About Summit Window Cleaning
Summit Window Cleaning was founded by Dana Brancucci, whose background in art and design continues to shape how the company approaches every project. What began as a hands-on pursuit has evolved into a detail-focused operation built around craftsmanship, not shortcuts.
Dana’s perspective is simple. Clean glass is not just about removing dirt. It is about restoring clarity, light, and the way a space feels. That mindset has led Summit to specialize in high-end post-installation window cleaning, where precision matters and mistakes are not easily corrected.
The company operates differently by design. Technicians are not brought in casually. They are trained through a structured process that includes weeks of shadowing, internal curriculum, and OSHA-level safety standards. The goal is consistency, not variability.
Today, Summit continues to grow through referrals and repeat clients who value reliability and attention to detail. The focus has never been on volume. It has always been on doing the work the right way.

Window Cleaning
Window cleaning is where precision shows. Using reverse osmosis and deionization systems, Summit produces spot-free results without residue or streaking. Combined with carbon fiber poles that reach up to 90 feet, even complex properties are handled safely and thoroughly, leaving glass clear and consistent from every angle.

Solar Panel Cleaning
Dirty panels reduce energy output more than most homeowners realize. Summit uses controlled cleaning methods, including robotic systems when appropriate, to remove buildup without damaging sensitive surfaces. The result is improved performance and a system that operates as intended.

Gutter Cleaning
Gutters are often overlooked until problems appear. Proper cleaning restores water flow, prevents overflow, and protects siding, roofing, and foundations from avoidable damage. The focus is on function, not just clearing debris.
Gutter Cleaning
Pressure Washing
Exterior surfaces gradually lose their original appearance due to buildup and environmental exposure. Pressure washing is used carefully to restore these surfaces, improving curb appeal while preserving the integrity of the material beneath.

professional window cleaners near me for high windows
Dana did an amazing job on our windows! I thought some were open at times they were so clean. Our tracks were extremely dirty as I don’t think we had ever cleaned them. They looked fantastic after he was done. Very respectful, kind, diligent worker. I’d recommend him to anyone!

Frequently Asked Window Cleaning Questions
How is pricing determined?
Pricing is based on a combination of factors, including the number of windows, accessibility, height, and the level of buildup present on the glass and frames. Homes with large architectural glass, multi-story access points, or post-construction residue require a different level of time and precision than standard maintenance cleaning. The goal is to provide a quote that reflects the actual scope of work so there are no surprises once the job begins.
Do I need to be home during the service?
In many cases, you do not need to be home, especially for exterior-only cleanings. As long as access to the property is clearly arranged ahead of time, the work can be completed without interruption to your schedule. For interior cleaning, it depends on access and preferences, but the process is always communicated in advance so everything is handled smoothly.
Is your process safe for all types of windows?
Yes. Different glass types and installations require different approaches, and that is taken into account before any work begins. Whether it is standard residential glass, high-end post-installation windows, or delicate finishes, the cleaning method is adjusted to protect the surface while still achieving a consistent, clear result. The use of purified water systems also reduces the need for harsh chemicals.
What makes your cleaning different from others?
The difference comes down to process and consistency. Instead of relying on basic tools or inconsistent techniques, Summit uses reverse osmosis and deionization systems to remove impurities that cause spotting. Technicians are trained through a structured process, not just handed equipment and sent out. That combination leads to results that are more uniform, longer lasting, and noticeably cleaner.
How often should windows be cleaned?
For most homes, one to two cleanings per year is a common baseline. However, properties exposed to more dust, pollen, or construction activity may benefit from more frequent service. The goal is not just to improve appearance in the moment, but to prevent buildup that becomes harder to remove over time and can affect clarity.
Do you clean high or hard-to-reach windows?
Yes. Summit uses carbon fiber water-fed poles that can safely reach up to 90 feet from the ground. This allows for thorough cleaning of upper-level windows without relying on ladders in areas where they may be unsafe or impractical. It also improves consistency since the same controlled method can be applied across the entire property.
Will there be streaks after cleaning?
No. Traditional streaking is usually caused by minerals left behind in tap water or inconsistent drying methods. The purified water system used by Summit removes those minerals entirely, allowing the glass to dry naturally without residue. This creates a uniform finish that holds up longer than standard cleaning methods.
Do you offer recurring service plans?
Yes. Many clients choose to set up recurring cleanings to maintain a consistent level of clarity throughout the year. This not only keeps the property looking its best but also reduces the effort required for each visit since buildup never has a chance to accumulate. Scheduling is flexible and can be adjusted based on seasonal needs or property conditions.
