    Roof design question

    I figured it out. The central beam looks small to you because it started life as a binder. The builder asked if we wanted the floor to be strong enough for an attic room, and said they'd just increase the joist size to suit. We said yes. So they dropped the binder and hung the joists off it...

    Roof design question

    Just a follow-up to this, 6 months later some of the joists seem to be making their way away from the bearer, in one case I can now get a finger in the gap. I've seen a crack appear in the gable wall but I don't know if that's related. I'd expect cracks in the walls that the joists rest on...

    Quotes vs Estimates

    I didn't ask what other trades are involved, but there is no electrical, or plastering work, this is only for the structural stuff. This was the first estimate, the guy was recommended to me. I had hoped to avoid getting loads of estimates for this, the amount looks reasonable without being...

    Quotes vs Estimates

    It's about 10,000 with the VAT. The report was a side of A4, not that much to read really. It seemed to be clear enough, and quite specific (that's the reason I paid the money to get it, didn't want any misunderstandings). I own the house.

    Quotes vs Estimates

    The estimate is based on the structural engineer's report + site visit. The report covers all the work to be done and lintel specifications. There are no drawings, since it's all just modifications/repairs. So by the sound of it I need to demand a quotation for most of the bits of work...

    Quotes vs Estimates

    I'm sure this has been done to death somewhere, but a search of the forum didn't reveal anything. Sorry if this is duplicating older discussions. Just wondering what the general consensus is about estimates in the building trade. I know everyone claims better to get a quote, however all...

    Dumb newbie questions on DIY UPVC window installation

    I fitted the unit in the pic I posted above, and it was more-or-less OK, although as luck would have it one of the screws snapped as I was tightening it. Think I'll stick with the Fischer fixings in future! :roll: But now I have a problem with another unit - it's got the glass built-in (no...

    Dumb newbie questions on DIY UPVC window installation

    Thanks, that's really helpful. I've just realised, after looking more closely, that the plugs have a small lip round them to stop them going through the frame. The ones I have are 10x140, so I guess that's going to be OK. Should they they go about like this?: About these packers, any...

    Dumb newbie questions on DIY UPVC window installation

    Hi all, This is for new-build, by the way, and I will be getting the work inspected afterwards. I've measured up and bought a window already from a local company just as a trial, but I'm a bit surprised as it has no fixing holes. Question #1 Where do the mounting holes go? I assume I...

    foundations depth....

    Having been in similar position (1930s house, lean-to beside) a spade depth may be optimistic :). As Static says, 1metre is standard, but your building control officer has the final say on this, so no point pricing up the job until you've spoken to him/her.

    Slipped purlin - Help please

    Some purlins rest on corbelling, so if you can manage to get it supported, you can always take a brick out below, put in a larger pad stone of the right size, then rest it on that. It may be easier than extending it. Be careful how you jack/support it though. It's possible that you want to...

    Roof design question

    The span is 4m. It's the width of the garage. It's not in the pic, but the rafters connect to the ends of those joists. So do you think those hangers are OK for this? I don't have much feel for the forces involved, weight of the wall, weight of the tiles, strength of the hangers when the...

    Roof design question

    No, it's not pre-manufactured, put together on site. Hopefully you can see this: //www.diynot.com/network/schiz/albums/4979/19855 It's 9-inch joists, rafters, and that's about it. No binders or purlins, but then it's a fairly small extension (garage with room above).
