Add-on services

When you need each add-on — and when you don't.

Add-ons are where inspection companies quietly pad tickets. So here's our whole pitch in one rule: every add-on below carries a plain-English 'when you need it' and 'when to skip it.' We'd rather lose $165 today than your agent's referrals forever.

Bundle rule: each add-on after the first is $25 off.

Continuous radon monitor mounted on a tripod in a basement during a 48-hour test — The 48-hour continuous monitor — hourly readings, not a one-shot canister.

Radon test (48-hour monitor)

$165

Monitor set at inspection, collected 48 hrs later

We place a continuous radon monitor during the inspection and collect it about 48 hours later. You get an hourly graph, the overall average, and a plain-English page on what the number means. If the result is at or above 4.0 pCi/L, mitigation typically runs $800–$1,500 — a negotiable, fixable item, not a deal-breaker. We don't sell mitigation, so the number is just the number.

When you need it

Any home with ground contact — basement, slab or crawl space. Central Ohio sits in the EPA's highest-potential radon zone (Zone 1), and roughly one in three area homes we test reads at or above the 4.0 pCi/L action level.

When to skip it

Upper-floor condo units with no ground contact, or a home with an active, recently certified mitigation system you plan to keep running — re-testing is still cheap peace of mind.

Inspector feeding a scope camera into a floor drain while watching the live video screen — Camera in the line, recording the whole run to the city main.

Sewer scope (camera to the main)

$195

+45 min, video included

We run a self-leveling camera from the cleanout to the municipal tap, recording the whole run. You get the video file, footage markers for any offsets, bellies, root intrusion or breaks, and a severity call in the same language as the main report. It's the single highest-stakes add-on we offer for older streets.

When you need it

Homes 25 years or older, any yard with mature trees near the line, and any house with clay tile or Orangeburg pipe history — most of Columbus built before 1990 qualifies. A failed lateral is a $5,000–$15,000 repair you can't see from inside.

When to skip it

New construction with a builder-documented lateral video, or condo units where the association owns the line — we'll tell you before you pay for it.

Technician pointing a thermal imaging camera at a moisture-stained wall beside a window — Heat signatures flag what drywall hides — then a moisture meter confirms.

Thermal imaging survey (whole home)

$95

+30 min, images in the report

Every Datum inspector carries a radiometric thermal imager, and spot checks are always free. The survey add-on is different: a documented, room-by-room scan of exterior walls, ceilings below attics and every wet wall, with annotated images in the report. Thermal imaging shows temperature, not moisture — anything suspicious gets confirmed with a moisture meter before it's written up.

When you need it

Finished basements, homes with additions, past roof leaks or any stucco/EIFS cladding — heat signatures reveal missing insulation, hidden moisture and overloaded circuits before they show on the surface.

When to skip it

We already point the camera anywhere the visual inspection raises suspicion, at no charge. The paid survey is the systematic wall-by-wall pass with images documented in your report — skip it if the house is small, simple and dry.

Wood-framed craftsman porch with cedar shingle siding — the construction style where wood-destroying insect checks matter most — Older wood construction is exactly where WDI evidence hides.

Termite / WDI report

$135

+30 min, lender-format report

A licensed wood-destroying-insect inspection covering termites, carpenter ants and powder-post beetles, delivered on the standard report form lenders expect. We probe accessible sills, joists and grade-level wood and document conducive conditions (mulch against siding, wood-soil contact, moisture) even when no live activity is found.

When you need it

Required for VA loans and requested by many lenders. Smart for any home with wood-to-soil contact, prior treatment history, or age over 40 years — subterranean termites are active throughout central Ohio.

When to skip it

Recently treated homes with a transferable termite bond — bring the paperwork and we'll verify what's covered instead of re-charging you.

Mold & air-quality sampling

$325

Lab results in 3–5 business days

Two calibrated air samples (one interior, one exterior control) analyzed by an independent lab, plus surface samples where growth is visible. Results in 3–5 business days with spore counts by species and a plain-English interpretation. We don't do remediation, so the lab report is the product — not a sales funnel.

When you need it

Visible suspect growth, a musty smell, a known flood or leak history, or a household member with respiratory sensitivity. Sampling puts a species and spore count behind what your nose already suspects.

When to skip it

Honestly? Most homes. If we see no moisture evidence and you have no symptoms or history to chase, we'll tell you to keep the $325. Sampling without a reason mostly buys anxiety.

For sellers

The pre-listing inspection

Same scope, same severity codes, same report — commissioned by the seller before the sign goes up. You fix the cheap surprises on your own schedule, disclose the rest with evidence attached, and take the inspection contingency's biggest ambushes off the table.

Priced straight from the standard fee table ($315–$595+ by size) — no seller surcharge
A repair-priority list: what to fix before listing vs. what to simply disclose
Re-inspection of completed repairs, $125 flat, documented in an updated report
Honest caveat: buyers may still bring their own inspector — ours removes surprises, not contingencies
