Crumbling mortar joints on your chimney or brick wall are a slow problem that becomes a fast one. We replace failing mortar before winter rains and seismic movement turn a maintenance job into a major repair.

Brick pointing in Simi Valley means removing old, crumbling mortar from the joints between bricks and replacing it with fresh material - most chimney jobs take one to two days, and larger wall sections run three to five days depending on size and access.
Simi Valley's housing stock skews heavily toward homes built in the 1960s through 1980s. If your home falls in that range and the brickwork has never been touched, there is a good chance the mortar is soft, cracked, or missing in spots - even if it looks okay from a distance. The trouble with waiting is that water gets in quietly and causes damage that only shows up once it is already expensive. If you have seen white staining on your brickwork or felt small cracks open after an earthquake, that is your signal to act. For homes that also need structural masonry work, our foundation repair team handles the serious structural side, and our masonry restoration service covers broader historic and decorative masonry refresh work.
Run your finger along the joints between bricks. If the mortar feels soft, sandy, or flakes away with light pressure, it is no longer doing its job. Healthy mortar should feel hard - like the brick itself. This is the clearest sign that repointing is needed.
Stand back and look at your chimney or brick wall. If you can see dark gaps where mortar used to be, water is already getting in. In Simi Valley, where winter rains can be intense and sudden, open joints like these can cause interior water damage within a single wet season.
A white, chalky residue on the face of your bricks - called efflorescence - is a sign that water is moving through the wall and carrying mineral salts to the surface. In Simi Valley's dry climate, this staining often appears after the first significant rains of the season and points to failing mortar joints.
If you noticed new cracks in your chimney or brick wall after a felt tremor or a major Santa Ana wind event, do not assume they are cosmetic. Simi Valley's seismic history and seasonal wind events make post-event inspection a smart habit for any homeowner with brick on their property.
We handle repointing for chimneys, exterior brick walls, garden planters, retaining walls, and decorative masonry features. The process is straightforward: we grind or chisel out the old mortar to the right depth, then pack in fresh material matched to your existing joints in color and profile. Getting the depth right - roughly three-quarters of an inch - is critical. Shallow removal is the most common reason repointing fails early, and it is something we never cut corners on. The Brick Industry Association publishes technical guidance on proper repointing practices that inform how we approach every job. If bricks are also spalling or cracking, our foundation repair team can assess whether the damage is structural, and our masonry restoration service handles broader repairs when more than just the joints need attention.
We also pay close attention to mortar strength matching. Using a mortar mix that is too hard for older bricks is one of the most common and damaging mistakes in this trade - it forces stress into the brick face, causing spalling that cannot be undone. We match the mortar type to the age and condition of your brickwork, so the finished work lasts and does not create a bigger problem down the road.

Simi Valley's semi-arid climate - hot, dry summers above 95 degrees followed by periodic heavy Pacific storms in winter - is hard on mortar. Joints dry out and shrink in summer, then get hit with water in winter. That cycle accelerates deterioration compared to more temperate coastal cities. On top of that, fall and winter Santa Ana wind events carry grit and debris at high speed, gradually eroding exposed mortar on chimneys and south- and west-facing walls. If your home faces the direction those winds typically come from, mortar wear tends to show up faster than on sheltered walls.
A large share of homes in Simi Valley and neighboring Moorpark were built during the 1960s through 1980s - well past the point where original mortar holds up reliably. Homeowners across Simi Valley and Camarillo have leaned on us to get ahead of deteriorating mortar before the wet season turns a maintenance job into a structural problem. We can also verify contractor credentials through the California Contractors State License Board - something every homeowner should do before hiring for any masonry work over $500.
Call or message us with a description of your chimney or wall and any damage you have noticed. We reply within one business day, ask a few questions, and schedule a site visit - no obligation.
We walk around the structure, inspect mortar joints closely, check access, and look for bricks that may need replacing. You receive a written estimate that explains what is included and what the work will cost before you agree to anything.
The crew grinds or chisels out old mortar to the correct depth, then packs in fresh mortar matched to your existing joints. You will hear grinding and tapping, and the crew contains dust as much as possible. Most chimney jobs wrap in one to two days.
Once the mortar is in, the crew cleans the brick face and removes all debris. We walk you through what was done and advise on curing time - fresh mortar needs 24 to 48 hours before it gets wet. In Simi Valley's dry heat, we may mist the joints to slow curing and prevent cracking.
Free estimate, no pressure. We reply within one business day.
(805) 261-5871We take the time to match the color, texture, and profile of your existing mortar so the finished work blends in. New mortar is lighter when it first cures, and in Simi Valley's sunny climate that weathering process happens relatively quickly - ask us about test patches for front-facing walls.
Cutting corners on removal depth - leaving less than three-quarters of an inch - is the most common reason repointing fails early. We always grind to the correct depth so the new mortar bonds properly and lasts 20 to 30 years, not two or three seasons.
Simi Valley sits near active fault systems in Ventura County, and chimneys take seismic stress hard. After any felt earthquake, we get up close and check joints and the chimney crown for damage that homeowners simply cannot see from the yard.
We have worked on homes throughout Simi Valley's older neighborhoods - the 1960s through 1980s tract homes where original mortar is now well past its useful life. That local experience means we know what to look for and how to handle the materials common to homes of that era.
The difference between a repointing job that lasts decades and one that fails in a season comes down to depth, mortar selection, and curing - all things we get right the first time so you do not have to call us back to fix it.
