The trees for privacy cost between $50.00 to $100.00 each depending on the species of trees you buy.
So if you install the trees yourself for privacy it will just cost you the amount per tree and your time to put the trees in.
If you hire someone to plant the privacy trees for you the cost for labor is usually around $38.00 per hour but cost can vary depending on who you hire to plant the trees.
So there's no way to say for sure what the cost will be to plant privacy trees on your property since it will depend on how many trees you need planted and the hourly charge of the company or people planting the trees.
But you can expect to pay between $300.00 to $1,000.00 and maybe more to have privacy trees planted in your yard.
