What drives the cost of smoke detector install
Number of units
Doing every bedroom and hallway in one visit costs much less per detector than a single install.

Battery units mount in minutes; hardwired and interconnected units require existing wiring or a new run.
Ceiling height and mounting
High or vaulted ceilings need a ladder, and old mounting plates may not match new units.

DIY or hire a pro for smoke detector install?
Small job — know the risk
It looks simple on paper, but shut-off valves that won't close, live circuits, and damage hidden behind the wall are what turn a 30-minute job into a much bigger repair bill. At this price point a pro visit is usually cheap enough that most homeowners just book it and move on.
Most homeowners in this range end up hiring out: the price is fixed before work starts, and the pro who does the job stands behind it.
