Turf Removal & Replacement in Seattle, WA | Tear-Outs & Lawn Conversions

Seattle's steep, forested yards present a unique challenge: mature Douglas firs and western red cedars shade out lawn grass, while heavy winter rains turn exposed soil to mud. When a real lawn fails under the canopy or in compacted clay, many homeowners turn to turf removal, replacement and lawn conversion to reclaim usable outdoor space. We remove old turf, prepare the base properly, and install synthetic grass that drains, stays green year-round, and handles Seattle's wet winters without turning to moss. Whether you're replacing a failed natural lawn, converting a muddy slope, or switching from one artificial turf product to a better one, we handle the entire process with written specifications and local expertise.

Why Turf Removal and Replacement Matter in Seattle's Wet Climate

Seattle's long grey winters and shallow root zones make natural grass a losing battle in most residential yards. Moss colonizes thin turf under fir shade, clay-heavy soils hold standing water, and compacted ground from decades of foot traffic blocks drainage. Rather than fight the climate year after year, lawn conversion to artificial turf eliminates the cycle of seeding, fertilizing, and watching grass die back each season. Removal and replacement also solve the problem of old, worn turf that has flattened, faded, or developed seams and drainage failures.

• We extract old turf completely, including any matted backing and infill that no longer performs.
• We grade and compact a proper base using crushed stone and geotextile to handle Puget Sound rainfall without pooling.
• We install new turf with face weight, pile height, and infill rated for your specific use and Seattle's moisture.
• We ensure seams are sealed and edges are finished so turf stays in place on slopes and around structures.

A complete removal and replacement job gives you a fresh foundation, not a patch over a failing system.

Key info: Many Seattle homeowners discover that old artificial turf installed in the 2000s or early 2010s has failed because the base was laid on bare dirt or poor drainage, or because the turf itself was low-grade. Proper removal and base prep prevent that mistake the second time around. See our pricing overview for realistic costs on removal and replacement in your area.

How We Remove Old Turf and Prepare Your Yard for Conversion

Removal and replacement is not a one-day job. We start by marking utility lines (irrigation, low-voltage lighting, pet fencing) so we do not damage what is buried. We then extract the old turf, backing, and infill down to native soil, haul it away, and evaluate drainage. If water pools or the soil is compacted clay, we grade to slope away from structures and install a base of crushed stone, proper geotextile, and compaction to meet local stormwater expectations. Only then do we measure, order, and install new turf.

• We request a Washington 811 utility locate before any excavation to mark public lines, though private irrigation and pet fences are your responsibility to mark.
• We remove all old turf, backing, and infill and haul the debris off site.
• We evaluate soil compaction and drainage, and correct grading or base problems that caused the original failure.
• We install new base at the proper depth, typically 4 to 6 inches of compacted crushed stone with geotextile, depending on site conditions.
• We measure the yard, order turf to spec, and install with sealed seams and finished edges.

This step-by-step approach ensures the new turf does not fail for the same reasons the old one did.

Local example: A Queen Anne homeowner had moss-covered, thin natural grass under a large Douglas fir. We removed the old sod, graded the yard to improve drainage away from the house, installed a 5-inch compacted base with geotextile, and laid 65-ounce, 2.5-inch pile turf rated for shade and heavy moisture. The yard now stays green and dry in winter, and the homeowner no longer spends spring cleaning out dead patches.

Removal and Replacement Methods for Seattle Yards

Different yards demand different approaches. A small, level patio conversion is straightforward. A steep, tree-filled slope with old turf and compacted soil requires grading, amended base, and careful edge work. Commercial properties and multi-unit buildings may involve coordination with property managers and inspection by the city. We match method to site conditions and document the work in writing.

Turf Removal, Replacement and Lawn Conversion Cost in Seattle: What to Expect

Removal and base prep typically start at $2 per square foot and range up to $4 to $5 per square foot depending on site conditions. A 400-square-foot patio conversion with good drainage might cost $800 to $1,200 for removal and base. A 1,000-square-foot sloped yard with clay compaction and drainage correction could run $3,000 to $5,000 for removal, grading, and base work alone. New turf installation is priced separately. The biggest cost drivers are soil compaction, slope grade correction, and whether drainage work is needed.

• Removal of old turf, backing, and infill typically costs $1 to $2 per square foot depending on how much material is present.
• Grading and base prep (crushed stone, geotextile, compaction) adds $1 to $3 per square foot based on slope and soil condition.
• Drainage correction (regrading, French drain, amended base) adds $1 to $2 per square foot if the site pools water.
• New turf installation is estimated separately and depends on product grade, face weight, infill, and seaming complexity.
• Hauling and debris removal are included in removal pricing.

Every yard is different. We recommend getting 2 to 3 written estimates that break down removal, base prep, and new turf costs separately so you understand what drives the price. See our full pricing page for more detail on typical costs across Seattle and surrounding areas.

What to Look for When Hiring a Turf Installation Company Near Seattle

Not every crew that removes old turf and lays new grass will do the job right. Many outfits strip the old material, dump it on bare soil, and lay 40-ounce turf without proper base or sealing. Six months later, the turf is lifting, seams are opening, and drainage is failing. When you call for an estimate, ask the right questions and verify the company's approach before you hire.

• Ask for a certificate of insurance naming general liability and workers' compensation, and verify it is current and covers the scope of work.
• Request a written specification that names the turf product, face weight, pile height, infill type and pounds per square foot, and base depth and compaction method.
• Ask whether the company will request a Washington 811 utility locate and mark private lines (irrigation, pet fence, low-voltage) before excavation.
• Check references and photos of finished removal and replacement jobs, and ask how long the work has lasted.
• If your property is in an HOA, confirm the company understands architectural rules and can help with submittals for approval.
• Verify the company has a local address and is reachable by phone during and after the job.

A professional turf installation company will answer every one of these questions clearly and provide written documentation.
