Crumbling mortar joints are the quiet start of bigger damage - water gets in, bricks start spalling, and chimneys become a safety risk. We repoint brick in San Dimas using mortar matched to your existing brick, so the repair lasts 20 to 30 years, not five.
Brick pointing in San Dimas means removing old, crumbling mortar from the joints between bricks to a depth of about three-quarters of an inch and packing in fresh mortar matched to your specific brick type, with most chimney and single-wall jobs completed in one to two days and larger exterior surfaces taking three to five days.
Mortar is designed to be the softer, sacrificial part of a brick wall - it absorbs stress from temperature swings and settling so the bricks themselves do not crack. In San Dimas, summer heat regularly above 90 degrees Fahrenheit and fall Santa Ana wind events both accelerate mortar breakdown, especially on south- and west-facing walls. Many homes in the area were built between the 1940s and 1970s, and mortar from that era is now well past its typical 25-to-30-year lifespan. Catching it before the bricks themselves start to spall is far cheaper than waiting until you need full brick replacement.
If your brick has deteriorated beyond just the mortar joints - meaning the face of bricks is chipping, flaking, or missing pieces - the repair scope expands into masonry restoration, which addresses both failed mortar and damaged masonry units in a single project.
Run your hand along the mortar joints on your chimney, planter wall, or exterior brick surface. If the mortar feels soft, crumbles when you press it, or has visible gaps wider than a credit card, it is past due. This is the clearest sign, and it is one you can check yourself in about five minutes. Open joints let water in, and water is what turns a manageable repointing job into a more expensive brick replacement.
After San Dimas's long hot summers and fall Santa Ana winds, check your chimney and exterior brick walls from the ground. White powdery streaks - called efflorescence - are salt deposits left behind when water moves through masonry and evaporates. This pattern repeats every year in the San Gabriel Valley and tends to get worse each cycle when the underlying mortar failure is not addressed.
Damp spots on interior walls near your fireplace, or water stains on the ceiling around your chimney after rain, often trace back to deteriorated mortar joints as the entry point. San Dimas gets most of its rain in short, intense winter storms - and those events are very effective at finding any gap in your masonry. Once water is inside, the damage path spreads quickly.
When mortar fails and water gets behind the brick face, the brick itself starts to break down - the surface flakes off in thin layers, a process called spalling. If you see bricks that look pitted or have pieces missing from their face, the mortar has likely been failing for a while. At this stage, repointing alone may not be enough - a mason should assess whether some bricks also need to be replaced.
We repoint chimneys, exterior brick walls, planters, retaining structures, and garden walls across San Dimas and the surrounding San Gabriel Valley. Every job starts with a careful assessment of the existing brick - we identify the type, age, and condition of the masonry before selecting a mortar mix, because using a mix that is too hard for older brick causes the bricks themselves to crack over time. That mortar-matching step is one of the clearest differences between work that lasts 25 years and work that starts failing in five. For homeowners dealing with a chimney that also needs a structural review after years of seismic activity or deferred maintenance, we often combine repointing with a foundation repair assessment to make sure no related issues are left unaddressed.
The work itself involves grinding or chiseling out the old mortar to the correct depth - roughly three-quarters of an inch - then packing in fresh mortar, tooling the joints to match the existing profile, and cleaning the brick face as we go. Most homeowners can stay in their homes throughout the project. We handle the permit question upfront - cosmetic repointing generally does not require one, but structural chimney work or wall rebuilds may, and we manage that process for you.
For homeowners with aging chimneys that need mortar restoration for water protection, seismic safety, and proper fire operation.
For homeowners with mid-century brick exterior accents, planters, or retaining features where original mortar has reached the end of its life.
For homeowners with isolated sections of failed mortar - a targeted repair that addresses the problem areas without replacing what is still sound.
For homeowners whose entire wall surface needs attention - often the right call for homes built before 1980 that have never had mortar maintenance.
San Dimas sits at the base of the San Gabriel Mountains in a seismically active region, and the combination of earthquake risk and a large stock of mid-century brick homes creates a specific set of conditions that shape how repointing should be done here. Unreinforced brick chimneys with deteriorated mortar are among the most vulnerable structures when the ground shakes - and many homes in San Dimas have chimneys that have never been inspected or repointed since they were built in the 1950s through 1970s. Restoring mortar integrity is not just a water-protection measure in this city - it is a meaningful safety step. The Brick Industry Association maintains the technical standards for repointing and mortar selection that our work follows.
We work throughout San Dimas and in neighboring cities with similar housing stock and climate conditions. In La Verne, brick chimneys and planters on older ranch-style homes are among the most frequent repointing requests we receive, often on properties where the original mortar has not been touched since the home was built. In Pomona, the mix of mid-century residential and commercial brick buildings creates consistent demand for mortar repair on both chimneys and exterior walls. Both cities face the same seasonal stress cycles - hot summers, Santa Ana winds, and winter rain - that accelerate mortar breakdown in San Dimas.
Contact us by phone or form and we will get back to you within one business day. A few basic questions - what type of structure needs work, roughly how large the area is, whether you have noticed any water inside - help us come prepared for the site visit. You do not need to know mortar types or have a diagnosis ready.
We walk the area with you, inspect the mortar joints and brick condition closely, and explain what we are seeing in plain terms. Within a few days you receive a written estimate that breaks down scope and price. This is a good time to ask questions - we will not rush you.
We confirm upfront whether your job requires a City of San Dimas permit - cosmetic repointing usually does not, but structural chimney or wall work may. Before the crew arrives, move patio furniture or plants away from the work area. If it is your chimney, close the fireplace damper and cover the firebox opening to keep dust out of your living space.
The crew grinds out old mortar, packs in fresh mortar, tools the joints, and cleans the brick face as they go. The job is noisy but does not require interior access. Fresh mortar needs 24 to 48 hours before it gets wet and about a week to reach full strength. We walk the finished work with you before we leave.
No pressure, no sales pitch. We assess the job, explain what we find, and give you a clear price in writing before any work begins.
(562) 358-3205Using a mortar that is too hard for older brick causes the bricks themselves to crack over time - a common mistake with contractors who apply a standard mix regardless of what is already there. We assess your brick before choosing a mix. That step is the single most important factor in whether your repointing lasts 5 years or 25.
In San Dimas, chimney repointing is not just about keeping water out - it is also about making sure a deteriorated chimney does not become a falling hazard when the ground moves. We treat every chimney job as both a water-protection and a structural-integrity project, because both matter in the San Gabriel Valley.
We tell you upfront whether your specific job needs a City of San Dimas permit and handle the process for you if it does. You are not left to navigate city departments on your own. Properly handled permit requirements protect you at resale and ensure the work meets local building standards.
You get a written breakdown of scope and cost before work starts. If something unexpected comes up during the job - like discovering that a section of brick is more damaged than it appeared from outside - you hear about it before it affects your bill. The California Contractors State License Board (CSLB) requires licensed contractors to operate this way, and we hold ourselves to that standard on every project.
Brick pointing is one of those repairs where doing it right once is far cheaper than doing it twice. The combination of local climate knowledge, proper mortar selection, and honest upfront pricing is what we bring to every San Dimas project.
