I am going to try and install 2 gable vents on the sides of a customer's home tomorrow for the 1st time to vent his attic. Did I mention I am not a carpenter? I have to figure out which of my power saws will be best to cut vinyl siding with, then figure out how to reattach the remaining siding to the house after cutting the square hole for the vent, then figure out how to attach the vent. The one side will be easy to do, as its over the garage, but the other side is about 24 feet in the air, and my longest ladder is only about 19 feet when fully extended! Its technically a 24 foot ladder, but they measure the 2 pieces when they are fully pulled apart, but when slid together and overlapping each other, the ladder is only 19 feet. Its kind of false advertising....
I've done this "figure it out as you go" method many times, and its always worked out, so I think this will too. As long as you can follow instructions, make good measurements, and have good, basic mechanical skills, it shouldnt be a problem to do this kind of thing I always say...... I've put floors into 3 attics, rebuilt the frame work and walls of my own covered patio and rebuilt the doors and sides of 3 good quality sheds. I own a landscaping company by the way..... might not sound that way though.
