Most contractors charge between $0.30 to $0.40 per square foot to pressure wash siding. Before a contractor agrees to clean your home’s siding, the company will want to know the total area size. Square footage calculations are used to determine how many labor hours will be needed and how much cleaning agent will be needed for the job. You’ll need the total height and width in feet outside of your home to start. Then, multiply the two figures to get the total square footage for siding cleaning estimates. The following are the average costs per square foot to clean homes with vinyl siding.
| Home Size | Siding Size | Cost To Clean Siding |
|---|
| 500 sq.ft. | 1,000 sq.ft. | $300-$400 |
| 1,000 sq.ft. | 1,500 sq.ft. | $450-$600 |
| 1,500 sq.ft. | 2,500 sq.ft. | $750-$1,000 |
| 2,200 sq.ft. | 3,000 sq.ft. | $900-$1,200 |
| 2,500 sq.ft. | 3,500 sq.ft. | $1,050-$1,400 |
Siding Cleaning Cost by Method
Depending on the method, you’ll spend anywhere from $0.25 to $0.55 per square foot to clean siding. The contractor evaluates the exterior of the home to determine the best method to remove dirt and mold. Pressure wash companies specialize in cleaning mold, dirt, and other debris from siding. However, if a deep cleaning is needed, the contractor may consider other methods like power washing. The following costs reflect the average you’ll pay per method based on square footage and hourly charges.
| Method | Cost Per Hour | Cost Per Sq.ft. | Cost per 1,500 Sq.ft. |
|---|
| Soft Wash | $55-$80 | $0.25-$0.35 | $275-$400 |
| Pressure Wash | $50-$150 | $0.30-$0.40 | $300-$450 |
| Power Wash | $75-$100 | $0.35-$0.55 | $400-$700 |
| Manual Wash | Included in other methods | Included in other methods | Included in other methods |
Soft Wash Siding
Soft washing costs $275 to $400 for a 1,500 square foot home with labor costs at $55 to $80 per hour. The project takes two to three hours to complete. The cost per square foot ranges from $0.25 to $0.35. Soft washing is similar to power washing but operates at a much lower pressure. This method combines low-pressure water mixed with a cleaning solution that works safely on brick, stucco 1, and vinyl. Soft washing usually costs less than pressure washing but may not remove everything. Soft washing can be done with a pressure washer as long as the pressure is set for less than 1,000 psi. Pressure washing and power washing will typically use pressure above 1,000 psi.
Pressure Wash Siding Cost
Professional pressure washers charge from $50 to $150 per hour, depending on the siding material and level of dirt. Pressure washing is the most conventional method for cleaning siding. A 1,500 square foot house takes approximately two to three hours, costing $300 to $450. Pressure washing the siding of a house will be around $0.30 to $0.40 per square foot. Manual washing may be done in conjunction with pressure washing and may cost on the higher end of the spectrum.
Power Wash Siding Cost
Expect to pay around $450 to $700 to power wash a 1,500 square foot home with vinyl siding. The labor cost would be around $75 to $175 per hour, with the project taking a maximum of four hours. By square footage, the cost to power wash will be around $0.35 to $0.55. Contractors start out testing the siding with the heat before making a large-scale application. The professional will confirm that the power washer won’t damage the siding. Since power washing requires different equipment and potentially extra hours of labor, the cost is slightly more than pressure washing. The main difference between power washing and pressure washing is the water temperature. Pressure washing uses water directly from the hose, while power washing heats the water first before being applied with a high-powered nozzle.
Manual Siding Cleaning
Manual cleaning involves going in by hand with a brush and cleaners to get rid of dirt. This is appropriate for certain kinds of siding, like wood, as it avoids paint and caulk 2 damage. It’s very unusual to find a professional service that washes siding entirely by hand. Siding should be cleaned at least once a year but possibly more frequently if your siding is susceptible to mold and mildew buildup or if you put your house up for sale. That being said, hand washing certain sections is usually included in the hourly cost of pressure washing.
Siding Cleaning Cost by Material
The cost to clean siding on a 1,500 square foot house ranges from $275 to $500 depending on the type of material. Different types of siding are popular in homes today. Not all can handle the same cleaning method. Review manufacturer recommendations before hiring a contractor to clean your siding. If you use a method that isn’t recommended, you could end up voiding warranty coverage.
| Material | Soft Wash | Pressure Wash | Power Wash |
|---|
| Stone | $275 | $350 | $400 |
| Brick Veneer | $275 | $350 | $400 |

