Roof Soft Washing

Roof soft washing is the process of removing green algae, gloeocapsa (black algae), mold, mildew, lichen and moss from roofs. Roof washing can also clean oxidation on metal roofs. Roof soft washing can extend the duration of a roof's ability to function. Algae and other types of build-up often form on the north and west parts of roofs that are shaded or receive less sun, and can reduce a roof's life expectancy. The presence of soot, dirt, or biomass can affect how much sunlight is absorbed by a roof and thus the amount of heat a building absorbs.

​

Because algae and moss retain moisture, they can cause shingles to deteriorate and rot. Mold, mildew, algae, and fungi growths are frequently excluded under most standard insurance coverage policies. Insurance companies consider keeping the roof clear of debris as being part of normal building maintenance, and that means they can deny a claim for damage caused by organic debris on roofs under the grounds of negligence on the part of the property owner. 

Exterior Soft Washing

Soft washing can clean years of mildew, dirt, and algae from your building’s exterior. Low pressure washing is safe for stucco, concrete, aluminum, steel, wood, and brick. It is recommended to perform building soft washing every few years for general maintenance, as well as to prepare an exterior for painting.

Fence Cleaning & Sealing

Typical power washing can strip wood fencing and damage the wood. Soft washing is safe for wood, vinyl, and metal fencing. Along with soft washing, PSI also offers de-oxidation of metal fence hardware, as well as wood fence sealing.

If you have recently installed a new wood fence, make sure you protect your new investment by sealing it. New wood fences should be sealed within1-2 weeks after installation. PSI only uses premium Clear Wood Sealer which enhances and maintains the wood's natural color, and provides long-lasting, durable protection for 2 years.

Deck & Patio Cleaning

Deck cleaning maintains your deck's functionality. Moss, mold, black algae, and green algae build-up not only looks unsightly, but can also cause damage to the structure of your deck and reduce the life of your deck. Soft washing is safe on all deck surfaces; including wood and composite decking.

In addition to maintenance cleaning, soft washing should also be completed in order to prepare your deck prior to any staining, sealing, or painting. PSI also offers wood deck sealing. If you have recently installed a new wood deck, make sure you protect your new investment by sealing it. New wood decks should be sealed within1-2 weeks after installation. PSI only uses premium Clear Wood Sealer which enhances and maintains the wood's natural color, and provides long-lasting, durable protection for 2 years.

Gutter Cleaning & Brightening

Gutters are designed to collect rainwater from the roof and carry it away from the foundation of the home through downspouts.  A routine cleaning of your gutters can prevent damage to your roof, exterior and foundation, saving you thousands in possible repair costs.

Window Washing

Cleaning windows can be a tedious task, as well as dangerous when windows are above a first floor level. It is recommended that windows are cleaned regularly to prevent glass degradation and improve your building's heating efficiency. Build up on windows can reflect the sun's UV rays, stealing away free heating. Dirt particles and allergen build-up on window screens and sills can also diminish your property's air quality and increase your exposure to allergens.

Concrete Cleaning & Oil Stain Removal

Winter weather and debris can leave stains on concrete. When debris sits for long periods of time on concrete, organic materials will start to break down and weaken the concrete's surface, leading to chipping and pitting. Concrete should be cleaned once or twice a year to increase its lifespan. High pressure power washing should not be used on concrete because it can degrade the concrete's surface and cause irreversible damage.

Exterior Cleaning

Routine cleaning removes germs and dirt from surfaces, and lowers the risk of spreading illnesses. Soft washing detergents clean and disinfect exterior surfaces such as playground equipment, dumpsters, and dumpster bays.
