Mold Inspections, Portugal

Mold, moisture & damp inspections you can act on

Independent inspections that confirm what's growing, where the moisture is coming from, and what the humidity readings say, before anyone recommends a fix. Serving properties across mainland Portugal.

Quick Answer A mold inspection combines a visual survey, surface moisture readings, and relative humidity (RH) measurement to confirm cause before remediation, with lab-verified species testing available where the cause isn't clear from readings alone. mold.pt inspections start at €150 for a remote review and €695 for a full in-person diagnostic, covering Lisboa, Porto, the Algarve, and the rest of mainland Portugal.

Our Capabilities

What a mold.pt inspection covers, end to end

The tools and standards behind every report, whether it's a quick remote review or a full on-site diagnostic.

Moisture Mapping

Full-property moisture profiling to trace the actual source, not just the visible symptom.

Moisture Meter Testing

Surface and probe readings at every point of concern, not a single reading for the whole property.

Infrared Thermography

Thermal imaging to spot cold bridging and hidden damp behind walls and ceilings before it's visible.

Mold & Damp Inspections

Visual survey plus lab-verified species testing where the cause isn't clear from readings alone.

Bilingual Reports

Every written findings report delivered in English and Portuguese, no translation delay.

Vetted Local Specialists

Inspections carried out by specialists in mold.pt's network, reviewed for relevant licensing and track record.

Nationwide Coverage

Vetted specialists across mainland Portugal, with remote assessment available everywhere else.

What We Check

Every mold inspection covers moisture, humidity, and cause

Where the moisture is coming from, how long it's likely been there, and what needs to change.

Quick Answer A mold.pt inspection checks surface moisture readings, relative humidity (RH) by room, ventilation and thermal bridging, and visible mold, with lab-verified species testing as an optional add-on.

Moisture & Damp

  • Surface moisture meter readings
  • Rising damp vs. penetrating damp vs. condensation
  • Damp-proof course assessment where relevant

Humidity & Ventilation

  • Relative humidity (RH) readings by room
  • Extraction and cross-ventilation review
  • Thermal bridging and cold-spot identification

Mold & Air Quality

  • Visual survey of affected surfaces
  • Lab-verified species testing (optional add-on)
  • Written report with photos and next steps
Why Get One

An inspection settles what guessing can't

A few situations where an independent mold and moisture inspection is worth the cost before you spend on anything else.

Quick Answer An independent inspection is worth it before a purchase or lease, during a landlord-tenant dispute, when mold recurs after cleaning, or when unexplained symptoms suggest ruling mold in or out directly.
01

Before buying or renting

A damp smell or a fresh coat of paint in the corner isn't proof of anything either way. A moisture and humidity reading is.

02

Landlord or tenant disputes

An independent, dated report gives both sides something factual to work from instead of arguing over who's responsible.

03

Recurring mold after cleaning

If it keeps coming back, the humidity or moisture source was never identified, only the surface was treated.

04

Unexplained symptoms at home

Persistent cough, allergy flare-ups, or a musty smell with no obvious source, worth ruling mold in or out directly.

§
Regulatory

DGS (Direção-Geral da Saúde) guidance links poor indoor air quality, including excess humidity and mould, to aggravation of pre-existing respiratory conditions and allergies, particularly for people with chronic respiratory disease, cardiovascular disease, allergies, children, and the elderly. This is a general, attributed association, not a diagnosis for any individual case. The World Health Organization's guidelines on dampness and mould reach the same conclusion internationally.

Process

Inspect, test, remediate, verify

The same standard every mold.pt case follows, whichever specialist handles it.

Quick Answer mold.pt's four-stage process, Inspect, Test, Remediate, Verify, applies post-remediation clearance testing to confirm humidity and spore counts return to baseline before a case is closed.
01 · INSPECT

Inspect

Visual survey plus moisture and humidity readings across affected rooms.

02 · TEST

Test

Lab-verified species testing where the cause isn't clear from readings alone.

03 · REMEDIATE

Remediate

Matched to the confirmed cause, by a vetted contractor, not a generic callout.

04 · VERIFY

Verify

A follow-up check confirms humidity and spore levels are back to baseline.

Verified

Every case closes with clearance testing, not a visual "looks fine" sign-off. That's what separates a confirmed fix from a hopeful one.

65% RH

Sustained humidity threshold

Held for 48 hours or more, this is the level most consistently linked to active mold growth.

29%

of Portugal's population report a damp home

Living with a leaking roof, damp walls, or rot, the second-highest share in the EU (Eurostat, 2023).

€800–€3,000+

Typical remediation range

Once the cause is confirmed by inspection, cost depends on the affected area and cause.

Pricing

Transparent pricing, published up front

No matching fee, no negotiated quote to get a diagnostic booked. These are the only prices you pay.

Remote Visual Assessment €150

Video call or submitted photos. Preliminary cause assessment.

In-Person Visual Inspection €395

On-site visual assessment with moisture meter spot-checks.

Air Sampling Add-On €395

Spore-count sampling and lab analysis, paired with a Full Diagnostic.

How we're paid: The prices above are the only fees a homeowner pays mold.pt directly, there's no separate booking or matching charge. mold.pt earns a commission from the inspectors and contractors in our network on jobs booked through the platform, not from the homeowner. This is how we can publish fixed pricing instead of a quote that varies by who you happen to reach.
FAQ

Common questions about mold inspections

QWhat does a mold inspection include?
A visual survey of affected areas, moisture readings at the surface, and humidity (relative humidity) measurements across the property. Where the cause isn't obvious from readings alone, moisture mapping and lab-verified species testing confirm it. Every inspection ends in a written report you keep.
QWhat's the difference between a mold inspection and a damp survey?
A damp survey usually focuses on moisture ingress, rising damp, penetrating damp, leaks. A mold inspection covers that plus the biological side: what's growing, how far it's spread, and whether air or surface sampling is warranted. In practice, a proper mold inspection includes a damp assessment as part of finding the cause.
QHow long does a mold or moisture inspection take?
A typical apartment or house takes 45 to 90 minutes on site, depending on size and how many affected areas there are. Lab-verified testing, when it's part of the visit, adds a few days for results before the final report is complete.
QDo you charge a commission or booking fee?
Not to homeowners. You pay only the published diagnostic price listed above, there's no separate matching fee. mold.pt earns a commission from the inspectors and contractors in our network when a job is booked through the platform.
QDo you inspect properties outside Lisbon and Porto?
Yes. We work with vetted specialists across mainland Portugal, including the Algarve, Braga, Coimbra, Aveiro, Cascais, and Setúbal. If you're outside these areas, get in touch, remote assessment by photo and video call is available everywhere.
