Selling a Warrenton home with a private well or septic system can feel like juggling unknowns. You want a smooth sale, fewer surprises, and confident buyers. The fastest way to get there is to prepare clear, current well water tests and septic documentation before you list. In this guide, you’ll get a step-by-step Fauquier-focused checklist, timelines, costs, and exactly which records to pull so buyers see credible documentation on day one. Let’s dive in.
Why prep well and septic now
When a property relies on a private well and an onsite sewage system, buyers and lenders often expect recent water test results and a septic evaluation during due diligence. If you provide these reports upfront, you reduce delays, keep negotiations cleaner, and help buyers feel secure about the home’s condition. You also support Virginia disclosure requirements by sharing known issues with water quality or the septic system.
Put simply, pre-listing prep shortens escrow, builds trust, and lowers the risk of price cuts tied to unknown condition items.
Well testing checklist
What to test
Start with the tests most buyers and lenders expect and expand as needed for your property:
- Bacteria screening: Total coliform and E. coli (presence/absence). Recommended annually and at sale.
- Nitrate as nitrogen. Add nitrite if nitrate is elevated. Many lenders look for this.
- Basic chemistry: pH, hardness, total dissolved solids, and conductivity.
- Common Virginia well concerns: iron, manganese, and sulfate. These are often aesthetic but buyers want to know.
- Metals as indicated: lead and copper, especially with older plumbing or brass/lead solder.
- Property-specific add-ons: sodium, arsenic, volatile organic compounds if near industrial uses or old tanks, and PFAS where regional results suggest risk.
- Radon: usually an indoor air test; radon in well water can be a consideration in parts of Virginia but is not a common default.
Aim to provide a clean, signed lab report for bacteria and nitrate at minimum. Many buyers will accept that as an initial pass.
Who should test
Use a state-certified drinking water laboratory and follow their sampling instructions closely. Certified labs and guidance are available through the Virginia Department of Health. Improper collection can invalidate results, especially for bacteria, so consider having a qualified provider collect samples for you.
Documents to gather for your listing packet
- Well log or drilling report with depth, casing, static level, and yield.
- Pump installation and service records, including dates and model.
- Water treatment system manuals and maintenance records for filters, softeners, UV units, or chlorinators.
- Previous lab reports from the last 1 to 3 years.
- Any permits related to the well or treatment system.
- Notes on any seasonal issues, odors, discoloration, or recent repairs.
Organize everything in a single digital folder and a thin binder for showings.
How to interpret results
- Bacteria: Any E. coli or fecal indicator usually calls for immediate remediation such as shock chlorination and re-testing, or repair if the source is structural.
- Nitrate: Levels above 10 mg/L as nitrogen are a health concern. Expect remediation requests or disclosures.
- Aesthetic issues such as iron, manganese, or hardness are common. If you have treatment in place, document the system and recent service.
Plan for a retest if anything flags. Clean follow-up results help keep your contract on track.
Timing and cost expectations
- Bacteria results: 24 to 72 hours from the lab.
- Chemistry and metals: several days to about a week.
- Start testing 2 to 3 weeks before listing to allow time for remediation and re-testing if needed.
- Typical costs: about 50 to 200 dollars for a basic bacteria plus nitrate panel; 100 to 400 dollars for extended chemistry or metals. Radon air testing, if you choose to add it, is often 100 to 200 dollars.
Septic system checklist
What buyers expect from a septic evaluation
Most buyers want recent proof that the system is functioning as intended. An evaluation typically looks for backups or slow drains, checks tank condition, measures scum and sludge depth if pumped, and assesses drainfield performance through observation and sometimes a dye or effluent flow test. A new soil percolation study is not needed for most resales.
Septic records to gather
- Original permit and as-built drawing with tank size, location, drainfield layout, and reserve area.
- Pumping receipts and service notes, including alarm testing if applicable.
- Any repair or alteration permits and contractor documentation.
- Installer or service provider contact information.
- Marked locations of tank lids, cleanouts, and key components.
These documents help inspectors, buyers, and appraisers verify the system without guesswork.
Pumping, inspection, and remediation steps
Recommended pre-listing actions:
- Schedule tank pumping and keep the receipt. Pumping helps your inspector see baffles and internal components.
- Book a septic inspection or evaluation with a licensed professional. If the county offers evaluation services, ask about availability.
- If the inspector identifies repairs, request written estimates and plan your path forward. Consider completing small fixes before listing. For larger items, disclose and price accordingly.
Costs and timelines
- Septic inspection or evaluation: often 250 to 600 dollars depending on scope.
- Tank pumping: often 200 to 500 dollars based on size and access.
- Repairs vary widely, from minor baffle work to full drainfield replacement. Get local quotes.
- Many inspections take a few hours on site, with a written report delivered shortly after.
Disclosure and buyer expectations
Buyers commonly ask for a recent inspection report or a pumping receipt within the last 6 to 12 months. If your system is marginal or has a history of issues, gather quotes early and decide whether to complete repairs or disclose and adjust pricing. Clear documentation helps keep negotiations focused and fair.
Local Fauquier steps and who to call
Where to get official records
- Fauquier County Environmental Health can provide septic permits, as-builts, and some system histories. Request copies for your listing packet.
- For well logs and construction details, check with the Virginia Department of Health or the original well driller. Some records may also be held locally.
- Keep notes of your requests and include copies of any records you obtain.
Lender and buyer requirements to anticipate
Buyers using conventional, FHA, or VA financing may need proof of safe, potable water and a functioning sewage system. Some lenders require a passing lab report for bacteria and nitrate for private wells. Confirm specific requirements early with the buyer’s agent or lender so your documentation aligns with underwriting.
Legal and disclosure reminders
Virginia sellers must disclose known material defects. If you know about water quality problems or septic issues, document them and provide certified lab reports and inspection records. For exact disclosure language, consult your real estate agent or attorney.

Practical tips to keep the process smooth
- Start early. Labs and septic schedules fill fast in spring and summer.
- Follow sampling instructions exactly to avoid invalid tests and retakes.
- Flag any known issues upfront. Buyers respond better to clear information than to surprises.
- Keep digital copies ready to share as soon as you go live.
- If disagreements arise about testing frequency or scope, note that annual bacterial testing is commonly recommended, and testing just before sale is strongly advised.
Preparing these items before you list shows buyers you care about transparency and safety. It can shorten contingencies, reduce back-and-forth, and protect your bottom line.
