A good safety net is built to last for years, but a little routine care goes a long way toward getting the full lifespan out of it. A simple visual check every few months is usually enough — look for loose or stretched sections, fraying at the edges, and any fittings that seem to be working loose from their anchor points.
Keeping the net reasonably clean also helps: dust, pollution residue, and bird droppings can accumulate over time, and a gentle rinse with water (avoiding harsh chemical cleaners) keeps the material in better condition without damaging the fibres.
If you do spot damage — a torn section, a loose anchor, or visible sagging — it's best to get it looked at rather than waiting, since small repairs are quick and inexpensive compared to a full replacement. Most issues can be fixed in a single visit if they're caught early.
