Every home has a side or face that doesn’t get any sun, so mold and mildew are likely something you’ll have to deal with at some point or another. Home improvement stores advertise bleach washes to kill the mold and mildew at the source, but undiluted harsh chemicals can damage the home’s finish and kill nearby plant life. Pressure washing blows the mold and mildew out of the texture of the siding, and if the contractor adds bleach solution to the wash mixture, it can safely reduce the likelihood of immediate regrowth. Solutions that promise to prevent growth do so by leaving a film of chemical on the siding, which isn’t healthy for the finish. Windows and doors are particularly vulnerable areas when pressure washing a structure.

With DIY pressure washing, you can save money and get familiar with your house’s nooks and crannies.

There is little as satisfying as having your home looking clean and new. Having your house pressure washed is simple with professionals.

In essence, preparing your house for pressure washing is about safeguarding both your property and the environment around it. In this guide, we’ll cover the steps to get your house looking its best. From preparing your home and setting up the washer, to the actual washing and post-care. We’ll answer common questions and offer tips to ensure a successful clean.

Pressure washing a house tends to take anywhere from 30 minutes to several hours. It may also take an additional 15 to 30 minutes of setup time and pack time, and some time may be required to switch between applying the cleaning chemicals and rinsing them off. Roofers know how to spot problems (leaks, missing shingles, moss or mold growth, etc.)  in your roof that could potentially save you from costly repairs down the road. But homeowners living near a busy road, with lots of surrounding trees, or where it’s generally dusty, stormy, and windy might need to do it in the spring and fall. The best time to pressure wash a house is between March and November.

It’s similar to sanding down a piece of furniture before repainting it. Pressure washers look like the ultimate squirt gun, but they aren’t toys. Don’t point them at anyone or try to rinse your hands or feet.

Now that your pressure washer is all set up, it’s time to get down to the actual washing. Pressure washing your house can be satisfying, especially when you see the dirt wash away, leaving your home looking fresh and clean. In short, yes, you should pressure wash a house before painting it. Even if the exterior appears to be clean, it is almost certainly quite dirty, and paint will not adhere well to a dirty surface. What’s more, if you don’t wash the house first, you’ll trap all kinds of built-up grime and dirt in the paint, and your expensive, time-consuming paint job won’t look good.
