We recently had our house tented by Terminex. Upon completion the guy from the gas and electric company came to turn the gas back on.
He said he could not light the water heater beacuse the air vent was blocked, apparently caused by the tenting. We have left multiple messages with Terminex. They keep promising that someone will call us back, but after 5 days no one has.
They also promised to send someone out to the house, which was also a lie. I would definitely not recommend Terminex to anyone wishing to have their house treated for termites or for other service.
