Mold Inspection and Testing

Mold Inspection and Testing

We inspect Northeast Philadelphia homes with thermal imaging cameras and moisture meters to find hidden moisture behind drywall and under flooring.

Mold Remediation

Mold Remediation

Full mold remediation services in Northeast Philadelphia means containment, negative air machines, HEPA vacuuming and antimicrobial coating on affected framing. We remove porous materials that cannot be saved and treat what stays. In Mayfair and Tacony rowhomes, we work tight and keep dust out of living space. Every job ends with clearance testing before we call it done.

Black Mold Removal

Black Mold Removal

Black mold removal in Northeast Philadelphia near me searches usually mean someone found dark growth in a basement corner or under a bathroom sink. We confirm it is actually Stachybotrys or another toxigenic species, then remove it under containment with N95 respirators and full PPE. We treat the source moisture so it does not return. Most single-room jobs take one to two days.

View Details
Residential Mold Removal

Residential Mold Removal

Residential mold removal in Northeast Philadelphia covers everything from a small bathroom patch to a full basement. We work in occupied homes daily, sealing off work zones with plastic and running air scrubbers so your family is not breathing spores. We move furniture, protect floors and clean up before we leave. Most homeowners are back to normal use the same day.

View Details
Commercial Mold Removal

Commercial Mold Removal

Commercial mold removal in Northeast Philadelphia covers retail spaces, offices and light industrial buildings, especially along the Roosevelt Boulevard corridor and near Franklin Mills. We schedule after hours so you do not lose business. Larger jobs use multiple air scrubbers and dehumidifiers running around the clock. We document everything for your insurance carrier and property manager.

View Details
Attic Mold Removal

Attic Mold Removal

Attic mold in Northeast Philadelphia usually shows up on roof sheathing after a bath fan vents into the attic or a roof leak goes unnoticed. We inspect with a boroscope, fix the ventilation or leak, then treat and remove affected sheathing. Bustleton and Somerton homes with mature trees get more roof debris and more attic moisture. We handle both the mold and the cause.

View Details
Basement Mold Removal

Basement Mold Removal

Basement mold removal Northeast Philadelphia PA jobs are our most common call. Stone foundations, old drain tiles and summer humidity make finished basements a target. We remove mold from joists, drywall and stored belongings, then run dehumidifiers until the space is dry. If water is still getting in, we recommend foundation waterproofing or a sump pump before we finish.

View Details
Crawl Space Mold Removal

Crawl Space Mold Removal

Crawl space mold removal in Northeast Philadelphia is common under Somerton and Bustleton ranches. These spaces are low, dirt-floored and often vented to outside humid air. We remove the mold, then install a vapor barrier and encapsulation liner to keep ground moisture out. In many cases we also add a dehumidifier. The result is a dry crawl space that stays dry.

View Details
Bathroom Mold Removal

Bathroom Mold Removal

Bathroom mold in Northeast Philadelphia rowhomes often starts at the caulk line, then spreads behind tile and into the ceiling below. We find the leak with a moisture meter, remove affected drywall or tile backer, treat the framing and rebuild with mold resistant drywall. Exhaust fan problems are a frequent cause. We check the fan and duct it properly while we are there.

View Details
Kitchen Mold Removal

Kitchen Mold Removal

Kitchen mold in Northeast Philadelphia usually traces back to a slow supply line leak, a dishwasher drain or a refrigerator ice maker line. We pull the appliance, open the wall, remove moldy drywall and treat the studs. Then we fix the leak. You get a clean, dry wall cavity and a kitchen you can use again. Most jobs finish in one day.

View Details
HVAC Mold Removal

HVAC Mold Removal

HVAC mold in Northeast Philadelphia spreads spores through every room the system serves. We inspect the air handler, evaporator coil and ductwork with a boroscope. Contaminated flex duct gets removed; metal duct gets HEPA vacuumed, fogged with Benefect and sealed with duct sealant. We also clean the coil and drain pan. This is a job for a licensed tech, not a DIY fogger.

