Your commercial property makes a statement before anyone walks through the door. Algae streaks, mildew buildup, grimy windows, and neglected building exteriors communicate the wrong message to clients, tenants, and visitors. A Plus Exterior Cleaning delivers professional commercial cleaning services throughout Maine and New Hampshire — from Portland and Scarborough to North Conway and Wolfeboro — using safe, effective soft washing techniques that remove organic growth without damaging your building's exterior surfaces. Unlike high-pressure washing methods that can strip paint, damage siding, and force water into vulnerable areas, soft washing relies on low-pressure application combined with professional-grade cleaning solutions to eliminate algae, mildew, and biological growth at the source. The result is a thorough, lasting clean that keeps your property looking sharp longer. Whether you manage a commercial building, retail space, multi-unit property, or professional office, A Plus Exterior Cleaning brings the same quality-first approach to every job. Every service begins with a free in-person estimate so you know exactly what's involved and what to expect — no surprises, no shortcuts.

A Plus Exterior Cleaning offers a comprehensive range of commercial cleaning services tailored to the unique demands of commercial properties across Maine and Southern New Hampshire. **Building Soft Washing:** Removes algae, mildew, and biological growth from commercial building exteriors using low-pressure application that protects siding, paint, and finishes. Ideal for retail buildings, office complexes, and multi-unit properties. **Commercial Window Cleaning:** Streak-free, spot-free window cleaning that enhances curb appeal and maximizes natural light inside your building. Clean windows signal professionalism and attention to detail to every person who approaches your property. ** Permanent Lighting Installations :** Upgrade your commercial property's exterior with professionally installed permanent LED lighting. Fully app-controlled, color-changing systems that can be customized for any season, holiday, or branding event — eliminating the recurring cost of seasonal install and takedown each year. ** Gutter Cleaning :** Clogged commercial gutters lead to water overflow, foundation damage, and costly repairs. Thorough removal of leaves, debris, and buildup keeps your drainage system functioning properly year-round. All services are available individually or as bundled packages — ask about discount pricing when you combine multiple services for your commercial property.

There's a significant difference between a company that treats a surface and one that actually cleans it properly. A Plus Exterior Cleaning doesn't cut corners or rush the process. Before any commercial cleaning begins, the property is assessed in person to identify the type and extent of biological growth, any surface sensitivities, and the safest, most effective approach for the specific building materials involved. Soft washing is the preferred method for commercial building exteriors because it eliminates the risk of damage that high-pressure washing carries. The cleaning solutions applied are designed to kill algae, mildew, and other organic growth at the root level, not just blast it off the surface temporarily. This means your building stays cleaner for longer between service visits, giving you better value over time. For commercial window cleaning, the goal is a completely streak-free and spot-free finish — the kind that makes a noticeable difference in how your building presents itself from the street. For permanent lighting installations , every fixture is professionally mounted with durable materials rated for outdoor commercial use, and the entire system is controllable from a single app, giving your property manager flexibility to update colors and themes without any additional service calls.

A Plus Exterior Cleaning provides commercial cleaning services across a wide service area spanning Maine and New Hampshire. In Maine, that includes Portland, South Portland, Westbrook, Scarborough, Falmouth, Cape Elizabeth, Yarmouth, Biddeford, Saco, Kennebunk, Wells, Kittery, and the greater Sebago Lake region including Naples, Raymond, and Fryeburg. In New Hampshire, commercial properties in North Conway, Conway, Bartlett, Jackson, Wolfeboro, Ossipee, Tamworth, Madison, Freedom, Alton Bay, and the Winnipesaukee area are all within the service footprint. This region is characterized by heavy seasonal moisture, dense tree cover, and the kind of humid summers that accelerate algae and moss growth on building exteriors. Commercial properties in downtown Portland contend with urban grime and salt air, while properties further inland near the White Mountains and lake regions face persistent organic growth from surrounding foliage and humidity. A Plus Exterior Cleaning's approach is specifically suited to these conditions, delivering exterior cleaning results that stand up to the local environment. Available Monday through Saturday, 9am to 7pm. Payment accepted via Cash, Check, or Venmo.

Many exterior cleaning companies grow quickly and sacrifice the detail work that actually matters. A Plus Exterior Cleaning was built on a different philosophy: stay focused, take on the right clients, and deliver excellent results every single time. That commitment is reflected in a consistent record of 5-star reviews on both Google and Facebook across hundreds of completed projects. Every commercial cleaning engagement is approached as if the property belongs to the team doing the work. That means careful attention to surrounding landscaping, building materials, and any property-specific concerns you raise during the estimate. You'll be educated on what needs to be done and why — not sold services you don't need — so that the decisions you make about your property are informed ones. If you're managing a commercial property in Maine or New Hampshire and you're ready to work with a team that genuinely prioritizes quality and accountability, A Plus Exterior Cleaning is available to assess your property and put together a plan that fits your needs. Bundle discounts are available for properties requiring multiple services, making it practical to address several maintenance items in a single engagement.

Managing a commercial property means making decisions that protect both the building's appearance and its long-term value. Neglecting exterior maintenance doesn't just look bad — it accelerates surface degradation, creates slip hazards, and can lead to expensive structural repairs down the road. Routine commercial cleaning is one of the most cost-effective investments a property manager or business owner can make. A Plus Exterior Cleaning takes a quality-over-quantity approach that sets the work apart from larger, higher-volume companies. Because the team remains intentionally smaller, every commercial property receives thorough, focused attention from start to finish. You won't be rushed through as part of a long job queue. The process begins with an in-person free estimate at your property — not a phone guess — so the scope of work is clearly understood before a single drop of solution is applied. From the coastal humidity of Cape Elizabeth and Kennebunk to the wooded, moisture-heavy climate of the Lakes Region and White Mountain foothills around Conway and Ossipee, commercial buildings in this region face consistent challenges from moss, algae, and mildew. A Plus Exterior Cleaning understands these local conditions and brings the right solutions to address them effectively, giving your property results that last.
