Quikrete Home Additions & ADU: The Pasadena Owner’s Guide
If you’re planning a home addition or ADU in Pasadena and wondering about Quikrete products for the foundation, slab, or masonry work, here’s the short answer: a full home addition runs $45,000 – $130,000, while a detached ADU typically lands between $90,000 and $220,000 in this market, and Quikrete concrete mixes, anchor cement, and repair products are almost always part of the material list for these projects. Most Pasadena homeowners discover they need Quikrete-compatible work when a contractor’s estimate references “slab work,” “footings,” or “retrofit anchors” and they realize the existing concrete won’t support the new structure without repair or replacement first. We stock Quikrete products on our trucks and specify them by name, so you’ll see exactly what you’re paying for before any pour happens.
Which Quikrete Models This Applies To
For home additions and ADUs, the Quikrete products that matter most are their Concrete Mix (1101), Fast-Setting Concrete Mix (1004) for post holes and fence lines, Sand Mix (1103) for leveling and setting, and their anchoring epoxies for retrofit sill plates on older Pasadena foundations. The compatibility gotcha most owners don’t learn until too late: Quikrete Fast-Setting Concrete sets in 20 – 40 minutes, which sounds great, but in Pasadena’s summer heat (regularly 90°+ in July and August), that working window shrinks to under 15 minutes, and a rushed pour leaves cold joints that show up as cracks within the first year. We also specify Quikrete’s 5000 PSI mix for ADU footings because Pasadena’s building department requires engineered load calcs on any detached structure, and the higher PSI rating gives the engineer more room to work with. Elmstead Remodeling Pasadena is an independent contractor, not affiliated with Quikrete, but we choose their products because the specs are printed clearly on every bag and our crew can verify the mix before it goes into the wheelbarrow.

Signs Your Quikrete Home Additions & ADU Is Failing
Most of the calls we take about failing concrete work in Pasadena start the same way: a homeowner notices something odd and hopes it’s cosmetic. Here’s what we actually see on site:
- Hairline cracks running diagonally across a slab or foundation stem wall. In Pasadena’s clay-heavy soil, seasonal swelling and shrinking moves concrete more than people expect. Diagonal cracks under 1/8″ are usually cosmetic; wider cracks signal load transfer problems.
- Chalking or powdering surface on older concrete. This is spalling, and in Pasadena it’s often caused by freeze-thaw cycles in winter mornings followed by rapid warming. Quikrete’s Resurfacer can buy time, but a failing base means the patch won’t hold.
- Water pooling against the foundation after rain. Pasadena gets its rain in bursts, and if the grade slopes toward the addition instead of away, you’ll see efflorescence (white mineral deposits) or damp drywall inside within one wet season.
- Doors and windows sticking in a room that used to open fine. That’s differential settlement, and it means one corner of the slab or footing is dropping. The faster you catch it, the cheaper the fix.
- Crumbling concrete around anchor bolts or sill plates. This is the one that matters most for seismic safety. In Pasadena, retrofit anchors must bite into sound concrete. If the bolt hole is eroding, the anchor is no longer doing its job.

AfterReplacement Cost & What’s Included
For Pasadena home additions and ADUs, the concrete and masonry portion of the work typically falls between $7,000 and $18,000 for a standard slab and footing package, but the full project cost depends on what you’re building:
- Home Addition: $45,000 – $130,000
- ADU Construction (detached): $90,000 – $220,000
- Garage Conversion (ADU): $30,000 – $80,000
- Concrete Driveway (new, tied to addition): $4,500 – $12,000
Every Elmstead Remodeling Pasadena project includes a written line-item price before any work starts. You’ll see the exact Quikrete products, the bags needed, the labor, and the disposal line listed separately. No allowances, no “we’ll figure it out as we go.” The price you see on paper is the price you pay at the end – no footnotes. And because this is structural work, our 365-Day Done Right Promise applies: if something settles, cracks, or fails within a year of completion, we come back and make it right. Graham Stein signs off on every scope we write, and he’s been swinging a hammer across the San Gabriel Valley for nearly two decades.
DIY or Call Us?
Mixing a bag of Quikrete for a mailbox post is one thing. Pouring a footing for an ADU that needs to pass a Pasadena building inspection is another thing entirely. Here’s the honest split: you can safely check your existing concrete for spalling, measure cracks with a dollar bill (if the bill slides in, mark the crack and watch it monthly), and verify that your downspouts push water at least 3 feet away from the foundation. What you should not do yourself is pour structural concrete, drill and epoxy anchor bolts into a stem wall, or attempt to level a settled slab with self-leveling compound. These require a building permit in Pasadena, and the inspector will want to see bar placement, mix documentation, and clean-out details. Screw up a footing and you’re looking at jackhammering out your own work. If you’d rather skip that lesson, call us at (626) 714-2992. We’ll walk the site with you and tell you what actually needs doing.
FAQs
Properly mixed and poured Quikrete concrete in a Pasadena foundation or slab lasts 50 – 75 years before significant structural degradation, assuming the grade drains correctly and the mix was specified at the right PSI. The failure point is almost never the concrete itself; it’s water, poor compaction, or a rushed pour in summer heat.
Yes, if the crack is under 1/4″ and there’s no vertical displacement between the two sides, we can route and seal it or use Quikrete’s crack repair products with a flexible sealant. If one side of the crack sits higher than the other, the slab section has moved and Pasadena code requires a structural repair, not a patch. Call (626) 714-2992 and we’ll tell you which situation you have.
For a standard home addition foundation and flatwork package, plan on 3 to 5 working days from form-setting through final pour and finish. An ADU with deeper footings and a more involved slab runs 5 to 7 working days. Weather in Pasadena rarely delays pours, but we schedule around heat for a good finish.
Yes, we keep Quikrete Concrete Mix, Fast-Setting Mix, Sand Mix, and anchoring epoxy on our trucks, along with the rebar, wire mesh, and form materials we’d need for a standard Pasadena addition or ADU pour. Larger quantities get delivered directly from our supply yard, and you’ll see the product names on your written estimate before we order anything.
Questions about your specific project? Call (626) 714-2992 and a live person will answer. We’ll schedule a walkthrough, put the scope and price in writing, and tell you exactly which Quikrete products are going into your Pasadena project before the first bag is opened.
