Knowing how to vet a lift installer matters more than almost any other decision you make when you buy a vehicle lift, because the hardware is only as safe as the hands that anchored it. We are Auto Lift Services, based in Ames, Iowa, and we install, inspect, and repair lifts across the state and the surrounding region every week. A large share of our service calls are cleanup jobs: anchors set in bad concrete, columns out of plumb, hydraulic lines routed where a floor jack will eventually crush them, or paperwork that never got filed so the shop has no inspection record at all. This guide is the checklist we would want a stranger to use on us.
We stock parts and complete lifts for every major brand, and we install what we sell. Call 800-674-9302 if you want a straight answer about a quote you already have in hand.
Start With Certification, Not With Price
The first question on any list of how to vet a lift installer is whether the person doing the work holds a current ALI Certified Lift Inspector credential or documented factory training from the brand you are buying. Those are two different things and both matter. Factory training means the tech has been walked through that manufacturer’s specific torque values, shimming procedure, and cable routing. ALI certification means they have been tested against the national inspection standard and can legally sign an annual inspection record that your insurer and your state inspector will accept.
Ask for the certificate number and the expiration date, not just a verbal yes. Credentials lapse. We have walked into shops where the installer’s card expired four years before he set their columns, and the shop had no idea because nobody asked. Price is the last thing to compare, not the first. A bid that comes in dramatically under everyone else usually means one of three things: the crew is not carrying the right insurance, they are skipping the concrete verification step, or they are planning to bill the extras back to you later as change orders. We would rather lose a job on price than explain to somebody why their two-post is leaning.
Verify Insurance and Workers’ Comp in Writing
Anyone crawling around your bay with a rotary hammer and a thousand-pound column needs general liability coverage and workers’ compensation, and you need to see the certificate of insurance with your business named as a certificate holder. Not a photo of a card. An actual COI issued by their carrier. If a helper gets hurt in your shop and the installer has no comp coverage, your policy becomes the deep pocket, and your carrier will not be gentle about it.
Coverage limits matter too. Setting a 12,000 lb two-post over a customer’s truck is a real exposure. We carry limits appropriate to commercial installs and we send the paperwork before we schedule, because shop owners who have been through a claim always ask. If an installer hesitates, deflects, or tells you insurance is not necessary for a one-day job, that is the whole answer. Also ask who is actually showing up. Some outfits sell the install and then subcontract it to whoever is available that week, which means the credentials you vetted belong to a person who will never touch your equipment. Get the crew named in the work order.
Ask How They Evaluate Your Concrete
Concrete is where most bad installs are born. A competent installer asks about slab thickness, compressive strength, cure time, control joint locations, and whether the slab sits on properly compacted fill before they ever quote the job. Most two-post lifts want a minimum of four inches of 3,000 PSI concrete, and heavier capacities want more. In older Iowa buildings, especially ones that started life as grain storage or a repurposed farm shop, we routinely find three-and-a-half inches over dirt with no rebar anywhere.
The right answer is to core or at least drill test holes and measure. The wrong answer is to eyeball it and start shooting anchors. If a bidder never mentions concrete, they are not evaluating your building, they are just selling labor hours. Ask what happens if the slab fails the test. A real installer will already have a plan: cut and pour a properly sized footing pad, tie it into the existing slab, and wait the full cure before setting columns. That adds days and cost, and honest people tell you up front instead of discovering it on install morning. Our approach to two-post installation always starts with the floor, because anchors do not care how much you paid for the lift.
Get the Scope in Writing, Line by Line
A vague quote is a future argument. The written scope should name the lift model and capacity, spell out who supplies and runs the electrical, who pulls permits if your jurisdiction requires them, who handles air lines, whether overhead or floorplate configuration is being installed, what the anchor spec is, and who hauls away the crate and pallets. Freight is another line that gets fudged constantly. Ask whether the price includes liftgate delivery, inside delivery, or curbside drop where you are responsible for getting an 800-pound column off a semi.
We also spell out the commissioning steps: full cycle test, safety lock engagement check at every position, cable tension and equalization, hydraulic bleed, torque verification on every anchor, and a signed initial inspection sheet handed to you at the end. That document is your baseline. Without it, your first annual inspection has nothing to compare against. When people ask us how to vet a lift installer, we tell them to read the quote like a contract instead of a price tag, because that is exactly what it is. Anything not written down is not included, no matter how friendly the phone call was.
Call References From Shops That Look Like Yours
References are worth something only if they match your situation. A residential garage install tells you very little about whether a crew can handle a four-post in a low-ceiling commercial bay or a heavy-duty setup for a fleet shop. Ask for two or three customers with similar equipment, similar building age, and similar capacity, and then actually call them. Ask what went wrong, because something always does, and listen to how the installer handled it.
The follow-up question we would ask is about service after the install. Did they come back for the annual inspection? Did they answer the phone when a lock stopped releasing on one corner? Plenty of outfits will install a lift and vanish, leaving you to find somebody willing to service equipment they did not sell. We would rather be the people you call for the next fifteen years, which is why we stock parts for every major brand instead of only what we sell. If you are still narrowing the field, our broader guide to choosing a lift installer covers the comparison side in more depth, and there is a companion piece specific to choosing a lift installer in Iowa for local building and code considerations.
Watch for the Red Flags That Actually Predict Problems
After enough repair calls, patterns show up. The installers who cause trouble tend to share the same tells. They want full payment before any work happens. They cannot name the brands they are factory-trained on. They quote over the phone without asking a single question about your building. They tell you an ALI inspection is optional. They arrive without a torque wrench, a rotary hammer with a proper bit gauge, or a laser level, and they borrow tools from you. They shim with whatever scrap is lying around instead of proper steel shims.
Another quiet red flag is anchor substitution. The manufacturer specifies a diameter, embedment depth, and anchor type for a reason, and swapping in cheaper wedge anchors from the hardware store voids the certification and the warranty. Ask which anchors they will use and cross-check it against the manual, which every reputable manufacturer publishes free. Learning how to vet a lift installer is largely learning which questions make an unqualified bidder uncomfortable. If somebody gets defensive when you ask for a COI, a certification number, or a written anchor spec, you have your answer without needing a second opinion. Our approach to a four-post installation is documented the same way, for the same reason.
Confirm Long-Term Support Before You Sign
The install is one day. Ownership is a decade or more. Before the deposit clears, find out what happens on year three when a cable frays or a power unit starts weeping fluid. Does the installer stock parts or does everything come from a factory order with a two-week lead time? Do they perform ALI annual inspections themselves, or will you be hiring a second company? What is their response window for a down lift, and do they charge a trip fee across the state?
We answer those questions the same way every time: we keep cables, cylinders, power units, arm assemblies, lock components, and hardware on the shelf in Ames, and we service brands we did not sell because a shop with a dead bay is losing money by the hour. That is the practical end of how to vet a lift installer, and it is the part most buyers skip because it does not feel urgent during the sales conversation. It becomes urgent the morning a lock stops engaging with a customer’s vehicle in the air. Anybody serious about how to vet a lift installer should treat parts availability and inspection capability as part of the purchase price. If you want a second set of eyes on a quote you already have, call us at 800-674-9302 and we will tell you honestly whether it is a fair bid, even when the answer is that somebody else beat us on it.