View Details
Drywall Mold Removal

Drywall Mold Removal

Drywall mold removal in Northeast Philadelphia means cutting out what is saturated and saving what is not. We use moisture meters to map the wet zone, then make clean cuts and remove the moldy material under containment. Framing gets HEPA vacuumed and treated with antimicrobial coating. We install mold resistant drywall on the rebuild in basements and bathrooms.

View Details
Water Damage Restoration

Water Damage Restoration

Water damage restoration in Northeast Philadelphia starts with stopping the water and extracting it fast. We use Dri-Eaz and Phoenix Restoration Equipment extractors and dehumidifiers to dry the structure. In rowhomes, water travels through shared walls, so we check the neighbors' side too. We document moisture readings daily until the space hits dry standard.

View Details
Emergency Water Extraction

Emergency Water Extraction

Emergency water extraction in Northeast Philadelphia runs 24/7. When a pipe bursts at 2 a.m. or a sump pump fails during a storm, we roll a truck with extractors and dehumidifiers. We pull standing water, set drying equipment and give you a written moisture log. Fast extraction is the difference between a dry basement and a mold job.

View Details
Flood Cleanup

Flood Cleanup

Flood cleanup in Northeast Philadelphia happens after heavy rain overwhelms the storm sewers, especially in low-lying blocks near the river. We extract water, remove contaminated materials, disinfect with Benefect and dry the structure. Floodwater is Category 3, so anything porous it touched comes out. We document everything for your insurance claim.

View Details
Sewage Backup Cleanup

Sewage Backup Cleanup

Sewage backup cleanup in Northeast Philadelphia is a health job, not a mop job. Older laterals in Mayfair and Holmesburg back up into basements during heavy rain. We extract, remove affected materials, disinfect with RMR-86 and ShockWave, and dry the space. We wear full PPE and dispose of waste per Pennsylvania rules. Do not handle this one yourself.

View Details
Dehumidification Services

Dehumidification Services

Dehumidification services in Northeast Philadelphia keep basements and crawl spaces dry after remediation. We size commercial-grade dehumidifiers to the space, not a big-box unit. In summer, Northeast Philly humidity runs high, and a finished basement without a dehumidifier will grow mold again. We set the unit, dial in the target RH and show you how to maintain it.

View Details
Air Duct Cleaning

Air Duct Cleaning

Air duct cleaning in Northeast Philadelphia removes dust, spores and debris from the duct system. We use HEPA vacuums and rotary brushes, then fog with Benefect where needed. If we find mold inside the ducts, we switch to full HVAC mold removal. This service pairs well with post-remediation cleaning after a basement or crawl space job.

View Details
Air Quality Testing

Air Quality Testing

Air quality testing in Northeast Philadelphia gives you numbers, not opinions. We take air samples and surface swabs, send them to an accredited lab and compare results to outdoor baseline. This is how we confirm a mold problem exists and how we prove it is gone at the end. Landlords use our reports for tenant disputes.

View Details
Odor Removal and Deodorization

Odor Removal and Deodorization

Musty odors in Northeast Philadelphia homes usually mean hidden mold or damp materials. We track the smell to its source, fix the moisture, then treat the space with Benefect and a fogger. Ozone and hydroxyl treatments handle stubborn odors in HVAC systems and crawl spaces. We do not just mask the smell with fragrance.

View Details
Mold Prevention and Moisture Control

Mold Prevention and Moisture Control

Mold prevention in Northeast Philadelphia means controlling moisture before mold starts. We inspect the whole house, check gutters, grading, crawl space vents and bath fans, then give you a written plan. Common fixes include vapor barriers, dehumidifiers, gutter repair and foundation waterproofing. This is the cheapest mold job you will ever buy.

View Details
Crawl Space Encapsulation

Crawl Space Encapsulation

Crawl space encapsulation in Northeast Philadelphia seals the dirt floor and walls with a heavy vapor barrier and encapsulation liner. This stops ground moisture from feeding mold and rot. We seal vents, insulate as needed and often add a dehumidifier. Somerton and Bustleton crawl spaces see the biggest improvement from this work.

