Their communication skills were excellent as was their service. Cleaned and treated my roof, cleaned the gutters and cleaned the windows. Cleaned up afterwards. Will have them back when needed.

5.0 Heather M. Seattle, WA

The company's communication with clients is top rated. You are notified of every step and time. The personnel who worked on my home were on time, courteous, thorough and very professional. I will recommend them to everyone. Highly-qualified and high-quality work.


They were very thorough and very nice. Job was well done.

Initially, we received a quote from this company about a month back. When the tech was scheduled to come out, he was hours late, when he was scheduled to arrive between 10:30-11:30. I received a text that he was en route at 12:39, when he hadn't shown up 2 hours later, my husband and I decided to take the pups to the park up the street. When we were getting ready to pull up in the driveway at 3:30, I received a call from the tech that he was there and no one was home. I let my husband deal with the estimate and went inside. When I scheduled the service, the tech was scheduled to arrive between 8:00-8:30. When I hadn't heard from him by 9:00, I messaged the number for the business and received no response. Around 11:30, I finally received a message saying that he was en route for him to arrive around 12:30. Once he arrived, rather than knocking on the door and introducing himself, he called, and said he was getting on the roof, from there - he used a leaf blower to blow out the gutters and the roof, and gave no warning that he would be blowing debris all over the place so that I and the lawn care professionals both got pelted with debris while I was discussing services with them. As we had scheduled him for 8:00-8:30, he shouldn't have even been there at that point. There is still moss on the roof, and he left debris all over the yard and front porch and deck which my lawn guys ended up taking care of for me. He was here for less than an hour, used a leaf blower and no other tools to clean the gutters and roof, which my husband could have done for free, and was 4 hours late with no notification and no apology which impacted another service care providers ability to do their job, as I had scheduled them to come out during different times purposely. After, when I went to pay - he was only able to take cash and to pay with card, I was to wait on an invoice. Which I didn't receive until yesterday, but as I hadn't taken the time to pay it, as I obviously had some questions on what the service should have entailed, they have sent a second invoice, less than 24 hours after the first. So as far as customer service, quality, value, responsiveness, and timeliness, its really a 0/5 stars, but obviously google wont let you leave 0 star reviews. Wont be using the company again and am definitely going to be sharing this review on all other sites that they are listed.

I would like to thank John for his excellent work cleaning the roof, gutters, and downspouts

5.0 Casey C. Kirkland, WA

They were very responsive and communicated well when getting an estimate. Hired to treat and remove moss from the roof, clean the roof, and clean out gutters. Juan and James did a great job - they arrived on time and completed everything in the estimated time frame. It looks great!

5.0 Charlene G. Seattle, WA

HIred to clean and treat moss on roof, clean gutters ,siding and the huge amount of concrete around the house. Juan and Josh did a phenomenal job. Due to the large amount of work it took all day but the house and property look great. They cleaned up after they were done. Very pleasant and hard workers. John who arrived to give the bid on my very tall house with a very steep roof was prompt, professional and transparent. Would hire again and again.

5.0 Michele M. Kirkland, WA

I never knew my roof and gutters could look so clean! To be honest, my gutters look brand new. From hiring to paying the process was seamless. The staff was professional and friendly. I plan on going to N.W. Prokleen for all my future roof and gutter cleanings.


Very friendly and professional. The crew spent a lot of time gently cleaning a very mossy roof and gutters and cleaning up the surroundings after. A good value--we would hire them again.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
