Mandana Posted September 17, 2020 Share Posted September 17, 2020 Hi guys The ‘envelope’ on our SIPs house was completed yesterday ... that’s the great news. Not such great news is we’ve discovered some vents in the base course are missing. The builder will be sending the groundworkers back to carefully cut out blocks to retro-fit these vents. The problem is the base course has been rendered, so it’s a major job, and it may end up needing patching. We've told them if the render doesn’t look great afterwards they’ll need to re-render those areas which they don’t want to do. Their words were basically everyone needs to pull together and compromise. Our view is they screwed up and missed 9 vents. The architect has said 4 of those can be dropped so we now have 5 that need doing. Would you expect the render to look as good as it does now around the vents that were correctly installed, or accept it may not look so perfect? You can see two of the Rytons vents on the wall on the right for reference. Link to comment Share on other sites More sharing options...

nod Posted September 18, 2020 Share Posted September 18, 2020 If it’s only the base course it’s not a big deal Its still poor supervision on the builders pert Link to comment Share on other sites More sharing options...

Sadly Covid had a lot to do with that. We were lucky to get any work done at all, especially as our contractors were 6 hours from home so finding accommodation was a nightmare. Even so, they should have been supervised. Link to comment Share on other sites More sharing options...
Russell griffiths Posted September 18, 2020 Share Posted September 18, 2020 (edited) I would want it to look perfect if you have paid somebody to do it, if it looks inferior to the rest I would want that section re- rendered. Would it be be simpler to fit round vents so they can be drilled in using a core drill so the new round vent will cover the round hole, rather than them trying to cut out a square hole. Just a thought. Edited September 18, 2020 by Russell griffiths 2 Link to comment Share on other sites More sharing options...

My SIPS team had a stretch of water to contend with too... Getting anything done all seems really hard at the moment and I expect it isn't going to get easier any time soon. I agree with everyone else that since you're paying someone, then these problems ought not to even get as far as you other than in progress reports. "Pulling together" is fine, but the word "compromise" shouldn't imply a quality reduction. Perhaps this is why I struggle a bit to employ contractors. Are the whole of the telescopic vent thingies missing, or is it just the brick sized vent covers in the outer skin that are missing? Link to comment Share on other sites More sharing options...

The whole thing is missing - hole, sleeve and cover. Spoke to our architect this morning and he reckons the render will be fine if they are careful as it’s so fresh. It’s STO render - acrylic based for the SIPs, so it’s got movement in it and will be easy to touch up. Apparently! Link to comment Share on other sites More sharing options...
Vijay Posted September 18, 2020 Share Posted September 18, 2020 could they cut out the slots using an oscillating saw with a diamond blade? Link to comment Share on other sites More sharing options...

They’ve told us they will sort it so I’m presuming they’ll bring the right tools with them. Only trouble is they aren’t around the corner. They’re 6 hours away (without stops) so it’s not like they can fit it in around other jobs. Don’t envy them coming back (for the 3rd time) but if they’d been supervised and things were checked before the scaffolding went up we wouldn’t be in this pickle.

Not sure what you mean. There’s no weep holes in addition to the vents, if that’s what you mean? Just took this picture of one of the vents they missed and did knock through. Shame so many others were discovered after they left ? The second photo is a vent that was installed prior to the render application. And the third photo is of 2 more vents that were retro fitted but they weren’t in render, just under the (future) decking area. Link to comment Share on other sites More sharing options...
nod Posted September 18, 2020 Share Posted September 18, 2020 There should be drains leading from the cavity trays and weep vents piping through the render Link to comment Share on other sites More sharing options...

Our vents are in the base course allowing air to circulate under the house. We raised our house by 2’ onto beam and block so that’s what the ventilation is for. Our architect didn’t design any weep holes anywhere. Ours is a SIPs construction so we want to keep both air and water out. Link to comment Share on other sites More sharing options...
