Why Mounting Blocks For Ribbed Siding Are Necessary
From my experience working with ribbed siding, I’ve found that mounting blocks are absolutely essential for a clean, secure installation. Ribbed siding has a textured, uneven surface, which makes it difficult to attach fixtures like lights, mailboxes, or house numbers directly onto the siding without risking damage or an unstable mount. Mounting blocks provide a flat, stable surface that ensures whatever you’re attaching sits flush and secure.
Another reason I rely on mounting blocks is to protect the siding itself. Without them, screws or nails can cause cracks or allow water to seep behind the siding, leading to potential rot or mold issues over time. The blocks act as a buffer, distributing the pressure and sealing the attachment point better than if I were to fasten directly into the siding.
Finally, using mounting blocks simplifies maintenance and future changes. If I need to swap out a fixture or make repairs, it’s much easier to remove and replace the mounting block than to risk damaging the siding each time. Overall, mounting blocks have saved me time, effort, and costly repairs, making them a must-have when working with ribbed siding.
My Buying Guides on Mounting Blocks For Ribbed Siding
When I first decided to install mounting blocks on my ribbed siding, I quickly realized that not all mounting blocks are created equal. After some trial and error, I’ve learned a few key things that can help you pick the right ones for your project. Here’s what I’ve found most important:
Understanding What Mounting Blocks Are
Mounting blocks are those handy plastic or composite pieces that create a flat, stable surface to mount fixtures like lights, mailboxes, or house numbers on siding that isn’t flat — like my ribbed siding. Without them, screws might not hold well or your fixtures could look crooked.
Why Ribbed Siding Needs Special Attention
Ribbed siding has those raised ridges that make it tricky to attach things directly. I learned that mounting blocks not only provide a level surface but also prevent damage to the siding by distributing pressure evenly. It’s important to pick blocks that are thick and wide enough to bridge the gaps between ribs.
Material Matters: PVC vs. Composite vs. Wood
From my experience, PVC mounting blocks are a great choice because they resist moisture and won’t rot or warp like wood might, especially outdoors. Composite blocks are sturdy too but can be more expensive. Wood blocks can be customized easily but require sealing and maintenance.
Size and Shape Considerations
I found that choosing a mounting block size that matches the fixture’s base is crucial. Too small, and the fixture might not be stable; too big, and it looks awkward. Some blocks come with decorative edges, which can add a nice touch if you want something more than just functional.
Ease of Installation
Look for mounting blocks with pre-drilled holes or ones that allow easy drilling. I always check if the block comes with installation instructions and compatible screws. Also, some blocks have a groove on the back to fit over siding ribs perfectly, which made my installation smoother.
Matching Color and Finish
To keep everything looking seamless, I recommend getting mounting blocks that match your siding color or can be painted easily. Some PVC blocks come in white and can be painted with the right primer and paint, which helped me customize the look perfectly.
Weather Resistance and Durability
Since mounting blocks are exposed to the elements, I made sure to pick ones rated for outdoor use. UV resistance and waterproof qualities were important to me to avoid yellowing or cracking over time.
Budget and Value
While shopping, I balanced price with quality. Cheaper blocks might save money upfront but could fail sooner, costing more in repairs. Investing a little more in durable mounting blocks paid off for me in the long run.
Final Tips From My Experience
- Always measure your fixture’s base before buying.
- Test fit the block on the siding before final installation.
- Use a level during installation to keep fixtures straight.
- Seal around the mounting block edges with exterior-grade caulk to prevent water intrusion.
I hope my buying guide helps you find the perfect mounting blocks for your ribbed siding project. With the right choice, your fixtures will look great and stay secure for years!
