Preventative Pressure Washing Tips & Tricks

Going green is the ‘in’ thing nowadays! However, the ‘green’ here refers to being ‘environment friendly’. If you find your house turning green in a literal way because of excessive moss and mildew growth, it is about time that you do something about it! In fact, the best thing to do is to protect your biggest investment, your home, from disrepair as a preventative measure. A great way to ensure that your home remains clean and beautiful; and your curb appeal does not suffer is to undertake some preventative pressure washing.


A pressure washer uses water directed through high pressure nozzles to achieve an effect that would have otherwise taken you hours and hours of hard work and physical exertion. Not only will you be able to get rid of any oil, dirt, and grime stains on the exterior surfaces of your walls, but you will also be able to remove and prevent mold and mildew infestations from proliferating.

Health Concerns

As per the United States Environmental Protection Agency, mold and mildew growth results in a variety of health hazards like asthma, congestion, allergies, wheezing, and poor health overall. You cannot deny the fact that the green growth of mold and mildew detracts from the overall looks and attraction of your home. Preventative pressure washing can ease all these troubles for you.


Tips & Tricks

If you feel out of your depth with the pressure washing machinery, you can easily bid adieu to all this stress and call on professionals listed on outstanding websites or perhaps even a professional you know who does not even have a virtual presence. With only the licensed and best professionals among some of the folks you have shortlisted, you will be making a superb choice irrespective of who you choose. These are a few tips to keep in mind before you take on the preventative pressure washing project.

  1. 1.How much power do you need?

    Consumer pressure washers come in forces of 1,500 to 3,000 pounds per square inch (PSI). If you are considering a small project with light pressure washing, choose one with 1,500 PSI. You will need a stronger one only if you are looking at heavier tasks.

  2. 2.What are you washing?

    If you will be cleaning bricks or wood siding, avoid damage by ensuring that the pressure applied is not too intensive and you do not wash the surface too closely.

  3. 3.Start from the Top

    As common sense dictates, start pressure washing from the top of your home and make your way down. This way all the dirt will flow from top to bottom; and then clear off of your home. If your start the other way around, you will end up blasting debris and dirt from the bottom of your home to the top; and as you clean the top, the bottom will get soiled again! Save your time and energy!

  4. 4.Patio/Porch/Deck

    Many homes boast of a patio, porch, or deck area. If you have one, it will need to be cleaned too. Most of the dirt and debris from the exterior surface of your home will end up on our porch or deck area so clean this place at the very end of our project. Start close to the actual structure of your home and gradually push all the debris away into the yard. When done right, preventative pressure washing will increase the longevity of your deck/porch/patio area by keeping it clean and healthy. If you are confused or just not confident, call on your local pressure washing professionals for help.

  5. 5.Not too Close

    When you are pressure washing your home, the trick to obtain the best results is to angle the hose from about three feet away from the surface. This will help you avoid courting the danger of damaging or cracking any of the surfaces. After pressure washing, wait at least three days before painting your home. Most surfaces will need at least that much drying time.

Prevent & Preserve

Of course, cleaning up existing mold and mildew will give you the pleasure of seeing what the real colors of your walls are like! However, preventative pressure washing will save you plenty of trouble in the long run. Don’t allow mold or mildew to find a long term resting spot in or on your home at all!
