Built With Honor. Delivered With Quality.

At Alexander Constructions Co. INC, our mission is to deliver high-quality, full-service construction solutions that homeowners and businesses can rely on. As a 100% service-disabled veteran-owned company, we approach every project with discipline, integrity, and unwavering attention to detail.

From initial planning and construction to electrical, plumbing, finishing work, and final cleaning, we are committed to providing a turnkey experience that makes every project seamless and stress-free. We believe in building trust through transparent communication, craftsmanship that stands the test of time, and a standard of quality that never wavers — no matter the size of the job.

Full Residential & Commercial Construction

Whether constructing a custom home, upgrading a commercial space, or completing a major addition, our team delivers reliable, code-compliant building services tailored to your project’s needs. As a veteran-owned contractor, we combine discipline, skill, and quality craftsmanship to ensure every structure is built to last.

Custom Home Construction

We specialize in building fully customized homes designed to match your lifestyle, architectural preferences, and long-term goals. Our team manages every phase — permitting, foundation, framing, electrical, plumbing, finishing, and final walkthrough — ensuring a seamless and stress-free experience. With unwavering attention to detail, we create homes that are efficient, durable, and crafted with the highest standards of quality.

Room Additions & Extensions

Whether expanding your living space, adding bedrooms, or extending common areas, we design and build additions that blend seamlessly with your existing structure. Our additions focus on structural integrity, aesthetic continuity, and enhanced functionality. From foundation to roofing to finishing details, we ensure your new space looks and feels like it has always been part of your home.

Commercial Tenant Improvements

We offer complete build-outs and upgrades for offices, retail spaces, and small commercial environments. Our team focuses on efficiency, compliance, and long-term durability, ensuring your space supports operations, safety requirements, and customer flow. From layout configuration to full mechanical and electrical systems, we prepare your business for success.

Electrical Services

Electrical work requires precision, safety, and expert knowledge — and we bring all three to every project. Whether upgrading outdated systems or installing new components, we ensure your electrical infrastructure is safe, efficient, and ready for modern demands.

Panel Upgrades

We replace outdated or overloaded electrical panels with modern systems capable of supporting today’s high-demand appliances, smart technology, and home expansions. Our installations reduce fire risk, improve power distribution, and ensure your system meets current building codes, providing reliable power for decades to come.

Wiring & Rewiring

Old or damaged wiring can create serious safety hazards. We remove outdated or unsafe wiring and install modern, grounded, code-compliant systems designed for long-term performance. Whether upgrading a single area or rewiring an entire home, we deliver clean, efficient installations that enhance safety and reliability.

New Circuit Installation

Appliances, lighting, and workshops, we design and install dedicated circuits to eliminate overloads and ensure consistent power flow. Every circuit is properly rated, protected, and tested for maximum safety and efficiency.

Plumbing Services

As a full-service general contractor, we provide complete plumbing solutions integrated directly into your construction, renovation, or expansion project. Our team ensures all plumbing systems are installed correctly during the building process, following code, coordinating with electrical/structural phases, and delivering seamless functionality from day one. No need to hire separate subcontractors — we handle it all in-house for a smoother, faster, turnkey experience.

Construction-Integrated Plumbing Installation

During new builds, additions, and remodels, we install all essential plumbing lines, drains, vents, and water connections needed for long-term durability and performance. Our team works in coordination with framing, electrical, and finishing phases to ensure every pipe is properly placed and fully compliant with building codes. From kitchen water lines to bathroom drains to utility hookups, we ensure every system is built right the first time.

Turnkey Post-Construction Cleaning

Rough Cleaning (During Construction)

We handle job-site clearing, sweeping, dust removal, and debris management throughout the construction process to maintain a safe, organized work environment. Rough cleaning keeps progress efficient and reduces hazards for workers and homeowners.

Final Cleaning (Turnkey Ready)

Once construction is complete, our team performs deep cleaning of floors, fixtures, surfaces, windows, and hard-to-reach areas. This ensures your space looks polished, fresh, and move-in ready, showcasing the quality of the finished work.

Exterior Job-Site Cleanup

We clear landscaping areas, pathways, entryways, and outdoor surfaces of dust, debris, and materials left from construction. Your property is delivered completely clean inside and out, ready for viewing or immediate use.

Based in Orange County, we offer our full-service construction and remodeling capabilities across Long Beach, Los Angeles, Riverside, Inland Empire, Ventura, Santa Barbara, and surrounding areas.
