The Risk

You Can’t See It.
You Can’t Smell It.

Radon is a radioactive gas that forms naturally from uranium decay in Alaska’s soil and rock. It seeps into homes through foundation cracks, sump pits, and floor gaps — then accumulates silently.

EPA Action Level: 4 pCi/L

Many Alaska homes test significantly higher. The national average is 1.3 pCi/L — Anchorage-area geology puts homes at elevated risk.

  • EPA-approved 48-hour short-term test
  • Accredited laboratory analysis
  • Written report with your pCi/L level
  • Mitigation contractor referrals if elevated
  • Bundle with home inspection — most popular option

Who Should Test

Every Anchorage Home.

Home Buyers

Test before closing. Elevated radon is negotiable — but only if you know about it.

Home Sellers

Testing before listing avoids last-minute surprises and builds buyer confidence.

Homeowners

Radon levels change. Renovations, new occupants, or shifting soil can all affect your reading.

Commercial Tenants

Ground-level offices and below-grade workspaces face the highest risk. Test before signing.

Home + Radon Bundle

Most buyers add radon testing to their home inspection. One call, one appointment. Larry places the device at inspection start and picks it up 48 hours later.

Process

How Radon Testing Works

1

Schedule

Call or book online. We place the EPA-approved test device at the lowest livable level of your home.

2

48-Hour Test

Short-term testing under closed-house conditions — the standard for real estate transactions.

3

Lab Analysis

Device is sent to an accredited laboratory for precise pCi/L measurement.

4

Written Report

You receive your radon level with context and mitigation guidance if the result is elevated.

Service Area

Where We Test for Radon.

A short-term radon test is two visits, not one — the device is placed, then retrieved 48 hours later. That makes distance a real constraint rather than a detail, so here is exactly where we test and where we don’t.

Anchorage Bowl

Core service area. Same-week scheduling in most cases, and the easiest to bundle with a home inspection.

Anchorage · Eagle River · Chugiak · Girdwood

Mat-Su Valley

Regularly served. Routine scheduling alongside Mat-Su home inspections.

Wasilla · Palmer · Big Lake · Houston · Meadow Lakes

Kenai Peninsula & Upper Susitna

Travel-dependent. Best arranged alongside a home inspection so the trip covers both visits — call to confirm timing.

Seward · Kenai · Soldotna · Homer · Talkeetna

Outside Southcentral Alaska

Fairbanks, North Pole, Delta Junction, Tok and the rest of Interior Alaska sit several hundred road miles from Anchorage, and communities off the road system are further still. We don’t schedule routine radon testing there, because the two-visit requirement makes it impractical to do well. Inspections in those areas are handled by request — see remote Alaska inspections or call (907) 223-3725 and we’ll tell you straight whether travel can be arranged.

FAQ

Radon Testing Questions

Yes. Alaska has elevated radon levels in many areas including Anchorage, Eagle River, and the Mat-Su Valley. Testing is the only way to know your home's radon level.

The EPA recommends mitigating levels at or above 4 pCi/L. Levels between 2–4 pCi/L should also be reduced if possible. The national average indoor level is 1.3 pCi/L.

Short-term radon tests take 48–96 hours. For real estate transactions, 48-hour short-term tests are standard and accepted by most lenders and buyers.

If your home tests above 4 pCi/L, a sub-slab depressurization system can reduce levels by up to 99%. Systems typically cost $800–$2,500. We can recommend licensed mitigation contractors in Anchorage.

Yes. We offer a Home + Radon bundle — the most popular option for buyers. The radon device is placed at the start of the home inspection and picked up 48 hours later. Call (907) 223-3725 to schedule.

Anchorage, Eagle River, Chugiak and Girdwood are our core radon testing area, along with Wasilla, Palmer, Big Lake and the wider Mat-Su Valley. Kenai Peninsula testing in Seward, Kenai, Soldotna and Homer is travel-dependent, as is Talkeetna and the upper Susitna Valley — a radon test needs two visits 48 hours apart, so distance affects what we can schedule. Call (907) 223-3725 to confirm your location.

Not on a routine basis. Fairbanks, North Pole, Delta Junction, Tok and the rest of Interior Alaska are several hundred road miles from Anchorage, and a short-term radon test requires placing the device and returning 48 hours later to retrieve it. We would rather say so plainly than take a booking we cannot serve well. For Interior and off-road-system properties, contact us about a by-request inspection and we will tell you honestly whether travel can be arranged.
