PROFESSIONAL AIR QUALITY TESTING

UNDERSTANDING WHEN & WHY Air quality testing IS IMPORTANT

Indoor air can contain hidden pollutants that affect your comfort, health, and indoor environment. Professional air quality testing helps identify airborne contaminants, moisture-related issues, and ventilation concerns before they become larger problems. Below are some of the most common indoor air quality concerns we test for.

Mould Spores

Airborne mould spores can circulate throughout your property and may indicate hidden mould growth behind walls, ceilings, or flooring.

Allergens

Dust mites, pollen, pet dander, and other allergens can reduce indoor air quality and contribute to allergy symptoms year-round.

Volatile Organic Compounds (VOCs)

Chemical emissions from paints, flooring, furniture, cleaning products, and building materials can impact indoor air quality.

Excess Humidity

High indoor humidity encourages mould growth and can create unhealthy indoor conditions if left unaddressed.

Poor Ventilation

Insufficient airflow can allow pollutants, moisture, and airborne contaminants to accumulate inside homes and commercial buildings.

Combustion Pollutants

Carbon monoxide, combustion by-products, and other airborne pollutants from fuel-burning appliances may require professional assessment.

What we do

Full-Spectrum Air Quality Testing Services

Our air quality testing process is designed for accuracy, clarity, and reliability — from initial indoor assessment and air sampling to laboratory analysis and clear reporting. We focus on evaluating indoor air conditions, documenting findings, and providing objective results to support informed decisions.

Initial Indoor Air Assessment

We begin with a detailed assessment of the indoor environment, reviewing areas where air quality concerns may exist. Our inspectors evaluate general conditions, occupant concerns, airflow patterns, and indicators that may affect indoor air quality.

Ventilation & Environmental Review

We begin with a detailed assessment of the indoor environment, reviewing areas where air quality concerns may exist. Our inspectors evaluate general conditions, occupant concerns, airflow patterns, and indicators that may affect indoor air quality.

Indoor Air Sample Collection

When appropriate, we collect indoor air samples using industry-approved methods. Sampling locations are selected based on assessment findings to help accurately evaluate airborne particles and overall air quality conditions.

Outdoor Air Sample Collection

Outdoor Air Sample Collection helps establish a baseline for comparing indoor and outdoor air quality. By analyzing outdoor air samples, we can identify airborne contaminants and determine whether indoor air quality issues are coming from inside or outside the property.

Laboratory Analysis & Result Verification

Collected air samples are submitted to accredited laboratories for analysis. This step helps identify airborne particle levels and other indicators, providing reliable data to support clear and accurate conclusions.

Clear Reporting & Next-Step Guidance

Review the results and provide a clear air quality report outlining findings, observations, and relevant insights. Our goal is to help property owners understand indoor air conditions and consider appropriate next steps, without obligation for additional services.

A professional air quality testing process provides clear insight into indoor environments and helps reduce uncertainty when addressing potential air quality concerns.

I had googled for heavy duty cleaning that was needed for my Brother, (has some physical issues) I supplied them with pictures. They sent me a quote & the job was scheduled immediately as it was time sensitive. I met the GTA Gentleman @ the front door of my brother’s condo.

Nijen's team replaced and build a privacy wall on our back deck last Friday. They were professional, and efficient and we couldn't be happier with the end result. Thank you to Nijen and his team. We would definitely hire them again for our renovation needs and recommend them to everyone. Tiana

I engaged First On Site as a preferred vendor through my insurance provider following an unsatisfactory experience with another restoration company. Understandably, I approached the process with some hesitation. From the outset, the team at First On Site demonstrated exceptional professionalism. They maintained clear and consistent communication, keeping me informed of all timelines and progress updates. Their responsiveness and attention to detail far exceeded my expectations. Upon arrival, the crew began work immediately and remained focused and diligent throughout the day. Their efficiency, professionalism, and respect for my property were commendable. Additionally, the team effectively liaised with my insurance company, ensuring the scope of work was completed exactly as described and to a high standard. I would not hesitate to recommend First On Site to anyone requiring disaster management or restoration services. Their commitment to quality and client satisfaction is truly exemplary.

I called them at 7 am for an emergency basement pipe burst leakage and they sent out a crew within a couple of hours who knew exactly what needed to be done. They documented the damage thoroughly for insurance purposes and I faced no trouble. The team at GTA are professional and helpful. Totally recommend!

After a ice storm related basement flood the GTA team showed us what service meant!. They were here very quickly, with the proper drying equipment and some great staff members. They removed old carpeting/under padding and the bottom 12 inches of drywall from the affected flood area, installed and left drying machines, were back in a week to repair the drywall. We could not have asked for a better job, very glad we chose them.
