Can a wooden bench be left outside all year round?
A wooden bench is a timeless addition to any outdoor space. Whether it’s placed in a garden, on a porch, beside a fire pit, or along a pathway, wood brings warmth and natural beauty that other materials simply can’t match. But homeowners and DIYers often ask the same important question:
Can a wooden bench be left outside all year round?
The answer is yes—but only under the right conditions. Wood is a living, organic material that reacts to moisture, sunlight, temperature changes, and humidity. Without the right wood type, protective finish, and maintenance routine, even a well-built bench can deteriorate quickly.
In this expert-backed guide inspired by Ted’s Woodworking principles, you’ll learn which woods are best for year-round outdoor use, how to protect a wooden bench in every season, common mistakes to avoid, and how to dramatically extend its lifespan.

Why Outdoor Conditions Are Hard on Wood
Wood is strong, but it’s also porous and reactive. When left outdoors all year, it’s constantly exposed to:
- Rain and snow (moisture absorption)
- Sunlight (UV fading and drying)
- Heat and cold (expansion and contraction)
- Humidity changes (swelling and shrinking)
- Mold, mildew, and insects
Over time, these elements break down unprotected wood fibers and finishes. That’s why some wooden benches last decades outdoors while others fail in just a few seasons.
The Most Important Factor: Wood Type
The type of wood your bench is made from determines whether it can realistically stay outside year-round.
✅ Best Woods for Outdoor Wooden Benches
Teak
- Extremely weather-resistant
- High natural oil content repels water and insects
- Can last 30–50 years outdoors
- Premium price, premium durability
Cedar
- Naturally resistant to rot and insects
- Lightweight yet strong
- Excellent choice for DIY outdoor furniture
Redwood
- Performs well in damp climates
- Resists decay and warping
- Attractive natural color
White Oak
- Dense and water-resistant
- Stronger and more durable than red oak outdoors
👉 Expert Tip: Pressure-treated lumber is also suitable for outdoor benches but should be sealed properly and is best for functional rather than decorative seating.
❌ Woods That Should NOT Be Left Outside Year-Round
- Untreated pine
- MDF or particle board
- Indoor plywood
- Maple, birch, or beech
- Red oak (absorbs moisture easily)
These woods absorb water quickly and are prone to rot, cracking, and delamination outdoors.
Why Finish and Sealing Matter More Than You Think
Even the most durable wood will fail outdoors without proper protection. Finishing isn’t optional—it’s essential.
Best Finishes for Outdoor Wooden Benches
Spar Varnish
- Flexible finish that expands with wood
- Excellent UV resistance
- Ideal for sunny locations
Exterior Polyurethane
- Forms a hard protective barrier
- Best for covered or semi-covered benches
- Needs periodic reapplication
Penetrating Oil Finishes (Teak Oil, Tung Oil)
- Absorb into wood fibers
- Don’t peel or crack
- Require reapplication once or twice per year
Exterior Paint or Solid Stain
- Best UV and moisture protection
- Paint lasts longer than clear finishes
- Hides natural wood grain
👉 Pro Tip: Seal every surface, including the underside, legs, joints, and end grain.
So… Can a Wooden Bench Really Stay Outside All Year?
✔️ YES — If:
- It’s built from outdoor-rated wood
- All surfaces are sealed properly
- It’s positioned to avoid standing water
- It’s maintained regularly
❌ NO — If:
- It’s made from indoor wood
- It’s left unfinished or poorly sealed
- It sits directly on soil or grass
- It’s never maintained
A wooden bench outdoors isn’t “maintenance-free,” but it can be long-lasting.
How Climate Affects Outdoor Wooden Benches
Cold & Snowy Climates
- Freeze–thaw cycles cause cracking
- Snow traps moisture against wood
Solution: Elevate the bench and reseal annually.
Hot & Sunny Climates
- UV rays fade color and dry out wood
- Heat causes expansion and splitting
Solution: Use UV-resistant finishes and partial shade.
Humid or Rainy Regions
- High risk of mold and rot
Solution: Choose cedar, teak, or redwood and use penetrating oils.
Year-Round Maintenance Checklist
Think of maintenance like seasonal car care—it prevents expensive repairs later.
Spring
- Wash with mild soap and water
- Inspect for cracks or loose joints
- Reapply oil or sealer
Summer
- Monitor for fading or dryness
- Touch up finish as needed
Fall
- Reseal before cold or wet weather
- Tighten screws and joints
Winter
- Brush off snow regularly
- Avoid allowing ice buildup
- Keep bench elevated off wet surfaces
👉 Bonus Tip: Breathable furniture covers protect without trapping moisture.
Common Mistakes That Shorten Bench Lifespan
❌ Leaving wood unfinished
❌ Sealing only the top surface
❌ Using indoor wood outdoors
❌ Letting legs sit in standing water
❌ Ignoring peeling finish or cracks
Fixing small issues early prevents major damage later.
DIY vs Store-Bought Outdoor Wooden Benches
| Feature | Store-Bought ❌ | DIY Wooden Bench ✅ |
|---|---|---|
| Wood Quality | Often low | You choose premium wood |
| Joinery | Staples/screws | Strong reinforced joints |
| Repairability | Limited | Easy to fix or refinish |
| Longevity | 2–5 years | 10–30+ years |
| Customization | Minimal | Unlimited |
DIY benches last longer because they’re built with intention and care.
Should You Store a Wooden Bench During Winter?
If storage is available, it can help—but it’s not required.
Ideal Storage Options:
- Covered porch
- Shed with airflow
- Garage (not sealed airtight)
A properly built and sealed bench does not need to be stored, but storage extends lifespan.
FAQs: Wooden Benches Left Outside
1. Can untreated wood survive outdoors?
Only temporarily. Untreated wood will rot quickly.
2. How often should I reseal an outdoor bench?
Once a year for oil finishes; every 2–3 years for film finishes.
3. Is paint better than stain outdoors?
Paint offers more protection but hides the wood grain.
4. Will a wooden bench crack in winter?
Yes, if moisture enters and freezes—proper sealing prevents this.
5. What’s the longest-lasting outdoor wood?
Teak, followed by cedar and redwood.
