Immediately shut off your main water valve and call our 24/7 emergency line at (360) 734-6440. Quick action can prevent thousands of dollars in water damage.

To prevent sediment buildup and extend the life of your unit, we recommend a professional water heater flush once a year. This is especially important in areas of Whatcom County with harder water.

• Insulate Exposed Pipes: Focus on pipes in unheated areas like crawl spaces, attics, and garages using foam pipe insulation.
• Drip the Faucets: During extreme cold, let a very thin trickle of water (both hot and cold) run from faucets served by exposed pipes. This keeps water moving and relieves pressure.
• Open Cabinet Doors: Keep kitchen and bathroom cabinet doors open to allow warmer air from the house to circulate around the plumbing.
• Disconnect Outdoor Hoses: Remove, drain, and store garden hoses. Use faucet covers on outdoor spigots.
• Seal Air Leaks: Use caulk or insulation to seal gaps where cold air might enter near piping, such as around dryer vents or electrical wiring.
• Maintain Heat: If you are traveling, keep your thermostat set no lower than 55°F to ensure the interior of the home stays warm enough to protect the plumbing.
