indoor and outdoor air for lab comparison. Species and spore counts come back in 24 to 48 hours.
HEPA Vacuum
Captures spores and debris during inspection and remediation without releasing them back into the air. Used with HEPA filters rated for mold work.
Negative Air Machine
Creates pressure differentials that keep spores contained during remediation. We use it when growth is confirmed and removal is underway.
Dehumidifier
Brings humidity below 50 percent to stop mold from spreading. We set Dri-Eaz and Phoenix Restoration Equipment units after inspection when drying is needed.
IICRC AMRT Assessment Protocol
Our inspectors follow IICRC AMRT standards for mold assessment, which cover moisture investigation, sampling strategy, and documentation. That means the report follows an industry-recognized format that insurers and adjusters accept.
Outdoor Baseline Comparison
Every air sample is compared to an outdoor control taken the same day. That tells us whether indoor spore counts are actually elevated or just normal background levels, which prevents false positives and unnecessary remediation.
Moisture Mapping
We record moisture readings across every affected material and map them on a floor plan. The map shows how far moisture has traveled and which materials can be dried versus removed.
Chain of Custody Sampling
Samples are sealed, labeled, and shipped to an accredited lab under chain of custody. That documentation matters if the report is used in a real estate transaction or insurance claim.
OSHA-Compliant PPE
Inspectors wear N95 respirators and personal protective equipment when entering areas with confirmed or suspected growth. We treat every suspect space as contaminated until sampling says otherwise.
01
What we do: We inspect before closing, sample the air and any visible growth, and deliver a report within 48 hours. If remediation is needed, you have hard numbers to negotiate with instead of a vague estimate.
→ You close with full knowledge of the property's condition, or you renegotiate with documentation that holds up.
02
What we do: We check moisture content in walls, framing, and flooring with a moisture meter, then sample the air. If hidden moisture remains, we document it and outline what drying or removal is still needed.
→ You confirm the structure is actually dry, or you catch residual moisture before mold spreads.
03
What we do: We inspect the unit, sample the air and any visible growth, and provide a written report with lab results. The report is formatted for landlord-tenant communication and insurance use.
→ You have a defensible record of the condition and a clear scope for the fix.
04
What we do: We sample the visible growth to identify the species. If it is Stachybotrys, we flag it and outline containment requirements. If it is a common surface mold, we tell you that too.
→ You know exactly what you are dealing with and whether it requires professional remediation or simple cleaning.
Philadelphia's building stock drives where mold shows up. Row homes in Fishtown, Kensington, and Port Richmond often have unsealed crawl spaces that pull ground moisture up into first-floor framing. Center City and Queen Village properties with stone foundations sweat through summer humidity, and basements in 19102 and 19106 stay damp from June through September. Chestnut Hill and Mount Airy attics get condensation after cold snaps, which soaks decking and insulation. We inspect for all of these patterns because we have seen them hundreds of times. If you need mold inspection and testing in Philadelphia PA near me, we bring the right tools for your building type, whether that is a 120-year-old rowhouse or a converted loft in Callowhill. We also handle affordable mold inspection Philadelphia PA for landlords and first-time buyers who need answers without a huge bill. Typical 2026 pricing in this area runs $300 to $650 for a standard inspection with sampling.
Fishtown
Row homes here often have crawl spaces with no vapor barrier, so ground moisture rises into floor framing. We check these spaces first on every inspection.
Center City
High-rises and older conversions in 19102 and 19107 have shared HVAC systems. Duct contamination spreads between units, so we sample registers when odors are reported.
Chestnut Hill
Large older homes with finished attics see condensation on roof decking after cold snaps. We inspect attic sheathing and insulation for moisture and growth.
University City
Rental density is high, and bathroom exhaust fans often vent into walls instead of outside. That traps moisture and feeds mold behind tile and drywall.
South Philadelphia
Many basements here have stone or brick foundations that seep after heavy rain. We check the base of walls and any finished surfaces for elevated moisture.
Summer humidity above 70 percent
Basements and crawl spaces stay damp for months, which lets mold colonize framing and stored items. We see the highest call volume from June through September.
