Best concrete driveway pros near Hannibal, MO

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.

The best ways to increase the lifespan of your driveway are to carry out proper maintenance and get repairs done quickly. First, reseal your driveway every one to three years to protect it from the elements. If you start to notice significant cracks, hire a professional to diagnose the problem before it gets more serious. You can also use sand instead of salt when de-icing your driveway (since salt is corrosive) and clean your driveway annually using a pressure washer to keep it in tip-top shape.

You should never use bleach in a pressure washer. While bleach is effective at killing mold and mildew, it is a potent chemical that can corrode the machine's seals and nozzles, destroying it from the inside out. Additionally, pressure washing with bleach sprays the chemical into the air, which is dangerous if inhaled and can kill nearby plants, flowers, or harm animals that ingest it. If you need to remove mold or mildew, it is best to hire a professional who will use a safe and effective cleaning agent.

Maintaining a driveway depends on its material. For concrete and asphalt, it's best to clean the surface thoroughly twice a year with a stiff broom and a pressure washer to remove accumulated dirt and debris. Sealing the driveway is crucial to protect it from water damage and freeze-thaw cycles. Before applying a sealant, pressure wash the surface to remove any loose sealant, dirt, or stains, as sealing over them will trap them. Any cracks or expansion joints should be filled with a flexible polyurethane caulk or asphalt sealer. In colder climates, use sand instead of salt for de-icing. Sand helps melt snow and ice without accelerating the freeze-thaw process, which can cause cracks.
