Cheap blocks are often under-cured, made with too much sand and too little cement, or left porous. This makes them brittle and prone to cracking. Once cracks appear, water seeps in, leading to mould, damp walls, and in severe cases, structural weakening. Homeowners end up spending far more on plastering, repainting, or even partial rebuilding.
The Hidden Costs of Cheap Cement Blocks
At first glance, cement blocks may look like the cheapest way to build. They’re widely available in The Gambia, and the price per block is often lower than alternative building materials. However, what most homeowners and developers don’t realise is that the true cost of cheap cement blocks goes far beyond the initial purchase.
Repairs and Maintenance
Higher Paint and Plaster Costs
A porous block absorbs paint like a sponge. Instead of one coat, you might need three or four, plus primer. Over a decade, the cost of repainting every few years adds up to more than the original “savings” on cheap blocks.
Energy Inefficiency
Poorly made blocks don’t insulate well. Homes built with them get hotter in the dry season and cooler in the rainy season, leading to higher energy use for cooling or heating.

Practical Tip
Always check block quality before purchase. A good block should sound solid when tapped and should not crumble under pressure.