Soft wash is used on vinyl siding when the home is older or doesn’t require a deep cleaning. In these instances, the contractor uses psi under 1,000.
Wood Siding Cleaning
Pressure washing wood siding of a 1,500 square foot home will be around $450, while soft wash will cost about $300. Wood siding tends to attract significant amounts of mold and mildew over time. Since wood siding is fragile and can become damaged, you have to be careful during cleaning, especially in older homes. When a contractor goes ahead to pressure wash wood siding, the professional will likely use a psi lower than 1,000. Soft wash wood siding is preferred since it won’t dislodge pieces of the siding. Most contractors won’t power wash wood siding since heat could discolor or damage the wood.
Clean Stucco Siding
To clean a 1,500 square foot stucco exterior, you’ll pay around $325 for soft wash, $400 for pressure wash, and $475 for power wash. Stucco siding is notoriously difficult to clean. Since the material is porous, the siding tends to easily build up mold, dirt, and pollen stains. Stucco can be damaged if too much pressure is used, so most contractors won’t spray over 2,500 psi. Since stucco does get dirty easier than other types of siding, you will likely have to clean your home professionally at least once a year.

Steel siding is easy to clean using a pressure washer on a medium setting. If the area is very dirty, the professional may consider a power washer since the heat could remove any caked on dirt. Harsh chemicals, especially acidic types, are avoided when cleaning steel siding.
Cedar Siding Cleaning
Expect to pay around $500 to pressure wash cedar siding and $350 to soft wash cedar siding on a 1,500 square foot home. Cedar siding will be managed in the same manner as wood siding. Like a wood deck, a siding with cedar shake will discolor over time due to mold and dirt buildup. When you pressure wash cedar siding, there’s a chance of wood fibers falling off. Preferably, contractors would consider a soft wash for cedar siding with a psi under 1,000. Like wood siding, you won’t typically power wash cedar siding since the heat may be too harsh on the material.
Engineered Wood Siding Cleaning
Since the work is on a specialized material, expect to pay around $380 to soft wash a 1,500 square foot home. According to some engineered wood siding manufacturers, homeowners should not use pressure washers on the material. A pressure washer may damage the finish. Instead, use manual and soft wash methods.
Fiber Cement Siding Cleaning
Expect to pay around $400 to soft wash fiber cement 4 siding on a 1,500 square foot home. The cost is slightly elevated due to the specialized material. According to the manufacturer of fiber cement siding, James Hardie, you can only use non-abrasive cleaning methods. Don’t power wash Hardie siding. You can only use soft wash to clean fiber cement or manual methods such as cleaning with a soft-bristle brush and garden hose.

An estimated cost to soft wash stone veneer on a 1,500 square foot home is $400 or more. Stone veneer is another type of siding that can’t be cleaned with a pressure washer or power washer. The material is too delicate to handle the high amounts of pressure applied during a cleaning session. Instead, only mild cleaners and a polishing tool can be used to get rid of any grime on stone veneer. Ask a contractor about their experience with soft washing stone veneer before hiring the company.
Siding Inspection
Before you clean your siding, you’ll want to make an initial inspection. What you’re trying to do is identify the main source of dirt on your siding. The most common surface buildup problems on siding are pollen, dirt, mildew, or bird droppings. Different cleaners and cleaning methods are more appropriate for different dirt sources. The contractor needs as much information as possible to determine the right cleaning method for your house. Remember to take square footage measurements. Most contractors want an approximate size of the cleaning area.
Remove any decor items attached to your home’s exterior before your contractor appointment. Examples include wreaths, plant hangers, holiday lights, and metal signs. Many homeowners seal windows and doors with caulk before power washing to prevent any water damage. Doors and windows are usually locked before a pressure washing appointment. Contractors may ask you to turn off the power of any outlets and lights located on the exterior of the home. Outdoor light fixtures don’t need removal, but you should cover them with plastic wrap to prevent shortages.
Enhancement and Improvement Costs
Siding Painting Cost
The average cost to repaint the house exterior is $2,500 to $7,000 for a 2,000 sq. ft. house. Before painting the siding, you’ll want to clean away any dirt, mold, or mildew buildup. After cleaning the siding of the house with a soft clean, pressure wash, or power wash, the siding is ready to paint. You may decide that it is a good idea to repaint the entire structure. Remember, the cost of cleaning the siding before painting is in addition to the cost of repainting the home.
Siding Repair Cost
Siding requires regular repairs. Repair costs range from $100 to $1,700 to repair 100 sq.ft. of siding, with most people spending $500 to repair 100 sq.ft. of wood siding.

