Planned maintenance saves money because small defects are cheap to fix and expensive to ignore. A blocked gutter cleared in ten minutes prevents a ceiling collapse; a cracked sealant joint replaced for a few thousand shillings prevents damp that ruins a wall. For offices, schools, banks and clinics in Tanzania, a simple plan with scheduled inspections, a defects log and a yearly budget of roughly 1 to 2 percent of the building's replacement value keeps the building safe, keeps running costs down and avoids the large emergency repairs that disrupt work.
Reactive or planned maintenance?
| Approach | How it works | Result |
|---|---|---|
| Reactive | Fix things when they break | Higher costs, disruption, safety risks |
| Planned (preventive) | Inspect and service on a schedule | Lower long-term cost, fewer surprises |
| Condition-based | Act when inspections show wear | Efficient, but needs good records |
Most organisations here run on reactive maintenance. Switching even part of the budget to planned work makes a visible difference within a year or two.
What to inspect and how often
Roof and rainwater
- Clear gutters and downpipes before each rainy season, and after heavy storms.
- Check iron sheets for loose screws, rust and lifted laps.
- Check flat roofs for ponding and cracked waterproofing.
- Clear roof outlets on concrete slabs.
Our roof leak repair guide explains common faults.
Walls and structure
- Look for new cracks, damp patches and spalling concrete every six months.
- Repaint exposed walls every five to eight years, sooner near the coast.
- Check sealant around windows and joints.

Plumbing and drainage
- Check tanks, pumps and pressure sets monthly.
- Clean water tanks every six to twelve months.
- Empty septic tanks on schedule. See septic tank design.
- Clear stormwater drains before the rains.
- Fix dripping taps and running toilets straight away. They waste a lot of water.
Electrical and mechanical
- Service air conditioners every three to six months.
- Test the generator weekly and service it on hours run.
- Have an electrician inspect boards, earthing and wiring yearly.
- Test lightning protection and earthing. See our lightning protection guide.
- Service lifts according to the maker's schedule.
Fire and safety
- Service fire extinguishers yearly.
- Test alarms and emergency lights monthly.
- Keep escape routes clear.
Finishes and fittings
- Replace broken tiles and loose skirting quickly.
- Oil hinges and locks.
- Repair ceiling boards with water stains, and find the leak first.
A simple maintenance calendar
| Frequency | Tasks |
|---|---|
| Weekly | Generator test, walk-round of common areas |
| Monthly | Pumps and tanks, fire alarms, emergency lighting |
| Quarterly | Air conditioner service, drains, roof walk |
| Before each rainy season | Gutters, downpipes, roof outlets, stormwater drains |
| Yearly | Electrical inspection, fire extinguishers, tank cleaning, full building survey |
| Every 5 to 8 years | External repainting, roof sheet or waterproofing review |
Our home maintenance calendar uses the same idea for houses.

How much should you budget?
A common guide is 1 to 2 percent of the building's replacement cost each year, more for older buildings or those near the coast. Set aside a separate sum for big items that come every few years: repainting, roof replacement, air conditioning units. Spreading these costs avoids sudden large bills.
Keep records
- A defects log with photos, dates, who reported and when it was fixed.
- As-built drawings and equipment manuals from handover. See construction handover documents.
- Service records for generators, lifts, air conditioners and fire equipment.
Good records also help when you plan a renovation or sell the building.
In-house team or contractor?
Small organisations often use a caretaker for daily tasks and specialist contractors for services. Larger ones combine an in-house team with a maintenance contract. Whatever the setup, make one person responsible for the plan.
Maintenance by building type
Each kind of building has its own weak points.
- Schools: doors, windows, desks, taps and toilets take hard daily use. Check toilet blocks and water supply every week during term, and do bigger repairs in the long holidays. Gutters and drains need clearing before each rainy season, because many school compounds flood.
- Banks: security systems, strongroom doors, ATMs, air conditioning and backup power cannot fail. Service them on a strict schedule, and plan any works outside banking hours. See our bank branch construction guide.
- Clinics and health centres: water, power for fridges and lights, handwashing basins and medical waste areas come first. Finishes must stay washable, so repair cracked tiles and peeling paint quickly.
- Offices: air conditioning, lifts, toilets and lighting drive most complaints. Regular servicing is cheaper than emergency call-outs.
Coastal buildings need more
Salt air near the coast rusts iron sheets, steel windows, railings and reinforcement much faster than inland. Wash down exposed metal, repaint more often, and check concrete for rust stains every year. Our guide on building near the coast explains the materials that last longest.
Frequently asked questions
How much does building maintenance cost per year?
As a guide, 1 to 2 percent of replacement cost per year, higher for older buildings or harsh coastal locations.
What is the most common maintenance failure?
Blocked gutters and drains. They cause leaks, damp and flooding, and they are the cheapest thing to fix.
When should I get a structural engineer?
When you see new or widening cracks, sagging slabs, exposed rusting steel, or after major damage. See signs a building needs a structural inspection.
Does planned maintenance really save money?
Yes. Small defects grow. Water damage in particular spreads into ceilings, walls, wiring and floors if left alone.
Who should be responsible for maintenance?
One named person, such as a facility manager, administrator or caretaker, with a budget and the authority to call contractors. When nobody owns it, nothing happens.
Is a maintenance contract worth it?
For generators, lifts, air conditioning and fire systems, yes. Specialists service them on schedule and respond faster to breakdowns.
How often should a building be repainted?
External walls every five to eight years inland, sooner near the coast. Internal walls in busy areas may need it every three to five years.
