Pressure washing vs soft-washing!

Spring is right around the corner and you have a list a mile long of what needs to get done. Once those temperatures rise it’s time to emerge from our winter hibernation and we get the first glimpse of the sunshine filled outside world. Unfortunately, the first thing we see may not be all that pleasing to the eye.

We begin to see the ugly emergence of that all too familiar friend, MOLD. Mold on our siding, mold on our brick, mold just about everywhere. During the winter months, the cold weather doesn’t kill mold spores. They survive just as other plants do, hiding in the pores of your exterior surfaces, and as the weather warms they go into growth mode. Taking in all the fresh moisture they can grow, making our homes an ugly green rather than a fresh clean.

So now it’s time to have your home cleaned and you need to decide if you are going to do it yourself or hire a professional. Most homeowners think homes can be pressure washed and that’s all they need. This idea is outdated and has been given to them by home improvement stores, painters, general contractors and even some window cleaning companies. So they rent a pressure washer, use their own or hire one of these general guys with a power washer to clean their siding or roof.

 

This is where the trouble starts… What you won’t see is what’s actually happening. First, yes the mold is being pushed off the surface, but only the surface mold. The source of the mold, where it actually grows from, is still deep in the pores of the surface. More than likely your surface now has damage from the pressure which only provides the mold spores more areas to hide in. Next year, or even later the same year prepare for even more mold to show up!

Vinyl siding and even aluminum siding was never meant to be pressure washed. Vinyl siding has a clear coat cover the outer most layer consisting of protective materials including a UV protective coating which prevents your siding from fading in the sun.

Over time this outer coating oxidizes and begins to look cloudy. This can be seen very commonly near water spigots on the side of the home where you might lean against the siding, leaving an absence of oxidation where your fingers may have rubbed it off.

High pressure used on these surfaces can pre-maturely remove these coatings causing damage, early sun damage, degradation and even in some cases voiding a warranty. A leading high-end siding manufacturer, CertainTeed, warns consumers away from pressure washing siding “NOTE:  We do not recommend power washing vinyl or polymer siding as it can cause moisture intrusion, damage, and/or discoloration.” and instead recommend using the SOFT WASH method.

When using hard pressure this oxidation can be easily removed leaving visible streaks that actually make your home look cleaner but in reality, it removed all of your UV protective coatings, exposing your home to the damaging effects of the sun.

Once this oxidation is removed by an untrained professional or homeowner, it will be streaky and very unsightly. The only cleaning option at this point is a full chemical restoration and unfortunately, this can be very expensive.

This is why we recommend not remove this oxidation in the first place. DON’T USE PRESSURE!

SOFT WASHING is the new industry standard. Quite simply it’s washing a surface, vinyl, aluminum, soft stone, even brick with a gentle rinse. Using chemicals, specially designed to kill the mold spores and used in a manner that is safe for your existing landscaping, pets, and the environment. This gentle rinse washes the dead mold away leaving your surface completely clean all the way into the pores.

You may ask why companies like Powergreen Pressure Washing use pressure washers if they use the SOFT WASH method. Pressure is still used on concrete combines with heat and chemicals to clean years of mold and abuse on most hard surfaces. We then use special pumps designed for distance and volume rather than pressure to clean your vertical soft surfaces, chemically injecting our solution to the hardest to reach places. Soft bristle brushes can also be used to remove the most stubborn old stains and growth.

No other method is recommended for cleaning siding and if another contractor or professional tells you otherwise, be cautious as they most likely don’t have your best interest in mind.

 

Pressure should ONLY be used on hard surfaces such as concrete, hard stone, and some brick. Surfaces such as vinyl, aluminum, stucco, soft stone, and wood should ONLY be treated with a “soft-wash”
