Help! The house my daughter is buying has two holes in the siding because the owner put dog houses up against the house with a hole accessable for the dogs to enter and exit. The dog houses are still there; one hole which was in the dining area has been patched inside; the second hole is in an extra room which was used mostly for the dogs. How can these holes be fixed quickly without spending a lot of money? We would feel more secure with the holes patched as soon as we move in.
