Trenchless Sewer Repair & Replacement
Replace a broken or root-clogged sewer line without tearing up your yard. A-1 Trenchless uses pipe bursting and pipe lining to install a brand-new sewer line — no-dig, WSSC-licensed, and often finished in a single day.
How Trenchless Sewer Replacement Works
Traditional sewer replacement means an open trench across your lawn, driveway, and landscaping. Trenchless does the same job through one or two small access points. With pipe bursting, we pull a new seamless pipe through the old line while it fractures the old pipe outward; with cured-in-place lining (CIPP), we form a new pipe inside the old one. Either way, you get a full-strength sewer line without the demolition.
It starts with a camera inspection to confirm the line is a trenchless candidate and locate the problem exactly. Then our WSSC-licensed crew installs the new pipe, tests the flow, and cleans up. Most homeowners keep their driveway, patio, mature trees, and hardscaping fully intact — and the job is done in far less time than a dig-and-replace.

Trenchless Sewer Repair
Pipe bursting and CIPP pipe lining replace a failed sewer line with no digging up your yard — a brand-new pipe, often in a single day.
Sewer Line Descaling
Mechanical descaling scours years of rust, scale, and buildup out of old cast-iron pipe, restoring full flow without a full replacement.
Sewer Camera Inspection
High-definition CCTV video inspection pinpoints breaks, roots, bellies, and blockages exactly — a free sewer video inspection before any work begins.
Hydro Jetting & Drain Cleaning
High-pressure water jetting cuts through grease, roots, and hardened debris to fully clear drains and main lines — far beyond what a cable snake can do.
Water Line Repair & Replacement
Repair or replacement of leaking, aging, or lead water service lines — trenchless where the line allows, and restored clean when excavation is needed.

What Our Customers Say
Trusted by homeowners across Montgomery County & the DC metro
A-1 replaced our collapsed sewer line with pipe bursting — no trench across the yard. Camera inspection first, honest estimate, and done in a day. Saved our driveway and our lawn.
Recurring backups for years. A-1 hydro-jetted the main line and showed me the before/after on camera. Completely clear now. Wish I'd called them first.
Old cast-iron pipe was almost fully scaled shut. They descaled it instead of pushing a full replacement — flow is back to normal and they saved us thousands. Honest crew.
Free camera inspection found the exact break under the walkway. Trenchless replacement meant no demolition. Professional, licensed, and fair. Highly recommend.
Water service line was leaking and pressure was terrible. A-1 replaced it and restored the yard with seed and straw. You'd barely know they dug. Great work.

Bought an older home and had A-1 do a sewer camera inspection before closing. Caught a bellied line the home inspector missed. That inspection paid for itself many times over.
Prompt, WSSC licensed, and they explained everything with the camera footage. No upselling. Cleared a root-clogged line and gave me options. Trustworthy company.
Main sewer replacement done trenchlessly. The crew was respectful, clean, and finished faster than I expected. The yard was left in great shape. Would use again.
Descaling brought our 1950s cast-iron drains back to life. They camera-scoped before and after so I could see the difference. Excellent, honest service.
From the free estimate to the finished job, A-1 was straightforward and skilled. Trenchless sewer repair with zero damage to the landscaping. Couldn't be happier.
