At Greenfield Finishing, we are continually looking to improve our processes and services.  A while back, we had the dream of creating Pre-Built Window Trim, with the goal of reducing on-site labor and mess.  After a good amount of research and testing, we're excited to offer this cost-effective innovation to clients and contractors, alike.   For our Pre-Built Window Trim, we begin by taking accurate measurements of the window being used.  Next, the jam and casing are all assembled in our shop.  Nail holes are filled, the wood is primed, and then the trim is ready to be sent to the job site.
