Short Summary
Main recommendation: To change a light fixture over a stairwell safely, build a temporary platform that spans the stair opening so you can work from solid footing instead of leaning over with a stepladder. The presenter describes a platform built from 2x6 lumber, joist hangers, and plywood, which costs about $30 and takes about 10 minutes to assemble. The video also notes this is not engineered, so the viewer takes the risk.
Key Points
- A stepladder placed at the top of the stairs risks tipping over the opening, which can cause a serious fall.
- The platform extends the floor from the top of the staircase to the area directly under the light, so you can set a ladder on it.
- Lumber is held against the wall using point loads on the stair and wall supports rather than drilling into the wall.
- Cardboard is placed behind the supports to protect the walls from scratches.
- The presenter says in many jurisdictions a licensed electrician is required, but most jurisdictions allow homeowners to handle minor jobs like changing a fixture.
Details Worth Noting
- Concrete instructions:
- Measure from the floor to the ceiling (about 8 ft here) and transfer that height line onto the wall with tape.
- Use a 2x6 board as the main span, about 8 ft long (spanning just over 7 ft), and avoid drilling into the wall.
- Attach joist hangers to a rim joist and lumber pieces, screw them together with a plate, and staple cardboard to protect walls.
- Slide the 8 ft 2x6 up through the cradle, rest it in place, and fill the joist hanger screw holes.
- Screw a board down so the structure cannot slide off the wall.
- Lay 5/8 or 3/4 inch chipboard subfloor on top, then add flooring screws in the corners so nothing shifts.
- Turn off the light switch before working, remove the mounting plate, and disconnect the wires; leave the black and white connections alone if you are not comfortable making them.
- The presenter used 3/4 inch chipboard to match an existing renovation, but 5/8 inch is said to be fine.
- The brackets cost about $1 each, and the whole platform costs about $30.
- The presenter says the structure can carry a few thousand pounds, but the platform was not engineered.
Bottom Line
A temporary, low-cost platform spanning the stairwell lets you change an overhead fixture from stable footing, but because it is unengineered and involves electrical work, the viewer must weigh the risk and local rules before attempting it.
