What Mold Resistant Drywall Installation Includes
Every job includes inspection, containment, removal of contaminated board, framing treatment, new mold resistant drywall, taping, and a moisture check. Paint, trim, and third-party clearance testing are add-ons we can schedule for you.
Containment Setup
6-mil poly barriers at doorways, a negative air machine with HEPA filters, and floor protection. Technicians wear N95 respirators and personal protective equipment so spores stay out of the rest of your home.
Contaminated Board Removal
We cut moldy drywall 12 inches past the visible growth, bag it, and HEPA vacuum the cavity. Studs get an antimicrobial coating and a borate treatment where the moisture reading is high.
Mold Resistant Drywall Install
New mold resistant drywall hung with moisture-resistant screws, taped, and mudded with setting-type compound. Bathrooms get greenboard and a waterproof membrane; basements get a vapor barrier behind the board.
Moisture Verification
Final moisture readings on the new assembly and a last air scrubber pass. You get a clearance summary with the numbers, and we can schedule third-party post-remediation verification before paint.
Mold Resistant Drywall Installation Philadelphia PA
Mold resistant drywall installation Philadelphia PA is a moisture-control service that removes contaminated drywall and replaces it with mold-resistant board, then seals the assembly so future dampness cannot feed a new colony. Standard paper-faced drywall is basically food for mold: the paper backing holds water, and once a wall cavity stays above 60% relative humidity, spores colonize within 24 to 48 hours. We cut out the affected sections, treat the framing, and hang mold resistant drywall in Philadelphia homes that have already fought black mold once.
Philadelphia's rowhouse stock makes this a recurring problem. Brick party walls wick groundwater, 100-year-old plumbing sweats in the summer, and finished basements in Fishtown and South Philadelphia flood every time a sump pump quits. We see the same pattern in Center City condos after an upstairs supply line lets go. If you have been searching for mold resistant drywall installation near me Philadelphia, we handle the tear-out, the antimicrobial coating, and the new board in one visit. Most jobs take one to three days.

Tools and Methods We Use
Tools & Equipment
Thermal imaging camera
Finds hidden moisture behind drywall without cutting. We scan the whole wall and mark the wet zone before we remove a single panel.
Pin-type moisture meter
Confirms the thermal reading with a percentage. We log framing moisture before and after drying, and we do not close a wall above 16%.
Boroscope
A camera on a flexible rod that looks into the wall cavity. We use it to check the back of the board and the condition of the studs before deciding how much to remove.
Negative air machine with HEPA filters
Keeps the work area under negative pressure so spores do not migrate into clean rooms. We run it from containment setup through final cleanup.
Air scrubber
Filters airborne spores during tear-out and after installation. A final pass runs before we take down containment.
Dri-Eaz and Phoenix Restoration Equipment dehumidifiers
Dries the wall cavity and framing after water damage. We run them until moisture readings hit dry standard, which usually takes two to four days.
HEPA vacuum
Removes settled spores from framing, sill plates, and the floor after demolition. Every cavity gets vacuumed before new board goes up.
Methods & Standards
IICRC S520 remediation standard
The industry standard for mold remediation that governs containment, removal, and cleaning. We follow it on every job so the wall is clean before mold resistant drywall goes up.
Antimicrobial coating and borate treatment
After removal we coat exposed framing with an antimicrobial product and apply a borate treatment where moisture readings are high. This stops residual spores from colonizing the studs behind the new board.
Vapor barrier installation
On basement and crawl space walls we install 6-mil poly or a rigid barrier behind the mold resistant drywall. The barrier blocks ground moisture from reaching the board, which is what makes the installation last.
EPA Lead-Safe practices
Most Philadelphia rowhouses were built before 1978, so we follow EPA Lead-Safe work practices during demolition. Containment, wet methods, and HEPA cleanup protect your family and our crew.
When to Install Mold Resistant Drywall
01
A bathroom remodel in Queen Village where the old greenboard was moldy behind the tile.
What we do: We remove the tile and board, treat the studs, and install mold resistant drywall with a waterproof membrane at the tub surround. The new board goes up before the tile setter returns.
→ A bathroom wall that handles steam and splashes without growing mold behind the tile, documented with a moisture reading at the final walkthrough.
02
A finished basement in Mayfair that flooded from a foundation leak during a spring storm.
What we do: We extract the water, dry the cavity, waterproof the leak, and rebuild the lower wall with mold resistant drywall and a 6-mil vapor barrier. The sump pump gets a service check at the same time.
→ The basement stays usable through the next wet season, and the customer has a moisture log to show the wall is dry.
03
An attic bedroom in Mount Airy with condensation mold on the dormer wall.
