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 it true my garage can experience severe damage from a lack of pressure washing?

Pressure washing horizontal surfaces is crucial in areas that experience colder climates and require salt application on the roads and sidewalks during the winter. Salt is extremely corrosive and can cause surfaces, such as concrete, to quickly deteriorate.

In examples such as parking garages where there is rebar or tension cables within the concrete, the salt can actually compromise the integrity of the floors as it deteriorates the metal and causes the concrete to crack. This can be prevented with a regular pressure washing maintenance cleaning every year. We also recommend applying water repellent to concrete floors in order to further protect the surface and prevent water penetration issues.

Do you perform large façade cleaning work?

Certainly.  Some of our largest projects have been cleaning the DC Armory, the Lincoln Memorial and the Jefferson Memorial among Thousands of other large buildings in Maryland, Virginia and Washington DC.

Can you remove efflorescence?

Yes we can clean affected surfaces, but efflorescence is typically a sign of other underlying water intrusion related issues, this condition often can reappear if the source(s) are left unidentified and untreated. Our Exterior Building Services professionals can assist with helping to identify and address these issues.

Can you remove graffiti and efflorescence?

Absolutely. Not only can we remove all paint-based graffiti, but we do it safely. In some instances, graffiti may be found near vegetation or other sensitive surfaces. With our environmentally friendly graffiti removal products, we can get rid of the graffiti without damaging the surrounding area.

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 can I expect my parking garage to look like after you pressure wash it?

Cleaner!  When pressure washing garage floors we have two levels of cleaning – we either use the high pressure wands to do what we call a “pressure rinse” or we use a device called a “walk behind” or “surface cleaner” and 200 Degree water to clean a little deeper. You can expect the surface cleaner to get your garage a newer look than just the pressure rinse.

How often should I pressure wash my parking garage?

Typically, it is recommended to have your garage pressure washed AT LEAST once per year to maintain cleanliness. It is also common to pressure wash once in the spring, usually April (post winter) and once in the fall, late September-October.

There is also the option to do a power rinse down of your garage which is about 65% of the total price of a standard garage power washing. The difference lies in the treatment of oil/grease spots in the garage. The rinse down targets loose contaminants on the deck surface but will not treat any of the staining. Therefore, if you wanted to do a standard wash once per year, you could always follow with a rinse down later in the year to target the excess dirt/loose contaminants which will undoubtedly find itself on the surface through the seasons. Obviously, the amount of traffic your garage receives affects the above.

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.

PowerWashCompany.com 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.

Will high pressure wash damage my home?

YES HIGH PRESSURE WILL DAMAGE YOUR HOME! But the “Low or NO” method that PowerWashCompany.com uses is perfectly safe. The professional technicians at PowerWashCompany.com know how to properly clean surfaces using the Power Washing Industry Standards.  Most companies in the area use high pressure cleaning methods to produce an extremely high pressure output.

What are PSI and GPM?

PowerWashCompany.com 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.

Can I do the power washing on my own?

While power washing can be viewed as a do-it-yourself project, there is a clear distinction between a DIY crew and professional services. This means you get greater capability of equipment and greater expertise by having trained power washing technicians do it for you.  A do-it-yourself washer may set the pressure too high for the surface or hold the nozzle too close to it. This can result in chipped painting, damaged screens, and ruined siding. And though most power washing equipment you can rent has the same PSI as commercial-grade tools, it holds a minimal amount of water—making this project take days, not hours.

Do you remove moss from my roof?

We can, but it is not recommended to physically remove moss from your roof at the time of service, but in most cases a lot of the moss fall off once we apply our cleaning solution that breaks down their root structure. However, the good news is that our roof treatment neutralizes moss and lichens at their roots. This allows them to fall off the roof over time naturally, if not during our roof cleaning service.

What is involved in roof cleaning?

It is NEVER recommended to ‘power wash’ a roof. Therefore, we perform what is called a “roof treatment,” where we apply a specialized algaecide designed to eliminate moss, lichens, and black streaks. This is performed at a very low pressure to avoid structural damage, providing the best results possible for your home.

