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.

Frequently Asked Questions
Do you really take calls at night and on holidays?
Yes — A1 Colorado Plumbing is available 24 hours a day, 7 days a week, holidays included. If you have a plumbing emergency, call (303) 521-5844 any time and someone will answer.
How quickly can you get to my home in Littleton?
We respond to emergency calls as fast as we can — many customers in the Littleton area have had us on-site within the hour. Response time depends on your location and current call volume, but speed is always the priority.
Will you help with water damage cleanup, or just fix the pipe?
We go beyond the repair when we can. On some emergency calls we've assisted directly with water damage mitigation rather than leaving the homeowner to deal with it alone. Ask us what's possible when you call.
What kinds of plumbing jobs do you handle?
We cover a wide range: emergency repairs, burst pipes, drain cleaning, water heater repair and replacement, leak detection, valve repair, pipe replacement, and fixture installation. If you're not sure whether your situation fits, just call and describe what's happening.
How does pricing work — will I know the cost before you start?
We explain what's wrong and what it will take to fix it before we proceed. Our customers consistently note that our pricing is fair and transparent — we're not here to upsell you on work you don't need.
Do you serve areas outside of Littleton?
Our primary area is Littleton and surrounding Front Range communities. Call (303) 521-5844 and we can quickly confirm whether we cover your location.
