Our basement flooded recently with the heavy rains in Southern Ontario. This made our existing mould problem significantly worse. Warren came in to give a quote on short notice on the weekend. After examining the situation and the strong odour that was spreading to the rest of the house, Warren offered to put up a containment barrier by himself and retrieve one of his HEPA air blowers/filters to help contain the mould and odour to the basement through negative air pressure. This was done without any commitment to further work at the time. Warren was reasonable and flexible with his pricing and timing to start - offering to start the next workday. The work involved removing all carpeting and underpadding, cabinetry, the majority of drywall, plastic walling in the washroom, and a bathtub, followed by mould treatment/cleaning. During the work, I did have to remind his team to seal off one of the ceiling vents, which they had missed/forgot. However, I did not experience any other issues, and his team was always punctual and on time for the days of the job. Warren's responsiveness (always answers calls or returns calls quickly), courteousness, and accommodation for small details set him apart from some of the larger and more reviewed mould remediation companies, and ultimately made the difference in choosing A1 Eco. I am very satisfied with my overall experience with A1 Eco, Warren, and his team.
