This guide compares artificial grass, natural sod, and real grass for Seattle yards, and explains how to read a turf specification so you can compare quotes fairly. It is written for homeowners in Seattle and surrounding areas who are deciding whether synthetic turf is right for their yard, or who want to understand what they are buying before installation.
The vocabulary around turf can be confusing: the word 'turf' is used for both natural sod and synthetic grass, while 'artificial grass', 'synthetic turf', and 'artificial turf' all name the same product. This guide sorts the terms, explains how each option handles Seattle's wet winters and shaded yards, and shows you what to ask for in writing so you can compare installers on the same terms.
Turf vs Artificial Grass: Is There a Difference?
The confusion starts with the word 'turf' itself. In everyday speech, 'turf' can mean either rolls of natural sod (living grass) or synthetic turf (plastic grass). To avoid mixing them up, this guide uses 'real grass' or 'natural sod' for living grass, and 'artificial grass', 'synthetic turf', or 'artificial turf' for the plastic product. They are completely different materials with different installation methods, costs, and maintenance routines.
Artificial grass and sports turf are also built differently from each other, even though both are synthetic. Landscape artificial grass, used in residential yards, is designed to look natural and feel soft underfoot. It has a softer fiber, a longer pile (the visible blade length), and a lighter face weight (density). Sports turf and putting green turf are engineered for specific performance: a putting green uses a shorter, denser pile and a shaped base to hold a consistent roll; playground turf includes extra cushioning to meet safety standards; and dog turf prioritizes drainage and antimicrobial properties. The right product depends on what the yard will be used for, not on price alone.
Artificial Grass vs Real Grass in Seattle: An Honest Comparison
In Seattle, a real lawn faces a hard climate. Winters are long, wet, and grey; the soil is glacial till and clay that holds water; and many yards sit under tall Douglas firs and western red cedars that block sunlight and drop needles year-round. A lawn in deep shade will thin out, moss will take over, and the soil will stay damp even in summer. A lawn in full sun can work, but only if drainage is good and you are willing to water through the dry season and overseed in fall. Real grass requires regular mowing, fertilizing, aeration, and weeding. It looks good for part of the year and thins or goes dormant in others. It will die under a dog run or in a high-traffic area. It costs nothing to install but requires ongoing care and water.
Artificial grass is low-maintenance, not maintenance-free. It needs occasional rinsing to remove dust and pollen, brushing to restore the pile if it gets matted, and infill top-up every few years as the infill settles or is displaced. It does not require mowing, fertilizing, or watering. It stays green year-round and handles dogs, kids, and heavy foot traffic without wearing thin. It works in full sun and in shade. The trade-off is the upfront cost and the fact that it will eventually need replacement (typically 15 to 20 years depending on use and climate). Real grass still makes sense if you have a shaded yard where a healthy lawn can grow, if your budget is very tight, if your HOA requires living grass, or if you enjoy the work of lawn care. Otherwise, artificial grass is usually the better answer for Seattle yards.
Turf vs Sod: When Natural Sod Is the Better Answer
Natural sod is rolls of living grass, grown in a nursery and laid like carpet. It establishes faster than seed and gives you an instant lawn. Sod works well on a small budget (lower upfront cost than artificial grass), in a yard with real shade where a healthy lawn can grow, or where an HOA requires living plants. However, sod still requires the same ongoing care as a seeded lawn: watering, mowing, fertilizing, and overseeding. In Seattle's wet climate, sod will struggle on a yard with poor drainage or deep shade, and it will not survive under a dog run or in a high-traffic area.
We install artificial grass and do not install natural sod. That means we will sometimes tell you that sod is the better answer, because it is. If your yard is in real shade and you are willing to water and maintain a lawn, sod from a local nursery may cost less upfront and suit your needs better. If your yard is sunny and well-drained, or if you have dogs or kids who will wear it out, or if you want a yard that is ready to use year-round without mowing, artificial grass is the right choice. Honest advice means saying which one fits your situation, not just selling the one we install.
