New Castle Construction did an incredible job….. The work was high quality and completed on time within budget. We have had numerous positive remarks on the project and many friends and neighbors that have since used Jason for their projects. It would be difficult to find an individual or company that could match Jason’s talent and abilities in the construction business.

Jason was very professional and knew exactly what he was talking about when it comes to decking. He and DJ were diligent and hard working. Would definitely hire again!

Deck Job

We absolutely love our new deck and French doors! We were amazed at how quickly Jason was able to finish the project without compromising the quality of work.

Jason brings a level of respect to the project and the homeowner that is uncommon. It is what you expect but rarely receive. As the project unfolded, we made the inevitable changes which were met with open acceptance and pricing was always fair.

I do lots of on-line research. I read every review of the 4 companies that I received quotes. I was very impressed with The New Castle Building Group. The owner was more knowledgeable than the other 3. I had read your Trex website.

Jason is professional, detail-oriented, reliable and trustworthy! We have thoroughly enjoyed our basement since New Castle finished it…and much of that is due to Jason’s guidance during the project. Additionally, the tile work and woodwork he did are beautiful and are highlights of our basement. We always call Jason for our home repairs and upgrades now and are always happy to recommend him to friends!!

New Castle went beyond my expectations when it came to designing and remolding our master bathroom. We trusted his opinions and now it’s my favorite room to show off.

Great job and it looks awesome! Jason also added a roof to our deck, and it blends in nicely with the rest of the home.
