What's included
Camera line inspection
We look inside the pipe to identify the exact defect and its location.
Root intrusion clearing and repair
Roots removed and the entry point addressed so it does not return next season.
Broken and offset pipe repair
Cracked, separated or crushed sections replaced.
Sagging and poor-slope correction
Restoring pitch so waste stops pooling in a low spot.
Drainage restoration
Getting the whole run flowing the way it was designed to.
Signs it's time to call
- A drain clogs again within weeks of professional cleaning
- Multiple fixtures back up on the same branch or main line
- You hear gurgling in a toilet when another fixture drains
- Soggy ground, sinkholes or unusually green patches along the drain run
- Sewer odors indoors or near the foundation
- Backups that recur seasonally, often in spring or after heavy rain
Diagnose first, dig only if needed
We start with inspection, not excavation. Knowing whether the problem is a root mass, an offset joint, or a low section changes the repair completely — and often reduces its scope.
You get to see what we found, and a clear explanation of the repair options before anything is opened up.
Older Southern NH housing stock
Many homes in Nashua, Manchester and the surrounding towns have decades-old drain lines running through mature tree cover. Root intrusion and settled pipe are common, and both are fixable.
Drain Repair & Drainage Restoration FAQs
- How do you know whether a line needs repair rather than cleaning?
- Camera inspection. If the line is intact and just fouled, cleaning is enough. If we can see a break, offset or standing water in a sag, cleaning will not hold.
- Do you have to dig up my yard?
- Not always. The repair depends on what the camera finds, and we walk you through the options before any excavation is scheduled.
