Removing the Old, Damaged Brick Mold

With a keen eye for identifying damage and a well-stocked toolkit at your side, you’re now ready to tackle the removal of the old, failing brick mold. This stage demands patience and careful execution to avoid collateral damage to the surrounding brickwork, siding, or window frame. Remember, the goal is to remove the old brick mold cleanly without creating new problems.

Preparing the Area

Before you even touch a tool, take a moment to prepare the work area. Use a drop cloth or plastic sheeting to protect the ground below from falling debris and paint chips. This will simplify cleanup and prevent accidental staining or damage to landscaping.

Loosening the Old Brick Mold

The initial step involves carefully separating the old brick mold from the window frame and surrounding surfaces.

This is best accomplished using a sharp putty knife or a thin pry bar.

Gently insert the tool between the brick mold and the window frame, starting at a corner or along a seam.

Apply steady, even pressure to gradually loosen the bond. Avoid excessive force, as this can splinter the wood or damage the surrounding materials.

Work your way around the perimeter of the brick mold, loosening it incrementally.

Removing Fasteners

Once the brick mold is partially detached, you’ll likely encounter nails or screws that are still holding it in place. Use a nail punch or a screwdriver to carefully remove these fasteners.

If the nails are deeply embedded or rusted, you may need to use a nail puller or a specialized pliers to extract them.

Again, proceed with caution to avoid damaging the surrounding surfaces.

Complete Removal and Inspection

With the fasteners removed, you should be able to gently pry the brick mold completely away from the window. If it’s still stubbornly resisting, double-check for any remaining nails or screws that you may have missed.

Once the old brick mold is removed, take a moment to thoroughly inspect the exposed area.

Look for signs of hidden rot, insect damage, or water intrusion.

Address any underlying issues before installing the new brick mold. This is an excellent opportunity to seal any cracks or gaps in the window frame or surrounding brickwork.

A Word of Caution

Throughout the removal process, remember that patience is key. Rushing the job can lead to mistakes and damage.

This ensures a weathertight seal and a professional-looking finish. Accurate measurements and clean cuts are the key to success here.

Cutting and Fitting the New Brick Mold

Precision Measurement is Paramount

Before you even think about firing up the miter saw, meticulous measurement is crucial.

Measure the height and width of the window opening where the brick mold will be installed. Double-check your measurements to avoid costly errors and wasted material.

Remember the old adage: measure twice, cut once. Account for any angles or irregularities in the opening. If your brick mold is going to meet at a 45-degree angle, calculate accordingly so the total length matches your opening.

Mastering the Cut: Miter Saw vs. Hand Saw

The choice between a miter saw and a hand saw often comes down to personal preference and the tools you have available.

A miter saw offers superior precision and speed, making it ideal for achieving clean, accurate cuts, especially when dealing with angled edges. A powered miter saw is highly recommended.

A hand saw, while requiring more effort and skill, can still produce excellent results with careful execution. A miter box can be used with a hand saw to guide the blade and ensure accurate angles.

Regardless of your chosen tool, always use a sharp blade to prevent splintering and ensure a clean cut.

Always wear safety glasses when operating any saw.

Cutting with a Miter Saw

1. Set the miter saw to the correct angle. For 45-degree corners, this is the standard setting.
2. Secure the brick mold against the fence of the saw.
3. Make the cut with a smooth, controlled motion.

Cutting with a Hand Saw and Miter Box

1. Place the brick mold in the miter box, ensuring it is snug against the sides.
2. Guide the hand saw along the slots in the miter box.
3. Apply even pressure.

Ensuring a Level and Secure Fit

Once the brick mold is cut, test its fit against the window opening. It should fit snugly and evenly against the surrounding surfaces.

Use a level to ensure that the brick mold is perfectly vertical and horizontal. Adjust as needed by shimming behind the brick mold until it is level.

Attaching the Brick Mold: Nails or Nail Gun?

The attachment process involves securing the brick mold to the window frame using nails or a nail gun.

A nail gun offers speed and efficiency, driving nails quickly and consistently. A hammer can also be used, but it requires more precision and effort.

Use galvanized or stainless steel nails to prevent rust and corrosion. Space the nails evenly along the length of the brick mold, approximately 12-16 inches apart. Drive the nails straight and flush with the surface of the brick mold. Avoid over-driving the nails, as this can damage the wood.

Covering Nail Holes: The Art of Wood Filler

After the brick mold is securely attached, you’ll likely have nail holes that need to be filled. Use a high-quality wood filler that is paintable and sandable.

Apply the wood filler to the nail holes using a putty knife, pressing it firmly into the holes to ensure a complete fill.

