Crumbling mortar, spalling brick, and white mineral stains signal that your masonry needs attention before the next rainy season does more damage. We restore brick, stone, and block to sound condition with matched materials and proper technique.
Masonry restoration in Pomona covers repairing, cleaning, and stabilizing brick, stone, or block surfaces that have started to deteriorate, without tearing them down and starting over. Most residential jobs - a chimney repoint, a garden wall repair, or efflorescence removal on a block fence - take one to three days from start to finish.
Pomona has a large share of homes built between the 1920s and 1960s, and the original mortar on many of those structures has reached or passed the end of its useful life. The process involves removing deteriorated material, packing in fresh mortar matched to the original color and hardness, and sealing the surface so water cannot find its way back in. When bricks are also damaged from years of moisture cycling, we handle spall repair alongside the mortar work. Homeowners who have noticed crumbling joints often benefit from fireplace restoration or installation at the same time, since chimneys and firebox surrounds develop the same mortar failures as exterior walls.
White or grayish powder forming on the surface of your brick or block after a rainy winter is called efflorescence. It is very common in Pomona due to the area's mineral-rich water supply and its wet-dry seasonal pattern. It signals that moisture is getting into the masonry somewhere it should not be, and that pathway needs to be sealed before it causes deeper damage.
Press on the mortar lines between your bricks or stones. If the material feels soft, sandy, or crumbles away with gentle pressure, it has lost its binding strength. Mortar in this condition no longer keeps water out or holds the masonry units firmly in place. It needs to be replaced before the next rainy season arrives in the Pomona Valley.
Small hairline cracks in mortar joints are normal and manageable. Cracks wider than a credit card, cracks that run diagonally across multiple bricks, or cracks that appear to have grown since you last noticed them are signs of movement or structural stress. In Pomona, where seismic activity and expansive soils both shift ground over time, diagonal cracks that appear after a dry summer or a heavy rain deserve prompt attention.
When the outer face of a brick starts to peel or pop off in layers, that is called spalling. It happens when water gets inside the brick, heats up in Pomona's intense summer sun, and forces the surface apart. Once spalling starts, it tends to accelerate - each damaged brick face lets in more water, causing more damage. Catching it early means restoring the area rather than replacing entire sections of wall.
Our restoration work covers the full range of what Pomona homes typically need. For structures where the mortar has simply aged out, we remove the deteriorated material, pack in a fresh mix matched to the existing profile and color, and tool the joints to a smooth, consistent finish. This process - tuckpointing - is the most common masonry restoration task and handles the majority of what homeowners in the city are dealing with on their brick walls, chimneys, and block fences. When bricks have also been damaged by years of water intrusion, we carry out spall repair alongside the mortar work, filling or replacing affected faces so the wall looks and holds together as a unit.
We also address efflorescence - cleaning the mineral deposits from brick and stone surfaces and sealing the moisture pathway so they do not return quickly after the next rain. For homeowners whose walls have developed visible movement cracks, we assess whether the damage is cosmetic or structural before recommending a scope. Work that touches the structural integrity of a wall or foundation may require a City of Pomona permit. If your property includes natural stone surfaces in need of repair, our team also handles stone masonry restoration work, matching the original stone character as closely as possible.
Best for walls, chimneys, and fences where the mortar has failed but the masonry units themselves are still in good shape.
Suited to brick or stone surfaces where moisture damage has started to break apart the outer face of individual units.
For homeowners dealing with white mineral staining and the underlying moisture intrusion that causes it to keep returning.
Pomona sits in the Pomona Valley, where summer temperatures regularly push past 95 degrees and winter rainfall can arrive suddenly after months of dry heat. That cycle - extreme heat, slow drying, then concentrated rain - is one of the most stressful patterns masonry can face. Cracks that look minor in September can open up significantly after the first heavy December storm. The city also sits within reach of active fault systems, and masonry with failing mortar is more vulnerable to earthquake shaking than solid, well-maintained walls. A proper restoration addresses both concerns at once: sealing the wall against water while reinforcing the mortar that keeps everything structurally tied together.
Much of Pomona's older housing stock - particularly around the Lincoln Park neighborhood and the Garey Avenue corridor - features original brick and block construction that has never been professionally restored. We work on homes throughout the area, including Ontario and Upland, where the same climate conditions and older housing ages create the same restoration needs. The Metropolitan Water District of Southern California notes that this region carries relatively high mineral content in its water supply, which contributes directly to the efflorescence that appears on so many Pomona brick surfaces after the rainy season.
We respond within 1 business day. Describe what you are seeing - cracks, chalky staining, crumbling mortar - and we schedule a free on-site assessment. No commitment required to get eyes on the problem.
A mason walks the affected area with you, points out what they are seeing, and gives you a written estimate before any work is agreed to. If the project requires a City of Pomona permit, we tell you at this stage and include permit fees in the estimate.
The crew removes deteriorated mortar using grinders or chisels - this is the noisiest part of the job. Fresh mortar is then mixed, packed in, and tooled to match the original profile. Most small-to-mid jobs run one to three days of active work.
We clean the site, remove debris, and walk the finished work with you before leaving. Fresh mortar needs 24 to 48 hours before it gets wet and up to 28 days to reach full strength. We tell you exactly what to avoid during that window.

We take the time to match new mortar to the color, texture, and hardness of the original material. Using a mortar that is harder than the surrounding brick - a common shortcut - can crack older masonry rather than protect it. Proper matching is especially important on Pomona's mid-century homes, where the brick is softer than modern equivalents.
Every project begins with a written estimate that breaks out what is being done and why. You know the exact scope and price before a single tool comes out. No verbal ballparks, no surprises on the invoice - a common frustration homeowners in Pomona describe when hiring contractors.
Structural masonry repairs in Pomona require a city permit and a final inspection by a licensed city inspector. We handle the permit application and make sure the work meets the standard that triggers sign-off. That inspection is not just red tape - it is documentation that the job was done correctly, which matters if you ever sell your home.
Any contractor doing masonry work for a fee in California must hold an active license from the California Contractors State License Board. You can verify any contractor's license on the CSLB website in minutes. We carry the required license and insurance - and we encourage you to check before you hire anyone.
These are the things that separate a repair that holds for 20 years from one that needs redoing in five. If your masonry has been showing signs of wear, the right time to address it is before Pomona's winter rains arrive - not after.

Chimneys and fireplace surrounds develop the same mortar failures as exterior walls - we handle both in the same project when needed.
