Introduction
Buying property in Nigeria should be exciting, not scary. Yet time and again, our Nigerian home inspection team uncovers hidden issues lurking behind freshly painted walls and shiny new fixtures. Whether you’re buying property in Lagos or house hunting in Abuja, the truth is clear: a home can look perfect on the surface and still hide costly problems. In Nigeria’s property market (new and old homes alike), what you don’t see can hurt you.
Why worry?
Consider that weak enforcement of building standards has allowed substandard practices and materials to flood the market
Unqualified builders often cut corners, ignore safety, and use low-grade materials. The result? Many homes – even brand-new ones – have defects that only a trained eye can catch. As one buyer put it after an inspection, “I’m grateful I didn’t skip the inspection. The last thing you want is to discover a major problem after the fact.”
The following are ten hidden problems our inspectors frequently find in Lagos, Abuja, and across the Nigerian property landscape. These examples show why buying property in Lagos or Abuja without a thorough inspection is a gamble you shouldn’t take.
1. Cracked Foundations and Structural Issues
Hairline cracks, sinking foundations, and weak structural supports are more common than you’d think. Developers may rush construction or use poor materials, leading to subtle cracks that are easy to paint over. Our Lagos inspectors often spot tiny fissures in foundation walls or pillars that signal bigger structural trouble. In one Lagos home, a “brand new” duplex had fine cracks snaking up the corners of rooms – a telltale sign of foundation settlement. Without an inspection, a buyer might only notice when those cracks widen after a few rainy seasons.
Structural issues are no small matter. Over a 20-year span, Lagos recorded 167 building collapse incidents, and more than 78% were residential buildings. While your prospective home isn’t literally falling down, even minor structural faults can worsen over time. In Abuja, for example, homes built on hilly terrain or filled land can develop cracks if the foundation wasn’t properly reinforced. An inspector will crawl into the substructure, check for uneven settling, and flag any structural red flags. As one Trustcrow inspection engineer says, By catching foundation issues early, you can avoid inheriting a building that might not stand the test of time.
“I always check the integrity of the foundation and beams – you’d be surprised how often a beautiful home is one heavy storm away from structural damage.”

2. Leaky Roofs and Ceiling Stains
That gorgeous roofline may not be so pretty when the rains come. Roof leaks are a hidden menace, especially in cities like Lagos with torrential rains. A house could be perfectly dry during your viewing (often in dry season) only to start dripping once the heavy downpours begin. Our inspectors routinely climb into attics and up on roofs in house inspections in Abuja and Lagos, and what they find isn’t always comforting: loose roofing sheets, cracked tiles, missing flashings, or gutter issues that cause water to seep in.
In Lagos, where annual rainfall exceeds 1,500mm, even luxury homes in Lekki or Ikeja have shown leakage signs if the roofing job was shoddy. We’ve seen freshly painted ceilings that hide brown water stains (someone clearly had a leak and tried to conceal it). Abuja homes are not immune either – an inspector in Abuja recently found that an upscale house in Maitama had several roofing nails improperly sealed. The telltale evidence was faint discoloration on a ceiling corner and a bit of mold starting to form. The buyer was shocked; the home was new, but a first heavy rain would likely have caused a damp ceiling or peeling paint.
Water damage can stay hidden until it wreaks havoc. A leak can lead to wood rot in the roof structure and nasty mold in ceiling panels. One study noted that water intrusion is a top cause of building defects globally – and Nigeria is no exception. It’s far cheaper to fix a minor leak discovered early than to repair a collapsed ceiling later on. So when our inspector reports mention things like “roof underlay improperly installed” or “stains indicative of past leakage,” pay attention. It could save you from sleeping with buckets on the bed during rainy season!
3. Poor Drainage and Flood Risk
Step into the compound – is it a future garden oasis or a hidden swamp? In many Lagos and Abuja properties, poor drainage is a serious hidden problem. The yard or surrounding land may look dry and solid most of the year, but heavy rains can quickly reveal if the property was properly graded and drained. Our Lagos inspectors often check if the compound has drainage channels, if water pools near the foundation, or if neighboring plots funnel runoff onto the property. You don’t want to wake up in a lake after a storm.
Lagos is notorious for flooding; blocked drainage and low-lying land can turn a dream home into a nightmare. In fact, Lagos’s ability to cope with flooding is severely hampered by poorly maintained drains. Thousands of residents are displaced by floods each year, and the city suffers an estimated $4 billion in flood damages annually We’ve inspected homes in Lekki and Ajah where the only thing standing between the living room and floodwater was a flimsy one-foot concrete barrier at the gate. Without proper drainage, heavy rain could send water cascading into the ground floor.
Abuja has its flood-prone spots too. Areas like Lokogoma and Lugbe have seen flash floods submerge homes when drainage was inadequate. One of our Abuja inspections revealed that an “alluring” new estate had no proper storm drains at all – the developers hadn’t accounted for the nearby river that swells in rainy season. A neighbor told our inspector that the previous year’s rain turned the access road into a flowing stream. These are insights you only get with local knowledge and thorough inspection. We run these checks so you’re not caught off guard. It’s far better to discover a potential flood issue before you buy – you can require the seller to improve drainage or you might decide the risk isn’t worth it. As the saying goes, buying property in Lagos without checking drainage is like driving in the rain without wipers. Don’t do it.
