Window Washing - Our professional team are highly skilled and fully licensed and insured.  Specializing in cleaning windows for high rise and commercial buildings, Northwest Window Maintenance has previously been entrusted to maintain the sparkling appearance of some of Seattle's most iconic buildings such as the Space Needle, the Edgewater Hotel and the 'W' hotel.

You can expect the same level of commitment and service whether you are a commercial customer, or residential customer.

Gutter Cleaning - For many of our residential customers, gutter cleaning is an extremely important aspect of home maintenance. Failure to keep gutters clean can cause clogs in the downspot and gutter, which can in turn lead to leaks into your home.

Not everyone wants to climb up on a slippery roof, or scale a ladder, so let our fully insured team handle this task for you, and we can also collect and dispose of any leaves in your garden for you.

Pressure Washing - Mold and spores are one of the most common causes of deterioration in the home, and mold can substantially reduce the lifespan of shingles on a roof.

Our team can pressure wash the siding on your home, your deck, driveways, sidewalks and curb areas.  Not only will this help preserve the condition of your home, it can also help maintain it's beauty.

For any of these services, simply contact one of our representatives using the contact information below and we'll be happy to help you.
