8 ways to winterize a balcony and weather-proof yours like a pro, leaving it intact, ready and raring to go in spring
Expert advice to ensure your balcony is ready for the cold season
Winterizing your balcony protects it from cold weather damage and ensures that when it finally warms up and you want to use it more, it's ready to go.
From protecting your furniture to resealing grout, follow our home experts' eight simple steps to keep your balcony in top shape during the colder months.
When it comes to winterizing a house, it makes sense to start from the most vulnerable spot, open to the elements – your balcony.
Step 1: Protect outdoor furniture
Cold temperatures and moisture can damage outdoor furniture, so it's best to get it protected before the big freeze.
Jon Christensen, CEO of home improvement hub Bidmii, says, 'Ahead of winter, covering your balcony furniture with weather-resistant materials can extend its lifespan by shielding it from snow, rain, and freezing temperatures.
'To do this, first clean your outdoor furniture to remove any dirt or debris that could lead to mold or mildew. Once it's dry, cover each piece with a durable, waterproof cover that fits securely. I recommend the Duck Covers Ultimate Patio Furniture Covers from Classic Accessories. They're made of heavy-duty material that resists tearing and have secure tie-downs to keep the covers in place during windy conditions.'
Ben Soreff, professional organizer at House to Home Organizing, adds, 'Another option is to group all your balcony furniture under an all-in-one cover, such as this ULTCOVER Rectangular Heavy Duty Cover from Amazon.'

Step 2: Insulate water fixtures
If you have outdoor faucets or water features, insulate them to prevent freezing and cracking.
Christensen says, 'As winter approaches, it's worth taking the time to prepare any taps, hoses or pipes so they won't freeze or burst.
'Begin by shutting off the water supply to outdoor faucets from inside your home. Then, open the outdoor tap to let any remaining water drain out. This ensure there is no water remaining which could freeze over the winter.
'Finally, insulate faucets with foam covers designed for outdoor use. This Thermwell Frost King Plastic Faucet Cover from Amazon is an affordable option that provides effective insulation against freezing temperatures.'
Step 3: Install gutter guards
If your balcony has gutters, install guards to keep out leaves and debris.
Karina Toner, operations manager of Spekless Cleaning, says, 'Gutter guards prevent leaves and debris from clogging gutters, which can lead to ice damming and water buildup during winter.
'To install, clean out the gutters first, removing any leaves or dirt, then install gutter guards according to package instructions.'
Toner recommends the Gutter Guard Brush by Gutterglove, the FlexxPoint FlowGuard Premium 50-Year Gutter Cover System, and the Raptor Gutter Guard – all of which are available on Amazon.

Step 4: Store moveable items
Windy winter weather can easily knock over lightweight items, like planters or decorations.
Christensen says, 'Store any movable items like planters, rugs, or decorative pieces that could be damaged by winter weather. Strong winds and heavy snowfall can turn these objects into hazards or cause them to deteriorate.
'If you have potted plants that are sensitive to the cold, consider bringing them indoors as well, or wrapping them with insulating materials to protect their roots.'

Lanterns and portable heaters are two other common balcony items that would be better relocated inside for the winter when not in use, should you have the space, but make sure to follow safety precautions and never run indoors
Step 5: Reseal grout
The grout between tiles on your balcony can crack and wear down over time. Before winter hits, reseal the grout to prevent water from seeping in, freezing, and expanding, which can lead to costly cracks and structural damage.
Steve Evans, owner of Memphis Maids, says, 'Before winter hits, it's vital to reseal your grout to avoid water or moisture seeping into the floors or walls. I like this Miracle Sealants 511 Impregnator Sealer from Walmart because it works for tile and grout, so you can seal the entire surface at once. You also have epoxy-based LATICRETE SPECTRALOCK Pre-Mixed Grout from Amazon, which doesn’t need any sealing.'
Watch out for these grouting mistakes the pros always notice, however.
Step 6: Remove mold and mildew
Mold and mildew thrive in wet, cold conditions – so it's a great idea to ensure your balcony is mold-free both before and after.
Evans says, 'During the winter, there’s a higher chance you see mold and mildew growing on your balcony. I’ve found this CLR Mold and Mildew Remover from Amazon has always worked for me, as it's compatible with many different surfaces – plus, it’s bleach-free, so it won’t stain any fabrics you have nearby.
Keeping your balcony clean will help prevent mold from worsening over winter. Algae has a particular habit of accumulating on decking, so if this is a feature of your balcony flooring, treat it with one of five slippery deck solutions.
Step 7: Secure hanging items
If you have hanging plants, lights, or decorations, make sure they’re securely fastened or remove them altogether.
Francisco Fuenmayor, a home improvement expert at LocalProBook, says, 'High winter winds and snow can turn hanging items like bird feeders or decorations into hazards. Therefore, I always advise taking down all hanging items and either removing them from the balcony completely, or securing them tightly to prevent damage.'
Fuenmayor recommends using heavy-duty bungee cords such as Amazon’s Cartman Bungee Cord Assortment, which are durable and weather-resistant. He adds, 'This handy set consists of 32 pieces, including various lengths and colors. Made from high-quality rubber, these cords are designed to withstand all types of weather conditions, including freezing temperatures.'
Put your feeder away for the winter once the hummingbird migration of these gorgeous little birds is done. This particular one holds 16 oz of liquid feed, has a bee guard and built-in ant moat to keep pests out of your winged friends's food source.
Step 8: Store away rugs
Even the best outdoor rugs are susceptible to mold and mildew in damp conditions.
Fuenmayor explains, 'Leaving rugs out in winter can lead to mold and material breakdown. For best protection, roll up any outdoor balcony rugs and store them indoors, or in a waterproof bag.
'If you must keep them out, go for a weather-resistant storage box, like the Keter Westwood 150-Gallon Resin Box from Walmart, which comes in two color options – dark gray or espresso brown. Its design is ideal for protecting items from moisture and will keep your rug looking fresh for next season.'
So there you have it – how to winterize a balcony in eight ways. Winterizing your balcony will help protect it against the cold and ensure everything is in good shape when warmer weather returns.
