Vinyl Siding Tip: How to Attach Stuff to Vinyl Siding

So you’ve got vinyl siding and you’d like to attach something to it without causing some potentially big issues.

…well here’s what the experts do…

Rule #1) Allow For Movement!

I can’t stress this enough, you must allow vinyl siding to move BECAUSE it typically expands and contracts 1/4″ (one quarter inch) per 12′ (twelve feet).  If you don’t allow vinyl siding to move it will most likely buckle and warp under the pressure.
So MAKE SURE the vinyl siding can slide back and forth at least 1/4″ in all areas.

Rule #2) Caulk Any Holes.

If you drill a hole through vinyl siding, caulk the hole up with clear silicon or color matched caulking.

Rule #3) Use Vinyl Siding Mounting Accessories if Possible.

There are several vinyl siding accessories designed for attaching things to vinyl siding.  The most common are called J-Blocks and they are typically used to mount lights to a wall with vinyl siding on it.  Check with your vinyl siding supplier to find out what accessories are available for your specific type of vinyl siding.
You can also do a search like this one “vinyl siding mounting” to find after market solutions.

For Custom Solutions

You can remove the vinyl siding (you’ll need a Vinyl Siding Removal Tool), mount your item directly to the wall, make sure to compensate for possible moisture and water considerations, install J-channel around the item and re-install your vinyl siding.  This is typically what is done for items that can not be removed from the wall or other custom applications.

Vinyl Siding TIP) Keep Extra Siding On Hand!

It is a very good idea to keep extra vinyl siding on hand.  You never know when you might need a piece or two for a repair.

    Yes, this is a very good point and I agree with it. Most people don’t know that after several years it will be hard to look for the exact same design of vinyl siding as your old ones. Having some spare will make it easy for you to do repairs or replacement.