Winter attic condensation
Warm air escaping into cold attics condenses on roof decking and rafters. Growth shows up by February in homes with poor ventilation.
Aging plumbing in pre-1950 rowhomes
Supply lines and drain stacks fail slowly behind walls. We find hidden leaks with thermal imaging before they become visible water stains.
Combined sewer backups after storms
Backups introduce Category 3 water into basements, which carries high mold risk. We inspect and sample after cleanup to confirm no growth took hold.
Most mold calls start with a smell, a stain, or a health symptom. Here are the situations we see most often and how inspection and testing resolves them.
Problem
Odor usually means active growth in a hidden cavity. Ignoring it lets mold spread into framing and insulation, raising remediation costs by thousands.
Our Fix
We use thermal imaging and a boroscope to locate the moisture source, then pull air samples to confirm whether spores are elevated. You get a report that names the species and the exact location, so remediation targets the right area instead of the whole basement.
Problem
Mold colonizes wet drywall and framing within 24 to 48 hours. Waiting a week turns a drying job into a full removal job.
Our Fix
We inspect immediately, measure moisture content in every affected material, and sample the air. If growth has started, we document it for insurance. If it has not, we tell you exactly how long you have to dry the structure and what equipment to run.
Problem
Undocumented mold concerns kill deals or trigger last-minute credit requests that cost sellers thousands.
Our Fix
We perform a mold assessment for real estate transaction Philadelphia buyers and sellers can both rely on. The report includes lab data, photos, and a clear summary. We can send it directly to agents or attorneys and answer follow-up questions within the same business day.
Problem
Headaches, congestion, and coughing that improve when you leave the house often point to airborne spores or HVAC contamination.
Our Fix
We run air quality and mold testing Philadelphia, Pennsylvania including duct and register samples. The report compares indoor counts to outdoor baseline and identifies species. That gives you and your doctor real data instead of a guess about what is in the air.
Testing before remediation tells you what is there, how far it spread, and what it will take to fix. That saves money, protects your family, and gives you documentation that holds up with insurers, buyers, and lenders.
Know Before You Spend
A full mold assessment Philadelphia PA costs a fraction of tearing out walls on a hunch. We confirm active growth, measure how far moisture has traveled, and tell you which materials can be dried versus removed. You get a written scope with lab numbers attached, so every dollar you spend afterward is aimed at a verified problem.
Lab-Confirmed Species ID
Air and surface samples identify genus and relative counts, including black mold testing Philadelphia PA when Stachybotrys is suspected. Results come back in 24 to 48 hours from an accredited lab. That matters when a doctor, landlord, or insurance adjuster asks for documentation instead of an opinion.
Real Estate Deal Protection
A mold assessment for real estate transaction Philadelphia gives buyers and sellers a defensible report before closing. We inspect, sample, and document in one visit, then deliver a written summary you can hand to your agent or attorney. It prevents last-minute credit requests and keeps timelines intact.
Moisture Source Located
Killing mold without fixing the water is wasted money. We use a thermal imaging camera and moisture meter to find the source, whether it is a foundation leak, attic condensation, or a slow supply-line drip behind a cabinet. You leave with the cause named, not just the symptom.
Mold inspection pricing in Philadelphia depends on square footage, how many samples you need, and whether we are checking crawl spaces or HVAC systems. A standard inspection with one or two air samples runs $300 to $650 in 2026. Larger homes, multi-room sampling, and crawl space work push toward the top of that range. You get a flat quote before we arrive, and sampling fees are disclosed upfront so you decide how many you want. We do not bill hourly and there are no trip charges inside Philadelphia County.
Typical Investment Range
$300 - $650 for a standard inspection with sampling; $150 - $350 for clearance testing after remediation
Testing costs a fraction of tearing out walls on a guess. The report tells you what is there, where it came from, and what it takes to fix it. That documentation also supports insurance claims and real estate negotiations, which can save thousands.
What changes the price
Property Size
Larger homes take longer to walk and often need more samples to cover all suspect areas. A 1,200-square-foot rowhome may need two samples, while a 3,000-square-foot twin could need five or six.
