A highly-built deck may last for years. But a deck that’s rotting or missing fasteners, or that moves whenever you walk on it, can be dangerous. Decks built by inexperienced do-it-yourselfers, not inspected after they were built, or maybe more than 10 years old (building codes were different in those days!) are vulnerable to serious problems. Each and every year, folks are severely injured, even killed, when decks such as these fall down. It has usually happened during parties as soon as the deck repair Lincoln NE was full of guests.
Now for the good thing. The majority of the fixes are quick, inexpensive as well as simple. Home centers and lumberyards carry the tools and materials you’ll need. Or visit strongtie.com to discover local stores that stock anchors, post bases and connectors.
In this article, we’ll reveal to you the warning signs of any dangerous deck-and ways to fix the problems. If you’re still not sure whether your deck is protected, have it inspected by the local building inspector.
Fasten the ledger to the house with lag screws. Drive them fast with a corded drill and socket. Every lag screw must have a washer.
The ledger board holds in the end of your deck that’s versus the house. In case the ledger isn’t well fastened, the deck can merely fall from the house. A building inspector we talked with said the most frequent trouble with DIY decks is ledger boards not properly fastened towards the house. For any strong connection, a ledger needs 1/2-in. x 3-in. lag screws (or lag bolts when you have access in the inside to fasten the washers and nuts) driven every 16 in. This ledger board was fastened mostly with nails rather than lag screws (and no washers).
Starting at one end from the ledger board, drill two 1/4-in. pilot holes. Counterbalance the holes therefore the top isn’t aligned with all the bottom hole. Then drive the lag screws (with washers) utilizing a drill plus an impact socket (you’ll need a socket adapter which fits inside your drill). Don’t countersink the screws-that only weakens the ledger board.
Fill every nail hole in joist hangers, using joist hanger nails only. If you find other sorts of nails, replace them joist hanger nails.
Granted there are a variety of nail holes in the joist hanger-nonetheless they all need to be filled. Otherwise, the hangers can pull loose from the ledger board or rim joist. Deck builders sometimes drive a number of nails into the hangers to support them into position, then forget to include the remainder later. This deck had only a single nail in a few joist hangers. In other places, it had a bad nails. Joist hanger nails would be the only nails acceptable. These short, fat, galvanized nails are engineered to support the hangers set up under heavy loads and resist corrosion from treated lumber.
Prop in the deck with temporary braces so you can remove the rotted post. Stop jacking if you hear the deck start to creak.
Deck posts that rest right on footings soak up water and then they rot, especially posts that aren’t pressure treated (like this one, which is cedar). As the post rots, it loses its strength and can’t support the deck’s weight. Newer decks keep the concrete footings a few inches above ground and use a special base bracket to keep the posts dry. Replacing a rotted post is the best solution. Before removing the post, be sure you have everything that you need to the replacement, together with a wedge anchor.
Clear grass or stone away from the bottom from the deck post. Prod along the base of the post by using a screwdriver or even an awl. When the wood is spongy or pieces easily peel away, you’ll must replace the post. Start by nailing 2x4s or 2x6s together for temporary braces. Place scrap wood on a lawn for a pad within 3 ft. in the post being replaced, then set a hydraulic jack over it. Cut the brace to size, set one end around the jack and set one other end within the rim joist. Slowly jack up the brace until it’s wedged tight. Take care not to go crazy. You’re just bracing the deck, not raising it. If you hear the joist boards creak, then stop. Then place a second brace on the reverse side from the post (Photo 1). (In the event you don’t have jacks, you can rent them.) Or set your temporary braces right on the pads and drive shims between the posts and also the rim joist.
Mark the post location around the footing, then get rid of the post by cutting throughout the fasteners that tie it for the rim joist. Make use of a metal blade within a reciprocating saw (or knock the post by using a hammer). If there’s already a bolt sticking out of the footing, apply it to setup a new post base. Or else, you’ll have to give a 3/8- by 4-in. wedge anchor. Do that by placing the post base at the marks where the old post sat, then mark the center. Remove the post base and drill the center mark by using a 3/8-in. masonry bit. Drill down 3 in., then blow the dust out of your hole.
Tap the anchor into the hole by using a hammer (Photo 2). Install the post base over the anchor. When you tighten the nut about the anchor, the clip expands and wedges tight versus the hole’s walls to hold itself in place.