What we do: We improve the attic ventilation, remove the moldy board, treat the framing, and install mold resistant drywall on the affected wall. A dehumidifier runs during the drying phase.
→ The bedroom is usable again, the musty smell is gone, and the wall is rated for the humidity swings that come with a Philadelphia attic.
04
A commercial office in Center City with a supply line leak over a weekend.
What we do: We work a night shift to contain the area, remove the wet drywall, dry the cavity, and install mold resistant drywall before staff return Monday.
→ The office opens on time with no visible damage and no mold risk in the wall behind the reception desk.
How Mold Resistant Drywall Installation Runs in Philadelphia
Philadelphia is a rowhouse city, and that shapes every mold resistant drywall installation Philadelphia PA job we run. Brick party walls wick groundwater into the adjacent framing. Stone foundations in Manayunk and Roxborough leak after heavy rain. Finished basements in Fishtown, Port Richmond, and South Philadelphia flood when a sump pump fails, and the bottom two feet of drywall soak up the water. In Center City high-rises, the problem is usually a supply line or a neighbor's overflow above you. We size the job to the building: 5/8-inch mold resistant drywall on ceilings for fire rating, greenboard in bathrooms, and a vapor barrier on any wall below grade. Summer humidity pushes indoor relative humidity past 60%, which is the threshold where mold colonizes, so we recommend a dehumidifier in finished basements from June through September. Winter freeze-thaw cycles open foundation cracks, and spring rain finds them. If you need mold resistant drywall services Philadelphia, Pennsylvania homeowners can schedule around a water damage claim, we write the scope in Xactimate format so your adjuster can process it. We serve Philadelphia County ZIPs 19154, 19151, 19150, 19153, 19152, and 19102.
Neighborhoods We Serve
-
Fishtown
Renovated rowhouses with finished basements that flood from sump failures. We install mold resistant drywall with a vapor barrier and check the sump pit on the same visit.
-
Chestnut Hill
Older stone homes with attic condensation problems. Dormer walls and knee walls are the usual spots for mold, and they get mold resistant drywall after ventilation is improved.
-
Center City
High-rise condos where a leak above soaks your ceiling and wall. We coordinate with building management on containment and elevator access before the crew arrives.
-
South Philadelphia
Brick rowhouses with party-wall moisture and old plumbing. We treat the framing and install mold resistant drywall on the shared wall where groundwater wicks through.
Local Conditions We Plan For
-
Summer humidity above 60% indoors
Mold colonizes damp drywall in 24 to 48 hours at that humidity. We recommend dehumidification in finished basements from June through September and install board that tolerates short damp spells.
-
Freeze-thaw foundation cracks
Winter cycles open cracks in stone and brick foundations, and spring rain pushes water into the wall cavity. We waterproof the source before installing mold resistant drywall so the new board stays dry.
-
Pre-1978 rowhouse construction
Lead paint is common in older Philadelphia homes, so demolition follows EPA Lead-Safe practices. Containment and HEPA cleanup add about half a day to the schedule.
Fishtown Basement Wall Rebuild
Problems Mold Resistant Drywall Installation Philadelphia PA Solves
Mold behind drywall is a symptom. These are the problems we actually fix when we install mold resistant drywall in Philadelphia homes and businesses.
Problem
Mold keeps returning after every cleanup
You pay for remediation, paint over the wall, and the spots are back within a season because the paper facing is still feeding the colony.
Our Fix
We remove the contaminated board entirely, treat the framing with an antimicrobial coating, and install mold resistant drywall in Philadelphia so the wall has no food source left. Combined with a vapor barrier, the assembly dries instead of holding water.
Problem
Basement floods and ruins the finished wall
A dead sump pump or foundation leak soaks the bottom two feet of drywall, and you lose the room you paid to finish.
Our Fix
We repair the water source, dry the cavity with dehumidifiers and air movers, then rebuild with mold resistant drywall and a vapor barrier. We also check the sump pump and foundation drainage so the next storm does not undo the work.
Problem
Musty odor that never goes away
The smell means spores are still active somewhere in the wall cavity, even if you cannot see growth on the paint.
Our Fix
We locate the source with a thermal imaging camera, remove the moldy drywall, and treat the cavity with Concrobium or Benefect. After mold resistant drywall installation Philadelphia PA, we run an air scrubber and take air quality samples so you have proof the odor source is gone.
Problem
Insurance claim stalled on documentation
Adjusters deny or delay water damage claims when there is no moisture log, no photos, and no itemized scope for the drywall replacement.
Our Fix
We document everything: thermal images, moisture meter readings, square footage, and an Xactimate-formatted scope. Philadelphia customers use our reports to get the drywall portion of the claim approved without a second inspection.
