Dec 2020 our carpets were cleaned by this company. Within an hour of them cleaning, which we noticed were very wet, the smoke/carbon monoxide detector went off on the main floor, and then approx 8 hours later the detectors on the upper floor and basement went off. When we notified the Peter CARPET company and asked them what chemicals they used to clean the carpets, they took no responsibility. We ended up having to buy 3 NEW Detectors, for approx $200.00. It was an expensive carpet clean.
