Sewer Lines Under San Anselmo Homes
In San Anselmo, houses sit close together, with the lateral under the driveway or front steps. Trenchless work avoids breaking that concrete.
What we run into in San Anselmo
- Aging pipe. Plenty of laterals around San Anselmo are older than the people living above them. Age alone is often what finally opens the joints.
- Tree roots. Mature trees send roots toward the warm, damp air leaking from a cracked joint. Once inside, they grow into a mat that catches everything.
- Concrete over the line. On compact San Anselmo lots the lateral usually runs under concrete for part of its length, which is where an open trench gets expensive.

Call (833) 529-2616Sewer Line Failures We See Around San Anselmo
These are the failures behind most calls for trenchless sewer line repair in San Anselmo, CA. A camera pass usually shows which one you have.
Root intrusion at the joints
Roots enter through cracked or loose joints and grow into a mat. They are cut out, then lining seals the joints.
Cracked or offset pipe
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.
Toilets gurgle or bubble
Air pushed back through the trap when other fixtures drain means the line is partly blocked downstream.
Backup in the lowest drain
Sewage rising in a floor drain, shower or basement fixture is the line telling you it cannot carry the flow.
Sewer smell outside
A smell near the cleanout or over the yard can mean a cracked pipe venting gas into the soil.
Can't tell which one you have? Describe what the drains are doing, and the likely cause comes back on the call.
Line It or Burst It? Deciding in San Anselmo
Lining suits a pipe that still holds its shape: cracks, root entry, corrosion and small offsets. Bursting suits a pipe that is collapsed, flattened or too small, because it replaces the line rather than coating it.
Still unsure which way your line will go? Call (833) 529-2616 with the age of the house and what the drains are doing. You will hear what a camera inspection is likely to show before anyone comes out.

San Anselmo Homes by the Numbers
About 42% of homes in San Anselmo were built before 1950, when sewer laterals were commonly clay tile or cast iron, materials that crack, separate at the joints and let roots in as they age. Homes from 1950 to 1979 make up about 46% of the stock, an era with mixed lateral materials, and the median year built across San Anselmo is 1954. About 78% of homes are single-family and 68% 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.
With about 12,711 residents on roughly 2.7 square miles (near 4,761 per square mile), San Anselmo is suburban in density, with a mix of detached homes and townhomes. It is number 345 by population of the 619 California places on our service list.

What are the disadvantages of trenchless pipe lining?
Lining cannot pass a full collapse or lift a sagging section, and it takes a little off the inside diameter. Bursting or a targeted dig handles those.
How long does trenchless pipe lining last?
Cured-in-place liners are engineered for about 50 years. HDPE pipe pulled in by bursting is rated for 50 to 100 years.
How long does trenchless sewer repair take?
One day for most homes, occasionally two. Expect the water to be off for a few hours while the liner cures.
