SkySWC is Seattle's commercial window cleaning specialist, serving high-rise towers, mid-rise office buildings, and low-rise retail properties across King and Snohomish County. We are the only company in the Seattle area operating the proprietary HighRise™ remote-controlled window cleaning system — delivering streak-free results on every building, at every height.
Property managers, building owners, and facility directors trust SkySWC for scheduled maintenance contracts, post-construction cleans, and one-time services. Our crews are SPRAT-certified for rope access, OSHA-trained, and carry $8MM+ in commercial insurance coverage — with certificates of insurance available on request.
We provide ongoing maintenance contracts for high-rises, commercial buildings, hotels, and residential condominiums across King, Snohomish, and Pierce Counties. Our clients trust us because we show up, do the work right, and make their jobs easier.

We clean every commercial building type across the Seattle metro — from single-story storefronts to 40-story towers. Our approach, equipment, and access method are selected based on your building's specific height, facade configuration, and roof anchor availability.
Office towers, hotels, condos, and residential high-rises. We use our proprietary HighRise™ remote-controlled cleaning system and SPRAT-certified rope access for safe, streak-free results at any elevation

We invest in equipment that competitors simply do not have. Every tool we use is selected to deliver cleaner windows faster, with less risk to your building and our crews.
Request Custom QuoteSkySWC is the only company in Seattle operating the HighRise™ — a self-climbing, remotely operated window cleaning machine that cleans exterior glass, sills, and frames from the ground. It leaves no scaffolding, no swing stage, and no disruption to your tenants. Windows cleaned with the HighRise™ stay cleaner significantly longer than hand-cleaned glass
For low- and mid-rise applications, we use water-fed pole systems fed by purified, deionized water. Because purified water contains no minerals, it leaves absolutely no spots, streaks, or residue when it dries — no squeegee required.
For buildings with limited roof anchors, hard-to-access facades, or areas where mechanical equipment cannot reach, our SPRAT-certified technicians use industrial rope access techniques. This is the same methodology used for high-altitude construction and inspection — far safer and more cost-effective than scaffolding or boom lifts.
Depending on roof anchor configuration and building height, we also deploy traditional bosun chair and aerial lift systems — all operated by trained, OSHA-compliant crews.
Most of our commercial clients opt for ongoing maintenance contracts rather than one-time services. A scheduled program means your building always looks its best, and you are never scrambling to find a vendor before a property inspection, investor visit, or lease renewal.
We build custom maintenance schedules — monthly, quarterly, bi-annual, or annual — based on your building type, tenant mix, and budget. Contracts can be structured as either a capital improvement expense or an operating expense to suit your accounting needs.
Benefits of a SkySWC maintenance contract:

We have cleaned the Space Needle, Hyatt Regency, Lumen Field, T-Mobile, REI, Chihuly Garden and Glass, and dozens of Seattle's highest-profile commercial properties. Our work has been featured on KOMO News, KING 5, and KATU. When Seattle needs high-access window cleaning done right, SkySWC is the call.
All window cleaning work is performed in full compliance with OSHA and ANSI fall protection standards. We carry $1MM commercial auto, $2MM general liability, and $5MM umbrella coverage. All employees pass rigorous background checks, wear photo ID badges, and arrive in clearly marked SkySWC vehicles.
We provide detailed, written scope of work with every quote. No hidden charges, no surprise add-ons, and no rescheduling without notice. Our 4.9-star Google rating across 54 reviews reflects the consistency our clients experience on every service visit.
SkySWC is not just a window cleaning company. We offer trash chute cleaning, commercial dryer vent cleaning, pressure washing, gutter cleaning, building envelope maintenance, moss removal, and screen cleaning — all from one vendor, all to the same standard. Most property managers who start with windows add at least one additional service within the first year.
Whether you manage one building or a portfolio of properties, SkySWC makes commercial window cleaning simple. Contact us for a free, no-obligation site assessment and written proposal.
Commercial window cleaning pricing depends on several factors: building height, number of panes, frequency of service, interior vs. exterior scope, and the access method required. A single-story retail storefront will be priced very differently from a 30-story office tower. We provide detailed, itemized quotes at no charge — contact us for a free site assessment and we will turn around a proposal within 24 hours.
Most commercial buildings in Seattle benefit from at least two professional cleanings per year — once in spring following the rainy season and once in fall before it begins. High-traffic retail and hospitality properties typically schedule quarterly or monthly service. We will recommend a frequency based on your building's specific exposure, foot traffic, and appearance standards.
Yes. The majority of our commercial clients are on scheduled maintenance programs. We build custom contracts around your building's needs, structured either monthly, quarterly, bi-annually, or annually. Contracts include priority scheduling, locked-in pricing, and a single point of contact for your entire portfolio.
