Your home’s most expensive repairs happen when the lawn crew doesn’t know where the septic lines run, or when the landscaper plants water-hungry shrubs over your drainfield. Thames Lawn Care, Pressure Washing, & Septic Service has built its 4.8-star reputation (226 reviews) by being the only Sumter company that understands how everything on your property works together—from the grass to the tank. Operating from our Twin Lakes Drive headquarters, we’re the total property care solution for military families at Shaw Air Force Base, rural estates in Wedgefield, and lakeside homes in Manning who need professionals that protect their investment above ground and below.
We’re not three separate contractors you have to coordinate and hope don’t mess up each other’s work. From the sandhills soil in Dalzell that requires careful drainfield management to the humidity-driven mildew that attacks Sumter’s siding every summer, this region demands property maintenance that considers the whole system. Whether you’re a Shaw AFB family on PCS orders needing the yard picture-perfect for sale, or a longtime Sumter resident managing a rural property near Swan Lake Iris Gardens, Thames handles what’s under the ground and what’s above it with the same Gamecock City work ethic.
Sumter’s All-in-One Property Maintenance
Thames combines septic expertise, professional landscaping, and pressure washing services to provide comprehensive property care that protects your home’s infrastructure while maintaining curb appeal. Our cross-trained crews understand how each service affects the others—a level of integration that separate contractors simply cannot match.
- Septic Tank Pumping & System Maintenance — Wedgefield, Dalzell, and rural Sumter County properties rely on septic systems that need pumping every 3-5 years depending on household size. We remove sludge and scum layers completely (not the “quick pump” that leaves half the solids behind), inspect baffles and filters, and provide honest assessments of system health. Our septic technicians coordinate with our landscaping crews to mark drainfield locations permanently, preventing future damage from heavy equipment or inappropriate plantings. Common in older properties around Poinsett State Park and Manning’s lakeside estates.
- Professional Landscaping with Septic Awareness — Most landscapers will plant whatever looks good without considering what’s buried beneath. Thames designs and maintains yards that enhance your property while protecting septic infrastructure. We avoid deep-rooted trees near lateral lines, select grass species appropriate for drainfield areas (no water-hogging plants that compete with soil absorption), and plan irrigation systems that don’t overload your septic capacity. From routine mowing and edging to seasonal plantings and mulch installation, we maintain your outdoor spaces with knowledge of what’s underground. Essential for Shaw AFB families who need base-housing-quality maintenance without septic failures.
- Root Mitigation & Drainfield Protection — Sumter’s mature oaks and pines are beautiful until their roots invade your septic laterals. Our dual expertise in landscaping and septic service allows us to identify trees threatening your system, install root barriers where needed, and recommend strategic removals before roots cause $15,000+ drainfield replacements. We also educate homeowners on drainfield protection—no parking RVs or heavy equipment over lateral lines, no building sheds or pools near the absorption area, and proper surface water management to prevent hydraulic overload.
- Pressure Washing for Curb Appeal & Maintenance — Sumter’s humid climate creates perfect conditions for mildew, algae, and dirt buildup on siding, driveways, and decks. We provide professional soft-wash and high-pressure cleaning services that restore curb appeal without damaging surfaces. Critical for Shaw AFB military families preparing homes for sale during PCS season—buyers expect clean exteriors and driveways. We also pressure wash concrete pads, fences, and pool decks, removing years of buildup that shortens material lifespan. Our cleaning technicians avoid spraying near septic tank lids and drainfield areas to prevent soil compaction.
- Hardscaping & Drainage Management — Poor surface water drainage can overload your septic system and cause yard flooding. Thames installs retaining walls, French drains, and grading solutions that direct water away from drainfields and foundations. Our hardscaping services include paver patios, walkways, and decorative rock installations—all planned with septic system locations in mind. We’ll never install a heavy paver patio over your drainfield or create drainage that channels water into your absorption area. Common need in Dalzell’s rolling terrain and Manning’s lakeside properties with challenging topography.
- Seasonal Property Maintenance — From spring mulching and summer lawn care to fall leaf removal and winter storm cleanup, Thames provides year-round maintenance that keeps your property looking sharp while protecting septic infrastructure. We coordinate seasonal tasks to prevent compaction over drainfields during wet months, time tree trimming to avoid root disturbance near lateral lines, and maintain proper grading to prevent surface water infiltration into your septic system.

Why Sumter Trusts Thames
Total Property Care Philosophy — The Thames difference is simple: we handle what’s under the ground and what’s above it. When your septic technician is also your landscaper, there’s no miscommunication about drainfield locations, no accidental damage from mowers or aerators, and no planting disasters that compromise system function. One call maintains your yard and protects your home’s most expensive infrastructure. Our 226 reviews consistently praise our “knows what he’s doing,” “takes care of everything,” and “finally found someone who understands septic AND landscaping” versatility.
Cross-Trained Crews with Gamecock City Work Ethic — Every Thames crew member receives training in both landscaping and septic awareness. Our mowing teams know where laterals run and avoid compacting drainfield soil. Our septic technicians understand landscaping enough to advise on proper plantings and drainage. This cross-training prevents the costly mistakes that happen when separate contractors work in isolation—like the tree service that damages septic lines while removing stumps, or the landscaper who plants willows directly over your absorption field.
Military Family Friendly — Shaw Air Force Base families face unique challenges: frequent relocations, deployment schedules, and base housing standards that require professional maintenance. Thames works with PCS timelines, provides service while family members are deployed, and ensures properties meet the curb appeal standards that help homes sell quickly during transfer season. We understand military schedules and the importance of reliable, efficient service.
Honest Assessments & Fair Pricing — We don’t upsell unnecessary services or hide septic problems to keep landscaping contracts. If your drainfield is failing, we’ll tell you honestly—even if it means delaying landscaping projects. If your pressure washing quote seems high, we’ll explain why (square footage, mildew severity, surface type) rather than giving a low-ball estimate and adding charges later. Transparency builds the trust that earned our 4.8-star reputation across 226 reviews.
4.8-Star Reputation (226 Reviews) — Sumter County homeowners have left 226 reviews praising our “all-in-one service,” “knows septic systems,” “yard looks great and no worries about the tank,” and “military-family reliable” approach. When you need property maintenance that protects your septic investment while keeping your home beautiful, Thames is the one call that handles it all.
