Premier Hesperia Concrete & Masonry is a masonry contractor serving Ontario, CA, building and repairing brick walls, concrete block walls, driveway pavers, and outdoor masonry structures for Ontario homeowners from the historic Euclid Avenue corridor to the newer subdivisions near the southern end of the city.

Ontario has one of the most varied housing stocks in the Inland Empire - from 1920s Craftsman bungalows near Euclid Avenue to 2000s-era stucco tracts near Ontario Mills - and each requires a different approach to new brick wall work. Our brick wall installation work is designed with Ontario's clay soil movement and seasonal temperature swings in mind, so footings and mortar are specified to hold up through the expand-and-contract cycle without cracking open in a few seasons.
Block walls define property lines on nearly every residential lot in Ontario, and many of the walls installed alongside the mid-century ranch home developments of the 1960s and 1970s are now showing deteriorated mortar joints, leaning sections, and crumbling caps. Santa Ana winds put real lateral pressure on aging block walls each fall, and proactive repair before a section fails is far less disruptive than post-collapse emergency work.
Ontario's clay-heavy soils are the main reason homeowners here see driveway cracking and heaving even on relatively young concrete. Clay absorbs the winter rains that Ontario receives between November and March, swells under the slab, then shrinks back in the long dry summer - and that cycle breaks up poured concrete faster than it would in sandy or stable soil conditions. Paver systems tolerate that movement better and are easier to spot-repair when individual units shift.
The older neighborhoods near downtown Ontario and the Euclid Avenue corridor contain homes built between the 1920s and 1940s, many with original brick chimneys, planters, and entry columns that have not had mortar maintenance in decades. Repointing those joints and stabilizing loose brick now costs a fraction of what full reconstruction would run if water infiltration is allowed to work into the wall cavity over another few rainy seasons.
Ontario's expansive clay soils create foundation movement issues that are common across all eras of the city's housing stock. Older homes near Euclid Avenue sometimes have original poured concrete foundations that have been settling for 70 or 80 years, while newer ranch homes from the 1960s and 1970s show footing cracks from decades of clay expansion and contraction. Catching stem wall cracks and settlement signs early avoids the larger costs that come with water intrusion into the foundation.
Ontario's brief but real frost season - overnight temperatures drop below freezing several times each December through February - accelerates mortar joint deterioration in brick and block structures that were built without frost-resistant mortar mixes. Open joints then admit moisture that Ontario's winter rains provide in volume, and that combination is what drives the spalling and joint failure that homeowners notice after a wet winter followed by a hot, dry spring.
Ontario is one of the most diverse cities in the Inland Empire in terms of housing age. The neighborhoods nearest to historic Euclid Avenue - the tree-lined boulevard listed on the National Register of Historic Places - contain homes built as early as the 1910s and 1920s. A few miles to the south, near Ontario Mills mall and the Ontario International Airport corridor, the same city has two-story stucco tracts from the 1990s and early 2000s. Those two types of homes have almost nothing in common from a masonry standpoint. Older homes have original brick, mortar that has had decades to deteriorate, and foundations that predate modern seismic codes. Newer homes have stucco-clad block walls, poured concrete driveways, and tile roofs where the underlayment - not the tile itself - is the first thing to fail. A masonry contractor who works in Ontario regularly encounters both, and treats them differently.
The climate in Ontario is hotter and drier than coastal Southern California, with summer highs regularly exceeding 100 degrees Fahrenheit and very low humidity for months at a time. That heat causes mortar joints and caulking to dry and crack faster, and the UV exposure bakes exterior finishes in ways that a contractor accustomed to coastal conditions would not anticipate. Ontario also gets Santa Ana winds every fall - hot, dry gusts that can exceed 60 mph and put real load on block walls, fencing, and attached masonry structures. The clay soils under most Ontario properties move with the wet and dry seasons, which puts pressure on slabs, footings, and paver bedding from below. Getting masonry work right here means accounting for all of these conditions at the design and material selection stage, not just matching what was there before.
Our crew works throughout Ontario regularly, and we understand the local conditions that affect masonry work here. One of the most practical things we have learned from working across the city is how much the housing character changes by neighborhood. The streets near Euclid Avenue - Ontario's landmark tree-lined boulevard - contain a high concentration of older homes that have original brick features, and those properties need mortar and repair materials matched to what was used in original construction. The neighborhoods around the Ontario International Airport and south toward Ontario Mills represent a completely different generation of housing where clay soil movement and driveway cracking are the dominant issues.
For permits and inspections in Ontario, we work with the City of Ontario Planning and Building Department. Knowing the permit process for this municipality - what inspections are required at which stages, and what documentation the city requires before final sign-off - keeps jobs on schedule and avoids the re-work that happens when a contractor submits incomplete plans. Ontario also shares borders with cities that have different building standards, so knowing which jurisdiction governs a specific parcel matters on properties near city limits.
We also serve nearby Upland and Rancho Cucamonga, where foothills properties and older housing stock present similar masonry challenges to parts of Ontario. If you are in any of these neighboring cities, give us a call - we know the area.
Contact us by phone or through the form on this page and briefly describe what you need and where in Ontario the property is. We reply to every inquiry within 1 business day - usually the same day for calls received before 3 PM.
We come to the property, assess the condition of existing masonry and the site conditions - soil type, drainage, nearby structures - and give you a written fixed-price quote before any work begins. There are no surprise charges added after the job starts, and we explain what is driving the cost so you understand what you are paying for.
Work is scheduled around Ontario's climate - we avoid pouring concrete or laying brick mortar during the hottest part of a summer day when temperatures are above 95 degrees Fahrenheit, and we plan around the Santa Ana wind season when fresh mortar can dry too fast or collect airborne debris. You do not need to be home during the work, but we keep you informed by phone if anything unexpected comes up.
When the job is done, we clean the work area completely - debris, mortar residue, and any material staged on your property is removed or disposed of. We do a final walkthrough with you so you can see the finished work and ask questions before we leave the site.
We serve all of Ontario - from the historic neighborhoods near Euclid Avenue to the newer homes on the south side of the city. Call us or fill out the form and we will get back to you within 1 business day.
Ontario is a city of roughly 185,000 people in San Bernardino County, sitting about 35 miles east of downtown Los Angeles in the heart of the Inland Empire. The city is one of the most economically active in the region, anchored by Ontario International Airport and a large concentration of warehouses and distribution centers along the I-10 and I-15 corridors. Despite its industrial base, Ontario has a strong residential character. The historic downtown centered on Euclid Avenue - a wide, pepper tree-lined boulevard that is listed on the National Register of Historic Places - remains one of the most recognizable stretches of road in the Inland Empire and is surrounded by some of the oldest homes in the city.

The housing stock in Ontario spans nearly a century of construction, from Craftsman bungalows near downtown to 1960s and 1970s ranch homes in the middle neighborhoods to newer two-story stucco tracts in the southern portions of the city near Ontario Mills mall. About half of Ontario's housing units are owner-occupied, which means a large share of residents have a direct financial stake in maintaining their properties. Ontario borders Upland to the north and Fontana to the east - two cities we also serve - and the masonry conditions and housing stock across all three cities share a lot in common.
