"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."

"Precision installed my water heater two years ago. When I had my furnace serviced, the technician checked the pressure on the water heater and it was very high, a component had failed. A plumber from Precision came out and replaced the defective part since it was under warranty. He suspected that a water pressure regulator may have to be installed but when he checked the water pressure coming into the house, it was in the acceptable range. He could have just as easily told me I needed this and it would have cost me $600 but Jacob was an honest man. I am so impressed with his integrity. I will use them again in the future for sure. The replacement of the defective part didn't cost me anything. Thank you Precision for being an honest company."

"This all began with Zach checking our ancient Warm Morning wall heater while he was here to do a yearly maintenance check on our Rinnai water heater. We were startled when he got a reading of 45 on his carbon monoxide meter close to the heater vent - he suggested we replace the heater right away as this was not safe at all. He was gracious enough to find us a new wall heater immediately, and Brady and Dylan came back the very next day to remove the old heater and put in the new one. They worked hard all day and did a good job. Brady and Zach came back five days later to cut a vent into our bedroom and also went the extra mile to put in extra rubber gaskets and padding to relieve some rattling and mitigate as much of the noise as possible. We are relieved to be coughing less, breathing better, and to have a good heater that works well for our needs. These guys were kind, professional, and very careful about keeping our home clean, especially when removing our old heater that was full of soot - they did a great job and we are pleased with the results. Docked half a star only due to some confusion with the invoice and not clearly giving a breakdown of costs for the heater itself and for labor and installation, but overall, a job well done! Thank you all!"

"Excellent, very professional job. Tyler repaired our bathtub fixtures and replaced the leaking main water-supply valve, as well as the defective water-pressure regulator. He did all that on time and at a reasonable price. Highly recommended."

"Our hot water heater went out recently. It was 12 years old, so we knew we needed a new one. It took quite a bit of research to find a reputable company that didn’t have exorbitant prices. Other businesses told us things like: we needed all new pipes. (We didn’t.) A new hot water heater would be $3,000 to $5,000 plus labor on the of that. ( way overpriced), etc. Finally, we found an excellent smaller local company. We went with Pure Water Services in Loveland. They’re honest, reasonably priced, and absolute pros. They were able to get us scheduled for a new hot water heater within days . Their master plumber Patrick was courteous, extremely knowledgeable, and very thorough. Patrick is an impressive and experienced plumber. Alexander keeps in touch daily with every step of your project repair. I was impressed with how kind, and professional he is to customers. We are so thankful to have hot water again. They stand by their work. My husband and I highly recommend them!"

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.
