At the risk of teaching all of you “do-it-yourselfer’s” how to properly construct a deck, it is worth it to us to make sure that whatever is built by whomever, is done so with safety first!
Decks do require building permits in North and South Carolina.
Archadeck has been designing and building decks for over 25 years and literally has over 23,000 decks built here in the Charlotte area. Here are some guidelines formed from our experience:
1. Ground conditions are a very important factor to start with. If there is a lot of fill dirt where you are going to place your footings, you may need a soil engineer to design a proper footing that will disperse the weight load so that your deck does not begin to sink. If there is soft or bull tallow soil, the same remedy applies.
2. It all starts with your footings. In North Carolina, we typically dig 12″ – 24″ or until we find solid soil if possible. Then you can either purchase 16″x16″ cinder blocks and make sure your 6×6 columns are placed squarely on the blocks before filling in the dirt over and around them. You may also need to add concrete depending on the conditions of the soil, the height of the deck, lateral bracing constraints, and so forth
3. Once you have passed your footing inspection, it is time to start framing. We typically will use either 2×8 or 2×10 floor joists that will attach to a 2×12 band or ledger boards we tie into the actual house if the house is on a crawl space. If the house is built on a slab, that we are forced to build what is referred to as a “free-standing” deck meaning we will add footers up next to the house wall. If we are cutting into a vinyl or fiber cement sided house, we need to purchase and install metal flashing to avoid having moisture get in behind the siding and rotting the house wall.
3. We typically will purchase pressure-treated wood deck boards that are 5/4×6 in dimension and screw them down. We space our floor joists 16″ on center unless we are using composite decking and laying the boards on a diagonal, then we will space them 12″ on center.
4. We use a 12″ fascia board to hide the ends of the decking boards to create a clean finish around the perimeter of the deck
5. Rail is required here in North Carolina once the height of the deck is 30″ above grade or greater. The standard rail height minimum is 36″. There a vast amount of choices of rail systems ranging from custom made to kits.
6. If you are installing dried lumber (that is our preference), it is important to have the deck sealed/stained shortly after installation to protect the deck itself. We find Cabot or the proprietary stain from Renew Crew to be quite effective and protecting the wood decking.
