JC Retrofit Construction

Secure your home against earthquakes with professional house bolting. This essential seismic upgrade attaches your home’s wooden frame directly to its concrete foundation using heavy-duty steel bolts and washers. Without bolting, your house can slide or topple off its foundation during strong ground movement—a leading cause of major structural damage.At JC Retrofit Construction, our house bolting service is tailored for older homes in Southern California that were built before modern seismic cod...

Restore your home’s balance and prevent further damage with expert house leveling. Over time, foundation settlement—caused by soil changes, poor drainage, or natural shifting—can lead to sloping floors, sticking doors, and cracks in walls. Left unaddressed, these issues worsen, affecting your home’s structural integrity and resale value.Our team at JC Retrofit Construction uses advanced techniques to lift and stabilize settled foundations. We begin with a detailed assessment using laser levels a...

When repair isn't enough, trust JC Retrofit Construction for complete foundation replacement. Aging concrete, termite damage, or poor original construction can render a foundation beyond saving. Cracks wider than a quarter-inch, sinking corners, or crumbling stem walls signal it’s time for a fresh start. Our foundation replacement service removes the old, compromised base and installs a new, code-compliant foundation designed to last decades.We manage every step: obtaining permits, safely suppor...

We are a seismic retrofit contractor serving homeowners across Southern California, where earthquake safety is a daily concern. A seismic retrofit strengthens an existing building so it holds together better during strong ground movement. Our work begins with an engineering-minded assessment of your home's structure, foundation, and weak points. From there we plan the upgrades, manage the permits, and carry the project through to final inspection. Because we live and work in the communities we s...

A soft-story retrofit reinforces buildings with open ground floors, such as garages or carports, where the lower level lacks enough walls to resist shaking. In older Southern California buildings this weakness can cause the upper floors to collapse in a major earthquake. We add structural bracing, steel moment frames, and connections that tie the floors together so the building can carry load safely. Each project starts with a careful engineering review of your property. We handle the permitting...

When a foundation has deteriorated beyond repair, replacement is often the safest path. Cracked slabs, termite damage, and crumbling stem walls are common reasons homeowners come to us. Our crew carefully supports the house on temporary beams while the old base is removed. We then pour new footings and stem walls, add proper drainage and a vapor barrier, and set anchor bolts for earthquake safety. We manage the permits and keep disruption to your household as low as we can. A free inspection wil...

House bolting secures your home's wooden frame to its concrete foundation with steel anchor bolts and washers. Older houses built before modern seismic codes can slide off their foundations during strong shaking, so this upgrade is one of the most important steps many owners can take. We inspect the crawl space and cripple walls first, then install bolts at the right spacing and add plywood shear walls where needed. Most jobs wrap up within a few days, and we handle all permits and final inspect...

Sloping floors, sticking doors, and new cracks in the walls often point to a settling foundation. We level homes by first mapping the uneven areas with laser levels, then choosing the right method for your soil and foundation. Depending on the conditions, that may mean push piers, helical piers, or mudjacking to lift the slab. Gentle work on historic homes and firmer corrections on newer houses with more severe settlement both get the same careful attention from our crew. Catching the problem ea...

Foundation problems usually show up as cracks in the walls, doors that no longer close properly, or uneven floors. We start every repair with a thorough inspection to find the cause, whether that is soil movement, poor drainage, or the age of the original footings. Depending on what we find, we may stabilize the foundation with piers, reinforce weakened sections, or correct drainage that is feeding the problem. Our crews work through the job one step at a time and keep you informed along the way...

An accessory dwelling unit, often called an ADU, is a second home on a single residential lot, such as a backyard cottage, a converted garage, or a unit attached to the main house. We build ADUs for homeowners across Southern California who want extra space for family, guests, or rental income. Our team plans the layout around your property and local requirements, then handles the structural work, foundation, and permits. We oversee each phase through final inspection so the finished unit is saf...

Seismic retrofitting adds strength to an existing structure so it can better withstand earthquake forces. Typical work includes bolting the home to its foundation, bracing cripple walls, and reinforcing connections that hold the building together. We begin with an assessment of how your home is built and where it is most vulnerable. Then we design the upgrades with our engineering partners and carry out the construction with care for your property. We manage the permits and inspections, so you c...
