If you live in Ontario, you already understand how unpredictable and harsh winters can be. From heavy snowfall to freezing rain and fluctuating temperatures, outdoor conditions can quickly damage your patio setup. That’s why winterizing patio furniture is not just recommended; it’s necessary.
Whether you own a cozy backyard setup or a large patio, taking the right steps now can prevent costly replacements later. This guide by New Gill Furniture is designed to help homeowners protect their outdoor investment using simple, effective and expert-backed strategies.
Quick Answer: What to Store vs What Can Stay Outside
If you want a fast, practical rule:
Store Indoors (Always)
- Cushions & pillows
- Umbrella fabric
- Outdoor rugs
- Lightweight chairs
- Decorative items
Can Stay Outside (With Proper Protection)
- Aluminum frames
- Resin wicker furniture
- Heavy dining tables
- Some teak pieces
Expert Tip: Even “weather-resistant” furniture still needs prep. Leaving it exposed without cleaning or covering leads to long-term damage.
Complete Pre-Winter Checklist
Before the first snowfall, go through this:
- Clean all furniture surfaces
- Dry everything completely
- Remove cushions and fabrics
- Tighten screws and joints
- Drain water from frames or tables
- Choose proper covers
- Elevate furniture off the ground
- Store smaller items indoors
Think of this as your once-a-year reset for outdoor furniture.
What Does Winterizing Patio Furniture Mean?
Winterizing refers to preparing your outdoor furniture so it can either:
- Survive harsh winter conditions outdoors or
- Be safely stored indoors without damage
Main Goals of Winterizing:
- Prevent moisture damage and mould
- Avoid rust, cracking and fading
- Extend furniture lifespan
- Maintain appearance and comfort
How to Winterize Outdoor Furniture: Step-by-Step Guide
1: Deep Clean Before Storage
Cleaning Frames
Use mild soap and warm water. Avoid pressure washing; it can strip finishes or push water into joints.
Focus on:
- Armrests
- Undersides
- Table seams
Cleaning Cushions & Fabrics
- Brush off dirt first
- Use gentle soap and water
- Rinse lightly
- Air dry fully
Cleaning Wood & Teak
- Remove debris and stains
- Use a wood-safe cleaner
- Let it dry naturally
Real Insight: Leaves left on furniture over winter often leave permanent stains by spring.
2: Drying – The Most Overlooked Step
This is where most homeowners go wrong.
If moisture stays trapped:
- Mould forms
- Metal rusts
- Wood warps
- Cushions smell
Best Practice
- Dry furniture on a sunny or breezy day
- Stand cushions upright
- Leave space for airflow
If it feels even slightly damp, don’t store it yet.
3: Indoor Storage vs Outdoor Covering
Choosing between indoor storage and outdoor covering depends on space, material and how harsh your winter exposure is—especially in Oakville’s damp, freeze-thaw conditions.
Quick Decision Guide
| Situation | Best Choice | Why It Works |
|---|---|---|
| Cushions & fabrics | Indoor storage | Prevents mould, mildew and lingering odours |
| Small or foldable furniture | Indoor if possible | Easy to store and protects finishes from moisture |
| Large patio sets | Cover outdoors | More practical when storage space is limited |
| Teak & solid wood | Outdoor with airflow | Reduces risk of trapped moisture and surface damage |
If you’re unsure, use this simple rule:
- If it absorbs moisture → bring it inside
- If it’s heavy and weather-resistant → cover it properly outside
In real Oakville homes, most people use a hybrid approach:
- Store cushions and smaller items in the basement or garage
- Leave larger furniture outside with high-quality covers
4: How to Use Covers Properly
A cover only works if used correctly.
Do This
- Use breathable, fitted covers
- Secure them against wind
- Allow slight airflow
- Raise centre points (tenting)
Avoid This
- Wrapping tightly in plastic
- Covering damp furniture
- Letting water pool on top
Pro Tip: Add a small object (like a bucket) under covers to prevent water buildup.
5: Cushion & Fabric Storage Done Right
Cushions are the first thing to get damaged in winter.
Best Storage Options
- Basement shelves
- Indoor storage benches
- Dry garage cabinets
Avoid
- Plastic bags with no airflow
- Outdoor storage boxes (unless fully sealed and dry)
Real Experience: Even “waterproof” cushions can absorb moisture over time in freezing conditions.
6: Material-Specific Winter Protection
Not all patio furniture handles winter the same way. The right approach depends on how each material reacts to moisture, cold and temperature swings, especially in Oakville’s damp, freeze-thaw climate.
Aluminum
- Low maintenance and naturally rust-resistant
- Lightweight but durable
- Still needs cleaning and a well-fitted cover
Best Practice: Make sure water doesn’t collect inside hollow frames or joints before covering.
