Synthetic Turf Installation: Step-by-Step, Costs, DIY vs Pro
Patchy grass, muddy spots, and rising water bills can make a natural lawn feel like a full-time job. If you’re eyeing synthetic turf to save water and weekend hours, you’re not alone—but getting it wrong leads to wrinkles, poor drainage, bad seams, and odors. A smart plan prevents costly do-overs.
The good news: with proper base preparation, drainage, and the right turf and infill, a synthetic lawn can look natural, drain quickly, and stand up to kids and pets. This synthetic turf installation guide translates pro methods into clear, doable steps and shows where it pays to hire a specialist.
Inside, you’ll get a step-by-step plan: measure and choose turf, confirm HOA/permits and call 811, design drainage, excavate and build the base, compact, seam, anchor, add infill, and groom. We’ll list tools and materials, break down costs (with Orange County examples), compare DIY vs pro, flag common mistakes, and outline maintenance. Ready?
Step 1. Plan your project, measure the area, and select the right turf
Start with a scale sketch of your space and a clear goal (water‑saving lawn, pet area, putting green). Accurate measurements and a smart roll layout cut seams, waste, and cost during synthetic turf installation.
Step 2. Check HOA rules, permits, and call 811 to mark utilities
Before you swing a shovel, confirm HOA rules and city requirements for synthetic turf installation. Some HOAs limit artificial grass or specify approved products; secure written approval. Ask your city whether permits apply for excavation depth, grading, or new drainage. Finally, call 811 at least a few days before you dig so utilities are marked and you can plan safe excavation.
Step 3. Assess irrigation and design a drainage strategy
Water that can’t escape will ruin even the best synthetic turf installation. Start by locating all sprinkler heads, valves, and drip lines in the work area, shutting the zone off, and capping or removing any irrigation under the future turf. Then plan how water will move: your base should shed water with a gentle 2% slope and no low spots, using free‑draining aggregate to move runoff away from structures.
Step 4. Gather tools, safety gear, and materials
Have everything on site before you break ground—delays wreck compaction. For a smooth synthetic turf installation, bring a shovel and wheelbarrow, a tamper or rented plate compactor, a utility knife, seaming tape and outdoor adhesive, galvanized nails, road base or crushed stone, silica sand (or zeolite for pets), and basic PPE: gloves, goggles, knee pads.
Step 5. Remove existing lawn and excavate to the proper depth
Strip all existing grass, roots, mulch, and organic debris down to clean subgrade—never lay turf over living grass, which causes drainage and weed issues. Excavate 2.5–4 inches to accommodate a free‑draining aggregate base (per pro guidance and retailer specs) and rough in about a 2% slope for runoff. Haul away sod and roots to prevent regrowth, and work carefully around previously marked utilities.
Step 6. Install edging and optional gopher wire for perimeter stability
Create a solid frame so the base and turf stay put. Install metal edging or bender board (2x4 or 1x4) around the footprint, especially along fences, beds, and curves. It separates turf from planters, contains aggregate, and gives nails a firm bite. In gopher‑prone areas, lay gopher wire on subgrade and run it up the sides to form a cage before the base goes in.
Step 7. Place weed barrier where appropriate
A permeable weed barrier can reduce weed pressure while letting water pass—use it where soil is “alive” or prone to intrusion. You can lay it on the excavated subgrade before the aggregate base, or place it between base layers (both methods are used by pros). Overlap seams, face the correct side up, and secure with 6-inch galvanized nails or landscape anchors every few feet. Note: some installers skip fabric to avoid bacteria buildup and instead apply a pre-emergent plus a well-compacted base—especially for pet-heavy areas.
Step 8. Build the base with class II road base or crushed stone
Your turf only performs as well as its foundation. Install a free‑draining base using Class II road base (3/4-inch minus) or similar crushed stone. Place 2–4 inches total depth, spreading in even lifts and keeping aggregate cleanly inside your edging. Maintain the rough 2% fall you planned so water has a path out. For a glass‑smooth finish, you may add a thin cap (up to ~1 inch) of decomposed granite over the road base—never use DG by itself, as it doesn’t hold nails.
