Residential & Commercial
Professional window cleaning for homes, businesses, storefronts, and commercial buildings throughout Brewer, Bangor, Bar Harbor, Mount Desert Island, and surrounding areas of Penobscot and Hancock Counties.

Clean Views for Homes & Businesses
Proper cleaning improves visibility and protects window surfaces
Clean windows dramatically improve the appearance of a home or commercial property while allowing more natural light into interior spaces. Over time, glass surfaces collect dust, pollen, mineral deposits, and environmental contaminants that reduce clarity and leave streaks or haze.
Penobscot Cleaning Services provides professional interior window cleaning and exterior window washing for residential and commercial properties across Bangor, Brewer, Bar Harbor, and Mount Desert Island. Our technicians use professional squeegees, water-fed poles, and safe cleaning solutions to remove buildup and restore clear, streak-free glass.
Interior window cleaning is always available. Exterior window cleaning is quoted individually depending on building height, access requirements, and project scope.
Professional Window Care & Clear Results
Glass surfaces are constantly exposed to environmental debris including pollen, coastal salt, dirt, and rain residue—especially in coastal areas like Mount Desert Island and Bar Harbor. Without proper cleaning, these materials can leave stains or mineral spotting that reduces clarity and appearance.
Our technicians carefully evaluate the condition of each window and select the appropriate tools and cleaning methods. Professional equipment and proper technique allow us to safely remove buildup while protecting window seals, frames, and surrounding surfaces.
When to Schedule Window Cleaning
Many homes and businesses schedule professional window cleaning once or twice per year depending on environmental conditions and building exposure. Commercial storefronts and offices often benefit from more frequent cleaning to maintain a professional appearance.
Seasonal homes, vacation rentals, and coastal properties near Bar Harbor or Mount Desert Island may require additional service due to salt air and weather exposure that accelerates glass buildup.
