How long have you been in business?

Are you insured?

Yes, of course!  Every professional exterior cleaning company should have the necessary insurance and Worker’s compensation insurance is also important as you don’t want to be liable for injuries that could occur although it is highly unlikely. They are companies that hire employees as contractors and this is usually a grey area as far as worker’s compensation is concerned. Ask the right questions and make sure you’re not liable for any injuries that might be sustained.

Is there a difference between cold water and hot water pressure washing?

Yes. There are several advantages to offering hot water pressure washing capabilities, which we do. Hot water is a natural disinfectant. Therefore, when cleaning a surface with hot water, it does not only clean the surface, but it also kills bacteria such as algae. This keeps the surface cleaner for a longer period of time. Imagine cleaning your dishes with cold water – much less effective. Additionally, hot water has the ability to cut grease. This makes hot water pressure washing very useful in places such as parking garages where cars tend to leave behind greasy fluids from things like oil or transmission leaks. Unlike cold water pressure washing, hot water can remove gum by melting it off the surface and it makes it possible to pressure wash in colder weather. As long as the temperature is above 32 degrees, the surface can be cleaned with hot water.

What is the difference between power washing, pressure washing and soft washing?

All of these terms basically describe the same thing, exterior cleaning services. The terms “power wash” and “pressure wash” are very similar, but there are a few distinctions. Power washing utilizes the same idea of blasting water at a high pressure, only with hot water. This sets power washing apart because the hot water not only acts to sanitize surfaces, it is also superior at breaking down hydrocarbons and organic materials.

So power washing (hot water systems) are usually used for cleaning sidewalks, driveways, stone walls, parking garages, building exteriors and concrete. They are more commonly seen in commercial and industrial settings or cleaning concrete at residential properties.

Pressure washing is “All About The Pressure” How much PSI and GPM the machine uses dictate how effective it is to clean but it is not a very efficient process.  The pressures are high enough to be dangerous to people and the surface being cleaned. Amateurs often learn the hard way about the cutting power of a pressure washer when cleaning a wood deck or worse.  The water is pushed out at such a high rate, it can cut through skin to the bone in a split-second. It can also strip paint off siding.  Usually pressure washing is best used in industrial situations to remove coatings.

Soft Washing

The term Soft Washing was created for marketing purposes, in most cases “Soft Washing” is actually performed with pressure washers, but the pressure has been reduced, and chemicals are combined with “Low Pressure” to clean surfaces.  This method is a LOT FASTER, but if it is performed incorrectly by someone with very little training they can oxidize painted surfaces and kill landscaping.

Soft Washing is done using less than 500 PSI for rinsing or chemical application. The contractor will use a HVLP system which means High Volume Low Pressure.  It is performed with equipment that puts out less pressure, or the tip of the pressure washer is replaced with one that has a larger orifice and widens the spray from a laser beam to a fan of water. uses a Hybrid system that we developed 31 years ago that combines hot water, professional grade cleaning solutions designed to break down mold, mildew and surface dirt and “High Volume” water.  By combining all three methods together, the hot water makes our cleaning solutions work better, so we use less “Chemicals” which is safer for the environment, we can apply cleaning solutions and rinse them from surfaces much faster, so our process is more efficient and safer than all three of the other methods.

What are PSI and GPM? uses “Low or NO” pressure process for cleaning.  We use Environmentally friendly cleaning solutions that are designed to break down mold, mildew and surface dirt so they can be rinsed away without using any pressure.

PSI is pounds per square inch. This is what delivers the cleaning power during a power wash, forcing contaminants off the surface.

GPM is the gallons per minute. This flushes the contaminants pushed off by the PSI.

Both are very important. Some people do, however, prefer more PSI or more GPM depending on their needs. A farmer may want more GPM to flush contaminants away from the fresh soil; a business owner may want more PSI to get the grime off the exterior surface of his or her storefront.

However, using pressure is NOT recommended by the Power Washing Industry Standards.

Health Benefits of Professional Washing

Giving your home or business a deep cleaning is important, not just for aesthetics. Your health is impacted by the long-term build-up of dirt, mold, pollen, algae, and decaying matter. All that stuff piles up over time in between cracks, underneath sidings, around stones, and on patio furniture.

