Quikrete Home Additions & ADU: The West Palm Beach Owner’s Guide
Quikrete-based home additions and ADU construction in West Palm Beach typically runs $45,000 – $130,000 for the full project, with ADUs specifically landing between $90,000 and $220,000 depending on square footage and finishes. We stock and work with Quikrete products on our trucks for foundation, slab, and masonry phases, and we can usually be on site within a few days of your call. Most West Palm Beach homeowners discover they have a foundation or slab issue the same way: a hairline crack in the driveway apron that widens after a heavy rain, or a door that starts sticking in July when the humidity sits at ninety percent for a week straight.
We’re not affiliated with Quikrete corporate. We’re a West Palm Beach general contractor that buys their materials by the pallet because we’ve seen what holds up in this soil and what doesn’t. Graham Stein, who runs Elmstead Remodeling West Palm Beach, learned slab work years ago and has watched how Florida’s sandy, shifting ground treats concrete differently than the clay he saw out West. That’s why we don’t guess at mix ratios or cure times here.
Which Quikrete Models This Applies To
If you’re matching a failed concrete section or planning a new addition, the Quikrete lineup matters more than most people expect. Their standard 5000 PSI mix is what we use for load-bearing footings and stem walls in West Palm Beach. The 3500 PSI mix works fine for sidewalks and non-structural pads. But here’s the compatibility gotcha: Quikrete’s fast-setting products, like FastSet and RapidSet, are not interchangeable for structural slabs. They’re designed for fence posts and small repairs, not for supporting a 400-square-foot addition.
You can identify the right product by the bag markings and the cured color and texture. Quikrete stamps the PSI rating and the product number near the bottom of each bag. If you’re patching an existing slab, match the aggregate size, not just the strength rating. We also stock Quikrete crack-resistant mix for West Palm Beach driveways and walkways because regular mix without fiber reinforcement tends to telegraph cracks within two seasons. For the OEM-versus-aftermarket question with Quikrete: there isn’t much of an aftermarket in bagged concrete. The brand owns the category. What we do see is people substituting cheaper bulk concrete from a local plant and wondering why the finish looks different. Quikrete’s bagged consistency is why we use it for residential work where appearance matters.

Signs Your Quikrete Home Additions & ADU Is Failing
- Stair-step cracks running through the slab edge. This usually means differential settlement. In West Palm Beach, the sandy soil shifts after heavy rains, and one corner of the slab sinks before the rest catches up.
- Doors and windows that stick only during summer months. Humidity swells framing, but if doors bind at the top corner and not the latch side, the slab underneath has moved. That’s a foundation sign, not a weather sign.
- Efflorescence, that white chalky dust on the concrete surface. Water is moving through the slab and carrying minerals up. In coastal West Palm Beach air, the salt content makes this worse than inland Florida.
- Hollow sounds when you tap the slab with a hammer. That means the slab has delaminated from the subbase. Water got underneath and broke the bond. You’ll hear a distinctive thud instead of a sharp ring.
- Cracks that widen after every hurricane season. If the crack was the width of a credit card in March and a finger-width in November, the base material under the concrete is eroding. Patching the surface won’t stop it.
Replacement Cost & What’s Included
A full home addition in West Palm Beach runs $45,000 – $130,000. An ADU runs $90,000 – $220,000. Concrete work, which includes footings, slab, and the Quikrete materials, typically makes up 8 – 15% of the total project cost. A standalone slab repair, if the foundation is otherwise sound, lands between $800 and $3,500 depending on square footage and whether we need to saw-cut and dowel into the existing concrete.
What drives the range: access to the pour site, whether we’re pumping or wheeling the concrete, how much demolition and haul-away is involved, and whether your West Palm Beach property sits in a flood zone that requires a higher elevation and more fill. Every quote includes the written material list by brand and quantity, the labor line items, and a firm start and end window. We don’t hand you an estimate and then discover problems once the crew shows up. The price for the Quikrete materials, the rebar, the vapor barrier, and the finish work is on the page before you sign anything. Our 365-Day Done Right Promise covers every completed project, including the concrete work.

You can check a few things yourself: whether cracks are growing week to week, whether water pools against the slab after rain, whether the concrete sounds hollow when tapped. Mark the ends of a crack with a pencil and date it. If it grows past the mark in a month, you have active movement. That’s worth a phone call to (728) 203-3270.
What you shouldn’t do is mix and pour structural concrete yourself. A bad batch on a non-structural pad means a cosmetic redo. A bad batch on a load-bearing footing means the framing above it is compromised, and that’s a five-figure mistake. Quikrete bags look simple, but the water ratio, the cure time, the rebar schedule, and the subgrade compaction are all specific. Get any one of them wrong in West Palm Beach’s sandy soil and the slab cracks before the paint dries. And concrete work is heavy. A single 80-pound bag is manageable. A few hundred of them is how people hurt their backs. Let us handle the pour, and you can watch from the kitchen window with a cup of coffee.
FAQs
A properly poured and cured Quikrete slab in West Palm Beach should last 30 – 50 years, though coastal salt air and seasonal flooding can shorten the surface life of exposed concrete. We’ve seen properly done residential slabs from the early 1990s still holding level, while poorly prepped ones failed in under a decade. The difference is almost always the base prep and the water ratio, not the Quikrete mix itself. Call (728) 203-3270 if you want us to look at what you have before you commit to a repair.
Yes, if the crack is stable and not widening, we can repair it with Quikrete crack sealant or epoxy injection, which costs far less than a full replacement. If the crack is active, meaning it grows or shifts, repair is temporary and you’ll be back in the same spot next year. The fix for active movement is addressing the soil underneath, not just the concrete on top. Call (728) 203-3270 and we’ll tell you honestly which situation you have after one site visit.
Most residential slab pours in West Palm Beach are done in one day of pouring, with several days of curing before framing starts. The full addition, from demolition to final walkthrough, usually runs 10 – 16 weeks in this market. Weather matters here, and afternoon thunderstorms in summer can delay a pour by hours. Call (728) 203-3270 and we’ll walk you through the timeline for your specific project.
Yes, our West Palm Beach crews carry Quikrete 5000 PSI mix, crack-resistant mix, and the standard 3500 PSI mix on the trucks for most concrete phases. For larger pours, we order pallets ahead and stage them on site under tarps. We also work with KraftMaid, Cambria, and Silestone for the finish phases of home additions and ADUs. Call (728) 203-3270 to schedule a free estimate, and we’ll walk the site with you before anything gets ordered.
