Garage Door Repair in Sunnyvale, CA
Sunnyvale has been rebuilt on top of itself for four decades — second storeys, additions, reframed openings, whole houses taken back to the studs — and that leaves a specific garage door problem behind. A great many doors here are hanging in an opening that has been altered since they were fitted, on hardware specified for a house that no longer exists. We reach Sunnyvale in under 60 minutes with South Bay crews off US-101.

A remodel changes things a door cares about even when nobody touched the door. Adding a second storey changes the load path and can shift a header; reframing an opening for a wider vehicle changes the width but rarely the springs; insulating and drywalling a garage changes the clearances the tracks were set for; and a new slab or a raised floor changes where the door has to seat. The result is a door that ran perfectly for fifteen years and has been slightly wrong ever since the work — and because it happened during a project when everything was disrupted, nobody connects the two. It is the most common diagnosis we deliver in this city, and owners are almost always surprised by it.
The second consequence is mismatched hardware. When a wider or heavier door goes in during a remodel, the springs and opener frequently do not get re-specified — they get reused, because they were working. A door that is even slightly under-sprung is out of balance on every cycle, which the opener absorbs by working harder and the cables absorb by wearing unevenly. We weigh the door and check the balance before touching anything, and on a remodelled house that check finds a problem more often than not.
Underneath the remodels, Sunnyvale is orchard-era ranch homes and mid-century tracts — including several Eichler neighbourhoods, where the door is a wide, flat, deliberate plane in a low façade and is unforgiving of a track that has drifted. The climate is dry inland: hot summers that perish weatherstrip and dry seals, cold mornings, no meaningful corrosion.
