If your garage door suddenly refuses to move. or lurches halfway up and stops. there's a good chance a spring has failed. In Los Altos Hills, it happens more than you'd think. Homes here range from 1950s ranch-style estates in neighborhoods like Country Way and Fremont Hills to grand Mediterranean villas built during the dotcom boom, all the way up to modern custom builds with oversized three-car doors. The heavier and more elaborate the door, the more stress gets placed on the springs every single day.
Understanding what's going on before you call a technician will save you time, money, and a lot of frustration.
Your garage door doesn't lift itself. the torsion spring or extension springs do the heavy work. Torsion springs sit horizontally above the door opening and store mechanical energy as they wind and unwind. Extension springs run along the horizontal tracks on either side and stretch as the door closes. Both types are under enormous tension at all times.
Most standard residential springs are rated for about 10,000 cycles. roughly 7 to 10 years of daily use. Higher-cycle springs can reach 25,000,50,000 cycles, and for homes in Los Altos Hills with multiple cars and busy households, the upgrade is often worth it.
Don't wait for a full break. Watch for these warning signs:
- The door opens unevenly or one side droops. This usually means one spring has weakened or snapped while the other is still holding. - The door feels extremely heavy when lifted manually. A properly balanced door should stay open on its own at about waist height. If it falls, the springs aren't doing their job. - A loud bang from the garage. Many homeowners describe a broken torsion spring as sounding like a gunshot. a sharp crack that sometimes happens in the middle of the night. - Visible gaps or separation in the spring coil. A torsion spring with a visible gap in the middle has broken and must be replaced before the door is used again. - The opener is straining. If your motor is working overtime to lift the door, worn springs are often the culprit. Left unchecked, this can burn out the opener entirely.

Los Altos Hills has a Mediterranean climate. long dry summers and wet, unpredictable winters. While the area sees only about 20 inches of rain per year, the wet season matters. Moisture accelerates corrosion on uncoated springs, especially on doors that face north or sit under heavy tree cover (common on hillside properties near Rancho San Antonio). Nearby Palo Alto homeowners deal with the same issue.
Beyond weather, the sheer weight of doors on larger homes is a real factor. A solid wood carriage-style door on a Los Altos Hills estate can weigh 400 pounds or more. These doors require heavier-gauge torsion springs, and when those springs fail, the door doesn't just stall. it can crash down fast.
Torsion springs are the modern standard and the right choice for most Los Altos Hills homes. They provide more balanced lifting, last longer, and are generally safer when they break because a containment rod prevents the coil from flying loose. Most newer and mid-century remodeled homes here will already have torsion systems.
Extension springs are found on older doors and lighter one-car setups. They're less expensive to replace, but they don't last as long and can be more hazardous if they snap without a safety cable installed.
Honest answer: more than the national average. In the Bay Area, a single torsion spring replacement runs approximately $200,$500 including labor. If you have a two-car door requiring dual springs. which is the standard on most Los Altos Hills homes. expect to pay more. Labor rates here are higher than in most of California, and rightly so: this is not a DIY job.
A practical tip: always replace both springs at the same time, even if only one has broken. The second spring is under the same amount of cumulative stress and will likely fail within months. Replacing both in a single service call costs far less than two separate visits.
Garage door springs are under hundreds of pounds of torque. A torsion spring that releases suddenly can cause serious injury. Professional technicians have specialized winding bars, containment tools, and the training to set the correct tension for your specific door weight. This is one of the few home repairs where the risk genuinely outweighs any cost savings.

Springs cannot be welded or patched. once the coil separates or loses its tension, full replacement is the only real option. The good news is that a proper replacement with high-cycle springs is genuinely a long-term fix, not a patch job.
If your springs are intact but the door is still misbehaving, the issue may be with cables, rollers, or the opener itself. A technician can diagnose the actual cause quickly. often in the first few minutes of inspection. You can also browse our FAQ page for common diagnostic questions before your appointment.
Most standard springs are rated for 10,000 cycles, which typically translates to 7,10 years. Homes with multiple vehicles and frequent daily use may see springs wear out faster. Upgrading to high-cycle springs (25,000,50,000 cycles) is a smart investment for busy households, especially given the heavier doors common on larger Los Altos Hills estates.
No. Operating a garage door with a broken spring puts extreme stress on the opener motor and cables, and the door can drop suddenly without warning. Disconnect the opener and leave the door closed until a technician can inspect it.
Always replace both. Even if only one spring has broken, the other is likely near the end of its life. Replacing both in a single visit saves money on labor and prevents a second service call in just a few months.
