Septic System Inspections
A professional septic inspection gives you a clear picture of your system's condition — whether you are buying a home, selling a property, or simply want to know how your system is performing. Thomasson Septic & Excavating provides thorough inspections with detailed reports and photos, suitable for real estate transactions, lender requirements, and peace of mind.
What Our Inspection Includes
Our septic inspection is a comprehensive evaluation of your system's visible and accessible components. We assess the system from the cleanout at the house through the distribution box and drain field area.
- ✓Visual inspection of the septic tank, including lid condition, inlet and outlet pipes, and baffle condition
- ✓Assessment of the distribution box for level, structural integrity, and proper flow distribution
- ✓Evaluation of the drain field area for signs of failure (wet spots, odors, surfacing effluent, unusually green grass)
- ✓Check of the cleanout and pipe connections from the house to the tank
- ✓Detailed written report with photos documenting system condition and any issues found
- ✓Recommendations for any repairs, maintenance, or follow-up actions needed
Conventional vs. Alternative System Inspections
Conventional and alternative septic systems require different inspection approaches. Conventional systems have relatively simple gravity-fed components (tank, D-box, drain field) that are assessed visually and through flow testing. Alternative systems — mound systems, sand filter systems, aerobic treatment units — have additional mechanical and engineered components that require specialized knowledge to evaluate properly.
Our inspectors are experienced with both conventional and alternative systems across all six counties in our service area. We know what to look for in each system type and can identify issues that a less experienced inspector might miss.
When You Need an Inspection
There are several situations where a professional septic inspection is essential or highly recommended.
- ✓Home Sale — Most lenders require a satisfactory septic inspection before financing a purchase. Sellers benefit from pre-listing inspections to avoid surprises during the transaction.
- ✓Home Purchase — Protect your investment by knowing the true condition of the septic system before you buy. This is especially important for older homes in areas like Lake of the Woods, Catlett, and Remington.
- ✓Routine Maintenance — Regular inspections every 3 to 5 years catch developing problems before they become costly emergencies.
- ✓Warning Signs — If you notice slow drains, odors, wet spots, or other symptoms, an inspection determines the cause and severity.
Virginia Inspection Requirements for Real Estate
Virginia requires sellers to disclose known septic system issues during real estate transactions. While a formal pre-sale inspection is not mandated by state law in all cases, most mortgage lenders require a satisfactory inspection report before approving financing. In practice, septic inspections are a standard part of the home buying process throughout Central Virginia — particularly in communities like Lake of the Woods where aging systems are common.
Our inspection reports are detailed enough for lender requirements and include photos, condition assessments, and clear recommendations. If an inspection reveals issues, we can provide repair estimates so buyers and sellers can negotiate from a position of knowledge.
What Happens If We Find Problems
If our inspection reveals issues with your septic system, we provide a clear explanation of the problem, its severity, and your options. Minor issues may need simple repairs — a shifted distribution box, a damaged baffle, or a minor pipe crack. More significant issues like drain field failure or a structurally compromised tank may require component replacement or a full system replacement.
As both inspectors and installers, we can handle everything from diagnosis through repair — you do not need to hire a separate contractor to fix what we find. We also provide honest assessments: if a system is functioning properly, we will tell you so, even if it means less work for us.

Frequently Asked Questions
What does a septic inspection include?
Our inspection covers the tank (lid, baffles, inlet/outlet), distribution box (level, condition, flow), drain field area (signs of failure), and connections from the house. You receive a detailed written report with photos and recommendations.
How long does a septic inspection take?
A typical septic inspection takes 1 to 2 hours on-site, depending on system accessibility and complexity. Alternative systems may take longer due to additional components. We schedule inspections at your convenience and provide the written report promptly after the inspection.
How much does a septic inspection cost?
Contact us for current inspection pricing. Our inspections include a thorough on-site evaluation, photos, and a detailed written report suitable for real estate transactions and lender requirements.
Do I need a septic inspection to sell my home?
While Virginia does not mandate a pre-sale septic inspection in all cases, most mortgage lenders require one before financing. A pre-listing inspection also helps sellers identify and address issues before they become deal-breakers during negotiations.
How often should I have my septic system inspected?
We recommend inspections every 3 to 5 years for conventional systems. Older systems (20+ years), alternative systems with mechanical components, and systems near waterways should be inspected more frequently. Regular inspections catch problems early when repairs are simpler and less expensive.
What is the difference between a conventional and alternative system inspection?
Conventional system inspections focus on the tank, distribution box, and gravity-fed drain field. Alternative system inspections include these same components plus evaluation of mechanical parts (pumps, aerators, dosing systems), engineered treatment components (sand filters, mound fill material), and any alarms or control panels.
Can you inspect a system before I buy a property?
Yes — pre-purchase inspections are one of our most common services. We inspect the system, document its condition with photos, and provide a clear report that you can share with your lender and use in purchase negotiations. For older homes in Lake of the Woods, Catlett, Remington, and other communities with aging systems, a pre-purchase inspection is essential.
