Mold is a symptom. Water is the cause.

How do I know if I have mold?

Signs include musty odors, visible spots, or recent water damage. Professional testing can confirm it.

In practice, the things that bring people to us are:

• A persistent musty or earthy smell that comes back after cleaning
• Dark, fuzzy or discolored patches: often behind furniture, under sinks, near showers
• Staining that reappears in the same spot after painting over it
• Allergy or asthma symptoms that improve when you leave the house
• Any water damage from the past that was never properly dried

Where it hides

Visible growth is usually the smallest part of the problem. The conditions that produce it, a slow leak, condensation, poor ventilation, exist inside the assembly, so that's where the colony is.

• Wall cavities fed by a pinhole supply-line leak or a failed shower pan
• Under flooring where water wicked in and was never fully dried
• Attics with inadequate ventilation and roof condensation
• Under sinks and behind cabinets: the most common single location we find
• HVAC systems, which then distribute spores to every room

What an assessment involves

1. Visual inspection. Every area you've noticed, plus the places moisture tends to collect that you haven't.
2. Moisture mapping. Thermal imaging and moisture meters locate wet materials behind finishes without opening walls unnecessarily.
3. Source identification. Working out where the water is actually coming from. This is the part that determines whether the fix lasts.
4. Documentation. Photographs, readings and a written assessment of what was found and where.
5. Scope and recommendation. What needs remediation, what needs repair, and what can be left alone.

Where laboratory confirmation is warranted, testing can be arranged. Professional testing is what turns "I think that's mold" into something an insurer or a buyer will act on.

How remediation works

Remediation is containment-first. The affected area is isolated with sheeting and put under negative air pressure so nothing migrates while we work. HEPA air scrubbers run throughout. Non-salvageable porous materials are bagged and removed inside the containment, surfaces are HEPA-vacuumed and treated, and the area is cleared before containment comes down.

Then the moisture source gets repaired: because without that, everything above is temporary.

Your insurance

Mold coverage is the most restricted line in most homeowner policies. It's often covered only when it results directly from a covered sudden loss, a burst pipe you reported promptly, for example, and it's frequently capped at a low limit. Long-term leaks and deferred maintenance are usually excluded.

That makes documentation of the source unusually important. We document what caused it and when, so the claim is presented accurately rather than being denied on a technicality. More on how claims work →
