"I highly recommend Mountain Valley Plumbing & Heating! I had a furnace installed six years ago by a different company, Steele Bros Heating, Inc. located in Denver. My furnace is a high-efficiency condensing furnace, yet they never installed the condensate drain line— a huge mistake — it's not only dangerous, but totally embarrassing to overlook such an important part of the installation! I had Mountain Valley Plumbing & Heating come out for a furnace tune up, and their technician, Scott realized the issue. The motor in my furnace was underwater due to the lack of the drain and my furnace wouldn't turn on. I called Steele Bros Heating to fix the problem, and they placed the blame on me, saying I should have had the furnace inspected and that because I didn't have them out once a year for maintenance, they would also void my warranty. I immediately called the City of Boulder inspectors to figure out what to do. They were appalled that a HVAC company wouldn't take responsibility for su"

Every day we are invited into our customer’s homes. Into their safe place and sanctuary. Quite often this is in the midst of a concern or issue that needs to be fixed! With an extensive background that spans well beyond just the trades, we love to be different. In addition to decades of industry experience, we bring some secret sauce - we love to take all the time needed to help, to make sure you are comfortable, and to provide amazing solutions. Come BEHOLD the difference!

"Highly recommended and I will be calling next time I need help. My heater wasn't heating so I called around. Dylan was able to come straight over, less than 2 hours after I called the house was warm. Luckily it was a simple fix, no parts needed (a spider had built it's web in there), so the whole repair was covered under the $89 service fee. Dylan was respectful of me and of my home. AND he told me they work on swamp coolers, which is sort of hard to find these days."

FAQs for sewer main install, replace or repair projects in Longmont, CO

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
