What to expect during fence installation: a step-by-step guide

If you have never had a fence professionally installed, the process can feel like a black box. You sign a contract, and then what? When do they show up? How long does it take? What do you need to do before they start? What happens if something goes wrong?

We get these questions all the time at Modern Fence & Deck. This guide walks through what a professional fence installation looks like from start to finish so you know exactly what to expect at each stage.

Before installation day

The work starts well before anyone picks up a tool. Here is what happens in the lead-up to your installation.

Site evaluation and quoting

Every project begins with a site visit. We walk the property with you, discuss your goals, measure the fence line, note terrain challenges, identify any existing structures or utilities, and talk through material options. This visit typically takes thirty minutes to an hour depending on the size and complexity of the project.

After the site visit, we prepare a detailed quote that covers materials, labor, permits, old fence removal if needed, and any site-specific work. The quote is itemized so you can see exactly what you are paying for.

Design and material selection

Once you accept the quote, we finalize the design details: fence style, height, color, post spacing, gate locations, and hardware. For aluminum fencing and steel fencing, this includes selecting the powder coat color and panel design. For composite fencing, we help you choose the board profile and color that work with your home.

Permitting

If your project requires a permit, we handle the application, plan preparation, and submission. Permit timelines in San Diego vary, but for straightforward residential fences, approval usually comes within a few days to a couple of weeks. We cover the permitting process in detail in our AB 3074 compliance guide.

Utility marking

Before any digging happens, we coordinate with 811 to have underground utilities marked on your property. This is a legal requirement and a critical safety step. Gas, water, electrical, and communication lines are all marked so we know exactly where they run.

Material ordering and fabrication

Depending on the material, there may be a lead time for manufacturing or fabrication. Custom steel and aluminum panels are fabricated to your specifications. Composite and hardwood materials are ordered from our suppliers. We schedule your installation date once all materials are confirmed and permits are in hand.

What to do before your crew arrives

There are a few things you can do to help the installation go smoothly:

• Clear the fence line. Remove furniture, planters, garden decorations, toys, and anything else within a few feet of where the fence will go. The crew needs a clear work zone.
• Trim vegetation. Cut back bushes, hedges, and branches that overhang or crowd the fence line. This saves time and prevents damage to your plants.
• Secure pets. Keep dogs and cats away from the work area for the duration of the installation. An open fence line and heavy equipment are not a safe combination for animals.
• Talk to your neighbors. Let your neighbors know the installation dates and approximate timeline, especially if the fence is on or near the property line. Good communication prevents misunderstandings.
• Verify access. Make sure the crew can access the work area. If the only path is through a locked gate or through your house, coordinate access in advance.

Installation day: what happens

Here is the typical sequence of a fence installation.

Old fence removal

If there is an existing fence to remove, this is the first task. Our crew removes the old fence sections, pulls posts, extracts concrete footings where necessary, and hauls away all debris. Depending on the length and condition of the old fence, removal can take a few hours to a full day. We offer fence removal as a standalone service as well.

Layout and marking

With the old fence out of the way, the crew lays out the new fence line. This involves setting string lines, marking post locations, and confirming gate positions. This is the step where the plan meets the ground, and any minor adjustments for terrain or obstacles are made.

Post installation

Posts are the foundation of your fence. The crew digs post holes to the appropriate depth, which depends on the fence height, material, and soil conditions. In San Diego, soil varies from sandy coastal fill to dense inland clay to rocky hillside, and the installation method adapts accordingly.

For most residential fences, posts are set in concrete. The concrete needs time to cure before panels are attached. Depending on conditions, the crew may set all posts on day one and return to hang panels the following day, or they may work in sections where cured posts get panels while fresh posts are still setting up ahead.

Panel and rail installation

Once posts are set and cured, the fence panels, rails, or boards are attached. The method depends on the material:

• Aluminum and steel panels are typically pre-fabricated and mounted to posts with brackets. Sections are leveled and secured.
• Composite fencing uses a rail-and-board system where horizontal rails are attached to posts and boards are slotted or fastened to the rails.
• Hardwood fencing involves attaching individual boards to rails with specialized fasteners, often requiring pre-drilling due to the wood’s density.

Gate installation

Gates are installed after the adjacent fence sections are in place. Gate posts carry more stress than line posts, so they receive deeper footings and heavier hardware. Single pedestrian gates, double-swing gates, and sliding gates each have their own installation requirements. We install custom gates with hardware rated for the gate’s weight and frequency of use.

Cleanup

At the end of each work day, the crew cleans up the site. Debris, packaging, and leftover materials are removed. We do not leave your property looking like a construction zone overnight.

Timeline: how long does fence installation take

The timeline depends on the scope of the project. Here are general ranges for San Diego residential fence installations:

• Small projects (under 100 linear feet, no removal): One to two days.
• Medium projects (100 to 200 linear feet, with removal): Two to four days.
• Large projects (200+ linear feet, complex terrain, custom gates): Four to seven days or more.

Weather, soil conditions, and permit timing can all affect the schedule. We communicate proactively if anything changes and keep you updated throughout the process.

Communication during the project

You should never feel in the dark about what is happening with your fence installation. Here is what we provide:

• Pre-installation confirmation. We confirm the start date, expected duration, and crew arrival time before work begins.
• Daily updates. For multi-day projects, we provide a brief update at the end of each day on what was completed and what is planned for the next day.
• Issue communication. If we encounter something unexpected, like hidden utilities, soil problems, or a property line discrepancy, we let you know immediately and discuss the options before proceeding.
• Direct contact. You have a direct line to your project manager throughout the installation. No phone trees, no voicemail loops.

Final walkthrough

When the installation is complete, we schedule a final walkthrough with you. During this walkthrough, we go over the entire fence line section by section. We check that panels are level, gates operate smoothly, hardware is secure, and the finished product matches the agreed design.

If there is anything that needs attention, we note it and address it before we consider the project complete. We do not ask for final payment until you are satisfied with the work.

This is also when we provide any maintenance guidance specific to your fence material. Different materials have different care requirements, and we want you to know how to keep your new fence looking its best for years to come.

After installation

Once your fence is in and the walkthrough is complete, there are a few things to keep in mind:

• Allow concrete to fully cure. If posts were set in concrete, avoid putting heavy stress on the fence (like leaning ladders against it or hanging heavy items) for at least 48 hours after installation.
• Check gate operation. Open and close your gates a few times in the first week to make sure everything is working properly. If a gate sticks or a latch needs adjustment, let us know.
• Begin your maintenance routine. Start the maintenance schedule appropriate for your fence material. We have a detailed fence maintenance guide by material that covers everything you need to know.

At Modern Fence & Deck, we believe the installation experience should be as good as the finished product. Our goal is a smooth, communicative process that respects your time, your property, and your investment.
