One of the most common questions we hear after a water damage event is: "Can't I just run a dehumidifier and some fans?" It's a reasonable question — and the honest answer is: not effectively. Here's why.

The Capacity Gap

A typical consumer dehumidifier removes 30–70 pints of moisture per day. A commercial-grade LGR (Low Grain Refrigerant) dehumidifier removes 150–250 pints per day — and we deploy multiple units on a single job. The difference in drying speed is dramatic, and speed matters enormously in water damage restoration. Every extra day of drying time is another day for mold to grow.

Surface Drying vs. Structural Drying

Consumer fans and dehumidifiers dry the surface of materials — the air you can feel and the surfaces you can touch. They don't dry the inside of walls, the subfloor beneath flooring, or the structural framing. Water migrates into these spaces and stays there, creating hidden moisture that leads to mold growth and structural damage even when the surface feels dry.

Professional drying uses a combination of air movers positioned to create airflow patterns that draw moisture out of structural materials, combined with high-capacity dehumidifiers that capture that moisture from the air. This is a science — the IICRC S500 Standard for Professional Water Damage Restoration defines the specific conditions that must be achieved for proper drying.

Thermal Imaging: Finding What You Can't See

Professional restoration also includes thermal imaging — infrared cameras that detect temperature differences caused by moisture inside walls and under flooring. Consumer drying has no equivalent. Without thermal imaging, you can't know whether your drying efforts have been successful.

The Insurance Angle

Insurance companies increasingly require professional moisture documentation for water damage claims. If you attempt DIY drying and later discover mold or structural damage, your insurance company may argue that the damage resulted from inadequate drying — and deny the claim. Professional restoration with documented moisture readings protects your claim.
