Yes, nearby construction absolutely can damage your sewer line, especially if you have a sewer easement running through a neighboring property. Heavy equipment, excavation, and ground shifting can crush, crack, or misalign your line. A common early warning sign is sewage backing up into your basement tub or floor drain.
A homeowner in Vienna, VA recently called us with exactly this situation. Construction had started on the lot next door, and weeks later, sewage was backing up into their basement tub. They suspected the work had disrupted a sewer line easement crossing the neighboring property. It is more common than most people realize, and acting quickly is the right call.
At Hicks Plumbing Services, we help homeowners diagnose and resolve these situations before they turn into costly structural or health hazards. Here is what you need to know.
Why Does Construction on a Neighboring Property Affect Your Sewer Line?
Many homes have sewer line easements that run beneath or through adjacent properties, and those lines are vulnerable when excavation or heavy equipment work begins nearby.
An easement gives your sewer line the legal right to pass through someone else’s land, but it does not make the pipe immune to physical damage. Digging, grading, or driving heavy machinery over the ground above your line can:
- Crush or crack the pipe
- Shift pipe joints out of alignment
- Introduce debris or soil into the line
- Change the slope of the line so waste cannot flow properly
Even if no direct contact is made with the pipe, ground vibration from equipment can loosen connections over time.
What Are the Warning Signs That Your Sewer Line Has Been Disrupted?
The most telling sign is sewage or wastewater backing up into the lowest drain in your home, which is almost always a basement tub, floor drain, or utility sink.
Your sewer system works by gravity. When a blockage or break occurs underground, wastewater has nowhere to go but back up through the path of least resistance. Watch for these signs:
- Sewage smell in your basement or near floor drains
- Slow drains throughout the house, not just one fixture
- Gurgling sounds from toilets when other drains are running
- Visible sewage or dark water in a basement tub or floor drain
If you are seeing more than one of these at the same time, that is a strong signal of a mainline issue, not just a simple clog. Our sewer line repair and replacement team can run a camera inspection to confirm exactly what is going on underground.
What Should You Do Right Away if You Suspect Construction Damaged Your Line?
Stop using water in your home as much as possible and call a licensed plumber to perform a sewer camera inspection before the damage gets worse.
The longer sewage has no clear path out, the higher the risk of it backing up further into your living space. A camera inspection gives you a clear picture of what happened, where the problem is located, and whether it is a blockage or a structural break in the pipe.
You should also document everything. Take photos or video of the backup. Keep a written record of when construction started and when symptoms appeared. If the damage was caused by the neighboring construction, that documentation becomes important when dealing with contractors, insurance companies, or legal claims.

Frequently Asked Questions
Is it my responsibility to fix a sewer line that runs through a neighbor’s property?
Generally, yes. Even if the line crosses someone else’s land through an easement, the homeowner who owns the line is typically responsible for its maintenance and repair. However, if a third party caused the damage through negligence, such as a contractor who ignored your warnings, you may have grounds to seek compensation. Consult a plumber first to document the damage, then speak with a legal professional about your options.
Can a sewer camera inspection confirm whether construction caused the damage?
A camera inspection can show exactly where a break, collapse, or blockage is located and what it looks like. While it cannot legally assign blame, it does produce visual evidence of the pipe’s condition and the nature of the damage, which can support your case if you need to pursue a claim.
Is sewage backup in a basement a health hazard?
Yes. Sewage contains bacteria and pathogens that pose real health risks. You should limit contact with the affected area, keep children and pets away, and call a plumber as soon as possible. Ventilate the space if you can do so safely.
