What's in the way in a cape basement
The basement under a cape is big and open, until you look up.
-
A low main beam
The main beam runs down the middle of the basement and sits lower than the rest of the ceiling.
We box it in with sheetrock and trim so it looks like it belongs.
-
Ducts and pipes everywhere
Heating ducts and water lines hang below the joists in no particular order.
We plan the ceiling height around the lowest runs and box the rest.
-
Posts in the middle of the room
Lally columns (the steel posts that hold up the main beam) land right where you'd put a couch.
We wrap them, or plan walls and rooms around them.
-
A narrow stairway
Steep, tight basement stairs with a bare railing.
New treads, trim, railing and paint so the stairs match the finished room.

Cape basements in Blue Point
A lot of Blue Point homes are capes, and many capes have a full basement under the whole house. In a smaller home, that basement can be the biggest open space you have. The catch is what runs through it. There’s usually a main beam down the middle, held up by steel posts, with heating ducts and water pipes hanging below the ceiling joists. Finishing the space well means planning around all of that instead of pretending it isn’t there.
Keeping your ceiling height
Height is the first thing we measure. We check under the joists, under the beam, and under the lowest duct or pipe, because each part of the room can be different. Where there’s room, a drop ceiling gives easy access to shutoffs and cleanouts. Where it’s tight, we box in the beam or a run of ductwork with sheetrock and leave the rest of the ceiling as high as it can go. A mix of the two is common in cape basements.
Working with the posts
The steel posts under the main beam aren’t going anywhere. They hold up the house. What we can do is make them part of the design. Some people like them wrapped in wood and trim so they look like finished columns. Others would rather we frame a wall right on the post line so the room divides naturally, with a family room on one side and an office or storage room on the other.
Don’t forget the stairs
Cape basement stairs tend to be steep and narrow, with plain treads and a pipe or two-by-four for a railing. They’re the first thing you see on the way down, so we finish them with the room: new treads, trim along the sides, a proper railing and paint.
Floors and walls below grade
Basement floors are concrete slabs, and they can feel cold and a little damp. We usually suggest vinyl plank, which is waterproof and goes right over the slab. For the walls, we frame a small gap off the foundation so air can move, then hang sheetrock and finish it smooth. Before we cover anything, we look for signs of water. If there is a leak, it needs to be fixed first, and we will tell you what we see.
Close to home
Blue Point is one of our home-base towns, between Patchogue and Bayport on the bay. Before any work starts, you get a written, itemized price that lists the framing, sheetrock, ceiling, floor and trim, with a start date and how long the job will take. We clean up every day and finish with a walk-through.

Blue Point basement questions
Do I need a permit to finish my basement in Blue Point?
Usually, yes, especially if you're adding a bedroom or changing plumbing or wiring. Blue Point is in the Town of Brookhaven, so check with the Town of Brookhaven building department.
My basement ceiling is low. Can it still be finished?
In most cape basements, yes. We measure the height under the joists, the beam and the ducts, then pick a ceiling that keeps as much room as possible. Sometimes that means sheetrock in one area and a drop ceiling in another.
Can you hide the steel posts?
We can wrap them in wood and trim so they look like finished columns, or place a wall right on the post line so it disappears into the layout. They have to stay, since they hold up the house.
How much does it cost to finish a cape basement?
It depends on the size, how much boxing and framing the obstacles need, and the ceiling and floor you choose. We measure and give you a written, itemized price before we start.
