What is the Best Time to Power Wash a House? What pros say


Power washing is a great way to maintain the outdoor areas of your house. It helps get rid of sticky contaminants, dirt, and grime. Homeowners often wonder what the best time to power wash their house is. Power washers use hot water, but still, below-freezing temperatures can damage your house. Power washing in cold weather is just way more tricky and challenging. And when finished, water in the pump and other areas can freeze and damage the pump. In summer, the extreme heat makes the cleaning job more difficult for you, and not all the cleaning chemicals should be used in more extreme conditions.

Generally, power washing your house can be done in most weather conditions. But I do not recommend it when the temperature is below freezing, even when you use hot water for the job.  Weather does not impact the power washing results much due to the hot water. However, the best times to power wash a house are spring and fall. I recommend power washing your house once a year between March and November, except during extreme temperatures.

This article will provide you information about the best time to power wash your house. It will also give you some tips to clean your house with and without a power or pressure washer. And it will give you information about how to power wash in the winter season.

Power washing in spring

Spring is a great time to clean your house and outdoor areas. Snow and rain create a buildup of dirt and grime on the outside of the house. Surfaces like roofs, decks, gutters, and sidings are more prone to mold and mildew in winter. Mold sits on these surfaces and damages them. Power washing the house soon after winter helps you get rid of the mold and mildew and cleans and protects the outdoor surfaces effectively.

Power washing in fall

The less delicate outside areas of the house can handle the dirt brought by winter until fall. Driveways, sidewalks, patios, porches, and other stone or concrete surfaces can be cleaned in the fall when it’s not so hot outside. Power washing concrete and stone surfaces can make them last longer. You can also wait to clean these areas until fall because outdoor summer activities can leave stains and sticky contaminants. Power washing these contaminants before winter is a good way to keep the outdoor surfaces clean and ready for the new season.

Should I power wash my house in the fall?

It is fine to power wash your house at the end fall. During fall, leaves can build up in your gutters, and wind can blow the leaves and debris into hard-to-reach areas. In addition, the dust and pollen can freeze and be caked on during the winter if not removed in time. The buildup becomes a greater challenge to remove once winter is over. Power washing your house before the winter kicks in is a good idea.

Leaves left on different surfaces trap moisture and promote mold and fungus once they get covered with snow in winter. Power washing in the fall helps prevent this and removes sticky residue and other similar materials stuck on outdoor surfaces like patios and decks due to summer activities. I always recommend removing dust and pollen from windows, wash decks, and clear gutters before the cold season starts and snow will fall. Power washing your house in the fall is an excellent way to winterize them.

Is it safe to pressure wash your house?

It is absolutely safe to power wash or pressure wash your house as long as you use a safe PSI rating for cleaning the different surfaces. Use a lower PSI setting to clean surfaces like decks, vinyl sidings, and areas using softer wood. And a higher pressure for cleaning driveways and concrete. When done incorrectly, pressure washing can cause serious damage to your house.

There are many benefits to pressure washing your house. A pressure washer helps you to clean dirt, stains, mold, mildew, and other contaminants from outdoor surfaces of your house when used properly. Despite all of these benefits, a pressure washer can cause great damage when used incorrectly. It can damage sidings, blast away the mortar from brick walls, break windows, or cause the window seals to leak. Pressure washing at very high pressure can even remove paint from the walls.

For safe and effective cleaning, adjust the pressure of the washer according to the surface you are cleaning. For example, concrete is a rigid material and withstands pressure up to 3000 PSI, but decks require very low-pressure settings (i.e., 500-600 PSI) for safe and effective cleaning.

I also recommend being extremely careful when cleaning during freezing temperatures. When using a power washer or pressure washer, water will enter many places it usually can not reach. When this water freezes, it will expand. This expansion can cause significant damage to many areas or surfaces.

How can I clean my house without a pressure washer? Some helpful tips

You can clean your house without a pressure washer by increasing the water pressure coming from your hose. If your mains pressure is fine, you can use a hose extension. This extension will use a nozzle that increases the normal water pressure to a higher one. This is enough for light-duty cleaning jobs, like cleaning your car, sidings, patios, or windows. For tough stains, this will not be enough. A power washer or pressure washer is a better option.

There are several options to increase the pressure of your hose:

● Step 1: Inspect the hose

The first step is to check the hose. Hose adapters can increase the pressure of your hose but will not produce as much pressure as a real pressure washer. Pressure washers have a built-in pump that produces 500 PSI or more. Hose adapters, like a firefighter-type nozzle, can increase the pressure up to 250 psi. It will depend on the amount of water that your faucet can deliver. The more water, the higher the output pressure.

Check the hose and connection to the faucet, and ensure that it does not leak.

● Step 2: Install the high-pressure nozzle

High-pressure nozzles are readily available at hardware stores or online. These nozzles can be installed easily onto the hose without any specialized tools or equipment. These nozzles come with a long, thin tube and concentrate the water to increase the pressure. For cleaning different surfaces, you can adjust the nozzle to change the settings. Similar to a pressure washer nozzle, adjustments for water flow and the shape of the spray can be made.

