Questions to Ask a Putting Green Installer Before You Hire

Q: What aggregate material will you use for my base, and how deep?

Good answer: A specific material is named — Class II decomposed granite, crushed limestone, or similar — with a depth of 4–6 inches. The contractor explains any site-specific reasons for their depth choice (soil type, drainage conditions, slope).

Red flag: “We use a good compacted base” with no specification of material or depth. Or proposing less than 4 inches without a clear technical reason.

Q: How many compacted lifts will you install the base in?

Good answer: The base is compacted in multiple lifts (passes) of 2–3 inches each, with the plate compactor run after each layer. This ensures consistent density throughout rather than just at the surface.

Red flag: Confusion about what a “lift” means, or confirmation that all base material is placed and compacted at once — this produces inconsistent density and future settling.

Q: How will you handle drainage for this specific site?

Good answer: The contractor explains their drainage assessment of your specific site — soil type, natural slope, proximity to structures — and tells you whether natural drainage through the base is adequate or whether additional drain lines are warranted. They have an opinion based on your site, not a generic answer.

Red flag: “Synthetic turf drains naturally so you don’t need to worry about it.” Drainage is always a site-specific engineering question — any contractor who dismisses it hasn’t thought seriously about your project.

Q: What excavation depth are you specifying and why?

Good answer: Total excavation depth is base depth plus turf thickness plus any sub-base drainage layer — typically 7–10 inches from finished grade. The contractor explains this calculation clearly.

Red flag: The contractor doesn’t know total excavation depth off the top of their head. An experienced installer has done this math hundreds of times.

Q: Do you install a weed barrier, and what type?

Good answer: Yes, a commercial-grade woven geotextile landscape fabric is installed between the base and the turf. They can specify the weight/grade.

Red flag: “We don’t usually do that” or describing a consumer-grade fabric. Without a proper weed barrier, vegetation growth through the turf is a matter of when, not if.

Q: What specific turf product are you recommending — brand, product name, fiber material?

Good answer: A named brand and product. Something like “We use [Brand] [Product Name] — it’s a nylon putting green turf with a 3/8-inch pile height, specifically designed for residential putting surfaces.” They can hand you or email the manufacturer spec sheet.

Red flag: “Premium putting green turf” or “professional-grade nylon” with no brand or product name. This is how contractors leave themselves room to install cheaper material after you’ve agreed on a price. Get the product name in the contract.

Q: What pile height are you recommending, and what stimp speed should I expect?

Good answer: Pile height for residential putting greens typically runs 3/8″–1/2″. The contractor can give you a realistic stimp expectation — most quality residential synthetic greens play at 8–10 on the stimpmeter, with premium products reaching 10–12. They know what their product delivers.

Red flag: Promising “tour speed” or stimp readings above 12 for a standard residential installation — this isn’t realistic with most synthetic products and typical infill applications.

Q: What infill material will you use and why?

Good answer: Silica sand is standard for putting greens — it’s clean, doesn’t absorb odor or moisture, and provides consistent infill density. Some contractors use specialty angular sand or purpose-designed putting green infill products. They can explain the performance trade-offs.

Red flag: Recommending crumb rubber infill for a putting green — it’s used in athletic fields and produces inconsistent ball roll. Not appropriate for a putting surface.

Q: Does my project require seaming? If so, what method do you use?

Good answer: For any green wider than the turf roll (typically 12–15 feet), seaming is required. The contractor explains their seaming method — heat-bonded tape or adhesive systems — and can show you examples of finished seam work in their portfolio.

Red flag: Contractor hasn’t thought about whether seaming is needed for your green dimensions, or dismisses the question. Seaming is a critical skill and a major failure point for inexperienced installers.

Q: Will the turf require a break-in or settling period before I can putt normally?

Good answer: Yes, typically 1–2 weeks of light use allows fibers to settle into their final position and infill to distribute evenly. The contractor sets accurate expectations and explains what to expect during this period.

Red flag: “It’s ready to putt on immediately.” Technically you can putt on it, but a new installer who doesn’t mention the settling period hasn’t thought carefully about the handoff experience.

Q: How many backyard putting green installations have you completed — specifically putting greens, not general turf?

Good answer: A confident number, delivered without hesitation. For a contractor you’d trust with a $10,000+ project, you want someone who has completed dozens of putting greens — not just a handful. They can describe the range of project types they’ve done.

Red flag: Pivoting to total turf installations rather than putting greens specifically. Residential putting green installation is a specialty. A contractor who primarily installs pet turf and lawn areas doesn’t have the same skill set.

Q: Can I see photos of 3 recent putting green projects, and visit one in person?

Good answer: Photos are produced immediately, and a site visit is arranged without resistance. Good contractors are proud of their work and understand that seeing it in person builds confidence.

Red flag: Only stock photos or manufacturer images on their website, or past projects described but photos not produced. If they’ve installed quality greens, they have photos of them.

Q: Who specifically will be on-site doing the work — you, a crew you manage, or a subcontracted crew?

