Mold Testing San Diego

Mold testing adds laboratory data to inspection observations. Air samples may be interpreted with outdoor comparison samples as appropriate to the sampling plan. Surface swab or tape-lift samples characterize material collected at the specified surface. Results are limited to the method, time and location sampled; they cannot establish whole-building safety or the absence of hidden mold.

For properties in San Diego, mold testing can provide environmental documentation of a suspected mold concern. We agree on the sampling plan and explain laboratory findings alongside site observations.

This page describes mold testing at our main San Diego location, Pro Plus Mold Inspection. Call (619) 935-5995 to schedule.

When it's useful

You suspect mold but can't see it
You need documentation for a landlord, buyer, or insurer
You want environmental documentation about a suspected mold or moisture concern
Remediation is finished and you want clearance results

What we do

1Choose sampling locations based on the inspection
2Collect indoor air samples and outdoor comparison samples as appropriate to the agreed sampling plan
3Collect swab or tape-lift samples from suspect surfaces
4Send samples to a laboratory for analysis
5Explain the lab results in plain language

Inspection scope

A visual check of the area being tested, so samples are taken in the right places
Moisture readings around the area being sampled
Sample locations chosen around your concern, plus an outdoor reference for air samples

Sampling options

Air sampling: outdoor comparison samples may inform interpretation as appropriate to the sampling plan, alongside site observations.
Surface sampling: swab or tape-lift samples characterize material collected at a specified surface; outdoor air comparisons do not apply.
Samples are sent to a laboratory for analysis.

What you receive

A walkthrough of what we found while we're on site, when you're available
A written summary of observations, moisture readings, and likely moisture sources
Laboratory results, if samples were taken
Plain-language next steps, including when no further action is needed

Limitations

We inspect accessible areas only. We don't open walls, move heavy furniture, or remove finishes unless agreed in advance.
Thermal imaging shows temperature differences, not mold. Readings are confirmed with a moisture meter.
Sampling results are limited to the method, time and location sampled; they cannot establish whole-building safety or the absence of hidden mold.
Inspection and testing cannot diagnose illness, determine the cause of symptoms, or rule out a medical condition. Direct health questions to qualified medical professionals.
There are no EPA or federal airborne mold limits. Sampling cannot establish compliance with federal mold standards or guarantee health safety.
Findings reflect accessible areas and conditions during the visit; they cannot guarantee that all hidden mold is found or that future conditions remain unchanged.

Mold Testing questions

What do air sample results tell me?

They show whether the types and amounts of spores indoors look unusual compared with outdoor air at the same time. They don't pinpoint where growth is. That's what the inspection is for.

Can testing tell me if mold is “safe”?

No. There are no universal safe limits for mold spores. Air samples may use outdoor comparisons as appropriate to the sampling plan alongside site observations; surface samples characterize the collected material. Results are method, time and location limited and cannot establish whole-building safety or the absence of hidden mold.
