Is your deck safe? When was the last time you took a good look at your deck? Has it been cleaned and sealed lately? Are the railings still secure? Is the decking cracked and worn? Is the structure still solid? Here’s a few things to look for to make sure your deck stays in good and more importantly safe condition.
1. Structure: Take a look under your deck if you can. This is one area most people don’t pay attention to but with deck collapse stories becoming more common it’s best to keep an eye on this. Look at how your deck is connected to your house. Does it look solid or is the ledger board (first board bolted to the house) pulling away? Check that the floor joists are still attached to the ledger, preferably with metal hangers.
Some decks are built separate from the house and will have posts and beams closer to the house to hold them up. This way any movement in the deck or the house will not damage the other. Look at the posts holding the deck up and make sure they aren’t leaning one way or the other.
2. Decking: Check that the decking boards themselves are not rotting through or cracked so bad that they could break. Check to see if any nails have popped up to pose potential tripping hazards.
One way to tell if a wooden deck needs sealed is to drop some water on it. If the water still beads up the sealer is still good. If it soaks in the deck is probably due for a cleaning and sealing. Clear sealers only last about a year while colored stains can last two to three years. Just because it’s pressure treated lumber doesn’t mean it won’t need sealed.
Composite decking doesn’t need sealed but you still need to keep it clean. When it was first introduced it was advertised as “no maintenance” but manufacturers have changed their tune on that and now admit that it does require some cleaning to keep it looking good.
For either type if you’re going to use a pressure washer to clean the deck make sure you use a gentle nozzle. A pressure washer with too much pressure will actually strip layers of soft wood away causing deep ridges that hold dirt and moisture and accelerate the decay of the wood.
3. Railings: I cringe when I look at how most railings are built. Posts are notched and nailed to the outside of the deck. You can literally push them over. The notching weakens the entire posts and gives the wood a path to split and break off. Until recently the Codes didn’t really address this issue and many unsafe railings were built. Railings should be bolted through and braced back to at least two floor joist by wood blocking or specialized metal brackets. All railings will have some movement to them if you push on them but if you wouldn’t feel comfortable leaning against them they need to be replaced.
Nothing ruins a party faster than having your guests fall through the railing of your deck and getting hurt. Well, maybe that crazy friend that likes to go streaking but that’s not really a deck issue.
