No worries, we've got you covered. We can send replacement parts or arrange for a new delivery. Just make sure to inspect everything when it arrives and give us a heads up right away if something's off.

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.

Most larger items like car lifts and heavy equipment ship free, but depending on the brand there might be freight costs. Smaller items almost always have shipping fees via UPS, USPS, FedEx, etc. We'll show you any extra costs before you check out.

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.

Yep! Once it ships, we'll email you the tracking info so you can keep tabs on your delivery and plan accordingly.

We always send tracking info once your order ships. If it's been more than five business days and you haven't heard anything, just shoot us a message at support@garagesupplyguys.com or hit us up through the Contact Us page. We'll figure out what's going on.

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.
