About Window Cleaning Companies in Seattle

Dirty windows can take your home's curb appeal down several notches and prevent mood-boosting sunlight from making its way inside. You can probably wipe off handprints and the occasional smudge from your windows, but window cleaning is not just about removing dirt and grime from the interior side of your windows. The outside of your windows matter too!

However, once you add in the height of second-story windows, the potential for fungal growth on the exterior of the frames, and additional exterior cleaning services you may need, it is time to consult a professional window cleaning company.

Many window cleaning companies offer other home exterior cleaning services. Contact a professional to complete your window cleaning services, and ask about the other services they offer, such as pressure washing, gutter cleaning, or roof cleaning.

Residential Window Cleaning in Seattle

Window cleaning services

Window cleaning companies typically wash windows either by hand, with a water-fed pole cleaning rig, or a combination of the two. You'll also see the window cleaners use a variety of tools, depending on the height of the window and how dirty the window is.

You'll likely see your window cleaning team using a combination of the following tools and equipment:

  • Soap and water
  • Brushes
  • Steel wool
  • Razor blades
  • Squeegees
  • Lint-free towels
  • Ladders

Always ask the company you hire whether their service includes removing and wiping down window screens. Cleaning the window screens with soap and water typically involves an extra charge.

Any issues with the windows or seals should be noted and brought to your attention. Cleaning window tracks and sills are not always part of a standard window cleaning job, so be sure to clarify those details before work begins. If the company does not clean window tracks and sills, a house cleaning company will. Paint and sticker removal and the use of green cleaning products may come at an additional charge.

Hiring a window cleaning company in Seattle

There are a few guidelines you should stick to so that your project goes smoothly. Make sure your contractor is licensed and insured so that you're not liable if one of the window cleaners is injured or damages your home.

Also keep an eye out for window cleaning companies with membership in the International Window Cleaning Association (IWCA). The IWCA promotes safety standards, education for window cleaners, and research in the field. A company with a connection to the IWCA will be up to date on current best practices.

Regular cleaning can protect your windows from scratches and damage. A good guideline is to have your windows and home exterior cleaned twice a year. Get multiple estimates, and ask about the products and equipment the teams use. If eco-friendly products are important to you, speak up! Many companies offer this option.
