DetailsBefore It Gets Worse
Six signs you should call a plumber tonight, not next month.
Plumbing problems rarely announce themselves with a flood. These are the quiet warnings worth taking seriously.
A stain spreading on a ceiling or wall
Usually a hidden leak in a pipe or fitting — and the damage you can see is rarely all of it.
Leak Detection & Repair →Every drain is slow, or you hear gurgling
One slow sink is a clog. All of them at once points to the main sewer line — before it backs up.
Drain Cleaning →Lukewarm showers, rumbling, or rusty hot water
Classic signs a water heater is struggling. Caught early, it may be a repair instead of a replacement.
Water Heater Repair & Replacement →Water pressure that suddenly dropped
Often a corroded or failing pipe losing water somewhere you can’t see it.
Pipe Repair & Repiping →A shut-off valve that’s stuck or weeping
A valve that won’t turn is the one thing you need working in an emergency. Fix it before you need it.
Valve Repair & Replacement →A toilet that runs, a drip that won’t stop
Small, constant, and wasteful — and usually a quick, inexpensive fix when handled properly.
Fixture Installation & Repair →Not sure if it's urgent? Call and describe what you're seeing — we'll tell you honestly whether it can wait.

“Woke up on New Year's Day to a pipe leak over our garage ceiling. What a way to start the year! Finding someone on short notice was a bit of a challenge! A1 Colorado Plumbing was available to stop by and repair the issue. Harold found and addressed the issue within an hour of arriving and also provided assistance mitigating water damage and mold to the ceiling! Very personable and great to work with.”
“I woke up to a flooded basement at 3:30 a.m. about a week ago. Thanks to Google I got ahold of Harold at A1 Colorado Plumbing. He was on the job within thirty minutes. Took him about half that time to diagnose the problem — a broken sprinkler valve. Took him about an hour to replace that. I asked him to recommend someone to help with all the water. To my surprise he said he would take care of that as well.”
“Harold is professional and efficient. I would highly recommend him. He diagnosed and successfully completed a difficult plumbing issue in my home.”
“Drove up on a Sunday night. We had no water with a valve break to our hose, and had to shut it off. He was clear, explained things well, and did a fine job, and got our water back in short order. Pricing was very reasonable.”
“Dean did numerous jobs on plumbing at our house. He was very knowledgeable, personable and a hard worker. Would highly recommend him.”
