PMN Pomona Masonry provides foundation repair, brick work, retaining walls, and masonry restoration to homeowners in Ontario, CA. We know the Inland Empire housing stock, from the older homes near Euclid Avenue to the stucco subdivisions on the south side, and we respond within one business day.
Ontario's clay soils expand when they absorb winter rain and then shrink back during the long dry season - a cycle that puts steady upward and downward pressure on foundations built 30 to 60 years ago. Our foundation repair service addresses cracking, settling, and structural movement before it affects the rest of the house.
Ontario's mix of older established neighborhoods and newer hillside subdivisions both see the same problem when seasonal rains hit: soil moves where there is no wall to hold it back. We build concrete block and natural stone retaining walls with proper drainage to manage that movement before it erodes landscaping or undermines structures.
The older homes near Euclid Avenue and downtown Ontario were built with brick and stone that has been exposed to decades of Inland Empire heat and the occasional freeze. Restoration work on these properties requires matching original materials carefully so the repaired sections do not look out of place against the rest of the facade.
Ontario's temperature swings from over 100 degrees in summer to near freezing on winter nights create constant expansion and contraction stress on brick walls. Spalled faces, cracked units, and loose mortar joints are the typical result on homes built before 1980, and catching them early prevents more extensive damage.
Many mid-century ranch homes in Ontario have original concrete driveways that have cracked and heaved from years of clay soil movement. Installing interlocking pavers over a properly prepared base handles soil movement better than poured concrete and adds curb appeal to homes that have had the same worn driveway for 40 years.
Brick homes near Ontario's historic downtown core often have mortar joints that have been weathering for 70 or 80 years. Tuckpointing removes the crumbling outer layer and fills each joint with fresh mortar that bonds tightly to the existing brick, sealing out moisture and strengthening the wall without changing how it looks.
Ontario is one of the Inland Empire's larger cities, and its housing stock covers a wide range of ages and construction types. The neighborhoods closest to downtown and Euclid Avenue have homes built in the 1920s through 1950s - properties with original stucco, older brick detailing, and foundations that were poured when concrete mix designs and soil testing were far less sophisticated than they are today. These homes face a specific challenge from Ontario's clay-heavy soils, which expand during winter rains and shrink back in the dry season, putting lateral pressure on walls and vertical pressure on foundations every year.
The newer parts of Ontario, particularly the subdivisions built in the 1990s and 2000s south of the 60 freeway, have different but equally real masonry needs. Stucco on tile-roofed tract homes is reaching 25 to 30 years old, which is the age range when hairline cracks become water entry points. Block walls between properties, concrete driveways, and patio slabs all see the same soil movement and thermal cycling that affects older homes. Understanding which problems are typical for which era of construction is how you give an accurate estimate and avoid unexpected surprises mid-project.
Our crew works throughout Ontario regularly, and we understand the local conditions that affect masonry work here. We pull permits through the City of Ontario Building and Safety Department and are familiar with the requirements that apply to structural masonry in this jurisdiction. The housing in Ontario's established neighborhoods near Euclid Avenue requires a different approach than the newer stucco homes near Ontario Mills, and we bring that distinction to every estimate we do.
Ontario borders Pomona to the west and Upland to the north, and we serve homeowners across the entire region. The soil conditions, climate, and housing character in this part of the Inland Empire are consistent enough that experience in one city translates directly to the next. If you are in Ontario and need an estimate, we will be straightforward about what the work involves and what it costs.
Call us or submit the contact form on this page. We respond within one business day and can schedule an on-site visit the same week in most cases.
We come to the property, assess the scope of work, and give you a written estimate at no charge. We explain exactly what the repair involves and why, so you can make an informed decision without any pressure.
For jobs requiring a permit from the City of Ontario, we file the permit application and manage that process. We then schedule the work at a time convenient for your household and keep you informed about what each day involves.
When the work is done, we clean up the job site and walk through the finished work with you before we leave. Any concerns are addressed on the spot before the job is closed out.
We serve all of Ontario and the surrounding Inland Empire cities. No pressure estimates, one-business-day response, and a crew that knows this area. Call or fill out the form to get started.
Ontario is a city of about 185,000 people in San Bernardino County, roughly 35 miles east of downtown Los Angeles. The city spans a wide range of neighborhoods, from its older historic core near Euclid Avenue - a National Register-listed boulevard lined with a double row of pepper trees and surrounded by Craftsman bungalows and Spanish Colonial homes - to the mid-century ranch neighborhoods built in the 1960s and 1970s and the larger tract subdivisions developed through the 1990s and 2000s on the city's southern and eastern edges.
Ontario is home to Ontario International Airport, one of the busiest cargo airports in the western United States, and Ontario Mills, one of California's largest outlet retail destinations. The city borders Pomona to the west and Upland to the north, and sits in the heart of the Inland Empire where the San Gabriel Valley transitions into a broader inland plateau. We serve homeowners throughout Ontario and all surrounding communities.