View Details
Sump Pump Installation and Repair

Sump Pump Installation and Repair

Sump pump installation and repair in Northeast Philadelphia keeps basements dry during heavy rain and spring thaws. We install primary and battery backup pumps, check the discharge line and test the float. If your pump runs constantly or short-cycles, it needs attention before the next storm. We also install sump liners and covers.

View Details
Foundation Waterproofing

Foundation Waterproofing

Foundation waterproofing in Northeast Philadelphia addresses the source of most basement mold. We seal cracks, apply masonry waterproofing and improve drainage away from the foundation. Stone foundations in Mayfair and Tacony often need repointing and a drainage membrane. This work stops water at the wall instead of letting it in.

View Details
Leak Detection and Repair

Leak Detection and Repair

Leak detection in Northeast Philadelphia uses thermal imaging cameras and moisture meters to find hidden leaks without tearing the house apart. We trace supply lines, drain lines and roof penetrations. Once we find it, we fix it. Finding the leak is the step most mold companies skip, and it is the reason mold comes back.

View Details
Roof Leak Repair

Roof Leak Repair

Roof leaks in Northeast Philadelphia often start at flashing, chimneys and worn shingles after a storm. Water gets into the attic, soaks the sheathing and grows mold. We find the entry point, repair it and treat any attic mold we find. Bustleton and Somerton homes with mature trees see more debris and more roof damage.

View Details
Gutter Cleaning and Repair

Gutter Cleaning and Repair

Gutter cleaning and repair in Northeast Philadelphia prevents the roof-to-basement water path that feeds mold. Clogged gutters overflow at the fascia, soak the wall and dump water at the foundation. We clean, reseal and re-pitch gutters, and add downspout extensions to move water away from the house. Fall is the busy season for this.

View Details
Vapor Barrier Installation

Vapor Barrier Installation

Vapor barrier installation in Northeast Philadelphia stops ground moisture from rising into crawl spaces and basements. We use heavy-duty liner, seal the seams and run it up the walls. This is a core part of crawl space encapsulation and a common add-on to basement mold jobs. It is one of the highest-value fixes you can make.

View Details
Mold Resistant Drywall Installation

Mold Resistant Drywall Installation

Mold resistant drywall installation in Northeast Philadelphia replaces the standard drywall we remove during remediation. We use moisture-resistant board in basements, bathrooms and kitchens, and we keep it off the floor so it does not wick water. This is not a substitute for fixing the leak. It is a smart upgrade for high-risk rooms.

View Details
Post-Remediation Verification and Clearance Testing

Post-Remediation Verification and Clearance Testing

Post-remediation verification in Northeast Philadelphia is how we prove the job is done. We take air samples and surface swabs after cleaning and compare them to the outdoor baseline. If the numbers do not clear, we go back in and clean again. You get a written clearance report for your records, your lender or your tenant.

Common mold problems in Northeast Philadelphia

Northeast Philadelphia has a specific set of conditions that drive mold calls: humid summers, freeze-thaw winters, older housing stock and a lot of basements and crawl spaces. Add heavy rain that overwhelms the combined sewers, and you have a recipe for recurring moisture. Here are the four problems we see most, and how we handle them differently than a general handyman would.

Basement mold after every heavy rain

Older rowhomes in Mayfair, Holmesburg and Tacony have stone or brick foundations and aging drain tiles. When the ground saturates, water finds the path of least resistance and comes through the wall or up through the floor. The basement stays damp for days, and mold starts within 24 to 48 hours.

Crawl space mold under Somerton and Bustleton homes

Vented crawl spaces with bare dirt floors pull humid summer air in, and it condenses on cool joists and ductwork. The dirt floor releases ground moisture year-round. Insulation gets wet, sags and holds water against the wood. This is a slow, hidden problem until the smell reaches the living space.

