"FANTASTIC AND FOLLOW UP! I highly recommend Treeium.
We used Treeium to renovate our kitchen. I got bids from 6 different companies and Treeium was neither the least nor the most expensive. But, Ron was able to show photos of previous work and also seemed the most sincere. We needed to have the kitchen finished in 5 weeks as we wanted it done before we moved into the house. Ron and his team finished the job on time and within the budget.
They've come over several times to make the smallest of adjustments for me. As a matter of fact, 4 months after the job, the kitchen faucet was loose and Ron sent someone to fix it and at no charge.
We plan on renovating our baths soon and Ron and Treeium will be the first team we call.

"I was happy to know that my satisfaction with the remodeled kitchen was the goal for the team at H.R.D., right down to the trim moulding under the cabinets. Both Antonio and Gio offered suggestions that proved to be more than just a nice ideas, but rather important design or function must haves .
Thank you H.R.D.

"Overall my experience with this company was great! The work that was done was really really good! Our contractor who assisted us was Jose. We added a living space and master bedroom to our home. The additions done look as if they were part of my house this whole time. Honestly it looks way better than I expected. The only reason I rated the company a 4.5 was because there was always some kind of miscommunication between our contractor and his workers. Don t get me wrong, things were always resolved, Jose was great at that. But my recommendation to is to make sure communication is #1. That way the customer is not confused or left wondering what will happen next. There was an issue with his floor guy though, he was rude and unprofessional. BUT the reason I am mentioning this is not to put down the company but let you know that we expressed concern for this issue and it was resolved professionally by Jose and it never became an issue again. The quality of work was top notch! His workers were all pretty cool guys and we always felt comfortable of who was coming into our home to do the work. I highly recommend this company for your next big project😊👍🏼 "

"RS Construction was wonderful. We used them to build our home which is about 3,267 square feet. It was a huge job but they did amazing work. We are so happy with every aspect of the house. They were so receptive to our ideas and were able to expand on them. They were also very affordable compared to the other companies we were considering. I highly recommend RS Construction whether you a remodeling or building an entirely new home like we did. I have no doubt this company can handle anything.

"Karl is a straight forward contractor - honest, answers your questions, gives examples, does some of the work himself, but has various subcontractors to handle the rest. Every crew was courteous, worked well together, and had great pricing when compared to other contractor's bids. The project turned out as planned and looks amazing."
