I am Ray Sanwald and this is my business and passion.  I'm a 7th generation Shelter Islander and am very proud to be a local. I only use local help and would love to work with you to build or improve your home.  Give me a call and I will come right over to help plan your vision.  ​




Every old house, can use a facelift.  Adding new siding, windows and trim can really make a difference.

It doesn't matter what style of house you have.  We are prepared to ensure that we match the way your house was

Multi level deck with blind fastening.  Cedar, mohogany or epay hardwood.  We can do it all.


"I worked with Ray for two years in the event industry where reliability and commitment to excellence when others around you are screaming is the name of the game. Ray won each and every time. Dependable. Smart. Creative. You can't do better."

Christine Merser, Owner, Water Mill Party

“From the planning stage through completion Ray seemed to take what could have been an otherwise overwhelming project and guided me through the process. I found the entire team very helpful. It is apparent that they take tremendous pride in their work. The detail with the finished carpentry really pulled things together and I feel the end result is a beautiful new sliding glass door and upgraded deck that greatly improved my home."

Kevin, Shelter Island, NY

“I've used Ray and his team to replace the trim on the back of my 27 year old house.  What an amazing job!  He was personally here working every day, which you don't see alot of anymore.”
