What is a high pressure wash

a high pressure wash This is where we crank things up a notch to remove stubborn moss and mould or to remove loose paint for pre-paint preparation. This method is also great for cleaning driveways, slippery steps,removing oil stains from concrete, cleaning gutters and spouting and removal of unwanted plant growth from the gaps in paving and patio areas. We have a range of nozzles that provide a gentler clean when needed for use on softer materials like a wood fence.

What is a chemical wash

We use a chemical wash when a little bit of oomphis needed to remove heavier build ups of grime, allege and mould. The processis similar to a soft wash only a stronger chemical is used.

>

What is a soft wash?

Soft washing is the gentlest method for removing mould and grime using bio degradable MAF approved detergent.  The detergent leaves a wax coating to repel mould growth and leave a sparkly shine.The wash is carried out using a nozzle on the water blaster gun that ensures a low pressure application of water in conjunction with turning down the power on the water blaster. When required we also use a water broom to loosen grime. This service is perfect for routine cleaning every 4 to 12 months.

Do I get charged for travel?

It depends where the property is located. We charge 40cents per km from the outskirts of Whangarei as defined by google maps. If the property is in Auckland please make contact so we can discuss if there will be a charge or not.

>

What is the cost of a roof wash?

The cost of a roof wash is dependent on how many square meters the roof is, how steep the pitch is, how accessible it is and how dirty it is. An alternative option is for to treat the roof instead which it's much quicker for us to do and therefore often a cheaper option.

If you are on tank water we will disconnect the tanks so that none of the dirt or cleaning product we use gets into the tank. You will need to leave your tanks disconnected until you have had 25 mm of rain.

If you have skylights we can also wash these while we're washing the roof. We have specialised brushes to gently wash skylights.

If you can let us know how big the roof is, where the property is located, and what the roof is made out of we will be able to give you a price.

>

What is the cost of a house wash?

There are a lot of factors that determine the cost of a house wash for example the size of the house to be washed, whether it's split level, single level or multi-level, how accessible the house is. Another factor that we take into consideration is how dirty the house is, and what sort of mould is on the House. For example, pink mold can take a lot longer to clean off than other moulds.

Also taken into consideration is if the job includes water blasting concrete around the house, washing a garage, decks,patios and porch roofs. We price these things separately So make sure you let us know if you want any of these items priced and washed.  

Low water pressure will also affect the price as this can mean the job takes a lot longer to complete. If we quote a job and then find that the water pressure is not very good we will need to adjust the price. When this happens, we always contact the person who engaged us to complete the job to let them know the change in price and to check they would still like us to proceed.

Roofs, gutters and drain unblocking

>

What is involved in unblocking gutters and what happens with the gunk you clear from the gutter?

When we unblock gutters we clear out all of the debris and take it away from your property. If you are having your gutters flushed out and you are on tank water we will disconnect the tanks while we complete the freshwater flush and reconnect them afterwards.

>

What is a roof treatment?

A roof treatment uses a product to clean the roof as opposed to a water blaster. The product gets sprayed onto the roof surface and is designed to kill lichen and moss. The rain and sun gradually break down and remove the dead lichen and moss. This process can take up to 12 months and generally results can be seen in the first month.

The alternative to a roof treatment is a roof wash. In some cases, this can be done from the ground. Alternatively,we get up on the roof using our harnesses and safety gear and gently wash the roof using low pressure. If you have a tile rood we generally recommend a roof treatment.

General questions

>

How often should I have my house or commercial building washed?

It is a good idea to wash your house or commercial building at least once a year to extend the life of your paint 20 to 25% longer. Many clients opt to have their properties washed 2 or 3 times a year to keep them looking good and to eliminate spider webs.

If however you live in a coastal area you should look to have your property washed at least 2 times a year or more depending on how close you are to the sea. This assists with any coastal breeze erosion.

It is also important to note if any of the materials used to construct your house or building have a warranty. If so, these materials must be washed according to the warranty specifications so that the warranty does not become in valid

>

I heard that washing a house or building on a regular basis makes the paint last longer. Is this true?

Yes washing once or more a year will increase the life expectancy by 20 to 25%. Paint manufacturers have carried out many studies to back this up. And it is much cheaper to get a regular wash than repaint more often you need to.

>

We want to repaint our house. Can you strip away the paint using water blasting?

Water blasting to strip paint is not something we recommend. However, we do recommend and offer a pre paint wash which will loosen and remove any paint flakes making it easier for the pre paint preparation. A lot of residential and commercial house painters will use our services prior to them starting the job.

>

Does water blasting a house or building remove moss, mould & lichen?

Water blasting alone will not kill and remove Moss mould and lichen. We apply a solution that is 50% stronger than most over-the-counter products and will keep the surfaces free of moss, mould and lichen for longer.

>

What should I do to prepare for my home to be washed?

Make sure there is no washing hanging on the line, if you have pots and plants or furniture that is likely to get in the way please move it out of the way. If you have a dog, please ensure the dog is contained.

If you are in an older house with wooden joinery it is a good idea to put towels down on the inside of the windowsills.Please also ensure that all windows and doors are shut.  

>

I am an absentee owner so how will I know you have done a good job?

We have many absentee owners and are more than happy to take before and after photos at your request. We are also more than happy to do a pre and post wash report on any damage we notice for example broken gutters or down pipes, rusting roof. This can be particularly useful in areas which cannot be seen easily from the ground and if an issue is caught early enough it can save thousands in damage.

