RCM Rancho Cucamonga Masonry builds and repairs retaining walls, concrete block fencing, driveway pavers, and brick work for homeowners across Fontana, CA. We have served the Inland Empire since 2020 and know the hillside terrain, clay-soil movement, and aging housing stock that makes masonry work in Fontana different from a flat subdivision job anywhere else. Every inquiry gets a reply within 1 business day.

North Fontana sits on sloped terrain where grade changes and hillside lots require walls that handle real soil pressure and drainage load - not just decorative borders. Our retaining wall construction is designed for the actual load behind the wall, with proper drainage built in to prevent the pressure buildup that causes failures after winter rains.
Fontana's older neighborhoods have concrete block perimeter fencing that has been sitting on clay soil through decades of wet winters and dry summers. Walls that have started to lean or show horizontal cracking at mortar joints are under active structural stress - we repair or rebuild them before a section comes down in a Santa Ana wind event.
Fontana summers regularly push past 100 degrees, and poured concrete driveways in this climate develop cracks as they expand in the heat and shift with the clay soil below. Pavers tolerate that movement better than solid slabs and allow individual sections to be lifted and releveled if the ground settles unevenly.
Ranch homes from the 1970s and early 1980s in central Fontana often have brick mailbox posts, entry pillars, and decorative accents where original mortar has receded from the face over the years. Repointing those joints before water gets behind the brick prevents a cosmetic issue from becoming a structural one.
Fontana's clay-heavy soils shift with every wet and dry cycle, and homes built in the 1970s and 1980s sometimes show the results: interior cracks, sticking doors, or sloped floors that got worse after a particularly wet winter. A masonry evaluation early keeps a minor foundation issue from turning into a major one.
Older Fontana properties that went years without masonry attention often need more than a simple repair - efflorescence buildup, widespread mortar erosion, and surface spalling require systematic restoration rather than spot fixes. We assess the full extent before recommending a scope, so the restored section does not stand out against untouched areas nearby.
Fontana is one of the largest and fastest-growing cities in San Bernardino County, with a housing stock that covers a wide range of ages and types. The city's older neighborhoods near the city center have ranch-style homes built in the 1970s and early 1980s where original block fencing, mortar, and concrete flatwork is now 40 to 50 years old. North Fontana, developed heavily from the late 1990s through the mid-2000s, has a different problem: those homes are hitting the age where retaining walls, concrete work, and exterior masonry need their first serious attention, and many homeowners are dealing with that for the first time. The terrain in North Fontana also adds a layer of complexity - sloped lots with grade changes require walls designed for actual drainage load, not just for appearance.
Fontana summers regularly reach 105 degrees and above, accelerating the breakdown of mortar and exterior sealers more rapidly than in coastal areas. Santa Ana wind events in fall and winter can gust past 60 mph, putting real force on aging block walls and exposed masonry surfaces. Winter rains bring the additional concern of water pressure behind retaining walls that were not built with adequate drainage - a common cause of failure in residential retaining walls throughout the Inland Empire. The City of Fontana Building and Safety Division requires permits for structural masonry work, and we are familiar with the process for Fontana specifically.
Our crew works throughout Fontana regularly, and we understand the local conditions that affect masonry work here. We pull permits for structural work through the City of Fontana Building and Safety Division and know which projects require inspection sign-off and which do not. Fontana's housing stock spans multiple construction eras, and the masonry profile of a 1975 ranch home in central Fontana is very different from what we find on a 2003 two-story home in a North Fontana subdivision - we adjust our approach to what the structure actually needs rather than applying a single formula to every job.
Fontana is a large city that most residents navigate by major corridors: Sierra Avenue runs north-south through the city, and Foothill Boulevard and the I-10 freeway anchor the southern edge. The neighborhoods south of the freeway tend to have older housing, while the communities north of Arrow Boulevard and toward the foothills are newer and include many of the sloped lots where retaining walls are most commonly needed. The Auto Club Speedway sits in the southern part of the city and is the local landmark most Fontana residents know by name.
We serve Fontana and the directly adjacent Rialto, CA to the east, where similar clay-soil and aging housing stock conditions create comparable masonry needs. If your property is near the Fontana-Rialto boundary, we cover both sides of that line.
Call or submit the contact form and we get back to you within 1 business day. We confirm your Fontana address and schedule a time to visit that fits your availability.
A mason comes to your property, inspects the masonry, and provides a written estimate. We explain what needs to be done, whether a permit is required, and the full cost - no surprises after you sign.
We arrive on the agreed date with materials suited to your existing masonry type. Most Fontana residential projects finish in one to four days depending on scope and whether inspections are required.
We clean up each day and do a final walkthrough with you before leaving. We stand behind our work and are reachable if any question comes up after the project is complete.

(909) 515-5018Fontana is one of the largest cities in San Bernardino County, with a population of roughly 214,000 people as of the 2020 Census. The city sits at the western edge of the Inland Empire, where the flatlands meet the foothills of the San Gabriel Mountains. About 60 percent of housing units in Fontana are owner-occupied, and the city has a wide mix of housing ages - from ranch-style homes built in the 1970s near the city center to large two-story subdivisions in North Fontana that went up in the late 1990s and early 2000s. The city is also a major logistics hub in Southern California, with a large number of distribution centers along its freeway corridors. The Auto Club Speedway, a NASCAR-affiliated track that opened in 1997, is one of Fontana's most recognizable landmarks and sits in the southern part of the city.
Fontana borders several other Inland Empire cities that share similar housing and soil conditions. To the west lies Rancho Cucamonga, CA, where foothills terrain and clay-soil movement are familiar masonry concerns for homeowners. Sierra Avenue and Baseline Road are the major east-west and north-south arteries that most Fontana residents know well. The elevation difference between the southern and northern parts of the city means that homes in North Fontana can experience slightly cooler winters and greater grade-related drainage challenges than properties near the freeway corridors to the south.
