Commercial Exterior Cleaning in Downtown Seattle

At Deep Water Pressure Washing, we take pride in delivering exceptional exterior cleaning services throughout Seattle, Washington. Our recent commercial cleaning project at Hanoki in downtown Seattle was a true test of skill, teamwork, and dedication. This job required a combination of patio cleaning, concrete cleaning, siding cleaning, and window cleaning—all while ensuring minimal disruption to the residents of this high-traffic building.

Project Overview

The project took place in downtown Seattle and involved cleaning the patios, exterior windows, siding, and concrete walkways of the Hanoki building. This was no ordinary task, as our team had to carefully maneuver pressure washing hoses up nearly seven stories, running them 300 feet across the length of the building.

To ensure a thorough but safe cleaning process, we used a surface cleaner at a low-pressure setting, protecting the materials from damage. The exterior windows were cleaned using a pure water system, leaving them spotless and streak-free. For the building’s siding, we applied a three-part, water-based solution at low pressure to effectively remove dust, grime, and organic buildup while preserving the integrity of the surface.

Challenges & Approach

High-Traffic Residential Area

One of the main challenges of this project was working in a high-traffic residential building. With many residents coming and going, we needed to ensure that our cleaning process did not disrupt daily activities. To address this, we placed absorbent cloths on door seals to prevent water from entering the units.

Equipment Maneuverability

Another challenge was maneuvering our equipment at such a height. Running hoses seven stories high and across 300 feet required strength and coordination. Our team had to be extremely careful while working along the exterior handrails of the patios, ensuring that every surface was thoroughly cleaned. Additionally, we stationed a crew member at ground level to monitor runoff and ensure that no residents were affected by the cleaning process.

Protection of Metal Fixtures

Using the wrong cleaning products could lead to rusting or damage, so we implemented a chemical-free cleaning process to ensure the railings and other metal surfaces remained in pristine condition.

Surface-Friendly Cleaning Techniques

To achieve the best results, we followed a surface-friendly cleaning technique, using a low-pressure surface cleaner to protect the concrete, patios, and siding from damage. For the windows, our pure water filtration system ensured a streak-free finish, and we took extra care to clean window seals, screens, and doors, leaving the entire exterior looking refreshed and renewed.

Results & Client Satisfaction

The transformation was remarkable. The patios, concrete walkways, and siding looked revitalized, and the windows were crystal-clear, free of fingerprints and streaks. Residents were extremely pleased with the results, with many expressing their satisfaction and even requesting that we return more frequently for routine cleaning.

Our ability to complete the project efficiently while maintaining high-quality results left a lasting impression on both the building management and the residents.
