Why Buildings Here Have a Harder Time

The Four Corners puts two loads on a building that most of the country does not carry at the same time. Spring wind drives fine soil into everything, and fire season pushes smoke across the region for weeks at a stretch. Buildings get sealed against both, which cuts outside air exactly when the inside air needs it most. The EPA has long noted that people spend roughly 90 percent of their time indoors, and that indoor concentrations of some pollutants run two to five times outdoor levels. In a building with an undersized outside-air setting and a return path nobody has looked at since it was commissioned, that gap gets wider.

Most commercial IAQ calls do not start with a reading. They start with a person — a tenant, a teacher, an employee — saying the air is wrong. The job is to turn that into something measurable.

What DEKON Measures

Direct-reading instruments on site, laboratory analysis when the findings call for it.

Airborne particulate
PM2.5 and PM10 at occupied-zone height. This is the measurement that tracks blowing dust, wildfire smoke infiltration, and construction dust carried into occupied space.
Carbon dioxide
Used as a ventilation indicator against occupancy. High CO₂ in a conference room is a ventilation finding, not a toxicity finding, and it usually explains the complaint.
Temperature & relative humidity
Logged at fixed points. Humidity trends flag a moisture problem weeks before anything is visible on a wall or a ceiling tile.
Volatile organic compounds
Screening for solvent, adhesive, fuel and cleaning-product vapors, with laboratory confirmation where a specific compound needs to be identified rather than detected.
Carbon monoxide
Combustion appliances, attached garages, loading docks, and equipment running near an intake. Checked whenever a combustion source shares a building with occupied space.
Ventilation & airflow
Outside-air delivery, return paths, filtration in place, and pressure relationships between spaces. ASHRAE Standard 62.1 is the usual ventilation reference for commercial buildings.

How an Assessment Runs

From the complaint to the report

The complaint decides where the readings get taken.
  1. Intake. What the symptom is, which part of the building, what time of day, how many people, and what changed recently. A renovation, a new tenant, a roof repair, or a season turning over is often the whole answer.
  2. Walkthrough. The occupied space and the mechanical systems serving it — intakes, returns, filter condition, obvious moisture, and anything stored or operating near an air path.
  3. Baseline readings. Direct-reading measurements at fixed points agreed with you, recorded so later visits compare against the same locations instead of new ones.
  4. Sampling where it is warranted. Laboratory samples are collected under chain of custody and submitted to an accredited laboratory — but only where the walkthrough and the readings justify the cost.
  5. Written report. Readings, what they indicate, what to correct, and what does not need correcting. Plain enough to forward without a translator.
  6. Re-check. After a correction is made, the same points get read again so there is a before and an after on file rather than an assurance.

Where This Work Happens

Office and multi-tenant buildings where one mechanical system serves several leases and complaints land on the property manager. Schools and tribal and municipal facilities, where the report has to stand up in front of a board or an agency. Clinical and dental space, where air handling is part of the standard of care. Hotels, retail, and restaurants, where an odor becomes a public review overnight. And occupied buildings under renovation, where the question is whether construction dust is reaching the people still working in the building.

If the finding turns out to be mold or moisture, DEKON is licensed to do the remediation as well as the testing — see mold remediation, testing and indoor air quality. If you would rather keep the testing independent of any removal work, say so up front and the testing gets scoped on its own.

Ongoing Monitoring — IAQ Shield

A single assessment answers a question at one point in time. For buildings that want a record rather than an answer, IAQ Shield is DEKON's scheduled program: monitoring visits on a set interval, a written report every visit, priority response when a reading moves or a complaint comes in, and a baseline to measure against year over year. It is sold by building. Call for a walkthrough and a scope before anything is quoted.

Common Questions

What does a commercial indoor air quality assessment actually include?

A walkthrough of the occupied space and the mechanical systems serving it, direct-reading measurements of carbon dioxide, airborne particulate, temperature and relative humidity at fixed points, a look at outside air delivery and return paths, and any laboratory sampling the findings justify. The deliverable is a written report with the readings, what they mean, and what to do about them — not a stack of lab sheets with no interpretation.

What does a high carbon dioxide reading in an office mean?

Carbon dioxide is used as a proxy for how much outside air a space is getting relative to how many people are in it. At the concentrations found in offices it is not usually a toxicity problem. A high reading points at underventilation, and underventilation is what makes a room feel stuffy and concentrates everything else in the air along with it. ASHRAE Standard 62.1 is the ventilation reference commonly applied to commercial buildings.

Can DEKON test a building after a renovation before people move back in?

Yes. Post-renovation and post-construction air testing confirms that construction dust, and anything disturbed during the work, has been cleaned up before the space is reoccupied. DEKON also performs pre- and post-abatement clearance air monitoring on asbestos and lead projects, so a building that needed abatement during the renovation can be cleared and re-tested by the same crew.

Does DEKON do indoor air quality work on schools, tribal and government facilities?

Yes. DEKON is SAM.gov active (CAGE 1A8J1, UEI NARD6L7LPW3) and registered with the Navajo Nation ONTC, and performs a meaningful share of its work on Navajo Nation trust and allotted land. Gross receipts tax treatment on trust land is applied and documented correctly rather than guessed at, and reports are written to be handed to a board or an agency without translation.

An employee is complaining about the air. Where does DEKON start?

With the complaint. What the symptom is, where in the building it happens, and when it happens — that is what decides where the readings get taken. Sampling everything everywhere produces a thick report and no answer, and it costs more. DEKON starts from the complaint and works back toward the mechanical system that explains it.

What credentials does DEKON hold for indoor air quality work?

NM Contractor License #417265 with the GS-29 Asbestos, Lead & Mold Abatement and GB-98 General Contractor endorsements, EPA ID NMR00032243, AHERA Contractor Supervisor certification, 40-hour HAZWOPER with current annual refreshers for all field personnel, and active SAM.gov registration (CAGE 1A8J1, UEI NARD6L7LPW3).
