SkySWC provides a full suite of commercial building maintenance services. Whether you manage a high-rise condominium, a hotel, a mixed-use tower, or a historic property — we have the equipment, certifications, and experience to keep every part of your exterior in top condition.

Our crews are trained and equipped for every height and access challenge Seattle's buildings present. We use the HighRise™ self-climbing window cleaning system — the only one in the Pacific Northwest — delivering exterior cleaning at scale, in a fraction of the time traditional methods require. We also service low-rise storefronts, office buildings, and retail properties.
Dirty trash chutes breed bacteria, attract pests, spread odors through your building's hallways, and create fire risk from grease and debris buildup. Our 3-step process — presoaking with industrial degreasers, steam washing with disinfectant, and enzyme deodorizing — eliminates buildup completely and keeps your building compliant with health and safety standards.
We serve apartment buildings, condominiums, mixed-use towers, and commercial properties throughout Seattle and Bellevue.
Clogged dryer vents are the leading cause of commercial laundry room fires. We provide professional dryer vent cleaning for multi-unit residential buildings, hotels, extended stay properties, and commercial laundry facilities across Seattle — ensuring your systems meet NFPA 96 fire safety standards and operate at peak energy efficiency.
Commercial pressure washing for parking garages, building facades, sidewalks, dumpster zones, loading docks, and awnings. Our parking garage service includes water capture systems to meet Washington State stormwater and environmental compliance requirements — something most pressure washing companies in Seattle are not equipped to offer.
Some maintenance jobs require more than a ladder or a lift. Our SPRAT-certified rope access technicians can reach any part of your building's exterior — safely and efficiently — for cleaning, inspection, caulking, sealant application, anchor point installation, and more. We take on the high-access work that other companies turn down.
We repair and maintain the exterior envelope of commercial buildings throughout Seattle — including brick and concrete repair, terra cotta, caulking, window sealing, balcony decks, and siding. Regular envelope maintenance prevents water intrusion and extends the life of your building's exterior by decades.

We provide detailed, itemized written proposals before any work begins. Most of our clients operate on recurring maintenance contracts — because consistent maintenance is more cost-effective than reactive repair, and because property managers need vendors who show up as promised, every time.
SkySWC carries comprehensive coverage for all commercial building maintenance operations:
Certificates of insurance (COI) are available on request and can be issued in any format required by your building's management, ownership, or legal team.
The company knows how important it is for the commercial buildings to keep the windows professionally clean and intact. That is why, they use the most advanced gear for this purpose. We perform the cleaning with the self-climbing HighRise™ window cleaning system, which leaves no scratches and not only thoroughly cleans the frames and windows, but also the entire building to extend iims life.
Our company has chosen this self-contained machine due to a number of benefits it provides to the customers. After all, this is the most important thing we pursue. The work is starting from the top of the building and saves months of window cleaning work allowing us to perform all the necessary cleaning tasks in a single day. Our technicians are experienced in its remote control operation. This helps customers save a lot of money too and have perfectly cleaned windows. Moreover, the windows cleaned by Skyscraper Window Cleaning with HighRise™ machine /the only one in Seattle WA/ stay cleaner much longer compared to those that are cleaned by hand.
Skyscraper Window Cleaning never uses chemicals in the process of high-rise cleaning knowing that they might damage the windows. We use only pure water.
Whether you manage one property or a full portfolio, SkySWC can build a maintenance plan that keeps your building clean, safe, and compliant — year-round. Request a free site assessment today. No pressure. No commitment.
