Cabins, second homes and 1970s frames
This is tourist country, and plenty of properties around Keystone and Hill City appear to be cabins, rentals or second homes rather than full-time residences. We haven't confirmed the numbers, but if that describes your place, a few things change:
- Access. Installers need to measure in person and come back to install. Plan who will be on site.
- Lead. Many 1970s cabins have pre-1978 paint on trim and sills. The installer must be an EPA Lead-Safe Certified Firm.
- Frames. Older wood openings in shaded, pine-covered lots can hide rot. Full-frame replacement lets the installer open it up and repair it.
- Views. Picture windows and bay or bow windows are common on rooms facing the hills; picture units run $300–$1,600 each (Fixr, Jan 2026).
Many owners here also price wood-clad or fiberglass windows to suit a timber or mountain-style exterior.
On the way: Colonial Pine Hills
Between Rapid City and the central Hills, the Colonial Pine Hills subdivision is almost entirely owner-occupied (98.7%), with a 1990 median build year and most homes from the 1990s (37%) and 1970s (27%). Requests from there fit the same pattern as Hill City: aging first-generation vinyl, plus lead-safe work in the older houses.
Before hiring, ask for an SD contractor's excise tax license number (DOR, 1-800-829-9188) and proof of insurance. We couldn't confirm local licensing rules for Hill City or Keystone, so ask the installer to check, and to confirm permits with the town or Pennington County. Rapid City Window Pros doesn't verify licenses.
