I wasn't there for the entire process so I'm not sure about everything they did but I know there was supposed to spray a few different places throughout. What kept me from giving them five stars was I have a beam in my living room and they said they were going to spray it but as far as I know it never happened, so I thought that was a little odd. Other than that I assume they did everything they were supposed to do. The guys were very nice and I had no problems with them at all.
