DIY Deck Removal (Part 1)

Posted May 28, 2009 4:45 PM by Steve Melito

Maybe you spent part of Memorial Day weekend sitting on your deck, sipping your morning coffee or enjoying a cold beer (or two). If so, good for you! As for me, I spent five hours of my holiday demolishing a pool deck that looked like it belonged on the set of The Brady Bunch.

Ever since last summer, when my youngest came close to scaling the deck for our aboveground swimming pool, I've been worried about the wooden monster in our backyard. Yes, the pool deck was ugly - in a 1970s Southern California kind of way. But more importantly, it wasn't safe.

Nails protruded from boards whose redwood stain had turned gray. The decking wasn't pressure-treated and dry rot was evident. The wobbly gate was beyond repair. Worst of all, the railing used flimsy planks that were oriented the wrong way (horizontally instead of vertically, as the picture above shows). For a child who is strong enough to hoist himself onto the edge of the deck and smart enough to start climbing, such a design is what we grownups call a "ladder".

Compared to some of the stuff that frankd20 does in this blog, my demolition project was a trivial one. But an errant cut could have pushed the deck into the swimming pool or flattened the 120-VAC conduit for the pool filter. How's that for drama? (And just try explaining that one to your wife.)

Fortunately, my DIY demolition project took only five hours. Even better, the tools I needed were simple ones: a pry bar, a reciprocating saw, a hammer, a sledge hammer, and an extension cord. My neighbor offered his Kubota to pull the deck away from the pool, but his tractor was in service at the cemetery.

Before I begin with the play-by-play, I'd like to give my personal seal of approval to a $35 (USD) Ryobi variable-speed reciprocating saw (model RJ162VP). Weighing just 6.3 lbs., this demolition tool has a stroke length of 1-3/16" and 6.5-amp motor. The industrial reciprocating saw blades that I used were pretty good, too. Made by a company called Blu-Mol, they bent but never broke.

Two dogs ran around the backyard during this project, but no animals were harmed in the making of this blog-entry. Unfortunately, the author can't say the same thing about himself. But I'm getting ahead of myself here, and I really would like you to click here for Part 2.

Moose - good stuff - sure hope you were able to pile that stuff up & have a great big 'ol bonfire for the kids - they love that kinda stuff - heh

BTW - I was kinda saddened that your tool-set didn't include a chainsaw

Blends well with the carnage.....

No, no, no! First, double check if that is pressure treated lumber. Even pressure treated lumber rots eventually.

Pressure treated lumber contains arsenic among other wonderfully bio-hazardous chemicals and burning it releases a toxic cloud into the air. Bad news for those hanging around the "camp fire".

Even cutting the stuff with power tools releases dust in the air. You should wear a mask when cutting the stuff.

Thanks for your comment, Anonymous Hero. I have a question for you about pressure-treated lumber.

This might not be especially clear in the picture, but the far side of my backyard has a retaining wall that is made of old railroad ties. Do you think that such lumber might have been treated with arsenic? And if so, is likely that bio-hazardous chemicals would ever "leach out" into the ground?

The reason I ask is simple. The best place in my yard for a garden is near those old railroad ties!

I don't know. I think they treat those ties with creosote, but I am not sure. They are a form of treated lumber, but of what, I don't know.

I live in So.Cal. and have replaced and built many decks over my many years. First---as far as what the material used in the deck and retaining wall are----It depends on when they were built--as environmental controls were implemented over the years, formulations of rot-inhibiting compounds changed-- i.e.--Creosote, then copper based, to the newer formulations)-as far as "railroad ties"---they are creosote impregnated---terrific resistance to rot--(telephone poles, railroad ties etc.)--I would not worry about them as long as they are where they should be, in the ground--don't eat them , burn them, or use them for exposed contact structures(jungle gyms etc.)--As far as burning or wood working, do not work redwood, western red cedar, or any other rot-resisting materials without a good mask, and make sure the dust is properly disposed of--many cases of lung cancer in wood mills that made this stuff---the same stuff that inhibits decay also can really impose on your respiratory system--I wish the new plastic decking(Trex etc.) was all it is hyped up to be, but it gets hot and deforms in warm climates..maybe better in cool climes---my two cents--feel free to pick my brain---been doing it for 30+ years---C-MAC

Thanks, C-Mac. And welcome to the conversation. The railroad ties look like they've been there for a long time, so I'm guessing that they're creosote-impregnated.

I am removing old deck planks, too. They are at least twelve years old. They were in good shape when we moved in. I painted them with supposedly premium deck stain about 9 years ago, but they have gone to dry rot since(Central Florida swamp climate).After my foot went through one board, I decided it was time to rebuild.

I can't tell if the planks are PT or not. They are standard size 1 x 6, not 5/4 deck planks. If they are PT, I will take to the landfill, otherwise, they would make great bonfire fuel. Is there a way to test for PT chemicals?

Thanks for the comment CUTiger. Believe it not, my youngest got mad at "Daddy" for tearing the deck down!

I'm thinking of using the leftover lumber to build a baseball backstop for our backyard, but would have to track down some blueprints. We play a lot of whiffle ball, and chasing down foul tips and missed pitches isn't as much fun as hitting a home run.

As for the chainsaw, it's probably a good thing I don't own one - as you'll see in Part 2!

I can't wait to read part 2 of this series!!! You say that no animals were hurt in the making of the blog entry... but you are a Moose and if you hurt yourself, you did hurt an animal! I sure do hate cliff-hangers

Thanks for your comment, Jaxy. I managed to avoid a trip to the ER, but my pride was bruised a bit. Check out Part 2 (which is now live) to see why!

Ok guys, do you think spent engine or gearbox oil is good to treat wood with (minus its echo friendliness)? And what is the best bio-friendly stuff to use?

Are those reciprocating saws actually any good?
I've seen 'em used on TV and all they seemed to do was shake the timber into submission. It seemed to me that a few strokes with a decent bow saw, or one of the new style hard point saws would have done it quicker, quieter and safer.

Reciprocating saws ("Sawzall's etc.) are indispensible in demolition---The more powerfull ones, like the Milwaukee "Supersaw zall" pulls almost 15 amps, and has a longer stroke, ideal for open cutting , and very aggressive work.--For more "delicate " work, get a less powerful one, with a shorter stroke---this will allow cutting tighter spaces i.e. between walls) without the blake cutting into the other side of the wall--also less likely to jam the blade. As far as shaking things apart, that will only happen when the piece being sawed is loose, or not firmly held or fastened, therefore the saw and the piece to be cut move in harmony with each other, a "handshake", so to speak. Just make sure the piece to be cut is firmly attached or held. C-MAC

Ah, that accounts for it...I saw some muppet on TV trying to saw a wobbly banister, when it would have been quicker to hit it with a sledge hammer.
