Sakrete Home Additions & ADU: The Orlando Owner’s Guide
We install and finish Sakrete-based home additions and ADUs across Orlando, with most projects landing between $45,000 and $130,000 depending on scope, foundation work, and finish level. If your Sakrete product is failing, spalling, or cracking at the slab or stem wall, we can assess it quickly and give you a written price before any work starts. Most Orlando homeowners discover the problem the same way: a hairline crack in the slab that widens after a heavy rain, or a corner of the addition that settles and pulls away from the main house. You call because the floor is no longer level and the door frames have started to bind.
We are an independent Orlando contractor, not affiliated with Sakrete, but we work with their bag mixes and specification guides every week. When a Sakrete-based addition shows signs of failure, the fix is rarely just patching the crack. It is figuring out why the concrete moved in the first place, and that is where we start.
Key Takeaways
- Orlando home addition and ADU work on Sakrete foundations typically runs $45,000 to $130,000 installed.
- We match the right Sakrete mix to the pour, the weather, and the load.
- Written price before work starts, every time, no exceptions.
- Our 365-Day Done Right Promise covers the work for a full year from completion.
Which Sakrete Models This Applies To
Sakrete does not make a single “home addition” product. What you likely have is one of their bagged concrete or mortar lines: High-Strength Concrete Mix, Crack-Resistant Concrete Mix, Fast-Setting Concrete Mix, or Sand Mix Topping & Bedding. The right one depends on what failed and where. Fast-Setting Mix is often what Orlando handymen grab for a small ADU slab, but it is not the right call for a load-bearing stem wall in our humidity. Crack-Resistant Mix has reinforcing fibers and holds up better on flatwork that sees wet-dry cycles, but it costs about 20-30% more per bag and needs a full-depth pour, not a thin cap.
Here is the compatibility gotcha we see weekly in Orlando: if your original slab was poured with High-Strength Mix and you patch with Fast-Setting Mix, the two cure at different rates and the patch will shear at the bond line within a season or two. You need to match the patch to the parent concrete. The bag label will list the compressive strength in PSI, and the date code on the bag tells you how fresh the material is. Sakrete bags older than one year lose workability and should not be used for structural repair, period.
We also stock and work with KraftMaid cabinetry for ADU interiors and Cambria or Silestone surfaces when the project includes countertops, so you are not running between three different suppliers.
Styles & brands we work with
Signs Your Sakrete Home Additions & ADU Is Failing
- Cracks wider than a quarter inch, or cracks that grow after rain. In Orlando’s sandy, wet soil, concrete slabs move seasonally. A crack that opens and closes is usually thermal. A crack that keeps widening means soil washout or poor compaction under the pour.
- Door frames or windows in the addition that stick or refuse to latch. This is settlement, and it is rarely even across the slab. One corner is sinking faster than the rest, usually because the footer was not dug below Orlando’s shifting topsoil layer.
- Efflorescence, the white chalky buildup on the slab edge. Water is moving through the concrete and carrying minerals to the surface. It is not cosmetic. It means moisture is wicking up through the slab, and in an Orlando ADU that means flooring will cup and baseboards will rot.
- Spalling or flaking at the slab corners near downspouts. Water draining against the slab edge breaks down the surface over time. This is one of the most common Sakrete failures we see in Orlando, and it is preventable with correct grading.
- A hollow sound when you tap the slab with a hammer or screwdriver handle. Delamination, meaning the top layer has separated from the body of the concrete. It was likely over-troweled during the pour or the mix was too wet. A hollow slab is not carrying load the way it was designed to.

AfterReplacement Cost & What’s Included
In Orlando, a full Sakrete-based home addition or ADU build runs $45,000 to $130,000. At the lower end you are looking at a simple bump-out or attached studio with basic finishes. At the upper end you are talking a full ADU with kitchen, bath, separate electrical panel, and poured stem walls. A standalone ADU construction job with foundation, framing, mechanicals, and finishes typically lands between $90,000 and $220,000 depending on square footage and whether the existing pad can be reused.
| Project | Orlando Installed Range |
|---|---|
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Garage Conversion | $30,000 – $80,000 |
Every price we give is written down before work starts. That includes the concrete, the reinforcement, the forming labor, the finish work, and the cleanup. What it does not include is change orders invented mid-project. We do not do that. If structural issues surface during demo, we stop, put the new scope in writing, and get your signature before we spend another dollar.
The work is covered by our 365-Day Done Right Promise. If something is not right within one year of completion, we make it right at no cost to you. That is the warranty, stated plainly, with no fine print surprises.
DIY or Call Us?
You can check a few things yourself without touching the concrete. Look at downspout placement and whether water pools at the slab edge. Check the width of the crack with a coin. A dime is about 1.35 millimeters, a nickel about 1.95. If the crack is wider than a nickel at any point, you have real movement, not a surface blemish. What you cannot safely do yourself is determine whether the slab is still load-bearing or whether the stem wall is compromised. Cutting into a failed foundation without understanding the load path can cause a partial collapse, and no homeowner should be standing near that.

FAQs
A properly poured and cured Sakrete slab in Orlando should last 50 years or more, but our humidity and seasonal rain shorten that lifespan considerably when the slab was poured on poorly compacted soil or without a vapor barrier. If your slab is failing at year five or ten, the problem is almost never the concrete itself.
It depends entirely on the cause. Surface cracks can be routed and sealed. Structural cracks caused by soil washout or poor compaction usually require underpinning, mudjacking, or a partial re-pour. We will tell you which one you need and why. Call (850) 920-7745 for an honest assessment.
A straightforward garage conversion runs 6 to 10 weeks. A full ADU with new foundation, framing, plumbing, and electrical takes 18 to 30 weeks in Orlando, with city permitting and inspections built into that timeline. We pull the permits and pass the inspections.
Yes. Our Orlando crews carry High-Strength, Crack-Resistant, and Fast-Setting Sakrete mixes, plus bonding agents and repair mortars, so most repair assessments can be quoted and started without a supply-house delay. For full addition and ADU pours we order fresh by the pallet from our local supplier so you are not getting bags that sat in a warehouse through an Orlando summer.