Can you give me a quote over the phone without seeing my house?

Yes. Our trained professionals know what questions to ask in order to gain the information needed to give an accurate quote. We also use city records to obtain the square footage of your home to aid in this process.

Why is insurance important to me as a homeowner?

Many contractors state they have insurance, but few actually have more than an automobile policy. Damage can occur to your home by a contractor, or a worker could be injured on your property, and you could easily be held responsible. Always ask for proof of insurance… that little question could save you thousands of dollars.

I received another company’s coupon offering very low prices, are your services more expensive?

Low priced offers, according to the Better Business Bureau, result in the most complaints and unresolved problems reported to the BBB. We take pride in creating long term relationships with our customers. This is the result of our excellent customer service.

Are all power wash companies alike?

Anyone can purchase a pressure washer. Simply owning a pressure washer and advertising that you offer a service doesn’t mean you can operate it effectively. A pressure washer in the hands of an unskilled operator will do a great deal more harm than good. We have seen decks ruined by too much pressure and harsh chemicals, siding blown off houses, plants and yards killed, windows broken, and even new paint peeled.

My contractor said my siding and deck were zero maintenance.

Low maintenance yes, zero maintenance no. Anything left outside in this area’s humidity and sun will get dirty. Your car gets dirty sitting in your driveway and so does your deck.

How long have you been power washing?

Since 1989, we have been a full-time professional pressure wash and deck staining/sealing contractor. We do not have sideline businesses that would distract from giving our customers the finest exterior cleaning services.

I am concerned about the amount of water you will use.

Our low pressure heated cleaning method uses less water than other types of exterior cleaning. A typical exterior house wash uses approximately $5.00 of water, which has already been subtracted from the cost of the service.

Why should I get my house professionally washed?

Getting your house professionally washed is a great way to make sure it stays clean and maintained, while also reducing the amount of work you have to do. House washing offers a variety of benefits that can help keep your home looking its best.

First, professional cleaners are trained in the most efficient and effective techniques for cleaning various surfaces in your home. They specialize in removing stubborn stains, dust, dirt, and other grime from carpets, floors, and furniture quickly so that your home looks neat and tidy. Additionally, they use specialized tools that allow them to reach hard-to-reach areas of your house like corners or behind radiators – something you may not be able to do yourself when doing a DIY job at home.

Professional cleaners also understand how important it is for your household items to be cleaned properly without damaging them. They take extra precautions such as using special solutions or vacuums designed for different types of surfaces in order to avoid any potential damage during the process. This helps prolong the life span of valuable objects around the house like carpets or furniture. Plus, having professionals handle this task ensures that each surface receives proper treatment without unnecessary stress on you!

How often should my driveway be professionally pressure washed?

Pressure washing your driveway is an important maintenance job and should be done by a professional at least once a year, although more frequent cleanings may be necessary depending on how often the area sees heavy foot traffic. This level of regular maintenance will help to protect your property from any staining or damage that can come from dirt, grime, oil, and other contaminants. A professional pressure washer will use specialized equipment to safely remove debris without causing harm to your driveway’s surface. Additionally, they are able to use detergents that can eliminate any mold or mildew build-up in the cracks of pavement and around edges for ultimate protection against unwanted elements. If you live in an area with particularly harsh weather conditions or a lot of traffic, it might be wise to schedule professional pressure washings every 6-8 months for maximum results.

Is it safe to pressure wash a roof?

Yes, roof pressure washing is considered safe if done by a professional. Pressure washing a roof can help remove the buildup of dirt and debris which can leave your roof looking brand new. It is important to remember that not all roofs are suitable for pressure washing and it’s best to talk to an experienced professional who knows the type of material for the job to be done correctly. In addition, it’s best practice to use detergents approved for use on specific types of roofs as improper cleaning agents may damage shingles or tiles. Lastly, always make sure that proper protective gear (such as safety glasses) is worn and that no one goes up on the wet rooftop during or following pressure-washing activities. When done correctly and safely, pressure washing helps keep your home’s exterior looking great!

How do I find the best power washing company near me?

