Aluminum Shutters in Bilbao: Buying Guide and Maintenance Tips

In Bilbao, aluminum shutters aren’t a whim: between the humidity, the wind, and those “the sun comes out for five minutes” days, it pays to choose well. First: think about your routine. Are you a light sleeper and does any bit of brightness bother you? Then look for a shutter with tightly fitted slats and a shutter box that doesn’t let light leak in from the sides. Do you live on the first floor at street level? A friend of mine in Santutxu said adding anti-lift locking was life-changing: no more shutters “rattling” if someone tugs from outside. And watch the insulation: plain aluminum is tough, yes, but if you choose slats with a filled core (foam-type), you’ll notice less traffic noise and less cold clinging to the window in winter. By the way, ask whether your current shutter box will work or if it needs adapting: a lot of botched jobs come from forcing measurements, and then the shutter rubs, makes noise, and drives you crazy every time you raise it.

Maintenance in Bilbao is all about preventing humidity and dust from catching you out. The usual: it’s a Monday, you’re running late, you pull the strap and… crack, it stops halfway. To keep that from happening, every couple of months (or after a spell of windy rain) wipe the slats with a damp cloth and neutral soap and, above all, clean the side guides: that’s where grit builds up and ends up making the shutter scrape. If it’s motorised, don’t mess around with weird oils; the practical thing is to check there aren’t any leaves or dirt in the shutter box and that the travel is smooth. A handy at-home trick? Lower the shutter halfway and see if any slat is slightly twisted: if you catch it early, you can fix it before it catches and breaks. And if you hear a constant metallic squeak, that’s usually misalignment, not “just aluminium being aluminium”: better to adjust it in time than end up replacing parts.

With aluminum shutters, almost everything starts with “it just makes a little noise” and ends with “why didn’t I look at it sooner?”. If the strap is fraying, replace it now: it’s cheap and it saves you from ending up with the shutter stuck halfway down. If it’s a crank-operated one and you notice it turns with effort, it’s usually the winder or the shaft asking for a check-up; in that case, the sensible thing is to inspect the drum and the condition of the pulleys. With motorized ones, if it suddenly goes up in jerks, it could be a misadjusted limit switch or a tired motor: sometimes it just needs calibrating, other times it has to be replaced. When is it worth replacing? If you have dented slats in several spots (hail, impacts, or that balcony where the bike always gets leaned), it’s more worth your while to replace the entire curtain than to keep patching it. And if your shutter box is old and leaks air, that’s the big energy “theft”: investing in a better-sealed shutter box is noticeable in comfort, especially on cold, damp nights of a Bilbao winter.