>

Do I have to be home when you wash my house or property?

No you do not have to be home when we wash your house or property. Just remember to close all your windows and move anything away from the house that you do not want to get wet.

>

Will you provide a discount if I have more than one property to wash?

Yes we will definitely provide a discount if you have more than one property you want washed.

>

What is included in a house wash?

The following is not included in a house or building wash: If you would like other items washed such as the roof, decks, driveway, paths, patios, garage or other detached buildings we price these separately.

Clearing out gutters also gets priced separately.

>

Do you wash cow sheds or farm implements?

We sure do. Pete was a dairy farmer for over 20 years and so Loves an excuse to get back on the farm

>

Can you freshwater flush my windows after you have washed my house or building?

Yes we can flush windows after we have washed a house or building and in most cases we will do this as part of a house wash.

Will it cause damage?

>

Will water blasting my property make paint chip off?

The paint will only chip off if the surface that is being washed has a good paint finish. This is because we never use a high pressure wash on painted or natural wood surfaces. The nozzles we use are different to that of a domestic water blaster and enable us to do a much gentler wash. We also apply a cleaning product to the surface prior to doing a soft wash which loosens any dirt, grime and mould.

We apply a wash-down product before the wash that does a lot of the work and loosens girt, grime and mould. We then use special nozzles when we wash cladding, enabling us to do a soft wash. We will apply a slow-release agent to the areas on the cladding where the paint is peeling or looks fragile instead of a wash. This means that it will not look clean in these areas after they finish, but the mould etc, will disappear. Sometimes it can take a few weeks till it cleans up, depending on the type of mould and the severity.

We cannot guarantee that no paint will chip as it depends on the paint's integrity, but we take significant measures to avoid it from happening. If a bit comes off in an area, this is when we stop washing and treat the area instead. 

Paint that is old and has been compromised by mould or other factors will often have stains that we cannot remove.

>

Will water blasting damage my wooden surfaces such as deck or wooden cladding?

No, if the operator has had the correct training in washing techniques and using the machinery and tools correctly. Using commercial grade purpose-built equipment combined with the correct low pressure is important to ensure there is no damage. We also have a variety of nozzles that we use and change for different surfaces. All our guys are thoroughly trained in the correct washing techniques and how to operate the gear.

>

Are the cleaning products you use harmful to plants, pets, people or my pool?

To answer this question, we will look at each of the individual items separately.

Plants - The cleaning product used can damage plants if the operator does not apply it in the correct manner. If you are concerned about your plants let us know. We can wet any plants close to the area that is being washed with water to dilute the solution to avoid any damage. We can also then gently rinse the plants afterwards and we can use a diluted mix of our wash down product.

Pets & people - Once again the answer to this is yes if the operator does not know what they're doing. It is important that the cleaning product is mixed at the correct ratio with water to ensure a safe dilution. All the Blast Away Guys team is thoroughly trained on how to do this.

Pool - No the product we use will not damage your pool. If we're cleaning around the outside of an in ground pool every effort will be made to stop debris from being washed into the pool.

Commercial, schools and educational centres

>

How long will it take?

The answer to this question depends completely on the size of the building, the scope of work and how many people we put on the job. If you have a specific deadline, you would like the job completed by, let us know at the time of quoting so that we can do our best to ensure we can meet your needs. When we quote, we can also indicate how long we think the job will take.

>

How will you manage health and safety?

We assess each commercial job individually to ensure we consider all aspects of health and safety relating to the job. Some of the things that we consider are: 

  • Does WorkSafe needs to be notified
  • Is traffic management required
  • Are spotters are required 
  • What are the safest times to complete the work for the public and people that work within the building 
  • What access equipment may be required and what health and safety procedures need to be followed in accordance with the access equipment 
  • What health and safety equipment will be required 
  • How can we mitigate risks

This will be considered, discussed and captured in our Job Safety Analysis. We also keep a Hazard and Risk Register, Incident and Injury Register, Chemical Resistor, Safe Operating Procedures and carry out Monthly Maintenance Checks

>

When can you do the job?

Our team of 10 means prioritising jobs based on urgency for clients. It also means we can get larger jobs finished in a shorter time, minimising disruption for business.

We like to be as flexible as possible and prioritise work based on client needs. If you have a deadline, let us know, and we will see what we can do to prioritise your job. We also have contractors and partners who can provide other services should it be required.

>

Will you do this during business hours or after hours?

This depends on where the business is situated and what other businesses or residential property are in the area that could be impacted by the work being carried out.

If a commercial property has busy main entrances and/or loading bays, we will often wash those areas before the business opens and then continue to complete the other areas once the business is open, provided it does not impact traffic or pedestrians.

Sometimes having a spotter at the main entrance while the business is open can work well, provided there is no heavy foot traffic.

If we need to have access machinery on the road, we will need to get traffic management to help ensure the public's safety. This work is almost always completed at night, and during periods when traffic is at it's quietest.

>

>

Do you provide a post wash report?

Yes we can definitely provide a post wash report this would include comments on the overall condition including pre wash state and problem areas such as heavy lichen and rust. We also report on the overall condition of the building and materials. This can be particularly useful in areas which cannot be seen easily from the ground. In many cases this has saved building owners thousands because issues are spotted before they cause expensive damage.
