Cracking is one of the most common paint problems in Northern Virginia. Builders use inexpensive and low quality  caulking when painting your house. As the temperatures change, your house expands and contracts. As this  happens over and over again, the caulking doesn’t hold up and begins to break down and crack leaving your  home exposed. Moisture can get into these cracks and goes back behind your boards. This leads to boards  warping away from the house, or boards rotting from the inside out. In order to properly protect your home,  we recommend resealing all of these cracks with a siliconized acrylic caulking. Silicone is more flexible than  standard contractors caulking, so it will breathe with the house and last longer. However, paint will not stick to silicone caulking. This is why we recommend siliconized acrylic caulking that will hold paint, but also last longer
