According to EA and thier support site, it should revert back to non-decaying status after 24 hours from the account reactivation time
How do I actually uncondemn the house?
Your house will uncondemn itself within 24 hours of your account reactivation. Should it not do so then please open the house sign and select the Ownership tab. On there you will see a button for Make Primary. Selecting this will make this your primary home and stop the decay. Should this button be grayed out you will want to see the next question, "My house won't uncondemn?!" The house status is always listed on the Information page of the house sign.
My house won't uncondemn?!
To find out why lets go down the short list of possibilities. Firstly, is this the only house on the account and/or the most recently gained? If yes then has it been more than 24 hours since you reactivated the account? We generally say 24 as it can take up to 24 hours for all the various involved databases to synchronize. This includes the transaction for your account payment, the account database and the housing database. As long as the house still has 48 more hours before it decays then go ahead and wait 24 hours. Should your house still not uncondemn after 24 hours of account activity then please page a game master. Do this by selecting Help on your paperdoll, then the Other option and Other once more. In your page text be absolutely certain to mention that, "I have reactivated my account more than 24 hours ago and my house will not uncondemn and it is now beyond the slightly worn status!" The exclamation mark is optional of course, but the point is to clearly relay the fact that you have in fact followed the process correctly and now require an intervention. As this is a time sensitive issue please be as clear as possible.

My account is reactivated, yet my house is still condemned?!
i've had houses condemned a few times in the past and activating the account usually worked because by the next day it would be all fine again. but there was one time that it didn't work .. house was still condemned the next day after i activated the account. so i got worried and paged a gm, waited 2 to 3 hours just to receive a canned message telling me to check the support site. from the support site it says wait 24 hours and as long as the house still has 48 more hours before it decays then go ahead and wait 24 hours. i followed that and waited .. after 24 hours of account activation, house still condemned .. waited 24 more hours, IT'S STILL CONDEMNED! so at that point i got really worried .. it's been over 48 hours and house is in greatly worn status and it's still condemned. so i paged gm and i even used the phrase from support site "I have reactivated my account more than 48 hours ago and my house will not uncondemn and it is now beyond the greatly worn status!". waited over 2 hours and received a canned message telling me to check the support site, AGAIN!

my house is gonna fall how does reporting a bug gonna help!? screw the gms, i'm not gonna page and waste hours waiting for some stupid canned message again because it was obvious that either the gms were super lazy and not doing their jobs or they just lack the knowledge of the stuff on the support site .. cause i followed all the steps and used the exact phrase from the support site to clearly relay the fact that i have in fact followed the process correctly and now require an intervention. and they failed to see it.
at the end i moved stuff out of the falling house and the house fell. wasted $ to activate the account for nothing and wasted hours of waiting for stupid canned messages, only to get pissed about it.
floria, if your house is still condemned and it's falling, you may have to do what esmeralda said, find a trustworthy friend and trade the house to prevent it from falling.
