Planned vs Reactive Maintenance: Which Contract Model Is Right for Your Building?

One of the most fundamental decisions in building maintenance is whether to structure a contract around planned (preventive) work, reactive (on-demand) work, or a combination of both. The choice affects costs, building condition over time, and how predictable day-to-day operations feel.

This guide explains the difference between planned and reactive maintenance, compares their real costs, and looks at how to design a contract — often a hybrid — that fits your property.

What Is Planned (Preventive) Maintenance?

Planned maintenance refers to scheduled, recurring work carried out on a fixed calendar regardless of whether a specific problem has appeared. The goal is to keep building systems and spaces in good condition and catch small issues before they become bigger ones.

Typical planned maintenance activities include:

Daily tasks — emptying bins and replacing liners, cleaning desks and surfaces, vacuuming carpets and floors, cleaning entrances and corridors, disinfecting high-touch points, and sanitizing restrooms.

Weekly tasks — mopping hard floors, cleaning glass and windows, dusting furniture, cleaning meeting rooms, and removing fingerprints from doors and partitions.

Periodic tasks — deep carpet and upholstery cleaning, high-level dust removal, detailed floor maintenance, and cleaning behind furniture and equipment, alongside scheduled servicing of building systems such as HVAC filters, fire safety equipment, and lighting.

Because planned maintenance is scheduled in advance, it’s predictable to budget for and tends to extend the working life of building components.

What Is Reactive Maintenance?

Reactive maintenance (sometimes called “on-demand” or “corrective” maintenance) is work carried out in response to something that has already gone wrong — a broken fixture, a leak, a malfunctioning door, or an unscheduled spill that needs immediate attention.

Reactive maintenance is, by nature, unpredictable: it can’t be scheduled in advance, and the urgency varies widely — from a minor cosmetic issue that can wait a few days, to a safety hazard that needs an immediate response. A reactive-only approach means costs and disruption tend to spike unpredictably, often at inconvenient times.

The Real Cost Comparison: Planned vs Reactive

On the surface, reactive maintenance can look cheaper — you only pay when something needs doing. But the full cost picture usually tells a different story:

Planned maintenance has a predictable, budgetable cost, and tends to reduce the frequency and severity of breakdowns by catching wear and minor issues early. It also extends the lifespan of flooring, furniture, and building systems, deferring expensive replacements.
Reactive maintenance avoids paying for work that “isn’t needed yet,” but repairs are often more expensive when issues are caught late — a small leak that becomes water damage, or a filter that’s never changed leading to HVAC strain and higher energy costs. Reactive work also tends to come with urgency premiums and more disruption to occupants.

In practice, a building maintained purely reactively often ends up spending more over time than one on a planned program — the savings are an illusion created by deferring costs rather than avoiding them.

Which Model Suits Which Property Type?

The right balance between planned and reactive maintenance also depends on the type of property:

Offices with consistent daily occupancy benefit from a strong planned maintenance schedule covering daily cleaning and routine upkeep, with a reactive SLA for unexpected issues like equipment failures.
Retail and high-traffic commercial spaces need frequent planned cleaning due to heavy footfall, plus fast-response reactive cover for spills, breakages, or anything affecting the customer experience.
Multi-tenant buildings and common areas typically need a robust planned schedule for shared spaces, combined with reactive cover for tenant-reported issues across multiple units.
Seasonal or lower-occupancy properties may need a lighter planned schedule, with reactive maintenance covering most ad-hoc needs as occupancy fluctuates.

The Case for a Hybrid Approach: Planned + Reactive SLA

For most commercial properties, the most effective model combines both:

A planned maintenance schedule covering daily, weekly, and periodic tasks — keeping the building consistently clean, safe, and well-maintained.
A reactive SLA layered on top, with defined response times for unexpected issues — so when something does go wrong, there’s a clear process and timeline for resolving it.

This hybrid approach gives you the predictability and cost control of planned maintenance, with the flexibility to respond quickly when the unexpected happens — without paying premium rates for emergency call-outs on every issue.

What a Maintenance SLA Should Include in Switzerland

Whether planned, reactive, or hybrid, a clear SLA should specify:

The scope and frequency of planned tasks (daily, weekly, periodic).
The standards and methods used for each task.
Response time tiers for reactive requests, based on urgency.
How service quality is measured and reported.
What’s excluded from the contract, and how additional work is priced.
Any sustainability commitments, such as products used or waste handling.

Key Questions to Ask Before Signing a Maintenance Contract

Before committing to a planned, reactive, or hybrid contract, it’s worth asking:

What exactly is included in the planned schedule, and how often is each task performed?
What are the guaranteed response times for reactive requests, and do they vary by urgency level?
How is service quality tracked, and how often are reports provided?
What happens if a planned task is missed or a reactive request isn’t met within the agreed time?
Is the contract flexible enough to adjust the planned/reactive balance as needs change?

Conclusion

Planned and reactive maintenance aren’t mutually exclusive — the best contracts for most Swiss commercial properties combine a predictable planned schedule with a responsive reactive SLA for the unexpected. Understanding the real costs of each approach, and matching the model to your property type, helps ensure your building stays in good condition without surprises in cost or service.
