Our secret passageways are designed to be installed in minutes anywhere in the world. They come pre-hung in their own door frames which simply slide into the rough door opening as though it were a typical appliance. If you can install a conventional pre-hung door, you can install one of our secret passageways.We also provide unlimited free technical support for installers! At the client's request, we can even have a Lake Green Group installation team physically travel to a job site anywhere in the world to assist with the installation. To ensure that each passageway fits perfectly, Lake Green Group provides each client with detailed shop drawings prior to ever starting fabrication. The drawings clearly show the size, shape, and power requirements (where applicable) of the project and required rough door opening.While Lake Green Group builds the passageway the contractor on the site can simultaneously prepare the rough opening. Lake Green Group also provides each client with 3D illustrations depicting what the proposed secret door will look like in both the open and closed positions. This ensures that we precisely match the client's vision and there will be no surprises. It also gives the client the opportunity to request free design changes without incurring any change order fees.

Each project is prefitted into a special test jig that precisely mimics the opening at the job site to ensure a perfect fit. We then perform life-cycle testing, take photographs, and inspect it prior to shipping. Each project will arrive at the job-site pre-assembled and ready to install.
