Full Maintenance vs. Oil-and-Grease: Which Elevator Contract Type Do You Need?

There are three basic types of elevator maintenance contracts: full maintenance (the contractor covers most parts and labor for a flat monthly fee), parts-and-labor limited (a hybrid with caps or exclusions on certain components), and examination-and-lubrication, often called "oil and grease" (basic inspection and lube, with repairs billed separately). The right choice depends on your equipment's age, your building's risk tolerance, and your capital budget, not just the monthly price on the proposal.

I've reviewed hundreds of these contracts over 24 years, and the most common mistake I see is building owners choosing based on the monthly number alone, without understanding what happens the day a hoist motor or controller board fails.

Full Maintenance Contracts: What You're Actually Buying

A full maintenance contract means the elevator company agrees to maintain, repair, and in many cases replace worn components at no additional charge, for a fixed monthly fee. In theory, if a door operator, controller board, or hydraulic valve fails, it's covered.

Typical monthly pricing runs $250 to $600+ per elevator, depending on equipment type, unit count, region, and whether the building has hydraulic or traction elevators. Hydraulic units on the low end, high-rise traction and MRL (machine-room-less) systems on the high end.

The catch: "full maintenance" is a marketing term, not a legal standard. Every contract defines coverage differently, and most exclude things like:

• Cosmetic finishes (cab interiors, fixtures, flooring)
• Code-driven upgrades (mandated by local or state authorities)
• Vandalism or misuse damage
• Items deemed "obsolete" that require modernization instead of repair

We've seen contracts labeled "full maintenance" that still billed the owner $18,000 for a controller replacement because the contract defined controllers as excluded once they're more than 15 years old. That's why reading the actual exclusions list matters more than the contract's title. Our maintenance contract review guide walks through exactly which clauses to check line by line.

Parts-and-Labor Limited Contracts: The Middle Ground

This hybrid model covers routine parts and labor but caps coverage on major components, or excludes them entirely above a certain dollar threshold or equipment age. Monthly pricing typically lands $150 to $350 per elevator, meaningfully less than full maintenance.

These contracts work reasonably well for buildings with newer equipment (under 10-15 years old) where major component failure is less likely in the near term. The savings can be real if your elevators are modern and well-maintained.

The risk shows up as equipment ages. A parts-and-labor limited contract on a 20-year-old hydraulic elevator can leave you paying full price for a pump unit or jack replacement, the exact repairs most likely to occur at that age. We generally recommend building owners request a written list of exactly which components are capped or excluded, not just a summary paragraph.

Oil-and-Grease (Examination-Only) Contracts: Lowest Cost, Highest Exposure

Oil-and-grease contracts, sometimes called examination-and-lubrication agreements, cover routine inspection, cleaning, and lubrication only. Every repair, part, and callback is billed separately, usually at the contractor's standard time-and-materials rate.

Monthly pricing is the lowest of the three, often $80 to $200 per elevator, which makes it tempting for owners managing tight operating budgets. But the total cost of ownership can flip dramatically. A single controller board replacement can run $8,000-$25,000 depending on manufacturer and elevator type (KONE, Otis, TK Elevator, Schindler, Mitsubishi Electric, and Fujitec all price proprietary parts differently). If you're on an oil-and-grease contract, that bill lands entirely on you, with no cap and often on the contractor's schedule rather than yours.

We do see oil-and-grease contracts used sensibly in a few situations: buildings planning a full modernization within 12-24 months, buildings with in-house maintenance staff handling minor repairs, or portfolios with dedicated capital reserves specifically for elevator repairs. Outside those scenarios, it's a bet that nothing expensive breaks, and elevators are mechanical systems that eventually break.

Matching Contract Type to Building Profile

Here's how we generally advise clients to think about it:

• New or recently modernized equipment (0-10 years): Parts-and-labor limited often makes sense. Lower monthly cost, and major failures are less likely.
• Mid-age equipment (10-20 years): Full maintenance is usually worth the premium. This is the window where controllers, door operators, and hydraulic components start failing.
• Aging equipment (20+ years) not yet slated for modernization: Full maintenance, ideally with a clear written exclusions list, or a serious conversation about the modernization timeline instead of continuing to patch old equipment.
• Equipment scheduled for modernization within 24 months: Oil-and-grease can be defensible if you're managing cash toward the capital project, but budget for repair calls in the interim.
• Buildings with low elevator traffic and strong reserves: Any tier can work, though we'd still lean toward parts-and-labor limited as a baseline.

It also depends on your equipment age and contract terms in ways a generic comparison can't fully capture, which is one reason we look at the actual proposal rather than category labels alone.

The Number That Actually Matters: Response Time and Exclusions, Not Just Price Tier

Contract type is only half the picture. We've reviewed full maintenance contracts that were worse deals than parts-and-labor limited contracts from a competing vendor, because of buried clauses around:

• Response time guarantees (or lack thereof) for breakdown calls
• Overtime and after-hours billing on "covered" repairs
• Automatic renewal terms and price escalation clauses
• Definitions of "obsolescence" that let the contractor decline repairs

This is exactly the kind of detail that's easy to miss when you're comparing three quotes side by side. If you want a structured approach to comparing proposals across vendors, our guide on getting competitive elevator bids is a good starting point, as is our breakdown of contract red flags.

Get an Independent Read Before You Sign

If you're staring at a proposal and can't tell whether "full maintenance" actually means full maintenance, or whether the parts-and-labor limits leave you exposed, that's exactly the gap our $499 flat-rate independent review is built to close. We'll go through the contract line by line, flag the exclusions that matter for your specific equipment age, and tell you plainly whether the price matches the coverage.

Frequently Asked Questions

Is full maintenance always the better choice?

Not always. For newer equipment with low failure risk, you may be paying a premium for coverage you rarely use. It depends on equipment age, unit count, and how much repair risk your building is willing to carry.

Can I switch contract types mid-term?

Most contracts lock you in for a set term (often 1-5 years) with renewal or termination clauses that dictate when you can switch. Review the termination language carefully, ideally before you need to use it.

Do all vendors define "full maintenance" the same way?

No. Definitions vary significantly between contractors, and even between contracts from the same company in different markets. Always request the written exclusions list, not just marketing language.

How do I know if my current contract is a good deal?

Compare the monthly rate against your building's elevator pricing benchmarks for your region and equipment type, then check the exclusions list against your equipment's age and known failure points.

What if my building has a mix of old and new elevators?

It's common to split contract types across a portfolio, full maintenance on aging units and parts-and-labor limited on newer ones. A single blanket contract sometimes isn't the most cost-effective structure.
