Great company. Very professional. Great prices. Cleaned up after doing work. Answered questions. Difference of night and day from old unit to new.
Overgrown beds and patchy lawns don't fix themselves. Weeds spread fast in our warm, humid climate. Grass gets thin and brown without the right feeding schedule. Regular care keeps your yard healthy all year. A little attention each season saves you bigger fixes later on.

Our humid summers hit St. Augustine lawns hard with brown patch and gray leaf spot, especially around Carolina Forest and Conway. If your grass looks blotchy or thin after a hot stretch, it's time to call. Sandy soil here drains fast and loses nutrients quickly. Skipped feedings show up fast as bare or yellow patches. Landscape maintenance [1] done on a steady schedule catches these problems before they spread. Hurricane season dumps heavy rain in this area. Low spots near the Waccamaw River can flood. This leaves fungus and standing water behind. Waiting until the yard looks bad usually means a bigger bill later.
Humid summers spread fungus fast on St. Augustine lawns. We treat it before it spreads across your yard.
Hedges left too long block light and attract pests. Bugs and mold like to hide in thick, overgrown branches. Your other plants suffer when hedges hog the sunlight. Regular trims keep them tidy and healthy. A good shape now means less work for you down the road.
Sandy soil loses nutrients fast. We fertilize on a schedule that fits our local growing season.
Mole crickets and chinch bugs are common here. We spot the damage early and treat it right.
Heavy rain from hurricane season leaves standing water and debris. We clean up and restore your lawn.
Winter turns lawns brown here. We overseed with ryegrass to keep yards green through the cold months.
A lawn problem left alone gets worse fast in our climate. Fungus spreads, pests multiply, and dead patches grow wider. We show up quickly and treat the real cause, not just the surface. That's what keeps your yard looking good all year.
Don't let brown patches or overgrown beds get worse. Our Services team at Keystone Maintenance can get your yard back on track this week.
We keep the process simple so you know what to expect from start to finish. First, we look at your yard and talk about your goals. Then we give you a clear price with no surprises. Our crew shows up on time and gets right to work. You get updates along the way, not just a bill at the end.
Reach out by phone or book online in minutes. We'll ask about your yard and any problem spots.
We walk your property and check soil, grass type, and any pest or fungus issues. Then we build a plan that fits your yard.
We handle mowing, feeding, trimming, and treatment on a schedule. You get a lawn that stays healthy through every season.
Price depends on lot size, grass type, and how much work your yard needs. A small Surfside Beach yard costs less than a half-acre lot in Conway with mixed pine canopy. We give you a free estimate before we start, so there are no surprises. Sandy soil here often needs more frequent feeding, which we'll factor into your plan.
Great company. Very professional. Great prices. Cleaned up after doing work. Answered questions. Difference of night and day from old unit to new.

Here are answers to what Horry County homeowners ask us most. We hear the same questions from folks in Myrtle Beach and Conway. Weather, soil, and local pests shape a lot of these answers. We wrote them down so you don't have to call and ask.
Most Horry County yards run $100 to $600 a month depending on size and needs. We give you a free estimate first. Bigger lots in Conway or Aynor cost more than small HOA lawns in Market Common.
Most visits take 30 minutes to 2 hours. It depends on lot size and what services you need. A full treatment with trimming and feeding takes longer than a basic mow.
DIY works for small, simple lawns with no pest or fungus issues. But our sandy soil and humid summers cause problems that are hard to catch early. We know what to look for and treat it before it spreads.
Most lawns need weekly care from April through September. In winter, service drops to monthly cleanup and dormant feeding. We'll set a schedule that fits your yard and budget.
We offer fast 24 hour service for urgent issues like storm damage or spreading fungus. Just call and we'll get someone out quickly. Waiting too long lets small problems get bigger fast.
Look for brown or yellow patches, thinning grass, or standing water after rain. Overgrown hedges and weeds taking over beds are also signs. These get worse fast in our climate if ignored.
Yes, we work with HOA rules in communities like Grande Dunes and Market Common. We know the detail level these neighborhoods expect. Just let us know your HOA's requirements and we'll match them.
