Our 200+ year old house was a heating/air conditioning sieve as well as home to squirrels, chipmunks and God knows how many mice. Exterminators' extensive efforts over years for the previous owners did little good and upstairs rooms were always cold, no matter the thermostat settings. Brad and his team, working diligently and efficiently removed the remains of the varmints and sealed off their various entryways -- even over the uneven granite slabs in the basement. Since we are new to the house, I can't compare heating bills to give a percentage reduction, but the home is now warm and snug in the cold and the scampering of little feet behind the walls is gone. Can't recommend them highly enough. read more
