You might already have air chamber shock absorbers, in which case you could recharge them: shut off the main, open all fixtures to drain the pipes, let it sit awhile, close the fixtures, turn on the main. See if that reduces the hammer, and then see how long it lasts.
Otherwise just install the screw-on hammer arresters at the washing machine and any other fixture that's causing water hammer:
