My paint projects always include sanding, caulking, spackling, and all prep work to ensure a good adherence. Prep work is what makes the paint job last. I absolutely respect your furniture and outside bushes. Drop cloths are used whenever possible outside and always inside. Trenching at foundation 4 to 6 inches Masking of all shrubbery, walkways, pools, etc.
Painting is the number one thing a person can do to improve the look of their home.
It is also very important for the preservation of your home. A home that has been properly prepped, then sealed with quality paint will be protected from the elements. A poorly painted house is like a leaky roof. Once it starts letting water in, the damage can be severe. There are lots of good painters, but not many who take the time to prep a home properly.