Allow the wood filler to dry completely according to the manufacturer’s instructions. Once dry, sand the filled areas smooth with fine-grit sandpaper. This will create a seamless surface for painting and ensure a professional-looking finish.

Once the old brick mold has been carefully extracted, you’re ready to begin fitting its replacement. This stage demands precision and attention to detail.
This ensures a weathertight seal and a professional-looking finish. Accurate measurements and clean cuts are the key to success here.

Sealing and Finishing for Longevity

With your new brick mold carefully fitted, the next crucial step is protecting your investment against the elements. Effective sealing and finishing are paramount not only for aesthetics, but also for long-term durability.
This involves strategically applying caulk to create a watertight barrier and then priming and painting the brick mold to shield it from moisture, UV rays, and other environmental factors.

Caulking for a Watertight Seal

Caulk acts as the first line of defense against water intrusion, which can lead to rot, mold, and ultimately, structural damage. Selecting the right type of caulk is essential.

For exterior applications, opt for a high-quality, paintable acrylic latex or silicone caulk specifically designed for outdoor use. These caulks are formulated to withstand temperature fluctuations, resist cracking, and provide excellent adhesion to various surfaces.

Applying Caulk Effectively

Before applying caulk, ensure the surfaces are clean, dry, and free from any debris. Cut the tip of the caulk tube at a 45-degree angle, starting with a small opening and gradually increasing it as needed.
Load the tube into a caulking gun and apply a consistent bead of caulk along all seams where the brick mold meets the window frame, brick, or siding.

To achieve a smooth, professional-looking finish, immediately smooth the caulk bead with a wet finger or a caulk smoothing tool. Remove any excess caulk with a damp cloth. Pay particular attention to corners and joints, ensuring they are completely sealed.

It’s better to apply a thin, even bead than a thick, uneven one. Remember, caulk is designed to fill gaps and prevent water penetration, not to act as a structural adhesive.

Priming and Painting for Protection and Aesthetics

Priming and painting your newly installed brick mold not only enhances its appearance but also provides a vital protective layer against the elements. Primer acts as a bonding agent, promoting adhesion between the brick mold and the paint.
It also seals the wood or PVC, preventing moisture absorption and ensuring a more uniform finish.

Choosing the Right Primer and Paint

For wood brick mold, use an exterior-grade primer specifically formulated for wood. For PVC brick mold, choose a primer that is designed to adhere to plastic surfaces.
Once the primer is dry, apply two coats of high-quality exterior paint. Acrylic latex paint is a popular choice for its durability, weather resistance, and ease of application.

Consider the color of your existing trim and siding when selecting paint to ensure a cohesive and aesthetically pleasing look. Apply the paint in thin, even coats, allowing each coat to dry completely before applying the next.

Painting Techniques for a Professional Finish

Before you start, lightly sand the primed surface to create a smooth base for the paint. This helps the paint adhere better and gives a more professional result.

Use a high-quality brush or roller to apply the paint, working in the direction of the wood grain or the length of the brick mold. Avoid applying too much paint at once, as this can lead to drips and runs.
If you’re using a brush, maintain a wet edge to prevent lap marks. If you’re using a roller, overlap each stroke slightly to ensure even coverage.

DIY Troubleshooting and Expert Advice

Even with meticulous planning and execution, DIY projects can present unexpected challenges. Replacing window brick mold is no exception. Understanding common pitfalls and knowing when to enlist professional help can save you time, money, and frustration. Moreover, the choice between materials like wood and PVC can significantly impact the longevity and ease of maintenance of your project.

Wood vs. PVC: Choosing the Right Material

Selecting the right brick mold material is a crucial decision. Wood, particularly pine, is a traditional choice prized for its workability, affordability, and natural aesthetic. However, wood is susceptible to moisture damage, rot, and insect infestation if not properly protected.

PVC (polyvinyl chloride), on the other hand, offers superior resistance to moisture, rot, and pests. It requires minimal maintenance and is an excellent option for areas prone to dampness or extreme weather conditions. While PVC is generally more expensive upfront, its durability often makes it a cost-effective choice in the long run.

When working with wood, always prime and paint all sides, including the back, before installation to provide maximum protection against moisture. Use exterior-grade paints specifically formulated for wood.

With PVC, ensure you use PVC-compatible adhesives and sealants. While PVC doesn’t require painting, it can be painted to match your home’s exterior using acrylic latex paints designed for plastic.

Common DIY Problems and Solutions

Several common issues can arise during a DIY brick mold replacement. Here’s how to address them:

• Difficulty Removing Old Brick Mold: If the old brick mold is stubbornly attached, use a heat gun to soften the paint or caulk. Work slowly and carefully to avoid damaging the surrounding brick or siding.
