I have a 70 yr old home in a nice exclusive area in San Antonio, Texas that has some areas that need some work and I am looking for some advice on how to proceed: 1] Both bathrooms have old hexagon shaped floor tiles that are worn. They are obviously placed on some very thick cement base. I would prefer not having to remove the tile as I am sure it would be very expensive. Is there a reliable method of laying tile over tile? 2] The exterior is wood (ship-lap --??spelling) and has gone thru several layers of paint. It is now peeling very badly and in some areas all the way down to the wood. What is a reasonable approach in preparing this home for a new paint job? What should I be looking for when I get bids? I am so afraid to "get taken". How long is it safe to wait to get the job done if it is beginning to peel? I was thinking of waiting until the spring. Is that wise. Is there some good way of finding reliable painters?
