A serious line problem in a newer home can feel almost unfair when the house is only 20 years old. After 20 years, though, maturing landscaping can finally reach the depth of the line.
The contractor's inspection sorts out a young line's problems, a root intrusion at a joint the landscaping finally found, a low spot from settling, construction debris left from the build, or a section that needs repair on its own. Full replacement enters the conversation only when the evidence puts it there. The inspection shows whether the problem is one section or the whole line, which is exactly the kind of thing you want to know before anyone quotes anything.
Everything gets explained in plain English, every option with its tradeoffs. The decision is yours, made at your pace, with a licensed contractor performing the work when you're ready.
