All you need to know about jet washing a patio including costs of materials, labour and time frames.
A good pressure washer can make short work of cleaning your patio and help to stop them looking grainy and becoming slippery to walk on full stop paths and patios can, of course, be cleaned using a scrubbing brush and a hose, but a pressure washer is much quicker. Prices for good pressure washers have reduced considerably in recent years so it is now feasible for homeowners with large drives or patio areas to have access to their own pressure washers for cleaning. However, professional pressure washers are much more powerful and effective. Therefore, many homeowners will simply hire a local contractor to come in every year or so to do the pressure washing for them.
Cleaning a driveway properly using a pressure washer will remove algae, weeds and stains. Once a driveway or patio has been pressure washed and is completely cleaned and dry, joints can then be refilled using kiln-dried sand if necessary and a driveway sealing product can then be used for protection.
When having your driveway or patio areas cleaned you may also want to consider cleaning other areas at the same time. The companies which offer driveway and patio cleaning will normally offer other brick and Masonry cleaning services such as any walls which are adjacent to the driveway, which will finish the job off nicely and avoid having a lovely clean drive which looks brand new being bordered by grubby and grimy walls!
When cleaning a drive or patio yourself using a hose you need to make sure the hose is securely attached to the tap and be prepared for a lot of hard work! Using a pressure washer purchased from a local DIY store makes the job much easier, but unless you are willing to spend a fortune, the pressure washer you buy will not be anywhere near as powerful as the systems used by professionals. But as long as the grime and dirt are pretty superficial, the DIY solution can be quite effective. But for seriously ingrained dirt and major algae or moss problems, get a professional in with a heavy duty system and all the right chemicals to make a good job of it in a fraction of the time it would take you with a cheap pressure washer and over the counter cleaning supplies.
When using a pressure washer make sure you fit the appropriate lance and ensure all connectors are tight and there are no leaks. Follow the manufacturers instructions carefully and wear goggles for eye protection. Clean by working from one corner blasting the grime away in a sweeping motion, use detergent and biocide as necessary and then rinse off using a lower water pressure. If you can afford it, choose a pressure washer with variable power settings so you can clean different surfaces without causing any damage. Also, it is worth paying extra for a washer with a long hose so you don't have to keep moving it as you clean.
Using a broom or garden hose is the safest way to clean drives and patio areas, but in the case of oil stains, ingrained grime, algae or mould growth, a broom alone will not be enough. But power washing, though a fast way to clean hard surfaces, can cause significant damage to concrete bricks or paving if carried out by an inexperienced user. Turning on a pressure washer, aiming and pulling the trigger is pretty simple, so everyone assumes that is all there is to it! But pressure washers are powerful machines which can cause property damage and even serious injuries. If you use a pressure washer but choose the wrong nozzle or use higher pressure than is required, you could end up causing some expensive damage which will completely wipe out any possible savings you hoped to make by going the DIY route!
In terms of material costs, there aren't any as the tradesman will provide this themselves. Usually they will need to use your water supply but any chemicals and tools will be brought with them. These materials are not too costly and will be factored into the overall price.
The average specialist will usually charge around £100-£150 per day and will take anywhere from 4 to 12 hours to jet wash a patio depending on the size, and whether or not it needs resanding or sealing.
Below are some estimated costs to have your patio pressure washed:
|Job Description||Avg. Cost||Duration|
|Small Patio||£150 - £200||3-4 hours|
|Medium Patio||£200 - £300||5-6 hours|
|Large Patio||£300 - £400||7-8 hours|