Different types of nozzles can be used to increase the pressure of your hose:

– Turbo Jet Power washer:

A turbojet power washer is an excellent attachment that can convert any hose into a pressure washer. It has a built-in pressure chamber. It converts the normal water flow of the house into a powerful jet stream that helps you to remove dirt, grime, and mold. It can be used to clean wood, aluminum, concrete, bricks, vinyl sidings, and many other surfaces.

– Little Big Shot Super Nozzle:

This is one of the best high-pressure nozzles because of its small size. It produces 40% more pressure with 40% less water usage.

– Firefighter-style nozzles:

The firefighter-style nozzles are a good choice for cleaning. With a thick hose that delivers enough gallons per minute, they produce up to 250 PSI water pressure. With a smaller hose or less water pressure, the output pressure will be lower.

– Wand-style nozzles:

Wand-style nozzles effectively increase the pressure of the water coming through the hose. They are a fine choice for cleaning upper story windows, sidings, patios, and outdoor furniture.

– Squeeze-handle nozzles:

These nozzles produce water pressure up to 150 PSI. They can be used to clean dirt and mold buildup.

Find the perfect amount of water flow by opening the water flow lever slowly. To clean surfaces like concrete, adjust the nozzle spray to a pinpoint or compact fan shape. To prevent delicate surfaces like windows or vinyl sidings from cracking, make sure the spray is wider while cleaning these surfaces.

● Step 3: Use a thick hose and short hose

To achieve high water pressure, use a thick hose. And use a short hose length. The thicker the hose is, the more water can be sent to the nozzle. A long hose means that water travels a longer distance, which reduces the pressure of the water. Therefore, always make sure that you use a thick hose with a minimum length so that the amount of water and the pressure is as high as possible. And no energy is lost due to the bends or twists of the hose.

● Step 4: Install an additional water pump

Another way to increase the water pressure for effective cleaning without a pressure washer is to use a water pump. This will increase the pressure of your main water supply. If you live in an area with lower water pressure, this can give a nice boost. Together with a good nozzle, this can give a nice increase in the pressure coming from your hose. A water pump connects to an outlet, and a hose is attached to the pump to get a stronger stream.

The pump increases the outside pressure significantly and allows you to achieve adequate pressure for cleaning outdoors and other purposes. Often a water pump comes with a water pressure regulator that allows you to regulate the pressure according to your choice. There are many types of pumps available on the market which are used for different purposes. For increasing the water pressure outside, a more cost-effective regular water pump will do the job fine.

How warm does it need to be to power wash a house?

I recommend only power wash, or pressure wash a house when the temperature is above 32 degrees Fahrenheit during the night. When lower, the water will freeze. When using a power washer or pressure washer, water will reach areas normal rain will not reach. With colder temperatures, it will take longer to evaporate. And when the water freezes, it will expand and can do significant damage.

Additionally, power washing your house at a temperature below the freezing point can damage your washer as well when cooled down. Most experts do not recommend power washing once the temperature falls below 40 degrees.

Should you power wash a house in winter?

Power washing can be done in winter, but it is not recommended for beginners. During the winter season, power washing becomes much more challenging. When you use hot pressurized water, it will find its way in all cracks and locations normal rain will not reach. With a temperature below freezing, the water will freeze and expand and can do significant damage.

Also, the power washer itself can get damaged. The pipes and other components inside the pressure washer may freeze if you fail to drain the water lines properly. Store the equipment in a warmer area.

Generally, power washing below 40 degrees is not recommended. Even do a power washer uses hot water, it will cool down quickly. And chemicals become less effective in colder temperatures.

Professional power washing companies use different techniques to wash the houses effectively during winter. Here are some of the tips that you can follow to power wash your house in winter without causing any problems.

● De-icing:

If you are power washing outside in freezing temperatures, use some rock salt or sand to prevent icing across the sidewalk or driveway. Magnesium and calcium chloride can also be used.

● Perform the cleaning job in the afternoon:

For most people, it is tempting to do the cleaning job in the morning. However, it is better to wait for the afternoon during cold days before starting to power wash your house. In the afternoon, the sun’s heat warms up most surfaces and helps with the drying process.

● Do not power wash the deck in winters:

The recommended temperature for power washing a deck is 52 degrees Fahrenheit. If you power wash or pressure wash the deck in colder temperatures, it will not really dry completely. This makes it easier for moisture to get trapped in the wood and build up mildew.

● Access to indoor faucets:

In many areas in the United States, you need to take care of faucets during the winter not to freeze. If you want to power wash or pressure wash, you need to have a working faucet available or use an indoor one.

● Chemical imbalance:

Most of the cleaning chemicals used in power washing the house do not work effectively in colder temperatures. Even do a power washer uses hot water, it will cool down quickly. Also, most tough stains are even harder to clean when it is cold. The key ingredient involved in the cleaning chemical reaction is heated. In colder conditions, you must use extra chemicals to ensure effective cleaning of the surfaces.

● Store the power washer in a warm place:

If the temperature gets below freezing, the frozen water inside the pump expands and will damage the pump. To protect the water lines and fittings in the pressure washer, store your pressure washer in a dry and warm place.
