Whether you’re a seasoned contractor or a homeowner looking to embark on a DIY project, this resource will provide you with the knowledge and inspiration you need to transform your home’s exterior.

Understanding the Purpose of Exterior Molding

Before diving into the specifics of different molding types and materials, it’s crucial to understand the fundamental purpose of exterior molding. While aesthetics are undoubtedly a primary consideration, exterior molding also serves several important functional roles.

Protection from the Elements

One of the most significant functions of exterior molding is to protect vulnerable areas of your home from the elements. Molding around windows and doors, for instance, helps to prevent water from seeping into the structure, which can lead to rot, mold, and structural damage. Similarly, siding trim helps to protect the edges of siding panels from wind, rain, and sun, extending their lifespan and preventing costly repairs.

Sealing Gaps and Preventing Air Leaks

Exterior molding also plays a crucial role in sealing gaps and preventing air leaks. By covering the joints between different building materials, such as siding and windows or doors and walls, molding helps to create a tighter, more energy-efficient building envelope. This can lead to significant savings on heating and cooling costs over time.

Adding Architectural Detail and Character

Of course, the aesthetic value of exterior molding cannot be overstated. Molding adds architectural detail and character to a home, transforming a plain and unremarkable facade into a visually appealing and inviting space. The right molding can complement the architectural style of your home, enhance its curb appeal, and even increase its resale value.

Types of Decorative Exterior Molding

The world of decorative exterior molding is vast and diverse, offering a wide range of styles, shapes, and sizes to suit any taste and budget. Here’s a look at some of the most common types of exterior molding:

Crown Molding

Crown molding is a decorative molding that is typically installed at the top of a wall, where it meets the ceiling. It adds a touch of elegance and sophistication to any room, and it can be used to create a more formal or traditional look. On the exterior, crown molding is typically installed at the roofline or along the top of a porch or portico.

Window Trim

Window trim is used to frame windows and add visual interest to the exterior of a home. It can be simple and understated or more ornate and decorative, depending on the desired look. Window trim also helps to protect the window from the elements and seal gaps to prevent air leaks. Common types of window trim include casing, sill, and header trim.

Door Trim

Similar to window trim, door trim is used to frame doors and add visual appeal. It also helps to protect the door from the elements and seal gaps to prevent air leaks. Door trim typically includes casing around the door frame, as well as a header above the door.

Baseboard Molding

While primarily used on interiors, baseboard molding can also be used on the exterior, particularly on porches or patios. It’s installed along the base of a wall to protect it from damage and add a finished look.

Siding Trim

Siding trim is used to cover the edges of siding panels and create a clean, finished look. It also helps to protect the siding from the elements and prevent damage. Common types of siding trim include corner trim, J-channel, and F-channel.

Rake Board

Rake boards are installed along the sloping edges of a gable roof. They protect the edges of the roof sheathing from the elements and provide a clean, finished look.

Fascia

Fascia is a horizontal board that is installed along the edge of the roof, where the roof meets the wall. It provides a surface for attaching gutters and protects the roof from the elements.

Soffit

Soffit is the underside of the roof overhang. It provides ventilation for the attic and helps to prevent moisture buildup. Soffit can be made of various materials, including wood, vinyl, and aluminum.

Dentil Molding

Dentil molding is a decorative molding that features a series of small, evenly spaced blocks. It is often used in conjunction with crown molding or other types of trim to add a touch of elegance and sophistication.

Chair Rail Molding

Although primarily used indoors, chair rail molding can be used on covered porches or patios to add a decorative element and protect the wall from damage caused by chairs.

Materials for Exterior Molding

The choice of material for your exterior molding is crucial, as it will directly impact its durability, maintenance requirements, and overall appearance. Here are some of the most popular materials for exterior molding:

Choosing the Right Style of Molding

Selecting the right style of exterior molding is crucial for achieving the desired aesthetic for your home. Consider the architectural style of your house, your personal preferences, and the overall look you want to create. Here are some tips to help you choose the right style:

Consider Your Home’s Architectural Style

The architectural style of your home should be the primary factor in determining the appropriate style of exterior molding. For example, a Victorian-style home would typically feature ornate and decorative molding, while a modern home would typically feature clean and simple lines. Research the common molding styles associated with your home’s architectural style to ensure a cohesive and harmonious look.

Think About Scale and Proportion

The scale and proportion of the molding should be appropriate for the size of your home and the features you are trimming. Oversized molding can overwhelm a small house, while undersized molding can get lost on a large house. Consider the overall proportions of your home and choose molding that is appropriately sized and scaled.

