Deck Building on Cape Cod, done the Fornalski way

Isometric illustration of deck building work on a Cape Cod home

A deck on the Cape works hard: sun, salt, sand, winter freeze and a summer's worth of family on top of it. We build for all of that, with solid framing, proper ledger flashing, and decking fastened clean so the surface stays smooth and safe for years.

New builds, rebuilds and repairs all get the same treatment. We replace tired boards and wobbly railings, rebuild rotted stairs, and design new decks around how you will actually use them, from morning coffee for two to a full crowd on the Fourth of July.

A deck on the Cape works harder than almost any room in the house, three seasons of sandy feet, salt air and family cookouts. We size the framing conservatively, fasten with coastal-grade hardware, and finish the railings like furniture, because a deck should feel as solid in year ten as it does on day one.

  • Deck rebuilds and resurfacing
  • Railings, balusters and gates

The team at Fornalski was great to work with. The communication was timely, estimate accurate / honored, & work was done on-time as promised. The task was removal & replacement of a new set of decking boards for a 2 step entry way. Everything was picked up & the job site was clean upon completion. Love the way everything came out. Will definitely call them again when the next need arises.

I can't say enough about Sérgio's business ethic and the quality he puts into his work !! He listens to the customer and makes suggestions about what he thinks would solve any issues !! Stand up man and company!! I had a vision for a deck for the lake..and kayak holder not even close to what Sergio envisioned ! Timely, very reasonable, and stands by his work. I received a recommendation from a good friend and have used Sergio since and given his name to neighbors and friends too

They demolished an outdoor shed and built a new shed. The new shed is wonderful. They cleaned up. The work was done on time and everyone was pleasant. I would highly recommend them and will use them for future projects.

Common questions

Should I choose composite or wood decking?
Composite costs more upfront and asks almost nothing afterward, wood costs less and rewards regular care. We walk you through both with samples in hand, and build either one the right way.
Can you repair my existing deck instead of replacing it?
Often, yes. If the frame is sound we can replace boards, railings or stairs and give the deck years of new life. If the structure is compromised we will show you exactly why before recommending a rebuild.
Do you build stairs and railings too?
Yes, including the tricky ones. Outdoor stairs and railings are finish carpentry with weather added, which is exactly the combination we like.
When is the best time to build a deck on the Cape?
We build most of the year. Booking in the off-season usually means your deck is ready the day summer starts instead of halfway through it.
Is your deck work licensed and insured?
Yes. Fornalski Construction is licensed and insured in Massachusetts, and decks get the same written scope, schedule and walkthrough as any other project we build.
