This is sort of what I was going to get at. To Lawnbrother, what is the name of your business? Is it addreswsed with a "Landscape" or "Landscaping" and lawn maintenance?
For many, decks fall under the realm of landscaping. There are MANY landscapers that build decks along with doing hardscapes and patios. We have done decks in the past on renovations and complete installations. It's all part of the package. We have also subbed out this sort of thing, as well, but I was just using that as an example of my point. It is completely understandable for someone to inquire about deck work with a landscape company.
Thank you, Dad - for always being the dad that you were. You truly are my hero. You always were.
