Has a window in your Roslyn Harbor house stopped cranking shut, or does the door to your terrace grind along its track? That kind of trouble rarely means the whole unit is finished. Usually one part has worn out. We check it first. When that part can be fixed, we fix it and leave the rest of the house alone.

A swing-out window stuck half open, a slider that grinds, a sill gone soft on the harbor side? On a Roslyn Harbor property, a repair is often the smart first call.

If your casements and sliders are original
A lot of Roslyn Harbor houses come from the 1950s and 1960s. A house from those years may still have its first casement windows, the kind that swing out when you turn a crank. It may also have a big picture window and a sliding door to the lawn.

After so many seasons, these parts give out first:
- The crank gears strip, so the window spins but will not pull tight.
- The seal around double glass fails, and a haze forms between the panes.
- The small wheels under a slider flatten, and the door drags or jumps.
Harbor wind, salt and your windows
The village describes rolling hills and views of Hempstead Harbor, and many houses have water views. If yours does, wind and salt may reach that side first. Hinges can stiffen, locks can pit, and paint on the sills may break down sooner.
Once a year, open and lock every window on the harbor side. A sill that feels soft under your thumb deserves a call. We can cut out only the rotted wood and rebuild it to match.
If your property is an acre or more
Many lots here run one to two acres. If your house is a big one, it may have dozens of windows and several outside doors. You do not have to fix them all in one season.
Start with the ones you use most, or the ones that let in drafts. We can work through the rest over time. Fixed, each window holds on to its first charm, and it looks better once the work is done.
What the village says about windows
Roslyn Harbor lists the work that needs a building permit. Putting in new windows, or replacing existing ones, is on that list unless it is an exact replacement. The village says swapping a window or door for the same size and type, in the same opening, usually needs no permit. That changes if you replace half or more of your windows.
Roslyn Harbor wants a call to its Building Department before work begins: (516) 621-0368, at 500 Motts Cove Road South. Only the village can say what your project needs. Repairing the windows you already have may keep things simpler, but ask before you assume.

Learn moreQuestions from Roslyn Harbor homeowners
Can you come on a Saturday to fix my windows?
Plan for a weekday. The village building page lists construction hours as Monday to Friday, 8 to 5. It allows no work on weekends or federal holidays.
My casement window spins but will not close. Is it broken for good?
Probably not. Crank gears grind away with use. We can put in a new operator (the crank and its arm) and the window should close tight again.
Our back door faces the harbor and the lock is hard to turn. What causes that?
Salt and damp air can corrode a lock from the inside. Sometimes cleaning and lubricating brings it back. If the parts are worn, we can replace the lock or hinges.
Is a permit needed to repair windows in Roslyn Harbor?
Phone the Building Department, (516) 621-0368, and ask. The village says a same-size swap in the same opening usually needs no permit, unless you replace half or more of your windows. That ruling belongs to the village, not to us.
Will you also come to Roslyn, Old Brookville or East Hills?
Yes. Those three neighbors of Roslyn Harbor are part of our service area too.
