Protect Your Siding With Mounting and Siding Blocks

Whether you’re replacing siding, adding an electrical box or installing a light fixture to the side of your house, a vinyl-siding mounting block is essential for not only creating a seamless look but also protecting your home and siding from damage. If you try to mount a new fixture directly to your siding, you risk damaging it and leaving your home vulnerable to pests and water damage. Siding blocks are made of durable polyurethane and, when properly installed, prevent any holes or gaps that could let in rain or pests.


Siding mounting blocks are available in a range of colors and mount types. For a smooth and seamless look, you may want a recessed mount siding block that’ll be flush with your siding. Cover existing features, such as outdoor faucets, with a split mount block that can be caulked into place. A mount siding block with a decorative surface provides a level surface and adds character to outdoor light fixtures. Vent mount blocks feature flaps — and sometimes small animal guards — to protect utility and dryer vents without blocking them.
