A lot of homeowners don’t know everything about what exterior house washing companies do, so when we get asked, “Can pressure washing damage your house?” We answer them with, “Well, there’s a possibility, if not done properly.” In a nutshell, you should take extra safety precautions and avoid improper pressure washing when doing the procedure as much as possible. Or else, you might mess up and cause irreversible damage to your home. We’re not here to scare you. House Washing Experts know how important it is to make things right. So, let’s expound on the most common damages that improper pressure washing does.

Water Buildup

It’s true that pressure washing can remove stains, dirt, debris and other contaminants on your home’s surfaces, while also preventing them from accumulating. But here’s the tricky part: there are times that a pressure washer is set and used into the highest settings that it just blasts off too much pressure on your home’s siding, wall, concrete and other surfaces. And when these surfaces are situated in shaded areas, they get moist instead of being completely dry. This is what water buildup can do. In return, you have to deal with mould and mildew growth again.

Improper pressure washing can cost you more. Instead of doing the process in one go, you might see yourself seeking assistance to another from another external house washing company to wash away the accumulated contaminants. And of course, this is something that not all homeowners have the time to deal with.

Removed or Dented Parts

High-pressure washing does not apply to all parts of your home’s exterior. That’s one thing to keep in mind. So if you’ve just rented or bought a pressure washer and it’s your first time to use it, we highly suggest that you leave it to the experts. Or else, parts of your siding or roof might be accidentally removed. Improper pressure washing can also cause dents, which are unsightly in the first place. You surely don’t want to leave your home with more imperfections.

Removed or Discoloured Paint

This is highly common among old homes. High-pressure washing, when done incorrectly, can remove or chip off paint. You’ll see some minor dents that can become noticeable once you look closely. In some cases, paint gets discoloured, too. The culprit? Blasting off high-pressure water in the paint.

Here’s one thing to keep in mind. You can start at a low setting when using your pressure washer, and if you see that the dirt, debris and mould are washing off, keep the pressure at that level. You don’t necessarily have to put the machine at its highest setting right off the bat. Paint with coat finishes are less likely to break up, but it’s best not to become so sure of it.

The right exterior house washing company know what’s the right amount of pressure to use. If you’re sceptical about using a pressure washer, simply work with the experts and let them take care of it.

Hard Surfaces with Splinters and Cracks

Wood and stone can be prime examples. Improper pressure washing, especially with high-pressure water, can weaken the foundation of your walls, floor, and hard-to-reach areas, causing them to splinter and crack. Not only they are total eyesores, but can also puncture someone’s skin.

Pressure Washing: The Right Way

Forget about improper pressure washing and instead, focus on these three things: the amount of pressure, distance and technique.

Amount of Pressure

High pressure isn’t good and effective all the time. The higher the amount of pressure, the higher the risk of damage.

Surfaces on your driveway and patio can handle this. But on walls, fences, and even your roof, you should be extra careful. Experts suggest that you opt for soft washing with low-water pressure.

A thought to keep in mind is that pressure washing is no easy task. It’s not as simple as using a pressure washer anywhere you want. It’s really important that you know what you’re washing, what it’s made of, and the appropriate setting to use.


No matter how tempting it is, don’t blast the water close to the surface. Plus, it will even get worse with high-pressure. You can get rid of any dirt, but you’ll also cause dents, scratches, and discolouration of the surface. That’s not good at all.


Improper pressure washing is often a result of lack of skills and experience. So again, if you’ve no idea how it works, you don’t have to force yourself to DIY. You might be gripping your pressure washer the wrong way, pointing at a bad angle, and blasting water three inches from the surface. Of course, it’s no good.

It’s not that complicated, but it needs knowledge and more practice before you get a seamless, fantastic result. And who are the people who have the characteristics? You can find them in a local house washing company.