Good answer: The contractor is on-site for all critical phases — base installation, compaction, turf seaming, and final inspection — whether or not they have additional crew. They’re accountable and present, not managing the project by phone.

Red flag: The project is being handed off entirely to a subcontracted crew the contractor hasn’t worked with extensively. It’s fine to use subs for excavation — it’s not fine to hand off the entire installation to an unfamiliar crew with no oversight.

Q: Can you provide 2–3 references from completed putting green projects in the last 12 months?

Good answer: References are provided promptly. Call them — not just to confirm they’re happy, but to ask specifically about how the contractor handled problems and whether the green still performs well.

Red flag: References from 3+ years ago only, or a contractor who “doesn’t give out customer information.” Recent references from completed jobs are standard practice for any legitimate contractor.

Q: Can you break down your quote by line item — base, drainage, turf, infill, cups, labor?

Good answer: An itemized quote is provided or can be produced. Even if the contractor typically quotes all-in, they should be able to tell you roughly what each component costs. This lets you compare quotes accurately and identify where costs differ between bidders. The cost guide explains what each price tier actually includes so you can spot when something is suspiciously low.

Red flag: Resistance to itemization — “it’s all included in the price.” Legitimate contractors have nothing to hide in their breakdown. Resistance usually means they’re obscuring a thin base budget or inferior turf.

Q: What is your payment schedule, and what milestone triggers each payment?

Good answer: Milestone-based payments tied to project progress. A reasonable structure: 20–30% at contract signing, 40–50% when base work is complete and you’ve inspected it, the remainder within 5–7 days of your satisfied sign-off at completion.

Red flag: 50% or more upfront before any work begins. Or 100% payment at “material delivery.” Your leverage disappears once payment is made — keep the final payment tied to your satisfaction with the completed work.

Q: What if the final cost exceeds your quote? Under what circumstances would you request additional payment?

Good answer: The contractor explains legitimate change order scenarios — buried utilities, unexpected rock, drainage conditions not visible until excavation — and confirms that any cost increase requires a written change order approved by you before work continues.

Red flag: Vague answer, or contractor who suggests verbal approval of cost increases is acceptable. “I’ll let you know if anything comes up” is not a change order process.

Q: Are permits required for this project in my jurisdiction, and who is responsible for pulling them?

Good answer: The contractor is familiar with local permit requirements, explains whether your project triggers any permit obligations, and confirms they handle permit applications if required. Permit costs should be disclosed in the quote.

Red flag: “We don’t worry about permits” without any explanation of why your specific project doesn’t require them. Drainage work connecting to municipal systems, significant grading, or HOA review requirements may all create permit or approval obligations.

Q: What does your labor warranty cover, and for how long?

Good answer: A minimum of 3 years on workmanship, covering base settling, seam failure, drainage issues, cup installation problems, and turf lifting at edges. The contractor can describe the warranty in specific terms, not marketing language.

Red flag: “We stand behind our work” with no defined period. Or a warranty period under 2 years — if a contractor doesn’t believe their base system will last 3+ years, that tells you something.

Q: What specifically voids the warranty?

Good answer: Reasonable exclusions: damage from heavy vehicles driven on the green, unauthorized modifications, or improper chemical applications. These should be clearly listed in the written contract — not described verbally as whatever seems convenient later.

Red flag: Broad voiding language that could be applied to nearly any complaint (“improper use,” “failure to follow maintenance instructions” with no specifics). Ask for the warranty exclusions in writing before signing.

Q: What is the turf manufacturer’s warranty, and how do I register it?

Good answer: The contractor provides the manufacturer’s warranty document — typically 8–15 years depending on the product and brand — and explains the registration process. They confirm whether the warranty is transferable to a new homeowner if you sell.

Red flag: The contractor doesn’t know the manufacturer’s warranty terms, or can’t provide the warranty document. If they’re recommending a product, they should know its warranty.

Q: How do I initiate a warranty claim if something goes wrong?

Good answer: A defined process: notify the contractor in writing, receive a response acknowledgment within X days, and a cure timeline. The contractor has a contact method and escalation path if the primary contact is unavailable.

Red flag: “Just call us if there’s a problem.” Verbal assurance with no defined process means no accountability. Get the warranty claim process in writing.

Before excavation starts: “Can you show me the design sketch and confirm final dimensions?”

Confirm the layout matches what you agreed to before any ground is broken. Changes after excavation cost money.

After excavation, before base goes in: “Can I verify excavation depth at several points?”

Bring a tape measure. Check depth at the center, edges, and low points. Verify it matches the specification in the contract.

After base is complete: “Can I inspect the base before turf installation begins?”

Walk the base, check depth, observe any visible drainage features. This is your last opportunity to catch base issues before they’re covered by turf. Once turf goes down, the base is inaccessible.

At completion: “Can you show me where the seams are?”

The contractor should be able to walk you to each seam and challenge you to find it by sight and touch. If they deflect this question, that’s a sign the seam quality isn’t something they’re proud of.
