COMMON QUESTIONS
Clear answers before the work starts.
Do you use a drain camera?
When the line is accessible and a camera will help answer the question, we can use video inspection to document the condition.
Can roots cause recurring backups?
Yes. Root intrusion can restrict or damage older laterals. The repair path depends on the location and severity.
Is a blockage the same as a flood-protection issue?
No. A blockage, damaged lateral and municipal sewer surcharge are different problems and can require different solutions.
