Sub Base Types — Family-owned, 4.9★ rated, 15-year warranty
A lot of Suwanee homeowners ask us about putting greens, and honestly, it makes sense. Whether you're in Suwanee Station near the Town Center Park or over in Shadowbrook, the idea of having a short-game practice area in your own backyard is pretty appealing. The thing is, a putting green isn't just about rolling out some carpet and calling it done. The sub-base—that's the foundation underneath—is what separates a green that plays beautifully for years from one that becomes a maintenance headache. We've installed plenty of these in Gwinnett County, and we've learned a lot about what works specifically in our area. Your soil matters. Your drainage situation matters. Even how much shade you get from those Georgia pines matters. We're going to walk you through what we recommend for Suwanee properties, what we typically see in yards around here, and honestly, what mistakes people make when they try to DIY this. If you're thinking about adding a putting green, let's talk about getting the sub-base right so you actually enjoy using it year-round.
Suwanee sits on Gwinnett clay, which is heavy and holds moisture longer than sandy soils. That's actually good news for putting green drainage if you prepare the sub-base correctly. A lot of homeowners here have quarter-acre to half-acre yards, which is plenty of room for a 200–400 square foot green. The tricky part is that clay doesn't drain on its own, so we layer in crushed stone and sometimes geotextile fabric to keep water moving away from the turf surface. Sun exposure varies a lot depending on whether you're surrounded by mature pines (common in Shadowbrook) or in a newer subdivision lot (more typical in Suwanee Station). North-facing greens in shaded areas need different turf selections than south-facing ones. HOA rules in Suwanee are usually reasonable about artificial turf—most communities see it as responsible land stewardship—but always check your covenant before we start. The Suwanee Creek Greenway runs through the area, which means some properties have better natural drainage toward creek corridors. We account for that during site prep. The clay soil is dense enough that we don't need as much compaction, but we do need proper grading to prevent ponding. That's where the sub-base design really earns its keep.
Yes. Gwinnett clay is dense and doesn't self-drain like sandy soil. We install a sub-base with crushed limestone or granite dust, usually 4–6 inches, plus a perforated drain layer if needed. Your site's slope and whether you're near the Greenway also matter. We'll assess your lot's natural grade during the site visit and design the sub-base to shed water properly so your green stays playable year-round.
Cost depends on size and sub-base complexity. A 300 sq ft green with proper Suwanee-specific sub-base prep (grading, stone, geotextile, turf) typically runs between $4,500–$7,500. Larger greens or properties with severe grading challenges run higher. We quote every job individually because soil and drainage aren't one-size-fits-all.
Absolutely. Shadowbrook and other Suwanee neighborhoods have established trees that block sun, especially in winter. We recommend turf varieties that handle partial shade well. Some homeowners add subtle ground contouring or thin out overhanging branches to boost light. During your consultation, we'll walk the yard at different times of day to plan accordingly.
Site prep, sub-base installation, and turf laying typically takes 3–5 days depending on your yard's size and soil conditions. Clay sub-base work takes longer than sandy soil because of grading and compaction precision. We'll give you a firm timeline after the initial walkthrough so you know exactly when to expect us.
