joists

  1. Insulation
    I'm insulating a older house. The joists in the attic are both close together and unevenly spaced (between 14 and 14.5" apart, or 16 and 16.5" center line). I'd like to install r-38 or greater, but I'm having a hard time finding anything that fits. Knauf makes a 15" r-38, but it costs nearly...

    I am wanting to build a loft in a portion of my garage that is currently walled on 3 sides. The loft will be approximately 9'x9'. I was planning to attach a single 2x8 ledger board to each of the 3 garage walls and attach them directly to every garage stud (every 16") with LedgerLOK structural...

    Hi all-- I hope everyone is healthy and safe and staying sane. I'm trying to keep my mind and hands occupied by building a grade level deck that will connected by stairs to an upper landing. I've got the deck plans squared away and in for permitting, but I'm having trouble drawing the plans...

    (photos below) Hi All! The deck I am working on has two separate sections (basic rectangles), connected by a walkway that is just over 20ft long. It is 69" wide for most and 51" wide for the rest. The joists are hung via joist hangers connected the ledger board on one side, and the beam on...

    I'll just list the issues to make it (hopefully) quicker to read: Want to floor attic for simple light storage. Attic framed with 2x8 joists to a x8 beam running along the middle. Framers used 2x10 joists-hangers for hanging them: They now stick up over the beam/joist tops I can't quite...

    I have quite a few deck questions so might do a Pt. 2 to this post to share more pictures. Pictures attached are for a 3-year old deck and attached 3 season room. One pictures shows header. Believe that nails should be staggered. Unsure if correct fasteners and spacing was used i.e. should...

    I'm having a home built and saw this. The site supervisor said gravity would take care of it and it was no big deal. The other side is flush and looks great but this side I took a picture of is mind blowing to me. Shouldn't they use screws, why so many, no brackets, shouldn't it be flush too...

    Old farmhouse built in 1952. Actual 2x6 dimensional floor joists on 20" centers. The crawlspace is quite damp and there is a lot of mold and mildew on the existing joists and exposed subflooring. The house has settled quite a bit, needs leveling and some of the floor has a bit of bounce...

    My garage is 19' by 25', stick build. It is unfinished all around, without drywall or attic. The rafters going to the peak are 2 x 6, 24" on center. Then the joists/rafter ties going across the 19' span, parallel with the ground are 2 x 6, spaced 48" on center (connected @ every other...

    Sorry "advice" spelled wrong, and can't change it I had posted a thread a few weeks ago and my pictures posted were flipped, and was very confusing. I had never posted on a forum, but I am hoping someone can give me some advise on a very severe issue. We have recently had renovations done...

    Hello, I am planning to install drywall ceiling in my garage and I have a question about the support beams. The garage is 14x20. Currently there are only three 2x4 support beams going across the 14' width. There are also four flat pieces of wood going diagonally in the four corners of the...

    I've tried to wrap my head around cantilever rules, but I'm looking for input. I'm building a new deck that's 16x22. It's pressure treated pine, throughout. The 16' is the length of the joists away from the house. The joists meet the house with a ledger board that's a 2x10 lag-bolted to the...
  14. Flooring
    All, This is my first post here and I appreciate any ideas or thoughts on something that is bugging me, whether its correctable, and whether it makes sense to even try to correct. We own a 1984 colonial wherein the previous owners made some questionable repair work under our kitchen...

    I'm wanting to remove the laundry room and bathroom from this floor plan to open up the living room. Are these walls load bearing? Which way would you guess the floor joists run in this diagram? Could I run double headers over the length of the smaller wall that's enclosing the staircase, and...

    Whenever walking around in these two rooms the floors seems to shake and give slightly which causes furniture to rattle and move, it's not to the point of failure but is still worrying since everything in the room shakes, it's rather annoying. Can this possibly just be the floorboards...

    I would like to install decking to create an upper story in my detached garage. It would partly be for storing things and partly so my kids could have a place to play. I’m curious if the plan I have in mind makes sense. The garage walls are made of cinderblocks. The roof structure is made out...

    A friend wants me to put a deck on his front porch. The deck will be 12 by 6. He doesn't want to tear out the stoop. Any advise would be helpful. My thought was spacers between concrete and joists. Since I have to cut the joists above the stoop I want to be able to use the stoop as support...

    Hi all, I'm doing some work for a rather difficult client and am requesting some help. She purchased cheap stick on tiles for about 10 dollars a pack and wanted to stick those directly on her rotting floorboards.. I told her this would not really work since the floor is not flush and the...

    Hi. I have an investment 1965 brick ranch on unfinished basement. In the basement, there's extensive powder post beetle damage (bore holes) across all plywood subfloor, floor joists, and support beams. This was an old infestation exterminated via whole house fumigation. I have an engineer...
