How to Keep Your Pipes From Freezing This Colorado Winter
Colorado has a way of giving us sunshine at lunchtime and frozen windshields by bedtime. That fast temperature swing is tough on plumbing, especially when pipes sit in crawl spaces, garages, attics, and exterior walls. As an emergency plumber westminster co homeowners call during winter cold snaps, we at To the T Plumbing, Heating & Air have seen how quickly a frozen pipe can turn into a burst pipe.
The good news is that a little prep now can save a lot of stress later. Here is what we recommend before the first real freeze hits the Front Range.
Why Colorado homes are at risk for frozen pipes
Frozen pipes are not just a “mountain cabin” problem. They happen all over the Denver metro and Northern Colorado.
Here is why our homes are vulnerable:
Overnight temperatures can drop fast after a sunny day.
Pipes often run through unheated areas like crawl spaces, garages, attics, and unfinished basements.
Exterior wall plumbing can get cold even when the room feels comfortable.
Outdoor spigots and sprinkler lines can hold water if they are not drained.
Wind can push cold air through small gaps around foundations, vents, and utility penetrations.
When water freezes, it expands. That expansion puts pressure inside the pipe. Sometimes the pipe does not burst right where the ice forms. It may split several feet away where pressure builds. That is one reason frozen pipe problems can be tricky.
How to keep your pipes from freezing before the cold hits
A good winter plumbing checklist does not have to be complicated. These are the steps we would take at our own homes.
Disconnect garden hoses
This is one of the easiest winter jobs, and one of the most commonly missed.
Remove all garden hoses from outdoor spigots before freezing weather arrives. A hose can trap water at the faucet, which lets ice push back into the spigot and the pipe behind it.
Once the hose is off, drain it and store it somewhere dry. Your future springtime self will appreciate it too.
Shut off and drain outdoor spigots
If your home has interior shutoff valves for outdoor faucets, turn them off. Then open the outside spigot to let remaining water drain out.
Some homes have frost-free hose bibs, which are designed to reduce freezing risk. They still need the hose disconnected to work properly. If you are not sure what type you have, we can take a look during a pre-winter plumbing inspection.
Make sure sprinklers are blown out
Sprinkler systems need to be winterized before hard freezes settle in. If water is left in the irrigation lines, valves, or backflow assembly, freezing can crack parts and create leaks underground or near the foundation.
If your sprinkler blowout is already done, great. If not, do not wait until every appointment in town is booked. Colorado weather does not always send a polite calendar invite before it drops below freezing.
Insulate exposed pipes
Pipes in unheated areas need extra help. Foam pipe insulation is widely available and can be installed around exposed water lines in places like:
Crawl spaces
Garages
Attics
Unfinished basements
Utility rooms
Exterior wall areas where pipes are visible
Focus on both hot and cold water lines. Hot water pipes can freeze too, especially if they are not being used for long stretches.
For areas with major drafts, insulation alone may not solve the whole problem. Sealing cold air leaks can make a big difference.
What to do on very cold nights
When the forecast calls for a deep freeze, a few small moves can help keep water moving and warm air circulating.
Open cabinet doors under sinks
If a sink sits on an exterior wall, open the cabinet doors underneath it during very cold nights. This lets warm room air reach the pipes.
This is especially helpful in kitchens, bathrooms, and laundry rooms where plumbing is tucked against an outside wall.
If you have pets or small kids, move cleaning products out of the cabinet first. Safety still gets the front seat.
Keep the thermostat steady when traveling
If you leave town, do not turn the heat way down to save a few dollars. Keep the thermostat set at a steady, safe temperature so the house does not get cold enough for pipes to freeze.
If your home has a smart thermostat, check that it is connected and working before you leave. If your furnace has been acting up, schedule service before travel. We are licensed plumbing and HVAC pros, and as a Lennox dealer, we know how much reliable heat matters when the plumbing is counting on it.
Know where your main water shutoff is
Every homeowner should know where the main water shutoff valve is. If a pipe bursts, shutting off the water quickly can limit damage.
Common locations include:
A basement wall facing the street
A crawl space
A mechanical room
Near the water heater
Inside a utility closet
Make sure the valve turns. If it is stuck, leaking, or hard to reach, have it repaired before it becomes an emergency.
Warning signs of a frozen pipe
Frozen pipes are not always obvious at first. Watch for these signs during a cold snap:
No water, or only a trickle, from one faucet
Frost or ice on a visible pipe
Bulging or cracked pipe sections
Gurgling sounds from drains or fixtures
Odd smells coming from drains
That odd smell can happen when a frozen section blocks normal drainage or venting. If something seems off, do not ignore it.
What to do if you think a pipe is frozen
Start by turning off water to that area if you can. If you are not sure where the shutoff is, use the main shutoff.
Open the faucet connected to the frozen line. This gives melting water and pressure somewhere to go.
You can try gentle warmth on an exposed frozen pipe with:
A hair dryer
Warm towels
A space heater placed safely away from combustibles
Never use an open flame to thaw a pipe. That means no torch, no lighter, no propane heater pointed at the pipe. Fire risk is real, and too much heat can damage plumbing fast.
If you cannot reach the frozen section, if the pipe is behind a wall, or if you see leaking, call us.
When to call an emergency plumber Westminster CO can count on
A burst pipe is an emergency because water damage spreads fast. Once a pipe splits, water can soak drywall, flooring, cabinets, insulation, and framing. It can also run into lower levels of the home before anyone notices.
