Septic Installation & Excavation in Thomasville, NC – Chris Mendenhall

A septic system is only as good as the ground it sits in. At Chris Mendenhall Excavation & Septic LLC, we handle both. With a 4.9-star rating built on precise site work and quality septic installations, we’ve earned our reputation by understanding that proper excavation, grading, and drainage correction prevent septic failures before they happen. We move dirt, we clear land, and we install systems that last—because we own the equipment and the expertise to do it right.

From our location on Midway School Road, we serve Thomasville, Midway, Wallburg, Welcome, and Arcadia with comprehensive site work and septic services that cover everything from initial land clearing to complete septic system installation to repair work when existing systems fail. Whether you’re building on a fresh lot in the growing Wallburg area, dealing with drainage problems that threaten your drainfield, or replacing a failed system on rural property in Arcadia, Chris Mendenhall delivers the heavy equipment capability and technical knowledge northern Davidson County depends on.

We’re not a company that subcontracts excavation or brings in outside help. We’re owner-operated, we run our own equipment, and we take pride in the finished grade. When you hire Chris Mendenhall Excavation & Septic, you’re hiring a team that understands how proper site preparation protects septic systems from day one—and how fixing drainage problems can extend the life of existing systems by decades.

Complete Site Work & Septic Solutions

Chris Mendenhall Excavation & Septic provides integrated land development and septic services throughout Davidson County. Here’s what comprehensive site expertise means for your property:

• Septic System Installation (New Construction & Replacements) – Installing a septic system in Davidson County’s red clay requires more than just digging holes. You need proper grading to manage water runoff, correct soil preparation for drainfield absorption, precise tank placement to ensure gravity flow, and engineered solutions for challenging terrain. We handle complete installations from soil testing through final inspection—excavating the site, installing tanks and distribution boxes, laying drainfield laterals, and grading the area to prevent surface water from overwhelming the system. For the growing Midway and Wallburg housing markets, we install systems sized correctly for household needs and built to last decades, not just pass inspection.
• Excavation & Grading (Drainage Correction) – Water runoff is the enemy of septic drainfields. When surface water flows across a drainfield, it saturates the soil, prevents proper percolation, and causes premature system failure. We correct drainage problems through strategic grading—reshaping terrain to direct water away from drainfields, creating berms or swales to manage runoff, and ensuring your property drains properly before problems develop. For existing systems showing signs of stress (soggy spots, slow drains, surface water), drainage correction often extends system life by 10-15 years. Good grading saves septic systems, and that’s what we do.
• Land Clearing & Lot Preparation – Before you can build, you need buildable land. We clear lots for new construction—removing trees, grubbing stumps, stripping topsoil, and preparing sites for foundations and septic installations. Our heavy equipment handles dense vegetation, rocky soil, and challenging terrain throughout northern Davidson County. We don’t just clear indiscriminately—we work strategically to preserve trees where possible, minimize erosion, and create usable grades that facilitate proper drainage. Clean, professional lot prep that sets projects up for success from day one.
• Septic System Repair & Component Replacement – When existing systems fail, it’s often not the tank—it’s crushed inlet pipes, deteriorating distribution boxes, collapsed laterals, or settled grading that allows water to pool over the drainfield. We excavate to access failed components, replace what needs replacing with quality materials, and restore proper grades to ensure the repaired system functions as designed. This is heavy work requiring precision—digging carefully to avoid damaging functioning components, installing replacements that will last, and restoring your yard to usable condition when we’re done.
• Drainfield Restoration & Expansion – If your drainfield is failing but the tank is functional, full replacement might not be necessary. We assess whether the existing drainfield can be restored through excavation and regrading, or whether adding additional laterals can distribute flow more effectively. For properties on small lots where space is limited, creative engineering and precise grading can often extend system capacity without complete replacement. These solutions require understanding both septic systems and site work—knowing when excavation and drainage correction can solve problems that look like they need new drainfields.
• Site Grading & Rough-In Work – Beyond septic, we handle general site grading for driveways, home sites, outbuildings, and property improvements. We create level building pads, grade for proper drainage, prepare access roads, and perform the rough grading that makes properties functional. When you need heavy equipment moved precisely and finished grades that actually drain correctly, Chris Mendenhall brings the capability and attention to detail that separates professional site work from companies that just push dirt around.
• Emergency Excavation & Repair – When septic systems fail catastrophically—collapsed tanks, crushed mainlines, drainfield collapses—emergency excavation is necessary. We respond to urgent situations with the equipment and expertise to expose the problem, assess damage, and implement repairs quickly. Time matters when sewage is backing up or surfacing in your yard, and we have the capability to mobilize heavy equipment and solve problems that smaller contractors can’t handle.

