Introduction

I know I have mistakenly used the term "window sill" to draw diverse parts of windows then let me clear that up first.

The very beginning thing is to take a look at your existing window sill, both from the inside and outside.

Profiling the sill olfactory organ and other finishing touches can be done Later nosotros remove the old window sill but the 2 virtually important parts to know Earlier removing the window sill are the bending and thickness of your window sill.

Other than judging the status of the window sill, it is very hard to accurately guess the sill angle just by looking at it so we will need some manner to measure the sill angle.

We will obtain the sill thickness past measuring the exterior sill nose as well every bit from the within by removing the window stool and frock.

Footstep-BY-STEP GUIDE

Measuring an Sometime Window Sill – Thickness

Step ane: Take your tape measure, become outside and take a look the bottom part of the window.  You should be able to see a protruding wood trim.  Have a measurement of the window sill nose.

Remove Interior Window Trim

Step 2: Suspension the paint seal (fig.3.ane).  Use a sharp utility pocketknife to score between the quarter round- and side trim moldings.

Pace iii: Separate two moldings (fig.3.ii).  Using a hammer, gently tap the 4″ metallic drywall spatula between the quarter round and side trim moldings.  Using a low-cal rocking side-to-side, then up-and-downward motions, gently create a small gap between the quarter circular and side trim moldings.  So notice and marker finishing nails by sliding up and down with the spatula in between the gap.

Step iv:  Using a flat tipped craw bar (i.e. Wonderbar), gently pry off the nails, making sure to work all nail points little bit at a time (fig.three.3).  Of class if you don't plan on re-using the quarter round molding, you can exist less careful and just pry them off. Echo these steps for the other quarter round molding.

Stride half dozen:  At present we need to remove the side trim moldings.  Nosotros normally do not remove these moldings when installing replacement windows simply we need clear access to the window stool and then we have to become it out. Apply the same method equally before to gently pry off the side moldings.  In lodge to remove the window without damaging the drywall, utilise the 4″ metal spatula as a backerboard against the Wonderbar.

Step 7: To remove the window stool, use a 3 lb mash hammer to gently tap the underside of the window stool (fig.4.2). A claw hammer is not recommended because you lot must strike it harder and information technology has a less surface area then it will damage the forest surface. Again, if you don't plan on saving information technology, whack information technology abroad!

Pace 8: Use the aforementioned method to remove the window apron (fig.4.4)

Please note that some window pictures may show drywall damages. That'southward because I could non discover ideal pictures from the aforementioned project and so I had to "infringe" pictures from my kitchen remodeling project.

Step 9: Take the measurement. It should exist approximately 1.5″ thick (fig.iv.six)

Measuring an Old Window Sill – Width

Step 10: Now that the window sill is exposed inside, its a simple 2 step process to mensurate the width. From the inside, take the measurement from cease-to-end (fig.5.i). Pay special attention to the side jamb and window sill. My side jamb was notched at an angle to accept the window sill (fig.5.2).
Step eleven: From the exterior, take the measurement from finish-to-end.

That'south information technology for measuring your window sill. Information technology'due south a lot of work but these steps will ensure that your replacement volition is of right superlative, angle and depth.
