I recently purchased a house and have noticed the floors seem to sag in certain spots. I notice in the basement that there are several sections where the joists were cut and then extended via tecos to the sill plate. Presumably because the sill plate needed to be replaced. I attached a photo of a small section showing what I'm describing. The majority of my basement is finished and can I can peek into a little space to allow the plumbing to run and there looks like there is a long stretch of this seemingly hack. Note, there was a significant house fire hence why the joists were painted/sealed.

1) is this a legit way to repair joists/sill plates?

2) is this safe?

There's no way we can say. The doubled joists may be sufficiently stout to carry the cross-beam. Or they may not. It's a question for an on-site engineer. Strategically there are no concerns, and there's nothing "hack" about it. It's no different than a break in the joists at any other beam. Almost every home in the U.S. has such a scenario.

By the way, those are called "joist hangers". Teco is a brand that manufacturers many products. I've never actually heard them called that, but I've heard the heavy-gauge 1-1/2" nails referred to as "teco nails".

  • Yes "Teco" is not a thing -- it is a brand (an adjective) used on things, such as connectors, hangers and fasteners made by Timber Engineering Company, and later by others, including United Steel Products, under that brand. – Upnorth Nov 30 '17 at 15:09
  • Simpson also makes things like that. – Harper Nov 30 '17 at 22:18
  • Thanks. I'm not a carpenter but I've heard several carpenters refer to "joist hangers" as tecos. Probably a regional thing (NY - LI). Again , I'm not a carpenter but I would think the right/better way would be to insert a new joist. – Paul Dec 2 '17 at 3:57
  • That's easier said than done. It's very difficult to get a large piece of lumber into a tight space from both ends at the same time. – isherwood Dec 2 '17 at 18:39
