Deck hangers need Hanger Nails Not regular nails or screws
Most decks I see are not built correctly
Why So Many Backyard Decks are Unsafe
Backyard decks are often the summer spot for parties - or refuge from a stressful day.
But it's estimated as many as four million decks in this country are unsafe.
Just this Saturday a man was trapped for two hours on his deck in Liberty Township when it collapsed.
In 2005, 13 people were hurt when a deck that was not built to code collapsed in Symmes Township. The bolts attaching it to the house were too small.
And in 1999 - eleven people were hurt in a deck collapse during a Riverfest celebration in Covington.
An investigation turned up signs of rot, metal fatigue, and water damage.
In this Money Alert: Local 12's Paula Toti shows why it may be time for many of us to invest in deck maintenance.
At least 30 deaths since 2000 have been attributed to deck failures. 12 people died when a three tier deck in Chicago collapsed in 2003. Dozens were injured including the cousin of a home inspector from Blue Ash.
"He was on the top tier again it had not been maintained properly.
And people who were doing it were doing it improperly."
Mike Hesterberg's cousin recovered .... but when Mike inspects decks ... the Chicago nightmare is close to mind.
He's seeing a lot of Tri-State decks with problems.
"I would say 98 percent of the time .. Possibly even greater than that."
That's not to say they'd collapse.
Sometimes the risers on stairs are improperly spaced like this set. It's a tripping hazard.
Railing can get loose over time.
They should take 200 pounds of pressure without moving.
Often there's been poor maintenance ... and building codes have changed over the years.
These spindles were code 27 years ago.
Today a family buying this home with small children would want to add lattice work or more spindles to narrow the gap ... and chance of a child getting hurt.
"What happens is decks are normally built by the homeowner."
A homeowner who may or may not get a building permit.
Even when decks are done by those who should be experts ... problems are common.
"What you're getting into is quickness to build and sometimes permits are given and then the deck is on,
a lot of ways to slip between the cracks in any system."
"I was concerned about having people on the deck if strong by today's standards."
This homeowner was concerned about the nails on her deck.
The proper nails in the proper places are fine. But where the deck meets the house ... bolts are needed.
"That ledger board should be bolted to the structure, in this case only seeing nails."
Nails can cause a pancake collapse like this ... and pull away from a home the way a hammer can remove a nail from a board. Even bolts should be checked.
Mike stopped using his own deck when he found the bolts pulling away from the home.
You can see it if you look to the center of the screen in the crack of the wood.
And the bolts should be bigger for the weight on this deck and should be closer together.
And they should be placed up and down, up and down in this case they are all straight.
Mike Montgomery is an engineer who tells homeowners what fixes are needed.
Sometimes it's not expensive.
This deck had a sagging beam.
"An easy solution is to come in and add another concrete footing to ground and add another post, and bolt to the beam."
This Mike also knows someone who was in a deck collapse in Covington.
If you buy a home ... make sure the deck is inspected.
Ask for proof of a building permit and certificate of occupancy.
Finally, if you own a deck ... protect your investment.
Regularly have it power washed and waterproofed.
Even pressure treated lumber will decay without proper care.
One thing missing from many decks built by amateurs is metal flashing between the house and ledger board.
It prevents water from entering the house.
If you have concerns about your deck, contact a home inspector or engineer.
