Hello everyone, I have some rot on a few fascia boards which I am going to try to replace myself. I am not certain what type of 'wood' or board to get at the big box store. I know I want something that's been treated and 1"x8" 8. Do I just ask for that size board or do I look for a specific board for this application? Would this be what I need to get: [url]https://www.homedepot.com/p/WeatherShield-1-in-x-8-in-x-8-ft-Ground-Contact-Pressure-Treated-Board-253936/206974327[/url] I am also thinking about wood deck screws instead of nails, thoughts? Thanks!

Hi, I'm trying to install 6 in. wall vent for gas range hood vent on existing siding. I did some research and best way it seems to be cut out the siding (size of the wall vent cap), install the vent cap and install J-channel around the edge of the vent cap. To install J-channel, it requires to be nailed to the wall. However, in order to do this looks like I have to remove the existing siding to nail the J-channel. In fear of messing up the siding, I just want to put silicone caulk as an adhesive to hold the J-channel in place. I asked around people from home depot, lowes, and some of the contractors and I'm getting mixed answers. Some says it shouldn't be a problem and some say J-channel will warp. Is it okay to hold J-channel using caulk or do I have to nail it on the wall? Thanks in advance