Step 9. Grade for drainage and compact the base thoroughly
With the aggregate placed, set final grade for drainage and lock it in with thorough compaction. Maintain about a 2% fall away from structures, screeding to erase dips. Lightly mist the base and compact in thin lifts—use a plate compactor for uniform density; hand tamp only in tight corners.
Step 10. Roll out and acclimate turf; align the grain for a natural look
Set turf rolls in direct sun for 1–2 hours with blades facing down to relax curl and make handling easier. During synthetic turf installation, carry and unroll pieces gently over the compacted base—don’t drag and disturb your grade. Rough-position each roll square to your main sightline (patio, doors) for the best visual.
Step 11. Cut to fit and dry-fit the layout before seaming
With the turf relaxed, flip edges up and cut from the backing with a sharp utility/turf knife. Trim off the factory edge by cutting about three stitch rows to create clean, matchable seam edges. Rough-cut pieces slightly oversize; scribe to borders and trim flush later. Dry-fit all rolls for your synthetic turf installation with the grain aligned, maintain a consistent ~1/8-inch gap along seam lines, and temporarily tack corners so nothing shifts before you seam for good.
Step 12. Seam turf rolls with tape and adhesive the pro way
After dry-fitting, fold both edges back and center seaming tape beneath the joint. Trowel a thin, even coat of outdoor turf adhesive on the tape—light enough that glue won’t bleed through drain holes. Set both edges down with a consistent ~1/8-inch gap, align blade direction, and work the fibers so none are trapped in the glue. Use a carpet kicker to close the seam, brush the fibers up, weight with sandbags, and allow to cure per the adhesive manufacturer.
Step 13. Secure the perimeter with nails or landscape anchors
Stretch the turf taut and fasten the perimeter with 5–6 inch hot-dipped galvanized nails or landscape anchors spaced about every 3–4 inches. Set heads flush—never countersink—and keep fibers clear of the fasteners. Reinforce corners, curves, and high-traffic edges. Finally, trim any overhang clean and tight to the edging.
Step 14. Add infill and power-broom to lift fibers
Evenly top‑dress the turf with infill using a broadcast or drop spreader. Plan roughly 1.5–2 lb per sq ft, choosing silica sand for lawns or zeolite-based infill for pet odor control. Power broom or stiff‑broom the surface to work material down between fibers and lift the pile. Add a bit extra along outer edges for weight. Avoid regular masonry sand or metal rakes.
Step 15. Final rinse, grooming, and quality checklist
Finish with a light hose rinse to settle dust and reveal any low infill or high spots. Power broom in overlapping passes, then make a final groom with the grain. This resets pile height, distributes infill, and exposes wrinkles or gaps to correct before sign‑off.
Tools and materials checklist
Staging your gear before demolition keeps the build moving and helps you compact in the same day. Rent the plate compactor in advance, and wear gloves, eye protection, and knee pads. Use this concise checklist most pro installs rely on.
Cost breakdown: materials, labor, and typical add-ons
Budget smart: pro synthetic turf installation costs are driven by materials, labor, operations, overhead, and profit. Smaller projects cost more per square foot; 500 sq ft jobs price higher than 2,000 sq ft, which trend near the low end.
Pet-friendly infills, drainage upgrades, putting greens, padding, and premium edging are common add-ons that increase price.
Local pricing: synthetic turf installation cost in Orange County, CA
Orange County pricing generally tracks California averages for synthetic turf installation. Expect about $9–$15 per sq ft installed, with smaller areas costing more per square foot. Big‑box quotes often land around $8–$12 per sq ft before upgrades. Typical CA-based totals:
Project sizeEstimated totalApprox $/sq ft500 sq ft$7,350$14.701,000 sq ft$12,360$12.401,500 sq ft$15,750$10.502,000 sq ft$19,200$9.00
Cost factors that raise or lower your price
Two same-size lawns can price very differently. Installers bid synthetic turf installation on scope, difficulty, and risk—not just turf cost. The levers below most often move your number in Orange County, and several are choices you control during planning and design.
