Diamond Bar Concrete & Masonry is a masonry contractor serving Pomona, CA with foundation block wall installation, brick repair, tuckpointing, and retaining wall construction. We have been working on the mid-century and historic homes throughout Pomona since 2019 and respond to every inquiry within one business day.

Pomona has a large share of homes built in the 1940s through 1960s, and the foundation block walls on many of these properties are showing their age with cracked mortar joints, water staining, and sections that have shifted out of alignment. Our foundation block wall installation work corrects both the visible damage and the drainage conditions at the base that cause block walls to fail on older Pomona properties.
The Lincoln Park neighborhood and other older parts of Pomona have homes with original brick chimneys, planters, and structural walls that are now 80 to 100 years old. Brick faces that have spalled, joints that have eroded, and sections displaced by ground movement all need careful matching and repointing to stay structurally sound. We work with historic brick homes regularly and understand the material differences between older fired brick and modern masonry products.
Pomona summers regularly exceed 95 degrees Fahrenheit, and that heat - combined with the wet-dry cycle of the local climate - dries out mortar joints faster than in cooler coastal areas. Tuckpointing removes deteriorated mortar and replaces it with fresh material before water gets behind the brick or block. On Pomona homes from the 1950s and 1960s, this is often the most cost-effective way to add years to an existing masonry structure.
Pomona properties with grade changes between street level and the home - particularly in older neighborhoods near downtown - often have retaining walls built in the mid-20th century that are past their useful life. We assess current soil and drainage conditions before recommending a replacement design, because a new wall built without addressing the cause of the old wall's failure will fail the same way.
Many Pomona homes from the post-war era were built with brick chimneys that are now 60 to 80 years old. Santa Ana winds that move through the Pomona area each fall can loosen mortar joints and displace chimney caps on older structures. We inspect and repair chimney crowns, flashing, and masonry joints before fire season so the structure stays safe and water-tight through the winter rainy season.
Pomona has more historic masonry structures than most cities of its size in the Inland Valley, and restoration work on these properties requires matching original materials closely. Cleaning, repointing, and sealing older masonry extends its life without the disruption of full replacement and is the right approach for properties where preserving the original character of the structure matters.
Pomona has one of the older housing stocks in the eastern San Gabriel Valley. A substantial share of the city's single-family homes were built between 1940 and 1970 - meaning the brick, block, and mortar on these properties has been exposed to 60 to 80 years of Southern California heat, UV, and the seasonal expansion and contraction of clay soils. Homes from this era were built to older seismic and material standards, and the masonry systems installed then were not designed to last indefinitely without maintenance. Tuckpointing, foundation block wall repairs, and chimney work are all more complicated on these structures because the original materials behave differently from modern alternatives.
Pomona summers regularly push past 100 degrees Fahrenheit, which accelerates mortar deterioration and dries out caulk and sealant around masonry penetrations faster than in coastal climates. The city also sits in the path of Santa Ana wind events each fall, which can dislodge chimney caps, push over older unreinforced brick walls, and loosen roof flashing that connects to masonry structures. A contractor who is not familiar with how these conditions affect aging masonry will often underestimate the scope of a repair and quote a fix that does not address the actual cause.
Our crew works throughout Pomona regularly, and we understand the local conditions that affect masonry contractor work here. Permits in Pomona go through the City of Pomona Building and Safety Division - a separate process from the LA County system that applies to unincorporated areas nearby - and we handle the application and coordination for every permitted scope of work we take on here.
The neighborhoods we work in most often include the older residential streets near downtown, the Lincoln Park area with its concentration of Victorian and Craftsman homes, and the properties east of the city closer to Cal Poly Pomona. The Fairplex area on the north side of the city and the residential streets around it include some of the more recently renovated properties, while the older neighborhoods closer to downtown Pomona are where we see the heaviest masonry repair demand. Major corridors like Holt Avenue, Garey Avenue, and Mission Boulevard run through the heart of those residential areas.
We serve communities on both sides of Pomona as well. Homeowners in Chino Hills to the south and in Diamond Bar to the east call us regularly, and the masonry conditions on residential properties in those areas overlap significantly with what we see throughout Pomona.
Call or use the contact form and we follow up within one business day - most inquiries get a response the same day. We ask a few upfront questions so we can come to your property prepared for what we are likely to find.
We walk the property, assess the masonry, and identify the root cause - whether that is aging mortar, drainage failure, or soil movement. You receive a written estimate before we schedule any work. No pressure, no obligation to proceed.
Structural masonry work in Pomona requires a permit from the city. We handle the application, documentation, and submission to the City of Pomona Building and Safety Division on your behalf and confirm approval before scheduling the job.
We complete the work to the written scope, clean up the site each day, and walk you through the results before we leave. If a city inspection is required under the permit, we coordinate that as well so the process is complete.
We serve Pomona homeowners directly - written estimates before any work starts, permits handled by our crew, and no subcontractors.
(909) 760-1426Pomona is a city of over 150,000 people at the eastern edge of Los Angeles County, where the San Gabriel Valley meets the Inland Empire. It is bordered by Diamond Bar to the east, Chino to the south, Ontario to the southeast, and Claremont to the north. The city covers approximately 23 square miles and has a mix of residential neighborhoods, industrial areas, and institutional campuses. The residential areas are concentrated primarily in the central and western parts of the city, with single-family homes and smaller multi-family buildings spread across both older and mid-20th-century streets. The 10, 60, and 71 freeways all pass through or near the city, making it a well-connected hub for the broader region.
The Lincoln Park neighborhood in central Pomona is one of the best-known historic residential districts in the Inland Valley, with Victorian and Craftsman homes from the late 1800s and early 1900s that draw preservation-minded buyers and owners. Cal Poly Pomona occupies the eastern edge of the city and is one of the largest universities in the Cal State system. Nearby Chino Hills to the south has newer residential development with its own masonry needs, and we serve homeowners in both communities.
