The mature landscaping on La Jolla properties has big root systems, and under many of these yards those roots found the older sewer lines a long time ago. The way in is usually simple, a joint that opened a hairline over the decades, or a seam the ground settled apart. The problem builds out of sight until a drain slows, then stops.
Clearing treats the symptom but not the cause. Roots come back through the same opening, and repeat visits get old fast. The longer lasting fix is a targeted one. The camera helps identify the entry, shows how far the intrusion goes, and gives you the evidence for a fix sized to what's there, sealing the joint or repairing the section, and choosing an approach that disturbs the garden above as little as possible.
You'll see the footage, hear every option with its tradeoffs in plain English, and make the decision at your own pace, with the work performed by or under a licensed contractor when you're ready.
