"Roots had crushed our clay line in North Boulder. They lined it the same week, no trench, no torn-up lawn. Camera footage before and after sold me."

Daniel K. - North Boulder - Trenchless lining
★★★★★

"Sewage was backing up into the basement. They scoped it, found a collapsed section, and gave a flat quote on the spot. Fixed in a day."

Maria T. - Louisville, CO - Spot repair
★★★★★

"Two other companies quoted a full dig. MESA replaced our cast-iron main with pipe bursting and saved the driveway. Honest crew."

What sewer repair involves

From camera inspection to a permanent fix

Every job starts with a sewer camera inspection. We run a scope down the line to see exactly what's wrong, root intrusion, a cracked or broken sewer pipe, a collapsed section, bellied pipe, or an old cast-iron line that's rusted through, and we show you the footage.

Boulder County is hard on sewer lines. Mature tree canopy means aggressive root intrusion into older clay and cast-iron laterals, and decades of freeze-thaw shift and crack pipe joints. Once we've diagnosed it, we recommend the lightest fix that actually solves the problem.

When the pipe path allows, we repair or replace it trenchless. CIPP pipe lining or pipe bursting renews the line through existing access points, with little to no digging. When a line is fully collapsed or off-grade, traditional excavation is the right call, and we'll tell you straight.

Why homeowners choose trenchless

The benefits of a no-dig sewer repair

A trench across your yard isn't the only way to fix a failed sewer line, and usually it's not the best one.

1

Save Your Yard

No-dig lining renews the pipe through existing access, landscaping, driveway, and patio stay intact.

2

A Permanent Fix

A cured-in-place liner is a seamless, jointless pipe rated to last 50+ years, roots can't get back in.

3

See The Problem

A camera inspection shows the exact failure before we quote, no guesswork, no upselling a repair you don't need.

Trenchless vs. traditional dig

What's the difference?

Both methods fix a failed sewer line, but the disruption, timeline, and lifespan are worlds apart. Here's an honest breakdown.

Yard & driveway Trenchless (Recommended) Traditional Open-Trench Dig
Yard & driveway Minimal digging, landscaping stays intact Full trench across the yard, often the driveway too
Time on site Most jobs done in 1 day Several days of digging, repair, and backfill
Pipe lifespan Seamless liner rated 50+ years Depends on material & joints
Total cost Lower once restoration is factored in Pipe is cheaper; landscape repair adds up fast
Cleanup Little to no surface restoration Re-sod, re-pave, re-landscape after

Trenchless isn't right for every line, a fully collapsed or off-grade pipe still needs excavation. After the camera inspection we'll recommend the method that genuinely fits your line and your budget, not the most expensive one.

FAQs

Sewer repair questions, answered

It depends on the problem and the method. A camera-verified spot repair typically starts around $1,500, trenchless CIPP lining around $4,500, and a full replacement from $7,500. Line length, depth, pipe material, and permits all affect the number. We confirm a flat quote after a free camera inspection, you approve it before any work begins.
Trenchless, no-dig sewer repair renews your line through existing access points instead of digging a trench. The two main methods are CIPP pipe lining, a resin liner cured in place to form a new seamless pipe inside the old one, and pipe bursting, which pulls a new pipe through while breaking apart the old. Both leave your yard, driveway, and landscaping largely untouched.
The camera inspection tells us. A single cracked or root-intruded section usually only needs a spot repair or a liner. A line that's collapsed, badly bellied, or rusted through along its length needs replacement. We always recommend the lightest fix that actually solves the problem, and show you the footage so you can see why.
Most trenchless lining and spot repairs are completed in a single day. A full replacement, especially open-trench excavation with permits and backfill, can take two to several days depending on depth and access. We'll give you a clear timeline with your quote.
Two big reasons: tree roots and age. Boulder County's mature tree canopy sends roots toward the moisture in sewer joints, cracking older clay and cast-iron laterals. Decades of freeze-thaw cycles also shift and separate pipe joints. Homes built before the 1980s are especially prone to root intrusion and cast-iron corrosion.
Yes. We scope the full line, locate and mark the exact failure point, and send you the video plus written findings. A standalone sewer scope starts at $199, and it's free when paired with any sewer repair or replacement.
Usually not. When the pipe path allows, we repair or replace trenchless, little to no digging, and your landscaping stays intact. Excavation is only used when a line is fully collapsed or off-grade, and we'll tell you upfront if that's the case before any quote is approved.
Yes to both. We pull permits and coordinate with your municipality on replacement work, and we offer financing through third-party partners so a major repair doesn't have to be paid all at once. We also offer an active-duty military and first responder discount, just mention it when you book.
