Serving Rialto, CA and surrounding areas. (909) 546-5159
Rialto Concrete and Masonry is a masonry contractor serving Montclair, CA with walkway construction, foundation repair, retaining wall construction, and brick repair for homes throughout the city - from the postwar ranch homes near Central Avenue to the quieter residential streets closer to the foothills. We have worked in the Inland Empire since 2020 and we respond to new inquiries within one business day.
Most Montclair homes have concrete walkways that were poured 30 to 50 years ago over alluvial soil that has been shifting ever since. The cracking and uneven sections you see are not just cosmetic - they are a tripping hazard and a sign that the base underneath has moved. Our walkway construction work addresses the base problem first, then pours a properly sloped slab with control joints spaced for the heat cycles specific to this part of the Inland Empire.
Montclair homes are built on slab-on-grade foundations - standard practice throughout Southern California - but slabs on alluvial soil can crack or shift when the ground beneath them moves. We assess slab cracks and foundation masonry on Montclair properties before small problems become water intrusion issues, and we repair what can be fixed before recommending replacement.
Montclair sits at roughly 1,100 feet at the base of the San Gabriel Mountains, and some properties - particularly on the north side of the city closer to the foothills - have grade changes that need proper retaining structures. Heavy winter rain saturates the alluvial soil and puts sustained lateral pressure on walls, so we build with drainage integrated from the start and footings sized for this soil type.
Montclair's typical lot has a concrete driveway that was poured when the home was built and has been cracking and sinking ever since. Paver systems are a durable alternative because individual units can be lifted and re-laid if the base shifts again, rather than requiring full slab replacement. They also give homeowners more design options when refreshing a front yard as part of a water-wise landscaping update.
Older homes in Montclair often have original brick chimneys, low garden walls, and decorative brick features that have not been touched since they were built. Mortar joints that have dried out or cracked through in the Inland Empire heat let water into the brick assembly during winter storms. We repoint failing joints and repair spalled brick using mixes suited to the existing work, not generic patching compound.
CMU block walls on property lines are standard throughout Montclair, and many of them date from the same era as the homes they border - which puts them at 40 to 70 years old in parts of the city. Mortar joint failure, cracked block units, and leaning sections are all common at that age. We repair sections where damage is isolated and rebuild from the footing when the wall has moved too far to patch reliably.
Montclair's housing stock is predominantly postwar construction - single-family ranch homes built between the late 1940s and the early 1980s, mostly with stucco exteriors and slab-on-grade foundations. At 40 to 75 years old, these homes are at the age where original concrete flatwork, block walls, and foundation masonry are showing real wear rather than cosmetic aging. The alluvial soils common at the base of the San Gabriel Mountains shift with each wet and dry season, which means the ground under every Montclair slab and footing has been moving since the home was built. Masonry work that does not account for that movement will fail again, often faster than the original did.
The climate compounds the wear. Montclair summers regularly reach 95 to 100 degrees Fahrenheit, and the intense UV exposure and heat cycles dry out mortar joints and concrete surfaces faster than in coastal California. Santa Ana winds arrive every fall, and the hot, dry conditions during those events further stress exterior masonry and stucco. Winter brings occasional overnight frost that can open up cracks that formed during the dry summer months. As noted by the National Weather Service San Diego office, the Inland Empire sees temperature swings that put more thermal stress on building materials than most Southern California homeowners expect.
Our crew works throughout Montclair regularly, and we understand the local conditions that affect masonry work here. We pull permits through the City of Montclair Building and Safety Division and are familiar with the inspection process for structural masonry, retaining walls, and concrete flatwork that connects to the public sidewalk. Montclair is a compact city - most of the residential neighborhoods are within a short distance of Central Avenue and the 10 freeway corridor - so we can typically schedule site visits and project starts quickly without a long wait.
Montclair Place on Central Avenue is one of the most recognized landmarks in the city, and the residential neighborhoods that surround it represent the bulk of the city's single-family housing stock. Monte Vista Avenue runs north-south through the heart of those neighborhoods and is a useful reference point for where most of our Montclair project calls come from. The Montclair Metrolink station connects the city to the wider region, and the neighborhoods near the station have a mix of older homes and newer infill development that we see regularly.
We also serve neighboring communities along the same western Inland Empire corridor. Homeowners in Rancho Cucamonga, which sits just north and east of Montclair, can reach us for the same range of masonry services. We also cover Ontario, which borders Montclair directly to the west and has similar postwar housing stock and soil conditions.
Reach us by phone or through the online contact form - we respond to all Montclair inquiries within one business day. You do not need specs or drawings ready; we collect everything we need during the property visit.
We visit your Montclair property, assess soil conditions, slab or masonry condition, and drainage. The written estimate is all-in - materials, labor, permit fees, and any inspections. No costs get added after you sign.
For jobs that require a City of Montclair building permit - retaining walls, structural masonry, and work near the public sidewalk - we handle the permit application before any work starts. You do not need to deal with the building department; that is our job.
We complete the masonry work, schedule any required city inspections, and clean up the site before we leave. Most residential walkway and concrete jobs in Montclair take one to three days; larger structural projects run longer and we give you a schedule upfront.
We serve Montclair homeowners with free on-site estimates, permit handling, and masonry work built for the soil conditions and housing stock specific to this part of the Inland Empire. Call us or fill out the form - we respond within one business day.
(909) 546-5159Montclair is a city of about 38,000 people in San Bernardino County, sitting at the eastern edge of the Los Angeles metro area and bordered by Ontario to the west and Pomona to the east. The city sits at roughly 1,100 feet in elevation at the base of the San Gabriel Mountains, giving it a foothill setting that shapes its soil conditions and drainage patterns. Montclair Place - the regional shopping mall on Central Avenue - is the city's most recognized landmark and a reference point locals use to describe where things are. The city of Montclair was incorporated in 1956, which roughly marks the start of its primary residential building era.
The housing stock is dominated by single-family homes built between the 1950s and the 1980s, laid out on a grid of quiet residential streets with modest lot sizes and concrete driveways, front walkways, and backyard patios that are now well past their expected service life in most cases. Most of the homes are owner-occupied, and the city has a stable, neighborhood character that homeowners invest in maintaining. Neighboring Ontario and Rancho Cucamonga share similar building stock and soil conditions and are also within our regular service area.
