Fence Maintenance Guide (By Material)

A well-maintained fence lasts 2-3x longer than a neglected one. Here's what each fence type needs — and when it's time to replace instead of repair.

Wood Fence Maintenance

Wood fences need the most attention. Ignore them and they last 8-12 years. Maintain them and they last 20+.

Annual Checklist

• Inspect all posts for rot (push test — if it moves, it's compromised)
• Check for loose or warped pickets
• Look for leaning sections (post failure starts here)
• Clear vegetation touching the fence (holds moisture, accelerates rot)
• Check gates: hinges tight, latch working, no sagging
• Inspect the base: soil contact = rot. Ground should be 2-3 inches below the bottom rail.

Cleaning (Every 1-2 Years)

1. Power wash at 1,500-2,000 PSI (higher pressure damages wood grain)
2. Use a wood cleaner/brightener for gray or mildewed wood
3. Let dry completely (48-72 hours) before staining or sealing

Staining/Sealing (Every 2-3 Years)

• Cedar: Semi-transparent stain preserves the natural look. Apply every 2-3 years.
• Treated pine: Stain or paint within the first year (let it dry 3-6 months after install). Re-apply every 2-3 years.
• Redwood: Similar to cedar — semi-transparent stain every 2-3 years.

Cost: $2-5 per linear foot for professional staining. DIY saves 60% if you have a sprayer.

Common Repairs

Issue	Fix	Cost (DIY / Pro)
Rotted post	Replace post (dig, concrete, reattach rails)	$30-50 / $150-300 per post
Loose picket	Re-screw or replace individual board	$5-10 / $25-50
Leaning section	Reset post, add concrete, re-plumb	$40-60 / $200-400
Sagging gate	Replace hinges, add anti-sag kit	$20-40 / $75-150

When to Replace vs. Repair

• Replace if more than 30% of posts are rotted
• Replace if the fence is leaning in multiple sections
• Repair if it's isolated posts or pickets (patch-and-go)

Vinyl Fence Maintenance

Vinyl is the lowest-maintenance fence material. "Maintenance-free" isn't quite true, but it's close.

Annual Checklist

• Inspect for cracks (especially at connections and posts — cold weather damage)
• Check that panels are seated in the rails (wind can pop them out)
• Verify gates close and latch properly
• Look for mold/mildew (green or black spots) — more common in humid climates

Cleaning (Every 6-12 Months)

1. Garden hose for light dirt
2. Soft brush + mild soap (dish soap works) for tougher grime
3. For mold/mildew: 1/3 cup white vinegar per gallon of water. Spray, let sit 10 min, scrub, rinse.
4. Never use: bleach (can yellow white vinyl), abrasive cleaners, or power wash above 1,500 PSI

Common Repairs

Issue	Fix	Cost (DIY / Pro)
Cracked panel	Replace panel section (pop out, slide in new)	$30-80 / $100-250
Post cap missing	Snap on replacement	$5-15 / $25-50
Gate sag	Replace hinges, check post plumb	$20-40 / $100-200
Yellowing	Not fixable — UV damage. Prevent with UV-rated vinyl.	—

Lifespan: 25-30+ years with basic cleaning

Chain Link Fence Maintenance

Chain link is surprisingly durable but not indestructible.

Annual Checklist

• Check for rust spots (galvanized) or coating damage (vinyl-coated)
• Inspect tension wire and bands — loose = sagging fabric
• Verify tie wires are intact (fabric attached to top rail and posts)
• Check gate rollers/wheels if sliding gate
• Look for bent or crushed sections

Cleaning

• Hose down to remove dirt and debris
• For rust: wire brush the spot, apply rust converter, then spray paint with galvanized paint
• Vinyl-coated: mild soap and water

Common Repairs

Issue	Fix	Cost (DIY / Pro)
Small rust spot	Sand, prime, paint	$5-10 / $50-100
Sagging fabric	Re-tension using tension bar and come-along	$10-20 / $100-200
Bent top rail	Replace section (comes in 10.5ft lengths)	$15-25 / $100-200
Damaged fabric section	Patch with new mesh or replace full section	$20-50 / $150-300

Lifespan: 20-25 years (galvanized), 25-30 years (vinyl-coated)

Aluminum Fence Maintenance

Aluminum is truly low-maintenance — it doesn't rust, rot, or need painting.

Annual Checklist

• Check for loose pickets or rails (wind vibration loosens screws)
• Inspect powder coat for chips or scratches
• Verify gate self-closing mechanism works (spring tension)
• Look for impact damage (lawnmower strikes, fallen branches)

Cleaning

• Garden hose handles 90% of cleaning
• For stubborn spots: mild car wash soap and soft cloth
• Never use abrasive cleaners — they'll scratch the powder coat

Common Repairs

Issue	Fix	Cost (DIY / Pro)
Scratched powder coat	Touch-up paint from manufacturer	$10-20 / $50
Bent picket	Carefully bend back or replace section	$10-30 / $100-200
Loose screws	Tighten or replace with slightly larger screw	$0-5 / $50-100
Gate closer worn	Replace spring or hydraulic closer	$15-30 / $75-150

Lifespan: 30-50 years (the longest-lasting fence material)

Composite Fence Maintenance

Composite (wood fiber + plastic, like Trex) is the newest option. Very low maintenance.

Annual Checklist

• Inspect for surface mold (can occur in damp climates)
• Check that panels are secured — some systems use clips that can work loose
• Verify color is even (early-generation composites faded; modern ones resist UV)

Cleaning

• Power wash at 1,500 PSI or less
• Composite deck cleaner works on composite fencing too
• For mold: oxygen bleach solution (OxiClean), not chlorine bleach

Lifespan: 25-30 years (limited track record since it's newer)

Maintenance Schedule Summary

Material	Clean	Seal/Stain	Inspect	Expected Life
Wood (cedar)	Every 1-2 years	Every 2-3 years	Annually	15-20 years
Wood (treated)	Every 1-2 years	Every 2-3 years	Annually	10-15 years
Vinyl	Every 6-12 months	Never	Annually	25-30 years
Chain link	As needed	Never	Annually	20-30 years
Aluminum	As needed	Never	Annually	30-50 years
Composite	Every 1-2 years	Never	Annually	25-30 years

For Contractors: Maintenance as a Revenue Stream

Most fence contractors install and walk away. Smart ones offer:

• Annual inspection service ($75-150 per visit) — check posts, gates, fasteners
• Power washing + staining packages — $3-8 per linear foot, annual recurring revenue
• Post replacement program — customers call you first when a post rots, not a competitor
• Fence refresh service — power wash, stain, replace damaged boards — a $500-1,500 job that takes half a day

Maintenance keeps you in front of the customer. When they need a new fence in 15 years, they call you — not Google.

FenceCalc tracks customer records so you know who installed when — set reminders and sell maintenance services to your existing customer base.