Serving Midway, Wallburg, and Welcome

Located on Midway School Road, we are the go-to contractor for northern Davidson County—serving the rural landowners in Arcadia and Welcome, the established communities of Thomasville and Midway, and the rapidly growing Wallburg area where new subdivisions require professional septic installations and site preparation.

Wallburg’s growth creates steady demand for septic installations. New construction on previously undeveloped land requires proper site evaluation, soil testing, engineered systems, and precise installation. We work with builders and homeowners to install systems that meet Davidson County regulations while being sized appropriately for long-term use. Our reputation in the Wallburg market is built on systems that pass inspection the first time and function properly for decades.

Midway and Thomasville have a mix of older properties needing repairs and newer developments requiring installations. Older systems in these areas often fail because of poor original grading—water runs across drainfields during storms, saturating soil and preventing proper treatment. We correct these drainage problems, extending system life and avoiding expensive replacements. For new construction, we install systems with proper grading from day one, preventing the drainage issues that plague older installations.

Welcome and Arcadia represent rural Davidson County, where properties might have challenging terrain, rocky soil, or limited space for conventional drainfields. These properties require creative engineering—working with elevation changes, designing systems around existing features, and grading carefully to manage water in areas where natural drainage is poor. We’ve installed systems on properties other contractors said couldn’t support septic, using proper excavation and grading to create functional solutions.

Davidson County’s red clay creates specific challenges. It drains slowly (60-120 minutes per inch), which means drainfields must be properly sized and graded to handle effluent without becoming saturated. Clay’s tendency to compact makes excavation technique important—proper soil preparation in the drainfield area determines whether the system functions for 20 years or fails in 5. We understand this soil, and we excavate and grade accordingly.

Why Locals Trust Chris Mendenhall (4.9 Stars)

We Own the Equipment and the ExpertiseWe’re not coordinating subcontractors or renting equipment for each job. We own excavators, bulldozers, backhoes, and the full range of heavy equipment needed for professional site work and septic installation. That means we’re accountable for the work, we control quality at every step, and we don’t have scheduling delays waiting for rental availability or subcontractor coordination. When you hire Chris Mendenhall, you’re hiring a self-sufficient operation with the capability to handle complex projects from start to finish.

Owner-Operated Business, Owner-Level StandardsThis isn’t a large company where you never see the owner. Chris Mendenhall is on-site, running equipment, overseeing work, and ensuring every grade is finished correctly. That personal involvement means quality control happens in real-time, problems get solved immediately, and nothing leaves our hands until it meets the standards we’d expect on our own property. Owner-operated means accountability—our name is on the work, and our reputation depends on doing it right.

We Take Pride in the Finished GradeSite work isn’t just about moving dirt—it’s about creating functional grades that drain properly, look professional, and solve problems permanently. We don’t leave rough grades or drainage issues for homeowners to fix later. We finish the job completely, restoring yards to usable condition, ensuring water flows away from structures and drainfields, and creating finished surfaces that you can maintain with standard equipment. Professional finish work separates us from contractors who excavate and move on without fixing what they disturbed.

Good Drainage Saves Septic SystemsThe single biggest cause of premature septic failure is water—surface water overwhelming drainfields, runoff saturating soil, poor grading directing water toward systems instead of away. We prevent these problems through proper excavation and grading during installation, and we correct them through drainage work when repairing existing systems. This integrated understanding of site work and septic systems is what makes our installations last and our repairs actually solve problems instead of just replacing failed components.

We Handle the Work Other Contractors Can’tChallenging terrain? Rocky soil? Limited space? Drainage problems nobody else can solve? We take on difficult projects that require heavy equipment expertise and creative engineering. Northern Davidson County has properties where septic installation seems impossible—steep grades, poor soil, small lots. We’ve figured out solutions that work, using proper excavation, strategic grading, and technical knowledge that comes from years of doing this work.

4.9-Star Rating Reflects Consistent QualityYou don’t maintain a near-perfect rating without delivering quality work consistently. Every installation we complete, every repair we perform, and every drainage problem we solve is done with the same attention to precision and finished standards. Those reviews represent property owners across Davidson County who’ve seen the difference professional site work makes—installations that pass inspection easily, repairs that actually fix problems, and grading that prevents future failures.
