ainting Professionals We were quite impressed with how thorough greenwave painting solutions was when they painted our house. They did a lot of prep work. They even took a knife and cut out and removed the old caulk on our house. The last painters we used just caulked on top of the old caulk. They also scraped off that old stuff on the window grids and put new window stuff around the panes. I don't know what its called, but makes our windows more air tight. Our air conditioning bill was cheaper because our house is more air tight. What a great little extra bonus. Greenwave solutions is a really awesome painting contractor.
