MOLD REMEDIATION · COST CALCULATOR

Map the surface. Understand the scope.

Price remediation from the visible affected surface and the materials to replace. Access is recorded, but no publisher prices it. This tool does not identify mold, determine health risk or replace an inspection.

01 / YOUR PROPERTY, YOUR SCENARIONO ACCOUNT REQUIRED

Define the damage.

Visible affected surfaceAn approximate figure, taken from somewhere safe.

sq ft

Affected locationAccess to the affected surface

Materials to replace Each one is priced on the surface it covers, so ticking more never lowers the total.

Walls and ceilings Tick both if the insulation behind the board is wet too.

DrywallInsulation

Damaged wall and ceiling surface, sq ft

Length × height of wall to open up, plus any ceiling area: 30 ft of wall cut 2 ft high is 60 sq ft.

These inputs are assumptions, not an on-site assessment. Unseen conditions are not modeled.

Every row marked PUBLISHED on this page is a national average from a US cost guide; every row marked ASSUMPTION is RestoreWorth’s own modeling choice, with no published source. The result is not a local price and not a quote.

YOUR RANGE FROM PUBLISHED AVERAGESNATIONAL AVERAGES

$1,260–$2,510

Use this range to ask what a quote includes, not to judge whether its price is fair. A national average and a quote for your property are different measurements, and the gap between them is often legitimate.

Insurance. This is a cost of work, not what a policy pays: no deductible, policy limit or exclusion is applied to it.

National figures published by US cost guides, each by its own method: HomeGuide from the estimates homeowners receive from contractors; Angi and HomeAdvisor from surveys of their customers about what the project cost, paired with labor statistics, market research and expert interviews. Captured 2026-09-27. None is a representative sample of invoices, and they carry no adjustment for your state, metro or ZIP. Not reviewed by a restoration professional. Every published figure is checked against the page it cites; the way they are combined is RestoreWorth’s own, and unreviewed.

COHERENCE CHECK · SECOND PUBLISHER

$750–$1,900 — angi.com publishes $10–$25 per sq ft. Our base line reads $1,150–$2,250. angi.com ↗

A second publisher for the same damage type, applied to the same area. Compare it with the base line only, not with the total, and only as a rough coherence check: two publishers rarely draw the scope the same way.

PUBLISHER SCOPE BAND · NOT ADDED

HomeGuide also quotes mold remediation as whole-job bands by size of the affected surface. They are not reproduced here and are never added to the amount above: read them on the publisher’s page and compare them with your whole range. homeguide.com ↗

SECOND PUBLISHER · BAND BY LOCATION · NOT ADDED

Angi also quotes mold remediation as whole-job bands by location. They are not reproduced here and are never added to the amount above: read them on the publisher’s page and compare them with your whole range. angi.com ↗

NOT IN THE AMOUNT ABOVE · AND WHY

Access to the affected surface (open, limited, concealed): no publisher quantifies it. It does not change the amount.
Affected location (bathroom, basement, attic, crawlspace, inside a wall, HVAC): no rate applied here depends on it, so it does not change the amount; Angi’s whole-job bands by location are linked above, not reproduced.

Not included: finding and repairing the cause, contents cleaning, pack-out and replacement, temporary accommodation, permits, laboratory testing, taxes, major structural repair. United States, national averages. No state, metro or ZIP adjustment is applied. The low and high are the publishers' own quoted bounds, not a statistical interval.

Scope first. Price second.

Amounts come from national averages published by homeguide.com and angi.com and captured on 2026-09-27; homeadvisor.com is used as a cross-check only. The damage map itself is schematic: it is not a measurement or a forecast of how damage spreads. The amount cannot see hidden damage, and the tool cannot decide what is safe, salvageable or necessary.

BEFORE ANY QUOTE

What to do first

Leave suspected hidden mold alone. Opening a wall to look can spread it; see the EPA guidance above.
Photograph before anything is moved or thrown away, so an insurer or a contractor can see the damage as it was.
Ask for a line-by-line scope. Read each line against the rows above: what the quote includes, not whether its price is fair.

02 / UNDERSTAND THE SCOPEMITIGATION ≠ RECONSTRUCTION

The surface is a starting point.
Not the whole story.

Remediation and material replacement are priced as separate rows. Access is recorded but not priced, and containment has no row of its own. The tool cannot determine hidden growth, necessary testing or health effects.

Stabilize the situation.

Mitigation stops the damage from spreading. It is separate from the cost of restoring the finished room.

Understand what is affected.

Our material view separates visible finishes from underlying layers. It does not establish which materials can be saved.

See the path back.

Every figure that enters the total keeps its own row: the base rate per square foot, each material replaced, each flat fee that is added, each of our coefficients. A single headline number can hide what is and is not included.
