A Streak-Free Shine for Interior, Exterior & Skylights


The appearance of your windows is important from both the outside and the inside. It’s what your visitors see as they are entering your home and what you see when you look out to the beautiful PNW. You don’t want to see stains from bird poop and water streaks.

At DAPrDAN, we are excited to be at your service to get your windows sparkling once again! We clean your interior and exterior windows — along with skylights. We appreciate that there is a certain amount of trust involved when you let someone into your home. That’s why each of our staff is uniformed, respectful, and polite, and we background check all our employees at least once a year. We treat your home exactly as we would our own and take all of the necessary steps to ensure it stays as we found it.

We also offer commercial window cleaning (up to three stories), as well as storefront cleaning too! First impressions count and we’re excited to help your business shine.

Would you like your windows to be streak-free and sparkling? Get in touch with us today! 


What your neighbor in Bothell, WA says:

These guys are amazing, did a great job and went above and beyond, We had our windows cleaned inside and out, and pressure washed all outdoor surfaces. They did it with a smile, on time and on budget. You can’t ask for anything more. I highly recommend them to anyone who wants a superior job done.

Gutter Services Protect Your Home


Your gutters do a great job in protecting your home. Don’t let leaves, dirt, and other unnecessary critters cause unneeded expenses and stress. And don’t risk the danger of getting up there on a ladder to try to clean your gutters yourself — please believe us when we say, the risk is never worth it.

At DAPrDAN, we thoroughly clean your gutter system. Our team of techs is experienced in getting up high on a ladder to remove all of those little things that can cause big problems. Depending on the service you require, we utilize various roof washing techniques such as power washing and soft washing. Whichever process we use, we ensure that it is gentle on your home, removes those unnecessary stains, and improves your home's aesthetics.


What your neighbor in Kirkland, WA says:

The crew from DAPrDAN were our Saints from Heaven! We have a high roof that needed the moss and algae cleaned off, as well as the gutters and windows cleaned. We can’t believe the difference! Everyone was working together and enjoying themselves like a Disney movie. What an incredible company you have! We are signing up for regular services from DAPrDAN and will recommend to friends.
— Jay & Suzy S., Kirkland, WA


Remove Algae, Mold, Mildew and Other Stains with Low-Pressure, Gentle Brightening


Are you tired of looking at your home and seeing that green stuff on your siding? Miss that gorgeous color it once had? Whilst borrowing your neighbor's pressure washer might seem like a potential solution, we would advise that you hold your horses until you read a little further. When it comes to house washing, you would not apply the same amount of pressure to your home’s vinyl siding as you would your driveway. If you do apply the wrong amount of pressure, you could actually blow a hole right in your home’s siding — not a mistake you want to make for the sake of saving a few bucks.

Here at DAPrDAN, we have been cleaning Northwest homes since 1998. The application of our gentle, effective method of cleaning your home siding goes far beyond simply looking good. We eliminate the nutrient base for all algae, mold, mildew, moss, and lichen while disinfecting your home’s exterior for any harmful, penetrating bacteria. As an additional service, DAPrDAN also provides an antimicrobial finishing spray that comes with a 3-year no-algae guarantee.

If you would like to feel proud of your home exterior when you pull up on your driveway, get in touch with us today!


What your neighbor in Bellevue, WA says:

Do a great job every time. Prices are reasonable and the quality is above average! I wouldn’t use anyone else.

Roof Cleaning, Restoration & Preservation


Are you concerned with preserving the integrity of your roof? Do you want to extend the life of your roof, getting the most value out of it as possible? Our moderate, yet damp climate provides a host of challenges for northwest homeowners who desire to keep a healthy, safe and attractive looking roof.

DAPrDAN provides exceptional cleaning, restoration and preservation services for metal roofs, cedar shingle roofs, composite/asphalt roofs and ceramic tile roofs. Depending on the level of service you select, we can provide you with either a 1-year, or 3-year guarantee that your roof will be free of moss, lichen, algae, mold, fungus and harmful bacteria.


What your neighbor in Issaquah, WA says:

We have used DAPrDAN to clean and treat our roof and gutters on several occasions and have always been very pleased with the results. Our recent service was provided by two congenial and professional technicians who arrived on time, worked diligently, removed all fallen debris, and left our roof and landscaping around the house looking better than ever! DAPrDAN will even return in 6 weeks to check on the moss treatment. I highly recommend their services.
— Claudia M., Bellevue, WA


Clean Decks & Porches Look Great & Prevent Nasty Slip & Fall Injuries


Is there green algae beginning to grow on your front porch steps? When wet, the entry of your home, or back deck can become as slick as an ice rink. While you could get on your knees and scrub the surface aglae away for a season, it won’t be long before it’s back in force, with moss soon to follow.

