To Build a Deck Attached to a House, you have to Check drainage and grading where the deck will be built and fix any problems. After that, Set the ledger against the house wall or other solid structure and attach with lag screws. Then, remember that Flashing must be installed between any wood and the house. Next, Mark the foundation with string line. You need to mark the footing and post locations.
Forth, Cast concrete footings in the ground and attach the concrete piers on top to hold the posts. After that, allow footings cure for at least a week. Then, Cut a post longer than the required length and set it in the post anchor on top of a pier. Next, check the post for plumb with using a carpenter’s level. Forth, Set the post in place and secure.
After that, follow the same procedure for all other posts. You must mark and cut them individually to allow for any height variations. After that, Nail or bolt any beams in place and attach any necessary bracing. You should add any rim joists at this time and check to see they are square. Then, decide on a decking pattern and the spacing of the deck boards.
Starting at one end of the ledger, you can mark the location of the first joist. You have to continue marking along the ledger, Transfer the joist markings to a scrap piece of lumber and mark the beam opposite the ledger. Next, Add joist hangers and fasten the joists in place. You need to set the joists so the crown or bowed side faces up. You must add any required blocking for stability.
Forth, set posts for railings, benches and overheads in place. You should install any plumbing or wiring. You can install railings that go through the deck. After that, Add stairs now or wait until the decking is finished. Then, apply any protective finishes to the deck substructure.
Next, Cut the decking boards to the correct length and start laying them across the joists. You have to start at the ledger and setting the convex side up if attractive. Forth, Fasten boards to the deck with nails or screws. You need to add spacing between the boards as needed. After that, Adjust the width of the final board as needed with setting a slightly wider board in place or cutting one so it is less wide.
You must check as you go along to plan for this. When the final board is set, you should cut off any long ends. Then, add any railings that sit outside the deck and any stairways not added earlier. Next, Add amenities such as benches and planters. Last, Apply any protective finishes.
