In-person measurement for Denver houses, condos and high-rise apartments, from a Front Range specialist based in Fort Collins.
FieldWise EMF Consulting tests Denver houses, condos and apartments for wireless RF, AC magnetic and electric fields, dirty electricity and lighting. A third of Denver’s homes are in buildings of 20 or more units, so readings separate your own sources from your neighbors’. Founder Cameron Castaneda measures in person against Building Biology SBM-2015 guidelines. Most Denver homes, from older houses to high-rise condos, start with the Foundational Assessment, $850, which includes a written room by room report and an action plan call.
Denver Specifics
Mostly, where the fields come from. In Denver, 32.3 percent of homes sit in buildings with 20 or more units, against 11.9 percent in Fort Collins, according to the US Census Bureau. In a building like that, wireless signals reach a bedroom from above, below and both sides, and the electrical room and the bank of meters may be on the other side of a wall.
None of that shows up in your own router settings. Measuring each room tells you how much of what you are living with is yours to change, and where moving the bed or the desk a few feet does more than any device would.
Routers, mesh points and smart speakers in the units around yours all add to the RF in your rooms, measured as power density in microwatts per square meter (µW/m²). The report separates sources inside your home from those arriving through shared walls and floors.
Instrument: Safe and Sound Pro 2 RF analyzerWhere a building’s meters, panels and risers are grouped together, the current through them produces AC magnetic fields that pass through walls. A unit beside the electrical room can read very differently from one down the hall, which is why the bedroom wall is measured on its own. If your unit shares a wall or floor with the building’s electrical room, or your house sits near a power line, substation or transformer, the 24 Hour Infrastructure Assessment logs magnetic fields for a full day and night, because those fields rise and fall with how much power the building and neighborhood are using.
Instrument: Gigahertz Solutions NFA1000, 3-axisThe City of Denver permits small cell antennas on existing utility and streetlight poles and on new poles in the right of way, and the city describes each one as serving a much smaller area, one to two blocks. A street-facing room is measured separately from one at the back of the building.
Instrument: Safe and Sound Pro 2 RF analyzerOlder Houses
Denver’s houses are among the oldest on the Front Range. 16.9 percent of the city’s homes were built before 1940, against 4.6 percent in Fort Collins (US Census Bureau), and Denver has 60 historic districts and 371 individual landmarks. A century-old house has usually been rewired in stages, and the joins between old and new are where wiring errors turn up.
Houses from before 1940 were often wired with knob-and-tube, where the two conductors run separately, inches apart, instead of side by side in one cable. Separated conductors cancel each other’s magnetic field less well, so any circuit still running that way is worth a reading in milligauss (mG).
Panels replaced, basements finished, kitchens moved: each change adds wiring. A wiring error that sends current home along the wrong path leaves a magnetic field behind, and a room-by-room reading is how it gets found. Our guide to wiring errors in older homes explains more.
Older wiring is not always grounded, and ungrounded wiring tends to carry stronger AC electric fields, reported in volts per meter (V/m). They matter most where you spend hours at close range, so the bed is measured first.
Every finding goes into the written room by room report, with SBM-2015 comparisons and prioritized next steps, including the ones an electrician would handle and the many that cost nothing.

Client Review
“We recently had Cameron with Fieldwise EMF Consulting perform a full EMF assessment of our home in Arvada, Colorado, and the experience was well worth it. He thoroughly tested everything from our bedrooms and living spaces to our Wi-Fi router, cell phones, and wireless devices, then took the time to clearly explain the results and answer all of our questions.
What stood out most was that Cameron didn’t use fear tactics but he provided practical, realistic recommendations to reduce EMF exposure and create a healthier home environment. We left with clarity, peace of mind, and a clear plan moving forward. If you’re looking for EMF testing, EMF consulting, or a home EMF inspection in Colorado, I highly recommend Fieldwise EMF Consulting.”

Common Questions
How much does EMF testing cost in Denver?
Most Denver homes, houses and condos alike, start with the Foundational Assessment, $850. It measures all four types of EMF (wireless signals, magnetic fields, electric fields and dirty electricity) plus your lighting, and includes a written room by room report, a prioritized action plan and an action plan call. If your home is near a power line, substation or transformer, the 24 Hour Infrastructure Assessment, $1,450, logs your home for a full day and night. Lighting only? The Home Light Reset is $350. Buying a home? The Pre-Purchase Inspection is $500. Step 1 for every option is a free 15 minute call to confirm the right fit for your address.
Can you test a unit in a high-rise building?
Yes. The assessment covers your unit room by room, and the report shows which readings come from inside it and which come from neighboring units, the building’s electrical equipment or the street. Only the rooms you have access to are measured, so common areas are left out unless the building agrees.
How can I tell whether my Xcel meter is a smart meter?
Xcel Energy says the meter model number on a smart meter starts with I2Y or D2Y, and that its smart meters communicate by radio. Xcel also offers a non-communicating meter for a monthly manual-reading charge, explained on its smart meter page. A reading at the meter and in the room behind it shows what the meter adds in your home, and our smart meter EMF guide covers the rest.
Can you assess a Denver home before we purchase it?
Yes. The Pre-Purchase EMF Inspection, $500, fits inside your inspection period. In about 2 hours it measures wireless signals, magnetic and electric fields, dirty electricity, wiring and grounding problems, any solar equipment, and nearby power lines, transformers and cell sites. Your written report arrives in less than 3 days and sorts every finding into easy fixes, bigger fixes (with a rough cost range) and findings that come with the property. We go through it together on a call before your deadline. In an older Denver house, it is also the first look at how the wiring behaves. Book as early in your inspection window as you can.
Is EMF testing a medical or diagnostic service?
No. We make no medical claims and cannot diagnose or treat any condition. We measure what is present in your home, compare it against precautionary Building Biology SBM-2015 guidelines, and give you practical, prioritized reduction steps.
