Make sure that the window frame is ready to receive the new pane when you have removed the old glue. Find the width and the height of the opening in the sash by subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Take these measurements to the nearest hardware store or home center and have a piece of stock glass cut to size. Alternately, you can cut the glass yourself if have the tools you need.

After putting in the new glass After installing the glass, apply some caulking around the edge. This will make the glass weatherproof.

Before applying the putty on the surface, gently knead it until it becomes soft and free from lumps. Make it into pencil-sized strips. Apply the first strip in the corner of the frame, working from one corner to the next to ensure it is even and smooth.

If you sand cost of replacement windows uk wood cover it with painter's tape to protect it from damage caused by accidental sanding.

Note down the dimensions of the frame. Take these dimensions to an hardware store or home center and have the new pane made slightly smaller than the frame's opening. This will ensure that the pane fits snugly and allows for expansion and contraction.

Place the new window in the frame and push it into place firmly with your hand. Use the chisel's point or the edge of the putty blade to smudge the glaziers' points as shown in Figure 11. The glazier's points should be aligned with the top edge of the pane and the raised shoulders should be just below that lip.

Apply a thin bead of glazing compound on the edges of the new glass and into the rabbet grooves to seal and protect them. Let it dry completely and cure.

Install the new window sash after the glazing compound has dried. First, coat the wood with a thick coat of Linseed oil.

Putty

A baseball thrown at you, an errant rock or a falling branch can cause a window pane to break or crack. Most windows can be replaced easily by simply putting in a fresh piece. The glass is held in place by tiny metal clips known as a glazier's point and putty, often called glazing compound. Before installing a new pane, first remove the old one and clean up the area using an abrasive and the pull-type paint scraper or a wood chisel. Wear gloves and safety glasses while working.

Once the sash is reinstalled, you can apply a silicone caulk on the glass. This will ensure that it doesn't get soiled or discolor over time.

Remove the glazing points in the rabbets. These are the grooves in the sash where the glass is located. If they're difficult to work out, you can try holding an instrument like a heat gun to soften them before you do. When using a heat tool, be sure to not scratch the sash and its railings.

After the old points of glazing and putty have been removed make a bed for the new pane. Roll a piece of glazing compound between your hands, shaping it to be around 1/2-inch thick.
