Cold outreach for garage door tune-ups: just blasting texts to neighborhoods and getting ghosted

Been trying cold outreach for garage door services the last few months, mostly texting homeowners about seasonal tune-ups on their LiftMaster openers. I figure if I hit 100 houses a week, something's gotta stick, but man, the response rate is crap. Saw a post on r/HomeImprovement where someone mentioned using NextDoor for leads, so I tried that too, but still mostly nos. Tommy Mello talks about this in his videos, saying persistence is key, but I'm starting to think it's all BS for us small guys. Anyone got a script that actually works for garage door installs without sounding like a spammer? FML, need to tweak my approach before I waste more time.

Hit $50k in new garage door leads last quarter just by door-knocking commercial spots with custom flyers. Feels damn good to see the numbers climb after years of grinding.
