There's a version of landlording where things just... break. The tenant calls, you scramble, you pay whatever it costs to fix it fast because you have no other choice. The repair is always expensive, the timing is always terrible, and somehow it always seems to happen in December.
Most landlords live in that version for years before they realize it doesn't have to be that way.
The landlords who stop hemorrhaging money on emergency repairs aren't lucky — they just figured out that a little bit of scheduled attention is almost always cheaper than a crisis. Not slightly cheaper. We're talking the difference between a $150 service call and a $4,000 replacement.
Here's the preventive maintenance rhythm that actually works, broken down by season.
Spring: Come Out of Winter Ready
Winter is rough on rental properties. Once the cold breaks, you want to get eyes on everything that took a beating.
HVAC checkup. This is non-negotiable. Have the system serviced before the first hot stretch of the year. A technician will clean the coils, check refrigerant, and catch anything that's worn. The $100–$150 service call is your insurance policy against a $3,000 emergency replacement in July — when every HVAC company in town has a two-week waitlist.
Roof and gutters. Walk the perimeter and look up. Ice and snow can lift flashing, loosen shingles, and push debris into gutters. Clogged gutters force water back under the roofline, and that water finds its way inside. A gutter cleaning costs next to nothing. Water damage to ceilings and walls costs a lot.
Exterior and foundation. Look for cracks, gaps where pipes or wires enter the building, and any place water could pool near the foundation. Small gaps let in moisture, pests, and cold air — all of which become someone else's expensive problem later if they're not sealed now.
Test smoke and CO detectors. While you're doing the seasonal walkthrough, replace batteries and test every detector. It takes five minutes, costs almost nothing, and covers you legally and personally.
Summer: The Quiet Season — Use It
Summer is when most landlords relax. That's fine, but spend a little of that time on the things that are easy to overlook when everything seems to be running smoothly.
Plumbing inspection. Check under sinks, around toilets, and anywhere there's a supply or drain line. Look for the slow drips that tenants stop noticing after a week. A small leak under a kitchen sink can silently rot out the cabinet floor and subfloor for months before anyone says anything.
Pest prevention. Summer is when things get in. Walk the perimeter and seal any gaps, especially around the foundation, doors, and utility penetrations. An $80 preventive treatment beats a $1,500 extermination job with a side of drywall repair.
Check your water heater. Most water heaters are invisible until they fail dramatically — usually by flooding a utility closet. If yours is 8–10 years old, it's living on borrowed time. Flush the tank to clear sediment (sediment makes the heater work harder and fail faster), and inspect the anode rod. A water heater replacement on your schedule runs $600–$1,200. On the tenant's emergency schedule, with water cleanup, it runs considerably more.
Fall: Before the Cold Comes
Fall is the most important maintenance window of the year, full stop. What you do now determines how your winter goes.
Heating system service. Mirror what you did with AC in spring. Get the furnace or heat pump serviced before it has to run hard. Replace filters. Clean ducts if it's been a few years. A heating system that fails in January isn't just expensive — it's a potential habitability issue, with legal implications depending on your state.
Weatherization. Check door and window seals. Replace weatherstripping that's cracked or compressed. Caulk around windows where the seal has pulled away. This is one of the highest-return maintenance tasks there is — your tenant's utility bills drop, comfort goes up, and you protect the building envelope from moisture intrusion.
Exterior faucet shutoffs. If your property is in a climate that freezes, make sure exterior faucets are winterized and the shutoff valves inside actually work. A burst exterior pipe can run hundreds of gallons before anyone notices.
Dryer vent cleaning. This one gets skipped constantly and it shouldn't. Lint buildup in dryer vents is a legitimate fire hazard and a surprisingly common one. It also makes the dryer run longer and harder, burning out the heating element faster. Annual cleaning takes 30 minutes.
Winter: Stay Ahead of the Cold
Your job in winter is mostly about monitoring and not getting caught off guard.
Keep the heat on in vacant units. This seems obvious but it's easy to cut corners when a unit is between tenants. The minimum to prevent pipe damage is around 55°F. One burst pipe from a vacant unit that nobody was watching can cost more than months of utility bills.
Check in with tenants. A quick message asking if there are any drafts, heating issues, or anything dripping goes a long way. Tenants often sit on small problems because they don't want to bother you, or they assume it'll resolve itself. It won't.
Clear drains and downspouts. Ice dams and blocked downspouts cause serious water damage to roofs and fascia. If you're in a snowy climate, a post-storm walkthrough is worth your time.
The Part Nobody Talks About: Actually Following Through
A maintenance schedule only works if you actually do it. That sounds obvious, but the reason most landlords don't follow a schedule isn't laziness — it's that the information lives in too many places. One property's notes are in a spreadsheet, another's are in an email chain, and the last HVAC service date is “sometime last spring, I think.”
The landlords who are genuinely on top of this stuff have one place where every task, every property, and every service date lives. When it's time for the fall furnace service, they already know the last time it was done, who did it, and what the tech said. When a tenant calls about a dripping faucet, they can see at a glance when plumbing was last inspected.
That's the system we built LandlordKeep around — not just reminders, but a complete maintenance history for every unit, so nothing slips and no $200 task quietly turns into a $6,000 repair.
Because that's always how it happens. Not all at once, but gradually, until suddenly it's a lot.
