Repair or replace artificial turf: the signs that decide it

01Is it worn out, or does it just need work?

Start with what you see:

FusionTurf, a turf maker, draws the same line: matted turf with sound fibers gets “a power broom and infill reset,” and replacement is worth considering “when backing cracks, seams consistently fail, or fiber wear is widespread and grooming no longer restores performance” (FusionTurf).

Don’t sit on a small repair. Synthetic Grass Warehouse (SGW), a turf distributor, says seam ruptures “get worse over time,” and the longer the wait, the more repairs to make (SGW).

02Which wear signs mean the turf itself is done?

Four, each with a quick check.

• Bare traffic paths. SGW says a backyard with daily play “will age faster in high-traffic paths” (SGW). Brush the path hard against the grain. Blades that rise were matted; short, thin blades with backing showing between tufts are gone. Low infill speeds this up: The Motz Group, a sports-field builder, says “Reduction of infill levels causes turf fibers to degrade faster” (Motz), and a 2020 NTNU review notes that fiber left bare by low infill takes more UV.
• Brittle, faded tips. Bend a few blades over. Tips that snap or crumble have lost their strength. The same review calls UV radiation, with surface heating, the most damaging cause of fiber degradation, and the Colorado Climate Center notes that the state’s thin atmosphere “allows greater penetration of solar radiation” (Colorado Climate Center). Cold adds breakage: below freezing, the review says, fibers turn stiffer and more brittle, and the nearest NOAA station, Fort Collins, averages 150 days a year with a low at or below 32°F (NOAA). More in does artificial turf fade.
• Backing failure. Fold back an edge and pull a few tufts. Cracked backing, or tufts that come free with an easy pinch, mean the coating that locks fibers in has let go. The Synthetic Turf Council defines tuft bind as the force “required to pull a tuft from the synthetic grass backing” and recommends 6.8 pounds (STC).
• A smell that keeps coming back. Where a dog uses the same stretch every day, Motz says, urine “can build up in the turf’s individual layers” (Motz). Work through the fixes in dog urine smell in artificial turf first. If it returns after the old infill is out and the turf deep-cleaned, it lives in the backing and base.

Two local codes use the same words. Firestone’s code lists “heat degradation, depressions, odors, excessive wear” among the deterioration turf may not show, and requires turf to be “replaced after the life expectancy has been reached” (Firestone Development Code 16.6.4). Platteville’s nuisance code names turf “that is falling apart or is not uniform in color” (Platteville Sec. 7-1-30). Not legal advice.

Hail belongs on the list too: NOAA logged 536 hail reports in Weld County and 253 in Larimer from 2011 through 2025 (NOAA Storm Events). See does hail damage artificial turf.

03When does repairing stop making sense?

When the patch will never match, or the damage is everywhere.

• Old turf won’t match new. SGW says matching turf from an earlier install “can also be tricky, even if it’s the same product; environmental exposure and wear can change the appearance over time” (SGW). Shaw’s installation guidelines add that turf is made in batches “with normal batch to batch variation” (Shaw). A bright patch in a sun-bleached yard stays bright, and in Firestone that is a code matter: worn areas are to be “repaired or removed and replaced in manner that results in consistent appearance with the existing artificial turf.”
• The damage is spread out. Every fix lands next to more worn turf.
• It’s a putting green that has shrunk. SGW’s column says that when a green moves “causing shrinkage and/or seam rupture, there is only one option, and that is to be removed and replaced.” Backyard greens are on our putting greens page.

Young turf that is failing may point to the install, not wear: see checking a turf install and when an installer won’t come back.

04Can new turf go over the old turf?

No. The old turf comes out, infill and all. SYNLawn’s DIY guidelines begin by removing “the grass, dirt, rock, or whatever is in the area” the new turf will cover (SYNLawn), and old turf is part of whatever. Left in place, it:

• puts a second backing, with whatever infill is trapped in it, between the new turf and the base, and the drainage holes in two backings won’t line up;
• keeps its smell. Motz makes the point about infill: “adding an odor-fighting infill on top of your old, smelly infill won’t fix matters”;
• carries every dip and ridge up into the new surface. The Synthetic Turf Council says irregularities in a base “are typically reflected in the finished field surface” (STC).

In Firestone, turf “shall be installed over a compacted and porous aggregate base material that is a minimum of three (3) inches deep,” and old turf is not that. Not legal advice. Hauling it away is in how to dispose of artificial turf.

05Can the old base be reused?

Often, if it still does its job. On sports fields, Motz says “the base and drainage systems can be reused” when the turf is replaced (Motz). Once the old turf and infill are off, check a backyard base for five things:

• Firm. FusionTurf’s test for a finished base: no footprints or rutting under normal walking (FusionTurf).
• Flat. It calls about 1/2 inch over 10 feet acceptable for landscapes. Dips from clay moving underneath get fixed now, not under new turf; see sinking and low spots.
• Draining. Water from a hose should soak in, not stand.
• Clean. FusionTurf digs out “loose or contaminated base” down to firm support. Base under a dog area that smelled through a deep clean counts as contaminated.
• Deep enough. In Firestone, still the 3-inch minimum above.

What goes under turf, and how deep, is in what base goes under artificial turf.

06What changes when replacement turf goes in after 2026?

The state’s PFAS rule: from January 1, 2026, C.R.S. 25-15-605 says a person “SHALL NOT INSTALL ARTIFICIAL TURF THAT CONTAINS INTENTIONALLY ADDED PFAS CHEMICALS” anywhere in Colorado, while nothing in it stops anyone “MAINTAINING ARTIFICIAL TURF INSTALLED BEFORE JANUARY 1, 2026” (SB24-081, signed act; bill summary). A replacement is new turf going in, so read it as covered. Whether a patch counts as installing or maintaining isn’t settled, so ask for the maker’s PFAS documentation for any new piece. Not legal advice.

Back in Northern Colorado:

• Firestone requires a town permit before anyone installs artificial turf, with no fee for single-family homes. Does a like-for-like replacement need one? It depends; ask Firestone Planning before the old turf comes up.
• HOA common areas. State law bars nonfunctional artificial turf from new development and redevelopment on HOA common property but lets local governments allow pre-2026 turf to be maintained (SB24-005); Wellington’s code says so in its own words. Whether replacing counts as maintaining is untested; see artificial turf rules in Northern Colorado.
• Your own HOA. If it approved the original turf, ask whether a replacement needs a new request. HOA turf approval lists what goes in one.

07What goes into the cost of replacing turf?

What a replacement quote should spell out:

1. Taking out the old turf and infill. Sand infill is heavy: Shaw estimates three to five pounds per square foot on typical landscape turf, roughly 1,500 to 2,500 pounds in a 500-square-foot yard.
2. The base. Reused as it is, regraded and re-compacted, topped up, or dug out where it is soft or soaked.
3. The new turf and infill, with a spec sheet and PFAS paperwork; see what a turf spec sheet should say.
4. Edges, seams, access and hauling, as in what drives artificial turf cost.
5. Permits and HOA steps, where they apply.

Ask any installer what they would reuse and why. A good answer names the base checks above and where the old turf goes. A full install is on our artificial turf installation page.
