New property managers inherit a lot in the first month. Keys, codes, alarm panics nobody wrote down correctly, and a stack of service contracts in a binder somebody left in the bottom drawer. Every line already has a vendor name, a price, and a renewal date circled in somebody else's handwriting. HVAC. Landscaping. Elevator maintenance. Window cleaning. By the time you've made it through onboarding, you've already made sixty small decisions you didn't even know you were making, and leaving the vendor list untouched doesn't feel like one of them. It feels like the one thing that's already handled.
That's exactly the problem.
Nobody chose this vendor for you. Somebody just never got around to un-choosing them.
That's not a knock on your predecessor, and it's not really about window cleaning specifically. It's about how contracts survive inside busy organizations. Reviewing a vendor mid-year, when nothing looks visibly wrong, isn't urgent. It never is, right up until the year it should have been. A new property manager showing up with a fresh set of eyes and zero loyalty to the incumbent is about the best chance that contract has had to actually get looked at in years. Most new PMs let that chance slide right on by without ever realizing it was there.
Here's a thought experiment worth sitting with a minute. Picture two buildings. Both have used the same window cleaning vendor for three years running. Both contracts renewed automatically, on schedule, without incident.
In Building A, the vendor shows up on time, documents every visit, flags anything unusual (a failing seal, a cracked pane, a sprinkler head spraying the wrong direction), and answers the phone when something's off. The three-year streak reflects three years of trust that's actually been earned.
In Building B, the vendor shows up, does a fine enough job, never really communicates beyond the invoice, and nobody at the property has looked too close at what's actually being delivered versus what's being billed. The three-year streak just reflects three years of nobody checking.
From the outside, from the binder a new property manager inherits, these two contracts look about identical. Same tenure, same "no issues reported," same renewal date circled in the same pen. The file can't tell you which building you're standing in. Only a real review can.
That's the trap of "no complaints." A property manager who's never fielded a complaint about window cleaning often figures that quiet means the service is fine. But tenants rarely bother escalating window cleaning to the property office at all. It reads as too small a thing to mention, right up until it isn't. Dirty entrance glass, streaking, a missed cleaning cycle here and there: most of that just gets absorbed as background annoyance, never logged anywhere you'd see it. An empty complaint file isn't proof of good service. It's proof that nobody's been asked the question straight out.
Here's the part that ought to make you a little uneasy: reviewing a window cleaning vendor isn't purely a spending decision. It's a liability decision too, and once you're the property manager of record, part of that liability belongs to you, whether or not you're the one who originally hired the outfit.
The industry safety standard covering window cleaning, ANSI/IWCA I-14.1, doesn't put all the responsibility on the contractor. It requires the building owner, which in practice usually means whoever's managing the property day to day, to provide written assurance "that the installation or structure has been inspected, tested and maintained in compliance with the requirements of this Standard," and it states plainly that a "window cleaning contractor shall not permit employees to perform window cleaning prior to receiving assurance from the building owner" that the building's own anchor points and equipment meet the standard.
Read that again, slow. The standard assumes the building owner is actively checking compliance before work starts, not just trusting that whatever's already in place is fine because it's been fine so far. If your building has rooftop anchors, davits, tie-back points, any permanent fall-protection setup at all, you now share documented responsibility for whether that equipment still holds up, no matter how long the current vendor's been using it without a hitch.
Most new property managers have never laid eyes on an anchor point inspection certificate for their own building. Most have never asked for one. That's not unusual, it's just the default. But "unusual to ask" and "fine not to ask" are two different things, and only one of them holds up if something ever goes wrong up on that roof. If a technician got hurt tomorrow using equipment nobody had checked in years, "the last manager set this up" isn't a position anybody wants to be defending. The honest answer to "is our anchor system compliant?" shouldn't be "probably, since nothing's happened yet." It should be a piece of paper with a date on it.
There's a quieter reason inherited vendors rarely get a second look, and it's worth saying plain: reopening a vendor relationship feels like a bigger hassle than it is, and switching feels riskier than staying put, even when staying put is the actual risk. This shows up in how organizations handle vendors generally, not just window cleaning. Decision-makers default to the incumbent because the incumbent is known, and "known but mediocre" tends to beat "unknown but maybe better" every time a real decision has to get made.
New property managers are especially prone to this, because everything in that first year is new territory. Reviewing a vendor contract has to compete for attention against a dozen genuinely urgent things: a lease renewal, a capital project, an HVAC unit on its last leg. Window cleaning, which fails quiet and hardly ever triggers an emergency, loses that fight by default, every single time, unless somebody deliberately pulls it forward instead of leaving it to inertia. Budget season is what pulls it forward. Outside of budget season, there usually isn't a mechanism that does.
The contract you were handed will tell you a price. It almost certainly won't tell you:
A fourth question worth tacking on, especially for bigger or high-rise properties: who's actually on the crew, and is it the same crew every visit, or some rotating subcontractor deal nobody's ever mentioned to you? Consistency matters for accountability. A vendor who can't tell you who's up on your roof is a vendor you haven't really vetted yet, no matter how long they've held the contract.
If you can't answer those questions about your current vendor right now, you don't have a vetted vendor. You've got an unexamined one, wearing the credibility of a multi-year renewal it never actually had to earn fair and square.
You don't need some dramatic reason to put a vendor under review. A service failure, a tenant complaint, a sudden price hike, none of that's required. Budget season is the reason. It's the one stretch of the year where going through every line item isn't overstepping, it's expected of you as part of the job. Skip it here, treat the current setup as settled just because it's familiar, and the next natural checkpoint is a full year out. Twelve more months of a vendor relationship nobody's actually tested.
A renewed contract tells you what happened last time somebody looked. It doesn't tell you what would happen if you looked now.
That's the review worth doing before this year's budget locks in. Not because the current vendor's necessarily wrong, but because "we've always used them" isn't a finding. It's the absence of one, dressed up to look like a decision somebody actually made.
Building your first budget and stuck vetting a vendor relationship you didn't get to choose? Bring us your current contract and we'll walk it against actual scope and documentation with you. No pressure, no pitch, just another set of eyes before you sign off on 2027
