Syed explained the process, did a thorough job and they are very friendly and easy to deal with.
The mold removal team did a very good job. They were professional, arrived on time, and completed the work efficiently. The area was cleaned thoroughly, and I am satisfied with the quality of the mold removal. My only concern was that the final price was higher than the original quote once they arrived for the removal. While the work was done well, I would have appreciated more transparency about the additional costs beforehand. Overall, I am happy with the results and would recommend them for their quality of work, but I suggest confirming all costs in advance.
Our in-laws were in need of their services. Given their age and condition ASM came highly recommended. The co-ordinator was very courteous and advisd them of any precautions they needed to take before the treatment. Once Syed was on site, he investigated and advised them further. He was quick, friendly and thorough and delivered as promised. Would definitely recommend to any friend or family.
Ali, the inspector/coordinator, super friendly, well spoken, answered any questions we had. Syed, the technician, did a clean, efficient job removing the mold. We got the best quote and they completed with a report and warranty. Will use again.
