We bought a house, and it was obvious that the previous owners had pets. Like.... a LOT of pets. We were worried that the house would smell like urine every time it got humid. It's been 4 months, and I can safely say that Jul from Ductworks took incredible care of us. He spent an entire 10 hour day brushing, vacuuming, fogging / sterilizing every corner of our ducts... we both were wondering if we would have to make up the guest bed! There is no trace of the pet smell, and our 27 year old house feels brand new. Thank you, Jul!
