“I don't know what I would have done without North State Pure Maintenance. Once it was discovered there was a mold issue I called and they called back in less than 5 hours (I called in the middle of the night due to the severity of the mold once it was found) with a time they planned to come and treat entire property in less than 1 day wait time. Immediately the air quality improved and the two technicians that arrived were both friendly, sympathetic towards me in the situation and VERY thorough. They ensured the safety of the home with a follow up call to eradicate any remaining mold spores and left behind filters that would catch any remaining spores from circulating in air Vents. WOW. Above and beyond. Is there a 10 star button on here??!!”
