Como Park Sewer handles trenchless sewer repair and pipe bursting in St. Paul, MN and across the East Twin Cities metro. On the right pipe, trenchless replaces the entire lateral through two 4-by-4-foot access pits instead of a full open trench. Your lawn, your driveway, and most of the public street stay intact. Every job starts with a camera inspection so you know exactly what we are about to do and why.
What We Do
We install a new full-diameter HDPE sewer pipe through your existing lateral without digging up the whole line. The method is called pipe bursting: a hydraulic bursting head is pulled through the old pipe on a steel cable, fracturing the old pipe outward into the surrounding soil while the new pipe is drawn in right behind it. When the pipe is structurally intact and only has cracks or root intrusion, we can use CIPP lining instead, which needs only one access point and cures a resin sleeve inside the existing pipe.
Both methods leave your yard, driveway, and street largely undisturbed. What you see when we leave is two small backfilled pits (bursting) or one small pit (lining), a raked-out yard, and a video of the finished line.
How It Works
- Call us and describe what your line is doing. Slow drains, recurring backups, or sewage in the basement all warrant same-day dispatch.
- We run a camera through the full length of the lateral and mark the exact failure points above ground. The camera also confirms whether trenchless is viable at all.
- You get a written fixed price with the specific method (pipe bursting or CIPP lining), the number of feet, permit costs, and asphalt-restoration line items called out separately.
- We pull the St. Paul Public Works road-opening permit if the work touches the street, dig the small access pits, and complete the bursting or lining pull. Total time on site is typically one to three days.
- We backfill, restore asphalt or concrete where needed, and walk you through the final camera footage before we close the job.
When Trenchless Is the Right Call for St. Paul Homes
The pipe condition decides, not the price tag. Trenchless is the right method when a camera inspection confirms the lateral meets four conditions: the pipe still holds its general shape, no point is offset by more than the pipe wall thickness (about half an inch on a 4-inch lateral), no section is missing entirely, and no crushed segment sits under a heaved sidewalk panel or a tree stump.
For older Como Park, Cathedral Hill, and East Side St. Paul homes with clay-tile laterals from the 1890s through the 1950s, the gating question is joint separation. A joint that has gapped by three-eighths of an inch can still be lined; a joint that has settled a full inch or more into a bellied section cannot, and pipe bursting is the honest call.
Why St. Paul Homes Benefit Most from Trenchless
Three Twin Cities-specific factors make trenchless especially valuable here.
The frost line runs 42 inches minimum, 60 to 72 inches in severe winters per NOAA National Weather Service Twin Cities records. Every lateral repair is deep work regardless of method. Trenchless still requires deep access pits, but two 4-foot-square pits are far less excavation than a 60-to-100-foot trench.
Saint Paul Regional Water Services puts the homeowner on the hook for the lateral all the way to the wye connection at the public main. That means most full-lateral repairs touch the pipe under the public street. A trenchless access pit is a single 4-by-4-foot cut near the curb. A traditional open-trench repair is a full-width trench across the street, and asphalt restoration on that scale can add thousands to the bill.
Twin Cities winters freeze the ground from November through March. Both methods still work through winter, but trenchless is faster to warm up because the excavation footprint is smaller. When a lateral fails in January, trenchless is often the only method that can complete inside a normal weather window.
What It Costs
Total Twin Cities trenchless jobs typically run $4,000 to $18,000 depending on lateral length, pipe condition, and whether the work crosses the public street. See our full St. Paul sewer line repair cost guide for the per-foot breakdown and how trenchless compares to traditional open-trench excavation line by line.

For pipes that are still fully intact and just need a resin liner to seal cracks or seal out roots, CIPP sewer pipe lining is usually the lower-cost trenchless option. If a camera inspection shows a fully collapsed section, full sewer line repair or replacement with open-trench excavation is the correct call. Not sure yet? Start with a sewer camera inspection so the pipe itself tells us which method fits.
