An emergency plumber in Thornton deals with the problems that cannot wait: a burst or split pipe, sewage backing up into the house, water you cannot shut off, or a water heater that is leaking or has gone cold in a freeze. In every one of these, the first move is the same. Stop the water at the source, then call so we know what you are seeing.
What an emergency looks like
Active water damage is the line to watch. A pipe that is spraying or steadily leaking, a toilet or drain that keeps backing up no matter what you do, standing water anywhere in the house, a shutoff that will not close, or no hot water when temperatures are below freezing: all of these count. A slow drain, a dripping faucet or a running toilet is annoying but rarely urgent, and those are better scheduled so the diagnosis is not rushed.
What to do right now
Knowing where your shutoffs are matters more in an emergency than almost anything else. Closing the right valve can turn a flooded basement into a puddle.
- Main shutoff: in many Thornton homes this is in the basement or crawl space near the front wall, or it is the curb stop out near the street.
- Water heater: the cold supply valve sits on top of the tank and stops water from feeding a leaking or overflowing unit.
- Toilets and sinks: each fixture usually has its own stop valve underneath, which is the fastest way to isolate a single problem without shutting off the whole house.
- Split pipe: after shutting the main, open a faucet at the lowest point in the house so the pressure and the water in the line can drain out.
- Sewage: stop running water and using drains, and keep people and pets out of the wet area.
If you cannot find a valve safely, do not force it. Stop running water where you can, move belongings out of the wet area, and call when the line is open.
Burst and frozen pipes in a hard freeze
A Front Range cold snap is what usually causes this. Copper and galvanized pipe running through an unheated crawl space, an exterior wall, or an attached garage is the pipe that splits, and a hose bib left connected to a hose is a classic freeze failure. If a pipe has burst, shut the main and expect us to isolate that section rather than repipe the whole house on the spot. If a pipe is frozen but has not split yet, do not use an open flame to thaw it. The repair itself is usually cutting out the split section and replacing it, which is covered in more detail on our water leak repair page. If the line that failed is the one running from the street to the house, see water line repair.
Sewage backing up into your home
Gurgling drains, a toilet that will not flush properly, or sewage smell inside the house point to a blocked or damaged sewer line. In older 80229 neighborhoods this is often root intrusion at a clay joint. Stop running water and using drains anywhere in the house, because more water going down the line usually makes a backup worse, not better. If only one sink, tub or toilet is blocked, that is clogged drain repair. If several fixtures back up at once, the blockage is in the main line, which is drain cleaning, and if the camera shows a broken or bellied pipe, sewer line repair covers the options.
Water heater leaking, or no hot water in a freeze
If the tank itself is leaking, shut the cold supply valve on top of the tank. For an electric heater, turn off its breaker. For gas, set the gas control to off or pilot. A tank that leaks from the shell, not a fitting, is usually a corroded tank, often once the anode rod is spent, and it will not hold a patch. No hot water in a hard freeze is more often a failed thermocouple, a dead element or a frozen line in an unheated space. Our water heater repair page covers what we check.
If you smell gas, stop and get out
This is the one situation where the plumbing itself is not the first concern. Leave the house immediately, do not flip any light switches, and call Xcel Energy or 911 from outside. Once everyone is safely out and the gas company has cleared the area, we can look at any plumbing involved.
What affects the cost
The price of an emergency repair depends on what has failed, how hard it is to reach, how much has to be opened up (a wall, a floor, a stretch of yard), the parts and materials, and whether a permit is needed. We put a written scope and price in front of you to approve before work begins.
When to call
Call (720) 856-5811, Monday to Saturday, 9am to 6pm. Outside those hours the phone is not answered, so shut off the water, limit the damage, and call when the line opens. When you call, tell us what you are seeing, where it is, how long it has been happening, and whether water is still running or has been shut off. For gas, fire or water near live electrical, call 911 first.
Technician insight
The most useful thing a Thornton homeowner can do before an emergency is find the main shutoff and check that it turns. In older 80229 houses the main is often an old gate valve that has not been touched in years and can seize or break when it is finally forced, so it pays to test it gently on a calm day, not in the middle of a burst pipe.
A common call
Say a pipe splits behind the washing machine during a hard freeze and water starts pooling on the floor. You shut off the main, then call and tell us what you are seeing and where. We isolate the section, explain what caused it, often older galvanized pipe in an unheated space, and give you a written scope before doing the repair.
