Sakrete Fence Installation: The Orlando Owner’s Guide
If you’ve got Sakrete bags sitting in the garage and a fence project waiting, here’s what you need to know: a professionally installed fence in Orlando using Sakrete fast-setting concrete for the posts typically runs $3,500 to $9,000, and we can usually have it done in two to three days once materials are on site. Most homeowners call us after the first post starts leaning, or after a Florida afternoon storm reveals that the original concrete mix wasn’t right for our soil.
Sakrete makes a fast-setting concrete mix that works well for fence posts in Central Florida, but the product itself isn’t a “fence system.” It’s the anchor. And in Orlando, the anchor is where fence projects either succeed or fail, because our sandy soil and the freeze-thaw cycle that doesn’t really apply here are replaced by a different problem: saturation and shifting. When posts are set shallow or the mix isn’t allowed to cure properly before backfilling, you get a fence that leans within a year.
We’re an independent Orlando contractor, not affiliated with Sakrete. But we work with their fast-setting mixes on fence projects every month, and we know exactly how this material behaves in local soil conditions.
Which Sakrete Models This Applies To
Sakrete manufactures several concrete products that apply to fence installation, and the compatibility question depends on which one you’re holding. The most common for fence posts is Sakrete Fast-Setting Concrete Mix, the red bag. It’s designed to set in about 20 to 40 minutes without mixing: you pour it dry into the hole, add water, and it hardens around the post. For heavier posts or gates, Sakrete High-Strength Concrete Mix is the stronger choice, but it requires mixing and a longer cure time before you can attach rails or panels.
The compatibility gotcha in Orlando: fast-setting mix is designed for a minimum 40°F application temperature. In our climate, that’s fine, but the catch is that fast-setting also means fast decisions: you’ve got roughly 20 to 40 minutes before it’s too firm to adjust the post. If you’re setting posts in a straight line down the side of a yard in College Park and a thunderstorm rolls through mid-job, you lose your adjustment window. We’ve had to drill out and reset posts because a homeowner started the project in June and the afternoon rains moved the clock.
The other spec that matters is post hole diameter. Sakrete specifies a hole three times the post width for fast-setting mix. For a standard 4×4 post, that’s a 12-inch hole, at least 24 inches deep in Central Florida to get below the seasonal moisture line. We see a lot of fences in Orlando that were set at 18 inches, with 60-pound bags split across two posts to save money. Those are the fences we get called out to fix in August, after the ground has been saturated for six weeks and the posts shift.
One more note: don’t use Sakrete mortar mix for fence posts. Mortar is for masonry joints, not structural anchoring. We’ve seen it happen, and the post pulls free clean, like it was set in a candle.

Signs Your Sakrete Fence Installation Is Failing
- The post leans but the pickets are still straight. This means the post has shifted underground, usually because it was set too shallow or the concrete was under-mixed. The post moves; the fence doesn’t. It’s an anchor problem, not a fence problem.
- You see a donut of cracked concrete at the base of the post. Water gets into the gap between concrete and wood, and the swelling and drying cycle cracks the top layer of the set concrete. Once the donut cracks, water goes deeper, and the cycle accelerates.
- The gate drags on the ground four months after installation. Gate posts take double the load of line posts. If the gate post was set with fast-setting mix but the hole wasn’t wide enough or deep enough, the entire post flexes, and a gate that clears in January drags by May.
- You can rock the post by hand. Grab the post at the top and push. Any movement that isn’t the entire fence moving means the concrete bond has failed or the post is rotting below grade. In Orlando, this is often a moisture problem: unsealed post bases sitting in wet soil for half the year.
- Frost heave is not your problem; sink is. Up north, posts heave out of the ground in winter. Here, the opposite happens: saturated sandy soil compresses under the concrete mass, and the post sinks into a bowl that collects more water. You’ll see this as a low spot around the post base.

AfterReplacement Cost & What’s Included
For a full fence replacement or new installation in Orlando using Sakrete concrete for the posts, expect to pay $3,500 to $9,000. That range reflects fence length, post count, style, and whether we’re removing an old fence. A basic 100-foot privacy fence with pressure-treated 4×4 posts, three rails, and pine pickets typically lands around $4,500 to $6,000 installed. Add a gate or two, and you’re moving up in the range.
What drives the price most in Orlando is the post hole. Good contractors drill 12-inch holes, 24 to 30 inches deep, and use one 50-pound bag of fast-setting mix per hole. Some choose to hand-dig at or below spec to save time. That costs less on day one and for real money around year two or three, when the post lets go. Our price includes proper hole depth and width, two to four bags of concrete depending on post size, and plumb-and-line verification before the concrete cures.
The work is covered by our 365-Day Done Right Promise. If a post shifts or a panel comes out of level within a year of completion, we’ll come back and make it right at no charge. You’ll also get a written line-by-line price before we start, so the number you agree to is the number you pay.
Fence replacement cost in Orlando:
- Post replacement (single post): $250 – $500 depending on access and old concrete removal
- Post replacement (gate post): $400 – $800 due to wider hole and slower-setting high-strength mix
- Full fence installation, 100 linear feet, wood privacy: $3,500 – $6,000
- Full fence installation, 100 linear feet, vinyl: $5,000 – $8,000
- Full fence installation, 100 linear feet, aluminum: $5,500 – $9,000
- Full fence removal and disposal: $750 – $1,800 depending on length and post type
DIY or Call Us?
You can absolutely set a single post yourself with a bag of Sakrete and a Saturday. What you can’t do alone, easily, is set a straight fence line over 60 feet in Orlando soil conditions. If you’re doing one post, dig the hole three times the post width and at least 24 inches deep, pour the dry mix, add water, and use a level on all four sides during the set window. That’s a doable afternoon.
Where DIY goes wrong here is at scale. A fence line with 15 or 20 posts has to be straight, plumb, and aligned or every panel after the third one fights you. Our crews use string lines, batter boards, and transit checks because we’ve seen what happens when a fence wanders two inches across a backyard. And the post removal half of the job, pulling old concrete donuts cut with roots and soaked soil, is usually more physical than homeowners expect.
If you’ve got a post that’s failing or a full fence you need built right the first time, call us at (850) 920-7745. Tell me what the problem is. We’ll figure out the rest from there.
FAQs
Properly installed with a deep, wide hole and a full bag per post, Sakrete fast-setting mix will outlast the post itself, typically 15 to 25 years in Central Florida. The concrete rarely fails; the post rots at the ground line first, especially if the wood wasn’t sealed or the top of the concrete wasn’t sloped to shed water. Call (850) 920-7745 if you want us to inspect a failing post before it takes the fence down with it.
Sometimes. If the post is sound and the concrete is intact but the hole was too shallow, we can dig around the concrete mass, reset it plumb, and add new concrete with proper depth. If the post itself has rotted or the concrete has crumbled, replacement is the honest fix. Call (850) 920-7745 and we’ll give you a straight answer on which situation you have.
A single post replacement takes about two to three hours, including removing the old post and concrete, drilling the new hole, setting the post with Sakrete, and cleaning up. With fast-setting mix, the post is firm in about 40 minutes, but we recommend waiting 24 hours before reattaching rails or panels. Call (850) 920-7745 for a same-week appointment.
Yes. Our Orlando crews run Sakrete Fast-Setting Concrete Mix as standard on fence jobs, and we carry High-Strength mix for gate posts and any post holding significant weight. We also stock KraftMaid, Cambria, and Silestone materials for interior projects when you’re ready to look at the next phase of the home.
