What to maintain, how often, and what it costs you to skip

Written for property managers, owners and HOA boards in Northern Virginia, DC and Maryland. Sources are linked inline and listed in full at the bottom.

Why deferred maintenance is the most expensive kind

Almost nothing on a property fails all at once. A dumpster pad gets sticky before it attracts rodents. A gutter clogs before the fascia rots. A breezeway gets dingy before a prospect turns around in the parking lot. The bill arrives long after the cheap moment to act has passed.

That is the argument for a schedule rather than a reaction. Below is what we actually recommend to the communities we serve, grouped by how often it needs doing, and why each one earns its place.

1. Trash and waste areas — the daily one

Trash is the only part of your property every resident interacts with every single day, and the only part where a two-day lapse becomes a pest problem.

Why containers and lids matter more than people think

The EPA's guidance on rodent prevention is blunt about the mechanism: keep garbage in containers with tight-fitting lids, remove food and water sources, and seal the holes rodents use to get inside — steel wool in small gaps, patched walls for larger ones (EPA, Identify and Prevent Rodent Infestations). Every one of those is a housekeeping task, not an exterminator's task. Once you are paying an exterminator, you have already lost the cheap version of this problem.

What a nightly routine actually prevents

• Bags left in breezeways overnight, which is where the pest cycle starts
• Overflowing compactors that residents photograph and post
• Bulk items abandoned beside the dumpster and billed to you as a special pickup
• Recycling contamination — a bin with the wrong material in it can be rejected at the curb, and the EPA notes that what is accepted varies by local program, so what your hauler takes is a local question worth asking directly (EPA, Frequent Questions on Recycling)

Recommended interval: doorstep collection five to seven nights a week; dumpster pad and enclosure washed quarterly, monthly through summer.

Argos handles this as nightly trash valet — every door, every service night, with recycling staged separately.

2. Exterior washing — and the rule most contractors ignore

Pressure washing is the highest-visibility, lowest-drama improvement you can make to a property. It is also the one with a regulatory catch that catches out cheap contractors.

Your wash water is not allowed in the storm drain

This is the part worth knowing before you hire anyone. Fairfax County's polluted runoff program explicitly lists gray water — including commercial car wash, fleet washing and floor washing wastewater — among the discharges that may not enter the storm drain system (Fairfax County DPWES, Polluted Runoff Inspections). Storm drains here run to streams, not to a treatment plant.

On the Maryland side, WSSC Water's guidance for mobile power washing is more specific still: eligible wastewater goes to the sanitary sewer, either at the job site with the property owner's permission or back at the contractor's own facility (WSSC Water, Mobile Cleaner and Power Washing Best Management Practices, Rev. 10/2019).

Two things follow from that. First, ask any pressure washing contractor how they contain and dispose of wash water — a good one has an answer ready. Second, understand that as the property owner you are the one with the storm drain on your site, which is an uncomfortable place to be if a contractor does it wrong.

What to wash, and when

• Sidewalks, breezeways and entryways — one to two times a year. Twice where shade and damp let algae take hold; once where it stays dry.
• Dumpster pads and trash enclosures — quarterly, monthly in summer.
• Building exteriors and siding — annually, or every two years in drier, lower-pollen locations.
• Parking garages and stairwells — annually, more where winter salt and grit get tracked through.

Wrong pressure is a repair bill, not a cleaning bill

Concrete and hardscape take high pressure. Siding, painted surfaces and older masonry need a soft wash with an appropriate detergent instead. A crew that uses one setting for every surface will eventually strip paint or etch concrete, and that damage costs more than several years of correct washing.

Argos does this as commercial pressure washing, scheduled overnight so walkways are dry before anyone arrives.

3. Moisture — the one that quietly gets expensive

The EPA's position on mold is refreshingly simple: "The key to mold control is moisture control." Their guidance is to dry water-damaged areas and materials within 24 to 48 hours, and to fix the water problem rather than just cleaning what you can see — otherwise it comes back (EPA, A Brief Guide to Mold, Moisture and Your Home).

For a property manager that translates into a short list of things that must not be allowed to sit:

• Gutters and downspouts — clear twice a year, spring and late fall. Add a third pass under heavy tree cover. Water backing up behind fascia is slow, invisible and costly.
• Grading and downspout discharge — water should run away from the foundation, not pool against it.
• Any reported leak — inside that 24 to 48 hour window, not next week.
• Breezeway and stairwell drainage — standing water is both a mold source and a slip hazard.

4. In-unit systems — small jobs, large consequences

Dryer vents are a fire-safety item

This is the one most communities under-schedule. The US Fire Administration is direct: "You are at higher risk of having a clothes dryer fire if you don't clean your lint filter and dryer vents." Their guidance includes checking behind the dryer for lint buildup, making sure the venting system is not damaged, crushed or restricted, and confirming the outdoor vent cover actually opens when the dryer runs (US Fire Administration, Clothes Dryer Fire Safety).

If you have in-unit laundry across a community, a rolling annual schedule is the standard approach — and it is worth documenting, because it is exactly the kind of thing that gets asked about after an incident.

HVAC filters

ENERGY STAR recommends checking the filter every month, especially in heavy-use winter and summer months, changing it immediately if it looks soiled, and at minimum every three months. Their reasoning is mechanical rather than cosmetic: a dirty filter slows airflow and makes the system work harder, wasting energy, and dust buildup leads to expensive repairs or early system failure (ENERGY STAR, Heat & Cool Efficiently).

Across a hundred units, a filter is a rounding error. A compressor is not.

Everything else on the punch list

• Loose handrails and wobbly balusters — a liability item, checked monthly
• Burnt-out breezeway and stairwell lighting — walked weekly after dark
• Door hardware, locks and closers that no longer latch cleanly
• Caulk and grout in wet areas, before it becomes a moisture problem
• Drywall damage and paint touch-up, especially ahead of a turn

Argos covers these as handyman services — usually by the crew already on your property, so there is no second vendor to schedule.

The schedule on one page

Intervals are a starting point. Tree cover, drainage, foot traffic and building age move all of them. We would rather walk your property and tell you which ones you can stretch than sell you a frequency you do not need.

Why one vendor beats five for this list

Look back at the table. Trash, breezeways, washing, filters, drywall, lights — those are traditionally five separate contracts, five onboarding packets, five invoices, and five people to call when something falls between them.

The practical failure mode is not that any one vendor is bad. It is that nobody owns the gaps. The trash company does not mention the burnt-out light. The landscaper does not flag the loose handrail. You find out from a resident.

A crew that walks your property every night sees all of it, and can tell you before it becomes a work order. That is the entire argument for consolidating — one contract, one invoice, one point of contact, and someone who notices.
