A sunken slab does not have to mean a full replacement. We lift settled concrete back to level the same day, at a fraction of the cost of tearing it out.
Foundation raising in Chino Hills is the process of lifting a sunken or uneven concrete slab back to its original level by pumping material into the void underneath, and most residential jobs are completed in a single day without tearing out the existing concrete. The slab itself is usually still structurally sound - it just needs support underneath it again.
If you have noticed your driveway or patio sitting lower than it used to, doors that stick for no clear reason, or gaps forming where concrete meets a wall or step, those are all signs the ground underneath has shifted. In Chino Hills, the expansive clay soils that expand in wet winters and shrink in dry summers are the most common reason foundations settle - and it is a pattern we see often, especially on the hillside graded lots throughout the city. If you are also dealing with broader structural concerns, our slab foundation building service covers full replacement and new construction when raising is not the right answer.
Call us or send a request and we will respond within one business day to talk through what you are seeing and schedule a free on-site assessment.
When the ground under your foundation shifts, the frame of your home can shift with it. A door that used to swing freely but now drags on the floor, or a window that suddenly takes effort to open, is often one of the first signs that something has moved underneath the slab - even slightly.
Walk the perimeter of your home and look where the concrete meets the house, a porch step, or a garage wall. A gap that was not there before - even a small one - means the slab has dropped away from the structure. In Chino Hills, this often appears after a dry summer when the clay soil has contracted and pulled away.
Place a marble on your floor and watch what it does. If it rolls consistently toward one side of the room, the floor and the slab beneath it may have settled unevenly. This is especially common in Chino Hills homes built on graded lots where one side of the foundation sits on more compacted fill than the other.
After a winter rain, walk your property and notice where water collects. If it consistently pools against the side of your house or near the base of a concrete slab, that water is soaking into the soil underneath and eroding the support over time - a pattern that is especially common on the hillside lots throughout Chino Hills.
We offer two main approaches for foundation raising in Chino Hills: polyurethane foam injection and traditional cement-based slurry (sometimes called mudjacking). Foam injection uses smaller holes, cures in about 15 minutes, and is lighter on already-stressed soil - which makes it the preferred choice when speed and minimal disruption matter most. The slurry method uses larger holes and takes longer to cure but can be the right fit for certain soil conditions and project sizes. We assess each situation and recommend the method that suits your specific slab, soil, and budget rather than defaulting to one approach for every job. Every estimate includes a review of drainage and soil conditions, because a lift that does not address what caused the settling in the first place is only a temporary fix.
For slabs that are too damaged to raise - broken into multiple pieces or severely cracked through - we handle full concrete cutting and removal as part of preparing for a proper replacement. We will tell you honestly which option makes more sense for your home so you are not spending money on a fix that will not hold.
Fast-curing polyurethane foam lifts the slab through small drilled holes and is ready to walk on in minutes - best for jobs where speed and minimal hole size matter.
A cement-based mix pumped under the slab to fill voids and raise it back to level - a cost-effective option for larger areas where foam cost becomes prohibitive.
We evaluate how water moves across your property during the site visit - because drainage problems that caused the settling need to be identified before the lift begins.
We handle permit requirements through the City of Chino Hills and guide you through HOA approval processes common in many Chino Hills communities.
Chino Hills is built across rolling hills, and much of the residential housing stock was constructed during the suburban expansion of the 1980s and 1990s. Those homes are now 30 to 40 years old - and the clay-heavy soils they sit on have been expanding and contracting through wet winters and dry summers for decades. That constant movement is the single biggest driver of foundation settling in this area. On sloped and graded lots, which are common throughout the city, water naturally wants to run toward the foundation, quietly eroding soil support year after year before any visible sinking appears. If your home is in a hillside neighborhood and you have not had a foundation assessment in years, it is worth a look before a small drop becomes a larger problem.
Many of the calls we get for foundation raising come from neighborhoods in Chino Hills where hillside grading and clay soils combine to accelerate settling. We also serve homeowners in nearby Chino where similar soil conditions and housing age create the same patterns. In both areas, timing your repair after the wet season - when soil has stabilized - tends to produce better long-term results.
Tell us where the settling is and what you have noticed - sticking doors, visible gaps, sloping floors. We respond within one business day and schedule a free on-site visit at a time that works for you.
We walk the affected area with you, measure how much the slab has dropped, and assess drainage across your property. You get a written estimate that covers the method, scope, and total cost - no surprises once work begins.
Depending on scope, we coordinate with the City of Chino Hills Building and Safety Division and help you navigate HOA approval requirements common in many local communities. This step protects your home value and keeps the process clean.
The crew drills small holes, pumps material underneath until the slab returns to level, patches the holes, and cleans up. Most jobs are done in a few hours. With foam injection, you can walk on the surface the same day.
No obligation. Written scope and price before any work begins. We respond within one business day.
(909) 729-4539We have worked on foundations across Chino Hills since 2023 and understand how the area's expansive clay soils behave through wet winters and dry summers. That local knowledge shapes how we assess drainage, recommend lifting methods, and set realistic expectations for how long a repair will hold.
Unpermitted foundation work is one of the most common problems that surfaces during a home sale in California. When the scope requires a permit, we pull it through the City of Chino Hills so the work is officially documented. For more information on local permit requirements, see chinohillsca.gov.
Not every sunken slab is a good candidate for raising. If your concrete is crumbling or broken into multiple pieces, we will tell you that replacement is the better long-term answer rather than lifting it and sending you a bill for a fix that will not hold. You get our honest read on the situation, not just the option that costs more.
Your written estimate specifies the method, the number of injection points, what is included, and the total price. The American Society of Concrete Contractors recommends written estimates for all foundation work - so you can compare contractors fairly and walk into the job without anxiety about the final bill.
Foundation raising is a job where the details matter more than the speed. We monitor the lift throughout the process, check level as we go, and stop when the slab is back in the right position - not when we think it looks close enough.
When a slab is too damaged to raise, precise cutting removes the affected section cleanly so replacement concrete bonds and cures correctly.
