The question on how to install retro fit windows has been raised several times by my subscribers and I have tried to provide customised answers to each of those who sent me personal emails. However, I have realised the need to share this information publicly.
I will provide some quick-start points to help stir you towards the right direction. One thing I should mention is that installing retrofit windows is quite easy. You just need to pay attention to a few details and you will be able to do it with ease.
o First you need to prepare the window. Do this by drilling 3/8 inch holes where you will screw it into balance. In most instances you need to drill 3 holes for the sides and 3 across the top. There is no need to drill any holes in the bottom track.
o Now remove the old panels and then put a bead of caulk on the old frame. Make sure it is quite a heavy bead.
o Now set the try and set the old bottom of the window onto the old bottom track. Once you’ve done that simply raise it into position. You may need a helper for this.
o Use the flush or retrofit lip to act as a stop that will hold the window into place.
o You may need to have the helper remain outside holding while you go inside the house to centre the window in the opening.
o Then you must adjust for out of square condition. You can do this by shimming the bottom right or left corner.
o Once you have it squared up then drive a deck screw into the holes you drilled earlier and into the wood studs.
These are the basics on how to install retrofit windows.
