"It's the night before I need to leave town for a work trip in the middle of the pandemic. I hear some noise downstairs that doesn't sound quite like traffic...a pipe in my garage cracked in three different places and started spraying water all over my garage. I scrambled to find and call a plumber. James picked up right away and was at my house within two hours. He had all the tools and replacement materials needed to complete the job efficiently. In less than an hour, the old, cracked pipe was gone, the new material was installed and I was able to run water throughout my house with no leaks. Not sure what I would have done without his help (especially on a day when pipes were bursting all over the area). Would recommend James' services far and wide."

"As I remember, I was told there was more work done to get the garbage disposal installed. Did quite a lot of extra work that I'd forgotten. Guy that came out to do the work, from my memory, the installation was good. Though it was a little pricey, but in hindsight, it was probably a good deal. "

"Where do I start?! We hired Michael to fix our water heater, he responded quickly & was able to get us in later in the evening. He called to let us know when he was on his way & when he came he wasted no time. He explained what was wrong with our water heater & gave us a reasonable quote. We needed a part that was half way across town during traffic time so to make sure we got the part we needed he rushed down to grab it before the placed closed & came back & was able to fix it that night (thanks goodness he did because it was snowing & no one wants to use cold water when it snows). If you want a professional, affordable, & reliable plumbing company, Michael is your guy! We will definitely be using him for any future needs!"

FAQs for water main install, replace or repair projects in Boulder, CO

If you notice puddles or standing water in your yard, a sudden drop in water pressure, cracks forming in your foundation, frequent clogs in your plumbing fixtures, or water that looks or smells unusual, you might have a leak in your main water line. These signs mean it's time to call a professional to evaluate the issue and prevent further damage.

A professional water main inspection is a comprehensive evaluation performed by a licensed plumber who checks every section of your plumbing system. The inspection costs $165 and uses advanced diagnostic techniques to identify hidden leaks or wear. This service clarifies the exact condition of your water main, enabling precise repairs that prevent future damage and ensure the overall health of your plumbing system.

Protect your water main by scheduling a cleaning and inspection every two to five years. The average cost of a sewer line cleaning is $400. It’s also important to never dig in your yard without first calling the dig line (811) to ensure you don't accidentally hit the water or sewer lines. Watch for soil erosion, low water pressure, or wet spots in your yard, and take immediate action if you suspect a leak. Remember, the longer you leave it, the worse the problem gets and the more costly it is to fix.

When properly maintained, your water main is engineered to remain functional for 50 years or longer. A durable water service in excellent condition should consistently perform without major issues for half a century. In contrast, metal pipes exposed to acidic soil corrode faster, whereas modern plastic pipes resist corrosion and function for decades beyond metal alternatives. Regular maintenance and inspections are essential for confirming your system’s longevity.

No, homeowners insurance does not cover the cost to repair a water main. Insurers fund only sudden, unforeseen events like a burst pipe and exclude gradual issues or normal wear and tear. Damage resulting from leaks, such as mold remediation or property claims, is not covered. It is essential to contact your insurance provider immediately to confirm your policy’s details and any potential adjustments needed.
