Maintain vs Maintenance: Understanding the Difference

One reason people write maintenanced is that they confuse maintain with maintenance.

Here’s how they differ:

Notice that maintenance refers to the activity itself, while maintained describes an action that has already happened.

Why Do People Say “Maintenanced”?

The confusion behind maintained vs maintenanced usually comes from workplace language.

1. Industry Jargon

In some technical environments, employees use maintenanced informally as shorthand for:

• Serviced
• Repaired
• Maintained

Although coworkers may understand it, the term isn’t part of standard grammar.

2. Turning Nouns Into Verbs

English sometimes allows nouns to become verbs.

For example:

• Email → Emailed
• Google → Googled
• Text → Texted

Some speakers mistakenly assume:

Maintenance → Maintenanced

However, standard English already has the verb maintain, so creating maintenanced is unnecessary.

3. Workplace Habits

Certain companies adopt internal terminology that spreads among employees.

While common inside an organization, that doesn’t necessarily make the term grammatically correct in general English.

Examples of Correct Usage

Here are examples using maintained correctly.

Correct

• The road has been well maintained.
• Our computers are regularly maintained.
• The garden was carefully maintained throughout the year.
• Engineers maintained the equipment according to schedule.
• The aircraft was properly maintained before departure.

Incorrect (Standard English)

• The road was maintenanced.
• The computers were maintenanced yesterday.
• The building has been maintenanced.

In formal writing, replace maintenanced with maintained.

• Landscaping
• Software support
• Infrastructure management

Examples:

• Our website is maintained by an experienced developer.

When Should You Use “Maintenance”?

Remember:

Maintenance is a noun.
