If your posting about sistering joists and replacing a sill plate you could probably diy

Sorry no recommendations on contractors in Londonderry though

Thank you! I've done a bunch of the sistering, but the jack up process for the sill plate scares me lol

If you have any house jacking and sill plate work, call Geddes. They have expertise and equipment for whole house moves and smaller tasks.

Yes, I’ve had contact with Geddes as well, and the experts bar none on this type of work.

Their portfolio of completed jobs is just amazing.