Why Install Mold Resistant Drywall
Mold resistant drywall does not kill mold. It removes the food source, so a damp wall dries out instead of turning green. Here is what that means for your Philadelphia property.
-
Stops Repeat Growth
Paper-faced drywall feeds mold for years after a leak is fixed. Mold resistant drywall in Philadelphia uses a treated gypsum core and fiberglass mat facing that resist moisture uptake. In a bathroom that stays at 70% humidity, that difference is the line between a clean wall and a colony coming back every spring.
-
Protects Finished Basements
A finished basement in Roxborough or Mayfair represents thousands in framing, insulation, and flooring. When a foundation leak soaks the bottom two feet of drywall, we cut it out and rehang with mold resistant board, then install a vapor barrier. You keep the room instead of gutting it.
-
Lowers Long-Term Cost
Affordable mold resistant drywall installation Philadelphia PA costs a fraction of repeated remediation. One tear-out and rebuild runs $1,200 to $4,500 depending on square footage. Doing it twice because the board was wrong costs double, plus the contents you lose each time.
-
Improves Air Quality
Mold behind walls releases spores into the living space through outlets, baseboards, and HVAC returns. After we install mold resistant drywall and run a HEPA vacuum and air scrubber, spore counts drop. Customers in Germantown and Mount Airy tell us the musty smell disappears within a day.
Mold Resistant Drywall Installation Cost
Typical 2026 pricing in Philadelphia runs $1,200 to $4,500 for a residential mold resistant drywall installation, and a single bathroom wall can come in under $900. The number depends on square footage, board type, how much framing treatment is needed, and whether a vapor barrier or sump work is part of the job. We give you a written scope with a fixed price before we schedule, and we write it in Xactimate format if you are filing a claim.
Typical Investment Range
$900 - $4,500 depending on scope
Doing the job right the first time costs less than remediating the same wall twice. Mold resistant drywall plus a vapor barrier and a fixed water source is what keeps the wall dry for years, not months.
What changes the price
01
Square footage removed
Price scales with the wall area we cut out and replace. A 10-by-12-foot wall is a small job; a full basement perimeter is the largest. We measure on site and list the square footage in the scope.
02
Board type and thickness
Greenboard for bathrooms, 5/8-inch mold resistant drywall for ceilings, and standard 1/2-inch for interior walls. Thicker board and fire-rated assemblies cost more per sheet but are required in some Philadelphia buildings.
03
Framing treatment needed
If the studs read high on the moisture meter, they need an antimicrobial coating and a borate treatment before new board goes up. Heavy growth or rot adds labor and sometimes a carpenter.
04
Vapor barrier or encapsulation
Basement and crawl space walls need a 6-mil vapor barrier or an encapsulation liner behind the board. This is an add-on that prevents the new drywall from wicking ground moisture.
05
Water source repair
We cannot close a wall over an active leak. If a pipe, foundation, or sump pump needs repair first, that work is scoped separately and done before installation.
06
Access and containment
High-rise condos, tight rowhouse stairwells, and occupied homes need more containment and protection. Elevator scheduling and building rules can add time to the job.

Frequently Asked Questions
Real answers to the questions we hear most often from local homeowners and property managers.
How much does mold resistant drywall installation cost in Philadelphia PA?
Most residential jobs run $1,200 to $4,500 in 2026, and a single bathroom wall can come in under $900. Price depends on square footage, whether we are replacing greenboard or standard board, and how much framing treatment is needed. Basements with a vapor barrier and a sump pump tie-in sit at the top of that range. We give you a written number before any work starts.
What is mold resistant drywall in Philadelphia?
Mold resistant drywall is gypsum board with a treated core and either a fiberglass mat or moisture-resistant paper facing. It does not contain food for mold the way standard paper-faced board does. In Philadelphia we install it in bathrooms, basements, kitchens, and any wall that has flooded before. It is not waterproof, so it still needs a vapor barrier and a fixed leak to perform.
Does mold resistant drywall prevent mold in Pennsylvania?
It prevents mold from feeding on the drywall itself, but it does not stop mold from growing on dust, paint, or framing that stays wet. In Pennsylvania's humid summers and freeze-thaw winters, you still need the water source fixed. We pair the board with an antimicrobial coating on the studs and a vapor barrier so the whole assembly stays dry.
How long does mold resistant drywall installation take in Philadelphia?
A single bathroom takes one to two days. A full finished basement runs three to five days including tear-out, framing treatment, hanging, taping, and a moisture check. We schedule around your water damage claim and can start within 48 hours of approval. Drying time for the joint compound adds a day before paint.