Finding the best power washing company near me can be a daunting task, but it doesn’t have to be. To begin with, look for companies that are professional and knowledgeable in the power washing business. They should be familiar with different methods of power washing and able to provide you with both quality workmanship and customer service. Additionally, try ones that offer competitive prices as well as services such as upholstery cleaning or window cleaning.

Next, take some time to research reviews online from previous customers who have used the same power washing company you’re considering. Word-of-mouth recommendations from friends or family members can also help lead you in the right direction if they’ve had a good experience with their power washing service in the past.

What is a soft wash house cleaning?

Soft wash house cleaning is a professional process that utilizes the power of low-pressure washing to safely and effectively clean and maintain your home’s exterior. It uses highly specialized cleaning agents and equipment, including an adjustable pressure washer with an array of attachments enabling homeowners to soft-wash everything from wood decks and fences to siding, eaves, windows, driveways, patios, walkways and more. Soft washing relies on the precise application of water mixed with gentle soap or detergent at low pressure in order to achieve effective results without damaging any surface.

Why should I hire a local power washing company over a national one?

Hiring a local power washing company has several advantages over a national one. For starters, you typically get a much higher quality of professional service from the local provider because it is more invested in providing exceptional customer service due to the close contact with its customers and community. With a local business, you have direct access to the owner or customer service staff who can give personalized attention to your needs and answer any questions or concerns you may have about their services.

Additionally, since most power washing companies are family-owned and operated businesses, they will likely be more knowledgeable about your area’s unique terrain when it comes to pressure washing as well as being able to better customize products and services that meet your specific cleaning requirements. Since they live and work in the same area as you, they will also know what methods best fit each type of surface so that nothing gets damaged during the process.

Is it safe to power wash my house?

The simple answer is yes, it is safe to power wash your house under the right circumstances. However, as with any home improvement project, there are certain risks involved that should be taken into consideration before starting.

House power washing can be an effective way to remove dirt and grime from the exterior of your property while ensuring no damage is caused in the process. Properly conducted power washing will ensure that paint, brickwork, and other materials are preserved for years to come. It’s also less labor-intensive than manually scrubbing your walls with a soapy brush or sponge!

What is soft washing and is it different than power washing?

Soft washing is a cleaning method that uses a mixture of low-pressure water and special cleaning products designed to achieve the desired result without causing any damage. It is different from power washing, which uses high-pressure water for deep cleaning.

Soft washing is great for many surfaces including outdoor buildings, roofs, walls, and pavements. Its gentle yet effective action means it’s ideal for use on painted or delicate surfaces such as wood siding and vinyl windows without damaging them in the process. This makes it perfect when you need cleaners to be used around children or pets too!

The most notable benefit of soft washing over traditional power washing is its ability to remove mold, mildew, and algae without needing excessive scrubbing or using harsh chemicals like chlorine bleach often found in many traditional power washers. The combination of mild detergents along with low-pressure water creates a foam that attaches itself to dirt particles on contact making them easy targets for removal. The long-lasting results are what make this technique preferred for many homeowners who want cleaner results than traditional methods can offer especially when dealing with organic material like moss growths on roof shingles or decks surrounding pools where safety concerns come into play due to how slippery they become after numerous heavy rinses by pressurized waters.

How often should I clean my gutters?

Gutter cleaning is a necessary task for all homeowners to keep their homes safe from water damage. Depending on the size of your home, its location, and the size of your gutters, how often you should clean them can vary greatly. Generally speaking, it is recommended that homeowners clean their gutters twice a year: once during the fall before freezing temperatures set in and then again during the spring when leaves have started to bloom again on trees.

However, if you live in an area with large amounts of rainfall or near hardwood trees that consistently shed leaves throughout most of the year – such as oak or maple trees – you may need to do extra gutter cleaning more regularly during those seasons. Plus, if there are any issues with clogging due to debris buildup or animals taking up residence in your gutters; it’s best to address these problems right away rather than risk even more costly repairs down the road.

Gutter cleaning isn’t always easy and depending on what type of system you have installed it might require professional help — especially for those who do not feel comfortable getting up on ladders or working at heights — so be sure to research properly about what kind of routine maintenance is required for your particular setup. Even though gutter cleaning can be tedious work; making sure they remain unclogged will save you money over time since clogging can cause serious water damage that will cost far more than having routine maintenance done twice a year.
