Filling gaps with a paintable acrylic-latex caulk cuts down on drafts and makes your trim look better than new. The secret to using caulk is to cut the tip smaller than you think it should be; too much caulk makes a mess. Also, instead of using a nail to break the inner seal, use a small wire so you don't stretch out the nozzle. Also consider buying a dripless caulk gun, which will automatically back off the pressure after each pull on the trigger to prevent unwanted oozing.
These guys are first class. We are going to be building soon, and I will be using this company to do all interior and exterior paint. Heidi and Warren are fully involved from the start to the finish of the project and they are exceptionally helpful. These guys are all wonderful. They show up when they say they are going to show up. They are respectful on the worksite and everyone is friendly and hardworking. Thanks guys. Looking forward to working with you again soon!
Not all people live where they can hire a painting contractor, like you describe. People who live in small towns can only hire painters who have a very small business, and do two or three paint jobs per week. In this case, you do have to be very careful, when you hire a painter, as we have several, in our area, who are out to make a fast buck anyway they can.
