When your foundation sinks or shifts, everything above it follows. We lift and stabilize settled foundations in Mountain View using methods designed for Bay Area clay soils and seismic conditions - with permits pulled and a written warranty included.
Foundation raising in Mountain View lifts a home that has settled or sunk unevenly back toward its original level, using pier systems driven to stable soil or material injected beneath the slab to fill voids and push it back up - most jobs take one to three days for the lifting work itself once the City of Mountain View permit is in hand.
The reason foundations sink here is not mysterious. Mountain View sits on clay-heavy soils that swell in wet winters and shrink in dry summers, and that seasonal movement gradually pulls the ground away from foundations that were not designed to account for it. Homes built in the 1950s and 1960s - common in neighborhoods around Castro Street and Cuesta Park - often have shallower foundations that are more vulnerable to this cycle. Once the settling starts, doors stick, floors slope, and cracks appear in walls - and the longer it goes unaddressed, the more damage spreads to the rest of the house. For homeowners whose foundation needs to support a new slab or addition, our slab foundation building team can coordinate that work alongside the raising project.

If interior doors that used to swing freely now drag on the floor or won't close all the way, the frame around them has likely shifted. In Mountain View, this symptom often appears after a dry summer when the clay soil beneath the home has contracted and the foundation has dropped slightly. If it is happening to multiple doors or windows at once, the foundation is worth a closer look - it is easy to dismiss as a humidity issue, but that rarely explains the whole picture.
Diagonal cracks running from the corners of door frames or windows toward the ceiling are a classic sign of uneven foundation movement. Hairline cracks in drywall are common and often harmless, but cracks wider than a quarter-inch - or cracks that keep growing - suggest the structure underneath is still moving. In older Mountain View homes built before modern standards, these cracks can develop gradually over years before homeowners realize what is causing them.
If you place a marble on your hardwood or tile floor and it rolls consistently in one direction, your floor may have developed a slope from foundation settling. You might also feel it when walking - a subtle but persistent sense that one part of the house sits lower than another. This is especially common in Mountain View homes on clay-heavy soil, where uneven drying and swelling can cause one corner of a foundation to drop while others stay put.
When a foundation settles unevenly, the house above it shifts - and that movement often shows up as gaps where walls meet ceilings or where baseboards pull away from the floor. These gaps may appear gradually over months, so homeowners sometimes do not notice until they are doing a paint job or renovation. If you see gaps that were not there before, especially in multiple rooms, it is worth having a foundation professional take a look.
We handle foundation raising for settled homes using the method that fits the specific problem - not a one-size-fits-all approach. For homes with significant settling caused by soil movement or voids beneath the foundation, pier installation is typically the right choice. We drive steel piers or helical piers deep into stable soil below the active zone, then use them to support and lift the foundation from underneath. This approach addresses the root cause rather than just filling the gap. For homeowners who also need to address concrete in other parts of the home, our concrete cutting team can open slabs for access where the lifting work requires it.
For smaller, more localized problems - a sunken garage floor section, a settled patio slab, or a specific corner of the foundation - slab lifting is often the faster and more cost-effective solution. This involves pumping polyurethane foam or a grout mixture beneath the slab to fill voids and push it back up. We assess the extent of the settling and the soil conditions before recommending either approach, and we pull every required permit through the City of Mountain View's Building and Safety Division. The USGS earthquake hazard program publishes Bay Area soil and fault data that helps inform how foundation repairs in Mountain View need to account for both settling and seismic forces.
Best for significant settling caused by deep soil movement. Steel or helical piers are driven to stable load-bearing soil, then used to lift and hold the foundation at the corrected level.
Best for localized settling in garage floors, patio sections, or specific foundation areas. Polyurethane foam or grout is injected beneath the slab to fill voids and restore level.
We apply for and manage the building permit through the City of Mountain View on every structural raising project, including scheduling the city inspection at completion.
For Mountain View homes near active fault zones, foundation raising can be combined with a seismic retrofit evaluation - addressing both settling and earthquake vulnerability in one mobilization.
Foundation problems in Mountain View are rarely just an age issue - they are a soil issue. The Bay mud and expansive clay throughout the Santa Clara Valley shrink and swell with every season, and that movement is relentless. A contractor who does not account for local soil behavior when choosing a repair method may be setting you up for the same problem in a few years. Homeowners in Sunnyvale and Santa Clara deal with similar conditions, and the repair approach that works well for a home on clay soils in Sunnyvale is often the same approach we bring to Mountain View jobs.
There is also the seismic dimension. Mountain View sits between two active fault systems - the San Andreas to the west and the Hayward to the east - and a settled foundation is meaningfully more vulnerable when the ground shakes. California drought cycles have made this worse in recent years, with extended dry periods causing the clay soil to contract more severely than in wetter decades, creating larger voids beneath older foundations. Homeowners in Santa Clara and elsewhere in the county are seeing the same pattern. The ABAG earthquake hazard maps show the full picture of what Mountain View homeowners are working with - and why a thorough assessment before any foundation repair is not optional here.
You describe what you are seeing - sticking doors, sloped floors, cracks - and we ask a few basic questions about your home's age and history. This call usually takes 10 to 15 minutes. We respond to every inquiry within one business day.
We visit your property and walk the home inside and out - checking the foundation, measuring floor slope, and reading the soil conditions around the perimeter. You get a written estimate that explains what we found, what we recommend, and why, before you commit to anything.
We apply for the building permit through the City of Mountain View's Community Development Department on your behalf. The permit process typically takes one to two weeks. Once the permit is approved, we schedule the work.
The crew installs piers or injects lifting material - depending on the method we recommended - and you may notice doors and windows moving slightly as the house levels out. After the work is complete, the city inspector reviews it as part of the permit. We patch access holes, clean up, and walk you through everything before we leave.
We come to your Mountain View home, assess what is actually happening, and give you a written estimate you can compare. No pressure, no obligation.
(650) 582-0099The clay-heavy ground across the Santa Clara Valley behaves differently from most of the country, and we design every foundation raising project around it. A method that works on sandy or loam soil elsewhere may fail here within a few years. We factor in local soil behavior from the first assessment - not as an afterthought.
We pull the required building permit through the City of Mountain View on every structural raising project and schedule the city inspection at completion. That documentation protects you legally, keeps the work on the record, and gives future buyers proof the repair was done correctly - which matters in a market where home values are this high.
Foundation work is a significant investment, and we do not expect you to decide at the end of the site visit. You receive a written estimate that you can take time to review and compare. The number you agree to at the start is the number you pay at the end, barring something genuinely unexpected that we discuss with you before proceeding.
Mountain View sits in one of the more seismically active parts of the country, and a properly raised and stabilized foundation is more resilient when the ground shakes. We are familiar with the FEMA P-312 retrofitting guidelines and can discuss whether additional seismic strengthening makes sense alongside the raising work for your specific home.
Foundation work is one of the highest-stakes repairs a homeowner can make, and the combination of Bay Area clay soils, seismic exposure, and high home values means the margin for error is small. We bring local knowledge, proper permitting, and a no-pressure process to every job - so you end up with a stable home and the paperwork to prove it.
