Customer Reviews

Jeffrey Heer

Read and his team were great to work with for home siding replacement. The work was high quality and on schedule, with excellent communication through the whole process. I would happily go with CNW again for future home construction work.

Jennifer Boelter

Read and his team remodeled our downstairs bathroom. Read got our bid and contract to us electronically soon after we first met to talk about the project. Read provided ideas about the best products to use and where to buy them and we had the big items on hand before the project started to prevent delay. He and his team are easy to communicate with, set clear expectations and timeline and do really quality work. They checked in with us about desired aesthetics throughout and made sure we understood the reasons for the technical decisions they made. This was a positive experience and we recommend Constant Northwest for your remodeling needs.

Wes Miller

We had a great experience with CNW finishing our basement rec room! Read was very helpful all the way from the proposal phase and on, giving us lots of options and pricing with the proposal that we were able to select from. Once they started the job, everything went smooth and everyone was very pleasant to work with. We'll definitely be working with CNW again on future projects!

Jane Majerus

We hired CNW for a sheetrock repair and had such a positive experience later called them back to help us with a total kitchen remodel. An amazing and talented crew; thoughtful, timely, solid construction, creative with building solutions, easy to work with, and always left the site tidy at the end of the day. Highly recommend!

Veronica Smith

Read and his team are fantastic—great to work with and deliver high quality work. They built a stair, added a new railing and water drainage system onto our deck in 2 weeks—just in time for our party where they got good use. Several folx have commented on the high quality of their work when seeing the deck. Highly recommend this company for deck projects!

Sandra Hundacker

I recently hired Read and his team for a home remodel, and the results exceeded my expectations. They expertly removed popcorn ceilings, installed luxury vinyl plank flooring, and transformed the staircase with beautiful stair treads and crisp white risers. They also completed a partial kitchen remodel, adding a gorgeous backsplash, butcher block countertops, and a modern sink. The project was topped off with fresh paint, new light fixtures, and curtain rods, perfectly bringing my vision to life. Despite encountering more significant challenges, like a cracked floor, Read managed the entire project smoothly and finished within the estimated time. He communicated thoroughly at each stage, kept me informed on progress and any updates, and honored our agreed-upon budget. I highly recommend Read and his team for any renovation needs—they’re skilled, reliable, and truly professional. I look forward to working with them again on future projects!
