# Fence Installation & Repair: The Arroyo Grande Homeowner's Step-by-Step Guide
I've been installing and repairing fences in Arroyo Grande and across San Luis Obispo County for years now. In the dry months like these—July especially—more homeowners reach out about fence projects. Whether it's replacing a section damaged by the salt air blowing off the coast, or building out a new fence from scratch, I've learned what works and what doesn't in our climate. This guide walks you through the whole process, step by step.
Step 1: Assess What You Actually Need
Before you call anyone (even me), spend some time looking at your fence honestly. Is it a full replacement? A repair of one or two bad sections? Do you need a completely new fence where nothing exists?
I had a customer on East Branch Street last year who thought they needed a whole fence replaced. Turned out it was just three boards rotted by water pooling against the base. We fixed it in half a day, and they got years more life out of the fence. The lesson: know what you're looking at first.
Walk your property line. Look for soft spots in the wood (push on the posts and rails with your hand). Check for rust on metal fencing, leaning posts, or sections that have pulled away from the posts. The Central Coast salt air is rough on fencing—it accelerates rust and wood decay—so don't assume a fence that looks okay from the street is fine everywhere.
Take photos. Make notes about which sections are worst. This tells you whether you're looking at a repair or a bigger project.
Step 2: Check Property Lines and Local Permits
This matters more than most homeowners think. Before you build or replace a single fence board, know exactly where your property line is. Arroyo Grande and San Luis Obispo County require it—and I've seen disputes between neighbors turn ugly when someone built a fence two feet over the line.
Call the county assessor's office or get a property survey. It'll take a few days, but it's worth every bit of peace of mind. Once you know your line, you need to check whether your fence project requires a permit. Most fence installations in SLO County do—and honestly, the process isn't as painful as people think.
Willy (that's me) handles the permit stuff as part of the job for my customers. You *can* pull permits yourself, but if this is your first fence project, having someone who knows the local inspectors and the exact requirements takes a headache off your plate.
Step 3: Decide on Materials and Style
You've got options: wood, vinyl, metal, composite. Each has trade-offs.
Wood is traditional and looks good in Arroyo Grande's neighborhoods. Redwood or cedar resist rot better than pine, but nothing survives our salt-air climate without maintenance. I typically recommend painting or staining wood fences every 3–4 years if you want them to last.
Vinyl doesn't rot or rust, which makes it appealing on the Central Coast. It also doesn't need painting. But vinyl can get brittle in extreme sun, and if a board breaks, you're replacing the whole section, not just one board.
Metal (usually aluminum or steel) is durable but requires rust prevention in our coastal environment. Powder-coated aluminum holds up best to the salt air.
Composite is a mix of wood fiber and plastic—low maintenance, won't rot, but it can sag if not installed with proper support.
Talk to me about what makes sense for your specific location. If your property is within a mile or two of the coast, I'm probably recommending treated wood with good maintenance, or vinyl—the salt air changes the equation.
Step 4: Plan the Layout and Height
Measure your property line. Most residential fences in Arroyo Grande are 4 to 6 feet tall. Check your local HOA rules or city ordinances—some neighborhoods have height restrictions. Some require a certain setback from the street.
Draw it out, even roughly. Mark where the posts will go (typically every 6 or 8 feet). Note any slopes, obstacles, or drainage issues. The soil in parts of Arroyo Grande is clay-based and doesn't drain like sandy soil further inland. If water pools against your fence line in winter, you'll have rot problems fast—so think about grading or drainage while you're planning.
Step 5: Mark Post Locations and Dig
This is where the real work starts. Use string and stakes to mark your fence line. Mark post holes every 6 feet for most residential fences (closer if you're in a windy area—the coastal wind coming up from the dunes hits hard, and your fence needs to handle it).
Post holes need to go deep. Standard practice is 30 inches for a 4-foot fence, 36–48 inches for a 6-foot fence. Use a post hole digger or rent an auger if you've got a lot of holes. In our clay soil, a powered auger saves your back.
I dug 12 post holes by hand once in July. Once. Never again. Rent the equipment. It's worth not spending a weekend with blisters.
Step 6: Set the Posts in Concrete
This is non-negotiable. Posts that aren't set in concrete will shift, rot at the base, and fail. Use concrete mix—a 50-pound bag of QUIKRETE or similar will set one post solid.
Set your post plumb (perfectly vertical) using a level. Brace it with temporary 2x4s while the concrete cures. Check plumb from two directions—front-to-back and side-to-side. A post that's even a quarter-inch off will throw everything else out of whack.
Let concrete cure for 48 hours before you hang anything on those posts.
Step 7: Attach Rails and Panels
Once posts are set, attach the horizontal rails. Most fences use two rails (for a 4-foot fence) or three rails (for a 6-foot fence). Use 16-gauge stainless or galvanized fasteners—regular steel will rust, especially here on the coast, and your fence will get weeping rust stains and eventual structural problems.
I use 3-inch deck screws for most wood rail connections. They hold better than nails, don't pop out like nails do in our temperature swings, and they're easier to remove if you ever need to replace a section.
If you're doing boards (the vertical pieces), attach them to the rails with the same stainless fasteners. Space them according to your design—anywhere from no gap (privacy fence) to 1–2 inches apart (picket style).
Step 8: Seal or Paint (If Wood)
Don't skip this step. Bare wood in Arroyo Grande gets attacked by the elements. A good exterior stain or paint (with UV protection) keeps your fence looking good and prevents rot. Apply it within a week or two of installation, before the sun and salt air start breaking down the wood.
Re-seal every 3–4 years. It's way less work than replacing whole sections later.
Step 9: Inspect and Maintain
Once your fence is up, walk it every few months—especially after winter rains. Look for soft spots, loose fasteners, or sections that have shifted. Small problems caught early stay small. Wait until a board is completely rotted or a post is leaning and you're looking at much bigger work.
Trim back any vegetation that presses against the fence. Moisture trapped under leaves and branches accelerates rot.
Repair vs. Replacement: What Should You Do?
Sometimes you don't need a whole new fence. A few rotten boards? Replace them. A leaning post? Reset it. But if more than 20–30% of your fence is compromised—or if the posts are all shifting and unstable—replacement is the smarter move. Limping along with a half-broken fence is just delaying the inevitable, and it ends up being way more involved later.
I had a property on Huerta Avenue where the owner tried to patch and patch. Five years later, they called me back and the whole thing needed replacement. That's the kind of headache I try to help people avoid.
When to Call Willy
If you're handy and have done fence work before, some of this you can tackle yourself. But if you're not sure about permits, or you don't want to spend a weekend digging post holes in July heat, that's where I come in.
I handle the whole process: site assessment, permits, layout, installation, and finishing. I'm familiar with SLO County requirements, I know which materials hold up best to our coastal environment, and I stand behind the work. Most fence projects I take can start the same week, and I give free estimates—no obligation, no sales pitch.
