Understanding Window Replacement Options: Full-Frame vs. Insert
When it comes to replacing your windows, you’re basically looking at two main options: full-frame or insert replacements.
Full-frame replacements involve tearing out everything down to the house frame—great when you’re dealing with rot issues or wanting to change your window size.
Insert windows, on the other hand, just replace the window sash while leaving your existing frame intact. They’re definitely more DIY-friendly since you won’t need to mess with removal of exterior trim or siding.
Both options can boost your home’s energy efficiency, though full-frames give us more opportunity for proper insulation.
Measuring Your Window Opening for the Perfect Fit
Now that you’ve decided between full-frame and insert windows, let’s talk about getting those measurements right.
We’ll need to measure inside the existing frame, not between the stops. For accuracy, measure height and width at three points each and use the smallest measurements when ordering.
Don’t forget to check the squareness by measuring the diagonals—if they’re different, your frame isn’t square, which might affect installation.
Also measure the depth of the window frame to guarantee proper fit.
And if you have older windows with sash weights, account for that extra space—you’ll need to remove them before measuring for replacement.
Step-by-Step Guide to Removing Your Old Window
Removing your old window might seem intimidating at first, but we’ve broken it down into manageable steps that’ll make the process smoother.
We’ll guide you through freeing your window from its longtime home without damaging essential components.
- Start by removing storm windows and score around the edges with a utility knife.
- Pry off interior stops carefully—you might want to reuse these!
- Remove parting stops to free the upper sash, then tackle the lower sash.
- For older windows, access the side jambs to remove sash weights or springs.
- Inspect the existing frame for rot before preparing for your new window, reinforcing weak spots.
Installing Your New Replacement Window Properly
Once you’ve properly removed the old window and prepared the opening, it’s time to install your new replacement window—arguably the most satisfying part of the process.
First, we’ll clean the opening thoroughly and apply flashing tape to the sill.
Then we’ll dry-fit the window to check for proper spacing before applying a bead of caulk.
Position the window carefully and secure it with shims, checking that it’s plumb, level, and square as we screw it in place.
For energy efficiency, we’ll fill gaps with spray foam insulation.
Finally, we’ll frame with finish nails and seal edges with latex caulk for that professional finish—just remember not to cover those weep holes!
Finishing Touches: Sealing, Caulking, and Trim Installation
The final three steps of your window replacement project are what truly transform it from a construction zone back into a polished part of your home.
We’ll apply elastomeric caulk along exterior casings for proper sealing, then secure trim with finish nails for that professional touch.
Don’t forget to check for gaps everywhere!
- Apply a continuous bead of caulk around the window to prevent air infiltration
- Secure exterior casings with finish nails, using a nail set to avoid damage
- Fill nail holes with wood putty for a seamless appearance
- Seal interior trim with latex caulk for both function and aesthetics
- Inspect all edges before allowing the caulk to cure completely
