Sick building syndrome is the name for a frustrating pattern many New Jersey business owners eventually run into. Employees feel unwell at work, with headaches, irritated eyes, or constant fatigue, yet the symptoms fade soon after they leave the building. This guide explains what sick building syndrome is, what causes it, and the practical steps NJ offices can take to fix it for good.
What is sick building syndrome
The U.S. Environmental Protection Agency uses the term sick building syndrome, or SBS, to describe situations where building occupants experience acute health and comfort effects that appear linked to time spent in a building, but no specific illness or cause can be identified. The complaints may be concentrated in one room or wing, or spread throughout the entire building.
The key detail is that symptoms improve when people leave the building. That pattern separates SBS from a seasonal cold making the rounds or an individual health issue. According to a World Health Organization committee report cited by the EPA, up to 30 percent of new and remodeled buildings worldwide may generate excessive complaints tied to indoor air quality.
For office buildings across Morris County and the rest of New Jersey, many of them decades old and sealed tight for heating and cooling efficiency, this is not a rare problem. It is a building maintenance problem, and it is fixable.
Sick building syndrome vs building related illness
The EPA draws a useful distinction between the two. With building related illness, a doctor can diagnose a specific condition, such as an infection or an allergy, and trace it to an identifiable contaminant in the building. Symptoms often include cough, fever, chills, and muscle aches, and they may not fade after people leave.
With sick building syndrome, no single cause can be pinned down, and relief comes quickly once occupants step outside. Both situations deserve attention, but SBS is the one that tends to linger for months because nothing shows up on a standard checkup.
Common symptoms to watch for
Sick building syndrome shows up as a cluster of complaints across multiple employees rather than one person feeling off. The EPA lists these as the most common indicators:
- Headaches and dizziness
- Irritated, dry, or watery eyes
- Nose and throat irritation
- Dry cough or tight chest
- Dry, itchy skin
- Fatigue and difficulty concentrating
- Nausea
- Increased sensitivity to odors
If several people on your team report the same symptoms, and those symptoms ease up on weekends or vacations, the building itself deserves a closer look. Track when and where complaints happen. Patterns by floor, room, or time of day are valuable clues.
What causes sick building syndrome
There is rarely one single culprit. The EPA points to four contributing factors that often work in combination.
Inadequate ventilation
When HVAC systems do not bring in enough outdoor air or distribute it poorly, contaminants build up indoors. This is one of the most common drivers of SBS, especially in buildings that were sealed up to save energy. Blocked vents, clogged filters, and dust-caked returns make the problem worse.
Chemical contaminants from indoor sources
Adhesives, carpeting, upholstery, manufactured wood products, copy machines, and some cleaning products all release volatile organic compounds, or VOCs. Harsh conventional cleaning chemicals can add to the load. This is one reason the team at Supreme Office Cleaning uses natural, non-toxic products whenever possible, so the cleaning itself never becomes part of the problem.
Chemical contaminants from outdoor sources
Vehicle exhaust from parking garages and loading docks, plumbing vents, and building exhausts can get pulled into a building through poorly placed air intakes, windows, and other openings.
Biological contaminants
Mold, bacteria, pollen, and dust mites thrive in ducts, humidifiers, drain pans, water-stained ceiling tiles, carpets, and upholstery. Biological contamination can cause coughing, chest tightness, allergic reactions, and more. If your building has had leaks or standing water, this factor moves to the top of the list. Our guide on office mold prevention covers this risk in depth.
Why summer makes it worse in New Jersey
New Jersey summers bring heat and heavy humidity, and that combination is hard on office buildings. Air conditioning systems run constantly, windows stay shut, and the same air keeps recirculating through the space. Any dust, mold spores, or VOCs in that air keep cycling past your employees all day.
High humidity also feeds biological growth. Condensation around vents, damp carpet edges, and moisture in restrooms and kitchens create ideal conditions for mold and bacteria. A building that felt fine in April can start generating complaints by mid July.
That makes summer the right time for NJ businesses to be proactive. Deep cleaning carpets and upholstery, keeping restrooms dry and sanitized, and clearing dust from vents and high surfaces all reduce the contaminant load your HVAC system recirculates.
How professional cleaning helps
Cleaning cannot replace HVAC repairs or ventilation upgrades, but it directly attacks two of the four causes of sick building syndrome: chemical and biological contaminants. A consistent commercial cleaning program removes the dust, allergens, and residues that build up in any busy workplace before they become an air quality issue.
Here is what a targeted program looks like in practice:
- Regular deep dusting. Dust on vents, blinds, ceiling fixtures, and high shelves gets recirculated every time the HVAC kicks on. Scheduled office detailing removes it at the source.
- Carpet and upholstery care. Soft surfaces trap VOCs, allergens, and moisture. Periodic extraction cleaning pulls contaminants out instead of letting them accumulate.
- Restroom and break room sanitation. These are the dampest rooms in the building and the most likely to harbor bacteria and mold. Daily attention keeps them dry and hygienic.
- Non-toxic products. Cleaning with natural, low-VOC products improves results without adding new chemicals to your indoor air.
- Trash and food waste removal. Overnight garbage is a steady source of odors and bacteria, especially in summer heat.

Steps to take if you suspect SBS in your office
If complaints are stacking up, work through the problem methodically:
- Document symptoms, locations, and timing across your team.
- Walk the building and look for water stains, visible mold, blocked vents, and dust buildup.
- Have your HVAC contractor inspect ventilation rates, filters, drain pans, and ductwork.
- Remove or isolate obvious sources such as stored chemicals, old carpet, or off-gassing furniture.
- Schedule a deep cleaning that covers carpets, upholstery, vents, and high surfaces.
- Reassess after a few weeks and keep a recurring cleaning schedule so gains hold.
