Leak & Moisture Detection

Hidden moisture is the root cause of most mold problems. We locate it precisely—without tearing into walls—so you can fix the source, not just the symptoms.

About

Why Moisture Detection Comes First

Mold needs moisture to grow, and moisture hides. We use non-destructive instruments to map water through walls, floors, and ceilings—and thermal cameras to see temperature anomalies that indicate active leaks or condensation—giving you a precise location before any repair work begins.

Moisture detection helps you:

—Pinpoint the exact source of a leak before demolition
—Map moisture spread behind walls and under flooring
—Identify condensation-prone areas before mold appears
—Confirm repairs were effective after water damage is addressed

Methodology

How We Detect Moisture

Non-destructive tools that locate water without cutting into your property.

We measure the moisture content of walls, floors, and ceilings using both pin-based and non-invasive pinless meters—mapping the full extent of saturation without surface damage.

Best for:

— Drywall, wood framing, and subfloor assessment
— Mapping moisture spread after a water event
— Establishing baseline readings for monitoring

Our thermal cameras detect temperature differentials across surfaces. Water-loaded materials hold heat differently than dry materials, making leaks and saturated zones visible behind finished walls.

Best for:

— Finding active leaks behind drywall without cutting
— Locating plumbing or roof leaks not yet surface-visible
— Identifying condensation zones that feed mold

Every finding is documented with photos, moisture readings, and thermal images. You receive a clear report so contractors, insurers, or property managers can act immediately.

Report includes:

— Moisture readings mapped by room and surface
— Thermal images with annotated anomaly locations
— Probable source identification and next steps

Checklist

When Do You Need Moisture Detection?

Moisture detection is the right first step if:

—You smell mold or dampness but can't find the source
—You've had a plumbing leak, roof leak, or flood
—You're buying a property and want to verify no hidden moisture
—You had water damage and want to confirm the area is fully dry
—Recurring mold keeps coming back after surface cleaning

Moisture detection is often the fastest and most cost-effective way to scope a mold problem before committing to testing or remediation.

Mold inspection San Bernardino FAQ

Call For An Inspection

They can. Many older and lower-income San Bernardino homes use evaporative "swamp" coolers, which cool the air by adding moisture to it — and in a home already sealed against the heat, that extra humidity can condense in closets, ceilings, and wall cavities. If a swamp cooler is oversized, poorly drained, or run alongside air conditioning, it becomes a steady hidden moisture source that feeds mold. An inspection accounts for how the home is cooled, because the fix is often as much about humidity control as it is about any single leak.

Yes. San Bernardino's semi-rural areas, like Muscoy, include many manufactured and mobile homes, which have skirted underbellies, crawl spaces, and duct systems that differ from standard slab houses. Moisture can collect under the home and in the belly wrap out of sight, so these inspections pay special attention to the underside, tie-downs, and any additions built onto the original unit. Catching moisture in the belly and ductwork early is what keeps it from reaching the floor and wall assemblies above.

Yes, even in a dry climate. San Bernardino's summer monsoon can deliver sudden, intense downpours that overwhelm gutters and drainage and drive water into roofs, walls, and low-lying foundations. Because the surrounding climate is so dry, that water is often assumed to have evaporated when in fact it has soaked into materials where mold can start growing. After a monsoon burst that overwhelmed drainage or pushed water inside, a moisture assessment catches what the dry air hides.

Two windows stand out. Late winter and spring bring mountain runoff and snowmelt that raise soil moisture and groundwater on the valley floor, while mid-to-late summer brings monsoon bursts of sudden rain. Homes with swamp coolers or deferred-maintenance roofs and plumbing can carry moisture risk across both seasons, so a check timed to the end of either wet period tends to find problems while they're still small.

Yes. San Bernardino sits at the heart of the Inland Empire's logistics industry, and large warehouses and distribution centers can develop mold without any obvious leak. Their vast flat roofs, big interior volumes, and HVAC systems make roof-drain failures and daily condensation the main culprits, and problems often hide above suspended ceilings or in mechanical areas for months. Commercial inspection here focuses on the roof and its drainage, the HVAC system, and the concealed spaces above ceilings where moisture collects unseen.
