The crew at AFI was outstanding! Work was completed in a professional and timely manner. Highly recommended!

This company is the best. Our home posed many challenges as it is 148 years old with additions of unknown ages. Mike K. and his team faced each challenge with grace and got the job done to perfection. Even with a 70 lb puppy, Milly bringing him toys all day. I highly recommend them!

The guys did a great job this morning with an extraction! Looking forward to calling them when we need to spray foam!
