How Can I Find a Water Leak Inside a Wall or Ceiling?

You can spot a hidden wall or ceiling leak by watching for damp stains, bubbling paint, musty odors, and listening for dripping. If you suspect a leak in a Seattle or Everett home, act fast to limit damage. Apollo can locate leaks with video/camera inspection, hydrostatic testing, low‑pressure air tests, and pneumatic test balls, then repair with minimal opening. A licensed tech will present options and an Upfront No Surprise Price before work begins.

Quick checks:

• Turn off fixtures; watch the water meter for movement.
• Shut individual fixture valves to isolate.
• Inspect above the stain and under sinks.
• Avoid opening walls near wiring; call a pro.
