Winter fence maintenance protects your fence and deck from the elements, increasing their durability and longevity. Since our wet season spans November – March, mid-fall is the perfect time to observe these essential Bay Area fence and deck maintenance tips.
As always, Duce Construction Fence & Deck is here to perform professional inspections or to answer any questions you may have about your property’s fence or decks.
Rainy Season Preparation: October – March Timeline
While our rainy season spans November to March, the heaviest rains typically don’t start until December and January. Taking a little extra time to protect your fencing and decking investment can save you on unnecessary, costly repairs down the road.
In addition to being unsightly, all of these leave your property vulnerable and are much more expensive to repair or replace than the maintenance that would have prevented damage in the first place. Some of the most common damage caused by weather includes:
- Fence boards or panels that shear off or fall down during heavy winds.
- Cracking or splitting of wood.
- Rot.
- Rust.
- Mold/mildew.
⚠️ Costly Mistake to Avoid
Skipping fall maintenance can lead to emergency repairs mid-winter. Replacing rotted fence posts or deck boards during the rainy season costs 40-60% more than preventive maintenance due to weather delays and urgent scheduling.
The drier fall months offer the perfect opportunity to get a head start on essential winter fence maintenance steps. We’ve outlined a timeline, from November through March, to support DIY winter fence and deck maintenance and preparation.
November: Inspect & Clean Fences and Decks
While much of the attention on the winter storm season focuses on water damage, damaged fencing materials are particularly prone to wind damage. Performing a walkabout to look for specific signs of damage or warning signs is where you should start.
Here’s a general list of what to look for as you perform a DIY inspection of your decks and fences.
1. Stains or discoloration
Both wood and metal fences are installed with weatherproof coatings, each with its own lifespan. Some materials or weatherproof coats last longer than others—and none last forever. Also, deck or fence materials that are exposed to prolonged sun, wind, or rain are more vulnerable and require more attention.
Stains or discoloration indicate a chemical change in the materials, which can weaken or damage them. This could be mold/mildew, dryness leading to brittle wood fibers, rust, rot, pest damage, etc. Regardless of the cause, material repair or replacement is essential.
2. Loose or leaning posts
Look at and manipulate fence posts or deck railings to see if any are loose or leaning. These posts provide the bulk of the fence or railings’ structural stability. If they’re leaning or loose, it’s only a matter of time until attached portions begin to lean or collapse. This is a safety and security issue.
Take careful note of posts (and their footings) that are leaning, loose, or deteriorating in any way. This is especially important for deck supports or fence posts installed on a slope. These can be more prone to leaning or wiggling loose due to erosion over time.
3. Any signs of sagging or warping
Fluctuations in temperature and humidity cause wood and other materials to expand and contract. Over time, and without property protection, this can lead to sagging or warping. When parts start to change shape, dimension, or alignment, they no longer work together as designed, putting strain on the adjacent materials, which can cause further damage.
These pieces or parts should be replaced whenever possible. If sections of fence or deck are sagging or warping due to their lack of quality, we may recommend replacing the fence or deck altogether, as it’s only a matter of time before you have to replace other portions or sections of the structure.
4. Cracking or splintering
Dry wood cracks and splinters. This leaves interior layers of the wood further exposed to the elements. If the cracking or splintering is just starting, affecting the surface layers, sanding and outdoor-quality fillers and adhesives may be enough to repair them so they can be primed and restrained or painted. If the cracking or splintering has progressed to the point that it extends beyond the surface, professional repair or replacement is recommended.
5. Checking along the groundline
The earth is a consistent source of moisture and damp, particularly after irrigating or a rain. Part of rainy season preparation entails walking the ground line of your fences and decks, paying particularly close attention for any signs of rot or discoloration. We recommend leaving a clearance of at least two inches between the ground and your fence or deck materials to minimize moisture contact. Keeping up with your landscape maintenance —trimming lawns, hedges, and undergrowth —can also help to minimize direct contact.
⭐ Key Maintenance Rule
Maintain at least 2 inches of clearance between the ground and your fence or deck materials. This simple gap dramatically reduces moisture contact and can extend the life of your structure by 5-10 years.
6. Eroding protective coatings, finishes, or paint
We’ve mentioned that weather-resistant finishes can wear away or erode over time. Any peeling, cracking, bubbling, or missing patches leave the fence or deck materials vulnerable. Now’s the time to patch or strip and refinish fences and decks so they’re fully protected from wind and rain.
7. Rusted, damaged, or loose hardware
As long as you’re performing a winter fence maintenance inspection, perform a visual inspection of the hardware used to attach and reinforce the structures. Be on the lookout for any signs of rust. In some cases, rust can be sanded off and the part can be repainted, sealed, or finished using a materials-specific protectant. If the rust is so thick that it’s altered the part’s shape or function, it should be replaced. Also test for any loose parts, as well as any nails or screws that are easing their way out and need to be tightened.
NOTE: If your fence straddles the boundary between your property and a neighbor’s, rainy season preparation can be a joint effort. Many hands make light work, so cooperating with neighbors can make the entire process swifter and easier. You may also enjoy the benefits of sharing tools and pooled DIY expertise.
Time to clean things up
Once you’ve completed your inspection and made all necessary repairs or replacements, it’s time to clean up.
- Trim any overhanging trees or overgrown shrubs.
- Remove branches, twigs, leaves, and other debris that have accumulated on the deck’s surfaces. Over time, these harbor pests and also retain moisture that leads to rot.
- Keep all gutters, downspouts, and property drainage systems clear of debris. You may need to flush them out to prevent blocked-up water or water overflows that expose fencing and decking materials to excessive moisture.
These proactive steps minimize the risk of moisture or structural damage, preventing unnecessary repairs or replacements.
December – February: Keep an Eye on Things & Perform Post-Storm Maintenance
December through February are the wettest months for most Bay Area residents. Your pre-winter fence maintenance should set you up to weather the storm. However, some storms are worse than others, so always perform post-storm walkabouts to keep an eye on things.
On dry days in between storms, we recommend that you or your landscape crew pay careful attention to any accumulated debris on the decks, fallen limbs/branches on the fence line, or damaged trees that pose a threat to your property’s structures.
March: Post Winter Recovery & Fence Repair
As we head into spring, your fence and decks may be in need of repairs that go beyond your DIY know-how. Make sure you enlist help from a licensed fence contractor to ensure your repairs are done as per building code and using the highest-quality materials. This work is not something you want to trust to a “handyman,” because it may void relevant product warranties.
During your own or a professional’s fence inspection, you may find that an older fence has finally had enough. When repair costs reach or exceed 50% of the cost of a new fence or deck, or when your repairs over the last few years are adding up, we typically recommend replacing them.
ℹ️ The 50% Replacement Rule
Industry professionals use a simple rule: when repair costs reach or exceed 50% of new fence or deck installation costs, replacement becomes the smarter investment. This typically happens with structures 15-20 years old.
