# Fence Installation & Repair: A Step-by-Step Guide for Arroyo Grande Homeowners
Spring on the Central Coast means assessing what the winter storms did to your property. In Arroyo Grande, I've spent the last few weeks looking at fences that took a beating — boards cracked from wind, posts loosened by our heavy clay soil, salt-air corrosion eating into metal hardware. If you're standing in your yard right now looking at a fence that's seen better days, or you're thinking about putting one in, I want to walk you through exactly how this works.
I'm Willy from Evolution Home Improvement, and I've been the guy fixing and building fences in Arroyo Grande and across San Luis Obispo County for years. This post covers the real process — the decisions you'll make, what materials matter, and when you should absolutely call a professional instead of DIY-ing it.
Step 1: Assess What You Actually Need
First thing: are you repairing an existing fence or starting from scratch?
For repairs: Walk the entire perimeter. Look for soft wood (push on posts with your hand — if your thumb sinks in, it's rotted), leaning sections, missing or split boards, and rusty hardware. Our salt-air marine layer up here on the coast accelerates corrosion, so metal fasteners and hinges degrade faster than they would inland. I had a customer on Cherry Avenue in Arroyo Grande last month who thought she just needed a few boards replaced. Turned out the entire west-facing side had dry rot in the posts from moisture trapped against our damp winters. That's a much bigger situation than swapping out one board.
For new installation: You need to know your property lines. This isn't optional. Call San Luis Obispo County or check your deed. The last thing you want is to build 40 feet of fence on your neighbor's land. Also find out if there are easements or utilities running through your property — PG&E, water lines, that kind of thing. One call to Dig Safe (811) marks them for free.
Step 2: Choose Your Material
You've got real options here. Willy's honest take:
Wood (pressure-treated or cedar): Classic look, blends with Arroyo Grande's landscape. Pressure-treated pine lasts longer in our damp climate than untreated wood. Cedar's more attractive but weaker in the posts. Both need sealing every 3-5 years if you want them to look decent. If you skip maintenance, you're accelerating the rot that'll make you replace the whole thing sooner.
Composite (wood-plastic blend): No painting, minimal maintenance. Holds up well to our coastal humidity. Material's lighter on your wallet than you'd think, but installation labor is basically the same.
Metal (aluminum or vinyl-coated steel): Corrosion-resistant, which matters here on the coast. Steel without coating will rust in our salt air. Aluminum won't, but it's softer. Both are low-maintenance.
Chain-link: Practical, visible, lowest maintenance. Not fancy, but it works.

Step 3: Understand the Ground Reality
Arroyo Grande's soil is heavy clay. This matters for posts.
You need to dig past the top 12 inches of soil — that's where our seasonal moisture sits. Posts need to go down 2-3 feet, or they'll heave up in winter and sink back down in summer, slowly working themselves loose. If you're near the coast (and Arroyo Grande's close enough), salt spray will corrode the post where it meets the ground. That's why concrete footings and proper drainage around the base are non-negotiable.
If you're setting posts yourself, a hand auger works for loose soil. Our clay? You might be reaching for a power auger real fast. This is one of those moments where renting equipment — or just calling someone who has it — saves you a day of frustration.
Step 4: Layout and Marking
Use string and stakes to mark your line. Measure twice. Mark post locations every 6 feet (standard for residential fencing). Check corners with a 3-4-5 triangle (measure 3 feet one way, 4 feet perpendicular, the diagonal should be 5 feet if your corner's square).
I usually mark posts with spray paint so I don't lose the spot when I'm digging. Sounds simple, but you'd be surprised how easy it is to get sidetracked and forget exactly where you need that next hole.
Step 5: Set the Posts
This is the foundation. Get this wrong and your fence will fail.
Dig holes 2-3 feet deep, 10-12 inches wide. Set the post in concrete — use a 50-pound bag of QUIKRETE per post mixed to manufacturer specs. Make sure posts are plumb (perfectly vertical) before the concrete hardens. Use a 2-foot level and brace the post with temporary supports. This takes 24 hours to cure properly. Don't rush it.
Willy's seen people try to set posts, let them cure for 2 hours, and start hanging boards. That concrete's still soft. Within a month the posts are shifting.
Step 6: Install Rails and Boards
Rails (horizontal support) typically sit 6 inches from the ground and 6 inches from the top for a standard 6-foot fence. Use 2x4 pressure-treated lumber for rails. Space pickets or boards consistently — that's what makes a fence look professional or look rushed. 1/8-inch gaps are typical, which also lets air flow (important for wood longevity).
Fasteners matter. Use galvanized or stainless-steel screws (not nails — they'll pop out). Nails loosen in wind and seasonal wood movement. Screws hold.
Step 7: Finishing and Maintenance
If you went with wood, seal it within a month of installation. Don't wait until fall. Summer UV and our dry season will start drying the wood out immediately, which leads to checking and cracking. One coat of sealer now means you're not replacing boards in 3 years.
For repairs, the same logic applies. A cracked board that's sealed will last. Unsealed, moisture gets in, wood rots, and suddenly you're replacing the whole section instead of just protecting the one board.
When to Call a Professional
Honestly, I'd recommend having Willy out for at least a consultation if:
Fences are one of those projects where the difference between "looks okay" and "looks good for years" comes down to how carefully the foundation was set and how good the materials are.
