A•N•S•I Pittsburgh Services
Regular maintenance exterior and interior window cleaning for commercial buildings, including apartments and condominiums, real estate, healthcare, hospitality, retail, and more. If required, we also offer a deeper clean to remove tougher debris.
Safety is our top priority. We provide industry-leading internal safety training to our window cleaners and implement the newest and safest practices. We use our tenure, deep knowledge, and the support of our operations team to successfully access hard-to-reach areas and complete large and unique, intricate projects.
Over time, the condition of windows deteriorates for a variety of reasons. This includes pre-cast run-off, deposits from irrigation sprinklers, acid rain, and metal oxidation that cannot be removed from standard maintenance window cleaning services.
We have developed a proprietary method to remove these window conditions that does not carry the same risks as methods deployed by other providers that utilize abrasive chemicals that can damage windows. This service includes safe restoration for window seals, building facades, and landscaping.
Post-construction window cleaning removes caulk, adhesive, and debris before turnover to restore your windows and facades to look new again after a renovation or remodeling project. We understand that construction sites have hard deadlines and can work with you to get the job done promptly and on schedule while knowing how to navigate a construction site safely.
High dusting is used to clean hard-to-reach areas such as pipes, beams, and rafters. For example, common areas that need high dusting include school gyms, fitness centers, restaurants, manufacturing, industrial plants, and interior atriums.
We are experts in hard-to-reach areas that janitorial cannot access. We use our knowledge and tenure in the industry to determine a solution for areas that are difficult to access.
Metal mullions are the vertical bars used on doors and windows to divide them into smaller panes. Mullions are a challenge to clean and polish. However, if not cleaned regularly, the metal can pit and start to oxidize, requiring costly replacements. Metal mullion cleaning is a process that cleans and shines these metal bars, making them look new again. We can provide a comprehensive maintenance plan to restore your mullions and prevent future damage.
We offer high-pressure, heated, and non-heated pressure washing to safely and efficiently clean concrete walks, driveways, loading docks, retaining walls, decks, garage floors and walls, and other exterior features. Appropriate precautions are taken with brick, natural and synthetic stone, and other special finishes. We also take special care to protect the surrounding area before work begins.
