Cleaning: Water accumulates in joints – and limescale, dirt and unsightly discolouration quickly become visible. While these can be removed using everyday household products, cleaning can be very time consuming. Jointless surfaces are much easier to care for.
Hygiene: Joints are vulnerable to germs and bacteria. Microorganisms can accumulate in porous cement joints or behind gaps in silicone seals.
Durability: Joints that are not perfectly finished or that are showing the effects of time can start to come apart: Crumbling grout can potentially cause tiles to become unstable. Silicone seals can peel off, allowing water to infiltrate the gaps and wreak damage. In the worst-case scenario, defective seals will need to be removed and repaired. You will generally need to call in a professional for this – and costs can quickly mount up.
Health: Moisture can accumulate in joints and silicone seals – and this creates an ideal breeding ground for fungal spores. Mould is a health risk that should not be underestimated. It can spread all over the house and is difficult to remove.
