Here is a quick list of the top drain services we offer:
Signs You Have a Sewer Line Problem
Sewer line issues often start subtly before becoming serious. Watch for multiple slow or backed-up drains throughout your home, sewage odors inside or outside your home, unusually lush or wet patches in your yard over the sewer line, gurgling sounds from toilets or drains, or sewage backups in your lowest-level fixtures. If you notice any of these signs, don’t wait. Contact 128 Plumbing, Heating, Cooling & Electric immediately. In many cases what starts as a slow drain is actually a main sewer line issue. Learn more about our drain cleaning service in Chelmsford.
Sewer Camera Inspection: Know Before You Dig
Before recommending any repair, 128 Plumbing, Heating, Cooling & Electric uses professional sewer camera inspection technology to get a clear view inside your pipes. This allows us to pinpoint the exact location and nature of the problem, whether it’s a root intrusion, a crack, a bellied section, or a blockage. This also helps us recommend the most effective and least disruptive repair method. Our full range of drain services is available across our service area.
Trenchless vs. Traditional Sewer Repair
Depending on the nature and location of the damage, 128 Plumbing, Heating, Cooling & Electric offers both trenchless pipe lining and traditional excavation repair. Trenchless methods use an epoxy liner to seal cracks and restore pipe integrity from the inside, with minimal disruption to your yard, driveway, or landscaping. For more severe damage, traditional excavation may be the most effective solution. We’ll explain both options clearly. Learn more about our trenchless pipe lining service.

Frequently Asked Questions
Why choose 128 for sewer line repair in Chelmsford, MA?
Since 1992, 128 Plumbing, Heating, Cooling & Electric has provided professional sewer line repair services throughout Chelmsford and surrounding communities. Our experienced plumbers use advanced camera inspection technology to accurately diagnose sewer problems and recommend the most effective repair solution, including trenchless options when appropriate.
How do I know if my sewer line is broken?
Common signs include multiple slow drains, sewage odors inside or outside your home, wet spots or unusually green patches in your yard, gurgling sounds from toilets, or sewage backing up into lower-level fixtures. A sewer camera inspection is the most accurate way to identify the cause and location of the problem.
How much does sewer line repair cost in Chelmsford?
Costs vary depending on the repair method, the location and severity of the damage, pipe accessibility, and whether trenchless repair is possible. We provide a detailed diagnosis and upfront pricing after completing a sewer camera inspection.
What is trenchless sewer repair and how does it work?
Trenchless pipe lining involves inserting a flexible, resin-coated liner into the damaged sewer pipe and inflating it against the existing pipe walls. Once cured, the liner forms a durable new pipe within the old one, restoring functionality while minimizing excavation and disruption to your property.
How long does sewer line repair take?
Many trenchless sewer repairs can be completed within a single day. Traditional excavation repairs may require one to three days depending on the complexity of the project, the depth of the sewer line, and site conditions.
Does homeowner’s insurance cover sewer line repair?
Standard homeowner’s insurance policies typically do not cover sewer line failures caused by age, wear, or tree root intrusion. Some policies offer optional sewer line protection coverage. We recommend reviewing your policy details and speaking with your insurance provider to determine available coverage.
