Castle Rock rules and tips5
THE LOCAL ANSWER
For up to 5 gallons of house paint, stain or varnish, use a PaintCare store in town, such as Moore Lumber on Park Street or Sherwin-Williams on Plum Creek Parkway. For spray paint, thinner or a bigger load, book a free slot at Douglas County GreenWorks, 5675 Delva Way, Sedalia (up to 10 gallons per visit).
In Castle Rock, Colorado, you have two choices: a PaintCare store in town, or Douglas County's new GreenWorks hazardous waste drop-off in Sedalia. The county announced household hazardous waste drop-off there on August 4, 2026. It's free for Douglas County residents by appointment and takes spray paint and thinner too.
GreenWorks replaced the old yearly limit
Douglas County announced year-round household hazardous waste drop-off at GreenWorks on August 4, 2026. The county says this ends the old yearly participation cap. It's open Monday to Saturday, 8 a.m. to 5 p.m., by reservation only, and free with proof of Douglas County residency.
Book early and check daily
Reservations open about a week ahead (the page also says ten days) and fill fast. Call 303-660-7480 for help. Bring your confirmation email and proof of residency. You unload your own items onto a cart, so bring someone who can lift.
Four PaintCare stores in town
PaintCare's data lists Sherwin-Williams at 175 Plum Creek Pkwy and 3845 Ambrosia St, Moore Lumber and Hardware at 1335 Park St, and Moore Hardware and Lumber at 4401 Regent St. Most take 5 gallons per visit. Spray paint and thinner are not accepted at stores.
The Town doesn't collect trash
Castle Rock has no town trash or recycling service. Your HOA or your own hauler (the Town names HBS Trash and Waste Management) handles pickup. For chemicals, the Town points residents to Douglas County. The Town also lists a community recycling center at 701 Prairie Hawk Drive (Saturdays, 10 a.m. to noon), but not for paint.
Home pickup for more than 10 gallons
PaintCare's Colorado page says that "for a limited time" households in certain counties, including Douglas, with more than ten gallons of paint, stain or varnish can get a free pickup. Call 720-854-8722 to see if you qualify. PaintCare's listing says households only, no businesses.
Free pickup programs and other options
Contractors and businesses with 100 gallons or more can ask PaintCare for a free large-volume pickup. Businesses can't use GreenWorks. Douglas County's page also names GreenSheen Paint at 1055 S. Jason St. in Denver as a place that takes more than 5 gallons. The Town co-hosted a free paint event with GreenSheen on September 13, 2025, at Douglas County High School. We found no 2026 event.
Getting your paint ready
Keep paint in the original labeled can, lid tight. For GreenWorks: containers of 5 gallons or less, 10 gallons total, nothing mixed, nothing leaking. For stores: 5 gallons per store and no spray cans. Pack cans upright in a sturdy box.
Full preparation checklist →Castle Rock questions5
Where can I drop off paint in Castle Rock?
At PaintCare stores like Moore Lumber (1335 Park St) and Sherwin-Williams (175 Plum Creek Pkwy), or by appointment at Douglas County GreenWorks in Sedalia.
Is GreenWorks free?
Yes, for Douglas County residents. You need an appointment and proof of residency.
Does GreenWorks take spray paint?
Yes. Its list includes latex and oil-based paint, stains, varnishes, aerosols and thinners.
How much paint can I bring to GreenWorks?
The county's page says containers up to 5 gallons and 10 gallons total per visit. PaintCare's listing shows a higher limit, so plan on the county's 10.

Sources and how we checked7
Checked October 16, 2026: Douglas County's GreenWorks Household Hazardous Waste page (hours, accepted items, 5-gallon container and 10-gallon visit limits, residency, terms, alternate options including GreenSheen), the county's August 4, 2026 news release, the Town of Castle Rock's Other Services page (no town trash service; chemicals to Douglas County), the Town's September 13, 2025 paint event listing (past), PaintCare's Colorado page (door-to-door counties include Douglas), PaintCare's locator data (four Castle Rock stores, GreenWorks record 18138, door-to-door record 11446) and Colorado CDPHE's program list (still describes Douglas County spring and fall events). Conflicts: PaintCare lists a 100-gallon limit and phone 303-663-6274 for GreenWorks, while the county page says 10 gallons per visit and gives 303-660-7480; the county page says reservations open both 'ten days' and 'a week' ahead. PaintCare's listing for Moore Lumber on Park Street shows no per-visit limit. Not settled: how long PaintCare's door-to-door offer lasts; whether the Town plans another paint event.
