Short answer: Most kits are built by two to four people in a long day: brands quote 2 to 8 hours, owners report 6 to 12. The work that decides the result happens before the first box is opened: a level, solid base and the right anchors.
How long does it take to install a louvered pergola kit?
What each brand says about its reviewed kit, word for word where possible:
| Kit (score) | People | What the brand says |
|---|---|---|
 PERGOLUX Pergola 4 Pro9.5/10 | 2 | Pergolux lists 3–7 hours with 2 people; anchor bolts are not included; needs a standard 120 V outdoor outlet. |
 Hansø Aluminum Pergola9.3/10 | 2 | Hansø says two people, 2 to 4 hours, with pre-assembled parts. |
| Not stated | BILT app instructions; Backyard Discovery recommends consulting a professional for installation since it attaches to the house. | |
| Not stated | Guided 3D instructions in the BILT app; optional assembly service at $649 (scheduled separately). | |
 Mirador 111S8.7/10 | 2 | Mirador says two people with basic tools take about four hours; no rivets or welds; anchor bolts for a flat concrete surface are supplied. |
 Paragon Lugano8.5/10 | 2 | Paragon says 4–8 hours with two assemblers; pre-drilled anchor plates and hardware included. |
 Mirador 80S8.4/10 | 2 | Same Mirador guidance: two people, about four hours, anchor bolts for concrete supplied. |
 Domi Louvered Pergola8.2/10 | 2–3 | Domi says 2–3 people, a ladder and gloves, and recommends qualified technicians. |
 Purple Leaf Athena8.0/10 | 4–6 | Purple Leaf recommends 4–6 people and does not offer installation itself; it points to third-party assemblers. |
 EROMMY Louvered Pergola7.8/10 | 3 | EROMMY suggests 3 people and 4–8 hours. |
Owner reports are longer. A Hansø owner on r/patio: 6 to 7 hours with two people (2025). A Domi owner on r/landscaping: 12 hours with three handy people (April 2025). A PERGOLUX Sundream owner on r/gardening: 10 to 12 hours with four people (April 2026). Plan a full day, and a second one for the details.
Get the base right first
Every kit in our list anchors to a hard, flat surface. Mirador ships expansion bolts "to secure it to any flat concrete surface", and its ratings assume professional assembly and anchoring. Purple Leaf's 72 mph applies on "hardened floors" with expansion screws. Backyard Discovery's ratings require anchoring "as specified in the instruction manual". If you are pouring a new pad, let it cure fully before drilling, and check that it is level across the full footprint: a frame out of square leaks at the gutters and binds at the louvers.
On pavers or a deck, stop and ask the brand. A homeowner on r/landscaping found that his wall-mounted pergola would not clear a window once set on pavers, and his landscaper had to build raised concrete footings (2025). Measure heights against doors and windows before you order.
The order of the work
- Inventory. Open every box, count parts against the list, and photograph damage the day of delivery. One Purple Leaf owner received a few damaged pieces and snapped bolts during assembly (r/patio, July 2026).
- Posts and base plates. Mark the footprint, set the posts on their plates, check the diagonals.
- Beams. The heavy lift, and the reason most brands ask for more than two people. Steel kits weigh more: the Backyard Discovery Sarasota 12×10 is about 530 lb in total.
- Louvers and linkage. Then the crank, wand or motor. On motorized kits, cable routing inside the beam is the fiddly part, according to the r/gardening owner above.
- Square, level, then anchor. Domi asks owners to anchor "as soon as" the build is finished.
- Test the louvers through their full travel and run a hose over the closed roof to watch the gutters.

Tools and help
PERGOLUX lists a ladder, tape measure, level, power drill, Allen key and mounting bolts (which it does not supply). Add a masonry bit for your anchors, a rubber mallet, and two stable ladders. For crew size, follow the brand: two for Mirador and Hansø, two to three for Domi, three for EROMMY, four to six for Purple Leaf.
Before the truck arrives
These kits arrive by freight, in long, heavy boxes. Backyard Discovery ships the Sarasota 12×10 in four boxes about 117 inches long, the heaviest about 158 lb. Paragon ships the Lugano 10×12 in four boxes of 80 to 96 lb. The Hansø owner quoted above received nine boxes; the PERGOLUX owner on r/landscaping, eleven. Mirador's delivery agent calls within two business days to schedule; Domi delivers all boxes together by truck; EROMMY warns that multiple boxes may ship separately.
Clear a dry space in the garage, have two people for the unloading, and do not sign for visibly damaged boxes without noting it on the delivery slip.
Mistakes that cost a second weekend
- Anchoring before squaring. Check the diagonals and the level first; once the bolts are in, the frame is set.
- Forgetting the clearance. Measure doors, windows, gutters and light fixtures against the kit's height before you choose the spot.
- Overtightening into aluminum. Snug, then follow the manual's sequence; stripped threads are slow to fix.
- Skipping the water test. A hose on the closed roof shows a blocked gutter or a misaligned louver while the ladder is still out.
- Testing the motor last. On motorized kits, run the roof through its full travel before the covers go on the beams. PERGOLUX gives an operating range of −4°F to 104°F for its system.
After the build: the first weeks
The job is not quite done when the last louver clicks in. A few easy checks in the first weeks save a lot of trouble later:
- Look at the anchors after the first strong wind. Make sure nothing has moved at the base plates and the bolts are still snug.
- Run the louvers through their full travel once a week for the first month. A crank that gets stiff or a motor that stops short is easier to fix now than after a winter.
- Clear the gutters and post outlets after the first rain and again once the leaves fall.
- Keep the paperwork. Photos of the boxes on delivery day, the order number and the manual are what any warranty claim will start with.
If something is off, write to the brand with photos while the build is fresh. It is a far easier conversation in week two than in month ten.
Hire a pro or DIY?
Two brands sell assembly with the kit: PERGOLUX at $495 and Backyard Discovery at $649 (scheduled on a different day than delivery). Hansø has an installation team. Purple Leaf and Domi point to third-party installers. For a wall-mounted kit, Backyard Discovery recommends a professional, and the fastening to your house may be checked by your building department; see our permit guide. For a motorized kit, an electrician for the outlet is money well spent.

PERGOLUX lists $495 and Backyard Discovery $649 for their kits (November 2026). Independent installers quote locally.
