Wood Window and Door Repair
Wooden windows are one of the most beautiful — and most demanding — features in a Long Island home. When they're working correctly, they add character, insulation, and charm that no vinyl window can match. When they're not, they let in cold air, moisture, and noise, and they get worse fast if ignored.

What Our Wood Window Repair Service Covers
Wood windows develop problems in predictable ways. Long Island's humid summers, freezing winters, and salt air near the coast accelerate every one of them. Here is what our technicians repair every day:
Rotted Wood Frames and Sills
Wood rot is the most common issue we see on Long Island. It starts at the bottom corners of frames and sills where water collects, and it spreads fast once it starts. Soft, spongy, or discolored wood around your window frame is an early sign. We remove the damaged wood, treat the area, rebuild the profile using epoxy filler or Dutchman repair, and seal it against future moisture intrusion. In most cases, rotten window repair is completed in a single visit without replacing the entire frame.
Swollen or Warped Frames
Wood expands when it absorbs moisture. In Long Island summers, frames that were fine in March can be completely stuck by July. We plane and adjust swollen frames so your windows open and close smoothly again. We also identify and seal the moisture entry point so the problem doesn't return next season.
Broken or Damaged Sash
The sash is the part of the window that holds the glass and moves up and down (double-hung) or swings open (casement). Cracked, broken, or painted-shut sashes are one of the most common calls we get from homeowners in Nassau and Suffolk County. We repair or replace the sash while preserving your original window frame and glass where possible.
Deteriorated Glazing Compound
The putty that holds glass into wooden frames — called glazing compound — dries out, cracks, and falls away over time. When it does, cold air comes in around the glass, condensation forms, and the glass itself becomes loose. Our window reglazing service restores the seal between glass and frame, improving both energy efficiency and the appearance of the window.
Drafts and Air Leaks
If you can feel cold air coming through a closed window, the seals have failed. On wood windows this is typically caused by failed glazing compound, shrunken wood pulling away from the frame, or deteriorated weatherstripping. We locate every air pathway and seal it properly. Many customers tell us their heating bills drop noticeably after we complete this work.
Peeling or Failing Paint
Paint on wood windows is not cosmetic — it's the primary moisture barrier. When paint peels, bare wood is exposed to rain and humidity. We strip failing paint, treat any early-stage rot or moisture damage we find underneath, prime the wood properly, and repaint. This stops a cosmetic problem from becoming a structural one.
Broken Hardware and Mechanisms
Locks, lifts, pulleys, balances, and hinges all wear out on wood windows over time. We carry a wide range of replacement hardware for all major window brands and can restore smooth, secure operation to windows that haven't worked properly in years.

Should You Repair or Replace Your Wood Windows?
This is the question almost every Long Island homeowner asks us. The honest answer: repair is almost always the better choice for wood windows, especially in older homes. Here's why:
When replacement makes more sense — if more than 60% of the frame is structurally compromised by rot, if the sash cannot be salvaged, or if the window is a non-original replacement already, we'll tell you honestly. We have no interest in selling you repair work that won't hold.
- Cost — full window replacement typically costs way more than professional wood window repair (depending on the scope of work).
- Quality — older wood windows, particularly in pre-1980 Long Island homes, were made from old-growth timber that is denser, harder, and more rot-resistant than anything available today. Replacing them with modern windows often means trading down in quality.
- Historic homes — many homes in areas like Manhasset, Old Westbury, Garden City, and the Hamptons are in historic districts or carry deed restrictions that require preservation of original windows. Repair is often the only permitted option.
- Energy efficiency — properly maintained and resealed wood window with window recaulking and new weatherstripping can match the insulation performance of a modern double-pane replacement window.
When replacement makes more sense — if more than 60% of the frame is structurally compromised by rot, if the sash cannot be salvaged, or if the window is a non-original replacement already, we'll tell you honestly. We have no interest in selling you repair work that won't hold.

THE MOST POPULAR QUESTIONS
How much does wood window repair cost in Long Island?
The cost depends on what needs to be done. We provide free written estimates on-site before any work begins, so there are no surprises.
How long does wood window repair take?
Most repairs are completed in a single visit of 1–4 hours per window. Larger jobs — such as extensive rot repair on multiple windows — may require two visits, particularly if materials need to cure between steps. We'll give you an honest timeline at the estimate stage.
Can you repair windows in historic homes?
Yes. We have significant experience working on historic properties throughout Long Island, including homes in designated historic districts in Garden City, Oyster Bay, Sag Harbor, and the Hamptons. Our historic window restoration service is specifically designed for homes where original windows must be preserved.
My wood windows are original to the house — is it worth repairing them?
Almost certainly yes. Original wood windows in Long Island homes built before 1970 were typically made from old-growth Douglas fir, white oak, or similar dense hardwoods. These species are no longer commercially available at the same quality. Repairing and maintaining original windows preserves both the character and the structural quality of your home.
Do you repair Andersen, Pella, and Marvin wood windows?
Yes — these are among the most common brands we work with. See our dedicated pages for Andersen window repair, Pella window repair, and Marvin window repair for brand-specific information.
Do you offer emergency wood window repair?
Yes. If a window has been broken, compromised by a storm, or poses a security risk, call us at 516-908-8005 and we'll prioritize your appointment.
