Basically the ancient vaastu texts do not deal with vaastu corrections by alternative methods. They advocate in all such cases structural correction to set right the defects.
The performance of rituals like Vaastu Pooja, Vaastu Homa and the like are mentioned to get the blessings of the plot organism which goes without saying that the house, in the first place, should be as per vaastu.
I have come across several defective houses that has put the occupants to misery in spite of the fact that before entering the house all the rituals were performed in a grandiose manner as per the texts. It is also true that if one were to occupy a house built as per vaastu even without performing any of these poojas or homas, one will still enjoy the benefits of being in a good vaastu house. Rituals have therefore no part to play in vaastu.
Any problem due to vaastu can only arise only if the Northeast force in the plot is weak. If the Northeast is strong in spite of defects in other sectors, the occupants are unlikely to suffer the effect of such vaastu defects.
