We had a very small project, however, I was nervous about all it would entail to fix the problem. Eli and his team were attentive to my concerns. They offered an array of options and always kept my budget top of mind. Everyone was a pleasure to work with. They were able to fit me in right away and even finished the project early!

I could not possibly recommend a custom design/carpentry business more than these guys. I just finished my fourth project with them. They have built out three of our closets, a custom desk, a full bathroom and now a beautiful new dining table. The first project we did with them was building out new closets with bars, shelves and drawers. We came to Eli and Jacob with designs that we got from California closets. The first and most impressive thing was that they made a suggestion that got us twice as much hanging space with the same amount of drawers. Having someone who actually pays attention

I asked Greenport Designs to bid on moving a bathroom. The bid itself was good in terms of amount, but what impressed me most was the careful way it was broken down between each section of the job for both materials and labour. I knew exactly what I was paying for and what I was getting I ended up not moving the bathroom but repairing the old one, a smaller job and one they finished perfectly. Each step was done thoroughly and neatly and the whole job was finished a day earlier than originally quoted. Even more surprising was the response of my tenant who complains every time I let a repair

Well I was referred to Greenport thru a friend and I could not be happier with the work they did ., a gentleman by the name of Duane came over gave me an estimate and some suggestions regarding the fence and it turned out gorgeous!! Thank you Duane for making this a pleasant experience, done on time and the price was right ! Thank you thank you
