If the cause of the contamination can be clearly identified, you may send samples to us. If not, our professional engineers will conduct an on-site investigation of the building and building materials using field equipment and document their initial findings. Once the source of contamination has been identified, samples of indoor air, building materials, or object surfaces will be collected and sent to a laboratory for analysis. We will analyze the samples using the most appropriate methods and evaluate their impact on the client. A written report containing a comprehensive assessment and recommendations for further action will be submitted to the you.
