OT Ontario Masonry is a licensed masonry contractor serving Upland, CA, with experience in retaining wall construction, brick repair, and block wall replacement for homeowners across the city. We have been serving the Inland Empire since 2020, and every structural masonry job we take on in Upland is permitted through the city and inspected before we close out the project.
Upland sits at the base of the San Gabriel Mountains, and many properties - particularly on the north side of the city near the foothills - sit on terrain with meaningful grade changes. When those slopes are not properly retained, winter rain concentrates drainage pressure against the foundation and gradually erodes the yard. Our retaining wall construction service covers new wall installation and aging wall replacement, with permits and city inspections included on every structural job.
Block wall fencing is common on Upland properties built in the 1960s and 1970s, and many of those walls are now well past 40 years old. The expansive clay soil under these properties has been cycling through wet and dry seasons for decades, and the cumulative movement shows up as horizontal cracking and outward bowing - both signals that a rebuild is overdue rather than optional.
The older homes near Euclid Avenue and Upland's historic downtown often have original brick that has been repaired piecemeal over the years, leaving mismatched mortar and open joints. We source brick that matches the existing color and texture so the repaired section blends into the rest of the wall rather than standing out as a patch.
The clay soils throughout Upland expand and contract with each wet and dry season, putting repetitive vertical and lateral stress on concrete slabs and foundation walls. Mid-century ranch homes from the 1950s to 1970s are particularly susceptible - if you are seeing new cracks in your interior floors or door frames that have started sticking, the soil beneath the slab is worth an inspection.
Upland has a large stock of mid-century homes where original brick veneers, chimneys, and exterior block structures have never been fully restored. Decades of UV exposure, seasonal temperature swings, and deferred maintenance leave joints failing and surfaces stained. A full restoration addresses the entire surface systematically rather than patching individual spots that keep reappearing.
Upland's older neighborhoods have mature trees and dense landscaping that hold moisture near masonry surfaces longer than bare ground would. That sustained moisture, combined with the brief winter rainy season, accelerates mortar joint deterioration on chimneys, planters, and garden walls. Tuckpointing removes failing mortar and replaces it with fresh material before water finds a path behind the surface.
Upland has a housing stock that skews older than many nearby Inland Empire cities. A large share of homes were built between the 1950s and 1980s, which puts them at 40 to 70 years old today. Mid-century ranch homes with original stucco, block fencing, and concrete flatwork are common throughout the city, and all of those materials have been under stress since they were first poured or laid. The mature trees that lineUpland's older neighborhoods near Euclid Avenue add another complication - roots from trees planted decades ago have had time to work under driveways, lift walkways, and crack older concrete flatwork in ways that no surface patch can permanently fix.
The local climate compounds the wear on masonry. Upland summers regularly push past 95 to 105 degrees, and the high UV exposure at the base of the San Gabriel Mountains accelerates the breakdown of mortar and sealants faster than in coastal areas. The expansive clay soils common throughout San Bernardino County swell with each winter rain and shrink back in the summer heat, and that annual cycle cracks concrete slabs, driveways, and retaining walls with the kind of consistency that makes the damage feel routine - but routine does not mean it should be ignored. Masonry under clay soil pressure that goes unaddressed typically gets more expensive to fix with each passing year.
Our crew works throughout Upland regularly, and we understand the local conditions that affect masonry work here. We pull permits through the City of Upland Building and Safety Division for retaining walls and structural block wall jobs, and we coordinate inspection scheduling with the city so you do not have to manage that process on your own. Every permitted job gets the required city sign-off before we consider the project closed.
Upland stretches from the flatter sections near Foothill Boulevard in the south up to the hillier terrain at the base of the San Gabriel Mountains to the north, where properties near Mount Baldy face real drainage and slope challenges. The older neighborhoods near the historic Upland Train Depot and Euclid Avenue have some of the city's densest tree canopies and oldest concrete flatwork - both of which affect the scope of any masonry job in those areas. Newer subdivisions in north Upland, closer to Rancho Cucamonga, have tile roofs and two-story homes that are hitting the 25-to-40-year mark where exterior systems need their first serious attention.
We also serve adjacent communities on a regular basis. If you are in Rancho Cucamonga to the north or in Claremont to the west, we cover those areas with the same crew and standards.
Call us at the number above or fill out the contact form and we will follow up within one business day to schedule a visit. You do not need a full scope ready - describing what you are seeing on the property is enough to get things moving.
We come to the property, assess what we are looking at, and give you a written estimate before work begins. If the job requires a city permit, we tell you upfront and include the permit cost in the estimate - no surprise fees added after you sign.
Once you approve the estimate, we provide a start date and schedule. For permitted retaining wall and block wall jobs, we coordinate the city inspection at the footing stage and give you advance notice so you know when inspectors are coming to the property.
When the job is complete, we walk the finished work with you before calling it done. Permitted projects receive a final city inspection sign-off document, which you keep for your records - useful if you sell the home or need to make an insurance claim in the future.

(909) 738-1803Upland is a city of roughly 80,000 people in San Bernardino County, sitting at the base of the San Gabriel Mountains with the distinctive silhouette of Mount Baldy on the northern horizon. The city has used the nickname "City of Gracious Living" for decades, and it shows in the tree-lined streets, well-kept residential neighborhoods, and a housing stock that skews older and more established than many surrounding Inland Empire cities. The most recognizable corridor in town is Euclid Avenue, a wide, tree-lined boulevard that runs north to south through the heart of the city and is lined with some of Upland's oldest homes and most mature landscaping. The historic Upland Train Depot near downtown dates to 1906 and anchors an older residential core where mid-century and pre-war homes are common.
Upland's homeownership rate runs above the California state average, which reflects a community where people invest in their properties for the long term. The northern part of the city, toward Rancho Cucamonga, has newer subdivisions built from the 1980s through the 2000s, while the southern and central neighborhoods closer to Foothill Boulevard blend 1950s ranch homes with small commercial corridors. To the west, Claremont borders Upland and shares a similar foothill character - both cities are part of the same service area for our crew.
