The foundation of your outdoor living space

A patio is the most-used feature in any backyard — and only as good as what’s underneath it. The surface is the last step; what makes it last 20 years instead of 5 is the base: proper excavation, compacted gravel, and the correct drainage slope. Ryan builds patios with no shortcuts on the prep you’ll never see.

Patio materials we install

Poured concrete

The most versatile, cost-effective option — broomed, stamped, or smooth, integrally colored or stained. With proper base prep and strategic control joints, it lasts decades.

Interlocking pavers

A modular surface that handles movement better than slab concrete — a settled section lifts and re-levels without tearing out the patio. Herringbone, running bond, and basketweave patterns, edge-restrained against shifting.

Natural flagstone

An organic, high-end look that blends with Altadena’s foothill landscape. Dry-laid on compacted gravel or mortar-set on a slab, in warm tans through blue-grays.

Decomposed granite

Budget-friendly and permeable, installed with stabilizer for a firmer surface — ideal for casual seating areas and garden paths.

What goes under your patio

The part most contractors rush: excavation to the correct depth with a compacted subgrade, 4–6” of crushed gravel compacted in 2” lifts, a minimum 1/4-inch-per-foot slope away from the house (with a channel drain where needed), and staked edge restraint so pavers don’t migrate.

Patio design for Altadena properties

Many Altadena yards slope, so a patio often pairs with a retaining wall — Ryan builds them as one integrated project so drainage and grading work together. He sizes the patio to your actual use (grill, table, afternoon shade), meets the door threshold cleanly, and combines materials — pavers, DG, flagstone — so transitions look cohesive, not bumped together.

Common questions

How much does a patio cost in Altadena?
Concrete patios run $15–$30 per square foot. Pavers cost $20–$40. Natural flagstone ranges from $25–$50. A typical 300-square-foot patio costs $4,500–$15,000 depending on material, site prep, and complexity. Ryan provides a detailed estimate after seeing your property.
What patio material is best for Altadena?
It depends on your style, budget, and use. Concrete is versatile and cost-effective — it can be stamped, stained, or broomed. Pavers offer a refined look with easy repair if a section settles. Flagstone is the premium choice with natural beauty. Ryan walks you through options on-site.
How long does patio installation take?
A standard patio takes 5–10 days from excavation to completion. Larger projects or those requiring significant grading or retaining walls take longer. Ryan provides a specific timeline with your estimate.
Do I need a permit for a patio?
In most cases, a ground-level patio in Altadena doesn't require a permit. Raised patios, patios near easements, or projects that significantly alter drainage may require one. Ryan knows the local requirements and handles permits when needed.
Will my patio crack or settle?
A properly built patio shouldn't. Cracking and settling are caused by inadequate base preparation — insufficient excavation, poor compaction, or missing gravel base. Ryan excavates to the right depth, compacts in lifts, and lays a proper gravel base before any surface material goes down.