DIY budget vs pro pricing: sample scenarios and total cost ranges
Here’s how budgets typically shake out for synthetic turf installation. DIY is largely materials-driven, while pro pricing folds in excavation, base prep, crew labor, delivery/hauling, overhead, and warranty. Smaller projects run higher per square foot; bigger footprints benefit from economies of scale.
Note: Pet systems, premium edging, drainage upgrades, padding, or putting greens increase totals.
DIY vs pro: when to handle it yourself and when to hire
If you’re handy, patient, and can excavate 2–4 inches, compact thoroughly, and execute tape‑and‑glue seams, a small, simple rectangle with good access can be DIY‑friendly. Plan a ~2% slope, rent a plate compactor, and stage materials so base prep and turf placement happen the same day.
How to choose a professional installer in Orange County
Shortlist licensed, insured OC contractors with recent, local installs you can see. Ask for a written scope that spells out the technicals: 2–4 in of Class II base, ~90% compaction, ~2% drainage grade, tape‑and‑glue seams, perimeter nails every 3–4 in, seam nails ~4 in, and 1.5–2 lb/sq ft infill. Confirm they cap irrigation, handle HOA/permit coordination and 811, price hauling/delivery transparently, offer workmanship/material warranties, and have proven pet systems and putting‑green expertise (no perimeter nails on greens).
Common mistakes to avoid during installation
Even skilled DIYers trip on a few predictable pitfalls. Avoid these and your synthetic turf installation will drain well, look seamless, and last. Most problems come from rushed base prep and seams—where drainage, stability, and a natural, uniform finish are won or lost.
Special installations: pet-friendly turf, putting greens, and play areas
Some projects need tweaks beyond a standard synthetic turf installation. If you’re building for pets, practicing your short game, or cushioning a kids’ zone, adjust materials and methods for performance and safety.
Project timeline: how long installation takes and what can delay it
With a pro crew, most 500–1,000 sq ft lawns wrap in 1–2 workdays: base prep, then turf, seams, and infill. Crews can place roughly 700 sq ft per day when access and weather cooperate. DIYers should budget a full weekend for simple layouts.
Maintenance and care schedule after installation
A little routine keeps synthetic turf looking fresh, draining well, and odor-free. Think light, regular touch‑ups: remove debris, rinse, and brush the fibers back up. Use a stiff‑bristle or power broom, plastic rake (not metal), and a garden hose. Skip harsh chemicals; follow your turf manufacturer’s guidance.
What do you put under synthetic turf?
Under synthetic turf, you need a free‑draining, compacted foundation. Pros install 2–4 inches of Class II road base or similar crushed stone, shaped to about a 2% slope so water sheds away. A thin decomposed granite cap can be added for a smoother finish, but never use DG as the only base since it doesn’t hold nails. Depending on conditions, add a permeable weed barrier (optional) and gopher wire in problem areas, and frame the perimeter with edging to contain the base and secure the turf.
How do you prepare ground for synthetic turf?
Ground prep is where a synthetic turf installation succeeds or fails. Work clean, control drainage, and compact thoroughly so the surface stays flat and drains fast.
What base do you put under artificial turf?
Use a free‑draining, compacted aggregate base—typically 2–4 inches of Class II road base (3/4-inch minus) or similar crushed stone. Shape it to about a 2% slope for runoff and compact to a firm, uniform surface. You may add a thin decomposed granite cap for smoothness, but never use DG alone; it doesn’t hold nails and can shift when wet. Avoid mixing base with native soil.
Permits, HOAs, and city guidelines you should know
Rules vary across Orange County. Before you dig, secure written HOA approval and verify city requirements—some HOAs don’t allow synthetic grass, others require specific products and installation methods. Cities may require permits if you alter grade, add drainage components, or haul significant soil. Always call 811 a few days before excavation.
Key takeaways and next steps
A great synthetic lawn starts with drainage and a solid base. Plan carefully, then execute methodically—excavate, build and compact the base, align, seam, anchor, and infill—for a clean, natural look that drains fast and lasts.
