We had birds nesting in our bathroom vent. One came into the bathroom and the other got caught in the fan and died.We removed the fan and the birds and had Summit Environmental Solutions come out to clean out the vent. Ernie came out and was very friendly explaining what needed to be done. He ended up replacing the vent, putting a cover on the outside of the house, and even replaced the fan and cover that we removed in the bathroom. His work was great and I was surprised by how quickly he was done. We would definitely use them again if needed. I would highly recommend Ernie!
