Nope! Please leave the old tack strips in place. We should be able to reuse them. If there are any that are in bad shape we will pull them up and replace them when we arrive.
You do, however, need to remove all the staples left over from the old padding. To remove staples, you may choose to pull them using needle nose or lineman's pliers, or a quicker way is to use a flat garden hoe to scrape across the floor surface from a standing position. Be cautious with this method if you wish to preserve a finished hardwood flooring under the carpet.
