Good Frame Eases Window Replacement

Question: How do I replace a window?

The current window is double-hung with sash weights, and I want to replace it with a vinyl window.

Answer: Replacing double-hung wood windows with vinyl ones is about the simplest and most cost-effective of all window replacements, as long as the main frame of the existing window is in good condition and can be reused.

Here’s how to do it:

First, remove all the trim from the four inside faces of the main frame. You don’t have to remove the ropes and weights; they can be left in the hollow sides of the window frame. But we suggest spraying expansive foam into the balance of the void to improve energy efficiency.

After the trim is removed, it becomes apparent that the main frame has an offset in it that goes all the way around. The inside half of the frame is slightly smaller than the outside half.

The replacement window comes in its own frame and is set in place from the outside, fitting into the larger opening and butting against the face of the smaller portion.

If the main frame doesn’t have an offset, wood trim is added to create one. Trim is used to cover the caulked joint between the frame of the new window and the old one.

Our first double-hung window replacement job took about 60 minutes per opening, soup to nuts: removal, installation, caulking, trim and paint touch-up.

Removal of Blinds Broke Windows’ Airtight Seal

Q: I have casement windows that used to have blinds between the two panes of glass. The previous owner removed the blinds. The windows sweat terribly, winter and summer. Must I replace the windows or is there some type of permanent repair?

A: We have good news and bad news. Sorry to be the bearer of the latter, but when the last owner removed the blinds, he also permanently broke the airtight seal around your insulated glass windows.

It is interesting that the last owner disassembled the windows, removed the blinds and reassembled everything without realizing he was destroying the insulation value of each window. The brand you have is probably Pella, so you would be wise to call a Pella dealer and ask to have the insulated glass sections replaced. Pella probably will be more expensive than a local glass company, but the warranty might be better.

With insulated glass, warranty is everything. Some window companies offer lifetime warranties.
