Greenport Construction is one of the Bay Area's premiere remodeling, landscaping, and custom millwork service for both businesses and consumers. Owners and brothers, Jacob and Eli Froneberger established the business in 2012 with the vision to help customers create their dream homes and businesses, all while having a strong focus on sustainability and personalization to each client's project.

The team brings years of construction, woodworking and landscaping experience to the table. Whether your taste is rustic or refined, Greenport Construction can make your vision a reality. My husband and I were looking to redesign our new home. A friend of his told us about Greenport Construction and I am glad we decided to try them out.

They came to the house on time, offered us advice on the best way to make the house better. The workers were hardworking and very knowledgeable, and the design looks awesome. Our home looks wonderful. I am so impressed with this company. I asked Greenport Designs to bid on moving a bathroom.

We're two brothers, Jacob and Eli Froneberger, who grew up in wonderful Marin County where we still reside and call home. Growing up amongst such gorgeous surroundings inspired us to create more beauty in the world ourselves. We both loved working with our hands and had a good eye for design and style.
At Greenport Construction, some of our best work starts before the building even begins. We are dedicated to offering solutions to your functionality issues, creating modern and upgrade style options, and make dreams come true. We believe in sustainability within our designs, so we opt to source from FSC certified retailers and offer our customers green options for everything from kitchen cabinets to custom made furnitures.
Greenport Construction offers sustainable solutions for your landscaping dreams. Our staff is certified and trained by Green String Sustainable Agriculture Institute including an extensive knowledge of landscaping and hardscaping. Our patio and deck designs offer our clients a modern and exclusive outdoor escape.

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

I had a fence/ gate that I wanted built and I was super nervous about it and no idea who I should call . 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

Ok... I won't be surprised if The property Brothers copied these guys! Eli and his brother own the place and they're a dream come true team!

Eli helped me with a last min artsy wood project and I can't recommend him enough. Smart, perfectionist, reliable, knowledgeable, responsive, efficient and super kind.

I had a small job which was to repair the leg of a chair that had broken off. I made many phone calls, but everyone I spoke to could care less or would even return my phone call. Until I called Eli at Greenport Designs!! Eli was so courteous and polite and was willing to take a look at my chair and see if it could be repaired. He always answer the phone and was prompt in getting back to me on the status of the chair. Not only did he do a great job of repairing the leg, but Eli personally delivered the chair to my home in just a few days. Eli couldn't have been nicer and more helpful!

I cannot thank Greenport enough for helping me create the space of my dreams. When I came to Eli and Jay in early 2016, I was discouraged by my family's opinion of building open shelving throughout my kitchen. I wanted a wrap around top shelf and my family disagreed, saying it would close off the space. Eli and Jay met my concerns with a logical approach, further creating a vision I could never see for myself. Their enthusiasm for my project fed into every facet of my home and before I knew it I had three custom shelf units made of walnut for my kitchen, a beautiful pine bar-type desk, and
