How Do You Know When To Pressure Wash Your Brick House?

Brick houses are beautiful, but they can have a lot of dirt, grime, mold, and mildew on them. As a property owner, it is your duty to keep a check on your home’s walls and bricks. The dirt and mildew slowly damage your walls without letting you know.

This is often the case when you live in an area that has a lot of trees or plants around your house. While constant dirt and dust accumulation is another major cause of damage to your brick home.

For example, a property owner in New Orleans may want to use a quality pressure washer more often. It helps to keep his bricks clean and beautiful while living in New Orleans for years (or decades) because he lives in an area with lots of moss and mold.

However, people living in the cities may need power washing their brick homes less often. But they should clean their brick walls using a pressure washer at least every year to seure their home from mold and mildew.

It’s important to understand the benefits of pressure washing a brick house so that you can decide whether or not it is worth the investment. In this blog post, we will discuss how to properly pressure wash a brick house as well as how it can help with other problems that may arise on your property.

Important Steps and Precautions For Washing Your Brick Walls With a Pressure Washer

When it comes to how do you powerwash bricks, there are several steps that should be taken in order to safely clean the exterior of your home. If done improperly, pressure washing can cause damage and permanently discolor your home. Here’s how to pressure wash a brick house:

Need A Good Pressure Washer For Heavy Task Of Washing Your Brick Home 

  • The first thing you need to do is find a pressure washer that has enough power to clean the brick.
  • You can use a good gas pressure washer for power washing your home walls but at the same time, a precise and quality electric power washer like Sunjoe SPX 3000 can also do this task with great efficiency.
  • PSI is a crucial factor when it comes to choosing a pressure washer for brick washing and cleaning. Right here, people often do something wrong. It’s possible that you will damage your brick walls if you use a high PSI pressure washer like 4000PSI or more.
  • Therefore experts recommend a pressure washer with a PSI ranging between 2000 and 3200 PSI. If you possess an electric pressure washer for deck cleaning, you can easily use it. In any case, avoid exceeding 3200 PSI when using different pressure washers.

Some Precautions You Must Follow Before Washing Brick Walls And Sidings

  • Clean up any loose debris on the ground and around the house. Make sure the area where you will be working is safe and free of debris.
  • Ensure that there are no people or animals nearby when you’re washing your house as they may get hurt by the high water pressure.
  • Make sure you stay safe while pressure washing a brick house! Always wear long pants, closed-toed shoes, and any other protective gear that you may need in order to prevent injury from the dirt or debris on your home. Gloves are usually recommended as well for added protection against sharp objects.
  • Always keep an eye out for any cracks in the surface of your bricks – if it’s too deep, don’t continue cleaning those areas until they’ve been repaired.

Prepare Your Brick Walls For Excellent Pressure Washing Results

The preparation of the brick walls prior to pressure washing is extremely important. Why? Because it is not a good idea to let water penetrate into its inner surface. The wall can suffer huge damage if this happens.

  • Brick mortar is prone to damage over time. Before starting, you must inspect the bricks for missing mortar. If there is something wrong, fill the spaces between the bricks with new mortar. Now, wait for 5 to 6 days before pressure washing your walls and sidings. This way, you will have better washing results.
  • Soaking your brick home before you clean it is important. This is great to prepare the surface for cleaning so there won’t be any issues with streaking when applied to a wet or damp area of the house.

Its Time To Pressure Wash Your Brick Walls And Exterior Of Your Home

  • When spraying your house, start from the bottom going upwards. This way you can ensure an even application of water that will not run down unevenly and not cause streaking.
  • When using your pressure washer on bricks, use a low-pressure setting and work in small sections at a time.
  • If your bricks have never been cleaned before, start with a high water temperature so dirt can come off more easily without damaging them. Moreover, this may clean your walls without using any chemicals.
  • Spray down all surfaces of the brick until they are clean. If you are not satisfied, apply a soap solution recommended for pressure washing to remove dirt, mold, algae, lichens, and other substances that can be harmful to your home’s exterior.
  • Start applying soap from the top and work down.
  • Use a scrub brush to clean areas that are caked with dirt or loose paint. This is an additional option to get better results.
  • Rinse off any remaining cleaner or residue from bricks using an additional rinse cycle for safety purposes. Move-in circular motions while spraying off as you go. Work your way around until all sides of the house have been cleaned.
  • Wait for it to dry completely before applying another coat of soap if necessary.
  • Inspect each surface of your home before you leave so that you know it is safe for entry into your home again.


How deep does the water need to penetrate while washing a brick wall or brick house?

It depends on how dirty the brick is. If it’s just a little dirty, the water will be able to penetrate deep enough. If there is mold and mildew growing on your brick, you’ll have to hold down the trigger for long periods of time so that the high-pressure stream can kill all of the bacteria in those areas.

How much does pressure washing a brick house cost?

The price of pressure washing a brick house will vary depending on how many square feet you need to clean. For example, if there is only mildew and algae growing in two small areas (less than 100 sq ft), it shouldn’t cost more than $150-$250 for an experienced contractor with a gas-powered machine to complete the job.

Do you have to be in the water while pressure washing brick?

No, it is not safe. The high-powered stream could seriously hurt a person if they accidentally get too close. Pressure washers will also send small rocks flying through the air which can damage the property and cause injury to people.

How often should I pressure wash my brick walls or brick home?

It will depend on how much dirt, grime, mildew, or mold is growing in your area. For example, if you live near trees that have moss, it’s important to power wash once every three months. If there is only dirt or mud accumulating on your brick, you should pressure wash after every six months.


If you want a clean exterior, follow the steps we’ve laid out above for pressure washing your brick house walls. We recommend using an electric pressure washer with cold water following the above safety precautions to avoid any scratches or damage to your brick walls.
