Q: Can I pressure wash my own deck?

• <div><p>It is possible to <a href="https://www.angi.com/articles/how-to-power-wash-deck.htm">pressure wash your deck</a>, but it&rsquo;s usually best to leave the work to a professional for two main reasons. First, power washers are expensive, and you can avoid high upfront costs by hiring a deck washing pro instead. Second, you must be careful to use the correct setting to avoid damaging your deck material. You can only clean soft woods like pine with a wide spray and a low pressure; otherwise, the water will leave unpleasant marks on your deck. Hard woods, composite material, and metal can stand up to increasingly higher water pressures.</p></div>

Question 1

What is the best PSI to pressure wash a driveway?

Accepted Answer

•

For pressure washing a driveway, a PSI (pounds per square inch) between 2,000 and 3,000 is recommended for both concrete and asphalt surfaces. A pressure of 3,000 PSI is ideal for deep cleaning without causing damage, effectively removing debris, dirt stains, and even oil spills. If your pressure washer has a lower PSI rating, you can still use it, but the cleaning process will take longer. For a more efficient and even clean, consider using a surface cleaner attachment.

Question 3

Should I use bleach in a pressure washer?

Accepted Answer

•

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.

Question 4

What should I consider or ask when hiring a professional pressure washing service?

Accepted Answer

•

When hiring a professional to pressure wash your home, it's crucial to choose a company that is bonded, licensed, and insured. This protects you from liability if any accidents or property damage occur during the service; otherwise, the cost could fall on you. Before making a decision, vet at least three different contractors. Conduct thorough research by reading customer reviews, looking at examples of their previous work, and verifying the company's license. Before signing a contract, ensure you receive a written estimate that details all project costs. It's also wise to ask potential contractors a series of questions to gauge their professionalism and experience, such as:

How many years of experience do you have?
What are your credentials?
What cleaning methods do you use?
Do you have a workmanship warranty and insurance?
What is your availability?
What is your policy if you damage my property?
How long will the job take to complete?
How much do you charge?
What is your cancellation policy?
Do you offer a customer satisfaction guarantee or any additional services?

Question 5

Is it a good idea to pressure wash a wood deck?

Accepted Answer

•

Yes, pressure washing a wood deck can be a good idea as it effectively lifts ingrained dirt, mold, and mildew, improving the deck's appearance and longevity. However, it must be done carefully, as it's easy to damage the wood, especially softwoods. To pressure wash safely, use a lower pressure setting and a wide, 40-degree fan pattern nozzle (often white). Keep the nozzle at least a foot away from the wood surface and maintain constant motion, avoiding hovering in one spot to prevent gouging.
