Types of Pressure Washing

We’ll now look at the different pressure washing jobs mentioned in this article in more detail. We’ll discuss what these jobs involve, how much they cost, and what their pros & cons are.

Pressure Washing a Driveway

This work generally involves a relatively inexpensive jet washing task, in which a relatively small area (the average driveway is about 10 ft x 20 ft in size) is cleaned with a pressure washer.

Driveway pressure washing

The average cost of this work is £100 to £150. However, to clean and seal a driveway would cost around £250 to £400.

Pros:

✔ Relatively inexpensive

✔ It can make for a nice welcoming aesthetic for visitors

Cons:

✖ Heavy-traffic driveways can get dirty again fairly quickly

Pressure Washing a Patio

You may wish to have your driveway pressure washed instead of (or in addition to) other types of jet washing. Again, this is a relatively inexpensive and simple job compared to pressure washing a roof or/and pressure washing a house. Pressure washing a patio tends to cost between £150 to £400.

Patio pressure washing

Pros:

✔ Relatively low cost

✔ Can really freshen up a garden

Cons:

✖ Water could get onto the lawn unintentionally and damage the grass

Pressure Washing a Roof or House

One of the most common forms of pressure washing is to clean a roof or/and the exterior of a house as a whole. Though prices will vary, pressure washing a roof is likely to cost between £200 and £250. You can expect to pay several hundred pounds more for a more extension clean of your property’s exterior.

Roof pressure washing

Pros:

✔ Can achieve a striking improvement to a property’s appearance

Cons:

✖ It can be quite expensive

✖ Not always well-suited as a DIY job (for safety reasons and more)

What Does Pressure Washing Involve?

Though the process of jet washing will vary from surface to surface, there are some broad similarities for each job. In this section, we’ll lay out the steps involved in pressure washing.

Please note that if pressure washing a roof, ensure that the tiles will not be damaged. Some roofing materials will not be strong enough for certain levels of jet washing pressure. So this must be looked into before work begins.

1. Hiring a Contractor or Pressure Washing Service

You may decide to pressure wash a surface by yourself. However, if you’d prefer to hire a professional, sourcing the right person/company for the job will be the first step of the process.

When doing so, you should obtain three quotes at a minimum and some references from each of the contractors/pressure washing services before making a choice.

2. Prepare the Area

On the day of the jet wash, it’s essential that the work area is prepared. This would involve things like setting up a ladder if working on a roof or clearing the driveway.

Of course, certain safety steps (especially if cleaning a roof or otherwise working at a height) will need to be taken here and perhaps throughout the work.

3. Pressure Washing

Some additional work may be needed in the lead up to jet washing. For instance, a degreaser may be used to break apart heavy stains on a driveway. Different tools could be employed to achieve this.

Then, the pressure washer itself must be prepared. The pressure washer must have the right nozzle (per the manufacturer’s instructions) before jet washing may begin.

The spray wand must be fitted to the pressure washer alongside the pressure hose. A garden hose may provide the water, although the exact details will depend on the type of pressure washer in use.

Person pressure washing

At the point in which the jet washer has been filled with a suitable detergent, the tradesperson/pressure washing company employees will add safety gear (if they haven’t already). This would comprise safety glasses, boots, and protective gloves.

The entire area can now be pressure washed. It is best to sweep back and forth using the jet washed detergent. Next, the detergent should be given about 10 minutes to half an hour to soak.

Then, the detergent may be rinsed off by using the jet washer’s rinse mode. The same pattern of washing may be used as with the detergent application. This will allow the detergent as well as remaining stains to be washed away. Of course, heavy stains may take longer to remove.

As soon as the area has been cleared, it should be given time to dry.

If it is to be sealed in the case of a driveway, it should be given time to dry before sealing can occur. An extended paint roller can be used to apply the sealer per the instructions of the producer. Then, you should wait a minimum of 24 hours prior to driving on your driveway after the sealer has been added.

4. Additional Work

There are some additional jobs you may choose to pay for, along with having a part of your property pressure washed.

Let’s look at the price of some relevant examples.

The Cost to Install a Driveway Gate:

  • Sliding hate - £800 to £1500
  • Bi-fold timber gate - £1500 to £3000
  • Bi-fold metal gate - £500 to £900
  • Farm gate - £600 to £800

The Cost to Install a Home Charging Station:

  • Average charging station - £200 to £400

The Cost of Roofing Work:

  • Repointing a chimney - £400 to £600
  • Fitting a new chimney cowl - £150 to £400
  • Replacing the chimney leadwork - £500 to £2500
  • Chimney liner cost - £700 to £900

DIY Pressure Washing

Is it okay to pressure wash as a DIY job?

Yes, it is generally fine to do so. However, you should only take on this work if you know exactly what is involved. You should ensure that you follow the necessary safety steps before proceeding with a DIY jet wash.

However, you should note that it’s generally better to hire a professional if you’re looking for the best results.

Man pressure washing

Building regulations and planning permission approval are unlikely to be necessary unless you plan to undertake additional work along with pressure washing.

If you have any doubts, please contact the local council. For more information on building regulations and planning permission for England and Wales, you can visit the Planning Portal. The rules may differ in Scotland and Northern Ireland.

Hazards and Dangers of DIY Pressure Washing:

  • Falling from a height
  • Damaging surfaces (e.g., destruction caused by pressure washing roof tiles)
  • Working with hazardous materials (e.g., greasing materials)
  • Dealing with the power of the jet wash itself
  • Carrying momentum from a power washer (e.g., jet washing a roof and being pushed back by force)
  • Incorrect or insufficient pressure wash

Potential Problems and Pitfalls

There are some general downsides worth taking into account when it comes to jet washing, regardless of the type of jet washing job you are undertaking or paying for.

Disadvantages of Pressure Washing:

  • It can be time-consuming
  • May prove a bit expensive
  • Difficult to pull off ideally as a DIY enthusiast

In the unlikely scenario that building regulations or planning permission approval is required and your proposal is not approved, you would simply need to apply a second time but with the relevant alterations made to your plan(s).
