All the details are at the bottom of our site under Shipping & Return Policy. You'll find everything about returns, freight damage, and any brand-specific rules.

Shipping estimates are just that — estimates, and they're not guaranteed. Weather, freight delays, and carrier issues can throw things off, especially with bigger items. If you're on a tight timeline for installation, it's smart to give yourself some wiggle room.

Just reach out to us after your purchase and we'll connect you with trusted installers in your area. You can negotiate pricing and scheduling directly with them, or we can help coordinate the whole process for you.
