Since Farmer's Insurance so inconsiderately dumped their customers in Texas, even those of us that have been with them for over 20 years, I had to find another insurance company. And with mold claims everywhere, the insurance companies are very wary of insuring anything right now.
I checked some newer homes in the Austin area where I live and noticed that they have about 1/2 inch diameter weep holes every 3 to 4 feet.
Allstate Insurance apparently requires that weep holes are present. They sent out an inspector since I am a new client with them, and the house failed due to the absence of the weep holes.
The rock exterior meets the foundation, which is at least 6 inches above ground level around the entire house.
No other house in this neighborhood that has a stone exterior has weep holes, and the homes average 20 years or so in age.
It is not a big deal for me to go ahead and put them in, but another concern is that the holes will basically open the house to every bug within a mile radius. I have seen screens that can be installed for weep holes in brick, but nothing similar for stone.
With the tight insurance market in Texas, I don't really have much choice except to put them in.
The good news is that Allstate offers car insurance much lower than Farmers. The savings of over $800 per year makes them worth staying with.
