2026 price ranges
Typical Philadelphia ranges,
job by job.
The bottom of each range is a small area on a hard surface with the moisture already fixed. The top is growth that spread inside porous materials across a whole space, with drying and rebuild to follow.
Inspection & testing
Finding the source and the extent
The first visit. Moisture mapped, growth located, and a written report started for the claim, the landlord or the sale.
| Job | Range (USD) |
|---|---|
| Scheduled visual inspection and written estimate | Free |
| Mold inspection with moisture mapping and written report | $250–$500 |
| Air or surface sampling by an independent lab (per sample) | $75–$150 per sample |
| Post-remediation verification (independent clearance testing) | $300–$700 |
Remediation
Containing and removing the growth
Containment, negative air, HEPA filtration, removal of affected materials and antimicrobial treatment to the IICRC S520 standard.
| Job | Range (USD) |
|---|---|
| Small contained area (under 10 sq ft: bathroom ceiling, closet, window) | $500–$1,500 |
| Single room contained remediation (bathroom, bedroom wall, kitchen) | $1,500–$4,000 |
| Basement mold remediation (rowhome basement) | $2,000–$8,000 |
| Attic mold remediation | $2,000–$7,000 |
| Crawl space mold remediation (with vapor barrier) | $1,500–$6,000 |
| Black mold removal (heavy growth or Category 3 water, contained) | $2,500–$10,000 |
| Whole-house or multi-room remediation | $10,000–$30,000+ |
| Commercial mold remediation | $3,000–$25,000+ (scope-dependent) |
Drying & rebuild
Drying the structure and putting it back
Water damage restoration to the IICRC S500 standard, and the drywall, insulation, trim and paint that go back after clearance.
| Job | Range (USD) |
|---|---|
| Water damage restoration (extraction and drying, 2–3 rooms) | $2,000–$6,500 |
| Structural drying equipment (air movers + LGR dehumidifiers) | $50–$125 per unit per day |
| Mold damage repair and rebuild (drywall, insulation, trim, paint) | $1,000–$5,000 per room |
| Contents pack-out, cleaning and storage | $1,000–$5,000 |
Ranges are for Philadelphia in 2026 and include labor, containment, equipment and disposal. The mapped inspection fee is credited against remediation work if you proceed. Prices are consistent across every page on this site.
What moves the price
Six things that decide
where your job lands.
The drivers are simple: how much growth, what it grew on, what is feeding it, how contaminated the water was, how long the drying runs and how much has to be rebuilt.
Square footage of growth
A closet ceiling is a two-day job. A basement where growth runs the length of the party wall behind paneling is a week with a bigger containment and more material out the door.
What it grew on
Drywall, paneling, insulation and cardboard come out. Framing, brick, stone and concrete are cleaned in place. Porous materials cost more because they are replaced, not wiped.
The water source
A dripping supply line is a plumber and a small patch. A flat-roof seam, a party-wall leak or a stone foundation that seeps every storm needs its own fix before remediation holds.
Contamination and access
Sewer water means every porous material it touched comes out regardless of visible growth. Attics and crawl spaces add PPE, time and awkward containment.
Drying days
If the structure is still wet, air movers and dehumidifiers run at a daily rate until the readings say dry. Stone basements and slabs take five to ten days; a bathroom wall takes two.
Rebuild after clearance
New drywall, insulation, trim, flooring and paint sit at the top of each range. Materials that were cleaned and kept sit at the bottom.
Insurance
Some of this is claimable, if the water was sudden and it is documented.
Most Pennsylvania homeowners policies cover sudden and accidental water losses: burst pipes, water heater failures, appliance supply lines and storm damage that opens the roof. Mold that follows one of those losses is usually paid under a mold sublimit, commonly $5,000 to $10,000. Mold from a slow leak, seepage, humidity or deferred maintenance is generally excluded, sewer backup needs a water backup endorsement and flooding needs a separate flood policy.
Where the carrier approves, we bill them directly once the claim is accepted. If you are not claiming, you get the same documentation and an itemized invoice.
What Pennsylvania policies coverWhat the adjuster expects
Included with every job, at no extra charge.
- Dated photos of the water source, the growth and every affected room
- Moisture readings from the first visit and until materials reach dry standard
- Scope explaining why each material was removed or cleaned in place
- Clearance report and itemized invoice on completion
Gradual leaks and humidity are usually excluded. Keep the failed hose or part, note the date you found the water, and photograph everything before it is moved. Proving the loss was sudden is where most mold claims are won or lost.
Pricing questions
Straight answers on cost.
What the inspection covers, what testing costs separately, and why the material and the water source change the number more than the size of the spot.
All questionsHow much does mold remediation cost in Philadelphia?
Most Philadelphia mold remediation jobs land between $500 and $8,000, and the biggest driver is how much material has to come out. A small contained area under 10 square feet, such as a bathroom ceiling, closet or window, runs $500-$1,500. A single room with containment, negative air and removal of affected drywall runs $1,500-$4,000. A rowhome basement runs $2,000-$8,000, an attic $2,000-$7,000 and a crawl space with a new vapor barrier $1,500-$6,000. Whole-house or multi-room remediation starts around $10,000 and can exceed $30,000. Every job gets a written scope and price before work starts, and a scheduled visual inspection with a written estimate is free.
What do a mold inspection and mold testing cost?
A scheduled visual inspection with a written estimate is free. A full mold inspection with moisture mapping and a written report is $250-$500, and that fee is credited against remediation if you hire us for the work. Lab testing is separate: air or surface samples processed by an independent lab run $75-$150 per sample, and a typical rowhome needs three to five samples, so $300-$700 in total. Post-remediation verification by an independent hygienist, the clearance test that confirms the job is done, runs $300-$700. If you can already see or smell mold, EPA guidance says sampling is usually unnecessary, so we will tell you honestly when testing adds nothing but cost.
How much does basement mold remediation cost in a rowhome?
Basement mold remediation in a Philadelphia rowhome runs $2,000-$8,000. The low end covers an unfinished basement with growth on joists, the underside of the subfloor and stored contents, where the work is containment, HEPA vacuuming, antimicrobial treatment and disposal. The high end covers a finished basement in Mayfair or Fox Chase where drywall, insulation and carpet come out, or a basement with a sewer backup where everything porous the water touched is removed. If the stone foundation or slab is still wet, structural drying adds $50-$125 per unit per day, usually for five to ten days. Rebuild after remediation is separate, $1,000-$5,000 per room, and we quote it in writing before anything starts.
How much does black mold removal cost?
Black mold removal with heavy growth or Category 3 water runs $2,500-$10,000 in Philadelphia. The price is higher than standard remediation not because of the color but because of the conditions that produce it: Stachybotrys needs constantly wet cellulose, so by the time it appears the drywall paper, wood or cardboard behind it has usually been soaked for weeks and has to be removed rather than cleaned. Sewer backups add contaminated materials and disinfection to the scope. Under the IICRC S520 standard every type of mold is contained, removed and verified the same way, so a small patch of dark mold on a bathroom ceiling is still a $500-$1,500 job. We price the scope, never the scare.
