Home › Blog › Artificial Turf vs. Real Grass in the PNW: 10-Year Cost, Drainage, and Mud Season
Every Western Washington lawn has two seasons. There is mud season, which runs from about October to April, and there is brown season, which is the rest of the year unless you water.
That is the honest backdrop for the turf question. Not “is fake grass as nice as real grass,” but “what does each one actually cost me over ten years, and which one still looks like a lawn in February.” Here is how artificial grass installation compares to a natural lawn in the Pacific Northwest, with real numbers.
The 10-year cost, side by side
Natural lawn. A serviced lawn in Washington costs roughly $2,000 to $4,000 a year once you add it up: water through the dry months, mowing every week from March to October, fertilizer, moss and weed control, and the reseeding and thatching that mud season demands every spring. Over ten years that is $20,000 to $40,000, and at the end of it you have the same lawn you started with, still needing all of it.
If you mow it yourself, the cash cost drops. The Saturdays do not.
Artificial turf. An average turf project in Washington runs $8,000 to $28,000 installed. After that, upkeep is a rinse and an occasional power-brooming, call it $100 to $300 a year. Over ten years, turf costs the install plus a few thousand at most. Quality turf on a proper base lasts 15 to 20 years, so the ten-year math is only part of its life.
For most yards the two lines cross somewhere between year four and year eight. Everything after that is savings, plus a lawn that looks the same in February as it does in July.
Drainage: where the PNW decides the argument
Eight months of rain is the real test, and both options either pass or fail on drainage.
A natural lawn on the heavy, clay-rich soils common around Puget Sound holds water. The grass stops growing in the cold, the ground stays saturated, and foot traffic turns it to mud. Come spring, the low spots are bare and the moss has moved in. You reseed, it works until October, and the cycle repeats.
Artificial turf handles rain differently, but only if it is installed right. Quality turf has a perforated backing that drains water straight through. Under it sits a compacted aggregate base, graded so that water moves somewhere deliberate instead of pooling. Done properly, turf sheds a Washington downpour and is dry enough to walk on within the hour.
Done badly, it is worse than grass. Turf laid over poorly draining ground with a thin base turns into a waterbed in December, and the seams lift. That is the shortcut install, and it is why the base matters more than the turf you pick. We covered the full process in our post on artificial turf installation in the PNW.
Mud season, dogs, and the shady yard
Three situations where turf wins by a wide margin.
The mud-season yard. If your lawn is unusable from October to April, you are paying for a lawn you get to use half the year. Turf gives you the other half back.
Dogs. A natural lawn with a dog is a lawn with dead spots, dug holes, and a mud path along the fence. A pet turf area with the right infill and drainage handles all of it, rinses clean, and does not track mud into the house.
Shade. Grass under big Northwest evergreens does not grow. It thins, mosses over, and turns to dirt no matter how many times you reseed. Turf does not care about sun.
When real grass still wins
We will tell you straight when turf is the wrong call, because it sometimes is.
If you love the ritual of a real lawn, the smell of it cut, the way it feels barefoot in July, that is a real reason and turf will not replace it. If the space doubles as a garden or a play area where you want living soil, grass wins. If your yard drains well, gets good sun, and you are already happy with what it costs to keep, there is no problem to solve.
And on very large lots, the turf install cost can outrun the savings for a long time. Turf makes the most sense on the yard you actually use: the back lawn, the dog run, the side yard that never dries out.
