Removing Window Casing and Sill

The start step is always the almost worrisome, right? The window itself isn't actually attached to the interior sill. The sill should be installed into the framing.

Step 1: Remove any side casing

Casing is trim that is effectually the outsides of doors and windows. Not all windows have casing, as our was just continued to drywall and caulked to hide seams. You will probable have to remove this considering the casing sits on acme of the sill, preventing the sill from moving up.

The photos below are of me removing door casing, but nonetheless steps apply.

Step by step instructions for removing casing.

To remove casing, cut the caulk line on both sides that hides the drywall and window framing seal. Drag a razor knife top to bottom to practise this, making certain to get the full caulk line if you tin can. Cut any caulk around the sill also. (photo i)

I use a crowbar to pull out the casing from the drywall. If prying, make sure use a caryatid against the wall so you don't dent the drywall. (photo 2) Cleanup the excess caulk and remove nails/staples. (photo 3 & 4)

Oft times the casing can be salvaged and put dorsum on if you lot are conscientious, but sometimes it needs replaced.

Step 2: Pry off the sill.

Employ a prybar or chisel to slowly pry the sill upwards. A hammer also helps. Keep the sill in i piece so you can employ it as a model when cutting the new sill. Then set it aside for later.

Dealing with Rot

At this phase, the biggest thing to spotter for is any rot that may be around the frame. Rot volition demand to be removed, or it will continue to spread. If you do find minor mold or rotted wood, supplant or clean and use a product like this to stop rotting.

Rot needs 2 things to happen: a disease inducing bacteria or fungus and h2o. Make sure that you are fixing the source of the water that acquired the rot.

If you notice major rot (structural or the water source can't be constitute), here is where I recommend seeking professional assistance as the window and framing may need to exist replaced.

After solving those issues, if any, here is a bully opportunity to fill any gaps if they be to ensure a more air tight seal. Take window spray cream and spray into the gaps and permit to dry. Cutting away the excess cream with a razor bract prior to installing the new sill.

Step 3: Cutting The New Sill

We made our ain here. A simple run beyond the router to create a bullnose border makes any appropriate board a proper sill. If y'all practise not have a router, almost window sill material can be found in the millwork department at a home improvement shop similar Home Depot. Hither is an case similar to ours.  Yous will need to cut information technology to size however. Mark the lath using your template from previous sill and cut.

Step four: Adhere new sill

Use nails or brad nails to install the wood board into place ensuring to nail into the framing beneath. I exercise not recommend gluing as it isn't needed and will make any future repairs more difficult.

Step 5: Add Window Trim

In our case, the window trim under the sill had some gouges and dog chewing impairment also. I elected to fill up this particular piece as the edge cuts are not piece of cake.
