How much to charge for drywall mud and tape?
If you are experienced at it, estimate how long you think a job will take. Determine how much you are going to charge on an hourly basis. Multiply the number of hours you think it will take by your hourly charge. Add in for travel time, transportation expense, insurance, possible callbacks, and materials with a chosen markup. Total them up and present your proposal. On bigger jobs, you could quote a price per square foot, but be careful…make sure you look at the job first to assess the conditions.