Choose a Color Palette that Complements Your Home

The color of your exterior molding should complement the color of your siding, roofing, and other exterior features. Consider using a contrasting color to highlight the molding and add visual interest, or choose a color that is similar to the siding for a more subtle and understated look. Remember to factor in the undertones of your existing colors to ensure a cohesive and harmonious palette.

Don’t Be Afraid to Mix and Match

While it’s important to maintain a cohesive look, don’t be afraid to mix and match different styles of molding to create a unique and personalized look. For example, you could use a simple crown molding with a more ornate window trim to add visual interest. Just be sure to choose styles that complement each other and create a balanced and harmonious overall look.

Consider the Overall Look You Want to Achieve

Ultimately, the style of exterior molding you choose should reflect your personal taste and the overall look you want to achieve for your home. Do you want a classic and traditional look, a modern and contemporary look, or something in between? Consider your personal preferences and choose molding that aligns with your vision for your home’s exterior.

Installation of Exterior Molding

Proper installation is crucial for ensuring the longevity and performance of your exterior molding. While some homeowners may choose to tackle this project themselves, it’s often best to hire a professional contractor to ensure a proper and professional installation. Here are some general steps involved in installing exterior molding:

Preparation

Before you begin installing the molding, it’s essential to prepare the surface. This involves cleaning the surface, removing any loose paint or debris, and filling any gaps or cracks. A clean and smooth surface will ensure proper adhesion and a professional-looking finish.

Cutting the Molding

Accurate cutting is essential for a seamless and professional-looking installation. Use a miter saw to cut the molding to the correct angles and lengths. Be sure to measure carefully and double-check your cuts before installing the molding.

Fastening the Molding

The method of fastening the molding will depend on the material of the molding and the surface to which it is being attached. In general, nails, screws, or construction adhesive are used to fasten exterior molding. Be sure to use fasteners that are appropriate for the material and that are long enough to penetrate the surface securely.

Sealing the Gaps

After the molding is installed, it’s essential to seal any gaps or cracks with caulk. This will help to prevent water from seeping into the structure and causing damage. Use a high-quality exterior caulk that is paintable and flexible.

Painting or Staining

If you are using wood or polyurethane molding, you will need to paint or stain it to protect it from the elements and enhance its appearance. Be sure to use a high-quality exterior paint or stain that is designed for the material of the molding.

Maintaining Your Exterior Molding

Proper maintenance is essential for extending the lifespan and preserving the appearance of your exterior molding. Here are some tips for maintaining your exterior molding:

Regular Cleaning

Clean your exterior molding regularly to remove dirt, dust, and debris. Use a mild soap and water solution and a soft brush or cloth to clean the molding. Avoid using harsh chemicals or abrasive cleaners, as they can damage the finish.

Inspect for Damage

Inspect your exterior molding regularly for signs of damage, such as cracks, rot, or insect infestation. Address any issues promptly to prevent further damage. Repair or replace damaged molding as needed.

Repainting or Restaining

Repaint or restain your exterior molding as needed to protect it from the elements and maintain its appearance. The frequency of repainting or restaining will depend on the material of the molding and the climate in your area. Typically, wood molding should be repainted or restained every few years.

Caulking Maintenance

Inspect the caulk around your exterior molding regularly and re-caulk any areas where the caulk is cracked or damaged. This will help to prevent water from seeping into the structure and causing damage.

Preventing Moisture Buildup

Ensure that your gutters and downspouts are functioning properly to prevent water from running down the sides of your house and damaging the exterior molding. Trim any trees or shrubs that are growing too close to the house, as they can trap moisture and contribute to rot.

Cost Considerations

The cost of decorative exterior molding can vary widely depending on several factors, including the type of material, the style of molding, the size of the project, and the labor costs in your area. Here’s a general overview of the cost considerations:

Material Costs

The cost of the molding material itself will be a significant factor in the overall cost of the project. Wood is generally more expensive than vinyl, while polyurethane and fiber cement fall somewhere in between. Consider the long-term costs of maintenance and replacement when comparing the costs of different materials.

Labor Costs

If you choose to hire a professional contractor to install your exterior molding, the labor costs will add to the overall cost of the project. Labor costs can vary depending on the complexity of the project, the experience of the contractor, and the location of your home. Get quotes from multiple contractors to compare prices and ensure you are getting a fair deal.

Project Size

The size of the project will also affect the overall cost. A small project, such as trimming a single window or door, will be less expensive than a large project, such as trimming the entire house. Consider breaking the project down into smaller phases to make it more manageable and affordable.

Additional Costs

Be sure to factor in any additional costs, such as the cost of tools, fasteners, caulk, paint, and other supplies. It’s also a good idea to set aside a contingency fund to cover any unexpected costs that may arise during the project.
