Where pipes freeze
Freezing almost never happens in the middle of a warm house. It happens at the edges: exterior walls, rim joists, floors over garages, crawl spaces, and anywhere a draft gets in. In Milton the usual suspects are sinks set against outer walls, bathrooms perched above garages, and hose bib lines running through the rim joist.
Fall jobs, in order
- Disconnect hoses and close the indoor valve feeding every hose bib, then let the outside spout drain open. Our outdoor faucet pamphlet has the details.
- Seal drafts around pipes where they pass through the rim joist or exterior walls. Spray foam and caulk do the job.
- Sleeve exposed pipes in cold spaces with foam, especially near garage walls and crawl space vents.
- Check the garage. If water lines run through it, keep the big door closed in cold weather.
- Find your main valve and make sure it turns. If a pipe bursts, you will want it closed fast.
Cold snap routine: open cupboard doors under sinks on outside walls, keep the heat steady at night, and let a tap on a vulnerable line drip slightly.
If you are going away
Never turn the heat off in winter. Set the thermostat to a moderate temperature, ask someone to check the house, and consider closing the main valve while you are gone. Our travel checklist covers the rest.
Signs a pipe has frozen
- A tap gives a trickle or nothing while others run normally.
- Frost on a visible pipe.
- A toilet that will not refill.
Crack open the dead tap and add gentle warmth, never a flame. If the ice cannot be located, or any pipe shows a bulge, close the main and ring us. Our frozen pipe thawing service covers the rest.
Stopping repeat freezes
When one pipe freezes every winter, the cure is permanent: reroute it inside the heated space, insulate and seal the wall cavity properly, or add self-regulating heat cable approved for the purpose. A tankless water heater on an outside wall also needs its freeze protection kept powered.
Questions we get asked
How warm should the house stay in January?
Keep a steady, moderate setting day and night. Big night-time setbacks invite trouble on cold walls.
Does dripping a tap really help?
On vulnerable lines during extreme cold, a slow drip keeps water moving and relieves pressure.
Is heat tape safe?
Use self-regulating cable approved for pipes, installed to the maker’s instructions.
