Licensed mold assessment

See a stain? Smell something musty? Start with the source.

Mold can be obvious, hidden behind a wall, or confused with an ordinary stain. An assessment helps you understand where moisture is coming from and what work, if any, is needed.

Ask Linnea About an AssessmentWhat to look for

First signs

What should you look for?

Follow the moisture, especially after a leak or a period of high humidity. These signs deserve a closer look, whether or not you can see mold yet.

Visible patches

Speckles, irregular spots, fuzzy growth, or staining on drywall, wood, ceiling tiles, grout, and stored belongings. Growth can look black, gray, green, white, or other colors.

A persistent musty smell

An odor in a closet, basement, cabinet, or room may point to moisture or growth in a place you cannot see.

Evidence of water

Ceiling rings, peeling paint, swollen baseboards, condensation, recurring leaks, wet carpet, or dampness near a foundation can signal conditions that support mold.

Places to check

Under sinks, behind or beside plumbing fixtures, around windows, beneath air-conditioning units, in basements, and near previous roof or foundation leaks.

A photo or color cannot tell you the mold species or whether an area is safe. Some marks are not mold at all. An assessor evaluates the conditions and determines whether further investigation is appropriate.

Real-world examples

Mold does not have one look.

Growth can turn up low on a wall, high in an attic, or only show itself through damp materials. These photos are examples for recognizing a possible concern, not a way to identify a species from a picture.

Several colors in one areaGrowth often concentrates where water collects near the floor. Appearance varies, and color does not establish type or toxicity.
Dark staining across attic roof sheathing above wood rafters
Hidden overhead growthAttics and ceilings can hide growth for years. Finding the moisture source above or nearby matters as much as the stain.

From question to clearance

How does an assessment work?

Each step has a clear owner, so you know who is evaluating the problem, who is fixing it, and how the result is confirmed.

  1. 01Inspect and investigateThe licensed assessor examines the affected area and conditions that support mold. This may include moisture readings. Sampling is considered when it can answer a useful question; it is not automatically necessary.
  2. 02Get a written planIf remediation is called for, the assessor describes the affected areas, likely moisture source, proposed cleanup methods, and criteria for completion in a mold remediation plan.
  3. 03Choose a separate remediatorYou take that plan to a licensed remediation contractor of your choosing. The contractor prepares a work plan and performs the cleanup. Addressing the moisture problem is essential to prevent recurrence.
  4. 04Check the completed workAfter cleanup, the assessor may perform a post-remediation assessment and issue a clearance or final status report. Discuss the expected follow-up before work begins.

Why two distinct roles?

New York separates assessment from remediation.

Under New York Labor Law Article 32, Section 936, a licensee cannot perform both the mold assessment and mold remediation on the same property. The law also prohibits a person from owning an interest in both licensees doing those two jobs on that property.

In practical terms, the assessor identifies and documents the concern and sets out a remediation plan. A separate remediation contractor performs the cleanup. This separation keeps the evaluation and the cleanup in distinct hands.

Common questions

Before you make a call.

Further reading

Can you tell whether it is “black mold” by looking?

No. Mold comes in many colors, and “black mold” is not a species name. A photo cannot tell whether a mold is producing toxins. What matters first is the growth and the moisture feeding it.

Do I need an air test?

Not necessarily. New York's Department of Labor says sampling is rarely recommended as a routine first step; visual inspection and finding the moisture source often provide more useful direction. An assessor can explain when sampling would answer a specific question.

What if I cannot see mold but smell something musty?

Note when and where you notice it and look for leaks, condensation, water stains, or damp materials. An assessment can help locate the moisture source and determine whether further investigation is needed.

Does Linnea do the removal?

No. Linnea's role is assessment and the remediation plan; a separate licensed remediation contractor performs the removal or cleaning when needed.

Your next step

Have a mold or moisture concern?

Describe what you are seeing or smelling and where. Linnea can explain whether an assessment makes sense and what it would cover.
