Best concrete driveway pros near Union, IL

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.

You should always power wash your driveway before applying a sealant. At any given time, your driveway could be covered with algae and moss, tire residue, oil and rust stains, and any combination of leaves, twigs, and dirt. If you skip power washing, you’ll be trapping the dirt and grime beneath the sealant and lowering its chance of cementing itself to your driveway. While you can expect the cost to pressure wash your driveway to average between $100 and $350, the few hundred dollars beats an unattractive driveway or paying extra to reapply your driveway sealer.

The average cost to pressure wash a house is around $310, with typical prices ranging from $200 to $420. However, the total cost can vary widely, from $200 to $750. Power washing, which uses heated water, may cost between $250 and $400 per project, with an average of $200 to $300 for a 2,000-square-foot home.

Key factors that influence the final price include:

• The size and height of the house (a multi-level home costs more than a single-story one).

• The complexity of the job and accessibility of certain areas.

• Geographic location.

• Equipment and hourly labor costs.

Hiring a professional is often recommended as they bring their own equipment and cleaning solutions. Experienced professionals know how to complete the job effectively without causing damage to your siding, gutters, or landscaping, which can be a risk with high-powered water jets.

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.
