If your garage floor is heavily soiled or stained, then it’s a good idea to powerwash it with a concrete cleaner before sealing. This process will remove dirt and debris to help the new sealer bond to the concrete properly, and it will also improve the look of your sealed garage floor. After power washing your floor, make sure you let the concrete dry completely before applying sealant, usually for 24 to 48 hours.

Some homeowners have luck using pressure washers, but this only works for old or weaker concrete sealants and with very powerful pressure washers. You’ll get better results by pressure washing water-based sealants. However, it’s worth trying on any sealant if you’re hoping for the least toxic, least expensive, and most DIY-friendly option. To try this method, rent or buy the most powerful pressure washer you can find and take several passes at the concrete, completely pressure washing the entire area. You may need to repeat the process multiple times to see results.

Pressure washing your home or fence can make a major difference in the appearance and may even help extend the life of the structure you’re cleaning. Some of the most common areas that people pressure wash around their property include:

• Driveway: $100–$250

• Patio: $100–$200

• Fence: $150–$300

• Gutters: $50–$150

• Roof: $450–$700

• Siding: $150–$1,400

• One-story house: $150–$750

• Two-story house: $400–$1,400

• Three-story house: $700–$1,800

Not pressure washing your driveway can lead to several consequences that affect both its appearance and its structural integrity over time:  

• Reduced Curb Appeal: A dirty driveway covered in grime, stains, and mildew detracts from your home's overall appearance.  

• Safety Hazards: The buildup of algae, moss, and mildew creates slippery surfaces. When wet, it increases the risk of slips and falls for you, your family, and visitors.  

• Structural Damage: Dirt, debris, and organic growth can trap moisture against the driveway's surface. In colder climates, this moisture can freeze and thaw, leading to cracks and deterioration of the concrete or asphalt.
