Jose and his team were a pleasure to work with. I highly recommend JING to anyone looking for a contractor in the Denver area.
JING was helpful in every aspect of our build out. Detail oriented, very professional and easy to work with. Highly recommended for any future projects you may have.
Easily the best experience I've had with a design firm. Jose provided a comprehensive, high-fidelity model and scale of our remodel that made the vision clear from the start.
I highly recommend JING. Jose is a very competent and honest contractor. I've known him for a long time and I would recommend him whenever the opportunity arises.
Would highly recommend Jose and his team for any home renovation projects. After I bought my house they helped with multiple jobs including painting and cosmetic bathroom updates.

Site walk, zoning review, scope alignment. We confirm what's buildable and what your investment looks like before any drawings begin.
Floor plans, massing, and elevation studies. Decisions get made here — before we commit to construction documents.
Full plan set with structural and Title 24 coordination. Sealed, stamped, and ready for the city.
