The Best Repair Is the One You Catch Early

A garage door that passes a visual inspection can still fail a balance test. A door that opens and closes without drama can have a spring 200 cycles from breaking, cables fraying at the drum, or rollers worn enough to jump the track next week. A professional diagnostic catches these conditions before they become emergency repairs — or worse, safety incidents.

What We Check

20-Point Safety Inspection

Spring System Condition

Visual condition of torsion spring(s), coil spacing, rust, and fatigue signs. We assess estimated remaining cycle life based on wire gauge, observed wear, and known cycle history.

Balance Test

The most important test most homeowners never do. Disconnect the opener and release the door at mid-height. A properly balanced door holds position. A door that drops or rises has a spring tension problem — and an opener working overtime to compensate for it.

Cables & Drums

Cable condition (fraying, kinking, corrosion), drum wrap pattern, and cable attachment at the bottom bracket. Fraying cables are a critical-severity finding — they can snap without further warning under load.

Rollers & Hinges

Roller condition, stem wobble, bearing wear, and hinge pivot wear. Worn rollers create noise, drag, and track wear that compounds over time.

Track Alignment

Vertical track plumb, horizontal track pitch, and the gap between roller and track edge. Track even slightly out of alignment accelerates roller wear and can cause binding or derailment.

Opener Force Settings & Auto-Reverse

Closing force must be set so the door reverses when it meets resistance at the ground — a UL 325 code requirement. Over-tightened force settings are how doors injure people and damage vehicles. We test and set this correctly every time.

Safety Sensors (Photo-Eyes)

Alignment, cleanliness, and proper reverse response. These are code-required on all openers manufactured after 1993. Misaligned or dirty sensors cause erratic behavior or refusal to close.

Seals & Weatherstripping

Bottom seal condition, perimeter weatherstrip on jamb and header. Poor seals admit water, pests, and cold air — all fixable at low cost if caught before they cause bigger problems.
