DIY floor sanding is risky and rarely produces professional results. Drum sanders are powerful machines that can gouge or damage your floors if not handled properly. Even small mistakes can require expensive repairs or complete board replacement.
The process requires specific knowledge about grit sequences, sanding patterns, and how different wood types respond to sanding. Inexperienced operators often create waves, gouges, or uneven surfaces that are costly to fix. Equipment rental, sandpaper, stains, and finishes add up quickly too.
Professional sanding includes proper equipment, experience with different wood types, dust containment, and warranty protection. When you factor in the time, physical effort, potential mistakes, and equipment costs, professional service usually costs less while delivering guaranteed results. Your floors are too valuable to risk on a learning experience.
