Our emergency crime scene cleanup process is designed for rapid, compliant response — controlled containment, professional cleaning, and prompt action to restore safe and secure environments after police clearance.
Our technicians begin by assessing areas impacted by cigarette and cannabis smoke odors. We identify odor absorption points in walls, ceilings, fabrics, furniture, and other porous materials to determine the most effective treatment approach.
A detailed hazard assessment is performed to identify contamination risks, establish safety protocols, and support a controlled and compliant crime scene cleanup process before remediation begins.
Using professional-grade odor removal methods, we treat smoke-affected surfaces, fabrics, and materials to neutralize odor-causing particles. This step targets odors embedded deep within porous materials.
Air filtration and odor control measures are prepared to help reduce airborne smoke particles, improve indoor air quality, and support effective cigarette smoke odor removal throughout the property.
We apply advanced deodorization techniques to address remaining odor traces throughout the space. This phase helps reduce residual smoke smells and improves overall indoor comfort and air quality.
Once treatment is complete, we review results and provide guidance on maintaining a fresh indoor environment. If additional treatment is recommended, we explain next steps clearly and transparently.
A fast and professional crime scene cleanup process helps reduce health and safety risks, prevent escalating property damage, and restore secure conditions as efficiently as possible.

Every hour matters after a crime scene has been cleared by authorities. Biological contamination and hazardous materials can pose serious health and safety risks if not addressed promptly. Delaying professional crime scene cleanup allows contamination to spread deeper into surfaces, increasing restoration costs and safety concerns.
Immediate crime scene cleanup removes hazardous contamination quickly, limits health risks, and helps restore safe, secure environments after police clearance.

We would definitely hire them again for our renovation needs and recommend them to everyone. TianaPosted on Mathew WhiteTrustindex verifies that the original source of the review is Google. 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.Posted on siddharth khannaTrustindex verifies that the original source of the review is Google. 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!Posted on Mark EsdaleTrustindex verifies that the original source of the review is Google. 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.
