Since we just moved in to this house, my husband suggested replacing all the locks. We don’t know if somebody has the duplicate to the house and might intrude anytime. I don’t want to feel sorry in the end, I mean I have the full trust in the previous owner, but I just want to make sure. We also would like to change knob handles and I found some I can say it is durable and long last. For now though we are still saving some for the repairs on this house. I mean we didn’t even pay the whole amount, thank GOD that the owner is okay with it, we paid him partially. I have so many things I would like to do for this house, but of course I am doing it one at a time.
