Find the section
We run a camera through an accessible line to identify visible damage and understand the pipe around it.

UV pointrepair
A UV-cured internal repair for qualifying localized sewer pipe defects—planned from what the camera actually shows.
The repair, at a glance
First locate. Then decide.
A point repair treats a specific section from inside the line. Whether that approach fits depends on the defect’s location, the condition of the pipe around it and the access available.
01 / SEE
Camera inspection
View the accessible line, locate the area of concern and assess the surrounding pipe before choosing a repair.
02 / ASSESS
Repair suitability
Check whether the defect is localized and whether pipe condition, position and access allow an internal point repair.
03 / REPAIR
UV-cured point repair
For a qualifying section, place the repair from within the pipe and cure it using UV light.
04 / REVIEW
Follow-up camera view
Examine the treated area and walk through what the camera shows after the work.
A targeted approach
Work at the defect, from inside the pipe.
When an inspection identifies a qualifying localized defect, UV point repair offers a way to treat that section internally. It can minimize the need for traditional excavation, but it is not the answer for every damaged line.
Pipe condition + defect location + access determine suitability.
How the work goes
The camera leads the repair.
The inspection comes first. It tells us where the trouble is and whether an internal repair makes sense before work proceeds.
Check the fit
We discuss the defect, its position and the available access. If a point repair does not fit those conditions, we explain why.
Repair and recheck
For a qualifying defect, we carry out the UV-cured internal repair and use the camera to review the treated section.
“The right repair starts with knowing what is actually inside the line.”
Before a point repair
Access shapes the plan.
The camera inspection shows what is happening inside the line. Those findings guide the repair decision and give us a clearer picture before any cost discussion.
Access & suitability
What we need access to
An accessible cleanout or other access point lets the camera and repair equipment reach the damaged section. The camera findings determine whether that section is suited to UV point repair.
If the defect is not localized, the pipe condition is poor or access is limited, cleaning first or excavated access may be needed instead.
Planning the work
What affects cost
- Defect location
- Number of damaged sections
- Pipe condition
- Available access
- Whether cleaning is needed first
Start with the inspection so the discussion is grounded in what the camera shows.
Questions before the work
What homeowners ask about point repair
Can every pipe defect be repaired this way?
No. UV point repair is for qualifying localized defects. The surrounding pipe’s condition, the defect’s location and available access all affect whether it is suitable.
Does an internal repair mean there will be no digging?
An internal repair can minimize traditional excavation. Access still matters, so the inspection is the starting point for understanding what the work may involve at your property.
How do you know where the defect is?
A sewer camera inspection helps locate visible trouble areas in an accessible line. We review those findings before discussing whether a targeted repair fits.
Is this the same as cast iron descaling?
No. Descaling removes buildup from cast iron pipe walls; a point repair addresses a qualifying localized defect. The camera view helps distinguish between those needs.
Start with an inspection
See the pipe before deciding on the repair.