DAPrDAN can instantly reduce the risk of slip and fall injuries and improve the overall appearance of your home with our proven 3-step deck cleaning process. It attacks algae at the micro-level and then removes all traces of organic life from the tiny crevasses of wood and composite decking. This process leaves you with longer lasting and better looking results.


What your neighbor in Camano Island, WA says:

Crew showed up on time and did an excellent job. Initially they walked me through how everything would be done. They worked safely when high up on ladders or working on the roof. They were careful moving around the inside and outside of the house. They did an excellent job cleaning up all of the crusty material removed from the gutters. We have used them for several years and will continue to do so. Excellent service at a reasonable cost.
— Heinz R., Camano Island, WA


A Clean Driveway is the Red Carpet to Your Castle


Your driveway is what connects your home to the rest of the world. When you return home from work, or invite guests over for dinner, your driveway is the red carpet leading to your castle. If that red carpet has turned green with moss, or algae, DAPrDAN can bring it back to a like-new appearance. In many cases we can lift old stains from oil and rust, and brighten the concrete. You even have the option to upgrade your service to include protective and aesthetic sealing of your concrete and/or asphalt driveway.

DAPrDAN keeps your driveway clean of moss and debris, looking fantastic and safe for all your family and friends.

A Clean Fence Makes You a Good Neighbor


Peering through your windows to the world outside, your fence stands guard, keeping strangers out and loved ones in. It’s the structure that designates property lines and the place you call home. If your wood fence is left to the elements, its classic look can quickly turn to disrepair. The combination of UV rays and dust can make your fence look old, where as our wet northwest climate can produce slimy-looking stains that darken from mold and algae. But, with DAPrDAN just around the corner, there’s no need to worry. We can restore the look of your fence and, in turn, raise the overall aesthetic value of your property.


What your neighbor in Snoqualmie, WA says:

These gentlemen were respectful and thorough. I was able to customize my cleaning and window washing into a package that met my needs, was competitively priced and both were done in an extremely timely manner. Highly recommend!
— Jay Lynn C., Snoqualmie, WA


Clean & Seal Specialty Stone Walkways & Patios


Is moss becoming an unwelcome guest at the entry walkway of your home? Is algae flanking you on the left walkway to the back patio. If left to its own devices, moss and algae will take over your home creating slick walkways, patios and steps. DAPrDAN keeps your walkways safe and beautiful with our 3-step cleaning process. Upgrade your service to include sealing your walkways and patios and enjoy even more protection and beauty.


What your neighbor in Snohomish, WA says:

Clean Solar Panels Can Achieve Up To 30% More Energy Efficiency


At their 1.6 million-watt solar farm in Mountain View, CA, Google conducted a groundbreaking experiment. They discovered that “the number one method to maximize energy produced by solar panels is to clean them.” They found that “cleaning solar panels that had been in operation for 15 months doubled their output (of electricity)”. They also reported that “professional cleaning of solar panels produced 12% higher output compared to those cleaned by rain.”

Here at DAPrDAN, we’re fanatical about doing things the right way. Not only will we clean your solar panels with deionized water for a spot-free shine, but we’ll apply a protective solution to your solar panels that will help to prevent premature soiling and stains. Depending on the level of service you choose (and your panels), we’ll treat the roof surface under your panels for moss, algae, lichen, mold, mildew and harmful bacteria.


What your neighbor in Mill Creek, WA says:

A positive recommendation here for DAPrDAN home services. Meeting with Greg first to discuss all things we were looking to have done. Very professional and knowledgeable about products they use and services were scheduled soon after first contact. All services were completed in a timely manner and I was very happy with end results. The two technicians were delightful, took their work seriously and yet seemed to enjoy the tasks they performed. When work was completed we did a walk around outside and I was able to see all they had done. Outstanding.
— Christina E., Mill Creek, WA

Great job... love how clean my house is now. I’m also happy that we’re on a plan and are taking care of the roof to last a long time.
— Charlene W., Camano Island, WA


Affordable, budget-friendly plans to keep your home smiling.


When home maintenance tasks get put off (due to high cost, for example), they can mutate into wallet-eating monsters called “restoration projects”. This is when a relatively inexpensive task like gutter cleaning, leads to water intrusion into the walls of the home, causing dry rot and pest invasion. A $200 gutter cleaning can quickly become a $25,000 renovation.

At DAPrDAN, we make maintaining your home a no-brainer. Check out what we can do for only $99/month

  • Blow loose debris from roof surface (2x per year)

  • Clean all gutters & downspouts (2x per year)

  • Clean all exterior windows (2x per year)

PLUS… choose from 1 of the following 3 options:

  • OPTION 1: Clean exterior siding (1x per year)

  • OPTION 2: Clean interior windows (2x per year)

  • OPTION 3: Apply anti-moss treatment to roof (1x per year)
