An outdoor pergola is a great addition to any garden, since it adds an elegant setting as well as provides shade in summer. Pergolas have a long history, and were known to serve both a functional and an aesthetic purpose in past years. Attaching an outdoor pergola to your house might sound complicated, but it is in fact quite straightforward if you follow the steps below.


Step 1 – Cut the Lumber

Start by measuring the lumber and cutting it to form a ledger board with a width identical to that of the pergola. Make sure that the length of the board is equal to the outer edge beam of the pergola. When ready, level the board at the height you want and mark its edges on the building.

Step 2 – Drill the Holes

Drill pilot holes at regular intervals, depending on the material of the walls of your house. If you have a brick wall exterior, drill sleeve anchors into it and secure the ledger board to them. If you have a wood-framed house, use lag bolts to secure the ledger board to your house. Make sure you choose the solution which best fits your house, since you don’t want to end up structurally damaging it.

Step 3 – Mark Hanger Holes

In case you want to hang the pergola rafters off of the ledger board with metal joist hangers, use a pencil to mark the hanger holes onto the ledge, and then screw into place. At this stage, some metal may show from underneath the pergola, but you can counter this by following the upcoming step.

Step 4 – Cut Out Notches

Use a jigsaw to cut out a notch as wide as each rafter along the top of your ledger board. You can make the notches at your desired intervals. When ready, slot each rafter in the corresponding notch and secure them to the ledger board.

Step 5 – Secure the Joints

After the pergola is attached to the house, make sure that each joint in the pergola is well secured. This is very important since it helps maintain the pergola’s structural integrity in bad weather. Moreover, it also helps to support the weight of any decorative plants that you may add to your pergola later on.

Pergolas have nowadays become a common sight in gardens, since no garden is considered to be totally complete without one. Attaching your pergola to your house helps a lot in terms of structural solidity, and it also vitalizes the appearance of your house. To construct a truly reliable and functional pergola, you should follow the steps given, preferably with another pair of hands to help you out in your task. Once ready, you can sit back and enjoy your new outdoor pergola.
