A Year-Round Plumbing Checklist for Longmont Homes
Longmont sits along the St. Vrain Creek corridor at the base of the Front Range, where a blend of century-old homes near Old Town and newer, design-forward construction in neighborhoods like Prospect New Town means plumbing systems of very different ages all face the same seasonal swings. Southwest Longmont’s established ranch homes add another layer, since many still run on original mid-century plumbing that hasn’t been updated since the neighborhood was first built. Use this seasonal checklist to catch small problems — a slow drain, a hairline slab crack, a dripping outdoor spigot — before they turn into a same-day emergency call. If you’re already dealing with a leak, skip ahead and call for 24/7 emergency service; if you’re getting ahead of the season, work through the list below room by room.
Spring: Watch for Snowmelt and Freeze Damage
As mountain snowmelt swells the St. Vrain Creek and spring rain soaks into the ground, Longmont homes near the creek corridor can see added pressure on foundations and drainage systems.
- Check the water meter with all fixtures off — a moving dial can mean a hidden leak from winter freeze damage.
- Inspect exposed pipes in crawl spaces and basements for hairline cracks left by winter’s freeze-thaw cycles.
- Test sump pumps before spring runoff, especially in homes near the St. Vrain Greenway.
- Look for new cracks in slab flooring or uneven doors, early signs of clay-soil movement affecting the foundation.
Summer: Manage Heat, Hail, and Heavier Use
Longmont’s summer hailstorms and monsoon downpours can overwhelm gutters, while irrigation and higher water use strain plumbing fixtures across the city.
- Clear gutters and downspouts before monsoon season to keep roof runoff away from the foundation.
- Check outdoor spigots and irrigation lines for leaks now that they’re back in regular use.
- Flush the water heater to clear mineral sediment before summer’s higher hot-water demand.
- Inspect washing machine hoses for wear, especially in Old Town’s older homes with original plumbing.
Fall: Prepare Before the First Hard Freeze
Longmont can see its first hard freeze as early as September, so fall is the last reliable window to winterize before pipes are at risk.
- Disconnect and drain garden hoses, and shut off exterior spigots before the first hard freeze.
- Insulate exposed pipes in unheated crawl spaces and garages, especially in Old Town’s original housing stock.
- Have your water heater inspected if it’s approaching 8 to 12 years old.
- Clear leaves and debris from drains and gutters ahead of the first winter storms.
Winter: Prevent Frozen and Burst Pipes
Longmont winters bring sharp overnight drops, and homes with exterior-wall plumbing or unheated additions are most at risk for a burst pipe.
- Keep cabinet doors open under sinks on exterior walls during cold snaps so warm air can reach the pipes.
- Let faucets drip slightly during extreme cold to relieve pressure inside the line.
- Know where your main shutoff valve is — if a pipe does burst, turning it off quickly limits damage.
- Watch for sudden drops in water pressure, which can signal a partially frozen line before a full burst.

Frequently Asked Questions
Is there an emergency plumber in Longmont available right now?
Yes. Emergency Plumbing Squad dispatches licensed, insured emergency plumbers across Longmont 24/7, including nights, weekends, and holidays.
How often should I flush my water heater in Longmont?
Manufacturers generally recommend flushing a tank-style water heater about once every year to clear mineral sediment buildup, which supports its typical 8-to-12-year lifespan.
Why do Longmont homes near Old Town get more plumbing issues?
Many Old Town homes were built decades ago on original galvanized or cast-iron plumbing, and aging pipe is more prone to corrosion, hidden leaks, and reduced water flow than newer copper or PEX lines installed in recent renovations.
What should I do if I find a burst pipe in winter?
Shut off water at the main shutoff valve immediately, then call for 24/7 emergency service right away — see the number above for dispatch.
