How to Prevent Frozen Pipes Through an Anchorage Winter

Exterior spigots are the single most common failure point. Disconnect every hose, close the interior shut-off if the bib has one, then open the spigot to drain the remaining water. A hose left attached traps water in the bib and splits it on the first hard night.

Insulation slows heat loss; it does not stop moving cold air. If a crawlspace vent, rim joist gap or garage penetration is blowing cold air directly across a pipe, sealing that path matters more than the pipe wrap. Do the air sealing first, then insulate the pipe.

Before winter, find your main shut-off valve and confirm it actually closes. Seized valves are extremely common, and discovering yours does not work while water is running through a ceiling is the worst possible time.

If it will not close smoothly, replacing it is a small job now and an expensive one later.

Open the affected faucet so melt water has somewhere to go, then apply gentle heat working from the fixture back toward the blockage. Never use an open flame. Watch for a split as pressure returns, and keep the shut-off within reach.

If you lose water to a whole section of the house, or the pipe is inside a wall, call us. Thawing a hidden line without damaging it takes the right approach.
