Garage Supply Guys Frequently Asked Questions

If something's not working out, just let us know. Keep in mind that some items might have a restocking fee. Check the product page for the specifics.

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.

Make sure whatever you're buying will actually fit your space. That means checking ceiling height, floor space, power requirements, and whether freight delivery can even get to your location. Trust us, it's way easier to confirm these details upfront.

Read through the product details carefully, especially for heavy or specialized items. If you're not sure about fit, shipping, installation, or anything else, just ask. We'd rather help you get it right the first time.

You'll get a confirmation email right away once you place your order. For most items like car lifts, parts, and shop tools, we'll have them shipped out within five business days if they're in stock. This goes for all major brands and replacement parts.

We don't offer installation services ourselves, but we can put you in touch with qualified installers in your area who you can work out pricing with directly. We can also handle this for you after your purchase.

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.

Some items can be installed by experienced DIYers, but larger equipment like car lifts typically require professional installation for safety and warranty reasons. Check the product specifications and manufacturer requirements before deciding.

Yes! We're authorized dealers for all the major brands we carry. This means you get full manufacturer warranties, genuine parts, and proper support. You can always verify our dealer status directly with the manufacturer if you'd like.
