Personally I charge a little more than the norm, when it comes to doing deadwooding, for a variety of reasons.
Dead material is harder to cut with hand saw or chain saw, dulls blades quicker.
If your doing the entire tree crown it is going to mean a lot of limb walking to get dead stuff out on the ends.
Dead wood is hard and stiff, harder to work with than live branches.
Clean-up is nothing but one big mess that doesn't chip good, breaks up more, so you have more to rake and clean-up.
Ther is always more up there than you think there is, if you specefy for example five dead limbs to be cut, the customer sees one more, then another, can you get this one too, it goes on and ond on and the mess gets bigger. You will find out after awhile, what I'm talking about.
The biggest reason I charge more is your doing the more professional type arborist work. Especially if it is coupled with crown cleaning and thinning.
The competition isn't quite as stiff as it is with the removals. The people that request arborist work, have a concern for their trees, and the quality of care they recieve, price isn't a big issue compared to quality of workmanship. You have to get a feel for whose just shopping around and those who aren't.
Remember, your an arborist. not some boff with a chain saw and a ladder. Not everybody does the same quality of work in this business. Don't be afraid to charge the norm,and then some if the work is technical. Just don't get crazy and start charging double, you won't work then.
