Hi and welcome to PFA,
I’ve replaced the interiors with Airtex Upholstery kits on my Warrior, Seminole and three Seneca’s over the last forty years so I’m pretty good at it, including the carpeting. Here are the items that come to mind at this moment without having thought about it for a while. If I think of other things later I’ll add another email for you. I’m going to guess that your Saratoga and my Seneca are pretty much identical on the inside so we’ll start with that assumption. First, all of the seats have to come out. Next, all of the interior, floor mounted plastic has to be removed. Third, the wall panels. While you can remove the carpet with the wall panels installed, you won’t be able to put in new carpeting without removing them (sorry). Fourth, remove the floor board in the center seat row position. At least on my Seneca, the center seat floor board is made of plywood! Once all of this is removed, vacuum the airplane thoroughly and keep your vacuum cleaner handy. After every piece of carpeting that is removed, vacuum again. Also, do not discard of anything until the project has been completed to your satisfaction. You never know when you’ll need to reference an old piece of carpeting or plastic as the new ones probably won’t fit exactly. As for removing the carpeting, it comes in many pieces, over a dozen come to mind. If the carpeting is really old, it will be dry and so will the glue underneath. Find a centrally located piece of carpeting and grab a corner with a pliers. Slowly and steadily pull up on the pliers and remove the carpeting. Don’t forget, save the carpeting (even mark where it came from and how it was installed with a marker on a piece of masking tape). And don’t forget to vacuum. There are lots of particulate stuff and you don’t want to be breathing it. After all of the carpet is removed and you’ve vacuumed, get a paint scraper and start to remove dried glue. If it won’t come out, get a rubber glue solvent like “Oops” or equipment from your hardware store. Contact me again if you need help.
