Many serious building problems begin as small, manageable faults. A dripping tap can damage a cabinet, a blocked gutter can cause ceiling leakage, and a loose electrical connection can damage equipment or create a safety risk.

Preventive maintenance means inspecting and servicing important parts of a property at planned intervals instead of waiting for emergencies. A structured calendar helps ensure that plumbing, electrical installations, drainage, roofing and safety equipment are not overlooked.

Tasks to Complete Every Month

Check for Plumbing Leakages

Inspect areas under sinks, around toilets, near water heaters and beside visible pipes. Look for dripping taps, damp cabinets, discoloured walls, unusual smells, slow drainage and water gathering around fittings.

Test Lights and Electrical Points

Check that lights, switches, sockets and essential appliances are operating normally. Call a qualified electrician if you notice burning smells, buzzing, sparks, hot sockets, frequent circuit trips, flickering lights or discoloured switches.

Inspect Doors, Locks and Windows

Ensure that doors close properly and that locks, hinges and handles are secure. Check window seals for gaps that may allow rainwater, dust or insects into the building.

Examine Walls and Ceilings

Take clear photographs and record the date so you can see whether a problem is spreading.

Check Drains

Inspect bathroom, kitchen and external drains for slow movement, unpleasant smells or standing water. Early cleaning can prevent complete blockages and flooding.

Review Cleaning Standards

For offices, apartments and commercial properties, inspect high-contact and frequently used areas. Confirm that waste is removed properly and that pests, odours and dirt are not accumulating in hidden spaces.

Tasks to Complete Every Three Months

Inspect the Roof and Rainwater System

A qualified professional should inspect accessible roofing components, gutters, downpipes and drainage outlets. Look for loose sheets, rust, cracked tiles, damaged flashing, blocked gutters, weak roof timber and openings around service pipes.

Service Air-Conditioning Units

Clean or replace filters where applicable and inspect drainage lines, electrical connections and cooling performance. Poorly maintained units may consume more energy, cool inefficiently or release water into walls and ceilings.

Inspect Water Tanks and Pumps

• Confirm that tank covers are secure.
• Check pipes, valves and joints for leakage.
• Listen for unusual pump sounds.
• Protect electrical connections from water.
• Ensure overflow water drains safely.
• Inspect the stability of supporting platforms.

Inspect Pest-Prone Areas

Check kitchens, stores, waste areas, ceiling spaces and external drainage points for signs of termites, rodents, cockroaches or other pests.

Review Fire and Safety Equipment

Inspect fire extinguishers, emergency lights, smoke alarms and exit routes where installed. Safety equipment should remain visible, accessible and within its approved servicing period.

Inspect External Walls and Surroundings

Look for cracks, damaged paint, algae, blocked drainage channels and areas where rainwater gathers close to the building.

Tasks to Complete Every Six Months

Service Generators and Backup Systems

Follow the manufacturer’s maintenance schedule for generators, inverters, batteries and other backup-power systems. Check fuel lines, filters, cables, ventilation and unusual sounds.

Inspect Plumbing and Water Pressure

A plumber should examine water pressure, concealed-leak indicators, valves and frequently used fixtures. Low pressure may point to a blockage, pump fault, damaged valve or leakage.

Deep-Clean Important Areas

Arrange deep cleaning for kitchens, bathrooms, drainage channels, storage rooms, service areas, air-conditioning vents and shared corridors.

Review Maintenance Records

Examine completed repairs, recurring complaints, equipment failures and emergency costs. Repeated repairs to the same component may mean replacement is more economical than continued patching.

Tasks to Complete Every Year

Conduct a Professional Building Inspection

Review the Electrical System

A qualified electrician should inspect the distribution board, protective devices, wiring condition, earthing and heavily loaded circuits.

Inspect and Maintain the Plumbing System

Arrange a detailed inspection of major pipes, valves, drainage lines, water pumps and sanitary fittings.

Repaint Where Necessary

External paint protects the building as well as improving appearance. Do not paint over moisture, loose plaster or structural cracks. Correct the underlying fault first.

Review Property Security

Assess external lighting, locks, gates, fencing, cameras, access controls and security procedures. Replace weak or outdated components before failure.

Prepare the Next Maintenance Budget

Separate planned work into emergency items, high-priority repairs, routine servicing, scheduled replacements and optional improvements.

Keep a Property Maintenance Record

Every property should have a simple maintenance log containing:

• Date of inspection
• Area or equipment inspected
• Problem identified
• Photographs or videos
• Recommended action
• Person assigned
• Cost estimate
• Completion date
• Invoice or receipt
• Next inspection date

Documented maintenance creates accountability and is especially useful for landlords, estate managers, companies and Nigerians managing properties from abroad.
