We had a fire in our kitchen (don't ask) and, even after we had a professional cleaning crew come in, the smoke odor lingered. My wife called Lawrenceville Fire Flood and Water Damage and they got the smell out--for real this time. They also gave us a lot of information about carcinogens found in smoke and soot. After their service, I feel my house is cleaner, I no longer smell the burnt ashy-type smell, and I feel more informed than before.
This company does what it says it'll do. For that alone, I'd recommend them, but they also gave good customer service and were attentive to our families needs and questions.
