Hire him!

I inherited a home that had been neglected for a long time.It is a sizezble house with a lot of weather exposure. NW Waterworks was the first step in a long series of projects. Mark is efficient, effective and conscientious. The results were amazing.

Great job!

We had Mark from Waterworks NW out to clean our concrete areas at our credit union. They did a very professional job and we would not hesitate to use them again. A+++

I also had Mark clean my windows at my home. Really high quality work and he uses a process I have not seen before with perfect results my windows have never been so clean.

Waterworks, works

I have used Waterworks and dealt with Mark the owner on several occasions. This company is one of the best mix of quality, value, customer care and professionalism that I have come across. And Mark and his staff genuinly care about your property and give you straight information. Plus, they are responsive, not making you wait around or book your service at some date way in the future. Again, just a straight shooter. I would recommend Mark and his company to anyone.

Great Job

Our shake roof was in need of cleaning along with repairs, requiring entire new cap line and the replacement of several bundles of shakes. We chose Waterworks NW because we felt confident that owner, Mark Poole knew and understood the work that needed to be done. He was businesslike and professional, answered honestly the questions and concerns we had regarding the present condition of our roof and it's future longevity. They were punctual on the scheduled date, worked diligently and efficiently and took care in their cleanup. We were extremely happy with their work and without hesitation would use them in the future.
