Before and after photos of finished jobs, taken on a phone. Take the before shot before starting, which is the step most people forget. Small everyday repairs outperform large remodels, because most homeowners need small repairs and want proof you will show up for one.
Handyman work photographs better than most trades and almost nobody takes advantage of it. The reason is simple: the before shot has to be taken before the work starts, and by the time you remember, the rot is already out.
What to capture, in order of usefulness:
Ask permission before photographing inside someone's home. Most people say yes, particularly if you offer to keep identifying details out of frame.
Phone photos are fine. Stock photos actively hurt you, because homeowners have seen the same smiling contractor on forty other websites.
The Handyman BrandPack is ready to use, fully customizable, and done for you, so you get all the marketing assets you need.
