What happens when you call
Tell us the location of your San Marcos property and a callback number, which rooms show moisture, and how the problem spread. We'll discuss access, availability and assessment, and explain how we'd approach locating the source.
Tracing moisture across multiple rooms
For example, you may notice moisture or staining that appears in more than one room with no obvious shared source. Water can travel along a shared wall, floor cavity, or plumbing run and show up room-to-room, which makes the entry point hard to pin down without mapping.
Our Oceanside-based team uses thermal imaging and moisture meters to map moisture across the affected rooms, identifies the likely path it traveled, and helps narrow the most probable source before any opening of materials is considered. A qualified plumber repairs the leak source; SunCoast detects the moisture and restores the damage across each room it reached.

Locating hidden moisture and possible leak paths
Not every leak is obvious. Water can travel along building materials and appear far from where it enters. SunCoast Restoration uses professional diagnostic equipment — moisture meters, thermal imaging, hygrometers and other tools — to help identify hidden moisture and possible leak paths in San Marcos properties while minimizing unnecessary demolition when possible.
While non-destructive methods can locate many leaks, some situations may still require limited access to building materials to confirm the source. SunCoast focuses on identifying the most likely location of the moisture first so any necessary access is as targeted as possible. A qualified plumber should repair the leak source; we help detect the moisture and restore the resulting damage.
Help with documentation
SunCoast helps document the damage and the restoration work so the information your insurer may request is organized and clear. Your insurer determines coverage under your policy; SunCoast cannot guarantee payment or claim approval.
