How to Prevent Frozen Pipes in Estonian Winter

Frozen pipes are one of the most common winter emergencies in Tallinn and Harjumaa. When water freezes inside a pipe, it expands and can crack or burst the pipe entirely — leading to serious water damage. Here is what you can do to prevent it.

1. Insulate exposed pipes

Any pipes running through unheated spaces — attics, basements, garages, or exterior walls — are at risk. Wrap them with foam pipe insulation or heat tape before temperatures drop. This is cheap insurance against a very expensive repair.

2. Keep the heating on, even when away

If you leave for the weekend or holiday, never turn your heating completely off. Keep it at a minimum of 12–15°C throughout the home, including rooms you don't use. Cold rooms with exterior walls are exactly where pipes freeze first.

3. Let a trickle of water run overnight

On nights with extreme cold (below -15°C), let a cold-water tap on an exterior wall drip slowly. Moving water is much harder to freeze than still water.

Already frozen? Call Ajsan immediately

If you turn on a tap and nothing comes out, or water trickles slowly, you likely have a frozen pipe. Do not try to thaw it with an open flame — this can crack the pipe or start a fire.
