Cost guides report a typical water damage restoration job at $1,383 to $6,369 nationally (HomeAdvisor, average about $3,868) and $1,597 to $5,456 for Philadelphia (Angi, average about $3,527). A stone-basement rowhouse can land higher. Your own number is a working estimate until a technician reads the moisture on site, and the emergency-stage price is approved before work starts.
Key takeaways
- HomeAdvisor reports a typical water damage restoration total of $1,383 to $6,369 (average about $3,868), and Angi's Philadelphia page reports $1,597 to $5,456 (average about $3,527). Neither is a quote for your house.
- Per-square-foot rates climb with contamination: cost guides put clean (Category 1) water near $3 to $4, gray (Category 2) near $4 to $6.50 and black (Category 3) at about $7 to $7.50 and up.
- A flooded basement is its own line. Published roundups put the typical total at $2,000 to $7,000, and sewage-contaminated jobs can run well above that.
- Stone, brick and plaster dry slowly, so a basement in an older rowhouse or twin can need more drying days than a drywall room of the same size, and drying days move the bill more than almost anything else.
- Repairs after drying are quoted separately once the materials are dry, and plumbing, roof and water heater replacement are never part of a restoration price.
- Every range from this site's own working-estimate table is labeled as an estimate, and the emergency-stage price is explained and approved before work starts.
What do published cost guides say water damage restoration costs?
HomeAdvisor reports a typical total of $1,383 to $6,369 for water damage restoration, averaging about $3,868. Angi's Philadelphia page reports $1,597 to $5,456, averaging about $3,527. These are averages across many jobs, not what any single house will cost, and they sit well below what a large flooded cellar can reach.
Start with what the published numbers are. They are summaries that cost publishers compile from homeowner reports and contractor surveys, and they smooth together small bathroom leaks and large flooded basements. A house in Jenkintown could sit anywhere inside those ranges, or outside them.
The Philadelphia figure is the closer reference for this area, since it was written for the city market that surrounds Montgomery County. The national figure helps you see whether a number you were given is in the usual neighborhood.
Neither range is a price list. A written estimate from a crew should come with the reasons behind it: how many square feet are wet, what category the water is, which materials are involved and how many days of drying are expected.
| Source | Typical range | Average |
|---|---|---|
| HomeAdvisor, 2026 national guide | $1,383–$6,369 | About $3,868 |
| Angi, Philadelphia page | $1,597–$5,456 | About $3,527 |
| Cost roundups, flooded basement cleanup (HomeAdvisor, Angi, HomeGuide) | $2,000–$7,000 | About $4,000 |
How does the cost change with the category of water?
Cost guides price by square foot, and the rate rises as water gets dirtier. Clean Category 1 runs about $3 to $4, gray Category 2 about $4 to $6.50, and black Category 3 about $7 to $7.50 and up, with sewage cleanup reported at $7 to $15 or more. The category changes what must be removed.
The industry's S500 standard sorts water into three categories. Category 1 comes from a sanitary source, such as a broken supply line. Category 2 is significantly contaminated, such as washing machine discharge. Category 3 is grossly contaminated, such as sewage or rising creek water.
Dirtier water costs more because porous materials that touched it, like carpet pad, drywall and insulation, are usually removed and not dried, and the crew wears protective equipment and cleans and treats surfaces. Water can also get worse as it sits, so a clean-water leak that was found late may be priced like a dirtier one.
Angi's Philadelphia page lists the Category 1 rate at $3.21 per square foot, and its overall Philadelphia range runs from $2.75 to $6.87. HomeAdvisor's national range is $3.50 to $7.50 across all categories.
| Water category | Reported range per sq ft | Publisher |
|---|---|---|
| All categories, national | $3.50–$7.50 | HomeAdvisor 2026 |
| All categories, Philadelphia | $2.75–$6.87 | Angi, Philadelphia page |
| Category 1 (clean) | About $3–$4 (Philadelphia $3.21) | HomeAdvisor and Angi |
| Category 2 (gray) | About $4–$6.50 | HomeAdvisor and Angi |
| Category 3 (black) | About $7–$7.50 and up | HomeAdvisor |
| Sewage cleanup | $7–$15 and up | HomeGuide |
What does a flooded basement cost to clean and dry?
Published roundups put a typical flooded basement cleanup at $2,000 to $7,000, averaging about $4,000, or roughly $3 to $7 per square foot. By category, roundups suggest about $1,500 to $3,500 for clean water, $3,000 to $7,000 for gray and $7,000 to $15,000 for black. Finished space and long drying times push toward the top.
Basements are the normal job in this part of Pennsylvania, so this is the line that matters most for homeowners around Jenkintown. Older homes here usually have full cellars, and a cellar holds water against stone, brick or concrete walls, which dry slowly.
A bare cellar with a concrete floor is usually the cheapest case, since there is little to remove. A finished cellar with carpet, pad, paneling or drywall adds removal, disposal and rebuild work, and the total climbs.
The per-category totals come from roundups such as HomeGuide and are rough. A rising creek or a sewer backup is Category 3 from the start, and the flood damage and sewage cleanup pages explain why.
| Water category | Typical total | What usually drives it |
|---|---|---|
| Category 1 (clean) | $1,500–$3,500 | Extraction, drying days, wet pad and carpet |
| Category 2 (gray) | $3,000–$7,000 | Removal of porous materials, cleaning, drying |
| Category 3 (black) | $7,000–$15,000 | Protective equipment, removal, disinfecting, drying |
What do the individual line items cost?
This site's working estimates for Montgomery County put extraction at $1.00 to $3.50 per square foot, an air mover at $25 to $50 a day and an LGR dehumidifier at $75 to $150 a day. Drying one room for three to five days is estimated at $800 to $2,500. None are sourced prices; each is confirmed on site.
