The Source Is Above the Stain Not at the Stain
A water stain on a ceiling in a Las Vegas home means water has entered the ceiling assembly from above. Finding the source is not always straightforward water travels along framing members and sheathing before dropping, which means the entry point and the visible stain are often in different locations. The stain tells you water is present. It does not tell you where the water came from or how far it has traveled in the assembly before dropping to the ceiling surface.
The most common sources of ceiling water damage in Las Vegas are AC condensate line failures or pan overflows in attic-mounted air handlers, plumbing fixture or supply line failures on the floor above, roof leaks that travel along sheathing, and bathroom exhaust fans that have been leaking condensate into the ceiling for extended periods. Each source creates a different pattern in the ceiling assembly and requires a different repair.
Why the Visible Stain Understates the Damage
By the time a water stain is visible on a ceiling surface, the ceiling material above the drywall the insulation, the framing, and possibly the subfloor or sheathing above has already been wet. The stain appears when the drywall is saturated enough for moisture to show at the surface. Thermal imaging of the ceiling often shows moisture extending significantly beyond the visible stain in every direction. A homeowner in Henderson had a stain about eighteen inches across. Thermal imaging showed moisture extending four feet in one direction toward the HVAC handler location. The condensate line had been dripping intermittently for weeks.
What We Do
We identify the source, map the full extent of moisture with thermal imaging, and stop the source before drying begins. We assess whether the ceiling assembly can be dried in place or requires material removal, and provide a written scope. Read more about our water damage restoration and structural drying services.
