8 Easy Steps Guide on How to Cut Off a Window Sill
So, what’s a window sill, and what’s the use of it really? Well, it’s just like any other part of the window. Wooden window owners know how extremely decorative that simple window sill and the trim can look if it’s done right.
But the main purpose of the window sill is to prevent drafts and moisture from getting into your beautiful home. It also gives additional support to the window to stay in place.
So, let’s see the steps that’ll bring you success to cut off a window sill-
Step 1: Observe The Condition of the Sill
Before you even start, it’s essential that you observe the condition of your window sill.
Sometimes the sills rot because of the harsh weather on the outside. And in other cases, water leakage on the wall might be a reason.
There are two different types of rot depending on the causes of the rot. The dry rot and the wet rot.
(i). How to Handle the Dry Rot?
Dry rots are a much common type of rot when you have extremely hot and dry weather outside most of the time. It won’t be that much of trouble to remove a dry-rotted sill as it’s still hard and dry.
(ii). How to Handle the Wet Rot?
In most of the countries where it rains most of the time, dry rot is very usual damage to the wood.
When water leaks or stays put for a long time near the window, a fungus appears and starts the rotting. The window sill will become over moisturized and rotten.
If you try to move the sill with a wet rot, it’s going to be a massacre and there will be pieces of rotten wood stuck at places.
You can try and use a hairdryer and dry the place. It’ll take some time to dry the affected place but you’ll get the job done. It’ll be a lot easier to move the sill and avoid the mess if it’s well dried.
Step 2: Cut Underneath The Window Sill
The window sill is kind of sealed under the window. So, you need to cut underneath it to free the sill from the trim board that is under it. It’s the start of taking the sill apart from the whole set of the window.
Step 3: Pry The Trim
Now, you need to detach the trim. The window sill and trims are often sealed together for a better structure.
You need to grab your putty knife and put it between the wall and the trim. That’s the weak spot that you need to focus on and pry the trim away from the wall.
It might get really hard to move the trim often. In that case, you can use your pry bar or chisel to get the task done.
Step 4: Remove The Finishing Nails
Finishing nails are applied to ensure that the joint that your window sill has with the window gets more durable.
You’ll always find finishing nails getting rusty if they’ve been in touch with water for quite a time. So, you need to be careful when you take care of those rusty nails. We don’t want you to get a Tetanus today.
You need to remove those finishing nails if you want to take away the window sill from the whole structure. You can use a plier to remove the nails safely.
Step 5: Remove The Side Window Trim
Now, you need to open your window to make things easier to work with. Grab the putty knife, put it in the weak spot between the wall and trim.
Then, remove the side window trim. No need to go too harsh on the trims. We don’t want to break anything that’s not necessary to break.
Step 6: Loosen Underneath The Window Sill
The main intention is to loosen all the stuff that gets in your way while removing the window sill.
So, it’s time to wedge the pry bar or chisel of yours underneath the window sill and loosen it as much as possible.
Step 7: Screw Two Nuts On The Sill
When you just need to remove the sill without damaging anything else, it’s important for you to be very careful.
And for that, there’s a simple trick that you can use when you’re about to bring the window sill out.
All you need is to simply take two screws and screw them on the outer portion of the window sill. Now, this trick is going to provide you an additional support which will help you remove the window sill more comfortably.
You’ll need to use your pry bar and stick it to the screws and pull lightly. Soon you’ll have your window sill out.
Step 8: Give It a Finishing
If you’re going to replace or repair the window sill, this step is especially for you.
You need to make sure that you’re getting the exact measurement for the new window sill that you had on the older one.
Use some caulk and foam and place the new window sill. It’ll make the window sill more compact and stronger than before.
And if the damage on the window sill is repairable use the wood putty and repair the window sill instantly.
