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.

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 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 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 clean brick surfaces?

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

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.

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.
