The entry door from the garage, already has a spring loaded hinge and it closes. But the issue is, it shuts very hard. I tried to adjust the spring, and now it almost goes to the closing position but does not latch.

I did notice at my friends house, his builder also installed the spring hinges, very similar to what I have, but his door closes slow, and latches too, much like a door closer.

What can I do to get my door to not do a loud shut, but do a slow close, and still latch. Please help.
