Great question! Unfortunately, the answer is not very simple, as cost is affected by many factors. Often people want a quick square footage price and that is only one piece of the puzzle when it comes to most installations. A glue down Vinyl Plank install is priced differently than a click install. Installing Vinyl Plank on stairs is more costly than installing it on your floor. Any additional work required is very job specific and makes up the entire scope of work for an installation project. Removal and replacement of doors and furniture, finishing around railings, moving appliance etc. are all very common tasks that make up a typical flooring installation. Also, the condition of your subfloor is the biggest wild card when it comes to determining the cost of an installation. Some subfloors require repairs to ensure the floor can be installed to meet the manufactures expectations. A thorough estimation process is required to provide an accurate installation cost for each project.
