Tips for high-quality paint job

Task trickier when mildew is present

Q: I’ve been putting off painting my house for years. It should have been done five years ago, but with one thing or another, it just didn’t happen. I guess now I’m going to pay the price.

My house has a combination of stucco and wood siding. When I rub my hand on the wood and the stucco, I get a chalky residue. There are areas on the shady side of my house that have brown spots and other areas of the wood trim that are blistering. I’m going to do this job myself to save some money. Could you give me some pointers on how I can do a good job so I won’t have to redo it anytime soon?
