35+ Years of Commercial Exterior Cleaning
Commercial
Power
Washing
Professional exterior cleaning for buildings of all sizes. We safely remove pollutants, biological growth, carbon staining, and embedded contaminants that accelerate facade deterioration.
Professional Exterior Cleaning
Buildings of All Sizes. Every Surface Type.
For over 35 years, Interstate Contracting and Restoration has provided professional commercial power washing services across the tri-state area.
Our crews understand that facade cleaning is not simple. Left untreated, biological growth and embedded contaminants cause long-term material degradation and increase restoration costs.
Cleaning Chemistry & Technical Expertise
The Right Chemistry for Every Surface
Different substrates require different cleaning solutions. High pressure alone can destroy masonry and EIFS.
PROSOCO Cleaners
Trusted restoration and maintenance cleaners matched to brick, block, precast, stone, EIFS, and stucco conditions.
Dumond Chemicals
Environmentally responsible coating and contaminant removal products for heavy oxidation and legacy paint systems.
Substrate Matching
We match pressure, chemistry, dwell time, and rinse methods to the exact surface conditions on site.
Surfaces We Clean
Extensive Surface Expertise
Our team has hands-on experience across every major commercial exterior substrate.
Brick & Block Masonry
Low-pressure hot water with substrate-matched detergents protects mortar joints and brick faces.
Precast Concrete
Hot water extraction and restoration cleaners remove carbon deposits, efflorescence, and traffic film.
Natural Stone
Marble, granite, and limestone receive pH-appropriate cleaners and controlled pressure.
EIFS / Stucco
Low-pressure, low-chemical-concentration cleaning protects delicate finish coats.
Metal Panels
Targeted chemistry addresses oxidation, rust bloom, and industrial fallout.
Painted Surfaces
Biocidal pre-treatments and low-pressure rinse cycles protect coatings while removing growth.
