Is shipping included in the price?
No. Freight and delivery are quoted separately, based on your location and delivery needs, after we have talked through your project.
How do I get a total price?
Use the estimator. Choose your model, color, base and upgrades and it updates live, including installation. Foundation, site work and travel are confirmed after a site visit, and the estimate is not a binding quote.
