We have used NWProKleen over the years — to clean our flat pvc roof, windows and to hang our holiday lights! Always so fast, friendly and we'll continue calling on them.

The ProKleen team has done our Christmas lights install for a number of years (and gutter cleaning at the same time). We have a high and steep roof and they have always done a great job. The team members are professional and nice to work with. We appreciate them!

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.

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!

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!

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 work! Workers were extremely friendly, cooperative and did a very nice job. Communication was great from start to finish. They stayed until everything was cleaned up as good or better than it was when they arrived. I would highly recommend this company to others.

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.
