How Long to Run an LGR Dehumidifier After Water Damage?
How long you should run an LGR (Low Grain Refrigerant) dehumidifier after water damage depends on the severity of the moisture problem, the type of materials affected, indoor conditions, and drying progress. In most water damage restoration projects, an LGR dehumidifier runs continuously for 3–7 days, but severe cases may require one to several weeks of operation.
After a flood, plumbing leak, or major water intrusion, moisture can penetrate deep into building materials such as drywall, wood framing, flooring, and insulation. Even when surfaces appear dry, hidden moisture can remain inside these materials and create ideal conditions for mold growth. Running an LGR dehumidifier continuously helps remove moisture from both the air and wet structural materials.
Typical Drying Times for an LGR Dehumidifier
Minor water damage (small leaks, limited wet areas):
Usually 2–4 days of continuous operation may be enough if affected materials dry quickly and airflow is good.
Moderate water damage (carpet, drywall, flooring affected):
Typically requires 5–7 days of LGR dehumidification, combined with air movers and regular moisture monitoring.
Severe water damage (flooding, saturated walls, concrete floors, structural materials):
Drying may take 1–3 weeks or longer, especially when moisture has penetrated deeply into building materials.
Should an LGR Dehumidifier Run 24/7?
Yes. During the initial drying stage, LGR dehumidifiers are normally operated 24 hours a day. Continuous operation helps the unit maintain a low-humidity environment and prevents moisture from reabsorbing into materials. Turning the equipment off too early can slow the drying process and increase the risk of mold growth.
However, the drying process should not be based only on the number of operating hours. Professional restoration technicians usually use moisture meters to determine when materials have reached acceptable moisture levels. The equipment can be removed when moisture readings are close to normal for the specific material and environment.
Factors That Affect Drying Time
Several factors influence how long an LGR dehumidifier needs to run:
Amount of water intrusion: More water requires longer drying periods.
Material type: Concrete, hardwood, and dense materials hold moisture longer than carpet or drywall.
Temperature: LGR dehumidifiers work most effectively in warmer conditions, generally above 50°F (10°C).
Air circulation: Air movers improve evaporation and shorten drying times.
Room size and dehumidifier capacity: An undersized unit will require more operating time.
For best results, use an LGR dehumidifier together with high-velocity air movers, maintain indoor humidity below 50% RH, and continue operation until moisture measurements confirm that the affected area is completely dry.
In summary, an LGR dehumidifier should usually run continuously for at least several days after water damage, and it should only be turned off when moisture levels—not just surface appearance—show that the structure has been properly dried.
