When artificial turf smells like urine, the cause sits under the blades. Artificial turf smells when the infill soaks up urine and grows bacteria, and the smell is worst where the base drains poorly and urine sits. That makes the first step a cleaning routine and the second step a look at drainage. Ask us to check the drainage under your turf if the smell comes back after cleaning.
Drainage work under artificial turf runs $100 to $2,000 nationally, depending on the system, according to Bob Vila's 2023 artificial grass guide. Your Tampa price comes from a written quote after the crew comes out and measures. Ask for a written start date and finish date with the quote.
Why artificial grass smells like dog urine
The infill holds the smell
The cause comes down to two things working together: infill that soaks up urine, and bacteria that grow in it. Do you know which infill is in your turf? This Old House lists common turf infills as acrylic-coated sand, crumb rubber, silica sand and zeolite, applied to the maker's spec. Ask the installer which one went in, and keep that answer with your quote.
Whether you call it an artificial grass dog urine smell or a fake grass odor, bring the infill name to any quote and ask what the plan is for the infill and for where the urine goes next.
A base that drains poorly keeps urine in place
Urine sits where the base drains poorly, and that is where the smell is worst. So the next question is what sits under your turf. The This Old House install guide describes the usual build: remove at least 3 to 4 inches of soil with the old grass, then lay a 3 to 4 inch base of crushed stone or decomposed granite. The base is compacted with a plate compactor in several passes in different directions, and the weed-barrier seams overlap by 4 to 6 inches.
Ask for the base depth, rock type and compaction method in writing on your turf quote. If you already have turf, ask the installer for the same three details about your base. Wet ground is its own subject; our guide to reading wet ground in a yard covers it.
Tampa soil and rain make drainage a real question
The USDA Natural Resources Conservation Service describes Myakka fine sand, Florida's state soil, as poorly or very poorly drained, with the water table less than 18 inches down for 1 to 4 months in most years. That is a statewide series description, not a survey of any Tampa lot. UF/IFAS adds that many Florida flatwoods soils have a weakly cemented organic hardpan, usually 12 to 40 inches down, and a water table that rises to within 5 to 20 inches of the surface. Those depths explain why base depth and drainage matter on a pet-turf job here.
The rain arrives in a block. NOAA's climate normals for Tampa International Airport show 49.48 inches a year, and 30.24 inches of that falls from June through September, about 61% of the year. The National Weather Service puts the Tampa Bay rainy season at May 25 to October 10. After a summer storm, look at the pet area. Any spot where water still sits is worth showing the crew.
Pet turf smell fix: what to clean and check first
A basic upkeep routine
The routine for a pet area is short:
- Pick up solid waste daily.
- Hose pet areas once a month.
- Do an enzyme-cleaner deep clean twice a year.
Treat this as a starting routine, not a guarantee. If you are paying someone to maintain the turf, ask whether these three steps are in the price.
If the smell comes back after cleaning
If the routine does not clear the smell, the base is the next place to look. Note where the smell is strongest and whether that spot stays wet. A damp corner can point at the base rather than the blades.
Tampa has about 94 days a year at 90°F or hotter. A UF/IFAS study of California yards, reported in UF/IFAS News, found artificial turf surfaces can reach 174°F on the hottest summer days, while living grass stays near 102°F. UF/IFAS also says homeowners may end up watering artificial turf to make it bearable in summer. If you do, does that water drain away? Put that question to the crew as well.
Before anyone cuts, digs or re-lays turf
Ask for both the turf maker's warranty and the installer's workmanship warranty in writing. Bob Vila reports that some turf manufacturers warrant their product only if a professional installs it. If the fix means digging, Florida law requires a call to Sunshine 811 at least 2 full business days before the dig, and the locate ticket is good for 30 calendar days.

What fixing turf odor costs in Tampa, and how to hire
Prices to expect
Ask the installer to price pet turf, drainage and infill as separate lines. These national ranges come from 2023 and 2026 cost guides:
| Item | National range |
|---|---|
| Drainage under artificial turf, depending on the system (Bob Vila, 2023) | $100 to $2,000 |
| Crushed rock and decomposed granite base (Bob Vila, 2023) | $0.30 to $0.70 per square foot |
| Removing grass and debris before turf goes in (Bob Vila, 2023) | about $325 on average, about $575 with recycling |
| Artificial grass material alone (This Old House, 2026) | $2 to $8 per square foot |
| Professional turf installation labor (This Old House, 2026) | $4 to $12 per square foot |
| Professionally installed artificial lawn (This Old House, 2026) | $15 to $19 per square foot |
| Artificial grass, materials and installation, whole project (Bob Vila, 2023) | $2,961 to $7,792, national average $5,358 |
| Yearly upkeep of artificial grass (2026 cost guide) | $250 to $350 a year |
Base rock, weed barrier and infill are extra to the material price. What moves the price: how many square feet of turf are involved, whether the drainage under it needs work, whether the old turf and soil have to come out, and the turf material you choose.
A repair is one job and a replacement is another, so ask the crew to price each as its own line. This Old House, quoting a landscape contractor, puts the life of an artificial lawn at 15 to 20 years. That is a general figure, not a Florida one.

Tampa Landscaping Pros pulls the City permit when the job needs one.
How to hire for a pet turf smell fix
The Better Business Bureau says a company that quotes without seeing the yard cannot know what it needs, so get a price after an on-site look.
When the written price arrives, check it against the Federal Trade Commission's list: a written estimate should list the work, the materials, the completion date and the price. Compare bids for the same work, and ask for an explanation if the estimates differ a lot. The FTC also advises that you do not pay the full amount up front and that you make no final payment until the work is done and you are satisfied. Paying by check or card is better than cash.
A few questions are worth asking any turf company about a smell:
- Which infill is in my turf, and what is the plan for it?
- What is under the turf, and how deep is the base?
- Is drainage priced as its own line?
- What do the turf maker's warranty and your workmanship warranty cover, and for how long?
Questions about artificial turf that smells
Why does my artificial turf smell like urine?
Artificial turf smells when the infill soaks up urine and grows bacteria. The smell is worst where the base drains poorly and urine sits.
How often should I clean pet turf?
The routine is to pick up solid waste daily, hose pet areas once a month and do an enzyme-cleaner deep clean twice a year. Check the base if that routine does not clear the smell.
Why does drainage matter for turf in Tampa?
Urine sits where a base drains poorly, and Florida's state soil, Myakka fine sand, is poorly or very poorly drained. That is a statewide description, not a survey of your lot, so ask the crew to check how your base drains.
How much does drainage work under turf cost?
Bob Vila's 2023 guide gives $100 to $2,000 for drainage under artificial turf, depending on the system, as a national range. Ask for a written price per line before any work starts.
When should I check the drainage under my turf in Tampa?
Check right after a summer storm. The National Weather Service puts the Tampa Bay rainy season at May 25 to October 10, and any spot in the pet area where water still sits is worth showing the crew.
How do I compare quotes for a turf smell fix?
Line the bids up for the same work and ask each company to explain any large gap. Separate lines for pet turf, drainage and infill make that easy.
