Sanding and refinishing your floor is a big job and one that creates a lot of dust. If you are considering doing this yourself, you may want to consider renting a dustless sander. This type of sander uses a vacuum system to collect the dust as you sand, making the job much easier and cleaner. If you are hiring a professional to do the job, make sure to ask if they use a dustless sander. Many companies now offer this service, and it can make a big difference in the amount of cleanup required afterward.
