How to Replace Your Window Trim (A Step-by-Step Guide)

Changing your architectural foam window trim is a great way to beautify and insulate your home. New window trims not only improve the look of your home but also protect it from the elements.

In this step-by-step guide, we’ll show you how to replace your window trims to maintain your home’s aesthetics and energy efficiency.

Step-by-Step Guide to Replacing Window Trim

With the right equipment and technique, replacing window trims can be a straightforward task.

Follow these instructions to successfully replace your window trims.

Step 1: Remove the outdated trim

Start by carefully removing the old trims with a pry bar.

Place a block of wood behind the pry bar to evenly distribute the pressure and protect your wall.

Ensure you remove any backing boards and other remnants of old panelling.

Step 2: Prepare the room

Inspect for gaps left by the old cladding around the window.

To enhance insulation, fill these gaps with expanding foam. Allow the foam to cure and expand, typically taking about 20 minutes.

For improved water resistance, apply self-adhesive window seals where the window meets the trim.

Step 3: Measure and cut the new trim to size

Measure your window precisely, using the old trim as a template.

Mark these measurements on the new trim pieces with a pencil.

Then, cut your trim to size. For precision cuts, use a circular saw to ensure the trim fits perfectly.

For safety, we recommend you wear protective goggles and a dust mask when cutting the trim.

Step 4: Install the new trim

To prevent the wood from splintering, pre-drill nail holes before attaching the trim to the wall.

Ensure the top of the trim is level before nailing. Then proceed with the bottom and side pieces, ensuring they are securely in place before fastening.

Step 5: Finish and seal

Once the new trim is installed, seal any gaps and protect against moisture by applying sealant along the edges.

Use a putty knife for smoothing the painter’s putty into nail holes.

After it dries, sand off any excess filler for a smooth finish.

Finally, prime and paint the trim to match your home’s exterior.
