Deer fence installation is one of our Custom Fencing services, and it’s one where we’d rather lose a sale than sell you a fence that won’t actually do the job. Mule deer wander through Thornton yards and gardens more than most new residents expect, especially near open space and greenbelt areas, and the fence that actually stops them looks different from a standard backyard fence.

Why Thornton Homeowners Choose Us for Deer Fencing

We’ll tell you the real height a deer fence needs before we quote anything, even when that means recommending something taller and more expensive than you were expecting. A fence that looks right but doesn’t stop deer isn’t worth building.

Deer browsing tends to get worse in late fall and winter, when natural food sources dry up and a yard full of tender plants starts looking a lot more appealing. It’s worth planning installation before the season gets bad instead of after a garden’s already been picked clean.

Two Ways to Protect Your Property

7–8 ft

Full Perimeter

A fence around the entire yard needs to be roughly 7 to 8 feet tall to reliably keep deer out — they clear 6 feet without much trouble, and sloped ground toward the fence makes it even easier. Thornton requires a building permit above 7 feet, so this route means going through that process, but it’s the only way to get full protection for the whole property.

4–5 ft

Targeted Protection

If it’s really just the garden beds or a few specific plantings you’re trying to save, a shorter fence around just that area can work at 4 to 5 feet, since deer tend to avoid small, enclosed spaces even at a height they could easily jump. No permit required, and it solves the actual problem if the whole yard was never really the issue.

Most homeowners we talk to actually want the second option once they understand the tradeoff — an 8-foot fence around an entire property changes how the whole yard looks and feels, while a shorter enclosure around the vegetable garden or new landscaping solves the real problem without turning the backyard into something that feels fenced off from the neighborhood.

Material Options

Polypropylene Mesh

The most affordable option, and it blends into the landscape better than a solid fence. UV-resistant and holds up well outdoors, though it’s less of a physical barrier than metal fencing if something bigger tests it.

Welded Wire

Sturdier and more durable over the long run, with a more visible, structured look. Costs more than mesh but takes more abuse and lasts longer — worth it where deer pressure is heavy.

Installation Details That Actually Matter

Deer can push under a fence that doesn’t reach the ground or has gaps at the base, so we set the bottom edge tight to the grade, not just close to it. Posts go in deep enough to handle wind load on a tall fence, which matters more with mesh than solid materials since a large section of fabric catches a lot of wind. And we always plan human access into the design — a gate or walk-through point sized for wheelbarrows and equipment, not just a fence with no real way to get in and tend the garden it’s protecting.
