How to Anchor a Pergola Into a Stone House

A pergola can provide shade and architectural interest to the exterior of your home, providing a relaxing spot for sitting or entertaining. While pergolas can be free-standing, it's wise to anchor a pergola that's adjacent to your home to the exterior wall. Depending on the wall materials, you'll need different tools and techniques to anchor your pergola to the wall.

Ladder
Tape measure
Safety goggles
Impact drill with a carbide tip
3-inch masonry anchors
Hammer
2-by-10 inch board
Circular saw
Drill
1/2-inch wood drill bit
5-inch-long 1/2-inch stainless steel lag bolts
Matching stainless steel washers

Instructions

- 1
  Place a ladder against the wall at the position you've determined for the pergola's end board. Start at one end of the location and measure and mark a spot every 16 inches onto the stone wall.
- 2
  Drill 3-inch-deep holes into the walls at the marked locations with an impact drill equipped with a carbide tip. Be sure to wear safety glasses as you do this.
- 3
  Place a masonry anchor into each of the holes and tap them in flush with a hammer.
- 4
  Cut a 2-by-10 inch board to the length you've planned for the pergola's end piece board. Drill holes through the board every 16 inches that correspond to the location of the anchors on the wall.

  Place the board into position and insert lag bolts with washers into each hole. Tighten them down with a socket wrench until the board is firmly attached. The end piece is now ready for the addition of the pergola's mounting hardware and cross pieces.
