The typical Commack home was built in 1964, 6 years older than the Suffolk County median of 1970. Housing age matters for garage doors because it decides the opening size, whether the door still runs on extension springs, and how much headroom the track has.
Commack’s 1960s housing
Commack’s homes mostly date to the 1960s and 1970s: the median is 1964 and only about 31% predate 1960 (Census). About 93% are detached, about 94% are owner-occupied and the median value is about $678,000. About 78% of households have two or more vehicles and about 31% have three or more.
The typical Commack garage is attached to a split-level or colonial, with a two-car door and an opener that has been replaced once or twice.
A 1950s core inside a 1960s town
Commack’s Census profile has a split personality. Almost none of its housing predates 1940 (about 1%), but about 28% was built in the 1950s, a much bigger postwar core than the median year of 1964 suggests. So the hamlet has two kinds of garages: early single-car garages on the 1950s streets, where extension springs and narrow openings still turn up, and two-car attached garages on the later split-levels and colonials. Ask whether a tech has worked on your era of house before pricing an extension-to-torsion conversion ($450 – $850 published) or a new two-car door ($2,500 – $2,950).

Commack is one of the hamlets split between towns. The western part is in the Town of Huntington and the eastern part in the Town of Smithtown. Repairs don’t need a permit either way. For a door that changes the opening, check your tax bill and call the right office.
