Ok, I'll leave the MVHR until the dust has settled. I've been opening windows slightly when it hasn't been raining during the day and there is a lot less moisture on the windows now and mostly on the glass, not much on the frames and only when it gets cold overnight. I've left the dehumidfier running all the time and still trying to keep it warm inside and the air moving with fan heaters on when the windows are closed. Thanks for the advice. I sweep up the dust from chasing out the walls for electric cable in our first house with a brand new Dyson DC2. It didn't destroy the motor but I did cut out, I sassumed it overheated and the safety cut out did it's job. I think I had to change the filters but it kept working for many more years. I did learn the lesson and use workshop extractors after that!

I was going to get it switched on ASAP to help dry the house out, what are the problems with switching it on early? I thought it was in the paperwork with the MVHR unit that I read the suggestion to run it on full fan to help the house dry out. The house is slowly getting sealed up, I'm not getting much air movement and there is a lot of moisture inside. I did open the windows at the weekend as the weather was good and that seemed to help a lot but i didn't want to do that when it feels wetter outside than it does in. There are other things I would rather be working on thatn the MVHR so I can leave it until I have finished creating dust, but that is a long way off and we will be living in some parts before I have finished.

I hadn't thought about dust getting into the heat exchanger, does it create many issues? It is still very dusty around the house and it's going to be a long while before I stop producing dust but I really need to get the house dried out. Where do you find cone filters @JohnMo

OK thanks, I'll carry on with the insulation and get the MVHR running ASAP. I was wondering if others have experienced the same. I've already got a dehumidfier running upstairs 24/7 and the loft has enough ventilation to dry out any moisture going up there.

Yesterday I was drilling holes in the ceiling for the MVHR vent points and found there is quite a bit of moisture trapped just below the vapour barrier, between the plasterboard and VB. I realise this is what the VB is supposed to do but I'm wondering if seeing moisture trapped and the back of the PB being damp is normal a few weeks after the plaster was put on and the ceiling looks dry inside? The plasterers have only just finished but the upstairs ceilings were plastered a few weeks ago. I was intending to put the first layer of loft roll down this weekend and put the MVHR pipes in to help dry the house out but now I have seen the moisture I'm wondering if this is normal and will dry out from inside the house as the plaster dries fully, or if I need to leave the loft roll wrapped up for now and possibly split the VB in areas to let it dry out and then tape up the splits with airtight tape once it is dry? I have used Steico Multimembra5 above most of the ceilings which I believe should let some moisture through slowly, but above the bathrooms I used a green plastic VB from the local builders merchant. The plaster on the ceilings is onecoat at about 8mm thick, not multifinish, and that must mean more moisture in the plaster than normal.

I am still available tomorrow evening but will have more time between christmas and the 5th Jan.

I'm free on the 11th at the moment.

Are we on for this Thursday, probably today by the time anyone reads this? If so are we meeting at the Cherry Tree and at what time?

If only I had the time I'd love to!! oh, I've never played cricket so I'm not sure that would go too well. Plus one for visiting another build

Anything for an evening out and escape the build site sounds like a good plan at the moment😁

Yes, we watched it last week. It was interesting to see someone else using. I would be interested to know who their structural engineer was as the frame looked a lot less complicated than ours was.

I used Miktec in Stowmarket. Mik was very helpful and has done several of his own builds in the past.

No, but it looks great having those huge oak beams standing there on their own

That doesn't sound boring, the frame going up is exciting, or it was for us. I'd like to see your your oak frame before it is too covered over, maybe I can make time for a trip to Woodbridge then head up the A12 to IP17 next week. Wow, that sounds quite a while on one house, how many in the team? I don't have the front and back doors in their frames yet so still have a gale blowing through the house.

Thanks Alan, great to meet up with a few fellow self builders again and looking forward to the next one. I would be interested to visit your build, as I'm sure others would be too, and I would like to see how @G and J is getting on.
