I had the recent pleasure of working with Radion. He renovated my deck by adding stairs and cleaning off the old and mildew. He was professional, responsive and he finished in the timeline that he said he would. I would recommend using him if you need any deck work!

•••••HIGH RECOMMEND •••• Radion did a terrific job. He didn’t take any shortcuts took his time and my porch looks great. The estimate$$$$ was definitely in my price range. Thank you Thumbtack for having a real skilled guy like Radion to represent you…. I have neighbors telling me how nice my porch looks.

Ninja Builders gets an A+++ from me! Mr R built an deck and stairs for me. His workmanship and attention to details is first class. Unlike the deck snd stairs that he replaced my deck and landing platform are bigger per my request. He was punctual, and finished within the time frame that we agreed on. I plan to hire him again in the Fall !!

We had an excellent experience with our deck project. From start to finish, the workmanship was outstanding, and the final result looks amazing. The structure feels solid, well-built, and exactly what we hoped for. He was professional, knowledgeable, and clearly takes pride in his craft. Now I’ll be honest—during the project, the backyard looked like a chef’s kitchen in the middle of dinner rush 😂 tools and materials everywhere! But that only showed how hard he was working, and the best part is he cleaned everything up beautifully once the job was done. If you want someone who delivers quality work, pays attention to detail, and leaves you with a finished product you can be proud of, I would absolutely recommend him.

Ninja Builders/Radion is amazing! Radion just did an incredible job on our porch. He was very responsive, listened to our concerns with our porch, he fixed everything that we needed, he was on time, and so friendly. The porch and paint job are unbelievably beautiful. We are so happy with job Radion did. Thank you so much!

My wife and I were absolutely beyond pleased with the custom deck Radeon and his colleague from Ninja Builders built for us. Their professionalism and work ethic working on the project was impressive. The level of detail and craftsmanship with the composite deck floor they installed and the privacy wall they built was excellent. Along with working from sun up to sun down, Radeon always communicated when they would be working and did a great job with cleaning up the work space after the deck was finished in two weeks as agreed. We are looking forward to enjoying our new space for years to come.

Ninja Builders did a fantastic job rebuilding our deck that was built completely wrong by another contractor. I appreciated his timely response and his flexibility with being able to start the next day. I had a house appraisal on Wednesday Aug 20th and NB was able to come out on the 16th and got it all done by the 19th. One day shy of our appraisal. I also appreciate his willingness to adjust his pricing to make it more affordable for us after having a bad experience previously. I do wish that he could have cleaned up below the deck a little better. There were a few debris left under there but my husband doesn’t mind getting that cleaned up. It would have been a lot easier to do before finishing the deck but overall we are grateful for a job well done!

We chose Radion from Ninja Builders out of three different estimates because he conducted himself very professionally and provided a thorough explanation of what would be included, ensuring it would meet all legal building codes. He also made it easy for us to understand that our old 23-year-old deck was not up to code. What I appreciated about Radion was that he was very prompt in all our communication: texts, phone calls, etc. Once we approved the job, he wanted to start the next day. We had to wait two days so we could clear off the deck and put things away for the season. Radion started two days later with his assistant and they got to work early in the morning and worked until it got dark outside. Radion’s addressing of every question or concern we may have had during the job left me impressed. We went with the raised posts so that we would comply with the HOA rules. Radion also did routing to the handrails, which gave it a pleasant look. He also added a third-stringer and cemented in the support 4x4 posts that give the stairs more support (which is code, but the old ones did not have this support). Radion’s work impressed two of our next-door neighbors so much that they wanted to get estimates for replacing their deck and stairs. As you can see in the photos, the deck and stairs look amazing. We wanted to use a more clear stain to have the beauty of the wood stand out. Sadly, our HOA required the uniform color that the rest of the complex has, as you can see after two coats of the approved stain were applied. Radion’s quality of work, promptness in putting in a full day on the job, and availability for every question or concern we may have had made us extremely satisfied. Anyone who has Radion of Ninja Builders do a job for them will be extremely happy and grateful to have had such a professional do their job! When someone does this quality work, I am very happy to give a glowing review because it’s difficult to find good contractors who care about the quality of work that they do! Once my brother and my brother-in-law saw the completed job they stated that they wished they had known about Ninja Builders before they had their decks completed this season. My brother had a large, complete deck done and my brother-in-law had replacement work done, both were both impressed with the quality of the work done. Thanks, Radion and your co-worker at Ninja Builders. I hope you have many years of success!

Amazing work. I'm so happy with the way the deck turned out. Radion and the team were some of the most hard working people I have ever met. They were on time, had great communication and listened to what we wanted. They gave great recommendations & they went above and beyond my expectations. I would 100% hire them for future projects that come along. A+ work. Thanks guys!! The deck is beautiful!
