A Real Sociedad youth graduate, Gajate played solely for the Basque club, making his first-team debuts on 1 January 1978 at Valencia CF. He appeared very rarely for the back-to-back La Liga champions – only four matches combined – as he was barred by another youth graduate, Alberto Górriz, but gradually carved a starting XI niche, going on to form an historical centre-back partnership with the former.
After only missing three games combined from 1986 to 1988, adding five goals, as Real won the Copa del Rey in one season and finished league runner-up in the other, Gajate retired in June 1992, having appeared in 364 top flight matches (469 overall).
