Emergency Sewer Replacement in Longmont, CO
A collapsed sewer line can cause sewage backups into your home. Call (720) 727-9398 for emergency service. We inspect, locate the break and plan repairs fast. Temporary measures may restore flow until replacement. Fast response limits damage.

Sewer Cleanout Installation in Longmont, CO
A cleanout provides easy access for future cleaning and inspection. Many older homes lack an exterior cleanout. We install one during sewer replacement. This saves time and money on future maintenance. It also helps in emergencies.
Open-Trench Sewer Replacement in Longmont, CO
Some lines have severe sagging, wrong slope or are too shallow for trenchless methods. In these cases, open-trench replacement is the best option. We excavate, remove the old pipe and install new PVC with proper bedding. We restore the trench once it passes inspection. This method allows full correction of slope problems.
Sewer Line Repair vs. Full Replacement in Longmont
Deciding between repair and full replacement depends on the extent and nature of the damage. Minor cracks or isolated clogs might be resolved with spot repairs, but widespread corrosion, multiple breaks, or a collapsed pipe often necessitates a full replacement. Our technicians in Longmont will conduct a thorough camera inspection to accurately diagnose the problem and recommend the most cost-effective and long-term solution. We provide clear explanations and transparent pricing for both options.

Trenchless Sewer Replacement Options in Longmont, CO
When appropriate, trenchless sewer replacement offers a less invasive alternative to traditional digging. Methods like pipe bursting or pipe lining allow us to replace or repair your sewer line with minimal excavation, often only requiring two access points. This can save your lawn, driveway, and landscaping from extensive damage, making it a common choice for homeowners in Longmont who want to preserve their property's appearance. We'll assess if your sewer line is a good candidate for this advanced technique.

Frequently Asked Questions About Sewer Replacement in Longmont
Sewer replacement usually costs $4,500 to $12,000 depending on length, depth and method. Trenchless pipe bursting often runs $6,000 to $15,000, while under-slab work can cost more.
After replacement, avoid planting large trees or shrubs near the sewer line's path. Be mindful of what goes down your drains, and avoid flushing grease, wipes, and harsh chemicals. Regular professional inspections, especially if you have older pipes, can also help identify potential issues early.
Yes, sewer line replacement in Longmont, CO almost always requires a plumbing permit from the local municipality. This ensures that the work is performed to code and inspected for safety and proper function. GFR Plumbing handles all necessary permit applications and inspections for your project.
Trenchless reduces digging and surface damage. Traditional replacement is better when slope must be corrected.
For sewer replacement, we mainly use durable and long-lasting materials like PVC (polyvinyl chloride) and ABS (acrylonitrile butadiene styrene) pipes. These materials are resistant to corrosion, tree root intrusion, and chemical damage, offering a much longer lifespan compared to older clay or cast iron pipes commonly found in Longmont homes. We select the best material for your specific property and local conditions.
Trenchless sewer replacement, such as pipe bursting, is a great option for many, but not all, situations in Longmont. It's best used for pipes that are mostly intact but have cracks or minor breaks. If the pipe is completely collapsed, severely misaligned, or made of certain materials like Orangeburg, traditional trenching might be the only viable solution.
Sewer line replacement is a complex and hazardous job that should only be performed by licensed and experienced professionals. It involves excavation, working with potentially contaminated materials, understanding plumbing codes, and operating heavy equipment. Attempting a DIY replacement can lead to serious health risks, code violations, and even more costly damage to your property. It is strongly recommended to hire a professional plumbing company like GFR Plumbing.
Frequent backups, slow drains throughout the house, sewage odors and soggy yard areas are typical signs. Camera inspection confirms the problem.
