There are many good reasons to replace your old windows. New ones won’t be drafty, won’t require unsightly storm windows, and will tilt in for easy cleaning. They will also be more efficient than your old windows. 

Today’s best dual-pane windows are about twice as effective at retaining heat and air conditioning as the single-pane units installed just a couple of decades ago.

Homeowners get about 73% of their replacement window investment back when they resell the house, according to the National Association of Realtors’ 2016 Cost Versus Value study.

There are two ways to replace windows. Shamrock can pull off the interior and exterior trim to install a whole new window unit—and insulate all the gaps—before reinstalling the trim, the same process used during a full renovation project. Or we can install a window insert, which is a smaller unit that fits inside the existing opening, without the need for removing the existing trim.




Insert Windows
When original frames and trim are in good shape, you can leave them in place, saving time and disruption. Insert windows fit right into the existing frame, preserving much of the original look of the window. Available in custom sizes.


Full-Frame Windows 
If your existing window frame is rotted or deteriorated, you’ll want to choose full-frame windows for your replacement project. Although full-frame windows generally cost more than inserts, you’ll be able to maximize your visible glass using this method. Available in standard & custom sizes.
