DJZ Construction is a well renowned general contractor in Whatcom County. We are known for our dependability, quality, and communication. We specialize in residential additions, remodels, kitchen, bath and siding projects. We always stand behind our work, as customer satisfaction is our top priority.

I have been meaning to install railings on our front porch for many years now and especially as we, as well as our guests, get older. DJZ took our drawings and recreated the railing beyond our expectations. Very professional in their approach to working with us, and always kept a clean job site. The railings are beautiful, solid, secure and safe for anyone coming to the house. Thanks DJZ!! Without hesitation, we can highly recommend Derek and his crew for your construction needs.

I so love my new kitchen/great room. It’s my favorite place in my home and it’s where I spend most of my time. Derek was very easy to work with and has an eye for quality. He really understood what I wanted and did some very creative problem solving to get the results I imagined. Everyone who sees it lights up and says, “Wow, this is really beautiful. It’s so inviting and relaxing.” I will definitely hire him again and again.

We contacted DJZ Construction to help us build an addition onto our home. Over the course of the project from design to implementation, they held our hands the entire time and even worked with us to ensure the design looked fully integrated into our current home’s structure. Derek and TJ checked in almost every day during high touch points of the project and provided weekly updates to show progress and next steps in the pipeline. Derek’s input with overall design, TJ’s management expertise and dedication to perfection helped create a portion of our home that felt as if it has always existed since the day we purchased the home. Add on top a team of specialized contractors that have provided nothing but top tier craftsmanship and you have yourself a top quality experience. Once the project was complete, they continued to follow up to ensure no new items appeared since moving into the addition. This has been the most pleasant experience I have had with a contractor and I have recommended them to everyone who has asked for one. I have already lined up my next project with DJZ for next year and plan to continue to use them for the following set of projects as well.

We were nearing the end of a long remodeling project and needed a contractor to finish the last phase. A friend recommended DJZ Construction. From our first phone call to our last meeting Derek was clear and efficient. We looked at several construction options and were able to quickly and comfortably settle on the details. Throughout the project, Derek, TJ and everyone else involved kept us informed of times and progress. The work site was left clean and neat each day and only the most professional work was done. Upon completion, the entire project site, inside and out, was cleaned up and left as neat as before. We’ll be contacting DJZ for our next projects with complete confidence.

I want to say how satisfied we are with the new roof put on by DJZ Construction. They oversaw the entire job and delivered excellent satisfaction. I highly recommend them.

Derek Zender and his crew have worked on my home several times through our the years and I trust his workmanship. Recently I had my aluminium siding replaced with hardie plank and my home looks brand new! Their work is thorough, up to date, and they clean up every time. His company is professional, if there are any concerns he keeps me informed, and any changes are discussed in advance for my approval. I highly recommend them.
