Rotted structural joist flange repair uncertainty and structural integrity assessment

“Should I be concerned with structural integrity of this composite balcony support beam? My townhouse has a balcony supported by a main structural beam which sits on 2 vertical piers: My building was constucted in 2011, the rest are 3-4 years older. All beams have quite visible sag : Same row of balconies in Dec 2024 - 8 years later. No, that's no lens distortion :(( I'm observing a lot of delamination along a particular line (@ ~1/3 height), also overall condition is pretty deteriorated (e.g. ch”

“Is it possible to repair or reinforce this short length (<1') of an I-joist's top flange that's slightly rotted? I'm redoing the floor in a bathroom on the second story of a two-story home. Underneath it's a 3/4" OSB subfloor on I-joists spaced 24" on center. I encountered a fair amount of mold damage and am in the process of replacing a section of the subfloor. Simply removing that has handled most of it, but in one spot next to the tub area (circled in red above), the mold has infiltrated down”

“Fixing sunken & floating box in a wall with metal studs I'm looking for a solution to fix a sunken and partially floating 2-gang box. The box is attached to a metal stud on the right side and floating on the left side. There's also a back wall ~4" behind the box. What I tried: Expanding foam through a hole in the box, to try to push the back of the box forward. However, the foam isn't sticking to the back wall. Tabs of light switches to pull the box using drywall on the top & bottom of the box. ”

“Should I bond ground in a subpanel with no feeder ground? Never bond a subpanel is what I always hear but I have an old school situation. The feeder to my well pump house has no grounding wire in the feeder - only one white and one black for 120V feed. Then for reasons I don’t understand one ground rod was installed and attached to the pump and outlet. The metal receptacle and disconnect are touching, so I guess they are sharing. It’s not bonded to the neutral anywhere and there is no other grou”

“Attaching a triangle/ring/hook to the back of a thin wooden plate A friend of mine has a painting on a sheet of wood, with dimensions WHD = 60cm x 80cm x 0.4cm . Yes, a thin piece of wood, no paper or canvas. It is not perfectly level either, and will not be framed (for this and aesthetic reasons). Now, I want to hang this painting on a wall. The wall side is not a problem, nothing out of the ordinary there. My problem is with attaching the hooks through which to run a string, on which the paini”

“Truss Hanger Squeak — Missing Fasteners or Connector Defect? I am looking for technical input on an upstairs floor-framing connection in a house built in Oregon in 2022. I discovered two very similar floor squeaks after removing the carpet in preparation for installing laminate flooring. One location is accessible through an existing HVAC register opening. The second location is not visible without opening the subfloor. The accessible connection includes: A short vertical web member approximatel”
