What is on this surface?
A laboratory can examine the collected material for fungal structures and help distinguish them from other surface deposits.

A small sample.A closer understanding.
A mark on a surface can leave you with questions. Targeted tape sampling helps us look more closely at the material—and explain what the findings mean for your next step.
What the sample can tell us
Look at the material.Keep the bigger picture.
An adhesive lift collects surface material for examination under a microscope. Its value starts with a clear question.
Why is it happening here?
The sample alone does not explain the moisture source, concealed conditions, or the whole room’s air quality. Site observations help complete the picture.
Follow the moistureTesting should answer a useful question. When mold growth is already visible, sampling is often unnecessary before addressing the problem.
EPA guidanceFrom the surface to the explanation
Care in the collection.Clarity in the findings.
A purposeful collection, a traceable sample, and time to understand the result.
Choose the right spot
We review the surface, your concerns, and the question the sample should answer. The location and sampling method are agreed before collection.
Collect & keep it together
A suitable adhesive sampling medium lifts material from the selected spot. The sample is protected for transport and linked to its location in the field record.
Look closer in the lab
Microscopic analysis examines the collected material. We explain the laboratory findings alongside the observations and limits of the inspection.
Small details. A considered approach.
Good collection is more than the tape.
A sample that suits the surfaceClear tape and prepared adhesive slides serve the same focused purpose.
The collector selects a medium compatible with the surface and the laboratory's requirements. A prepared slide can provide a defined collection area and protective holder; the appropriate format depends on the sampling plan.
A clear record of where it came fromThe location is part of the result.
Sample identification, collection notes, and relevant surface observations connect the laboratory result to a specific spot. Different sample locations stay separate so the findings remain traceable.
An explanation you can useUnderstand the findings and the next question to ask.
We explain the laboratory observations, what was sampled, and any limitations. Moisture investigation, additional sampling, or a conversation about corrective work may be appropriate depending on the findings. Confirm scope, costs, and timing before booking.
Before the visit
A little context.A better starting point.
There’s no need to prepare a sample yourself. Let us know what you’ve noticed so we can discuss the appropriate approach.
- 01
Share what has changed
Point out the location, when the mark appeared, and any leak or moisture history.
- 02
Tell us about prior work
Mention recent cleaning, painting, repairs, or a damp surface. These details help us decide whether sampling will be useful.
- 03
Agree on access & scope
Discuss delicate finishes, hard-to-reach areas, the question to answer, and expected costs and timing.
A few good questions
A little more clarity.Before we collect.
When should I choose tape sampling instead of a swab?
Tape sampling can be useful when direct microscopic examination of material on an accessible surface will answer the question. A swab or another method may be more suitable for the surface condition or requested analysis. We discuss the choice with you before collecting a sample.
Which surfaces can be sampled?
Accessible painted walls, trim, and other suitable surfaces may be sampled. Texture, loose material, moisture, and delicate finishes can affect contact with the adhesive. We assess suitability rather than assuming one method fits every material.
Will the tape damage the finish?
Tape sampling usually involves limited contact, but adhesive can lift fragile paint, loose coatings, or delicate finishes. Tell us about sensitive materials so the method and any potential marks can be discussed first.
How much of the surface is sampled?
Each sample represents a small, specific collection area. The size depends on the sampling medium, the laboratory's requirements, and the agreed plan. It does not represent every surface in a room or the whole property.
Can a tape sample find mold behind a wall?
A tape lift examines material collected from the contacted surface. It cannot show what is behind a wall or establish the extent of a concealed issue. Other observations, moisture measurements, or agreed additional access may be needed.
When will I receive the results?
Timing depends on laboratory availability, the requested analysis, and when the sample is received. We explain the expected turnaround and any expedited options before booking; same-day results are not assumed.
What if the surface is wet or was recently cleaned?
Tell us what was done and when. Moisture can affect adhesion, and cleaning or painting may change the material available for collection. We will discuss whether tape sampling is suitable or whether a different approach would be more useful.