Cut a treated post to suit involving the post base and the top of the the rim joist. Set the post into place and tack it to the post base with 8d or 10d galvanized nails (Photo 3). Place a level alongside the post. When it’s plumb (straight), tack it in position for the rim joist. Then put in a connector and drive carriage bolts with the rim joist (see Problem 4 below).
Strengthen post connections with carriage bolts. Drill holes, knock the bolts through, then tighten a washer and nut on the reverse side.
Ideally, posts should sit directly within the beam or rim joist to support the deck. In case the posts are fastened aside in the beam or rim joist, like the one shown here, the load is defined around the fasteners that connect the post on the deck. This deck had only three nails from the post-a recipe for collapse. Nails alone aren’t strong enough for this particular job, no matter how many you use. For the strong connection, you will need 1/2-in.-diameter galvanized carriage bolts.
Add two of these bolts by drilling 1/2- in. holes from the rim joist and post. An 8-in.-long 1/2-in. drill bit costs $10. The duration of the bolts depends upon the size of your post and the thickness of the rim joist (add them and buy bolts at least 1 in. over your measurement). We used 8-in. bolts, which experienced two 1-1/2- in. rim joists along with a 3-1/2-in. post. Tap the bolts through with a hammer, then include a washer and nut on the opposite side.
Stiffen a wobbly deck with a diagonal brace run from corner to corner. Drive two nails per joist.
Should your deck gets a case of your shakes if you walk across it, there’s probably no reason for concern. Still, sometimes, the deck movement puts extra stress around the fasteners and connectors. Over time, the joists can pull from the rim joist or ledger board and twist from their vertical position, which weakens them. Fastening angle bracing within the deck will stiffen it and remove the sway. The braces are mainly hidden from view and allow you to walk on your deck without feeling like it’s gonna fall down at any moment.
Operate a treated 2×4 diagonally from corner to corner, beneath the deck. Drive two 16d galvanized nails through the brace into each joist. When a single board won’t span the space, use two, overlapping the braces by a minimum of two joists. Cut the bracing flush together with the outside fringe of the deck.
Pry the siding away from the house and take off the deck board that’s on the ledger to clear just how for brand new flashing.
The region round the ledger board needs to be watertight. Even small leaks can lead to mold inside the walls of the property and, worse, the home rim joist (which supports the ledger) will rot and the ledger will fall off. Stand or crawl under the deck and look at the ledger board. When you don’t visit a metal or plastic lip over the top of the the ledger board, add the flashing. Flashing was completely missing using this deck.
To include flashing, first eliminate the deck board that runs alongside the house. When the boards run diagonally, snap a chalk line 5-1/2 in. through the house, then set the blade within a circular saw to the depth of your decking boards and stop the board ends. (Replace the cutouts following the position having a 5-1/2-in.-wide board installed parallel to the house.)
For vinyl, wood or other lap siding, work a flat bar within the siding and gently grab the nails (Photo 1). Insert the flashing behind the siding (Photo 2). For those who have a brick or stucco house, you probably won’t see any flashing as the ledgers tend to be installed directly over brick or stucco.
We used vinyl flashing, but you may also use galvanized metal or aluminum flashing. Each and every joist location, make a small cut from the flashing lip using a utility knife so it’ll lie flat over the joists. The other lip should fit on the top fringe of the ledger board.
You ought to have flashing under the bottom side of the ledger too. But since there’s no way to include it without taking off the ledger board, have a bead of acrylic caulk along the foot of the ledger board to seal out water (Photo 3).
Strengthen a loose railing post with carriage bolts. Drill a couple of holes from the post and framing. Angle the hole in order to avoid joist hangers.
Loose railings won’t cause your deck falling down, nevertheless, you could tumble off deck contractor Lincoln NE. Railing posts attached simply with nails will likely come loose, and irrespective of how many new nails you drive into them, you won’t solve the trouble. Instead, add carriage bolts. Measure the thickness of the post and rim joist, then buy 1/2-in.- diameter galvanized carriage bolts that length plus 1 in. Will also get a nut and washer for each and every. Drill two 1/2-in. holes from the post and rim joist. Cancel out the holes, keeping one about 1-1/2 in. from the top of the the joist as well as the other exactly the same distance in the bottom (be sure to avoid drilling wherein a joist abuts the rim joist). Tap the carriage bolts from the holes, then tighten the nuts before the bolt heads are set flush together with the post.
