Residential mold inspections across San Diego County

From a 600 sq ft condo in Pacific Beach to a canyon-side home in La Jolla — same protocol, same accredited laboratory, same next-day report.

When to test

Six reasons San Diego homeowners call us

A musty smell you can't place

Microbial volatile organic compounds are often detectable long before growth is visible. Air sampling tells you whether the odor is fungal.

A leak, flood or slab issue

Materials that stayed wet longer than 48 hours can support growth inside the assembly even after the surface dried.

Symptoms that improve when you leave

Congestion, headaches, itchy eyes or asthma that lift on vacation and return at home point to an indoor source.

You're buying or selling

An independent report during escrow keeps the negotiation grounded in laboratory data rather than opinion.

Persistent condensation

Coastal marine layer plus poor ventilation gives San Diego bathrooms, closets and north-facing walls a permanent moisture load.

A landlord or tenant dispute

Third-party sampling from a company that does no remediation is the cleanest evidence either side can bring.

Testimonials

Homeowners and agents

I had a client in escrow and we suspected there might be a mold problem. I called a few places and then I found Josh. He was very nice to work with and his pricing was simple and to the point. I made the appointment and he was on time and had the results back to us promptly. He knows his job well and I will definitely use him in the future and would not hesitate to refer him to anyone I know.

Josh recently performed a mold inspection for a property that we were buying. He did an amazing job and gave a clean, honest report. In fact he left me a message summarizing the inspection and sent over the detailed report the next day. Setting up the appointment was easy, no hassle.

Courteous and competitive, they give you clear results without pushing for follow-on work. Unlike many inspectors, they are not involved in repair and are happy to give you just the facts.
