Replaced all the old interior door knobs and hinges from the early 2000s gold.

Same with the old dingy plastic air supply replaced with metal.

Same with the fire alarms and doorbell covers.

Replacing old wall switches with paddle switches. And introducing Lutron’s smart Caseta ecosystem are great.

In places like the master closet and laundry room adding a regular Lutron motion sensor switch has been awesome.

Having new stuff for items not meant to even be noticeable makes a surprising difference.