What are the dark black streaks on my roof?

The black streaks on your roof are an infestation known as Gloeocapsa Magma. This algae eats away at the limestone filler in your shingles, leaving behind a dark residue. Our roof treatment is designed to remove these black streaks and neutralize the infestation at its roots.

Does PowerWashCompany.com clean brick surfaces?

Yes, absolutely! We have a safe and effective process for cleaning brick surfaces.

What is house washing?

A house washing utilizes a soft wash process that combines safe pressure with biodegradable cleansers to remove dirt, mildew, algae, and other contaminants from your home’s exterior.

Will your house wash remove the “green stuff” from my siding?

Yes, it will. The “green stuff” you see on your siding is a form of algae that affects thousands of homes in Maryland each year. Our process is designed to safely eliminate not only algae from your siding, but also mold, dirt, grime, and other contaminants.

What happens if it rains on my day of service?

Our team works in the wind and rain. If the weather is too extreme, our technicians will reach out regarding rescheduling the service.

Do you use my water?

Yes, we do require access to a working water spigot on the outside of the house.

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.

What time will you arrive at my home?

It’s not possible to give you an accurate time of arrival. Each technician does several jobs a day, and each job is unique. This is why we do not require you to be home for our service. Feel free to go out and enjoy your day.

Do I need to be home for my services?

No. For your convenience, you do not need to be home. All we ask is that close your windows and doors on your service date and provide access to a working water spigot.

Does power washing increase the value of my property?

Yes, absolutely! Washing the exterior of your home can add up to $15,000 to the sale price, according to the National Association of Realtors.

Are your services safe for plants, animals, and the environment?

Yes, our cleansers are 100% biodegradable and our process is 100% eco-friendly.

How much does power washing cost?

Our services are priced based on several factors, such as square footage, the scope of service, and job materials being used. We provide quotes and schedule service all over the phone. No in-person estimates are needed.

How long does power washing take?

Each job is unique. The time it takes to complete is dependent on many factors, such as the size of the surface and the amount of buildup. Rest assured, our technicians will work on your property until they deliver the best results possible.

How are you getting my siding clean if you’re only using low pressure?

The key is in our heated wash combined with our detergent. We like to compare it to washing dishes. You wouldn’t want to wash your dishes in cold water, so why would you want to wash your siding in cold water? Bottom line – We don’t use high pressure blasting. Instead, we optimize the best results utilizing low pressure and heat combined with our cleaning detergent. It is the perfect cocktail for a SAFE exterior clean.

How often should I have my house washed?

We recommend having your house washed once per year. This provides consistent protection from harmful algae, mold, and other contaminants. Our Annual Maintenance Plan is designed as a convenient solution for homeowners to keep their home looking perfect.

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.

Can you clean my house or deck in the winter?

Yes, we operate all year long. Adjustable heating control of our cleaning water allows us to clean even in temperatures down to 35 degrees F.

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.

Isn’t mold a health problem?

Yes, Mold and mildew around your home create unhealthy conditions for those with allergies and asthma. Pressure washing will remove mold from siding, trim, and concrete surfaces.

What is the dark staining on my siding?

Most likely it is mold. All mold needs to grow is moisture (humidity) and a food source… and it will grow anywhere.

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 often should I clean my home?

Major vinyl siding manufacturers recommend a thorough cleaning every 12 to 24 months. Removing buildups of mold, algae and oxidation help keep your siding at its best.

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.

Is it safe to wash my house with heated water?

Our low pressure heated wash is warm enough to gain the advantages of heated water with no chance of damage to siding or plants. Unlike many contractors, we control the temperature of our water preventing it from getting too hot.

Why do you clean with heated water?

Heated water cleans more effectively than cold water. As the water temperature increases, so does the effectiveness of the cleaning solution.

Will pressurized water be forced behind my siding?

Unlike high pressure washing, our low pressure heated cleaning system uses pressure similar to a garden hose and will not be forced behind your siding.

Do I need to be at home?

Most customers are not at home when we clean their homes, but please remember to close all windows, clear your driveway, and put away fragile decorations.

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.
