Exterior
Window Installation & Replacement in Nassau County
We are not just installers. We understand framing, waterproofing, and exterior systems — so your window actually performs long term, not just looks good when we leave.
Window Services We Offer
Full Window Replacement
Pull old units, reframe when needed, seal everything properly. Done so it looks like it was always part of the house.
New Construction Windows
Window installation for additions, dormers, and new builds — framed and sealed correctly from the start.
Reframing & Structural Work
We understand framing. We can open up, resize, or reconfigure openings before the window goes in — not just work within an existing rough opening.
Waterproofing & Sealing
Proper flashing, sealing, and moisture barriers so the window performs long term — not just looks good when we leave.
Egress Windows
Code-compliant egress window installation for basements and bedrooms, properly sized and sealed.
Custom & High-End Windows
We source accordingly — budget-driven or fully custom. We work with Crystal Windows as a primary line but we are not locked into one brand.
Why Titan for Windows?
Most of what we do is full replacements — pulling old units, reframing when needed, sealing everything properly, and making it look like it was always part of the house. That is not how everyone does it.
We work with Crystal Windows as a primary line, but we are not locked into one brand. If the job calls for higher-end custom or budget-driven, we source it accordingly. The right window depends on the house, the opening, and what the homeowner actually needs.
The big thing that separates us: we understand framing, waterproofing, and exterior systems. We are not just dropping a window in an existing opening and caulking around the edges. We address the rough opening, flash it correctly, and seal the full exterior system. That is the difference between a window that performs for 20 years and one that causes moisture issues inside your wall two winters from now.

Window FAQ
Do you offer free window replacement estimates in Nassau County?
Yes, Titan Project Solutions offers free estimates for window replacement and new construction windows throughout Nassau County and Long Island. Call or text (516) 557-4933 to schedule a walkthrough.
What brands of windows do you install?
We work with Crystal Windows as our primary line. If the job calls for something higher-end, custom, or budget-driven, we source accordingly. We are not locked into one brand — the right product depends on the project.
What is the difference between your installation and a big-box store install?
We are not just installers. We understand framing, waterproofing, and exterior systems. Most basic installers drop a window in the existing opening and caulk around it. We address the rough opening, reframe when needed, flash it properly, and seal the full exterior system so the window performs long term.
How long does window replacement take?
Most full-house window replacements on a standard Nassau County home take 1 to 3 days depending on the number of windows, any reframing needed, and exterior finish work. We do not leave your house open overnight.
Do you handle permits for window replacement in Nassau County?
Permit requirements for window replacement vary by municipality and scope. For basic in-kind replacements, permits are often not required. For new openings or structural changes, we pull permits as needed and handle coordination with the village.
Can you change the size of my window openings?
Yes. Because we understand framing and structural systems, we can resize existing openings — make windows larger, add new windows, or reconfigure the layout. This is where we separate from standard installers who can only work within the existing rough opening.
Are you licensed and insured for window installation in New York?
Yes, Titan Project Solutions is fully licensed and insured in New York State for window installation and related carpentry and exterior work. We carry full liability insurance and workers' compensation on every job.
