Key takeaways
- You can add grids to your current windows using aftermarket or DIY kits sold online.
- We do not replace just the glass or install grid-only add-ons; we replace the full window as a system.
- Our process removes wood rot and seals the opening so it stays airtight and watertight.
- Aftermarket grids are a cosmetic change and do nothing for the condition of the frame or seal.
- A full replacement protects your home and adds value that a surface update cannot.
A grid upgrade looks like the cheapest way to change a window’s style, and that is what makes it tricky. Plenty of products promise the look for a fraction of the replacement cost, so the temptation is real.
The question before you buy one is whether you can add grids to an existing window in a way that holds up, or whether you are masking a problem you cannot see. The answer comes down to one thing most people overlook.
Can You Add Grids to an Existing Window?
The option exists, so the next step is understanding what each route involves. One path is a simple cosmetic update, and the other is a full replacement that addresses the frame and seal behind the glass.
How to Add Grids to an Existing Window
If you only want the updated look, you can use aftermarket kits or DIY products sold online. These attach to the glass or frame and change the appearance without touching the rest of the unit. For a window that is still in good shape, that may be all you need.
Why We Don’t Offer Glass-Only or Grid-Only Work
We take a different route at Fairway Exteriors. We do not install new glass on its own, and we do not add aftermarket grids as a standalone service. Our focus is on replacing the full window as one complete system because that is what actually protects your home.
What Our Full Window System Covers
When we replace a window, we treat the entire opening, not just the part you can see. A complete replacement moves through four phases:
- Remove the old window
- Repair any wood rot in the opening
- Seal the opening airtight and watertight
- Install a new, properly fitted window
Each phase sets up the next, which is why we never stop at the glass.
Stopping Wood Rot Before it Spreads
Before anything new goes in, we remove the old window and fix any wood rot in the opening. Rot left in place keeps spreading and weakens whatever sits on top of it. Clearing it first gives the new window a sound surface to anchor to.
Sealing for an Airtight, Watertight Fit
Once the opening is sound, we foam, caulk, tape, and flash it so air and water cannot get through. That sequence is what makes the install airtight and watertight. We then set the new window into an opening that is ready to hold it for years.
Pro Tip: Grids change how a window looks. They do nothing for drafts, leaks, or rot. If you feel air or see moisture, the fix is in the frame and seal, not the grid.

Is a Grid Add-On or Full Replacement Right for You?
The right choice comes down to the state of your current windows and what you want them to do.
When a DIY Grid Update Fits
If your windows are newer, well-sealed, and free of rot, an aftermarket grid kit can give you the look you want at a low cost. This is a reasonable do-it-yourself project if you are comfortable researching the products and handling the installation.
When Full Replacement Pays Off
If your windows are older, drafty, or showing any sign of rot, a cosmetic grid only covers up the real issue. A full replacement solves the underlying problem and updates the look at the same time. It is the option that adds lasting value instead of a temporary touch-up.
Key Takeaway: Match the fix to the window. A grid kit suits a sound window. An aging window needs a full replacement, not a surface change.
Frequently Asked Questions
1. Can I Add Window Grids Myself?
Yes. Aftermarket and DIY grid kits are available online, and it is a project you can take on if you research the product and method first.
2. Do You Replace Just the Glass or Install Aftermarket Grids?
No. We do not offer glass-only replacement or grid-only add-ons. We replace the full window as a complete, sealed system.
3. What Does Your Full Window Replacement Include?
We remove the old window, fix any wood rot, then foam, caulk, tape, and flash the opening before installing a new, properly sealed window.
4. Will Adding Grids Fix a Drafty Window?
No. Grids are cosmetic. A draft points to a sealing or frame problem that only proper replacement can correct.
5. Do New Windows Come With Grids Built In?
Yes. New windows can be ordered with grids built into the unit, so you get the style you want without an aftermarket add-on.
The Right Answer for Your Home
What this Means for You
You can update the look on your own, and for a window in good shape, that may be the simplest path. For a window that is aging or letting in air, the smarter move is a full replacement that fixes the frame, seals the opening, and refreshes the appearance in one step.
