Radon Questions, Answered Plainly

Most professional radon tests run for 48 hours of active monitoring, plus a few minutes for setup and pickup. Full results are usually delivered as a written PDF report within 3 business days of scheduling.

No. You can live normally during the 48-hour test. You just need to follow EPA "closed-house conditions," which means windows stay closed (HVAC running normally is fine). You don't need to stay out of the basement or change anything about your routine.

Closed-house conditions are the EPA standard for short-term radon testing: windows closed and external doors used only for normal coming and going, both for 12 hours before the test and during the full 48 hours of the test. Your HVAC, range hood, and bathroom fans can run normally.

Very. Continuous radon monitors calibrated to EPA standards are considered the gold-standard short-term measurement method. For homes near the 4.0 pCi/L action level where the homeowner wants extra confidence, we offer follow-up 90-day passive testing as well.

Yes, and they have their uses, but for a meaningful first reading or any real estate transaction, professional testing is the way to go. Hardware store kits vary in accuracy, can't detect tamper attempts, and produce a single average rather than hourly readings.

The EPA recommends retesting every 2 to 5 years for homes that initially tested under the action level, after any major renovation or HVAC change, and after any foundation work. For homes with mitigation systems, we recommend annual retests to confirm the system is still performing.

Most installations are completed in a single day, usually 4 to 6 hours of work. We arrive in the morning, install the system, seal foundation entry points, mount the fan and manometer, and walk you through how it works before we leave.

Modern radon fans (we use Festa and Radonaway) produce roughly 50 decibels at the fan housing, about the volume of a quiet refrigerator. Because the fan is mounted outdoors on an exterior wall, you typically can't hear it inside the house at all.

Almost none. A typical radon mitigation fan draws 60 to 90 watts (less than a single old-style incandescent light bulb). Annual electrical cost is usually $40 to $80 depending on local utility rates.

It shouldn't. We route systems to minimize visual impact, use color-matched materials for exterior runs, and route interior runs through closets and unused chase space. The aesthetic is part of the quote conversation, not an afterthought.

The PVC pipe and fittings last indefinitely. The fan, the only moving part, has an expected lifespan of 10 to 15 years and is covered under a 5-year warranty on every system we install. Replacing a fan when it eventually wears out is a 30-minute job.

Yes. Every Safe Space Radon mitigation install is guaranteed to drop levels below 4.0 pCi/L, verified with a post-mitigation test you receive in writing. If the post-test reads at or above 4.0, we return at no cost and adjust the system.

Typically the buyer, as part of their inspection contingency. Some sellers proactively test before listing to avoid surprises during the inspection period. Either way, the cost is modest relative to what's at stake in the deal.

This is negotiable. In our experience across Northeast Ohio, sellers typically cover mitigation when the reading is above 4.0 pCi/L, often as a credit at closing rather than work done before the deal closes. Your real estate agent can advise on what's customary in your specific market.

If you call us with the closing date, we work backward from it. Most mitigations can be installed within a week of an accepted quote. The post-mitigation test takes another 48 hours, so the practical minimum is 10 to 14 days from the call to the verified result.

Yes, with a properly worded escrow holdback or buyer credit. We can provide an estimate the title company will accept. Many closings happen this way: the home transfers, the system is installed shortly after, the holdback releases when the post-test confirms compliance.

Our standard 48-hour test is $150 flat fee, which includes drop-off, monitoring, pickup, and the written report. Real estate transaction testing is the same price.

Ask about financing, not publicly offered, but can be offered on a per case basis. Many homeowners find that mitigation pays for itself by adding to the home's value at resale, especially in Zone 1 markets where buyers expect documentation.

Generally no for a primary residence, but some homeowners in specific tax situations (medical necessity, rental property, home office) may be able to deduct part of the cost. Talk to your accountant for specifics.

Seven counties: Cuyahoga, Summit, Lake, Lorain, Stark, Ashtabula, and Erie. That covers Cleveland, Cleveland Heights, Shaker Heights, Lakewood, Akron, Mentor, and most surrounding suburbs. If you're nearby but not on the list, call us anyway.

Yes, both. NRPP for measurement and mitigation, NRD for ongoing professional standards. We're also licensed by the Ohio Department of Health. License numbers are listed on our About page.

Yes. Every mitigation install comes with a 5-year warranty on the fan and components, and our performance guarantee (below 4.0 pCi/L verified in writing) is built into the quote.

Three things: the owner does the work (no subcontracting), we live in NE Ohio (not a regional dispatcher), and we answer the phone. The technical work itself is comparable to any reputable certified mitigator. The experience of working with us is usually what people notice.
