Installing the trim on your shed is definitely not the hardest task you’ll have to deal with when building your shed, but a focused attention to detail will go a long way. A bad trim job will not be catastrophic for your shed, but it can attract all the attention away from the hard work you poured into the other aspects of your build. On the flip side, a great, detailed trim job can elevate your shed’s look drastically giving it a refined and clean appearance.
