Springs and cables form one system — the counterbalance — and they take each other down: a weak spring overloads the cables, a fraying cable unbalances the spring. Alfonso's inspection weighs the door against its spring rating, checks every inch of cable, and re-tensions as needed, so failures become appointments instead of emergencies. $85–$165 in San Francisco.

Not to the day, but meaningfully. Springs are rated in cycles — commonly around 10,000 — so door age and daily usage give a solid estimate of consumed life, and the balance test shows how much lift the spring has already lost. Visible rust pitting and stretched coil gaps sharpen the picture. "You're in the last 10–20% of this spring's life" is a genuinely useful thing to know before it bangs.
At the bottom, almost always — the last few inches near the bottom bracket see the tightest bend and, near the coast, the most trapped moisture. You can look without touching: broken strands sticking out like whiskers, rust-brown staining, or a flattened section all mean the cable is failing. Look only, though; the bottom brackets are under full spring tension.
There's overlap, honestly — the tune-up includes a working check of springs and cables. This inspection goes a level deeper: we weigh the door, compare against the spring's rating, examine cable condition end to end, and re-tension the system. It earns its keep on doors over eight years old, heavily used doors, and homes near the ocean where corrosion compresses every timeline.
