Quick answer. Protect people first. Shut off the water if the leak is from a supply line, stop using the fixture if it is a drain, and cover exterior leak points if weather allows. Take photos, move items away from the wall, and start safe airflow. Open the wall low and small to release trapped water only when power is safe. For free help call +1 604 800 3900.

Early Signs Of A Wall Leak
- Soft drywall, bubbling paint, or hairline cracks near baseboards
- Musty smell in one room or closet that does not clear
- Warm or cool spots on the wall compared to nearby areas
- Flooring cupping or swollen trim under the suspected wall
- Water sounds when no fixtures are running
Safety First
- Stay clear of outlets and switches on the wet wall
- If water is near power, do not touch the wall. Wait for a professional
- Do not cut or drill where electrical lines or gas pipes may run
- Use gloves and eye protection when removing wet materials
Find And Stop The Source
Supply line leak
- Close the nearest shutoff valve. If none, close the main water valve
- Open a lower faucet to relieve pressure
Drain or fixture leak
- Stop using the sink tub or appliance that drains into that wall
- Place a pan or bucket if water is dripping at a visible point
Rain or exterior leak
- Cover exterior entry points with a tarp if weather and access are safe
- Move water away from the foundation with downspout extensions
Step By Step Emergency Actions
- Protect the area. Move furniture and rugs, place towels at the base of the wall
- Document. Take wide and close photos and a short video of the wall and suspected source
- Start airflow. Open inside doors and use a fan to move air across the wall surface, not into open cavities
- Control humidity. Run a dehumidifier in the room and empty it often
- Monitor. Mark the highest wet line with painter tape to see if it spreads
Small leaks can dry with quick control. Ongoing leaks or wet insulation need a targeted opening and professional drying.
When To Open The Wall
- Drywall is soft or buckled and stays wet after a full day of airflow
- You see staining grow or smell is stronger behind baseboards
- Water is trapped inside the cavity and seeping out at the base
Safe approach. Turn off power to that circuit if outlets are on the wall. Remove the baseboard. Cut a small strip of drywall near the floor to release water and view the cavity. Avoid cutting higher until utilities are located. Photograph what you see.
Drying The Wall The Right Way
- Extract standing water with a wet vacuum
- Use air movers across the opening to move air through the cavity
- Run dehumidifiers to control room humidity
- Remove wet insulation that will not dry in place
- Check daily until materials reach dry targets

FAQs
Should I cut the wall open right away
Only after power is safe and the source is controlled. Start with a small opening near the base after removing the trim. Photograph everything.
Can fans and a dehumidifier dry the wall without opening it
Sometimes for light wetting on the surface. If insulation is wet or the smell grows you need a targeted opening and controlled drying.
How soon can mold start
Growth can begin within one to two days on wet materials. Quick action keeps the scope small.
Will insurance cover this