4. Electrical Hazards Behind the Walls
Many Nigerian homes harbor electrical problems that are invisible during a quick tour. Flick a switch and the lights come on – but what’s happening behind the scenes? Our inspectors often find wiring issues that range from dangerous DIY connections to outdated systems on the brink of failure. In older Lagos homes (think Surulere or Yaba), it’s not uncommon to find decades-old wiring with brittle insulation, or tangled “octopus” junctions not up to code. In Abuja’s newer estates, we’ve seen surprisingly poor electrical work too – sometimes the absence of proper earthing (grounding) or the use of substandard cables that overheat.
Electrical faults aren’t just a quirk; they’re a safety hazard. Nigeria’s Federal Fire Service identified electrical sparks as the number one cause of fire outbreaks nationwide in 2021. In that year alone, 636 fire incidents were caused by electrical sparks, far more than any other cause. This is a country where power fluctuations and generator use already put stress on electrical systems, so a poorly wired house is a ticking time bomb.
What kind of hidden issues do we find? Often it’s improper wiring connections – for example, in a Lekki apartment, our inspector discovered that many light fixtures were wired without junction boxes, just twisted wires wrapped in tape buried in the ceiling. In an Abuja house inspection, we found the AC units all tied to one undersized circuit, threatening constant breaker trips or overheated wires. And yes, lack of grounding is a recurring theme – one Ikoyi luxury home had metal appliances that gave off mild shocks because the electrician hadn’t connected the earth wires at all. Imagine a diaspora investor buying that home and finding out the hard way when they eventually visit!
The good news is our inspection report will detail these hazards. We test every outlet we can, we open up the electrical panel to see if it’s organized or a rat’s nest, and we verify safety devices like circuit breakers and RCDs. It’s much easier to ask a seller to fix an electrical issue (or negotiate the price down) when you have it documented. Bottom line: Don’t assume new means safe – always check the wiring. As one seasoned real estate broker says, blog.trustcrow360.com
“You don’t have to ask the seller to fix everything, but you do need to know what you’re getting into.”
5. Plumbing and Water System Failures
Water is life – until it’s leaking all over your new home. Plumbing issues are extremely common hidden problems in Nigerian homes, old and new. Unfortunately, many only become apparent after you move in, when that “small drip” turns into a big puddle. Our inspectors proactively check for leaky pipes, poor water pressure, and drainage problems in the plumbing system.
In Lagos especially, where many homes rely on boreholes and pump systems, a frequent hidden issue is low yield or dry boreholes. Imagine buying a house in Ikeja only to discover that the borehole doesn’t actually produce water in the dry season – a nightmare scenario that does happen. One Trustcrow client was eyeing a home in Ajah; everything looked great, but our inspector noticed the water taps had unusually weak flow. Further investigation showed the borehole was shallow and would likely run dry for months at a time. Thanks to the inspection, the buyer got the owner to drill a deeper borehole as part of the deal.
We also encounter sewer and septic issues. A hidden problem in many estates is poorly built septic tanks (soakaways) that leak or overflow. In Abuja, an inspection in Gwarimpa revealed that a soakaway was placed just 5 feet from the kitchen wall and had cracks – meaning sewage seepage could eventually undermine the foundation or, at the very least, produce horrible smells in the house. None of this was visible during a casual visit; only a trained inspector noticed the telltale depression in the ground and subtle odor outside.
Even inside the house, plumbing fixtures can hide problems. We test every faucet and toilet during inspections. It’s not rare that in a “brand new” Lagos duplex, half the bathroom faucets are either loose, leaking at the base, or the water heater isn’t heating. In older houses, pipes may be corroded. Nigeria doesn’t have lead pipes much, but rusted iron pipes can still contaminate water or burst under pressure. Statistics? It’s telling that only about 42% of people in urban areas have access to safe, treated water. Many houses depend on their own water systems – which vary wildly in quality.
Our job is to ensure the property’s water systems won’t leave you high and dry (or ankle-deep in water). From checking if the pump kicks in properly, to looking under sinks for moisture, to ensuring drains actually carry water out (and not, say, into a hidden pit under the house), we’ve got you covered. Don’t let a hidden leak turn into a flood of troubles after purchase.
Conclusion: Don’t Buy Blind – Inspect First!
Buying a home in Nigeria, whether in bustling Lagos or the quieter suburbs of Abuja, is a huge investment and a personal milestone. It’s exactly because it’s such a big deal that you want to ensure your dream home doesn’t turn into a nightmare after purchase. From structural cracks to leaky roofs, from hidden mold to termite feasts, we’ve highlighted 10 hidden problems that our inspectors frequently find. The common thread is simple: these are issues you’re unlikely to spot on your own, but a professional will. And once you know about them, you can either get them fixed, negotiate a better deal, or avoid a bad property altogether.
In Nigeria’s dynamic property market, a home inspection is your safety net. Think of it as an affordable insurance – a checkup that gives you peace of mind. Some sellers might not even know problems exist, and others… well, they might “forget” to mention them. Either way, a thorough inspection brings everything to light, so you’re buying with eyes wide open.
