Sewer Pipe Replacement Options in Longmont, CO
When repairs are no longer sufficient due to extensive damage, age or material failure, sewer pipe replacement becomes necessary. We offer various replacement options, including traditional trenching and modern trenchless technologies like pipe bursting or pipe lining. Our experts will assess your situation and recommend the most cost-effective and least disruptive solution for your Colorado property, ensuring a long-lasting new sewer line.

Pipe Burst & Collapse Repair in Longmont, CO
A burst or collapsed sewer pipe can lead to serious damage and unsanitary conditions. These issues can result from shifting soil, corrosion of old cast iron or clay pipes, or heavy vehicle traffic above the line. GFR Plumbing offers emergency repair services to quickly address these critical failures. We precisely locate the damaged section and provide durable repair or replacement options, often using trenchless methods where appropriate to limit disruption.
Commercial Sewer Repair in Longmont
Beyond residential services, GFR Plumbing also provides robust commercial sewer repair for businesses and properties in Longmont. We understand the demands and higher usage rates of commercial plumbing systems. Our team is skilled in addressing larger diameter pipes, more complex layouts and stricter code requirements, so your business operations continue smoothly with minimal downtime. We prioritize efficient and durable solutions for commercial clients.
Bellied Sewer Line Correction in Longmont, CO
A belly is a low spot where the pipe has sagged and holds standing water and solids. Bellies usually form where the original bedding washed out or where the soil settled after heavy rain. Basements are common in Colorado, and shifting soil can crack floor drains, sewer lines, and basement walls over time. We confirm the depth of standing water on camera, then re-bed and re-grade that section to restore proper fall. Correct slope is typically a quarter inch per foot for a typical residential line.
Orangeburg and Cast Iron Sewer Replacement in Longmont
Some older homes still have Orangeburg pipe, a tar-paper material that flattens and blisters over time. Cast iron from the same era corrodes from the inside and scales up until little flow remains. When a camera shows widespread failure, patching is a waste of money. We replace the line in sections or end to end with PVC, and we can usually use trenchless methods to avoid tearing up the whole yard.
Sewer Vent Pipe Repair in Longmont, CO
While often overlooked, the sewer vent pipe is crucial for proper drainage and preventing sewer gas buildup. Issues with vent pipes, such as blockages from animal nests or damage from storms, can lead to slow drains, gurgling noises and foul odors. GFR Plumbing diagnoses and repairs vent pipe problems, making sure your entire drainage system works correctly and safely and protecting good indoor air quality.
Sewer Pipe Relining in Longmont, CO
Sewer pipe relining is a trenchless repair method where a new, durable pipe is created within the existing damaged one. A flexible, epoxy-impregnated liner is inserted into the old pipe and inflated, curing in place to form a seamless, strong and corrosion-resistant new pipe. This method is well suited for addressing cracks, minor breaks and root intrusion without extensive digging. It extends the life of your sewer system and is an excellent option for preserving landscapes in Longmont.

Sewer Line Hydro-Jetting in Longmont
Hydro-jetting is a powerful cleaning method that uses high-pressure water streams to clear stubborn blockages, grease buildup and even tree roots from sewer lines. It's much more effective than snaking for thorough cleaning and stopping recurring clogs. This service is particularly helpful for restaurants and commercial properties in Longmont dealing with heavy grease accumulation, as well as homes with persistent drain issues.

Frequently Asked Questions About Sewer Repair in Longmont
The cost of sewer repair in Longmont, CO can vary a lot, typically ranging from $500 for minor spot repairs to $3,000 for extensive trenchless work, and up to $10,000 or more for full trench-based sewer line replacement. Factors like the extent of damage, type of repair, pipe material, depth and accessibility all affect the final price. We provide a detailed estimate after a thorough inspection.
GFR Plumbing stands behind our work with solid warranties on parts and labor for sewer repair services. The warranty period can vary based on the type of repair and materials used, but we always make sure our customers have lasting peace of mind. Details will be provided with your estimate.
We use Schedule 40 PVC or ABS that meets local code, joined with approved fittings and shielded no-hub couplings at transitions. For lining, we use epoxy-saturated liners rated for many years of service.
Common causes include tree root intrusion, especially from older trees in established neighborhoods. Basements are common in Colorado, and shifting soil can crack floor drains, sewer lines, and foundation walls over time. Deterioration of older cast iron or clay pipes, grease buildup from improper disposal and foreign objects flushed down drains also lead to blockages and breaks.
Most spot repairs are completed in one day, including excavation and backfill. Larger replacements or jobs that need a city right-of-way permit can take two to four days. We give you a timeline before we begin.
To prevent future sewer line problems, avoid flushing anything other than toilet paper, dispose of grease properly and be mindful of what goes down your drains. Consider having yearly professional drain cleaning or sewer inspections, especially if you have older pipes or mature trees near your sewer line. Regular maintenance can catch small issues before they become major problems.
Common signs include recurring drain clogs, multiple fixtures backing up, foul odors coming from drains or the yard, gurgling noises from toilets, unusually lush patches of grass in your yard or dips in your lawn. If you notice any of these, especially combined with slow drains, it's wise to call for a professional inspection soon.
Roots typically enter through existing gaps at joints, then expand as they grow. Over time they can crack clay pipe, separate joints and create a full blockage. Cutting roots helps short-term, but sealing or replacing the joint is the lasting fix.