Steel & Iron
- Very strong, but highly prone to rust if exposed
- Vulnerable at joints, screws and chipped areas
Best Practice:
- Keep fully dry before storage
- Cover securely
- Touch up any chipped paint or coating before winter
Teak & Wood
- Naturally durable and moisture-resistant
- Can handle outdoor winter conditions better than most materials
Best Practice:
- Allow airflow don’t wrap tightly
- Keep surfaces clean and free from leaves
- If covering, ensure water can run off easily
Plastic & Resin
- Easy to clean and maintain
- Can become brittle in extreme cold temperatures
Best Practice:
- Store lightweight pieces indoors
- Avoid stacking in a way that adds pressure during freezing conditions
7: Elevate & Position Furniture Correctly
Never place furniture directly on concrete floors in winter.
Why
- Concrete holds moisture
- Cold transfers into materials
- Increases risk of rot and rust
Simple Fix
- Use wooden blocks or pallets
- Keep airflow underneath
8: Protect Umbrellas, Fire Tables & Accessories
Umbrellas
- Close and secure
- Remove fabric if possible
- Store indoors
Fire Tables
- Clean burner area
- Cover after cooling
- Keep moisture out
Accessories
- Store décor indoors
- Use sealed bins
These small items are often the first to get damaged and the easiest to protect.
Common Mistakes Oakville Homeowners Make
Even well-built patio furniture can get damaged if a few key steps are missed. In Oakville’s damp, freeze-thaw winters, small mistakes can turn into costly repairs by spring.
Avoid These Common Issues
- Covering furniture while it’s still damp
→ Traps moisture inside, leading to mould, mildew and rust - Leaving cushions and fabrics outdoors
→ Even “weather-resistant” fabrics absorb moisture over time - Ignoring furniture all winter
→ Small issues like condensation or snow buildup go unnoticed and worsen - Using non-breathable or poorly fitted covers
→ Causes moisture buildup instead of preventing it - Letting heavy snow sit for long periods
→ Adds stress to frames, joints and table surfaces - Placing furniture directly on garage or shed floors
→ Concrete holds moisture, increasing the risk of rust and rot
Biggest Mistake to Avoid
“Set it and forget it.”
Winter care isn’t a one-time task. Even properly covered or stored furniture should be checked periodically especially after heavy snow or temperature swings.
A quick mid-winter check can prevent:
- Trapped moisture issues
- Cover damage
- Structural strain from snow load
Expert Insight
From real homeowner experience in Oakville, the biggest problems don’t come from extreme cold, they come from neglected moisture and lack of airflow over time.
Stay proactive and your patio furniture will be ready to go the moment spring arrives.

Frequently Asked Questions About Winterizing Patio Furniture
1. Should I store patio furniture indoors for winter?
Yes, whenever possible. Indoor storage is the best option for items that can absorb moisture or get damaged by repeated freeze-thaw cycles. Cushions, pillows, umbrella fabric and lightweight furniture are usually better off in a dry garage, basement or storage area. For larger pieces that stay outside, proper cleaning, drying and covering are still important.
2. Can patio furniture stay outside during a Canadian winter?
Yes, some outdoor furniture can stay outside during winter, but only if it is prepared properly. Heavy aluminum frames, resin wicker and some teak furniture can often remain outdoors with the right protection. The key is to clean the furniture first, let it dry fully, use breathable covers and remove heavy snow buildup through the season. At New Gill Furniture, this is one of the most common questions homeowners ask when getting their patio ready for Ontario winters.
3. Are patio furniture covers enough to protect furniture in winter?
Covers help a lot, but they are not a complete solution on their own. A cover works best when the furniture underneath is already clean and dry and when the cover is breathable, secure and fitted properly. If moisture is trapped inside, the cover can actually make things worse. For the best results, many Oakville homeowners use a mix of indoor storage for soft items and outdoor covers for larger furniture.
4. How do I store outdoor furniture for winter if I do not have much space?
If space is limited, focus on storing the most vulnerable items first. Stack chairs, fold tables where possible, remove cushions and use vertical storage in a garage, shed or basement. Smaller accessories can go into labelled storage bins and cushions can be stored on shelves instead of the floor. Large furniture pieces can stay outside with good covers if indoor space is tight.
5. Can I leave patio cushions outside in a storage box all winter?
It is usually safer to store patio cushions indoors. Even when a deck box looks sealed, moisture can still build up inside over time, especially during damp Ontario winters. If cushions must go into a storage box, they should be fully dry first and the box should stay as dry and ventilated as possible. In most cases, indoor storage is still the better choice.
6. What is the best place to store patio cushions and outdoor fabric?
A dry indoor area is best. Basements, spare storage rooms, clean garage shelving and indoor benches all work well. The main goal is to keep fabric away from moisture, dirt and temperature swings. If you are unsure how to store outdoor soft goods properly, New Gill Furniture can help guide you toward practical solutions that suit real Oakville homes.
7. Should teak furniture be covered in winter?
Not always. Teak is naturally durable and handles outdoor exposure better than many other materials, but it still needs proper care. In some cases, leaving teak uncovered with good airflow is better than wrapping it too tightly and trapping moisture underneath. If you do cover teak, the cover should be breathable and shaped so water can run off easily.
