Sewer Lines Under Longmont Homes
In Longmont, winter frost reaches well into the ground, which makes excavation slow and hard on the yard. Lining and bursting need only small access points.
What we run into in Longmont
- Basement exits. Basement floor drains are usually the first place a failing sewer line shows itself, because they are the lowest opening in the house.
- Deep frost. Freeze-thaw cycles move the soil around older pipe and open joints. Trenchless repair can go ahead without a long frozen trench.

Call (833) 529-2616Sewer Line Failures We See Around Longmont
When people phone about trenchless sewer line repair in Longmont, CO, the line nearly always has one of these faults. Each has its own best method.

Root intrusion at the joints
Cutting roots clears the pipe for a while; a liner removes the joints they get through, so they stay out.

Breaks and shifted joints
Cracks, holes and joints that have slipped out of line leak and snag waste. Lining covers them with new pipe.

Corroded or collapsing pipe
Old pipe that is scaling, flaking or losing its round shape is relined if it still holds its form, or replaced by bursting.
Several drains slow at once
One slow sink is a local clog. Tubs, toilets and sinks slowing together point to the main line.
Toilets gurgle or bubble
Air pushed back through the trap when other fixtures drain means the line is partly blocked downstream.
Clogs that keep coming back
If the line needs snaking every few months, something in the pipe, usually roots or a break, is catching waste.

Line It or Burst It? Deciding in Longmont
If the old pipe is intact enough for a liner to follow, lining is usually the least disruptive fix. Where it is crushed, Orangeburg or badly out of round, pipe bursting pulls a new HDPE line through the same route.

Longmont Homes by the Numbers
Only about 6% of homes in Longmont were built before 1950, so most laterals here are later materials, which tend to fail at joints and connections or from roots and ground movement rather than from old clay. Another 32% were built between 1950 and 1979, a stretch when cast iron, clay and fiber (Orangeburg) laterals were all still in use, and the median home overall dates from 1990. About 70% of homes are single-family and 63% are owner-occupied; the lateral from the building to the city connection is generally the owner's responsibility, so the repair-or-replace decision is usually theirs.
Longmont covers about 29 square miles and holds roughly 98,958 residents, around 3,382 per square mile: suburban in density, with a mix of detached homes and townhomes. Among the 111 Colorado places we cover, it ranks number 11 by population.

Trenchless Sewer Line Repair in Longmont, CO: FAQs

Didn't see your question?
Ring us. A sewer technician picks up, and quoting over the phone costs nothing.
Call (833) 529-2616How much does trenchless sewer line repair in Longmont, CO cost?
Most lines cost an estimated $4,000 to $15,000 to line or burst, or about $80 to $250 per foot. A spot repair is estimated at $1,500 to $4,000, and the camera inspection at $150 to $500. Where a line is deep below a basement or frozen ground, access costs more, and that is on the written quote.
Can a sewer line be replaced without digging?
Almost. Trenchless methods use one or two small access points instead of a trench, and lining can sometimes run entirely from an existing cleanout.
What are the signs of a broken sewer line?
Watch for several slow drains together, gurgling toilets, backups in floor drains, sewer smell in the yard, wet or greener strips of lawn, and repeat clogs.
What are the disadvantages of trenchless pipe lining?
A liner follows the old pipe, so it cannot fix a collapsed section or a belly that holds water, and it narrows the bore slightly. Those cases call for bursting or a short dig.
