The disadvantages of sandblasting are noise, mess, and risk. Sandblasters are louder than chainsaws and spread debris on the ground and through the air. Let your neighbors know that you're sandblasting so they can prepare. Sandblasting can damage your property if not done properly, so thoroughly vet any pros you talk to before hiring.

Your pro will most likely bill you at an hourly rate of $50 to $80 per hour to sandblast a door due to its small size. This type of job won't take long, so if you have other surfaces that need cleaning, schedule those tasks at the same time to get your money's worth from your pro's visit.

If you’re DIYing the project, it could take up to a week if you aren’t able to dedicate full-time hours. If you hire a professional and they arrive with a team, expect your stairs to be sanded in as little as 2 hours (for simple projects). Finishing the stairs takes a while longer as there are drying and sealing times to consider, but the actual work will take much less time than the sanding portion.

Sandblasting is useful when you need to strip material off a hard surface. Common reasons to sandblast are to remove paint, rust, or get a surface ready for a new material. You aren’t limited to surfaces like walls either—you can sandblast rusted tools, bicycle frames, cement, bricks, and many others. If what you’re sandblasting is still structurally sound, sandblasting can be a fast and inexpensive way to revive the original material.
