Hi! I live in Puerto Rico, here the houses are made of concrete. I have to replace all five doors of my house because I found termites in the frames. I went window shopping for frames but I found that the frames I liked were 8 feet high. Three of the frames I need are 8'11'' high. What should I do? Can I do the proyect with my husband or should I contract someone who knows? If I can do the proyect, I have to fix the cement wall after terring the frames and before putting the new ones? If you have a videotape refering to this proyect, please send how can I get it.
