A little care goes a long way
A fence is out in the weather 365 days a year. Sun, rain, humidity, freezing nights, weed whackers, and the occasional soccer ball — it all adds up. The good news: most fence maintenance is simple, cheap, and takes an afternoon or two per year. The bad news: skip it, and a fence that should last 15 years might last 8.
Wood fences: stain and seal on schedule
Wood is the highest-maintenance common fence material, and it's also the one where maintenance matters most. In Maryland's humid climate, an unprotected wood fence will gray within a year, start checking and warping within a few, and rot at the ground line not long after.
Stain or seal every two to three years. A quality exterior wood stain with water repellent is the standard. Clean the fence first — a pressure washer on a low setting or a stiff brush and deck cleaner — let it dry fully, then apply stain on a dry day with no rain in the forecast. Two thin coats beat one thick coat.
Keep wood off the ground. Pickets and boards should not sit in soil or mulch. Moisture wicks up from the ground and rots wood from the bottom. If your fence was installed with boards touching dirt, pull the soil or mulch back a few inches along the fence line.
Keep sprinklers off the fence. Daily sprinkler spray is like a slow-motion pressure washer aimed at your fence. Adjust the heads so they water the grass, not the boards.
Replace damaged boards promptly. One rotted picket is a ten-minute fix. A rotted section left alone spreads the problem to the rails. Walk your fence once a year and swap out anything soft, cracked, or pulling loose.
Vinyl fences: wash and check
Vinyl is the low-maintenance champion. Once or twice a year, wash it with a garden hose, a soft brush, and mild soap. For mildew spots — common in shady, damp areas — a mix of water and white vinegar or a vinyl-safe cleaner does the job. Avoid harsh chemicals and abrasive pads, which can dull the finish.
After washing, walk the fence and check that posts are still plumb, caps are on, and panels are seated in their posts. Vinyl expands and contracts with temperature, so a panel that shifted slightly in summer heat usually just needs to be nudged back.
Chain link and aluminum: almost nothing
Galvanized chain link needs essentially no maintenance — just check that the bottom wire isn't buried in mulch and that ties are intact. Aluminum is similarly easy: wash it when it's dirty, touch up any scratches with manufacturer-approved paint to prevent corrosion at the bare spot, and check the screws and brackets yearly.
Gates: the moving parts need love
Gates are where fences fail first, because they move. Once a year: tighten the hinge screws, oil the hinges and latch, and check that the gate still swings level. A gate that drags on the ground will tear itself apart — adjust it before it gets bad. If your gate has a lock or an opener, follow the manufacturer's maintenance schedule. See our fence gates page.
Vegetation: your fence's quiet enemy
Vines look romantic growing on a fence, but they're slowly destroying it — they hold moisture against the material, add weight, and push boards apart. Keep vines, ivy, and heavy shrubs off the fence. Trim grass and weeds along the fence line so the string trimmer isn't chewing the bottom of your pickets every week. Leave a few inches of clearance between mulch beds and the fence.
The annual walk-around
Once a year — spring is ideal — walk the whole fence line slowly. Look for leaning posts, loose pickets, rust on hardware, gates that sag, and wood that's soft at the bottom. Push on a few posts; they shouldn't wobble. Catching a leaning post early is a small repair. Catching it after the section collapses is a rebuild.
