Torsion-spring re-tensioning so the door holds at half-open without drift. Prevents premature opener failure, eliminates the slam, and recovers the auto-reverse safety margin.
Garage Door Garage Door Balance Adjustment Sunnyvale, CA
We tailor garage door balance adjustment to Sunnyvale's housing and climate. With mainly suburban houses with attached two-car garages, mixed with some older central-neighborhood homes and a temperate dry-summer climate — sunny, low-humidity afternoons and a short, mild rainy season, the durable choice is rarely the cheapest part — and we'll explain why.
Sunnyvale sits in California's Mediterranean climate region — a temperate dry-summer climate — sunny, low-humidity afternoons and a short, mild rainy season. That puts real stress on garage door hardware: we routinely see long dry spells that crack aging weatherstripping, winter damp that rusts low brackets and fasteners, and dry-season dust that works into open tracks, and we fit parts rated to handle it.
Across Cherry Chase, Ortega Park, Birdland and Heritage District, what brings Sunnyvale homeowners to us is sun-faded, brittle weather seals along the bottom panel, frayed lift cables on aging sectional doors, noisy, vibrating doors from loosened hardware, and drifting travel limits on aging chain-drive openers — and we resolve it without a second visit.
Garage door balance is the relationship between door weight and counter-weight (spring tension). When the door is correctly balanced, a fully disconnected opener should let the door rest stationary at any position you put it in — half-open without drifting up or down. When out of balance, the door drifts down (under-tensioned) or drifts up (over-tensioned), and the opener has to work harder than designed every cycle. Out-of-balance doors are the #1 cause of premature opener failure we see in the field.
Balance drifts over time as springs lose modest tension with cycling, as cables stretch slightly, and as panels accumulate weight (insulation added later, repaired panels with slightly different weight). A balance adjustment visit measures the actual door weight, calculates the correct spring tension, and re-winds the springs to spec. We also check cable tension and drum spool count as part of the same service.
After adjustment, we verify auto-reverse on a 1.5-inch obstruction test (UL-325 baseline) and re-program the opener's force and travel limits to match the new balance. The whole visit is 60–90 minutes. Done right, balance adjustment can add years to the opener's life and noticeably smooth out door operation.
Under-tensioned springs let gravity overpower the counter-weight. Opener compensates but the door still impacts hard at close.
Opener strains on lift
Heavy opener motor sound during open cycle indicates the springs aren't providing enough lift assistance.
Door drifts down when stopped halfway
The classic balance test — disconnect opener, lift door to half, release. Drift down = under-tension. Drift up = over-tension.
Door reverses before fully closing
Modern openers reverse when they detect resistance. Out-of-balance increases the apparent resistance, triggering premature reversal.
New spring installed but not balanced
A spring replacement without proper balance check is a partial job. Always re-balance after any spring work.
Common causes & what we fix
Spring fatigue
Springs lose 5–10% of tension over their cycle life. Re-tensioning recovers the original balance.
Cable stretch
Cables elongate slightly under load over time. Stretched cables change effective door travel and balance.
Weight added after install
Insulation foam, additional panels, or hardware adds weight that the original spring wasn't sized for.
Improper original install
Builder installs occasionally use the wrong spring size. Balance check reveals and corrects.
Damaged panel adding weight
Water-damaged or replaced panels can weigh differently than the original. Balance re-tunes for the new weight.

Balance adjustment alone: $109–$149. Combined with spring replacement or cable repair: usually included in the larger service price.
