Keeping Pipes from Freezing for Colorado Homes
Cold Weather, Costly Mistakes: Why Frozen Pipes Are a Big Deal in Colorado
When winter sweeps across Coloradoโs Front Range, homeowners in Longmont, Boulder, and the Denver area face a familiar risk โ frozen pipes. Sub-zero nights, powerful winds, and large day-to-night temperature swings make plumbing systems especially vulnerable.
When water inside a pipe freezes, it expands, creating intense pressure that can burst copper or PEX lines. Even a tiny crack can leak hundreds of gallons of water per day, flooding basements and damaging walls, insulation, and flooring.
The good news? Keeping pipes from freezing isnโt complicated. Itโs about knowing where your plumbing is most exposed and preparing before the deep freeze hits.
How Freezing Damages Your Plumbing
Pipes in unheated or poorly insulated areasโlike crawl spaces, basements, attics, and garagesโface the greatest danger. Freezing often begins as a subtle trickle at a faucet or a small frost patch on an exposed line. Once ice blocks the pipe completely, pressure quickly builds behind it, bursting joints or fittings.
The key to preventing expensive repairs is simple: stop ice from forming in the first place.
Expert Tips for Keeping Pipes from Freezing
1. Insulate Exposed Pipes
Add foam sleeves or fiberglass insulation around pipes in crawl spaces, basements, and along exterior walls. For high-risk areas, install UL-listed heat tape or electric heat cables for extra protection.
Professional pipe insulation can make the difference between a safe winter and a burst-pipe emergency. Ask Blue Valley for pipe insulation tips specific to Coloradoโs cold-weather climate.
2. Maintain Consistent Indoor Heat
Keep your thermostat steady, ideally no lower than 55ยฐF, even if youโre away. Consistent warmth prevents cold air from settling inside walls and cabinets.
Our Longmont heating team recommends scheduling a pre-winter furnace tune-up, since a properly maintained HVAC system not only ensures comfort but also protects your plumbing from freezing.
3. Keep Water Flowing
During severe cold snapsโespecially when overnight lows hit the teens or belowโlet faucets drip slightly. Moving water is far less likely to freeze, and the steady trickle relieves pressure if ice begins to form inside the pipe.
4. Seal Leaks and Drafts
Cold air enters through foundation cracks, attic vents, and gaps near plumbing penetrations. Use caulk, spray foam, or insulation wrap to seal openings around pipes. This small step can raise nearby temperatures several degreesโoften enough to prevent freezing altogether.
5. Disconnect and Drain Outdoor Plumbing
Before the first freeze, detach garden hoses, shut off outdoor spigots, and drain sprinkler lines.
If you have an underground irrigation system, schedule professional winterization to remove trapped water. Frozen sprinkler pipes can burst underground and leak unnoticed until spring.
6. Install Preventive Technology
For the ultimate protection, consider smart leak sensors or temperature monitors that alert you if pipes approach freezing.
Blue Valley also installs frost-proof faucets and automatic pipe heating systems that activate when temperatures drop below a set threshold. These upgrades offer reliable, hands-off preventionโperfect for frequent travelers or rental properties.