Polyethylene vs Nylon vs Polypropylene Artificial Grass
Artificial grass fibers come in three main types: polyethylene, nylon, and polypropylene. Each has different properties, and the fiber type determines how the turf will perform and how long it will last. Polyethylene is the landscape standard for residential yards. It is soft, has a natural appearance, and holds color well in sunlight. It is less heat-resistant than nylon, so it can get warm in full sun, but it is durable enough for most residential uses and is the most common fiber in mid-range turf products. Nylon is the most resilient and heat-tolerant fiber available. It is stiffer than polyethylene, so it does not feel quite as soft underfoot, but it recovers from compression better and lasts longer under heavy traffic. Nylon is typically used on putting greens, sports fields, and high-traffic commercial areas, and it usually costs more. Polypropylene is the budget fiber. It is the least durable of the three, fades faster in sunlight, and does not bounce back from compression well. It is common in very cheap roll products sold online or at big-box stores, and it is rarely the best choice for a permanent installation.
The fiber alone does not tell you whether a turf is good or bad. A high-quality polyethylene turf will outperform a cheap nylon turf, and the right fiber depends on the use. For a residential yard, polyethylene is almost always the best balance of cost, appearance, and durability. For a putting green or a dog run that will get heavy use, nylon or a premium polyethylene may be worth the extra cost. If you see a very cheap roll being offered, it is almost certainly polypropylene, and it will not hold up to Seattle's wet climate or regular use.
Face Weight, Pile Height, Thatch and Backing: Reading a Turf Spec
A turf specification sheet tells you what you are buying. The most important numbers are face weight, pile height, infill type and rate, and backing type. Face weight is measured in ounces per square yard and tells you how much fiber is in the turf. A higher face weight means the turf is denser and will usually last longer and hide wear better. However, higher is not automatically better: a 50-ounce polyethylene turf for a residential yard is dense enough, while a 70-ounce turf for a dog run will be more durable. Pile height is the length of the visible blade, measured in inches. Short piles (under 1.25 inches) are used for putting greens and pet turf because they drain well and are easy to clean. Longer piles (1.5 to 2 inches) look lusher and feel softer but hold water and debris longer. The thatch layer is the curly, textured under-layer that props the blades up and hides the backing. A good thatch layer makes the turf look more natural and helps it recover from foot traffic.
Backing is the bottom layer that holds the fibers together. Latex backing is common and affordable; polyurethane backing is more durable and water-resistant. Some backings are fully permeable (water drains straight through), while others are perforated (water drains through small holes). Permeability is often stated in gallons per hour per square foot (GPH/SF). A fully permeable backing will drain 15 to 20 GPH/SF or more, which is important for pet turf and areas with heavy water use. When you ask for a quote, ask for these numbers in writing: turf product name, fiber type, face weight, pile height, thatch type, backing type, infill type and pounds per square foot, and base depth and material. Do not compare quotes on price alone. Compare them on the same specification, and ask any installer to put their spec in writing before you decide.
The Best Artificial Grass for Dogs, Kids, Putting and Pools
The best artificial grass for your yard depends on what it will be used for. For pet turf and dog runs, choose a short, dense pile (under 1.25 inches) with a fully permeable or well-perforated backing so urine drains quickly and does not pool. Antimicrobial infill such as zeolite or a coated infill like Envirofill will reduce odor and bacterial growth. For playgrounds and school turf, the turf must be soft and the base must include padding rated to the fall height of the equipment. Look for turf with a longer pile and a backing that provides impact attenuation. For putting greens, use dedicated putting turf, which is shorter and denser than landscape turf, installed over a shaped base that allows for proper ball roll and drainage. For pool surrounds, choose turf that is heat-rated and drains well, with a backing that does not trap water. Lighter colors and cooling infills help manage temperature in full sun.
Materials like SYNLawn, TigerTurf, AstroTurf, and Envirofill are examples of products that exist and can be sourced. No single brand is 'the best'; the right choice depends on your use, your budget, and the specific properties you need. A turf that is perfect for a dog run may not be ideal for a putting green, and a turf that looks great in a showroom may not perform well in Seattle's wet climate. The installer should help you choose based on your yard, your use, and what the turf will actually be exposed to.
How to Choose, and What to Get in Writing
When you are ready to get quotes, use this checklist to make sure you are comparing apples to apples. Ask each installer for the turf product name, fiber type (polyethylene, nylon, or polypropylene), face weight in ounces per square yard, and pile height in inches. Ask what infill they will use and how many pounds per square foot they will install. Ask how deep the base will be, what material it will be made of (crushed stone, recycled asphalt, or engineered base), and how it will be compacted. Ask whether a weed barrier will be installed and how seams will be joined and sealed. Ask for a certificate of insurance naming general liability and workers' compensation. Then compare the quotes on the same specification, not on price alone. A very cheap quote on a thin base or low-quality infill is not a bargain; it is a sign of corner-cutting that will show up within a year or two.
