50 Years in Los Angeles

A Private Firm Built on Long-Term Relationships

MDM General Contractor is a privately owned, Los Angeles-based firm with more than five decades of experience in residential and commercial construction. Founded on the principle that quality work speaks for itself, MDM has grown from a small remodeling operation into a full-service construction company with an award-winning management team and over $200 million in developed properties across the greater Los Angeles market.

We specialize in complete design, build, and materials selection services, which means our clients work with one team from concept through certificate of occupancy. That continuity produces better buildings, fewer delays, and a finished product that reflects exactly what the client envisioned at the start. With a 5.0 Google rating earned across 39 verified reviews, our track record in Los Angeles neighborhoods from Silver Lake to Brentwood to Culver City speaks louder than any marketing claim.

Established 1974

"We built this company on a simple idea: if you treat every project like it's your own home, the work takes care of itself. Fifty years later, that hasn't changed. The clients who trust us with their biggest investment deserve a contractor who takes that responsibility seriously, every single day."

What We Stand For

Our Core Values

These aren't slogans printed on a wall. They're the standards our crew is held to on every Los Angeles job site, every day.

Craftsmanship Without Compromise

Every cut, every joint, every finish is held to the same standard regardless of the project budget. We don't have a separate crew for premium clients. Every MDM client gets our best work.

Total Transparency

We provide fixed-price quotes in writing before any work begins. If something unexpected comes up during construction, we explain it clearly and get your approval before proceeding. No surprises on the final invoice.

Built to Code. Built to Last.

Every MDM project is fully permitted through the City of Los Angeles and passes all required inspections before we call a job complete. Permitted work protects your investment and makes your property easier to sell.