Attic mold from bath fans and roof leaks

Many Northeast Philadelphia homes have bath fans that dump moist air into the attic instead of outside. In winter, that moisture condenses on cold roof sheathing and grows mold across the underside of the roof deck. Roof leaks from tree debris do the same thing in summer. Both are common in Bustleton and Somerton.

HVAC mold spreading spores through the house

A dirty evaporator coil, a clogged drain pan or a duct system with a leak can grow mold and blow spores into every room. In Northeast Philadelphia, this often follows a basement flood or a long stretch of high humidity. Homeowners notice the smell when the system runs, but they cannot see the source.

Signs you need mold removal in Northeast Philadelphia

Mold does not always announce itself with a big black patch. In Northeast Philadelphia homes, the first sign is often a smell or a symptom, not a visible stain. If you are searching for mold removal in Northeast Philadelphia PA near me, these are the triggers that should get you on the phone. Any one of them is worth an inspection, and two or more means you probably have an active problem.

  • Musty smell in the basement or first floor

    That earthy, damp smell is microbial volatile organic compounds, and it means mold is actively growing somewhere. In Northeast Philly rowhomes it often traces to the basement or a crawl space. If the smell gets stronger when the heat or AC kicks on, the HVAC system may be involved too. Do not wait on this one.

  • Dark spots on basement walls or joists

    Black or greenish spots on the lower block wall, floor joists or stored boxes are classic basement mold. In Mayfair and Tacony, stone foundations wick water and keep the wall damp. Surface wiping does not fix it because the moisture source is still active. You need the leak addressed, not just the stain.

  • Peeling paint or bubbling drywall

    Paint that peels in sheets or drywall that bubbles usually means moisture is pushing from behind. This is common around bathroom walls, under windows and along the base of exterior walls. By the time you see it, mold is often already growing on the back side of the drywall. Open it up and find the leak.

  • Warped or soft flooring near fixtures

    Soft spots near a toilet, tub, dishwasher or refrigerator point to a slow leak that has been running for weeks. The subfloor stays wet, and mold grows underneath where you cannot see it. In Northeast Philadelphia kitchens and baths, this is one of the most common hidden mold sources we find.

  • Allergy symptoms that worsen at home

    If your nose runs, your eyes itch or your cough gets worse when you are home and better when you leave, mold spores in the air are a likely cause. This is especially common in bedrooms above damp basements. Air quality testing gives you a real answer instead of a guess.

What mold removal costs in Northeast Philadelphia

Typical 2026 pricing for mold removal in Northeast Philadelphia runs from about $1,200 for a small bathroom or single-room job to $6,500 or more for a full basement with containment and rebuild. Most rowhome basement jobs land in the $2,500 to $4,500 range. Crawl space encapsulation with mold removal usually runs $4,000 to $8,000 depending on square footage. Emergency calls and sewage backups cost more because of the extra labor and disposal. We give you a written price before we start, and we do not add line items mid-job. If you want affordable mold removal in Northeast Philadelphia without cutting corners, ask for the itemized scope so you can compare apples to apples.

  • Square footage affected โ€” The bigger the contaminated area, the more labor, containment plastic and disposal cost. A single bathroom is a one-day job. A full finished basement with multiple rooms can take three to five days and needs more equipment running the whole time.
  • Water source and category โ€” Clean supply line water is cheaper to handle than sewage backup. Category 3 water from a sewer backup requires full PPE, removal of all porous materials and heavy disinfection with RMR-86 and ShockWave. That adds labor and disposal cost to every Northeast Philadelphia job.
  • Repairs and rebuild โ€” Removing moldy drywall is one price. Rebuilding with mold resistant drywall, trim and paint is another. Some homeowners handle the rebuild themselves to save money. We are happy to do the remediation only and leave the cosmetic work to you or your contractor.