These line items are working estimates carried over from trade ranges seen elsewhere, not figures from a local survey. They are here to help you read an estimate, so a number that is far outside them is worth a question.
The big lever is equipment days. A room dried in three days costs less than the same room dried in six, and masonry and plaster tend to need longer. That is why a crew measures moisture and does not quote a fixed number of days at the start.
Items that depend on what was damaged, such as flood cuts at $3 to $8 per linear foot of wall or drywall replacement at $3 to $7 per square foot, come after the drying is done. They are quoted once the real scope is known.
| Item | Working estimate |
|---|---|
| Emergency inspection and moisture assessment | Free–$200 (often credited if work goes ahead) |
| After-hours, weekend or holiday emergency fee | $100–$300 |
| Standing water extraction (per sq ft) | $1.00–$3.50 |
| Air mover (per unit, per day) | $25–$50 |
| Commercial dehumidifier, LGR (per unit, per day) | $75–$150 |
| Structural drying, one room (3–5 days) | $800–$2,500 |
| Flood cut, wet drywall or plaster 2–4 ft up (per linear ft of wall) | $3–$8 |
| Drywall replacement: hang, tape, paint (per sq ft) | $3–$7 |
| Ceiling water damage repair (one section, including paint) | $500–$1,800 |
| Antimicrobial application (per sq ft) | $0.50–$2.00 |
| Water heater or appliance leak cleanup (one area) | $800–$3,000 |
| Emergency board-up or roof tarp | $250–$1,200 |
| Contents pack-out, cleaning and storage | $1,000–$6,000+ |
What pushes a stone-basement rowhouse job above the average?
Dense materials that dry slowly, limited access and long contact time push an older rowhouse or twin basement above the published averages. Rubble-stone and brick walls, plaster ceilings and hardwood over joists all hold moisture. A narrow cellar stair and no side yard also add handling time, since equipment has to be carried through the house.
Stone and brick walls take in water and release it slowly. A cost guide written for a drywall house does not reflect the extra drying days a masonry wall can need, so a figure that looks high for your square footage may simply be reflecting that.
Plaster ceilings above a flooded cellar, or on the floor above a leak, are heavier and slower to dry than drywall. If one has to be removed, the repair is also a plastering job and not a hang-and-tape job.
Access matters too. In a row or twin, equipment goes in through the front door and down narrow stairs, and pump hoses run out the same way. That is slower than a ground-level garage, and it shows up in labor. The rowhouse and twin page covers how that work goes.
- Water that sat for days before anyone called
- Finished walls, carpet or paneling in the cellar
- Category 2 or 3 water instead of clean water
- A large footprint with several rooms wet
- Asbestos or lead testing before demolition in a pre-1980s house
What is not in a restoration price, and what about insurance?
A restoration price covers water removal, drying and, if quoted, repairs after drying. It does not cover plumbing repair, water heater replacement, roof work, radon or abatement, which other licensed trades handle. Whether insurance pays any of it is decided by your insurer under your own policy, and no price on this page implies that it will.
A plumber fixes the pipe, a roofer fixes the roof, and a waterproofing contractor deals with why a cellar takes in water. Those are separate bills from separate trades, and they matter as much to the final cost as the drying does.
Insurance is a separate question that depends on the cause. Sudden and accidental damage such as a burst pipe is often covered, and long-term seepage usually is not. Standard homeowners policies exclude flood, and sewer or sump backup is typically covered only with an endorsement. Your own policy and your own agent hold the real answers.
What the crew can do is document the job. You receive moisture readings, photos and a drying log, which are useful for any claim. Coverage is a decision for your insurer, not for the crew or this website.
How do you read a written estimate?
A good estimate separates the emergency stage from repairs, names the water category, lists equipment and expected drying days, and says what the price assumes. Ask what changes the number. Pennsylvania requires most home improvement contractors to register with the Attorney General and put jobs over $500 in writing, so ask for the registration number.
The emergency stage is extraction, removal of materials that cannot be saved and drying setup. That price is explained and approved before work begins. Repairs such as drywall, plaster, trim and flooring come after drying and are quoted when the real scope is clear.
Read for assumptions. If the estimate assumes three drying days, ask what happens when readings say four. If a flood cut is priced per linear foot, ask how high it will go and why.
You can look up a contractor's registration on the Attorney General's site, and you can ask any company which certifications its technicians hold. For work beyond about $500, the contract should be in writing and carry the registration number.
Frequently asked questions
Is the price per square foot the price I will pay?
Not exactly. A per-square-foot rate is a way cost guides summarize jobs, and it shifts with water category, materials and drying time. Your actual total comes from a walkthrough with a moisture meter, and the emergency-stage price is approved before work starts.
Why do two estimates for the same basement differ so much?
They may assume different drying days, different categories of water or different amounts of removal. Ask each company what it measured, what it assumes and what would change the price. A written estimate should explain those points.
Do you quote over the phone?
You can get a general idea of how pricing works on a call, but a firm figure needs someone to read the moisture on site. A price given sight unseen is a guess. You see and approve the emergency-stage price before anything begins.
Will insurance pay for water damage restoration?
Only your own policy and your own insurer can answer that. Burst pipes are often covered, long-term seepage usually is not, and flood and sewer backup need separate coverage. The crew can give you photos and readings for your claim. Ask your agent before assuming either way.
Does the price include fixing the leak?
No. A licensed plumber repairs pipes and fixtures, and a roofer repairs a roof. Restoration covers the water, the drying and the repairs to what was damaged, which is why those trades are separate bills.
Why does drying take longer in an old stone basement?
Stone, brick and plaster hold water and release it slowly. A masonry wall can stay damp long after the floor looks dry. A crew uses meters to decide when drying is done, which can mean more equipment days than in a drywall room.
