The frost advisory that hit the San Luis Valley this week is a good reminder: in Alamosa, the first hard freeze usually shows up while most people still have the hose hooked to the spigot and the swamp cooler uncovered. By January, nights at 7,500 feet routinely drop well below zero, and that is when pipes split. Here is what we tell our own neighbors to do in October, while it is still easy.
Why Alamosa pipes freeze more than you'd expect
The valley floor is high, dry, and clear. Clear skies mean the heat leaves fast at night, and daily swings of 40 degrees are normal. Older homes in Alamosa and the surrounding farm country often have plumbing in crawl spaces, uninsulated exterior walls, or a pipe run along a north-facing foundation. Those are the spots that fail first.
The October checklist
-
Disconnect hoses and shut off exterior spigots. A hose left attached traps water in the spigot, and the freeze splits the pipe inside the wall where you can't see it. You find out in spring when you turn it on and water pours into the wall cavity.
-
Drain or cover the swamp cooler. Shut off the water supply line, drain the pan, and cover the unit.
-
Insulate pipes in crawl spaces and garages. Foam sleeves cost a few dollars per length and are the best money you'll spend this year.
-
Seal air leaks near pipes. A gap around a pipe penetration pulls in subzero air. Caulk or foam it.
-
Know where your main shutoff is and make sure every adult in the house can find it and turn it. Test it once. A stuck valve during an emergency is a bad time to find out.
-
Set a vacation plan. If you're leaving for more than a couple of days, keep the heat at 55 degrees or higher, and open cabinet doors under sinks on exterior walls.
When it's already frozen
If a faucet runs a trickle or nothing at all on a cold morning, you probably have ice in the line. Open the faucet, then warm the pipe slowly with a hair dryer or warm towels, starting nearest the faucet. Never use a torch or open flame. If you see any bulge, crack, or dripping, shut off the main right away.
If a pipe has already burst, shut off the water, kill power to any wet area if it's safe to do so, and call us at (719) 676-2456. Standing water in a wall or under flooring needs to be dried quickly. Our guide on what to do in the first hours of a flood covers the basics that apply to burst pipes as well.
What a burst pipe actually costs
The pipe itself is usually a cheap repair. The damage is what comes after: wet drywall, insulation holding moisture, flooring that cups, and mold that can begin growing within a couple of days if things stay damp. A small leak that runs overnight can be a big job; one that is caught within an hour might only need fans and a dehumidifier.
How we dry a structure
We're IICRC certified, and the process is the same whether it's a farmhouse near Alamosa or a rental downtown. We find the source, extract standing water, take moisture readings in the walls and floors, and set air movers and dehumidifiers. We check readings daily and only pull equipment when the materials are actually dry, not when they merely feel dry. You can read more about our approach on our water damage restoration page.
Insurance notes
Most homeowner policies cover sudden and accidental pipe bursts, but not damage from long-term neglect or a leak that went unnoticed for months. Photograph everything before cleanup, keep receipts for emergency repairs, and call your insurer early. We can provide documentation of moisture readings and drying logs.
Heating and fire safety in the same cold snap
Cold weather also brings space heaters and wood stoves. If you rely on either, read our piece on chimney and wood stove fire prevention before the first fire of the season.
