Casement Windows

What are casement windows?

Casement windows are basically small doors. They can open inward or outward or can be put together in a double detail to have two sets of windows working together opening inwards and the second set opening outwards. This provides you with a double pane window detail but on a larger scale. Casement windows are more simple in nature but knowing how to make them operate again is more difficult when the sash have sagged (or racked), the opening has racked, the sash and opening have racked together or someone trimmed the wood of the sash after sagging to make it close better.

The problem with casement windows however is that they wear out when they are exposed to moisture constantly and the paint schedule is neglected and/or paint is improperly applied. The construction of casement windows will also help keep the sash from racking as well. Unlike double hung windows we typically have to rebuild neglected casement windows due to the issues stated.

How to remove casement windows?

Casement windows can easily be removed by unscrewing the sash from the hinge or unscrewing the hinge from the jamb. Some larger casement windows are outfitted with a removeable hinge pin just like a door should have. Having a removable hinge pin makes removing casement windows much easier.

Casement windows we have rebuilt.

We rebuilt these in-swing casement window in Seattle Washington in the Capitol hill area. These windows had previously been trimmed on the tops and bottoms by a previous contractor and were not in any condition to be salvaged. The windows were built on-site  in our mobile work truck. The opening settled to the left and every window had to be set in place and tilted to the left before nailing the joints. The Sash were overbuilt and trimmed to fit the opening. The muntins were then added to add character and privacy.

Once everything was dry fit and operating the sash are then taken to the shop for primer, glass glazing and finish coats.

The images to the left are a set of out swinging casement windows we built on-site as well in the Seattle Washington area. The sash had been neglected for a long time and were in rough shape. We built new matching sash, re-glazed the zinc panel along with some new welds and put the zinc panel back into the new sash. The windows were weather stripped with spring bronze weather stripping to inhibit air flow in and out of the home.