Number of Samples
Each air or surface sample carries a lab fee. Most inspections use one outdoor control plus two to four indoor samples. You can add samples for HVAC registers, crawl spaces, or individual rooms.
Crawl Space or Attic Access
Crawl spaces and finished attics take extra time and sometimes require a boroscope to inspect wall cavities. These areas are where we find the most hidden growth, so the extra time is worth it.
HVAC System Testing
If odors worsen when the heat or AC runs, we sample supply registers and return air. That adds samples and time but tells you whether the system is spreading spores through the house.
Real Estate Deadline
Rush turnaround for a closing adds a lab expedite fee. Standard results come in 24 to 48 hours. Expedited results come back the same day in most cases.
Post-Remediation Clearance
Clearance testing after remediation is a separate visit with its own sampling. It confirms the work succeeded and gives you documentation for warranty or insurance purposes.

They found a hidden leak behind our basement wall that two other companies missed. Thermal camera and moisture meter told the story in 20 minutes. Lab results came back in two days with a full report. Worth every dollar.
Yelp ★★★★★4.8
Called on a Monday about a musty smell in our Queen Village rowhome. They were out Tuesday morning, sampled the crawl space and basement, and had results by Thursday. The report was clear and they did not push remediation on us.
BBB ★★★★★4.9
We used them for a real estate transaction in University City. Inspection was thorough, the report was professional, and the lab data satisfied the buyer's attorney. Closing went through without a hitch.
Google ★★★★★5.0
Landlord here. They inspected a tenant complaint, confirmed mold behind the bathroom tile, and gave me a written report I could share with the tenant and my insurance. Fast, professional, and the price matched the quote.
Mold Removal Philly has been inspecting and remediating Philadelphia properties since 2015, which is 11 years of local work. Our inspectors hold IICRC AMRT credentials for mold remediation and IICRC WRT for water damage, and we follow EPA and OSHA safety practices on every job. We have inspected thousands of row homes, twins, and converted industrial lofts across Philadelphia County, from 19102 high-rises to 19154 twins in the Far Northeast. That volume means we have seen how this city's building stock fails, and we know where to look first.
Real experiences from customers who chose our Mold Inspection and Testing services.
“We smelled something musty in the basement for weeks and could not find it. Their inspector used a thermal camera and found a foundation leak behind a finished wall. Air samples confirmed mold, and the report gave us everything we needed for the insurance claim. They were on time, explained everything, and did not try to sell us anything extra.”
Danielle R.
Homeowner, Fishtown
“I had a closing in five days and needed mold testing fast. They got out the next morning, sampled the attic and basement, and had lab results back in 36 hours. The report was clean enough that the buyer's attorney accepted it without a second inspection. That saved the deal.”
Marcus T.
Real Estate Agent, Center City
“A tenant complained about a musty odor in a bathroom. Their inspector found moisture behind the tile and confirmed mold with a surface sample. The written report let me show the tenant exactly what was happening and schedule the fix. Professional, quick, and the pricing was exactly what they quoted on the phone.”

Real answers to the questions we hear most often from local homeowners and property managers.
When inspection confirms active growth, remediation removes it with HEPA filtration, containment, and antimicrobial coating. We handle both steps, so the scope from the report carries straight into the work.
View Mold RemediationStachybotrys needs containment and careful handling. Our inspection identifies it at the species level first, then remediation follows with negative air machines and PPE suited to toxic mold work in Philadelphia homes.
View Black Mold RemovalRow homes, twins, and single-family properties across Philadelphia County get the same inspection protocol. We test first, then remove growth and dry the structure so the problem does not return next season.
View Residential Mold RemovalOffices, restaurants, and retail spaces in Center City and University City need documentation for tenants and insurers. We inspect, sample, and remediate with minimal disruption to business hours.
View Commercial Mold RemovalAttic condensation is common in Chestnut Hill and Mount Airy after cold snaps. Inspection confirms whether growth is active, then we correct ventilation and remove affected sheathing and insulation.
View Attic Mold RemovalStone foundations and unsealed basements in Queen Village and Old City sweat all summer. Testing identifies the species, then we remove growth and address the moisture source with vapor barrier and dehumidification.
