What Our Customers Are Saying
ProKleen is a great company to work with. The owner John has high integregity, does personal home visits to help build a plan and his employees are kind and delightful. We have used ProKleen for holiday light installations a few times now. We are happy with their recent installation and recommend them to others. I personally value that their team is consultative and will share ideas and recommendations and work within your budget.

Really appreciated the polite and efficient young man who was in charge of our project. Also the original estimator came to our home to be sure all was well with the two services of gutter cleaning and roof de-mossed. You get what you pay for!

John sent a team, headed by Sean, to clean roof, patio, and windows. They did a great job and the place is all spiffed up. There were a few small things that were not quite to our satisfaction: they were super responsive and came back the next day to make it right. Excellent service, great work ethic.

From the estimate to the work done everyone at NW Prokleen was exceptional. We were presented with several very clear and concise options for the work on our house. They were able to perform the work on our house the day after we were given the estimate due to a cancellation. The crew that came to work on the house arrived early and started work immediately. They finished the work faster than expected and did a fantastic job. We didn't know our house could look so clean!! We would recommend NW Prokleen to anyone looking for a job well done at a reasonable price. We will definitely be using them again in the future!The GuinnsKenmore WA

We were very pleased with the services provided by this company. John gave a fair estimate of cost and scheduled the work. Roger and Eli arrived the following week to remove needles (plus small patches of moss) from our roof and soft wash our patio, stone surfaces and driveway. From beginning to end, all were courteous, knowledgeable, professional and efficient. We look forward to working with this company in the future.

We had NW ProKleen come by to powerwash and stain our fence recently. They were very professional and thorough completing the project. James, who's a great guy, supervised and helped with the powerwash and then single-handedly stained the fence. He and did an outstanding job as did his crew. We've been getting compliments every since and are likely to have James to refinish our deck next year. I've attached some pictures of the project.

James and Gavin arrived on time, set up their equipment, and began working right away. They were both friendly and courteous. They asked permission before moving things, and then helped me to put things back where I wanted them. They worked well as a team and did what I had requested and more. They worked steadily and efficiently. Highly recommended.

Prompt quote, reasonable price, amazing and communicative crew, professional, good value. Had our roof cleaned and fence pressure washed. Was vet impressed by the card the crew took to work around our precious plants, including vines growing on our fence.Final scheduling notice was via text and the time they selected worked great for us, but it would have been nice to get a call to schedule so we could confirm the time also worked for us in advance.Will definitely use ProKleen in the future!

John and his team cleaned our gutters and put up our Christmas lights. They were willing to go the extra mile by using some of our own lights to do trees on our property, in addition to matching their lights on our house (non led, which is hard to find). They were reasonable and professional. I highly recommend NW Prokleen!

Excellent service from beginning to end. Always responds to my requests within a timely manner. Prices are good and the quality is worth more than what it is charged. I prefer to support local businesses vs coroporations where you are just another number. We've been working with John and his crew for a few years and he treats us like family.

Is Your Roof Dirty?
Has dirt and mold on your roof finally become an embarrassment? Our soft wash method has been proven to safely clean and extend the life of shingles. With the use of a balanced method of lower pressure, proper products, and allowing cleaning solutions the time they need to clean, soft washing eliminates the problem instead of merely spraying at high pressures for an initial surface fix. In comparison to our competitors, our incorporation of biodegradable and phosphate-free solution sanitizes, penetrates bacteria, and eradicates the root cause to produce a long-lasting, deep clean result. When combined with the use of a lower psi and implementing a concentrated wash time, NW ProKleen is the most trusted provider to thoroughly clean surfaces safely and effectively.
