What Is the Patio Installation Process?
Our patio installation process follows six stages — consultation and design, excavation, base preparation, material installation, drainage integration, and finishing — completed in that order to prevent the shifting, pooling, and cracking common with rushed installations.
- On-Site Consultation & 3D Design — We measure yard elevations, assess drainage flow, and build a design around your budget and style before any digging begins.
- Excavation & Foundation Prep — We excavate to the correct depth for your chosen material and compact a reinforced gravel base — a step many competitors shorten to save time, which is the leading cause of patio settling.
- Material Installation — Pavers, concrete, or stone are installed following ICPI and engineering guidelines for alignment, spacing, and slope.
- Drainage System Integration — Water is directed away from your home’s foundation to prevent erosion, pooling, and long-term shifting.
- Edge Restraints & Final Compaction — Restraints lock the patio system in place so edges don’t spread or separate over time.
- Joint Sanding, Sealing & Clean Finish — Optional sealing protects against stains, fading, and weather damage, and can extend the life of the surface significantly.
With this process, a properly installed patio in St. Louis should perform well for decades rather than needing repair within the first few years.
Why Choose STL Retaining Wall Install Pros for Your Patio?
STL Retaining Wall Install Pros is a licensed, insured, ICPI/NCMA-certified hardscaping company serving the St. Louis metro area, with a 100% workmanship guarantee on every patio, retaining wall, and drainage system installed.
Qualifications
Our installers are trained in base preparation, geogrid reinforcement, and drainage design, and every project is built to meet or exceed St. Louis engineering and building code requirements. This matters for patios specifically because Missouri’s freeze-thaw cycles cause poorly built patios to crack, heave, or settle unevenly within just a few years — proper certification-backed technique is what prevents that.
Capabilities
We handle every phase in-house: design, excavation, drainage engineering, material installation, and finishing. Our capabilities cover paver systems, poured and stamped concrete, natural stone, segmental hardscape structures, and integration with outdoor living construction like kitchens, pergolas, and fire features — so your patio isn’t a standalone slab but part of a cohesive backyard plan.
Commitments
We guarantee our craftsmanship 100%, communicate clearly through every phase, and show up on schedule. If a patio settles, drains poorly, or shifts due to installation error within the warranty period, we make it right at no cost to you.

What Factors Affect Patio Installation Cost?
Patio cost is driven primarily by material choice, patio size, site accessibility, base depth requirements, and design complexity such as curves, multiple levels, or integrated features like fire pits and seating walls. Sloped yards, poor existing drainage, or rock/clay-heavy soil (common in parts of the St. Louis metro) can also increase excavation costs.

What Types of Patios Can You Install in St. Louis?
St. Louis homeowners can choose from paver, concrete, natural stone/flagstone, or brick patios — each offering different combinations of cost, durability, and style — and all can be combined with custom features like fire pits, seating walls, and covers.
Paver Patio Installation
A paver patio is built from interlocking brick, concrete, or natural stone-blend pavers set on a compacted base, offering slip resistance and easy spot-repair if a single paver is ever damaged.
Pavers are the most popular choice for St. Louis backyards because individual units flex independently with ground movement instead of cracking as one solid piece — a major advantage during Missouri’s freeze-thaw winters. They’re available in dozens of colors and patterns, from herringbone to running bond, and can be matched to existing driveway or walkway pavers for a cohesive look.
Concrete Patio Installation
A concrete patio is a poured, monolithic slab finished as standard broom-finish, stained, or stamped decorative concrete, and it’s typically the most budget-friendly full-coverage patio option.
Stamped concrete can mimic the look of natural stone, brick, or wood at a fraction of the material cost, making it a popular option for larger entertaining areas, grilling patios, and pool decks. Because it’s poured as a single slab, proper control-joint placement and base compaction are critical to prevent cracking — something our crews plan for during the design phase, not after installation.
Natural Stone & Flagstone Patio Installation
A natural stone or flagstone patio uses irregular or cut slabs of bluestone, limestone, flagstone, or slate, delivering the most authentic, high-end look of any patio material.
These patios suit garden-style backyards, historic St. Louis homes, and clients who want a one-of-a-kind surface where no two stones are identical. Natural stone is heavier and requires deeper base preparation than pavers or concrete, but it’s also among the most durable materials available, often outlasting the home itself with minimal maintenance.
Brick Patio Installation
A brick patio uses clay or concrete brick units laid in classic patterns like basketweave or herringbone, complementing the traditional architecture found throughout St. Louis’s historic neighborhoods.
Brick is a strong match for homes in areas like Clayton, Ladue, and Kirkwood where classic architectural styles are common, and it holds color well over time compared to some dyed concrete products.
Custom Patio Design & Build
A custom patio integrates additional hardscape and outdoor living elements — retaining walls, seating walls, outdoor kitchens, pergolas, fire features, and lighting — into a single connected backyard design.
Rather than installing a standalone slab, we design full outdoor living environments where the patio, walkways, and structural elements work together both functionally and visually.
Patio Door, Cover & Enclosure Installation
Patio door, cover, and enclosure installation extends your outdoor space into a weather-protected, year-round living area, including sliding or hinged doors, roofed covers, and screened enclosures.
This service includes:
- Sliding and hinged patio door installation
- Vinyl patio door replacement
- Patio cover and roof installation
- Screen and enclosure installation for bug- and weather-protection
Adding a cover or enclosure typically extends usable patio time in St. Louis by several additional months per year, especially during the region’s humid summers and unpredictable spring rain.
Can You Install a Patio on a Sloped or Uneven Yard?
Yes — sloped or uneven yards can be leveled through grading, terracing, or retaining wall integration, making them just as suitable for patio installation as flat yards.
Many St. Louis properties, particularly in hillier suburbs, have grade changes that require additional planning. We address this by combining patio installation with retaining wall construction or multi-level terracing, which also improves drainage on properties where water previously pooled near the home.
How Long Does Patio Installation Take in St. Louis?
Most patio installations in St. Louis are completed within 3 to 7 days, depending on patio size, material choice, and weather conditions.
Larger patios, natural stone installations, or projects that include retaining walls, fire features, or outdoor kitchens typically take longer due to additional excavation, structural work, and curing time (for concrete or mortared stone).
