Installed 3 pest barricades to replace the existing ones on the side of the home. Vent covers were all on one side of the home. Customer wanted them replaced due to noise. He wanted flap-less vent covers to get ride of the tapping noise from the flaps. Vent covers are secure to the home. The third cover the customer received was wrong design. He will order the right one and get back to us to come finish it. Customer prepaid for final cover install.
