Sunjoy sells hardtop gazebos, pavilions and pergolas with steel, aluminum or cedar frames and steel roofs, and the same size can come in different constructions. The 11×13 is listed as a galvanized steel frame, as a cedar frame with a black steel roof and as a metal frame with a pitched roof, at about 11.2 by 13.1 ft and 9.4 ft tall. Reviewers say the instructions are hard to follow in places and that the roof frame has many bolts and bars.
Anton Assembler builds Sunjoy pavilions and pergolas for homeowners in Seattle, Tacoma, Everett, Bellevue, Kirkland and Redmond. We confirm which construction you have, then build it from the manual.
Retailer listings sometimes mix model numbers, so send the model number from the box and a photo of the label.
| Size | Footprint | What to expect |
|---|---|---|
| 11×13 ft | 143 sq ft | Listed with steel, cedar and aluminum frames and a two-tier steel roof. A reviewer of the cedar model says the pillars and main roof frame need two to four people. |
| 12×16 ft | 192 sq ft | A listing describes a gray cedar frame with a matte black steel two-tier roof rated at 3,500 lb. A large lift for the roof. |
| Other Sunjoy models | varies | Send the model name. We confirm the frame material and crew before the visit. |
Many bolts and bars. Reviewers describe the roof framing as tedious, with many bolts and bars. We sort and count hardware first.
Instructions. Owners say the directions are hard to follow in places. We build from the manual for your exact model and check each step.
Several people. One reviewer reports two to four people for the pillars and main roof frame. We send a crew sized to the model.
Different constructions. A steel frame, a cedar frame and an aluminum frame go together differently. We confirm which one you have first.
A Sunjoy structure needs a level, firm base: a concrete slab, compacted gravel with pavers or a treated-lumber deck. A steel roof catches wind, so we anchor every structure with fasteners that match your surface. If you are unsure about your spot, send a photo and we will tell you what to change.
Every job is quoted individually, because the price depends on the model, the size, the site and any delivery. Send us:
