Turnkey Framing and Installation Services

We can supply your materials AND install them as well. As one of the first to offer turnkey framing services in the Lancaster area through our partner company Prime Builder Services, GR Mitchell offers you the following benefits:

One Source
By consolidating your supplier and framer/installer, we simplify your entire process. We will handle the scheduling, estimating, take off, delivery, and labor. All the steps are centralized to one source. This allows a much smoother process as well as cost savings through efficiency.

One Price
Another advantage is the single price for the entire job. We will give you one price that will not fluctuate with the rise of building supply costs. This allows you to effectively estimate your costs without any surprises.

Accuracy and Accountability
Each project will have its own supervisor. Our familiarity with our process and use of trusted local laborers allow us to deliver consistent quality results on every project. Since we are responsible for estimating the project, we will pull whatever additional supplies are necessary for the job without additional cost to you.


Many of the building supply items you may see on HGTV may not be available locally, but through our sources we are able to have it sent to our customers. This is one of the many services we offer that ensure your project turns out exactly how you want it.
