@Neil What is the use of repeating lessons when there is so much more to be learned? Technology has moved on from the adz. Plumbers use PEC, insulation is sprayed, glue-lams allow for open floor plans and furnaces are no longer stoked with coal. As for the new people, if these trades cannot attract fresh blood we will all be unable to get homes built and repairs made. I don't yearn for my first home with the leaky concrete block foundation, failing well pump and an oil furnace held up by the plenum. I'll take heat pumps, solar panels and PVC waste pipes any day.You can get all the sill plate repairs and flitch beams demos you need on YouTube.
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.
Excellent advice because there are many unskilled workers who are "trying to pull the wool over the customers eyes". One has to study about the project for which they are in need. I happen to need dry wall repair and painting done in my home and feel the advice in this article will be a great help to me in hiring someone who is ethical and does good work. Thanks.
