Residential Delivery & Unloading +

Most residential deliveries are curbside or end-of-driveway by appointment.

The trucking company typically does not unload the crate, bring it inside, move it to a backyard, or place it in the final location.

The freight carrier may not be able to back into certain driveways, private roads, narrow roads, or restricted-access locations.

Optional white-glove or in-home placement is not included in standard delivery. If requested, Between Living may help coordinate a separate third-party service, quoted and paid separately where available.

If assembly, construction, plumbing, or electrical work is needed, the customer is responsible for arranging the appropriate local contractor or licensed professional.

Lead times and build estimates vary by model. We confirm timing at order and share updates once the manufacturer schedules production and shipping.