Vinyl siding repairs, for example, costs about $1 to $2 per sq.ft. On the other hand, wood siding may cost $2 to $34 per sq.ft. Depending on the type of siding, you may have to deal with cracks or peeling paint.
Pressure Washing Windows
Pressure washing windows to clean the glass is $185 to $400 per project to pressure wash windows, depending on the location of the window and size. Cleaning the windows is a great way to enhance your home’s appearance, especially after cleaning the siding on the house. Also, removing the dirt and debris buildup on the glass’s surface allows natural sunlight to enter the home. When pressure washing a window, be sure to stand at least three to five feet away from the window to avoid breaking the glass. Pressure washing windows requires low pressure to prevent damage or breakage. A wide-angle nozzle of 25 to 40 degrees is used with a psi of 1,200 to 2,000.
Cost to Pressure Wash a Deck
The average cost to pressure wash a deck is $100 to $200, depending on the deck’s size and its material. Use low pressure when cleaning soft woods.

High-pressure washing should be used with caution because it can damage loose roof tiles or shingles. If using pressure washing to remove moss from the roofing, remember that you also have to use a herbicide to kill the moss, or it will just grow back.
Pressure Wash Patio Cost
The cost to pressure wash a concrete or similar durable material patio that measures 50 square feet averages $50 to $75. If the patio has grout lines or fine details, then the cost might be on the high end of the spectrum. Discuss the complete cost for effectively cleaning the surface of your patio with the pressure washing professional. Cleaning the patio at the same time you clean the siding of your home gives it an instant new facelift.
Additional Considerations and Costs
- Cleaning products. Several cleaning products are appropriate for siding, but you should take some precautions. Avoid using abrasive brushes, which can damage the siding. Also, you should avoid using cleaners with organic solvents, undiluted chlorine bleach, or solvents like furniture polish or nail polish remover. All of these types of substances can damage your siding.
- Mold and mildew. The buildup of mold and mildew on siding is unsightly, which is a great reason to clean your siding. However, it could also be detrimental to your health. If your children are playing outside, they could develop health problems from exposure to mold. In addition, mold and mildew, though it starts on the outside, can potentially make its way into the house. Attics are particularly vulnerable to mold and mildew that start outside.
- Debris damage. Any buildup of mildew, mold, or dirt can cause staining and damage to siding if left uncleaned for an extended period.
- Cleaning the home’s exterior. When cleaning your home’s siding, you may want to consider a complete top to bottom refresh. Consider hiring a contractor to tackle other types of exterior cleaning, such as cleaning the fascia and soffits. You may also want to schedule your gutter cleaning before having the siding pressure washed.
- DIY. Yes, you can tackle cleaning your home’s siding as a DIY project, especially if you are carrying out a soft clean. However, if you want to have the home’s siding cleaned with a pressure washer or power washer, you should consider hiring a professional. The high burst of water can damage the surface of the siding if not handled correctly. A power washer uses heat to clean the surface of the siding, and some siding material cannot be safely exposed to the high heat of a power washer.
- Permits. Typically, you do not need a permit to have your home pressure washed, power washed, or soft cleaned. However, you should always check with your local municipality to confirm. Often HOAs, small neighborhoods, and private communities have their own set of rules that pertain to pressure washing. In some cases, a permit might be required due to the amount of water being used. Whenever you work with a reputable company, they will typically check on required permits.
- Estimates. There is a lot of competition for siding cleaning services. Do not hesitate to get estimates to determine how much the professional company will charge you to clean the siding. Ideally, you should get at least three estimates. Pick the modestly priced estimate and forego the high and low priced estimates.
- Sandblasting vs pressure washing siding. Pressure washing uses a heavy jet of water to clean the surface of siding. However, sandblasting combines water with an abrasive material mixed with water to lift away dirt, debris, old paint, or scratches on metal. Typically, pressure washing does not harm the surface of the siding, but sandblasting can cause damage and leave behind marks. Sandblasting is normally used to clean metal or other tough materials that can stand up to the abrasive nature of the process. Sandblasting is often used before painting to remove the old paint from the siding.
