Dormer & Second Floor Additions in Long Island
When you can't build out, build up. Dormers reshape unused attic space into fully functional rooms, and a full second-floor addition gives you an entirely new level for bedrooms, bathrooms, offices, or guest suites. These projects take precise structural planning, which is exactly why our in-house design team engineers every one before we pick up a hammer.
Our specialty since 1999

Reviews
What customers say about our dormers & second floors
"My husband and I are first-time homeowners and were looking to add a second-floor addition to our new home. After meeting with several contractors, our gut told us that Vinnie was the perfect person for the job. Our gut was right! Vinnie is very passionate about what he does, and always offered the best solutions for us to make our vision into a reality. We highly recommend them!"
"Our project was to dormer out an upstairs bedroom in a mid-century cape. After obtaining several estimates, we called Fine Finish Construction. The cost for the project was very reasonable. Their workers were courteous and skilled, everything was done up to code. In the end we have a great new room. I would highly recommend Fine Finish to anyone considering a construction project."
"Met with many contractors and decided to go with Fine Finish for a major home renovation. Chopped off and rebuilt the entire 2nd floor and updated the first floor. Their price was very fair for the amount of work they did. It is hard to find somebody who stands by their work, and Fine Finish certainly stands by theirs!"

Dormers & Second Floors FAQs
What's the difference between a dormer and a second-floor addition?
A dormer extends out from your existing roof to create headroom and usable space in the attic. A second-floor addition removes the roof and builds a complete new story. We'll help you decide which fits your home and budget.
Is my house strong enough for a second floor?
Our design team evaluates your foundation and structure first. If reinforcement is needed, it's built into the plan and the quote.
What happens if it rains while the roof is off?
We plan the work to keep the open roof as short as possible and protect the house from the weather throughout.
