Almost all work can be done by the do-it-yourselfer with a few basic tools.
The cost savings and job satisfaction can both be high. If you take the trouble to do the job properly, the results should be excellent. Make sure you consult any available installation guides and video tutorials carefully before you begin to familiarize yourself for the task at hand.

Some types of retrofit are best done by a contractor with tools and experience, or, if you prefer, have someone do the work for you, like DIFM (Do-It-For-Me). You are far more likely to have excellent work done if you choose a contractor carefully and take an active interest in the work performed. the more you know, the better. This is especially important if you are hiring a contractor to do general renovations and you want to include energy-efficiency as part of the work.
It is what it is, but it will become what you make it.
