Professional, friendly staff. The services performed--clean/treat roof, wash exterior windows/screens and clean gutters--were done extremely well. I was pleasantly surprised to find they also cleaned off debris from my patio and asphalted areas. Much appreciated!
Great job! Did a big job for us having pressure washed ALOT of concrete, cleaned deck, railing and stairs, cleaned and treated roof, washed windows inside and out. Crew was outstanding! They seemed to be a cohesive team that enjoyed working with each other which showed in the work completed. Strongly recommend!
Juan, James, and Jacob did an amazing job on our house. It looks like new. Scheduling with Rachel was easy and communication was great.
Will definitely call them again the next time it's time to clean the outside of our house.
NW Prokleen cleaned my roof and gutters, their softwash method of cleaning was very gentle yet effective in removing and killing the moss we had on our roof. They also cleaned and resealed my driveway and it looks brand new again!

I’ve been getting my windows cleaned for a few years with NWProkleen. They pay attention to detail and take their time doing the work. They are the only company that have a poll long enough to clean our 3rd floor windows.

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.

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.
