Durable Paver Installation: Cool Patios & Stable Driveways

Your patio and driveway must stand up to intense Southern California sun and traffic. As the trusted paver installer Fullerton homeowners recommend, we use methods and materials that guarantee longevity and aesthetic appeal.

The Right Materials for Your Fullerton Home:

  • Cool Porcelain Paving: Ideal for patios and pool decks. It resists heat retention, making the surface comfortable for bare feet, and won’t fade under the strong OC sun.
  • Permeable Pavers: A responsible choice for driveways and walkways that helps manage stormwater runoff and maintain yard health.
  • Custom Concrete Pavers: Used for beautiful, customized driveways. We ensure the grading and base are deeply compacted and properly sealed to handle vehicles and keep the surface stable.

Every project starts with expert ground preparation to guarantee your pavers remain level and durable for decades.

Retaining Walls: Protect Your Land & Create Usable Space

If your property has slopes, a retaining wall is necessary to prevent erosion and create flat, usable areas for new patios or garden beds. We build walls that are structurally guaranteed and beautifully finished.

Our structural expertise ensures your wall is safe and compliant:

    • Structural Design: We manage the necessary engineering and permits for walls over four feet, guaranteeing long-term stability.
    • Material Solutions: We use decorative segmental blocks for landscaping features or reinforced poured concrete for critical hillside support, such as stabilizing a foundation area for a new ADU.

Secure Your Property: Fence Installation & Automatic Gates

A high-quality fence is essential for privacy and security. As the premier fence company Fullerton offers, we guide you through material selection and ensure full compliance with neighborhood fence code restrictions.

We provide durable solutions, including vinyl, wood privacy, metal fencing, and custom automatic driveway gates for enhanced security and convenience.

Custom Decks and Patio Covers: Your Shaded Oasis

 Maximize your outdoor entertainment space with a custom deck or a permanent shade structure. As a trusted deck builder Fullerton, we specialize in low-maintenance materials like composite decking that resist weathering and sun damage.

Fullerton Deck & Shade Specialties:

  • Decks: Custom composite or wood decks, perfect for outdoor sectionals and dining areas.
  •  Patio Covers: Permanent shade solutions, including aluminum lattice, insulated covers, and solid roof extension, providing essential relief from the summer heat.

We ensure all deck and patio covers Fullerton installations are secured properly to handle wind and comply with local fire safety codes.

The "But, What About...?" Section

What materials do you recommend for deck builders in Fullerton to prevent warping and dry-rot from the heat?

We strongly recommend high-performance composite decking (not wood) for all deck builder Fullerton projects. Composite resists warping, sun damage, and dry-rot, making it the most durable, low-maintenance option for the Orange County climate. 

Yes. Properties in historic districts or specific community zones often have unique requirements for fence materials, height, and setbacks. As your local fence company Fullerton, we handle the specific architectural review process required for your location. 

All of our paver patio installations carry a comprehensive 3-year labor warranty against settling, shifting, and drainage issues. We also guarantee the manufacturer’s warranty on the stone itself, providing complete protection for your hardscape investment. 

Yes, absolutely. While our main focus is structural, we offer design consulting for integrating built-in BBQs, storage, and counters into your new patio or deck paver space. We ensure the base and utility lines are correctly engineered for the appliance you choose.

We engineer retaining walls to improve drainage. Our process includes installing a crushed rock base and French drains behind the wall to redirect water safely away from your foundation and prevent soil saturation, protecting your yard and home.

Usually, yes. New, detached ADUs typically require the installation of separate utility connections, including water, power, and sewer lateral connections. We manage the detailed utility excavation and hookup coordination with the City of Fullerton during the construction phase.

Once your Fullerton ADU permits are secured (which we manage), most standard garage conversions or small detached builds are completed in approximately 3.5 to 5 months. New construction builds may take longer.
