How to Patch Siding

Some DIY fixes work like a charm. Some don’t work at all and you end up making things worse than they started. Others work just long enough for you to get comfortable and forget about them. I’m looking at you old siding patch.

You may remember a post from about a year ago when we noticed some holes in our siding and patched ’em up using this badass goopy stuff. If you don’t remember, click the link above :) Basically, our T1-11 siding (which is pretty much cardboard) had some weak spots at the bottom where rain had splashed up over the years. We patched it with Ready Patch (the aforementioned badass goop), let it dry, slapped on some paint, and called it good enough! It was pretty awesome for a year… and then the floodgates opened (literally, it flooded like crazy here in Houston) and our patches decided they had taken enough wear and tear.



We decided ok… time to suck it up and pay to get this siding replaced. But while talking to the siding guy, he said if we didn’t want to replace the whole face of the siding, we could just patch the bottom of it with a protective board. He pointed to the board you see along the bottom of the siding in the photo above. See that? He said that was actually a patch that the previous owner had probably done. Basically, as long as there’s no moisture currently trapped, you can just patch over the bad stuff with a new board to protect it!

Since we didn’t want to pay $1000 for the whole face of siding to be replaced (after all, the rest of it was in good shape), we decided to try our hand at this new type of patch.

First things first, we had to rip off the old board patching the bottom. Evan used a utility knife to score the paint/caulk where the board met the siding. Then he used a tiny crowbar to pry it off. See below!


Yep we are incorporating gifs now. But only sometimes. When we remember to :)

When Evan pulled off the board, it took off a good chunk of the old siding with it. Lots of damage, but all dry at least!

Then it was time to put up the new boards. We needed about 10-1/2 feet of wood, so we picked up two 6-foot pieces of 1″x10″ because we couldn’t fit a 12-footer in either of our cars. We grabbed some bricks from our garage to support the boards and used a level to make sure everything was aligned correctly.

Evan nailed it in and grabbed the second board. Halfway through nailing it in, we started noticing that at least one of these boards was not flat. Or maybe the side of our house was not flat. Either way, it was not good.


It may not look like much in the photo, but every time we tried to hammer in whatever part of whatever board was gaping, it would pop out a different corner. With daylight fading, we decided not to waste any more time on dumb non-flat boards. We went back to Home Depot looking for other options. And what we found was even better than our original plan!

First off we found this roll of waterproofing tape called Protecto Wrap that’s typically used to seal off windows and doors. We decided since our wall isn’t totally flat/straight we might end up with gaps even if we buy new boards… so we should seal it with the wrap as extra protection.

We scraped off all the loose bits from the old siding before rolling out the wrap. It was definitely easier doing this with two people. Evan held the roll while I pressed it against the house. This stuff was SERIOUS. The adhesive was sorta tar-like and it molded to all the grooves in our siding.

The second thing we found at Home Depot was some hardiplank siding we could use instead of regular wood. This was awesome for three reasons- one: it’s waterproof, two: it’s flexible, and three: it’s cheaper!

It wouldn’t fit in our car so we had to borrow Evan’s dad’s truck. Worth it though! You can see how flexible it is in the photo below.


We cut it down to size with a jigsaw. It was a little tricky to cut because the blade wanted to do its own thing, so Evan used our right angle (and some elbow grease) to keep it in line.

It did WAY better than the original wood boards. We did have some trouble finding places nails would stick on the left side (hence the bajillion nails you see in the photo below) but in the end we got it pretty secure. And to be honest, we weren’t tooooo worried about it because the real protection was coming from that wrap we used.

After securing it, I took over with my handy caulk gun to caulk over the gaps. We went up the sides of the window frames a bit as well where the paint was cracking.

That was sarcasm. It was pretty messy. But once we painted over it everything looked great!


And now I know gifs make you looks like a crazy person. JUST PAINTING HERE I LOVE PAINT WANT SOME PAINT?!

We are pretty confident about this fix! Guess we’ll check in again in a year and let you know how it’s holding up!

    I just stumbled across your website, while looking at pinterest for house-hunting tips. I initially found your article ‘ house buying for noobs’ (which is INCREDIBLY informative!). Then further read your DYI projects and general housing blog. First, thank you for speaking to our generation. I literally am a lost noob, in a sea of real-estate! Second, I’m pretty sure I need to be best friends with you! I LOVE that you describe yourself as weird! It’s like looking at a mirror of my husband and I (newly married Oct 2014). The post on this website are useful, creative and inspiring. Please keep posting, because i’ll be sure to continue following! Thank you again for being amazing!