Navigating Northeast Philadelphia: landmarks we use

Northeast Philadelphia is big, and giving directions by street name alone does not always work. Our dispatchers use landmarks to route trucks fast. If you tell us you are near Franklin Mills Mall or off Roosevelt Boulevard, we know which way to send the crew. Pennypack Park is a useful boundary marker for the neighborhoods on the west side of the area, and the Northeast Philadelphia Airport helps us orient the far northeast. This is how we cut response time when you are already dealing with water in the basement.

Franklin Mills Mall

A major retail landmark on the far northeast side. We use it to orient calls in the surrounding commercial and residential blocks and to route trucks coming from the north.

Northeast Philadelphia Airport

A useful reference point for the far northeast corner of the city. It helps us place addresses near the airport industrial area and the neighborhoods around it.

Pennypack Park

The park and its creek corridor run through the middle of the area. We use it as a boundary marker to separate the Mayfair and Holmesburg side from the Somerton and Bustleton side.

Roosevelt Boulevard

The main artery through Northeast Philadelphia. We route most of our trucks along the Boulevard and use it to estimate drive times to any address in the service area.

What Northeast Philadelphia customers say

Averaging 4.9 / 5 across verified reviews.

“We had water in the basement after a storm and found black mold on the joists a week later. The crew from Mold Removal Philly came out the same day, explained exactly what they were doing, and had containment up within an hour. They found the leak, fixed it, and the clearance test passed. Fair price and no upsell.”

Dan R.

Mayfair

“Our crawl space was a mess and the whole house smelled musty. They encapsulated it and added a dehumidifier. The smell is gone and the humidity gauge they installed reads 44%. They were on time, cleaned up after themselves, and answered every question I had without talking down to me.”

M

Maria S.

Somerton

“Called at 11 p.m. when our sump pump died during a storm. They answered, sent a truck, and had the water out before morning. Then they handled the mold that had started on the lower wall. Two visits total and everything was documented for our insurance. I would call them again without hesitation.”

How seasons affect mold removal in Northeast Philadelphia

Mold in Northeast Philadelphia follows the weather. Fall and winter bring roof leaks and condensation, spring brings snowmelt and basement seepage, and summer brings humidity and HVAC problems. Knowing what to watch for each season helps you catch a problem before it spreads. Here is what we see across the year and what you should do about it.

Spring

Snowmelt and April rain push water into basements and crawl spaces across Northeast Philadelphia. Stone foundations weep, sump pumps run constantly and floor drains back up. This is when we get the most basement mold calls of the year. Crawl spaces that stayed borderline all winter tip over into active mold growth.

Tip: Test your sump pump now. Pour a bucket of water into the pit and make sure it kicks on and pumps out. Clear debris from window wells and check that the ground slopes away from the foundation.

Summer

Humidity is the story in July and August. Vented crawl spaces pull in moist air, basements stay damp and HVAC systems run nonstop. Condensation on cold ductwork and pipes feeds mold in crawl spaces and mechanical rooms. Attic mold from bath fans gets worse because the AC is running and the attic is hot and humid.

Tip: Run a dehumidifier in the basement and set it to 50% RH. Change your HVAC filter monthly. If your crawl space has open vents and a dirt floor, that is the season to encapsulate it.

Fall

Leaves clog gutters and downspouts, and the first heavy rain sends water down the exterior walls and into the foundation. Roof leaks from summer storms show up as attic mold now. This is also when we start seeing mold behind siding and around window frames after a wet fall. It is the best time to fix drainage before winter.

Tip: Clean your gutters after the leaves drop and add downspout extensions to move water at least six feet from the foundation. Check the attic for dark staining on the roof sheathing.

Winter

Freeze-thaw cycles open cracks in foundations and masonry, and ice dams push water under shingles and into the attic. Indoor humidity rises because windows stay closed and bath fans run more. Condensation on cold exterior walls and pipes feeds mold in corners and closets. Pipe bursts are a real risk during hard freezes.

Tip: Keep indoor humidity between 30% and 50%. Insulate pipes in unheated spaces and let a trickle run during hard freezes. If you see frost or condensation on walls, ventilate that room and check for a leak.
