Cracked bricks, failing mortar, and earthquake damage let water into your walls and get worse every season. We repair and replace with matched materials so the finished work looks like it was always there.
Brick repair in Ontario, CA addresses cracked or damaged bricks, failed mortar joints, and structural movement in walls and chimneys, and most residential jobs are completed in one to three days. The real concern with any brick damage is water - once a crack or gap opens, moisture moves in, and in Ontario's climate it can go unnoticed for months before showing up as staining, spalling, or interior damage.
Homeowners in Ontario often reach out after noticing stair-step cracks following a wet winter, loose chimney bricks after a wind event, or white mineral staining on exterior walls. If you also have crumbling or sandy mortar between otherwise sound bricks, that is a separate job - tuckpointing handles mortar replacement without replacing the bricks themselves, and it may be all you need if the bricks are still intact.
The longer damaged brick sits, the more the underlying structure absorbs. A repair that costs a few hundred dollars now can become a multi-thousand dollar structural project if seasonal heat cycles, Santa Ana winds, and seismic movement keep working on it.
A crack pattern that follows the mortar joints diagonally - like steps on a staircase - often means the ground beneath has shifted. The Inland Empire's soil expands and contracts with seasonal moisture changes, and that movement shows up in brick walls over time. This type of crack should be looked at by a mason sooner rather than later.
Chalky white marks are mineral salts pushed out by water moving through the wall. They signal that moisture is getting in somewhere - often through failed mortar or cracked brick. In Ontario, this commonly appears after a rainy winter or when irrigation systems spray directly onto exterior brick.
Chimneys take more weather exposure than any other brick structure on a home. After a season of Santa Ana winds or a minor earthquake, it is common to find loose bricks or open gaps near the chimney cap. This is a safety issue - loose bricks at height can fall. Do not wait on a chimney inspection if you see this.
A damp patch, musty smell, or water stain on an interior wall that backs up to exterior brick is a strong sign the brick or mortar outside has failed somewhere. In Ontario, this kind of moisture intrusion tends to show up after the winter rainy season and can go unnoticed until interior finishes start to show damage.
We repair brick walls, chimneys, garden structures, and retaining walls across Ontario and the surrounding Inland Empire. Every job starts with an honest assessment of what is actually damaged - bricks, mortar, or both - so you are not paying to replace material that is still sound. For cracked or failing bricks, we source replacement material that matches the original in color, texture, and size as closely as possible. For older Ontario homes where the original brick is no longer manufactured, we source salvaged material or blend carefully.
If the bricks themselves are intact but the mortar has deteriorated, we will point you toward tuckpointing as the more targeted solution. If you are dealing with broader masonry wear - faded, stained, or weathered surfaces beyond just cracks - our driveway pavers and masonry restoration services may also be worth discussing at the same visit.
For walls with individual or grouped cracked bricks where matching the original material closely is the priority.
Suited for walls where the bricks are sound but mortar joints have deteriorated and are letting water in.
For chimneys with loose bricks, open gaps at the cap, or seismic or wind damage that makes continued fireplace use unsafe.
Addresses cracked, shifted, or failing sections of decorative or functional brick walls before they worsen or collapse.
Ontario's climate is unusually hard on masonry. Summer temperatures regularly top 100 degrees in the Inland Empire, causing mortar to expand and contract repeatedly across the years until it breaks down. The Santa Ana winds that push through every fall pull moisture out of mortar quickly, widening cracks that were already forming. Many homes in Ontario's established neighborhoods were built in the 1950s through 1980s with brick accents and chimneys that have been through decades of these cycles - and that brick is now in the repair range even if it still looks mostly solid from the street.
Seismic activity is also a factor in this part of Southern California. Even minor ground movement can open cracks in brick walls and chimneys that were already weakened by heat and wind stress. We serve homeowners across the area, including in Pomona and Montclair, where similar older housing stock and the same seasonal conditions make brick repair one of the most consistent masonry needs we address. The Brick Industry Association offers homeowner guidance on identifying brick damage and understanding repair options.
We respond within one business day. Describe what you are seeing - cracks, loose bricks, chimney damage - and we schedule a free on-site assessment. If it involves a chimney, let us know whether you have used the fireplace recently.
We walk the area, look at the damage up close, and check for anything you might not have spotted - cracks around a corner or mortar that looks fine but is already soft. You leave with a clear picture of the work and a written quote before we start anything.
We remove damaged mortar or bricks carefully, clean out the joints, and fill with material matched to the original. Most of the work is done by hand with small tools - it is not a loud or disruptive job, and the surrounding area is protected before we start.
We clean up and walk the repaired area with you before leaving. Fresh mortar needs a few days before getting wet, and full strength comes over the following month. We will tell you exactly what to avoid and for how long.
We come out, assess the full damage, and give you a written quote - no obligation and no surprises after the job starts.
(909) 738-1803Every job starts with a written estimate that spells out what will be removed, what will be replaced, and what materials will be used. You know what you are agreeing to before a single brick is touched. There are no surprises mid-job.
Ontario's older homes were often built with brick that is no longer manufactured. We source salvaged bricks and blend materials carefully to match your original wall as closely as possible - because a patch that stands out can look worse than the original damage.
Some brick repairs - particularly structural walls, retaining walls, and chimneys - require a permit in Ontario. We know the current rules and flag permit requirements before work starts, so there are no delays or fines after the job is done.
We know the conditions that drive brick damage in this part of Southern California - seismic movement, Santa Ana wind cycles, and clay soil expansion. That local knowledge shapes how we assess damage and what we recommend. The International Masonry Institute provides resources on masonry repair best practices that we refer to in our work.
Taken together, these points reflect a straightforward commitment: you get a contractor who assesses honestly, sources materials carefully, and handles the permit and HOA questions before they become your problem.
