Easy Process Of Installing A PVC Window Sill Nosing
PVC moldings are weather-resistant, easy to work with, long-lasting and perfect for exterior use. Nothing works better then PVC moldings when it comes to finishing off or replacing a sill nose. The sill nose strikes into the jamb or spacer as well as works to channel water away from the window. Wood become progressively worse over time, therefore, you need to install a modern PVC sill nose in order to make sure that window remains at its best.
Step 1: Pick Your Nose
- First of all, trim out the old sill nose with the help of a reciprocating saw. This type of saw trims across the nails or screws. Track down the seam at the back, where the sill nose links onto the jamb or spacer.
- Cut along the sill nose horizontally in the middle at a slight angle to the point where it connects with the jamb. The angle will help the sill nose come out without binding.
- Place, fit, or push a prybar underneath the sill nose and lift. If it breaks into pieces, no need to worry, its OK. If it withstands coming out, then you need to make another cut. When it is loose, pull the sill nose out in pieces, if required.
- Clean the area underneath the sill, due to the reason that it might be full of spiders or other insects. Using a chisel, clean and cut the edges of any vertical trim pieces square where they connect with the sill nose, or might have been damaged when you pried off the old sill. Clean the window jamb edge where the new sill contacts it.
Step 2: Angles And Notches
- Take note of the fact that the new sill has angled edges. This leans the sill nose, to a small degree, in order to make sure that water runs away from the window and drips off the front edge. If the sill has one rounded edge, then it goes to the front.
- Calculate & compute the width of the window from side to side where the old sill was eliminated. Use a miter saw in order to trim the PVC sill to the calculation.
- Examine the corners of the old sill, if you find out notches on either side, then you need to transfer the calculations and trim identical notches on the new sill. Add a bead of construction sealant to the PVC sill nose before tapping it into place with the help of a mallet.
Step 3: Holes And Caps
- Drill 4 holes, equally spaced and centered along the front edge of the PVC sill nose. Some manufacturers include a special bit when it comes to countersinking the holes to a prescribed depth & at the same time provide a clean hole for a plastic cap.
- If you don't have one, then you need to countersink the holes as needed in order to make sure that screws penetrate at least 1 inch into the jamb. Use a Forstner drill bit when it comes to a clean hole that can still be capped. Insert screws in the holes before driving the screws in tight in order to secure the sill nose to the jamb.
Step 4: Finishing Touch
- Put or spread a bead of caulk around the perimeter of the sill nose. Spread a caulk underneath and if you don't have caps for the holes, then you need to fill them with caulk.
- If you have the caps, spread PVC cement to the holes and tap the caps flush into the holes. You don't need to paint PVC sill nose, but you can paint it, if desired. If you want to paint it, then you can use paint specifically designed for PVC.
