COMMON IAQ CONCERNS

Common Indoor Air Quality Problems in Massachusetts & New Hampshire

Homes throughout Massachusetts and New Hampshire can experience indoor air quality concerns related to seasonal humidity, moisture intrusion, ventilation, building materials, and modern construction practices.

✓

Limited Air Exchange

Tight homes can reduce natural air exchange and trap indoor contaminants.

✓

Humidity & Seasonal Moisture

Elevated humidity can contribute to comfort and moisture concerns.

✓

Roof Leaks & Ice Dams

Water intrusion can create hidden moisture conditions.

✓

Poor Attic Ventilation

Insufficient ventilation can contribute to heat, humidity, and moisture buildup.

New England Homes Can Present Unique Conditions

From historic homes to modern high-performance construction, indoor air quality concerns can vary based on moisture, ventilation, occupant activities, and recent renovations. If active moisture intrusion, visible microbial growth, musty odors, or suspected mold are present, a professional mold inspection may also be appropriate.

WHEN TO CONSIDER TESTING

When Should You Consider Indoor Air Quality Testing?

Indoor air quality testing may be helpful when odors, moisture, recent renovations, ventilation concerns, or other changes affect the indoor environment.

✓

Persistent musty, chemical, or smoky odors

✓

Unexplained respiratory irritation or indoor discomfort

✓

Recent renovations, new flooring, cabinetry, or furnishings

✓

Water intrusion, leaks, elevated humidity, or moisture damage

✓

Concerns about mold, VOCs, particulates, or other indoor contaminants

✓

Building Envelope Conditions

Air leakage, insulation, and building design can influence indoor environmental conditions.

✓

Combustion & Safety Concerns

Combustion appliances and related conditions may also be evaluated when appropriate.

Why Both Approaches Matter

Laboratory testing can identify airborne contaminants, while building science evaluation can help determine why those conditions may be occurring. When appropriate, both approaches are used together to provide a more complete understanding of the indoor environment.

Frequently Asked Questions

What does indoor air quality testing include?

Testing may include measurement of airborne contaminants such as mold spores, VOCs, formaldehyde, particulate matter, radon, and combustion gases, based on the specific concerns identified during your consultation.

Can high VOC levels occur after renovation?

Yes. New paint, flooring, adhesives, cabinetry, furniture, and other building materials can release volatile organic compounds (VOCs), particularly after renovation or new construction. Limited ventilation can allow these compounds to accumulate indoors.

Can basement humidity affect indoor air quality upstairs?

Yes. Moisture, odors, mold spores, and air from basements can migrate into upper living areas through stairways, wall cavities, ductwork, and other air pathways. Elevated basement humidity may also contribute to conditions that support mold growth.

Does attic ventilation impact indoor air quality?

Yes. Inadequate attic ventilation can contribute to excess heat, condensation, moisture accumulation, and mold growth. Depending on air leakage pathways between the attic and living space, these conditions may also affect indoor environmental quality.

Do newer homes experience indoor air quality problems?

Yes. Newer energy-efficient homes are often built with tighter building envelopes, which can reduce natural air exchange. Without adequate mechanical ventilation, VOCs, humidity, carbon dioxide, and other indoor contaminants may accumulate.

What is considered a normal indoor VOC level?

There is no single acceptable VOC level that applies to every indoor environment. VOC results depend on the specific compounds present, their concentrations, ventilation, occupancy, and potential sources. Testing provides measured data that can be evaluated against recognized environmental guidelines and laboratory reference information.

How long do VOCs remain elevated after renovation?

VOC levels may remain elevated for days, weeks, or longer depending on the materials involved, temperature, humidity, ventilation, and the rate of off-gassing. Indoor air quality testing can help determine whether VOC concentrations remain elevated after renovation or new construction.

Can poor ventilation increase carbon dioxide (CO₂) levels indoors?

Yes. Inadequate fresh-air exchange can allow carbon dioxide levels to increase as occupants breathe indoors. Elevated CO₂ can be an indicator of insufficient ventilation and may contribute to stuffiness and discomfort.

Can new construction or spray foam insulation affect indoor air quality?

Yes. New construction materials, including spray foam insulation, engineered wood products, adhesives, flooring, paints, and finishes, can release VOCs and, in some cases, formaldehyde during the off-gassing period. In tightly constructed homes with limited ventilation, these compounds may accumulate indoors. Indoor air quality testing can help measure VOCs, formaldehyde, and other environmental conditions.
