Not unless that was an agreement you made with your mother in advance. It’s her home, and she has no legal obligation to transfer it to you. You may, however, have a legal claim for compensation for the services you provided. This type of claim is referred to by the Latin term quantum meruit. If you assert that claim, you may be able to work out some sort of transfer. Depending on the value of the services you provided and the value of the house, this may or may not involve its complete transfer to you.
