When you book garage door balance adjustment in Mill Valley, you get a tech who knows Marin County — Marin County reaches north from the Golden Gate across coastal hills, redwood canyons, and bayside towns. We serve Tamalpais Valley, Strawberry and Almonte and nearby Corte Madera, Larkspur, Ross, and Sausalito every day.
We spec every Mill Valley job for the environment it lives in. Given warm, dry summers and cool, wet winters, moderated by long stretches of sunshine and modest rainfall, the failure modes we plan around are fine road and yard grit that grinds rollers over time, wide day-to-night temperature swings that loosen hardware, and long dry spells that crack aging weatherstripping — and we carry the corrosion-resistant parts to match.
We've fixed thousands of doors around Marin County, and the pattern holds in Mill Valley: dried, cracked bottom seals from constant UV, drifting travel limits on aging chain-drive openers, sun-faded, brittle weather seals along the bottom panel, and corroded low brackets on homes near the coast. None of it should leave you without a working garage for more than a day.
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.

Frequently asked about garage door balance adjustment
Top questions homeowners searching for Garage Door Balance Adjustment near me ask us:
Mill Valley sits in warm, dry summers and cool, wet winters, moderated by long stretches of sunshine and modest rainfall. That is hard on a door — fine road and yard grit that grinds rollers over time, wide day-to-night temperature swings that loosen hardware, and long dry spells that crack aging weatherstripping all accelerate wear on springs, seals, and openers, so the failures we see most here are dried, cracked bottom seals from constant UV, drifting travel limits on aging chain-drive openers, sun-faded, brittle weather seals along the bottom panel, and corroded low brackets on homes near the coast. We size springs and seals for California's Mediterranean climate region conditions rather than a generic catalog spec.
Census data puts 81% of Mill Valley homes at pre-1980 construction (median build year 1957) — old enough that many garages still run their original springs, opener, and seals, all long past rated life.
Yes — out-of-balance doors are the #1 cause of premature opener failure we see. Restoring balance is the highest-leverage maintenance task short of spring replacement.
Disconnect the opener (red emergency-release cord). Lift the door to chest height. Release. A balanced door stays put. Drifts down: under-tensioned. Drifts up: over-tensioned.
We strongly discourage it — torsion springs are dangerous to wind without the right tools and training. The professional service price is small compared to the injury risk.
Balance adjustment is quoted flat-rate on its own, and is usually included when combined with spring replacement or cable repair.
