cheap and free renovation materials before you pay full retail

sources that actually had usable stuff when I checked, not just 'try craigslist'

01
the one near me has had actual usable kitchen cabinets twice this year. call ahead, inventory turns fast
02
Facebook Marketplace
search 'renovation' and 'demo', not just the material name. contractors dump stuff there constantly
03
Craigslist free section
less traffic than marketplace now but still where I found a stack of oak flooring for the cost of a truck rental
04
OfferUp
05
Nextdoor
neighbors posting 'come take this before the trash truck does' is more common than you'd think
06
local salvage yard
every town has one, ours is unmarked behind the lumber yard. cash only, bring a truck
07
asking the crew on a neighbor's job site
asked a deck crew for their offcuts, walked away with enough joist hangers for the shed. costs nothing but the ask
08
city bulk trash pickup week
(rental-friendly) check your city's calendar and go the night before, not the morning of
09
