How To Measure Your Windows

The first step in installing replacement windows is measuring your current windows. You need accurate measurements for every window in the home. This way, you will be able to understand the price, and get a clearer picture how much it will cost you overall.

Accurate measurements also ensure that your windows fit properly and offer maximum energy savings. Bear in mind, the company that you hire will measure the windows as well. However, it is advisable that you measure as well, just so that you are sure.

For measuring the windows, you need to take all measurements from inside your home. Use the smallest measurements, so that you ensure the windows fit inside the frame.

To measure the width of your windows, measure from the inside of the jamb on one side, to the inside of the jamb on the other side of your windows. Make sure to measure at both the bottom and the top of the windows. Always use the narrowest measurement for the width of the replacement windows.

Next is the height. Measure from the top of the sill to the bottom of the head jamb. Take measurements at three spots: the middle, the left, and the right of the windows. Always use the shortest measurements as your height.

How Are Replacement Windows Installed?

Installing replacement windows is a two-step process. The first step is to remove the old window sashes, and the second is to install the new windows. So, what’s the first port of call?

The company you hire will remove the sashes inside the existing frame. They will remove the inside stop pieces from the windows, the inside sash, and slide the outside sash to the bottom of the window.

The company will also remove and discard the parting beads. They will remove the outside sash in the same way as the inside sash. Before installing your new windows, the company will clean the window jambs thoroughly.

Replacement Window Installation: The Process

Just so that you understand the process in detail, here is a quick breakdown of the key points of the procedure:

  • Your contractors will lay a bead of caulk along the inside of the outside stops of the jambs
  • They will centre the top and bottom sashes vertically in the new frame
  • Next, they will place the header, which is called an expander, on top of the window, and caulk the top
  • At this point, they will place the window in the opening, and check that it’s all perfectly aligned. If the window is not square, they will shim as needed
  • Next, they will install mounting screws at the top and bottom of each side jamb
  • After that, they will slide the header up, and slide the top and bottom sashes up and down, to check for gaps and ensure smooth operation
  • The last step is caulking the inside of the windows and reinstall the inside stops
